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
240 is 240% of 576
240% x 240 = x
(240 x 240) divide by 100
57,600 divide by 100 = 576
x = 576
question a is 80
question b 20 (is what I could find but not completely sure)
Answer:
Step-by-step explanation:
Slope-intercept form means
where m is given its the slope which is 
and we have the coordinates x and y which is (4, -5) and we need to find the value of c which is the y-intercept so we insert all these values into the equation so ,
now we know the value of slope which is given and we found the value of which is 1 so we put these values into our original slope-intercept form equation
Answer:
3rd option.) 1/8a^12
Step-by-step explanation:
(2a⁴)^-3
=1/(2a⁴)³
=1/8a^12
