It's the 3rd one: y= √(2x-6) + 1

Why?

for x = 3 →→ y =√2(3)-6 +1 →→ y = 1, which verifies your graph

The length of overline CD is 12 units. C^ prime D^ prime is the image of overline CD under a dilation with a scale factor of n.

Rufina [12.5K]

Answer:

A, D , and E

Step-by-step explanation:

We have that:

$\overline{CD} = 12 \: units$

$\overline{C'D'}$

is the image of CD after a dilation of scale factor n.

We use the relation between the image length and object length:

$\overline{C'D'} = n \times \overline{CD}$

Option A

If n=3/2, then

$\overline{C'D'} = \frac{3}{2} \times 12 = 3 \times 6 = 18 \: units$

This is true.

Option B

If n=4, then

$\overline{C'D'} = 4 \times 12 = 36 \: units$

This is false.

Option C

If n=8, then

$\overline{C'D'} = 8 \times 12 = 96 \: units$

This too is false.

Option D

If n=2, then

$\overline{C'D'} = 2 \times 12 = 24 \: units$

This is true

Option E

If n=3/4, then

$\overline{C'D'} = \frac{3}{4} \times 12$

$\overline{C'D'} = 3 \times 3 = 9 \: units$

This is also true.

The drawing plan for an art studio shows a rectangle that is 15.2 inches by 8 inches. The scale in the plan is 4 in.: 5 ft. Find

Kamila [148]

Answer:

Length: 19 feet

Width: 10 feet

Area: 190 feet $x^{2}$

Step-by-step explanation:

This is a question about ratio.

Length: let $x$ be the actual length.

$15.2 : x = 4 : 60$

$x = 19$

Width: let $y$ be the actual width.

$8 : y = 4 : 60$

$y = 10$

Area: A = xy

$19 * 10 = 190$
