I feel like there is something missing from this question, for example how large is the tree house? If these are just plain measurements, then I would opt for B.
Answer:
A. 29i
Step-by-step explanation:
Step 1: Plug in given variables
(2 - 5i)(2 + 5i)i
Step 2: Difference of squares (expand)
(4 - 25i²)i
Step 3: Imaginary numbers rules
(4 - 25(-1))i
Step 4: Combine like terms
(4 + 25)i
(29)i
Your final answer will be 29i
Multiply the price by (1 + sales tax).
85 x (1+0.07)
85 x 1.07 = 90.95
He will pay $90.95
Step-by-step explanation/Answer:
<u><em>The value for h(3) is 1.</em></u>
<u><em>Coordinate (3,1)</em></u>
The value on h(3) is located in the last part of the piecewise function, which starts at (1,3) until (4,0). To know the exact image of h(3), we can find the function that belongs to that piece of line, and then calculated the asked value.
So, to calculate the equation, we first have to find the slope with its definition, and then we'll use the point-slope formula to find the equation:
<u><em>Therefore, the coordinates is (3,1), that is, the value for h(3) is 1.</em></u>
