Answer:
$ 9
Step-by-step explanation:
Simple Interest = P.R.T / 100
P = Principal (Amount invested) =$30
R = Rate= 10%
T = Time = 3 years
Therefore, Simple Interest (I):
I = PRT/100
I = ($30 * 10 * 3 ) / 100
I = $900 / 100
I = $9
She will have a total of $9 in three years
Answer:
18
Step-by-step explanation:
50 - 32 = 18
Answer:
Step-by-step explanation:
Use the form a sin ( bx- c) + d to find the variables used to find the amplitude, period, phase shift, and vertical shift.
a = 3
b = 2
c = 0
d = 0
Find the amplitude | a |
Amplitude: 3
Find the period using the formula 2π ÷ IbI
Period: π
Find the phase shift using the formula 
Phase Shift: 0
Find the vertical shift : d
Vertical Shift: 0
