What is the area of the composite figure

Mathematics
1 answer:
oksano4ka [1.4K]3 years ago

Answer:

C

Step-by-step explanation:

To find the area of a composite figure, separate it into the regular parts which make the irregular shape. This shape is composed of a semi-circle and a rectangle. Find the area by finding the area of each shape.

Semi-circle:

The semi-circle has a diameter of 2 + 4 + 2 = 8. The area this figure uses the radius which is half the diameter. The radius is 4. To find the area substitute r = 4 into \pi r^2 = \pi 4^2 = 16\pi. However the semi-circle has a smaller circle cut out of it with radius 2. The area of the smaller circle is \pir^2 = \pi 2^2=4\pi. The semi circle in the shape is the areas subtracted which equals 12π.

Rectangle:

The area of the rectangle is found using A = b*h = 2*5 = 10.

The total area is 12π + 10 meters squared.

Factor completely 16x8 − 1.
marta [7]

<u>Given</u>:

The given expression is 16 x^{8}-1

We need to determine the factor of the given expression.

<u>Factor</u>:

Let us rewrite the given expression.

Thus, we have;

\left(4 x^{4}\right)^{2}-1^{2}

Since, the above expression is of the form a^2-b^2, let us apply the identity a^2-b^2=(a+b)(a-b)

Thus, we have;

\left(4 x^{4}+1\right)\left(4 x^{4}-1\right) ------ (1)

Now, we shall factor the term 4x^4-1

4x^4-1=(2x^2)^2-1^2

           =(2x^2+1)(2x^2-1)

Substituting the above expression in equation (1), we have;

\left(4 x^{4}+1\right)\left(2 x^{2}+1\right)(2x^2-1)

Therefore, the factor of the given expression is \left(4 x^{4}+1\right)\left(2 x^{2}+1\right)(2x^2-1)

Hence, Option B is the correct answer.

A​ town's population increases in one year from 50,000 to 58,000. If the population is growing​ linearly, at a steady​ rate, the
jolli1 [7]

Answer:

66,000

Step-by-step explanation:

If a relation is linear, then for equal changes in x there are equal changes in y. If in 1 year the population increases by 8,000, then in any 1-year period, the population will also increase 8,000. The population started at 50,000. In 1 year, it became 50,000 + 8,000 = 58,000. At the end of the second year, it will have increased by another 8,000. 58,000 + 8,000 = 66,000.
