Find the area of a circle with radius 7 yd.
Use the value 3.14 forn, and do not round your answer.
Be sure to include the correct unit in your answer.​

Answer:

(C)y=0

Step-by-step explanation:

An exponential function of the form [tex]f(x) = a (b^x) + c[/tex] always has a horizontal asymptote at y = c.

Given our function [tex]y=4^x[/tex]

Comparing with the form,  [tex]f(x) = a (b^x) + c[/tex], we observe that c=0.

Therefore, the exponential function has an asymptote at y=0.

The correct option is C.

Answer:

y=9 7/15

Step-by-step explanation:

y + 3 7/15 = 12 14/15 - 8/15

y + 3 7/15 = 12 14/15

y + 3 7/15 = 12 14/15

   - 3 7/15  - 3 7/15

y             =  9 7/15

Answer:

D

Step-by-step explanation:

Refer to picture.

When graph of y = x is transformed to y = x - 13,

U can visualise it by drawing the before and after transformed graphs to compare in order to deduce the answer.

From the picture, you will realise that when x is unchanged, I'm this case I'm using points x=0 and x=13, the value of the y coordinate in the transformed graph (y = x-13) actually decreased by 13 units as compared to the original graph of y=x.

Hence the graph actually got translated 13 units in the direction of negative y axis which is option D

As per the translation of a graph, the given graph y= x is translated 13 units  to the right.

"The translation of a graph is its rigid movement, vertically or horizontally."

The given equation of the graph is: y = x.

The equation of the translated graph is: y = x - 13.

We know, the translation of a graph from y = f(x) to y = f(x - a) is translating the graph to the right by 'a' units.

Therefore, the given graph y= x is translated 13 units to the right.

Answer:

She wronged in V1.

Step-by-step explanation:

She write wrongly for the values of length and height. The length of V1 should be 7ft + 4ft which is 11ft and the height is 5ft.

So the volume of V1 is :

V1 = 2ft × 11ft × 5ft

= 110 ft³

Step-by-step explanation:

3*$9.99=$29.97

5*$1.29=$6.45

3 albums would cost $29.97, and 5 individual songs would cost $6.45.

3 albums would cost $29.97, and 5 individual songs would cost $6.45.

For your birthday you get an i‐Tunes gift card. The total cost for you to buy 3 albums at $9.99 each and then 5 individual songs each worth $1.29 is given by the expression 3(9.99) + 5(1.29).

What is Equation?

Two expressions with an equal sign is called as equation.

Through given data we construct equations,

3 albums at $9.99 is given by

3*$9.99=$29.97

5 individual songs each worth $1.29

5*$1.29=$6.45

Total cost for you to buy 3 albums at $9.99 each and then 5 individual songs each worth $1.29 is given by the expression.

3(9.99) + 5(1.29).

Answer:

28

Step-by-step explanation:

Consider the expansion:

[tex]$(x+y)^2=\sum_{k=0}^{n} \binom{n}{k}y^{n-k}x^k$$[/tex]

[tex]$ \binom{n}{k}=\frac{n!}{(n-k)!k!}[/tex]

We have

[tex]$\left(x + y\right)^{8}=\sum_{k=0}^{8} \binom{8}{k} \left(y\right)^{8-k} \left(x\right)^k[/tex]

I'm sorry but I will not write and solve everything, typing LaTeX takes time. But that's the idea:

For [tex]k=0[/tex]

[tex]$\binom{8}{0} \left(y\right)^{8-0} \left(x\right)^{0}=\frac{8!}{(8-0)! 0!}\left(y\right)^{8} \left(x\right)^{0}=y^{8}[/tex]

For [tex]k=2[/tex]

[tex]$\binom{8}{2} \left(y\right)^{8-2} \left(x\right)^{2}=\frac{8!}{(8-2)! 2!}\left(y\right)^{6} \left(x\right)^{2}=28 x^{2} y^{6}[/tex]

