Mon:

225 - (225*0.12) -9 = 189.0

Tue

260 - (260*0.12) -9 = 219.9

Wed

230 - (230*0.12)-9 = 193.4

Thu

180 - (180*0.12) - 9 = 149.4

Fri

150 - (150*0.12) -9 = 123.0

Total:

189+219.9+193.4+149.4+123 = 874.6

A cylinder-shaped drainage pipe 66 in. long measures 25.12 in. around.

Darina [25.2K]

V=hpir^2

tricky, they didn't give us radius
they just gave circiufmerece

c=2pir
25.12=2pir
divide by 2 both sides
12.56=pir
divide by 3.14 both sides
4=r

subsitutet

v=hpir^2
v=66pi4^2
v=66pi16
v=1056pi
v=3315.84 cubic inches

Answer:

The equation that represents the line passing through the point (2, -4) with a slope of one half is

$f(x) = \frac{1}{2}x - 5$

Step-by-step explanation:

The equation of a line can be described by a first order equation in the following format:

$f(x) = ax + b$

In which a is the slope of the line.

Solution:

The line slope is $\frac{1}{2}$ , so $a = \frac{1}{2}$ .

The equation of the line now is:

$f(x) = \frac{1}{2}x + b$

The problem states that the line passes through the point(2,-4). This means that when x = 2, f(x) = -4

So:

$f(x) = \frac{1}{2}x + b$

$-4 = \frac{1}{2}*(2) + b$

$-4 = 1 + b$

$b = -5$

So, the equation that represents the line passing through the point (2, -4) with a slope of one half is

$f(x) = \frac{1}{2}x - 5$
