If the figures below are similar, find the scale factors<br> HELP PLEASE
ExtremeBDS [4]

Answer: 3:2 and 2:3

Step-by-step explanation:

Scale factor is image/preimage.

So from A to B, the image is B and the preimage is A, so the scale factor is 6/4 = 3/2.

Similarly, from B to A, the scale factor is 4/6=2/3

What is the total area of the regions between the curves y = 6x2 − 18x and y = −6x from x = 1 to x=3?.
kvasek [131]

Using integration, it is found that the area between the two curves is of 22 square units.

<h3>What is the area between two curves?</h3>

The area between two curves y = f(x) and y = g(x), in the interval from x = a to x = b, is given by:

A = \int_{x = a}^{x = b} |f(x) - g(x)| dx

In this problem, we have that:

f(x) = 6x^2 - 18x, g(x) = -6x, a = 1, b = 3.

Hence, the area is:

A = \int_{1}^3 |6x^2 - 12x| dx

A = |x^3 - 6x^2|_{x = 1}^{x = 3}

Applying the Fundamental Theorem of Calculus:

A = |3^3 - 54 - 1^3 + 6|

A = 22

The area between the two curves is of 22 square units.

Simplify. 3 ft 23 in.
sleet_krkn [62]

Answer:

4 ft 11 inches

Step-by-step explanation:

Remember that 12 inches is 1 foot, so 24 inches is 2 feet. That means, 23 inches is 1 foot 11 inches. 11/12 is one inch gone from a foot, so 23/24 much be one inch gone from 2 feet.

Since you already have 3 feet, adding the 1 foot and 11 inches leaves you with 4 ft 11 inches as a result.
