Answer:

x = 7

Step-by-step explanation:

Set the equations equal to each other, since the two angles are congruent.

x + 16 = 4x - 5 now solve

21 = 3x

x = 7

How do you illustrate quadratic equation in one varible?<br>

kvasek [131]

Answer:

A quadratic equation is an equation of the second degree, meaning it contains at least one term that is squared. The standard form is ax² + bx + c = 0 with a, b, and c being constants, or numerical coefficients, and x is an unknown variable. One absolute rule is that the first constant "a" cannot be a zero.

Find the distance between the points (2,4) and (9,10).

evablogger [386]

Answer: d = 9.219544 this is kinda exact haha

Step-by-step explanation:

For:

(X1, Y1) = (2, 4)

(X2, Y2) = (9, 10)

Distance Equation Solution:

=(9−2)2+(10−4)2‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾√

=(7)2+(6)2‾‾‾‾‾‾‾‾‾‾√

=49+36‾‾‾‾‾‾‾√

=8‾√5

=9.219544

Find the volume of a hemisphere that has a diameter of 48 inches and leave your answer in terms of pie

marin [14]

<u>Given</u>:

Given that the diameter of the hemisphere is 48 inches.

We need to determine the volume of the hemisphere.

<u>Radius:</u>

The radius of the hemisphere can be determined using the formula,

$r=\frac{d}{2}$

Substituting d = 48, we get;

$r=\frac{48}{2}$

$r=24$

Thus, the radius of the hemisphere is 24 inches.

<u>Volume of the hemisphere:</u>

The volume of the hemisphere can be determined using the formula,

$V=\frac{2}{3} \pi r^3$

Substituting r = 24, we get;

$V=\frac{2}{3} \pi (24)^3$

$V=\frac{2}{3} \pi (13824)$

$V=9216 \pi \ in^3$

Thus, the volume of the hemisphere is 9216π cubic inches.
