Answer:

The turning point is (2,8)

Step-by-step explanation:

we know that

The general equation of the substance's temperature is equal to

[tex]T(x)=(x-h)^{3}+k[/tex]

where

(h,k) is the vertex (turning point)

In this problem we have

[tex]T(x)=(x-2)^{3}+8[/tex]

so

(h,k)=(2,8)

therefore

Answer:

Step-by-step explanation:

(1) y = 4x + 5 and (2) y = 4x - 5

substitute (1) to (2):

4x + 5 = 4x - 5         subtract 4x from both sides

5 = -5      FALSE (no solution)

(1) y = 4x + 5 and (2) 2y = 8x + 10

substitute (1) to (2):

2(4x + 5) = 8x + 10          divide both sides by 2

4x + 5 = 4x + 5         subtract 4x from both sides

5 = 5   TRUE (infinitely many solutions)

(1) y = 4x + 5 and (2) y = x + 5

substitute (1) to (2):

4x + 5 = x + 5         subtract 5 from both sides

4x = x          subtract x from both sides

3x = 0         divide both sides by 3

x = 0

Put it to (2):

y = 0 + 5 = 5

One solution (0, 5)

(1) y = 4x + 5 and (2) y = 8x + 10

substitute (1) to (2):

4x + 5 = 8x + 10       subtract 5 from both sides

4x = 8x + 5       subtract 8x from both sides

-4x = 5           divide both sides by (-4)

x = -1.25

Put it to (1):

y = 4(-1.25) + 5 = -5 + 5 = 0

One solution (-1.25, 0)

Answer:

the desired result is (p + q) = (3 + 5) = 8

Step-by-step explanation:

Let's solve this system of linear equations in the usual way:  find the values of p and q.  Then find (p + q) as a numerical result.

Solve:

2p+q=11

p+2q=13

Multiply the second equation by -2:

2p + q = 11

-2p - 4q = -26

Combining these two equations results in -3q = -15, and so q must be 5.

Subbing 5 for q in the first equation, we get:

2p + 5 = 11, or 2p = 6.  Then p = 3.

Then the desired result is (p + q) = (3 + 5) = 8

The required answer is  p + q is equal to 8 by  solving systems of equations 2p+q=11 and p+2q=13. The required sum is 8.

To find the value of p + q, we can use the given system of equations:

Equation 1: 2p + q = 11

Equation 2: p + 2q = 13

We can solve this system of equations by either the substitution method or the elimination method. Let's use the elimination method:

Multiply Equation 1 by 2:

2(2p + q) = 2(11)

4p + 2q = 22 ...(Equation 3)

Subtract Equation 2 from Equation 3:

(4p + 2q) - (p + 2q) = 22 - 13

4p + 2q - p - 2q = 9

3p = 9

Divide both sides by 3 to solve for p:

p = 9 / 3

p = 3

Now substitute the value of p back into Equation 1:

2(3) + q = 11

6 + q = 11

Subtract 6 from both sides to solve for q:

q = 11 - 6

q = 5

Finally, we can find p + q:

p + q = 3 + 5

p + q = 8

Therefore, p + q is equal to 8 solving systems of equations 2p+q=11 and p+2q=13. The required sum is 8.

Step-by-step explanation:

we know that

If two vectors are orthogonal, then the dot product ( or scalar product) of the vectors is equal to zero

so

Let

a (x1,y1)  and b(x2,y2)

The dot product is equal to

a.b=(x1*x2+y1*y2)

Verify each case

therefore

(1,-2) is orthogonal to the given vector

case B) (2,1) with (-3,6)

(2,1).(-3,6)=(2)*(-3)+(1)(6)=-6+6=0

therefore

(-3,6) is orthogonal to the given vector

case C) (2,1) with (1,2)

(2,1).(1,2)=(2)*(1)+(1)(2)=2+2=4

therefore

(1,2) is not orthogonal to the given vector

Step-by-step explanation:

Translating the half to symbols would be 1/2. Therefore, your answer is 1/2(n)

Hope this helps!

