Answer:
7.878 ft far
Step-by-step explanation:
Given:
- A ramp is to be lifted to an angle Q = 10 degrees
- The total length of the ramp L = 8 ft
Find:
- how far does the ramp need to be away to hit the edge of the step
Solution:
- The question asks in "other words" the horizontal distance (d) from the ramp pivot on the floor to the edge of the step when it is lifted 10 degrees.
- We will use trigonometry to solve a right angle triangle: The horizontal distance is a projection of Length L on to the flat ground surface. Hence, we have:
cos(Q) = d / L
d = L*cos(Q)
- Plug in values:
d = 8*cos(10)
Answer: d = 7.878 ft
is the equation represented by all the operations.
<u>Step-by-step explanation:</u>
The given function is
It is vertically compressed by a factor of 13 then the function becomes,
It shifted down 6 units, then the function becomes,
It shifted right by 5 units then the function becomes,
Thus the resultant equation thus obtained is
Step-by-step explanation:
time = 2 hours
distance travelled(d) = 124 miles
so
speed = d/t
= 124/2
= 62 miles per hour
Therefore, the speed of car is 62 miles per hour.
Answer:
953..?
Step-by-step explanation:
Answer:
2*(b-6)=8
Explication:
1.divide both sides by 2
b - 6 = 4
2. move the constant to the right and change the sign
b= 4 + 6
3. Calculate
b= 10
