Using the formula given for area:

Area = 1/2 (7 +5)4 = 1/2(12)4 = 24 square cm.

Now to find the volume multiply the area by the depth:

24 x 6 = 144 cubic cm.

<span>Part A
</span>Chorus:
Expontential growth = b*a^x
b = 15
a = 1.12 (a= r+1), r = 12%

Which gives a function of f(x) = 15*1.12^x

Band
Linear growth = ax+b
a = 2
b = 30

Which gives a function of g(x)=2x+30

<span>Part B:
</span>f(9) = 15*1.12^9 = 41.59
g(9) = 2*9+30 = 48

<span>Part C:
</span>This is probably problem solving, where you're allowed to use calculators and other softwares.

Therefore you can use different softwares, and make f(x) = g(x).

An inlet pipe on a swimming pool can be used to fill the pool in 40 hours. The drain pipe can be used to empty the pool in 42 ho

statuscvo [17]

Answer:

Pool will be filled in 280 hours

Step-by-step explanation:

Inlet pipe fills in 40 hours = 1 pool

Inlet pipe fills in 1 hours = $\frac{1}{40}$

Drain pipe empty in 42 hours = 1 pool

Drain pipe empty in 1 hour = $\frac{1}{42}$

If both pipes are opened together

then in pool fills in 1 hour = $\frac{1}{40}$ - $\frac{1}{42}$

on simplifying the right side ,we get $\frac{42-40}{(40)(42)}$

= $\frac{2}{(40)(42)}$

= $\frac{1}{840}$

$\frac{1}{840}$ pool fills in 1 hour

1 pool will be filled in 840 hours

$\frac{2}{3}$ pool is filled

empty pool = 1 - $\frac{2}{3}$ = $\frac{1}{3}$

therfore $\frac{1}{3}$ pool will be filled in $\frac{1}{3}$ X 840 =

= 280 hours
