compete the square to determine minum or maxuim value of function define by -x2+10x+5

Answers

Answer 1

Answer:

maximum value y = 30

Step-by-step explanation:

Given

- x² + 10x + 5

To complete the square the coefficient of the x² term must be 1

factor out - 1

= - (x² - 10x) + 5

To complete the square

add/subtract ( half the coefficient of the x- term )² to x² - 10x

= - (x² + 2(- 5)x + 25 - 25) + 5

= - (x - 5)² + 25 + 5

= - (x - 5)² + 30 ← in vertex form

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Hence vertex = (5, 30)

The max/ min occurs at the vertex

Since a < 0 then vertex is a maximum

Hence maximum value is y = 30

What are the 7 basic units of measurement in the metric system?

Answers

Answer:

The 7 basic units of measurement in the metric system are:

- second (s), measuring time

- meter (m), measuring length/distance

- kilogram (kg), measuring the mass/weight

- ampere (A), measuring electric current

- kelvin (K), for temperature.  kelvin uses the Celsius scale, but kelvin is the measure in the metric system for temperature because it starts at the absolute 0 (-273° C).

- mole (mol), the amount of a substance, used mostly in chemistry

and

- candela (cd), to measure light intensity

Final answer:

The 7 basic units of measurement in the metric system include meter, kilogram, second, ampere, kelvin, mole, and candela, serving as the foundation for scientific measurements.

Explanation:

The metric system, also known as the International System of Units (SI), is comprised of 7 basic units of measurement. These units form the foundation of the metric system and all other units are derived from these. The SI system is advantageous because it's based on powers of 10, making conversions between units straightforward.

The 7 Basic SI Units are:

Meter (m) - The unit of length.Kilogram (kg) - The unit of mass.Second (s) - The unit of time.Ampere (A) - The unit of electric current.Kelvin (K) - The unit of temperature.Mole (mol) - The unit of the amount of substance.Candela (cd) - The unit of luminous intensity.

Units such as millimeter, centimeter, and kilometer are derived from the basic unit of length, the meter, emphasizing the metric system's coherence and simplicity.

Which is true about x, the quotient of the division problem shown below?
81 divided by 918
The quotient contains a repeating decimal.
The quotient contains a terminating decimal.
The quotient is a whole number less than 11.
The quotient is a whole number greater than 11.

Answers

Answer:

The quotient contains a terminating decimal and The quotient is a whole number less than 11.

Step-by-step explanation:

To answer this one, it's mandatory to remember that quotient, is the outcome of a ratio: a number (r) over another (s) (different than 0). In this case:[tex]\frac{81}{918}[/tex]. So q is equal to =0.08823529411.

Analyzing the number: 0.08823529411

This is not a repeating decimal, but it is a terminating decimal for it has an end.

The quotient is also a whole number less than 11.

The Whole Set of numbers is made up of the following numbers W ={0,1,2,...} and 0 < 11. Therefore it is true.

The quotient of 81 divided by 918 is a decimal that contains repeating digits.

The question asks about the quotient of the division problem 81 divided by 918. To find out the nature of the quotient, we can perform the division. The result of this division is not a whole number since 81 cannot evenly divide 918. Therefore, we will be looking at a decimal result. When we carry out the division, we notice that the decimal will not terminate shortly; thus, we can infer that the pattern of digits will start to repeat at some point. This tells us that the quotient contains a repeating decimal. Therefore, the correct answer is that the quotient contains a repeating decimal. It is not a whole number, nor is it terminating, and the quotient will be less than 1 since 81 is less than 918.

Find three positive numbers whose sum is 12 and the sum of whose squares is as small as possible.

Answers

Answer:

4, 4, and 4.

The three positive numbers that satisfy the given conditions are

x = y = z = 4, and their sum is 12.

Given,

Sum of three numbers is 12.

Let the three positive numbers are x, y, and z.

1. To minimize the sum of their squares as

[tex]f(x, y, z) = x^2 + y^2 + z^2[/tex]

Subject to the constraint: Sum of three numbers is 12.

