Step-by-step explanation:
(1)
Calculate the circumference (C) of the wheel
C = πd (d is the diameter )
= 3.14 × 8 = 25.12 cm
Now divide the distance travelled by the circumference.
times rotated = 12560 ÷ 25.12 ≈ 500
----------------------------------------------------------------
(2)
The area (A) of a circle is calculated as
A = πr² ( r is the radius )
Find r by using the circumference (C)
2πr = 50.24 ( divide both sides by 2π )
r = 50.24 ÷ 6.28 = 8 , then
A = 3.14 × 8² = 3.14 × 64 ≈ 200.96 ft² ( student 3 )
-----------------------------------------------------------------
(3)
C = πd = 3.14 × 30 = 94.2 ≈ 94 m
So, we are looking for F of G of 2. So, we need to work backwards and find G(x) first.
So we know that g(-2) = -6, now we take thatt -6 and plug in into f(x)
68 is the answer
It's quadratic
(3x+4)(-2x-3)
expand using FOIL:
-6x^2-14x-12=0
remember -6x^2 term means its quadratic since it's powered by 2
