Answer:

i wanna say 4.16

Step-by-step explanation:

since the total length is 2.6, going from c to where the point would be if it wasn't reflected but rather transformed would be 2.6, doing that again to get to c" would be 2 times, therefore I think it's 4.16

What is the volume of the cylinder

lora16 [44]

Answer:

C: 9076.3 cm^3

Step-by-step explanation:

Use the formula for the volume of a cylinder.

V=πr^2 times h

h=25

Here, I'm assuming 21.5 cm is the diameter, so divide 21.5 cm by 2 to get 10.75 as r.

V=(10.75^2)π times 25

115.5625π times 25

This is about 2889π

This simplifies best to choice C, which is about 9076.3 cm^3

However, if I was wrong about 21.5 cm being the diameter, my answer is wrong. If 21.5 cm is r, choice D is the correct answer. If 21.5 cm is the diameter, C is the answer.

The product of (a + b)(a − b) is a2 − b2. (1 point) Sometimes Always Never

jenyasd209 [6]

ANSWER

$\boxed{Always}$
EXPLANATION

The given product is

$( a - b)(a + b)$

This is always equal to

${a}^{2} - {b}^{2}$

The identity

$( a - b)(a + b) = {a}^{2} - {b}^{2}$

is called difference of two squares.

We can verify this by simply expanding the brackets using the distributive property to obtain,

$( a - b)(a + b) = a(a + b) - b(a + b)$

$( a - b)(a + b) = {a}^{2} + ab - ab- {b}^{2}$

This simplifies to

$( a - b)(a + b) = {a}^{2} - {b}^{2}$

Jacob wants to enlarge a 4 in. By 6 in. Photo so that the longer side will be 14 in. How long will the shorter side be? (MUST SH

OleMash [197]

Answer: 9.3 in.

Step-by-step explanation:

Jacob wants to enlarge the larger side of the photo which is the 6 in. part, to becomes 14 in.

This means that Jacob wants to increase the larger side by a scale factor of:

= Length of enlarged picture / Length of original

= 14 / 6

= 2.33

2.33 is therefore the scale factor.

The shorter side will also increase by this same scale factor:

= 4 * 2.33

= 9.3 in.
