Answer:
perimeter = 40 feet
Step-by-step explanation:
side^2 = 100
side = 10
perimeter = 10 x 4 =40
<span>The find step is to find C which is the vertical shift. This is the average between the maximum and minimum. So its 30+70=100/2= 50. the amplitude (A) take the average of the difference between max. temp. and min. value So 70-30= 40/2= 20, but it becomes -20 because the graph is shifted up 50 degrees and decreases to 30 at 4a.m. Then the period is 2pi/B which is 2pi/24, which equals pi/12. A=-20 B= pi/12 C=50</span>
Number of weeks in a year: 52
Weeks in 7 years: 52 x 7 = 364
Final amount = Initial amount x (1 + interest)^(time period)
Final amount = 10,250 x (1.09)³⁶⁴
Final amount = $4.3 x 10¹⁷
