Remark
I'm not sure I know what you mean, but I will answer trying to interpret it so it fits the description of the question.
Step One: Set up the equation. The normal way of solving this would be to use the Cos function.
Cos(theta) = Adjacent / hypotenuse = x/8 Multiply both sides by 8
8*cos(theta) = x Theta = 35
8*cos(35) = x This is about as simple a way as is possible.
6.553 = the height of the sale.
Step Three: try using the reciprocal
1 / cos(35)= hypotenuse / adjacent
1/0.8191 = 8/x cross multiply
x = 0.8191 * 8
x = 6.553
Answer:
The answer is the 3rd one, x is shifted left 6 units and up 2 units.
Step-by-step explanation:
-6 in graphs or coordinate planes, is moving to the left, or moving down. +2 in graphs or coordinate planes can mean moving up, or moving to the right. So the 3rd one is your answer.
Step-by-step explanation:
Suppose that the weight (in pounds) of an airplane is a linear function of the amount of fuel (in gallons) in its tank. When carrying 15 gallons of fuel, the airplane weighs 2187 pounds. When carrying 35 gallons of fuel, it weighs 2303 pounds. How much does the airplane weigh if it is carrying 50 gallons of fuel?
----
You have two points relating fuel and weight.
(15,2187) and (35,2303)
------------
slope = (2303-2187)/(35-15) = 5.8
----
intercept = ?
2187 = 5.8*15 + b
b = 2100
-------
Equation:
f(x) = 5.8x + 2100
---
f(50) = 2390 lbs.
