Answer:
f(x) = 4.35 +3.95·sin(πx/12)
Step-by-step explanation:
For problems of this sort, a sine function is used that is of the form ...
f(x) = A + Bsin(2πx/P)
where A is the average or middle value of the oscillation, B is the one-sided amplitude, P is the period in the same units as x.
It is rare that a tide function has a period (P) of 24 hours, but we'll use that value since the problem statement requires it. The value of A is the middle value of the oscillation, 4.35 ft in this problem. The value of B is the amplitude, given as 8.3 ft -4.35 ft = 3.95 ft. Putting these values into the form gives ...
f(x) = 4.35 + 3.95·sin(2πx/24)
The argument of the sine function can be simplified to πx/12, as in the Answer, above.
ANSWER : -8x + 56
i got it correct on my test
A basket contains 12 apples and some other fruit
40% of the total fruit are apples...so 40% of the total fruit is 12..
0.40x = 12....with x being the total fruit in the basket <== ur equation
x = 12 / 0.40
x = 30....and u have 30 pieces of fruit in the basket
Answer:
12000-14000 (in miles)
Step-by-step explanation:
We are given that the annual cost of driving a certain car is given by the formula
Where m=Represents the number of miles driven per year
C=Cost in dollars
We have to find the range of miles that Jane can drive her new car.
Range of budgets=$7040-$7780
Substitute C=$7040 in the given formula
Substitute C=$7780 in the given formula
The range of miles that Jane can drive her new car=12000-14000
