Answer: x = ± 1.68
Step-by-step explanation:
7x^4 = 56
x^4 = 56/7
x^4 = 8
Let a = x²
(x²)² = 8
(a)² = 8
a = ± √8
Now,
a = -√8
x² = -√8 has no real solution.
Taking +√8
a = √8
x² = √8
x = ± √(√8))
x = ± 1.68
Answer:
y²-6
Step-by-step explanation:
(2y-y)(y-6)
= y*(y-6)
= y²-6

At that rate, cyclists will cover a distance of 57 meters in 3 seconds.
The ratio of two related quantities expressed in several units is known as a rate.
Speed is the ratio of the distance traveled in a period of time. Speed is given by:
Speed = distance/time
The cyclist's speed, given that he completes 380 meters in 20 seconds, will be:
Speed = distance/time
s = d/t
v = 380 m / 20 s
v = 19 m/s
If he travels at this rate, at 3 seconds, the distance is:
Speed = distance/time
Distance = Speed × time
d = s × t
d = 19 m/s × 3 s
d = 57 m
Therefore,
At that rate, the cyclist will travel a total distance of 57 meters in 3 seconds.
