What is the least common multiple of 16 and 3?
​

Answer:

gets smaller.

Step-by-step explanation:

Quick Answer

To give you a short quick answer, the supplement is going to have to decrease or get smaller.

Example

Suppose the acute angle is 10 (anything under 90 will do).

Then the supplement is going to be 180 - 10 = 170

Now suppose the acute angle increase to 50 degrees.

That means the supplement will go from 180 - 50 = 130

Conclusion

As the acute angle gets bigger, the supplement gets smaller. This is an important idea to get clear. Bigger and Smaller or More or Less can be ugly little words, so anytime you come across them, pay attention. It will make your life in science so much easier.

Answer:

y = [tex]\frac{36}{121}[/tex]

Step-by-step explanation:

Given that y varies inversely as x then the equation relating them is

y = [tex]\frac{k}{x}[/tex] ← k is the constant of variation

To find k use the condition y = 18 when x = 4

k = yx = 18 × 4 = 72, so

y = [tex]\frac{72}{x}[/tex] ← equation of variation

When x = 242, then

y = [tex]\frac{72}{242}[/tex] = [tex]\frac{36}{121}[/tex]

Answer:

x = 1/2 and x = 9/2

Step-by-step explanation:

To solve this equation: |2x-5|=4 we need two evaluate two cases:

|2x-5| = 2x-5 when x>5/2 ✅

|2x-5| = -2x+5 when x<5/2✅

Then, if x>5/2:

2x-5 = 4 ➡ x = 9/2

Then, if x>5/2:

-2x+5 = 4 ➡ x = 1/2

Then, the two solutions are:  x = 1/2 and x = 9/2

The functions ordered from least to greatest y-intercept are

1) h(x) -----> y-intercept -1

2) g(x) ----> y-intercept 1

3) f(x) ----> y-intercept 2

Step-by-step explanation:

we know that

The y-intercept (or initial value) is the value of y when the value of x is equal to zero

Part 1) Find the y-intercept of g(x)

Remember that the initial value of the fuction is equal to the y-intercept

a=1 -----> is the initial value

therefore

The y-intercept of g(x) is 1

Part 2) Find the y-intercept of f(x)

Observing the table

For x=0

f(x)=2

therefore

The y-intercept of f(x) is 2

Part 3) Find the y-intercept of h(x)

Observing the graph

For x=0

h(x)=-1

therefore

The y-intercept of h(x) is -1

Answer:

v = √( [tex]\frac{2E}{m}[/tex] )

Step-by-step explanation:

E=1/2mv²

v² = ( [tex]\frac{2E}{m}[/tex] )

v = √( [tex]\frac{2E}{m}[/tex] )

Answer:

[tex]v=\sqrt{\frac{2E}{m}}[/tex]

Step-by-step explanation:

[tex]E= \frac{1}{2} mv^2[/tex]

Solve the equation for v

To remove fraction , multiply both sides by 2

[tex]2 \cdot E= \frac{1}{2} mv^2 \cdot 2[/tex]

[tex]2E=mv^2[/tex]

Divide both sides by 'm' to isolate v^2

[tex] \frac{2E}{m}=v^2[/tex]

Now to remove square from V, we take square root on both sides

[tex]\sqrt{\frac{2E}{m}} =v[/tex]

[tex]v=\sqrt{\frac{2E}{m}}[/tex]

When a line is represented in the slope intercept formula as in the question you must remember that it is always set up like so...

y = mx + b

m is the slope and b is the y-intercept of the line

Since in the equation y = -3x + 1 the m is -3 then the slope is -3

Answer:

$7.5

Step-by-step explanation:

If Colleen develops 350 pictures (x):

1. If member, cost is:

[tex]0.15x + 10\\=0.15(350)+10\\=62.5[/tex]

2. If not a member, cost is:

[tex]0.2x\\=0.2(350)\\=70[/tex]

Hence, Colleen pays 70 - 62.5 = 7.5 more by not being a member.

Answer:

$7.5.

Step-by-step explanation:

We have been given that Colleen plans to print x pictures from her camera at a drug store.

