Answer:
Domain: x>=1
Step-by-step explanation:
what values of x make it work (square roots must be greater than or equal to zero)
sqrt (5x-5) >=0
square each side
5x-5 >=0
add 5 to each side
5x>=5
divide by 5 on each side
5x/5 >=5/5
x >=1
Direct variation should be called linear variation.
In this case, the answer is B.
A has the quadratic variation, C has the inverse variation, D has the cubic variation
The answer is 71°.
x = angle
3x = 90 - x - 14
4x - 76
x = 19°
90 - x = 71°
(X-7)(x-1)
Minimal x values=7,1
Not the same x value
7 is the greater minimal value
Answer:
20 m
Step-by-step explanation:
the distance from the top car to the bottom car is equal to the diameter of the wheel. The diameter is 40 m, and that is twice the radius. The radius of the Ferris wheel is (40 m)/2 = 20 m.
