Answer: choice A) -4
-----------------------------------------------
Step 1) Draw a vertical line through 1 on the x axis
Step 2) Mark the point where the vertical line and the blue curve intersect (or cross each other)
Step 3) Draw a horizontal line through the point marked in step 2. Note how this horizontal line goes through -4 on the y axis.
So the point (1,-4) is on the blue curve. This means if x = 1 is the input then y = -4 is the output. Recall that y = f(x). So f(x) = -4 is the output as well when the input is x = 1.
In short, this is why f(1) = -4
Answer:
{-6}
Step-by-step explanation:
Step 1 Raise both sides of the equation to the index of the radical in the case 2
Step 2 Factor
(x + 6)(x + 6) = 0
x + 6 = 0
x = - 6
Step 3 Check -6
The area of the ground floor after it has been reduced to the nearest tenth is 10,681,800 square foot.
<h3>What is the area of the ground floor?</h3>
In order to determine the area of the ground floor after it has been reduced, the area of the floor has to reduced by 6.3%.
Area that was reduced = 6.3% x 11,400,000 = 718,200
New area = 11,400,000 - 718,200 = 10,681,800 square foot
