Answer:
2.95g+9.72f=total cost
Step-by-step explanation:
Answer:
Mean costing = $3,768
Step-by-step explanation:
Given:
Mean A(x) = 260
Rate = $10 per feet
Fixed charge = $1,168
Computation:
Assume;
depth = x ft
So,
Cost of company B = 10x + 1,168
So,
Mean costing = 10A(x) + 1,168
Mean costing = 10(260) + 1,168
Mean costing = 2,600 + 1,168
Mean costing = $3,768
It is 45 because angle EBC is congruent to CDE (x) because of a rule called alternate angles. so x= 45°
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.
