Step-by-step explanation:
815 ÷ 4 = 203.75
Answer: 5 cos x
<u>Step-by-step explanation:</u>
y = sin x is y = cos x shifted to the right π/2 units.
y = 5 sin (x + π/2) is a shift to the left π/2 units (which results in cos x) and . an amplitude of 5.
--> y = 5 cos x
a. 3h = -12 + 5s
b. Speed = 51. 6 miles per hour
c. Height = 76 feet
<h3>How to determine the value</h3>
Given the function;
5s - 3h = 12
Where;
- s is the speed in miles per hour
- h is the height in feet
a. To solve for 3h
We have;
- 3h = 12 - 5s
3h = -12 + 5s
b. If the height is 82 feet , then
5s - 3(82) = 12
5s - 246 = 12
collect like terms
5s = 12 + 246
5s = 258
Make 's' the subject
s = 258/ 5
s = 51. 6 miles per hour
c. If the speed is 48 miles per hour, we have;
5(48) - 3h = 12
240 - 3h = 12
collect like terms
-3h = 12 - 240
-3h = -228
Make 'h' the subject
h = -228/ -3
h = 76 feet
Thus, the speed and height are 51. 6 miles per hour and 76 feet respectively.