Answer:

1/2n

Step-by-step explanation:

half of n

of means multiply

1/2 * n

n/2

First you must distribute the numbers outside the parentheses to the numbers inside the parentheses

Let's start with the first one:

9(x-2) + 3(5-2x) = 2

9(x - 2)  

9*x + 9*-2

9x + (-18)

9x - 18

so...

9x - 18 +  3(5-2x) = 2

Now on to the second set of parentheses:

9x - 18 + 3(5-2x) = 2

3(5 - 2x)

3*5 + 3*-2x

15 + (-6x)

15 - 6x

so...

9x - 18 + 15 - 6x = 2

Now you must combine like terms. This means the numbers with the same variables must be combined...

First set of like terms:

9x - 18 + 15 - 6x = 2

9x + (-6x)

3x

so...

3x - 18 + 15 = 2

Second set of like terms:

3x - 18 + 15 = 2

-18 + 15

-3

so...

3x - 3 = 2

Now bring -3 to the right side by adding 3 to both sides (what you do on one side you must do to the other). Since -3 is being negative on the left side, addition (the opposite of negative/subtraction) will cancel it out (make it zero) from the left side and bring it over to the right side.

3x + (- 3 + 3) = 2 + 3

3x + 0 =5

3x = 5

Next divide 3 to both sides to finish isolating x. Since 3 is being multiplied by x, division (the opposite of multiplication) will cancel 3 out (in this case it will make 3 one) from the left side and bring it over to the right side.

3x/3 = 5/3

x = [tex]\frac{5}{3}[/tex]

Answer:

x²+y²=16

Step-by-step explanation:

the general equation for a circle is given as :

(x−h)²+(y−k)²=r²

where (h, k) is the coordinate of the center of the circle and r is the radius

in this case h=0, k=0 and r = 4

equation becomes

x²+y²=4²

or

x²+y²=16

Answer: Last option.

Step-by-step explanation:

The equation of a circle in Center-radius form is:

[tex](x-h)^2+(y-k)^2=r^2[/tex]

Where the center is at the point (h,k) and "r" is the radius.

If the center of this circle is at the origin, means that:

[tex]h=0\\k=0[/tex]

Since the radius is 4, then:

[tex]r=4[/tex]

Now we need to substitute these values into the equation of the circle.

[tex](x-0)^2+(y-0)^2=(4)^2[/tex]

Simplifying the equation, we get:

[tex]x^2+y^2=16[/tex]

This matches with the last option.

Answer:

7.1 inches

Step-by-step explanation:

An Isosceles right triangle is one with two sides equal and the angles equal too.The angles in this case are 45°

For this question, to get the hypotenuse, you apply the Pythagorean relationship where the legs will be represented by a and b where as the hypotenuse will be represented by c.

[tex]a^2+b^2=c^2\\[/tex]

Given;

One leg = 5 inches, but you know that in this triangle, the two sides are equal, hence the other side/leg is 5 inches.

Lets take one side of the triangle as a=5 inches

The other side as b=5 inches

The hypotenuse as c=?

Apply the expression;

[tex]a^2+b^2=c^2\\\\5^2+5^2=c^2\\\\25+25=c^2\\\\50=c^2\\\\c=\sqrt{50} =7.071[/tex]

To the nearest tenth 7.071 = 7.1 inches

Answer:

a= -6

Step-by-step explanation:

Given

a=2+3a+10

In order to find the value of a, we have to isolate a on a single side of the equation

So,

subtracting 3a from both sides

a-3a = 2+10+3a-3a

=>a-3a=12

=> -2a = 12

Dividing both sides by -2

=> -2a/-2 = 12/-2

=> a = -6

The value of a in the given equation is -6 ..