[tex]g(x, y, z) = x + y + z = 12[/tex]

2. Using Lagrangian function:

[tex]L(x, y, z, \lambda) = f(x, y, z) - \lambda(g(x, y, z) - 12)[/tex]

Substituting the value of f(x, y, z) = [tex]x^2 + y^2 + z^2[/tex] and g(x, y, z) = [tex]x + y + z - 12[/tex]  into Lagrangian function gives

[tex]L(x, y, z, \lambda) = (x^2+y^2+z^2) - \lambda (x+ y+ z - 12)[/tex]

3. Now, take partial derivatives of L with respect to x, y, z, and λ,

[tex]\(\frac{{\partial L}}{{\partial x}}[/tex] = [tex]2x - \lambda\)[/tex]

[tex]\(\frac{{\partial L}}{{\partial y}}[/tex] = [tex]2y - \lambda\)[/tex]

[tex]\(\frac{{\partial L}}{{\partial z}}[/tex] = [tex]2z - \lambda\)[/tex]

[tex]\(\frac{{\partial L}}{{\partial \lambda}}[/tex] = [tex]-(x + y + z - 12)[/tex]

4. Now, set each derivative to zero to find the critical points.

Equation 1:     [tex]\(\frac{{\partial L}}{{\partial x}}[/tex] = [tex]2x - \lambda\)[/tex] =0

Equation 2:     [tex]\(\frac{{\partial L}}{{\partial y}}[/tex] = [tex]2y - \lambda\)[/tex] = 0

Equation 3:     [tex]\(\frac{{\partial L}}{{\partial z}}[/tex] = [tex]2z - \lambda\)[/tex] = 0

Equation 4:     [tex]\(\frac{{\partial L}}{{\partial \lambda}}[/tex] = [tex]-(x + y + z - 12)[/tex] = 0

Solving equations (1), (2), and (3) we get

[tex]2x - \lambda\)[/tex] =0

        x = λ/2

[tex]2y - \lambda\)[/tex] = 0

        y = λ/2

[tex]2z - \lambda\)[/tex] = 0

         z = λ/2.

5. Substituting the value x = y = z = λ/2 into equation (4) gives

[tex]-(x + y + z - 12) = 0[/tex]

- [tex](\lambda/2 + \lambda/2 + \lambda/2 -12)= 0[/tex]

[tex]-(3\lambda/2 - 12) = 0[/tex]

[tex]3\lambda/2 = 12[/tex]

[tex]\lambda = 8[/tex]

So, x = y = z = λ/2 = 4.

Therefore, the three positive numbers are 4, 4 and 4.

An engineer determines that the angle of elevation from her position to the top of a tower is 57o. She measures the angle of elevation again from a point 43 meters farther from the tower and finds it to be 27o. Both positions are due east of the tower. Find the height of the tower.

Answers

Answer:

54.65m

Step-by-step explanation:

This is going to be extremely difficult to explain.  We have one large right triangle split up into 2 triangles:  the first one has a base angle of 57 with unknown base length (y) and unknown height (x), and the second one has a base angle of 27 with unknown base length of y + 43 and unknown height (x.  This is the same x from the first one and is what we are looking for...the height of the tower).  We can find the vertex angle of the first triangle because 180 - 90 - 57 = 33.  The side across from the 33 is y and the side adjacent to it is x so we have that tan33 = y/x.  Not enough yet to do anything with.  Our goal is to solve for that y value in order to sub it in to find x.  Next we have to use some geometry.  The larger triangle has a base angle of 27.  The angle within that triangle that is supplementary to the 57 degree angle is 180 - 57 = 123.  So now we have a triangle with 2 base angles measuring 123 and 27, and the vertex angle then is 180 - 123 - 27 = 30.  That vertex angle of 30 added to the vertex angle of the first triangle is 63 degrees total.  Now we can say that tan63 = (y+43)/x.  Now we have 2 equations with 2 unknowns that allows us to solve them simultaneously.  Solve each one for x.  If

[tex]tan33=\frac{y}{x}[/tex], then

[tex]x=\frac{y}{tan33}[/tex].

If

[tex]tan63=\frac{y+43}{x}[/tex], then

[tex]x=\frac{y+43}{tan63}[/tex]

Now that these both equal x and x = x, we can set them equal to each other and solve for y:

[tex]\frac{y}{tan33}=\frac{y+43}{tan63}[/tex]

Cross multiply to get

[tex]tan33(y+43)=ytan63[/tex]

Distribute through the parenthesis to get

y tan33 + 43 tan33 = y tan 63.

Now get the terms with the y in them on the same side and factor out the common y:

y(tan33 - tan63) = -43 tan33

Divide to get the following expression:

[tex]y=\frac{-43tan33}{(tan33-tan63)}[/tex]

This division gives you the fact that y = 64.264 m.  Now we add that to 43 to get the length of the large right triangle as 107.26444 m.  What we now is enough information to solve for the height of the tower:

[tex]tan27=\frac{x}{107.2644}[/tex]

and x = 56.65 m

The question is illustrated with the attached image.