The difference of cost for non-member and member would be difference of both expressions as:

[tex]0.2x-(0.15x+10)=0.05x-10[/tex]

To find the difference for developing 350 pictures without being member and non-member, we will substitute [tex]x=350[/tex] in expression [tex]0.05x-10[/tex]:

[tex]0.05(350)-10=17.5-10=7.5[/tex]

Therefore, Colleen will pay $7.5, while not being a member and developing 350 pictures.

ANSWER

[tex]\frac{ {y}^{2} }{ 25} - \frac{ {x}^{2} }{ 64} = 1 [/tex]

EXPLANATION

The given hyperbola has a vertical transverse axis and its center is at the origin.

The standard equation of such a parabola is:

[tex] \frac{ {y}^{2} }{ {a}^{2} } - \frac{ {x}^{2} }{ {b}^{2} } = 1 [/tex]

Where 2a=10 is the length of the transverse axis and 2b=16 is the length of the conjugate axis.

This implies that

[tex]a = 5 \: \: and \: \: b = 8[/tex]

Hence the required equation of the hyperbola is:

[tex]\frac{ {y}^{2} }{ {5}^{2} } - \frac{ {x}^{2} }{ {8}^{2} } = 1 [/tex]

This simplifies to,

[tex]\frac{ {y}^{2} }{ 25} - \frac{ {x}^{2} }{ 64} = 1 [/tex]

Answer:

[tex]\frac{(y^2}{25}-\frac{x^2}{64}=1[/tex]

Step-by-step explanation:

We have been given an image of a hyperbola. We are asked to write an equation for our given hyperbola.

We can see that our given hyperbola is a vertical hyperbola as it opens upwards and downwards.

We know that equation of a vertical hyperbola is in form [tex]\frac{(y-k)^2}{a^2}-\frac{(x-h)^2}{b^2}=1[/tex], where, [tex](h,k)[/tex] represents center of hyperbola.

'a' is vertex of hyperbola and 'b' is co-vertex.

We can see that center of parabola is at origin (0,0).

We can see that vertex of parabola is at point [tex](0,5)\text{ and }(0,-5)[/tex], so value of a is 5.

We can see that co-vertex of parabola is at point [tex](8,0)\text{ and }(-8,0)[/tex], so value of b is 8.

[tex]\frac{(y-0)^2}{5^2}-\frac{(x-0)^2}{8^2}=1[/tex]

Therefore, our required equation would be [tex]\frac{(y^2}{25}-\frac{x^2}{64}=1[/tex].

Answer:

Step-by-step explanation:

(f · g)(x) = f(x) · g(x)

We have f(x) = 4x² and g(x) = x + 1. Substitute:

(f · g)(x) = (4x²)(x + 1)    use the distributive property

(f · g)(x) = (4x²)(x) + (4x²)(1)

(f · g)(x) = 4x³ + 4x²

Answer:

5th term is 35a^4b^3

Step-by-step explanation:

We are given

x=a,

y =b

n=7

and k= 4 since we have to find 5th term but k starts from zero

putting the values

[tex]={7\choose 4}a^4b^{7-4}\\={7\choose 4}a^4b^{3}\\=\frac{7!}{4!(7-4)!}a^4b^3\\=35a^4b^3[/tex]

Answer: Perimeter = 135 units      Area = 1200 Square units

Step-by-step explanation: I think you want the perimeter and area of XYZ so that's what I will answer for.

First, we are given that ABC and XYZ are proportional and that their longest sides are 24 units and 60 units respectively.

Using this, we can say XYZ = ABC * 5/2 (60/24 = 5/2)

Therefore, the other two sides of XYZ are 50 and 25.

We can get the perimeter using 60 + 50 + 25, that equals 135 units

Next, since the height of ABC was 8 units with 24 units being its base, it's likely safe to say the height = 1/3 base

We will apply with to triangle XYZ, height = 1/3 * 60 = 20

20 units * 60 units = 1200 square units

The perimeter and area of the ΔXYZ are 135 units and 600 sq. units. Where similar triangles are related by a scale factor.

The ratio of their respective sides of two similar triangles gives the scale factor. I.e.,

Consider ΔABC and ΔDEF are two similar triangles

Then its scale factor = DE/AB = EF/BC = DF/AC

The scale factor is also defined as follows:

(Scale factor)² = (Area of the triangle DEF)/(Area of the triangle ABC)

or

Scale factor = (perimeter of ΔDEF)/(perimeter of ΔABC)

Given that the sides of the triangle ABC are 10 units, 20 units, and 24 units. The longest side is 24 units.