Answer:

D

Step-by-step explanation:

point-slope form is y-y1=m(x-x1) . since the slope is 2 and not -2, you can automatically eliminate choices A and C. since the y-value in the point, (1,-1), is -1, you will add it to y because you are subtracting a negative. (- - = +) therefore, the final equation, in point-slope form, is y+1=2(x-1), or answer choice D.

The answers are:

[tex]AbsoluteError=20mhz[/tex]

[tex]RelativeError=2.5(Percent)[/tex]

To solve the problem we need to remember that the absolute error is the difference between the expected value and the measured value, also, to calculate the relative error we first need to calculate the absolute error, and then, divide it by the expected measure.

So, calculating we have:

[tex]AbsoluteError=Expected-MeasuredValue\\\\AbsoluteError=800mhz-820mhz=-20mhz[/tex]

We can see that we obtained a negative value, however, when we are working with "absolute" values, the negative symbol is discarded, so, we have that:

[tex]AbsoluteError=20mhz[/tex]

Now, to calculate the relative error, we need to use the following formula:

[tex]RelativeError=\frac{AbsoluteError}{ExpectedValue}*100\\\\RelativeError=\frac{20}{800}*100=0.025*100=2.5(Percent)[/tex]

So, we have that the relative error is equal to 2.5%.

Hence, we have that:

[tex]AbsoluteError=20mhz[/tex]

[tex]RelativeError=2.5(Percent)[/tex]

Have a nice day!

Absolute error is 20 MHz and relative error is 2.5%.

Absolute error: Absolute error is the difference between the measured value and the actual value. In this case, the absolute error is 820 MHz - 800 MHz = 20 MHz.

Relative error: Relative error is the ratio of the absolute error to the actual value. The relative error can be calculated as (820 MHz - 800 MHz) / 800 MHz = 0.025 or 2.5%.

Answer:   [tex]\bold{\dfrac{1}{19}}[/tex]

Step-by-step explanation:

Let x represent the quantity of yellow cubes

Yellow: x

Blue: three times yellow --> 3x

Green: five times blue --> 5(3x) = 15x

Yellow + Blue + Green = Total cubes

    x      +   3x  +    15x   =       19x

[tex]Probability=\dfrac{yellow}{total}=\dfrac{x}{19x}=\large\boxed{\dfrac{1}{19}}[/tex]

The probability of Sarah taking out a yellow cube from the bag is 0.7 or 5/7.

The fraction of favorable outcomes of an event to the total number of outcomes of the event is said to be the probability. The fraction can also be written in the simplest form.

P(E)= n(E)/n(S) where E -event, n(E) - favorable outcomes and n(S) is the total outcomes.

It is given that a bag contains blue cubes, yellow cubes, and green cubes.

Consider the number of blue cubes = n

So, the number of yellow cubes = 3 times as many as blue cubes

                                                     = 3n

Then, 5 times as many as green cubes = blue cubes

⇒ number of green cubes = n/5

Then the total number of cubes in the bag

= n + 3n + n/5

⇒ [5n + 15n + n]/5

⇒ 21n/5

Then the probability of taking out a yellow cube = (possible outcomes of a yellow cube)/(total number of cubes)

⇒ [tex]\frac{(3n)}{(21n/5)}[/tex]

⇒ 15n/21n

⇒ 5/7

∴ The probability of taking out a yellow cube = 5/7 = 0.7.

B) Bisector of an angle  ~apex

Step-by-step explanation:

Option B is correct, bisector of an angle is defined as the set of all points in a plane that are equidistant from the two sides of a given angle.

A system that uses one or more numbers, or coordinates, to uniquely determine the position of the points or other geometric elements on a manifold such as Euclidean space.

The bisector of an angle is a straight line or a line segment that divides an angle into two equal angles.

In other words, the bisector of an angle is the set of all points in a plane that are equidistant from the two sides of a given angle.

The geometric object defined as the set of all points in a plane that are equidistant from the two sides of a given angle is the Bisector of an angle.
