Answer:
False
Step-by-step explanation:
When you multiplying powers will the same base you add the exponent, when dividing you would would subtract the exponents and when raising to a power to a power you would multiply the exponents
Given:
Amplitude = 2
Midline = 5
Period of .
To find:
The cosine function.
Solution:
The general cosine function is:
...(i)
Where, |A| is amplitude, is period, is phase shift and D is the mid line.
Period of function is . So,
Substituting in (i), we get
Therefore, the required cosine function is .
So,
"89 more than" = 89 +
"the quotient of an unknown number and 62" = 62 over x
"is 94" = 94
Multiply both sides by x.
89x + 62 = 94x
Subtract 89x from both sides.
62 = 5x
Divide both sides by 5.
= x
Simplify.
