Step-by-step explanation:

To find out y intercept of any function, we plug in 0 for x and solve for y

For any function y=ab^x + c

The horizontal asymptote at y=c

Now we check each function

$f(x)= 7^x -4$

Plug in 0 for x to find y intercept

$f(0) = 7^0 -4 = 1 -4 = -3$

y intercept at (0,-3)

Horizontal asymptote at y=c , here c= -4

So horizontal asymptote at y = -4 and y intercept at (0,-3)

$f(x)= 3^{x+2} +4$

Plug in 0 for x to find y intercept

$f(0) = 3^{0+2}+4 = 9+4= 13$

y intercept at (0,13)

Horizontal asymptote at y=c , here c= 4

So horizontal asymptote at y = 4 and y intercept at (0,13)

$f(x)= 9^{x+1} -4$

Plug in 0 for x to find y intercept

$f(0) = 9^{0+1}-4 = 9-4= 5$

y intercept at (0,5)

Horizontal asymptote at y=c , here c=-4

So horizontal asymptote at y = -4 and y intercept at (0,5)

$f(x)= 2^x+4$

Plug in 0 for x to find y intercept

$f(0)=2^0+4=5$

y intercept at (0,5)

Horizontal asymptote at y=c , here c= 4

So horizontal asymptote at y = 4 and y intercept at (0,5)

Margo wants new carpet and a new wallpaper border for her bedroom. The room is 5.7 yards long and 6 7 8 yards wide. About how ma

Lelu [443]

Answer:

39.19 yards^2

25.15 yards

Step-by-step explanation:

To determine the squares square yards of carpet needed, we have to determine the area of the room

The room is shaped like a rectangle

area of a rectangle = length x breadth

5.7 x 6 7/8

To multiply, convert 6 7/8 to a decimal

to do this, divide 7 by 8. Add the value gotten to 6

5.7 x 6.875 =39.19 yards^2

To determine the yards needed for the border, calculate the perimeter of the room

Perimeter = 2 x (length + breadth)

2 x(5.7 + 6.875) = 25.15 yards

The data below shows average number of text messages a group of students send per day. What is a histogram that represents the d

OLga [1]

Answer:

The graph is attached.

Step-by-step explanation:

The range of this data is the highest value, 22, subtracted by the lowest value, 1: 22-1 = 21.

Using boundaries, the first bar would go from 0.5-3.5; the second from 3.5-6.5; the third from 6.5-9.5; the fourth from 9.5-12.5; the fifth from 12.5-15.5; the sixth from 15.5-18.5; the seventh from 18.5-21.5; and the eighth from 21.5-24.5.

The frequency of the first bar, its height, would be 1; the height of the second bar is 2; the height of the third bar is 3; the height of the fourth bar is 2; the height of the fifth bar is 3; the height of the sixth bar is 1; the height of the seventh bar is 1; and the height of the eighth bar is 1.
