5^4 / 5 = 5^4 * 5^(-1) = 5^(4-1) = 5^3 = 125
Answer:
(5,0) and (5,-2)
Step-by-step explanation:
we know that
If two points are on the line x=5, then the x-coordinates of the points must be equal to 5
therefore
The coordinates of two points that are on the line x=5 are
(5,0) and (5,-2)
The elevation gained after travelling 1.5 miles = 3960 ft.
Step-by-step explanation:
Given data,
Angle of elevation = 30°
Distance traveled= 1.5 miles
1 mile = 5280 ft.
Therefore 1.5 miles = 5280 x 1.5
= 7920 ft.
The height can be calculated by,
sin 30° = height / 7920
1/2 = height / 7920
Height = 7920/2
= 3960 ft.
The elevation gained after travelling 1.5 miles will be 3960 ft.
I don't think you actually have to solve this. I think you just have to write out the equations. It would be:
Mark: 4s + 3c = 26
Brian: 5s + 2c = 29
(x+4)(x-2);
x+4
the LCM is x+4
