20x^4 + 8x^3 + 40x^2
(20x)(20x)(20x)(20x)+(8x)(8x)(8x)+(40)(40)
Answer:
$392. No they don't have enough money to pay for the trip.
They need $255 more dollars, which would take 14 weeks and 2 days.
Step-by-step explanation:
18 x 4 = 72
320 + 72 = 392
647 - 392 = 255
255/18 = 14.2
Diameter = Radius * 2
So radius of the circle is 25/2 = 12.5 feet
Area of a circle is:
A = πr² = 3.14 * 12.5² = 490 sq ft.
Answer:
f(1) = 3
Step-by-step explanation:
f(t) = t² - 1t + 3
we want to find f(1)
all we have to do is replace the t's with 1 and evaluate
f(1) = (1)² - 1(1) + 3
evaluate exponent 1² = 1
f(1) = 1 - 1(1) + 3
multiply
f(1) = 1 - 1 + 3
subtract
f(1) = 3
Answer:
84π sq. units
Step-by-step explanation:
radius of little orange circles = 2
There is a total of 3 little orange circles (1 + 1 + 1/2 + 1/2).
Total area of 3 little orange circles = 3*π*2^2 = 12π
radius of 4 medium white circles = 3
Total of area of 4 medium white circles = 4*π*3^2 = 36π
radius of middle white circle = 6
Area of middle white circle = π*6^2 = 36π
Radius of the big circle = 12
Area of the big circle = π*12^2 = 144π
Area of orange = area of big circle - area of middle white circle - area of 4 medium white circles + area of 3 little orange circles = 144π - 36π - 36π + 12π = 84π
