We use the trigonometric function for this case. An escalator is an inclined path. We form a right triangle since we have given the value of the height. The height from the first floor to second floor is called the adjacent while the travelled distance of the people is called the hypothenuse. We use cosine function because we are given in terms of adjacent and hypothenuse. The ratio of cosine function is
cos x = a/h
where x is the angle
Solving for h,
h = a/(cos x) = 21/(cos 30) = 24.25 ft
Answer:
2nd term is 8.
nth term is 3n + 2.
Step-by-step explanation:
nth term = 5 + 3(n - 1)
= 3n + 2
Answer:
-3/2
Step-by-step explanation:
Given two points, we can find the slope by
m = (y2-y1)/(x2-x1)
= (-7 - -1)/ (5-1)
= (-7+1)/(5-1)
= -6/4
= -3/2
Answer:
Expression that can be written in the box on the other side of the equation will be x
Step-by-step explanation:
The left side of equation is:
Simplifying the equation we get:
An equation has no solution when, we cannot find the value of x.
So, The order side of equation can be x
i.e,
So, expression that can be written in the box on the other side of the equation will be x