The triangle XYZ has the longest side of length 60 units.

Since ΔABC ~ ΔXYZ

So, the ratio of their longest sides gives the scale factor. I.e.,

Scale factor = 60/24 = 2.5

The perimeter of the ΔXYZ is calculated by

Scale factor = (perimeter of the ΔXYZ)/(perimeter of the ΔABC)

⇒ 2.5 = (perimeter of the ΔXYZ)/(10 + 20 + 24)

⇒ perimeter of the ΔXYZ = 2.5 × 54

∴ the perimeter of the ΔXYZ = 135 units

The area of the ΔXYZ is calculated by

(Scale factor)² = (area of the ΔXYZ)/(area of the ΔABC)

So, the area of the ΔABC, whose height h = 8 units and base b = 24 units is

Area of the ΔABC = 1/2 × b × h

                              = 1/2 × 24 × 8

                              = 96 sq. units

Thus,

(Scale factor)² = (area of the ΔXYZ)/(area of the ΔABC)

⇒ (2.5)² =  (area of the ΔXYZ)/(96)

⇒  area of the ΔXYZ = (2.5)² × 96

∴  area of the ΔXYZ = 600 sq units

Thus, the perimeter and area of the ΔXYZ are 135 units and 600 sq. units.

Part 1) The inequality that describes the relationship between the number of cookies each one of them has is [tex]x^{2} -30x+224\geq 0[/tex]

Part 2) Jessica has at least 2 cookies more than Martha

Step-by-step explanation:

Part 1) Find the inequality that describes the relationship between the number of cookies each one of them has

Let

x----> the number of cookies when Jessica started

30-x ----> the number of cookies when Martha started

we know that

Each of them ate 6 cookies from their bag

so

The cookies left in each bag are

(x-6)  ----> Jessica

and (30-x-6)=(24-x) ---> Martha

The product is equal to (x-6)(24-x)

The product of the number of cookies left in each bag is not more than 80.

so

[tex](x-6)(24-x)\leq 80\\ \\24x-x^{2}-144+6x\leq 80\\ \\-x^{2} +30x-144-80\leq 0\\ \\-x^{2} +30x-224\leq 0[/tex]

Multiply by -1 both sides

[tex]x^{2} -30x+224\geq 0[/tex]

Part 2) Solve the quadratic equation

[tex]x^{2} -30x+224\geq 0[/tex]

Solve by graphing

The solution is x=16 cookies

so

(30-x)=30-16=14 cookies

therefore

The number of cookies when Jessica started was 16 cookies

The number of cookies when Martha started was 14 cookies

The number of cookies left in each bag  is equal to

Jessica

16-6=10 cookies

Martha

14-6=8 cookies

Jessica has at least 2 cookies more than Martha

The probability of selecting a football card and then a basketball card from the grab bag is (a) 0.21.

We employ the idea of independent events to calculate probability. Given that there are 3 football cards among the total of 10 cards, the chance of choosing one during the initial draw is [tex]\frac{3}{10}[/tex]. The likelihood of choosing a basketball card on the second draw is [tex]\frac{7}{10}[/tex] since the card is changed before the second draw. When these probabilities are added together, the result is [tex]\frac{3}{10}* \frac{7}{10} = \frac{21}{100}[/tex] = 0.21. As a result, option (a) corresponds to the right response, which is 0.21.

Answer:

It is choice A.

Step-by-step explanation:

The general form is (x - h)^2 / a^2 + (x - k)^2/b^2 = 1 where (h, k) is the center, 2a = major axis and 2b = minor axis.

The ellipse in the question has a^2 > b^2 so the major axis is  parallel to the x axis.

The minor axis  which is parallel to the y-axis is of length 10 so b^2 = (1/2 * 10)^2

= 25 so we can eliminate C.

The center of the ellipse = the midpoint of a line joining the focii so it is:

( 3+ 7)/2,  6)

= (5,6).

As (h, k) is the center we have h = 5 and k = 6.

So it is choice A.

The equation of the eclipse will be [tex]\frac{(x-5)^2}{29} +\frac{(y-6)^2}{25} =1[/tex]  i.e. option A.

