Answer:
B) ![\sqrt[4]{80} ^x](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B80%7D%20%5Ex)
Step-by-step explanation:
The given expression is ![80^{\frac{1}{4} x}](https://tex.z-dn.net/?f=80%5E%7B%5Cfrac%7B1%7D%7B4%7D%20x%7D)
It is 4th root. because 1/4 represents the 4th root.
So, ![\sqrt[4]{80} ^x](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B80%7D%20%5Ex)
Therefore, the answer is B) ![\sqrt[4]{80} ^x](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B80%7D%20%5Ex)
Answer: a. 1759.52 radians/minutes
b. 1407.62 feet/minutes
Step-by-step explanation:
Diameter = 1.6 feet
Radius = Diameter/2= 1.6/2 = 0.8 feet
N = 280 revolution
a. Angular speed(w) = 2πN
= 2π × 280
= 560π
= 560 × 3.142
= 1759.52 radians/minutes
Speed of cyclist = wr
= 1759.52 × 0.8
= 1407.62 feet/minutes
Answer:
Yep, im pretty sure everything is good, good job!
Step-by-step explanation:
The answer to angle one is 92
Answer:
26/3 or 8.67
Step-by-step explanation:
Arc lengths are congruent and the radii are the same implies angle at the centre is also equal,
Hence length of the chords are equal too
4x+2 = x+7
3x = 5
x = 5/3 or 1.67
Length of QR = 4x+2
= 4(5/3) +2
= 20/3 + 2
= 26/3 = 8.67
