The area of 1963.46 square inches covered by the motion of the blades when turned on.

Step-by-step explanation:

The given is,

The arm of a ceiling fan measures length of 25 inches.

Step:1

When the fan turned on it makes a rotation of blades. It is in the circular form.

Formula to calculate the area of circle,

$A= \pi r^{2}$ ...................................(1)

Where, r - Radius of circle

From the given values,

Length of fan arm = r = 25 inches

Equation (1) becomes,

$=\pi (25)^{2}$

$=\pi (625)$

$=(\frac{22}{7} )(625)$

= 1963.49

= 1963.49 square inches

Area covered by fan = 1963.49 square inches

Result:

The area of 1963.46 square inches covered by the motion of the blades when turned on.

Which situations represent a y-intercept of 2? Select all that apply.

Anastaziya [24]

I am not 100% sure but I believe its,
(0,2)
Ball thrown from an initial height of two feet
Jeremy's change jar that started with a $2 deposit

I chose these because the Y always represents the starting point of whatever the problem is about, then the X represents the progress its made since the beginning. So if it doesn't say start or initial or any words like that its probably not the Y, its the X.

frutty [35]

The answer is: APR = 10.56%

Explanation: Using an excel spreadsheet and the RATE function, we can calculate the monthly interest rate of buying the car:

=RATE(72,-489,25995)

= 0.8803% monthly interest rate

Then we multiply the monthly interest rate by twelve to get the APR:

APR = 0.8803% x 12 = 10.56%

The revenue of Apple® went from $54.5 billion in 2013 to $74.6 billion1 in 2015. Find an exponential function to model the reven

Rus_ich [418]

r = continuous growth rate

revenue t years after 2013 = 54.5×10⁹×e^(rt)

74.6×10⁹ = 54.5×10⁹×e^(2r)

e^(2r) = 74.6/54.5

2r = ln(74.6/54.5)

r = ½ln(74.6/54.5) ≅ 0.15697 = 15.697% per year

Hope this helps!

Lauren would like to find the midpoint of a line segment that has endpoints at (–0.5, 3) and (4, 7.5). Which statements are true

Bond [772]

Answer:

Lauren could solve 7.5 + 3 / 2 to find the y-intercept.

Lauren could solve (1/2)(4+0.5) to find the x-intercept.

Finding the midpoint is equivalent to partitioning a line segment a 1:1 ratio.

Henri has $24,000 invested in stocks and bonds. The amount in stocks is $6,000 more than three times the amount in bonds. Call t

makvit [3.9K]

Answer:

The solve of that problem is that Hernry invested $18.000 in stocks and $6.000 in bonds.

Step-by-step explanation:

First, to explain you have to do a multiplication about 6 on three. Like three times more than bonds, the result is 18. Then you have to do a subtraction on $24.000 less $18.000, and the result is $6.000, so six is the amount on bonds. And is three times less than stocks, like the questions ask.
