The grade is the ratio of rise to run, i.e. the slope aka the tangent.
Answer: (a) 6 degrees
For part b, the road is the hypotenuse c of a right triangle whose tangent of the small angle is 1/10. The height h or rise is the side opposite the small angle.
We could just take the sine of the angle we got but let's get it from the tangent exactly.
Dividing by squared cosine
Answer: (b) Rise of 0.199 km
Answer:
9/4 * 3/4 = 27/16 = 1
Step-by-step explanation:
Answer:
horizontal translation 1 unit right and vertical translation 2 unit up
Step-by-step explanation:
we are given
We can see that in place x , we have x-1
So, it is shifted horizontally right side by 1 unit
We have +2 added to f(x)-value
It means 2 is added to y-value
So, it is shifted vertically upward by 2 units
So, horizontal translation 1 unit right and vertical translation 2 unit up
