Step-by-step explanation:
Area of a rectangle = width times length therefore the equation is 7 times 4 = 28.
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
Answer: 7.7%
Step-by-step explanation: First find the increase in height by subtracting 52 from 56. 56-52=4.
To find what percent this is of 52, divide 4 by 52. 4/52=0.0769. Then convert this from a decimal to a percent by multiplying by 100. 0.0769*100=7.69.
I just rounded it to the nearest tenth, you can change it how you need to.
