Answer:

D. 3

Step-by-step explanation:

For g(x) = |x|, we seem to have ...

f(x) = 3|x| = 3g(x) = a·g(x)

The value of 'a' is 3.

A number y is rounded to 2 decimal places

Yakvenalex [24]

Y can be rounded up to 1.51 from a minimum value of 1.505
This is the lower bound.

y can be rounded down to 1.51 from a maximum value of 1.515
this is the upper bound.

y is between the lower bound and the upper bound so y is between 1.505 and 1.515

This is shown as 1.595<=y<1.515

<= is the typed out version of (greater than/equal to) which is < with a line under it.

Which of the following is a true polynomial identity

zhuklara [117]

Answer:

It's a.

Step-by-step explanation:

(a - 2b)^2 + 8ab

= a^2 - 4ab + 4b^2 + 8ab

= a^2 + 4ab + 4b^2.

((a + 2b)^2 = a^2 + 4ab + 4b^2.

What is the volume of this cone?

olchik [2.2K]

Answer:

The volume of the cone is approximately 453.0 cm³

Step-by-step explanation:

The volume of a cone is one third that of a cylinder with the same height and radius. That gives us 1/3 πr²h, where r is radius and h is height.

However, we are not given the height of the cone, but the side length. We can work out the height using the Pythagorean theorem, as we have a right triangle with the height, base radius, and length. You may recall that the Pythagorean theorem states that the square of the hypotenuse of a right triangle is equal to the sum of the squares of it's other two sides:

$a^2 = b^2 + c^2$

So we can find the height of the cone with that:

$10.8^2 = 7.4^2 + h^2\\h^2 = 10.8^2 - 7.4^2\\h^2 = 116.64 - 54.76\\h^2 = 61.88\\h = \sqrt{61.88}\\h \approx 7.9$

Now that we have the cone's height, we can solve for its volume:

$v = \frac{1}{3} \pi r^2 h\\v = \frac{1}{3} \pi \times 7.4^2 \times 7.9\\v = \frac{1}{3} \pi \times 54.76 \times 7.9\\v = \frac{1}{3} \pi \times 432.6\\v = \pi \times 144.2\\v \approx 453.0 cm^3$