First, calculate distance BC (x)

This is calculated using the following tan ratio

Next, calculate distance CD using the following tan ratio

[tex]\tan(27) = \frac{h}{CD}[/tex]

Make h the subject

[tex]h = CD \times \tan(27)[/tex]

From the attached image:

[tex]CD = x + 43[/tex]

So, we have:

[tex]h = (x + 43) \times \tan(27)[/tex]

Substitute [tex]h = x\tan(57)[/tex]

[tex]x \tan(57) = (x + 43) \times \tan(27)[/tex]

[tex]1.5398x = (x + 43) \times 0.5095[/tex]

Open brackets

[tex]1.5398x = 0.5095x + 21.9085[/tex]

Collect like terms

[tex]1.5398x - 0.5095x = 21.9085[/tex]

[tex]1.0303x = 21.9085[/tex]

Solve for x

[tex]x = \frac{21.9085}{1.0303}[/tex]

[tex]x = 21.2642[/tex]

Recall that:

[tex]h = x\tan(57)[/tex]

[tex]h = 21.2642 \times 1.5398[/tex]

[tex]h = 32.74[/tex]

Hence, the height of the tower is [tex]32.74 m[/tex]

To earn money, George types papers for college students. For regular term papers, he charges by the page: $1.50 each. For scientific and technical papers, he charges more because they take longer to type. If he types forty-five regular pages and thirty-six technical pages, how much will he earn? What other information is needed to solve this problem?

Answers

George's earnings from typing forty-five regular pages are $67.50. To calculate his total earnings, the charge per page for thirty-six technical papers is needed, which is not provided in the question.

To calculate how much George will earn for typing papers, we must know the charge per page for both regular and technical papers. For regular term papers, the charge has been provided: $1.50 per page. However, the charge for technical papers has not been specified. Thus, additional information is needed: the rate George charges per page for technical papers. Without this rate, we cannot accurately calculate his total earnings.

Given that George types forty-five regular pages, his earnings from regular papers can be calculated as:
45 pages *$1.50 per page = $67.50

As for the technical papers, we must have the rate per page to calculate his earnings from the thirty-six technical pages he typed. Once we have this rate, it would be a similar calculation to the one done for regular papers.

Find the number a such that the line x = a bisects the area under the curve y = 1/x2 for 1 ≤ x ≤ 4. 8 5​ (b) find the number b such that the line y = b bisects the area in part (a).

Answers

[tex]\( a = \frac{8}{5} \)[/tex] and  [tex]\( b = \frac{3}{8} \)[/tex].

To find the number asuch that the line x = a bisects the area under the curve [tex]\( y = \frac{1}{{x^2}} \)[/tex] for [tex]\( 1 \leq x \leq 4 \)[/tex], we first need to find the total area under the curve in that interval. Then, we'll find the value of a such that the area to the left of x = a is equal to the area to the right of x = a.

The total area under the curve [tex]\( y = \frac{1}{{x^2}} \)[/tex] from x = 1 to x = 4 is given by the definite integral:

[tex]\[ A = \int_{1}^{4} \frac{1}{{x^2}} \, dx \][/tex]

[tex]\[ A = \int_{1}^{4} x^{-2} \, dx \][/tex]

[tex]\[ A = \left[ -\frac{1}{x} \right]_{1}^{4} \][/tex]

[tex]\[ A = -\frac{1}{4} + \frac{1}{1} \][/tex]

[tex]\[ A = 1 - \frac{1}{4} \][/tex]

[tex]\[ A = \frac{3}{4} \][/tex]

So, the total area under the curve is [tex]\( \frac{3}{4} \)[/tex].

To bisect this area, the area to the left of x = a and the area to the right of x = a must each be [tex]\( \frac{1}{2} \)[/tex] of the total area.

Let's integrate from x = 1 to x = a to find the area to the left of \( x = a \), then set it equal to [tex]\( \frac{1}{2} \)[/tex] of the total area:

[tex]\[ \int_{1}^{a} \frac{1}{{x^2}} \, dx = \frac{1}{2} \cdot \frac{3}{4} \][/tex]

[tex]\[ \left[ -\frac{1}{x} \right]_{1}^{a} = \frac{3}{8} \][/tex]

[tex]\[ -\frac{1}{a} + \frac{1}{1} = \frac{3}{8} \][/tex]

[tex]\[ -\frac{1}{a} + 1 = \frac{3}{8} \][/tex]

[tex]\[ -\frac{1}{a} = \frac{3}{8} - 1 \][/tex]

[tex]\[ -\frac{1}{a} = \frac{3}{8} - \frac{8}{8} \][/tex]

[tex]\[ -\frac{1}{a} = \frac{-5}{8} \][/tex]

[tex]\[ \frac{1}{a} = \frac{5}{8} \][/tex]

[tex]\[ a = \frac{8}{5} \][/tex]

So, [tex]\( a = \frac{8}{5} \)[/tex].