The standard equation of the ellipse is [tex]\frac{(x-h)^2}{a^2} +\frac{(y-k)^2}{b^2} =1[/tex].

Here,  

(h, k) is the center, and 2a and 2b are major and minor axis.

We have,

Length of minor axis = 10

i.e. 2b = 10

And,  b = 5

And,

Foci (c) located at (3,6) and (7,6),

i.e. Major axis is parallel to x-axis.   [Because y is constant]

And,

The foci (c) always lie on the major axis.

And,

c² = a² - b²

Now,

The center of an ellipse is the midpoint of both the major and minor axes, i.e.  the midpoint of a line joining the foci (c),

i.e. Center [tex]=( \frac{x_1 + x_2 }{2}, \frac{y_1 + y_2}{2}) =( \frac{3+7}{2}, \frac{6+6}{2}) =(5, 6)[/tex]

Now,

Foci (c) = 5 - 3 = 2

So,

c² = a² - b²

i.e.

2² = a² - 5²

4 =  a² - 25

⇒  a² = 29  

And, b² = 5² = 25

So,

h = 5 and k = 6

Now,

Putting the values in the standard form of equation of the ellipse,

i.e.

[tex]\frac{(x-h)^2}{a^2} +\frac{(y-k)^2}{b^2} =1[/tex]

i.e.

[tex]\frac{(x-5)^2}{29} +\frac{(y-6)^2}{25} =1[/tex]

So, this is the equation of the eclipse i.e. option A.

Hence, we can say that the equation of the eclipse will be [tex]\frac{(x-5)^2}{29} +\frac{(y-6)^2}{25} =1[/tex]  i.e. option A.

I had this question and got it right.

To factor the polynomial x^2 + 5x - 14, use the method of finding two numbers that multiply to give the constant term and add up to give the coefficient of x. For x^2 - 10x + 16, use the same method to find the two numbers.

To factor the polynomial x^2 + 5x - 14, we look for two numbers that multiply to give the constant term (-14) and add up to give the coefficient of x (5). In this case, the numbers are 7 and -2. So we can rewrite the polynomial as (x + 7)(x - 2).

To factor the polynomial x^2 - 10x + 16, we look for two numbers that multiply to give the constant term (16) and add up to give the coefficient of x (-10). In this case, the numbers are -2 and -8. So we can rewrite the polynomial as (x - 2)(x - 8).

The basic formula to calculate a student's GPA is the addition of all grade points in completed courses divided by the number of classes completed.

A student's GPA is calculated by adding up the numeric equivalent of each grade and dividing by the total number of classes. For example, using a system where A = 4, B = 3, C = 2, D = 1 and F = 0, a student with one A and one B would have a GPA of (4+3)/2 = 3.5.

The basic formula to calculate a student's GPA (grade point average) typically involves totalling the numeric representation of each individual grade, and then dividing that total by the total number of classes taken.

For instance, if we use a regular American system where A = 4, B = 3, C = 2, D = 1 and F = 0, and a student has one A and one B, their GPA would be the sum of these points (4 + 3 = 7) divided by the number of classes (2) which equals 3.5. Therefore, this student's GPA is 3.5.

Answer:

(x-5)^2+(y+4)^2=100

Step-by-step explanation:

As we know the given points

Center = (5, -4)

and

Point on circle = (-3,2)

The distance between point on circle and center will give us the radius of circle

So,

The formula for distance is:

[tex]\sqrt{(x_{2}-x_{1} )^{2}+(y_{2}-y_{1})^{2}}\\Taking\ center\ as\ point\ 1\ and\ the\ other\ point\ as\ point\ 2\\d=\sqrt{(-3-5)^{2}+(2-(-4))^{2}}\\d=\sqrt{(-8)^{2}+(2+4)^{2}}\\d=\sqrt{(-8)^{2}+(6)^{2}}\\\\d=\sqrt{64+36}\\d=\sqrt{100} \\ d=10\\So\ the\ radius\ is\ 10[/tex]

The standard form of equation of circle is:

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

where h and k are the coordinates of the center. So putting in the value:

[tex](x-5)^{2}+(y-(-4))^{2}=(10)^{2}\\(x-5)^{2}+(y+4)^{2}=100[/tex]
