Answer:
50.24²
Step-by-step explanation:
Okay, so the formula for the area of a circle is π x radius² and we're just going to use 3.14 for π so:
We first have to find the radius, the radius is half the diameter:
8 ÷ 2 = 4
So 4 is our radius
4² = 16
3.14 x 16 = 50.24
So, the area of the circle is 50.24²

Write properties of function:
x intercept/zero: t₁ = -1, multiplicity 1; t₂ = 10 , multiplicity 1
vertex form: g (t) = (t - 9/2)² - 121/4
vertex: (9/2, -121/4)
Step-by-step explanation:
Formula for compound interest is given by
Where
A is the amount at the end of the period
P is the principal
R is the rate
n is the period
The interest = A - P
From the question
P = $ 3200
n = 3 years
R = 40%
So we have
A = $ 8780.80
<h3>The amount is
$ 8780.80</h3>
The interest is
$ 8780.80 - $3200
<h3>= $ 5580.80</h3>
Hope this helps you
Answer:
His time would be least likely greater than 27.9 minutes or smaller than 21.5 minutes.
Step-by-step explanation:
With an standard deviation of 3.2 minutes, it is clear that the maximum time taken by Roman to complete his run of 3 miles would be
Average time + standard deviation = 24.7 minutes + 3.2 minutes = 27.9 minutes
The minimum time taken by Roman to complete his run of 3 miles would be
Average time - standard deviation = 24.7 minutes - 3.2 minutes = 21.5 minutes
Hence, his time would be least likely greater than 27.9 minutes or smaller than 21.5 minutes.
The distance covered by the hiker if he traveled a horizontal distance of 120 ft at and angle of 6° will be given by:
cos θ=adjacent/hypotenuse
let the hypotenuse be h, adjacent =120 ft, θ=6°, thus plugging in the values we shall have:
cos 6=120/h
h=120/cos 6
h=120.661 ft
Answer: 120.661 ft
