60km = 37.2823
I don't know how many decimal places you are required to round but that is the precise answer.
Answer: The slope is -32
Explanation:
Start with the slope formula:
m= (y2 - y1) / (x2 - x1)
Substitute point values in the formula
m = (-25 - 7) / (85 - 84)
Simplify each side of the equation
m= (-25 - 7) / (85 - 84) = -32/1
Solve for slope (m)
m= -32
The area of a trapezoid = (a + b)/2 x h
Where a and b are the lengths of the parallel sides and h is the perpendicular distance between them.
When (a + b)/2 x 6 = 30
then (a + b)/2 = 5
a + b = 10
Possible values for (a,b) are (4,6) (3,7) (2,8) (1,9) assuming a < b but (7,3) is also valid.
Any positive real value is possible so (4.8, 5.2) and (0.3, 9.7) are valid
In general {a,b both real: 0
I believe the answer would be 2xyz9x2yz18x2 - 6y4x3 + 5ab - 4. the x canceled itself out.
The rate of change of the plane's altitude is 2250 feet per minute.
<h3>How to calculate the rate?</h3>
The rate of change of the plane's altitude will be:
= (35000 - 17000)/8
= 18000/8
= 2250 feet per minute.
When graphing the descent of the plane, the starting value for its altitude be 35000 feet.
The linear function will be:
y = mx + b
35000 = 2250x + b
35000 = 2250(0) + b
b = 35000
y = -2250x + 35000
The information given in this problem that did not need to write an equation for the descent is the initial details about how long that the plane travelled.
