Answer:
River C: 2,600 miles
River D: 3,000
Step-by-step explanation:
Since beside a 400 mile difference they are the same just subtract 400 and divide it by 2 then add 400 to find river d
Using the 2-point form of the equation for a line, you can write the equation as
y = (y₂ -y₁)/(x₂ -x₁)×(x -x₁) +y₁
If we let (x₁, y₁) = (4, 2) and (x₂, y₂) = (9, 12) this becomes
y = (12 -2)/(9 -4)×(x -4) +2
y = (10/5)×(x -4) +2
y = 2x -6
The equation in slope-intercept form of the given function is ...
y = 2x -6
Answer: C(t) = 28000(0.811)^t
Step-by-step explanation:
it begins to depreciate at a rate of 18.9% annually. This means that the rate at which the value is decreasing is exponential. We would apply the formula for exponential growth which is expressed as
y = b(1 - r)^ t
Where
y represents the value of the car after t years.
t represents the number of years.
b represents the initial value of the car.
r represents rate of depreciation.
From the information given,
P = 28000
r = 18.9% = 18.9/100 = 0.189
Therefore
y = 28000(1 - 0.189)^t
y = 28000(0.811)^t
Where C(t) represents y, the function becomes
C(t) = 28000(0.811)^t
Answer:
B. 100 1/2
Step-by-step explanation:
100 1/3 is = 100.33 which is greater than 100.25 which is the halfway point from 100 to 100 1/2. Since 100.33 is closer to 100 1/2 than 100, we can round up to 100 1/2 because that is the nearest 1/2.
