Harold wrote this equation to model the level of water in a pool over time. The variable x represents time in hours. f(x) = 3,50

lina2011 [118]

Answer:

The water level is falling.

The initial level of water in the pool was 3,500 units

The water was 2,600 units high after 4 hours.

Step-by-step explanation:

The given function that models the water level is

$f(x)=3,500-225x$

where $x$ represents time in hours.

The function represents a straight line that has slope $m=-225$

Since the slope is negative, it means the water level is falling.

The initial level of water in the pool can found when we put $x=0$ into the function.

$f(0)=3,500-225(0)$

$f(0)=3,500$ , hence the initial level is 3,500.

To determine the level of water in the pool after 14 hours, we put $x=14$ into the equation to get;

$f(14)=3,500-225(14)$

$f(14)=3,500-3150$

$f(14)=350$

To determine the water level after 4 hours we put $x=4$

$f(4)=3,500-225(4)$

$f(4)=3,500-900$

$f(14)=2,600$

Answer: 15.2

Step-by-step explanation:

(14)^2 + (6)^2 = c^2

196 + 36 = c^2

232 = c^2

Square root both sides

15.231546 = c

15.2 ≈ c

If each soda sells for $2.50, what is the expected daily total dollar amount taken in by the vendor from the sale of sodas?

Mariana [72]

Answer:

$34.38

Step-by-step explanation:

Y: A random variable that indicates the amount of money that the seller will receive.

p=2,50$

if x=0 → y=0.2,50=0$

if x=5 → y=5.2,50 = 12,5 $

if x=10 → y=10.2,50= 25$

if x=15 → y=15.2,50= 37,5$

if x=20 → y=20.2,50= 50 $

if x=25 → y=25.2,50= 62,5$

Y= { 0$ ; 12,5$ ; 25$ ; 37,5$ ; 50$ ; 62,5$ }

E(Y)= ∑Y.P(Y)

= 0.P(0)+12,5.P(12,5)+ 25.P(25)+ 37,5.P(37,5)+ 50.P(50)+ 62,5.P(62,5)

= 0.0,01+ 12,5.0,15+ 25.0,25+ 37,5.0,3+ 50.0,25+ 62,5.0,04

= 0 + 1,875 + 6,25 + 11,25 + 12,5 + 2,5

= 34,38$ expected value of the amount of money the seller receives.