[tex](x+y)^8={x}^{8} + 8{x}^{7}y + 28{x}^{6}{y}^{2} + 56{x}^{5}{y}^{3} + 70{x}^{4}{y}^{4} + 56{x}^{3}{y}^{5} + 28{x}^{2}{y}^{6} + 8x{y}^{7} + {y}^{8}[/tex]

Answer:

39.8

Step-by-step explanation:

for this question, use the Pythagorean theorem which is:

a^2 + b^2 = c^3

a = 35

b = 19

c = the answer

lets solve it:

35^2 +19^2 = c^2

solve the exponents first

1225 + 361 = c^2

1586 = c^2

square root both to find c

(the answer is rounded)

39.824 = c

rounded to nearest 10th:

c = 39.8

Answer:

The correct option is:

A) L'' (-4 , -4) , M'' (-1 , -4) , N'' ( -1 , 0) , O'' (-4 , 0)

Step-by-step explanation:

The following are the vertices of a rectangle LMNO

L (-4 , 6)

M (-1 , 6)

N (-1 , 2)

O (-4 , 2)

First we have to reflect it across x-axis

When we reflect a shape across x-axis, the x components of the points remain the same while y components change their signs. After reflection:

L' (-4 , -6)

M' (-1 , -6)

N' ( -1 , -2)

O' (-4 , -2)

After we translate it up by two units, we add +2 to y components of each reflected point.

L'' (-4 , -4)

M'' (-1 , -4)

N'' ( -1 , 0)

O'' (-4 , 0)

Hence, the correct option is A

Answer:

Sine and cosine — a.k.a., sin(θ) and cos(θ) — are functions revealing the shape of a right triangle. Looking out from a vertex with angle θ, sin(θ) is the ratio of the opposite side to the hypotenuse , while cos(θ) is the ratio of the adjacent side to the hypotenuse .

Step-by-step explanation:

Answer:

A.k.a., sin(total), cos(total) are functions that indicate the direction a triangle is right. Speaking from an angle point, sin(f) is an opposite of a hypotenous ratio, while cos(f) is the equivalent to the hypotenuse ratios

Answer:

x = 23/5

y = -2/5

Step-by-step explanation:

We are given two equations

2x + 3y = 8     eq. 1

x - y = 5         eq. 2

From eq. 2

x - y = 5

x = 5 + y       eq. 3

Substitute eq. 3 into eq. 1

2x + 3y = 8     eq. 1

2(5 + y) + 3y = 8

Simplify the equation

10 + 2y + 3y = 8

10 + 5y = 8

5y = 8 - 10

5y = -2

y = -2/5

or

y = -0.4

Substitute the value of y into eq. 3 to get the value of x

x = 5 + y       eq. 3

x = 5 - 2/5

x = 23/5

or

x = 4.6

Therefore, the solution set is

(x, y) = (23/5, -2/5)

This is the point of intersection where these two equations meet.

Answer:

y = 2/3x

Step-by-step explanation:

The first step is to find the slope

Pick two points on the line (0,0) and (3,2)

m = (y2-y1)/(x2-x1)

    = (2-0)/(3-0)

    = 2/3

The y intercept is 0

Using the slope intercept form

y =mx+b  where m is the slope and b is the y intercept

y = 2/3 x +0

y = 2/3x

Answer:

1/3x

Answer:

x = -3   and   y = -4

x + y = -3-4 = -7

Step-by-step explanation:

-4x + 9y = -11 ------------------------------------------------------------------------(1)

-3x + 7y = -9--------------------------------------------------------------------------(2)

multiply through  equation (1) by 3   and multiply through equation(2) by 4

-12x + 27y = -33 -----------------------------------------------------------------------(3)

-12x + 28y   = -36 ----------------------------------------------------------------------(4)

subtract equation (1) from equation (2)

y = -3

substitute y = -3 into equation (2)

-3x + 7(-3) = -9

-3x -21 = -9

add 21 to both-side of the equation

-3x -21 + 21 = -9 + 21

-3x = 12

divide both-side of the equation by -3

-3x/-3 = 12/-3

x = -4

x = -3   and   y = -4
