Answer:

20x^3-14x^2+37x-7

Explanation: We need to simplify the given expression:

(4x^2-2x+7)(5x-1)

Simplification step by step:

4x^2(5x-1)-2x(5x-1)+7(5x-1)4x^2\times5x-4x^2-2x\times5x+2x+7\times5x-720x^3-4x^2-10x^2+2x+35x-7=20x^3-14x^2+37x-7

Therefore this is the simplified expression:

Over a 24-hour period, the tide in a harbor can be modeled by one period of a sinusoidal function. The tide measures 4.35 ft at
netineya [11]

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.
