Answer:
-5/2
Step-by-step explanation:
Use slope formula:
Given 2 points (x1, y1) and (x2, y2) Slope is
y2-y1/x2-x1
The x intercept is 2, the point would be (2,0)
The y intercept is 5, the point would be (0,5)
So you can do (5-0)/(0-2) which is 5/-2 which then would be -5/2
8 4/100 = 8.04, as the ".00" is out of 1.00.
4/10 = 0.40
4 7/100 = 4.07
6/10 = 0.60
8 3/100 = 8.03
8/10 = 0.80
4/100 = 0.04
10 14/100 = 10.14
The quick way to determine what the decimal is, is to divide 100 by the denominator. That way, each time the numerator goes up, you can multiply how many times it goes up by the denominator.
I hope this helps!


An airplane is flying at a height of 5 kilometers above the ground. The distance along the ground from the airplane to the airport is 7 kilometers. What is the angle of depression from the airplane to the airport? (Write the answer to the nearest degree.)


✞ Step 1 ✞: Identify what is asked in the problem.
❒ The angle of depression from the airplane to the airport.
✞ Step 2 ✞: Use appropriate trigonometric ratio to solve the problem.
❒ Since the two legs of the right triangle are part of the problem, hence we use tangent ratio:

✞ Step 3 ✞: Solution and interpretation.





Hence, the angle of depression from the airplane to the airport is approximately 36°.


Answer:
4(x+2) / 5(x-1)
Step-by-step explanation:
We have given two expressions.
2x / x-1 expression I
5x / 2x+4 expression II
we have to find the quotient of expression I and expression II.
(2x / x-1 ) ÷ (5x / 2x+4)
Applying following rule:
a ÷ b = a× 1/b
(2x/x-1)×( 2x+4 / 5x)
(2x)(2x+4) / (x-1)(5x)
(2)(2)(x+2) / (x-1)(5)
4(x+2) / 5(x-1) which is the answer of given question.
