The period of this Ferris wheel can be calculated as 30 seconds. The amplitude is 25
<h3>How to solve for the period.</h3>a. We have 60 seconds in a minute
In a minute it makes 2 rotations. The period = 60 secs / 2 rotations
= 30 seconds
b. We have h = 25 - 25cos
25 - 25cos
We would have the table in the attachment
d. Amplitude
= max - min / 2
= 50 - 0 / 2
= 25
Answer:
You have to invest $6,250
Step-by-step explanation:
very simple applying the simple interest formula which is
Given data
A, final amount = $10,000
P, initial principal balance= ?
r, annual interest rate = 7.5%
t, time (in years)= 8 years
we can substitute our given data to find the principal needed.
Divide both sides by 1.6 we have
P= $6,250
Answer:
option Bis correct answer.
Step-by-step explanation:
given, a line passes through the point (_1,3)and has slope 2.let another point be x2 and y2.
by the slope formula,
slope (m)=
or , 2=y2_3/x2_(_1)
or, equating with slope we get,
2=y2_3
or, y2=5
again, 2=x2+1
therefore, x2=1
so the points are (1,5)........ans....
