A photo of a painting measures 13 inches by 17 inches. The scale factor is 1/3. What size is the painting?

1 answer:

4 0

Size of the painting: A * B

Scale factor: 1/3

Size of the photo: [1/3]A * [1/3]B

[1/3]A = 13inches => A = 13inches * 3 = 39 inches

[1/3]B = 17 inches => B = 17 inces * 3 = 51 inches.

Answer: the size of the painting is 39 inches by 51 inches.

Which values are within the range of the piecewise-defined function?

musickatia [10]

Answer: y < 1

Step-by-step explanation:

$\begin{array}{c|c||l}\underline{x; x-3}&\underline{y=-x-2}&\\-3&-(-3)-2=1&\text{approaching but not including 1}\\-2&-(-2)-2=0&\\-1&-(-1)-2=-1&\end{array}$

The first function has the range of y < -4

The second function has the range of y = -3

The third function has the range of y < 1

The largest y-value is 1 and the smallest y-value is -∞, therefore the range (y-values) are from -∞ to 1 → y < 1

Find formula for exponential function passing through points (-3,3/8) and (2/12)

Alex17521 [72]

Answer:

y = 3 · 2ˣ

Step-by-step explanation:

Exponential function is:

y = abˣ

Plug in the points:

⅜ = ab⁻³

12 = ab²

Solve the system of equations. Start by dividing the second equation by the first:

12 / ⅜ = (ab²) / (ab⁻³)

32 = b⁵

b = 2

Plug into either equation to find a:

a = 3

Therefore:

y = 3 · 2ˣ
