Answer:
Step-by-step explanation:
The formula for continuous compounding is
where A(t) is the amount after all the compounding is done, P is the initial investment, r is the rate as a decimal, and t is the time in years. Filling in our info:
First raise e to the product of that power to get
Multiply those numbers together to get A(t) = $824.36
Answer:
B.
Step-by-step explanation:
The key word product tells us we need to multiply. The key word increase tells use we need to add and the key world is means we need to use an = sign
9x + 4 = 58
9x + 4 - 4 = 58 -4
9x = 54
9x / 9 = 54 / 9
x = 6
So the answer is 6
It the wiper blade (and arm) made a full rotation, 2 circles would be formed.
One small circle with radius
b, and a larger circle with radius
a+b.
The areas of these 2 circles are respectively:
and
120° is 1/3 of a complete angle 360° which form a circle, so the areas formed by the arm of length b, and the arm + the wiper blade (a+b) are:
and
in squared respectively.
the actual wiped area is
(in squared)
Area of the window is 54*24= 1296 (in squared)
thus, the ratio of the wiped area to the whole area of the window is 351.7/1296=0.271
Converted to percentages, this is 27.1%
Answer: 27.1%
multiply the 2 numbers together
100 x 13.145 = $1,314.50
