Slope intercept is almost the best for everything.
point slope is for when you only know the points on a line
standard form is for when solving systems of equations
Answer:
The height of the tree = 25 feet
Step-by-step explanation:
From the given diagram : EF = 5 feet, FA = 8 feet, CA = 40 feet
∠AFE = 90° and ∠ACB = 90°
To find : CB, the height of the tree.
Solution : In ΔAEF and ΔAB C
∠AFE = ∠ACB = 90°
∠A is common angle.
So, By AA postulate of similarity of triangle, ΔAEF ~ ΔABC
Now, sides of similar triangles are proportional to each other

Hence, The height of the tree = 25 feet
A is the right answer 3+5 is 8 plus 2 is 10. 2+3 is 5 plus 5 is 10
Could be 21. Try replacing function designators with the actual functions.
The tax is 6.5% OF the listed price. "OF" in math means multiply.
First convert the percentage to a decimal
6.5% = .065
Then multiply .065*813.95 = 52.90675. This is the tax.
Simply add the tax onto the cost
813.95 + 52.90675 = $866.86 (rounded)
