Answer:

Step-by-step explanation:
we know that
In this problem we have a exponential function of the form

where
y ----> represent the pool’s loss of water
x ----> the number of days
a is the initial value
a=25,700 gal
b ----> is the base
r=15%=15/100=0.15
b=(1-r)=1-0.15=0.85
The function is equal to

Answer:

Step-by-step explanation:
y = 3x + 14
y = x
.
x = 3x + 14
3x - x = -14
2x = -14

x = -7
.
y = x
y = -7
The car on a Ferris wheel with a radius of 20 feet. travels a distance of 125.6 feet.
In order to determine the distance that the car has travelled, we will use the formula for calculating the circumference of a circle.
<h3>How to calculate Circumference of a circle</h3>
C = 2πr
where
r = radius
Therefore,
r is the radius of the fairy wheel
r = 20 ft
C = 2 × 3.14 × 20
C = 40 × 3.14
C = 125.6 ft
This shows that the car on a Ferris wheel with a radius of 20 feet. travels a distance of 125.6 feet

From the figure, segment QP is in the ray RP and RP contains N and Q in between
so from the options, the two rays will be : ray QP and ray NP
For SU :
segment SU is in the ray RU and RU contains S and T in between,
so from the options again, the two rays will be : ray RU and ray SU
If you would like to write each rate as a unit rate, you can do this using the following steps:
$2 ... 5 cans of a soup
$1 ... x cans of a soup = ?
2 * x = 5 * 1
2 * x = 5
x = 5 / 2
x = 2.5 cans of a soup per $1
$2 ... 5 cans of a soup
$x = ? ... 1 can of a soup
2 * 1 = 5 * x
2 = 5 * x
x = 2 / 5
x = $0.4 per 1 can of a soup
