how to find the volume of each sphere, both in terms of \pi and the nearest tenths for r=3 use 3.14 for \p.

icang [17]

Volume formula of a sphere:
$\frac{4}{3}$ $\pi$ r³

given:
r = 3

V = $\frac{4}{3}$ $\pi$ (3)³
V = $\frac{4}{3}$ × 27 $\pi$
V = 36 $\pi$ units³ (in terms of $\pi$ )
V = 113.097 units³ ≈ 113.1 units³

Use substitution to solve the following system of equations. Show all of your work. Write the solution as an ordered pair.

trapecia [35]

Answer:

$\left \{ {{x=2} \atop {y=2}} \right.$

Step-by-step explanation:

Substitute the second equation into the first one:

$4x+(2x-2)=10\\6x-2=10\\6x=12\\x=2$

Substitute $x=2$ into the second equation:

$y=2\times 2-2\\y=4-2\\y=2$

$\therefore \left \{ {{x=2} \atop {y=2}} \right.$

KN bisects ZJKM. If mZNKJ = 7x-9 and<br> m2JKM = x + 3, find m2JKN.

BaLLatris [955]

Answer:

Step-by-step explanation:

7x - 9 = x + 3

6x - 9 = 3

6x = 12

x = 2

7(2) - 9 + 2 + 3

14 - 9 + 5

5 + 5 = 10

F(3)= 5x^2 - 4x + 9<br> evaluate this quadratic function

Neporo4naja [7]

Answer:

$f(3) = 38$

Step-by-step explanation:

Given the quadratic function

$f\left(x\right)=\:5x^2\:-\:4x\:+\:9$

Evaluating the quadratic function

$f\left(x\right)=\:5x^2\:-\:4x\:+\:9$

substitute x = 3

$f\left(3\right)=\:5\left(3\right)^2\:-\:4\left(4\right)\:+\:9$

$f(3) = 45-16+9$

$f(3) = 38$

Therefore,

$f(3) = 38$