Now, to find the number b such that the line y = b bisects the area, we need to find the value of b such that the area above the line y = b is equal to the area below the line y = b.

The total area under the curve is [tex]\( \frac{3}{4} \)[/tex]. Since the curve is symmetric about the x-axis, the line y = b must pass through the midpoint of the total area, which is [tex]\( \frac{3}{8} \)[/tex] above the x-axis.

So, [tex]\( b = \frac{3}{8} \)[/tex].

Identify m∠ADB. Help PLEASE!

Answers

Answer:

m<ADB = 25 degrees

Step-by-step explanation:

<ADB has two different intercepted arcs: AB and the unlabeled one that has a measure of 20. To find the actual measure of the angle, we must find the difference between these arcs and divide by 2.

70-20 = 50

50/2 = 25

Applying the angle of intersecting secants theorem, the measure of angle ADB in the diagram is: A. m∠ADB = 25°

What is the Angle of Intersecting Secants Theorem?

When two secants meet at a point outside a circle, the measure of angle formed at that point is half the positive difference of the intercepted arcs, based on the angle of intersecting secants theorem.

x =(6-√-12)/6=1-i/3√ 3 = 1.0000-0.5774i

x =(6+√-12)/6=1+i/3√ 3 = 1.0000+0.5774i

Step-by-step explanation:

Two imaginary solutions :  

x =(6+√-12)/6=1+i/3√ 3 = 1.0000+0.5774i

 or:  

x =(6-√-12)/6=1-i/3√ 3 = 1.0000-0.5774i

Two solutions were found :

x =(6-√-12)/6=1-i/3√ 3 = 1.0000-0.5774i

x =(6+√-12)/6=1+i/3√ 3 = 1.0000+0.5774i

Please help ASAP ! The question below

Answers

Answer:

a x = 14.3 units

Step-by-step explanation:

The Pythagorean theorem is

a^2 +b^2 = c^2  where a and b are the sides and c is the hypotenuse

x^2 + 14^2 = 20^2

x^2 +196 = 400

Subtract 196 from each side

x^2+196-196 = 400-196

x^2 =204

Take the square root of each side

sqrt(x^2) = sqrt(204)

x =14.28285686

To the nearest tenth

x = 14.3 units

The intersecting secants theorem says

[tex]PQ\cdot PR=PS\cdot PT[/tex]

[tex]\implies8(8+x)=4(24+4)[/tex]

[tex]\implies64+8x=112[/tex]

[tex]\implies8x=48[/tex]

[tex]\implies x=6[/tex]

It's clear from the image that [tex]PT=28[/tex], so the first option is correct.

###

Same as in the first problem; the intersecting theorems says

[tex]NM\cdot NL=NO\cdot NP[/tex]

[tex]\implies5(5+x)=3(3+17)[/tex]

[tex]\implies25+5x=60[/tex]

[tex]\implies5x=35[/tex]

[tex]\implies x=7[/tex]

so the third option is correct.

Answer:

x = 6; PR = 14; PT = 28

Four times Joe’s age plus 2 times Tim’s ageequals 50. Tim’s age is also 2 less than Joe’s age.How old is Joe?

Answers

Answer:

Joe is 9 years old

Step-by-step explanation:

We can start by creating two different equations, one for each fact that we know about their ages.

Say that J is Joe's age

Say that T is Tim's age

Our first equation would then be:

4J + 2T = 50

J - 2 = T

Now that we know that T is J - 2, we can plug that in to the first equation.

4J + 2(J - 2) = 50

We can simplify this equation to solve for J

4J + 2J - 4 = 50

6J = 54

J = 9

Joe is 9 years old

Does it take longer to learn in the winter when babies are bundled in clothes to restrict their movement? Data was collected from parents who brought their babies to New York University Infant Study Center to participate in one of a number of experiments between 1988 and 1991. Parents reported ages (in weeks) at which their child was first able to crawl a distance of four feet within one minute. The researchers also recorded the average outdoor temperature (in F) 6 months after the babies; date of birth. The resulting data were grouped by month of birth and all data for babies born on a given month averaged together. If you fit the least-squares line to the 12 data points (one for each month) you obtain the following results from a software package. Notice that the temperature given is taken as the explanatory variable and crawling age as the response variable. The dependent variable is the average crawling age.
