Flat rate=y intercept
rate per mile=slope
y=3x+10 would be it
1.
3 is the value of the slope (3 dollars per mile)
2.
y intercept is (0,10)
3.
22 miles
y=3(22)+10
y=66+10
y=76
$76
Answer:
Maximum area possible
f(max) = 3906,25 ft²
Dimensions:
a = 62,5 ft
w = 62,5 ft
Step-by-step explanation:
Perimeter of the rectangular fencing P = 250 feet
And sides of the rectangle a and w (width of rectangle)
Then
A = a*w
2a + 2w = 250 ⇒ a = (250 -2w)/ 2 ⇒ a = 125 - w
f(w) = (125 - w ) *w f(w) = 125w - w²
Taking derivatives both sides of the equation
f´(w) = 125 - 2w f´(w) = 0 125 - 2w = 0
w = 125/2
w = 62,5 ft ⇒ a = 125 - 62,5
a = 62,5 ft
f(max) = ( 62,5)²
f(max) = 3906,25 ft²
Jeremy will pay $41.05 interest.
We know that, Interest = PRT/100
where,
P = principal
R = rate
T = time
For given question, principal (P) = $325.18
interest rate R = 12 5/8%
= 12.625%
And period T = 1 year
We need to find the interest.
⇒ Interest = PRT/100
⇒ Interest = (325.18 × 12.625 × 1) / 100
⇒ Interest = 4105.3975 / 100
⇒ Interest = $41.05
Therefore, Jeremy will pay $41.05 interest.
