we know that

An isosceles triangle is a triangle with two equal sides and two equal angles

in this problem we have

AC=AB

∠B=∠C

therefore

Answer: The correct option is (D) It is equal to the measure of angle C.

Step-by-step explanation: Given that ΔABC is an isosceles triangle as shown in the figure. AB = AC.

We are to select the TRUE statement about the measure of ∠B.

We know that the measures of the angles opposite to the equal sides of a triangle are equal.

So, AB = AC implies that

m∠C = ∠B.

Therefore, the measure of angle B is equal to the measure of angle C.

Thus, (D) is the correct option.

Find the focus for y=x^2+4x-7

padilas [110]

ANSWER

$(2,-10.75)$

EXPLANATION

The given function is

$y = {x}^{2} - 4x - 7$

We rewrite this function to obtain,

$(y + 11) = {( x- 2)}^{2}$

We now compare this function to

$(y - k) = 4p {( x- h)}^{2}$

We have

$4p = 1$

This implies that,

$p = \frac{1}{4}$

The vertex is (2,-11).

The focus is

$(2,-11+ \frac{1}{4} )$

$(2,- \frac{43}{4} )$

$(2,-10.75)$

Find the volume of a cylinder with height 14.7 cm and diameter 10.5 cm.

velikii [3]

Hello!

The volume of a cylinder is found by using the formula: V = πr²h.

The problem has given us the height of the cylinder, which is 14.7 centimeters, and the diameter which is 10.5 centimeters. The volume of a cylinder requires the radius, so therefore, to find the radius, divide the diameter by half, and that will give the radius.

R = 10.5 / 2

R = 5.25 centimeters

With that radius and the height, we can find the volume of the cylinder.

V = π(5.25)²(14.7)

V = 27.5625(14.7)π

V = 405.17π, 1272.23 (multiplied by 3.14), 1272.88 (multiplied by π)

Therefore, the volume of this cylinder is 1272.88 centimeters³.
