Answer:
Step-by-step explanation:
Rising 30 feet for every 400 feet of track is not a very large angle of elevation. We set this up as a right triangle to use right triangle trig to solve for the missing angle. The height is 30 and the hypotenuse is 400. The height is the side opposite the angle in question, and the hypotenuse is the hypotenuse! This is the sin ratio. Setting up the ratio using our info:

When you are looking for a missing angle measure, as we are here, use the 2nd-->sin buttons to find the inverse of sin, which looks like this:

Enter in the fraction 30/400 after the parenthesis and then hit enter to get the angle measure of 4.3 degrees.
Answer:
In step 2, she didn’t use an x and y from the same coordinate pair
Step-by-step explanation:
see the attached figure to better understand the problem
we have the points (5, 1) and (3, 5)
step 1
Find the slope
The formula to calculate the slope between two points is equal to
substitute
step 2
The equation of the line in point slope form is

take the point (3,5)
substitute



step 3

therefore
In step 2, she didn’t use an x and y from the same coordinate pair
I believe the answer is 4
Answer:
Step-by-step explanation:
Population t years after 2000 = 736,000 × 1.0149^t
736,000 × 1.0149^t = 1,000,000
1.0149^t = 1,000,000/736,000 = 125/92
Take log base 1.0149 of both sides
t ≈ 20.7
Population exceeds a million in 2021
