Evaluate v(x) = 14-3x when x=-3, 0 and 4.

PtichkaEL [24]

Answer:

$v(-3)=23\\v(0)=14\\v(4)=2$

Step-by-step explanation:

$v(x)=14-3x$

$v(-3)=14-3(-3)\\\\v(-3)=14-(-9)\\\\v(-3)=23$

$v(0)=14-3(0)\\\\v(0)=14-0\\\\v(0)=14$

$v(4)=14-3(4)\\\\v(4)=14-12\\\\v(4)=2$

A spherical ball has a diameter of 8 inches. The ball has a slow leak in which the air escapes at the rate of 2.5 inches per sec

s344n2d4d5 [400]

Answer:

107.2 seconds

Step-by-step explanation:

Step one:

given

the diameter of ball 8 inches

radius= 8/2 = 4 in

The volume of the ball

$v=4/3 \pi r^3$

$v= 4/3*3.142*4^3\\\\v= 4/3*3.142*64\\\\v= 804.35/3\\\\v=268.12 in^3$

Step two:

we know that

rate= quantity/time

rate= 2.4 in per second

quantity= 268.12

time=?

time= quantity/rate

time= 268.12/2.5

time= 107.2 seconds

11. What is the value of x in the figure at the right? (Examples 3 and 4)

natka813 [3]

Answer:

x = 11

Step-by-step explanation:

Vertically opposite angles are equal
Angles around a point add up to 360°

Therefore, $15x + 15x + 15 + 15 = 360$

$\implies 30x+30=360$

$\implies 30x=330$

$\implies x=11$
