I believe the answer is 75 I am not sure but I adds up because 4*.75 equals to 3 there is another way to solve this though we can do the is over of equals % over 100 then we still get three have a nice day and good luck on your assignment (:
Answer:$8.36
Step-by-step explanation:
Change % to decimal and multiply
15% =.15
55.73 x .15 = 8.3595
To find the area between the x-axis and the parabolic curve, take the integral of the area in which the curve is above the x-axis.
function of the graph is
y = 4x - x²
We can tell by the function (specifically -x²) that the parabola will point downward.
To find the domain in which y>0, let's find the roots (0's) of the function:
0 = 4x - x²
0 = x (4 - x)
x = 0 or x = 4
Between x=0 and x=4, the curve is above the x-axis. To find the area of the graph, let's take the integral on this range:
First, take the antiderivative of 4x - x²:
2x² - (1/3) x³
Then, plug x=4 into the anti-derivative, and subtract the anti-derivative at x=0:
2(4)² - (1/3)(4³) - (0 - 0)
32 - 64/3
96/3 - 64/3 = 32/3
Closest Answer is C) 10
The solution to the system of equation is x ≤ –4 and x > 4
<h3>Compound inequality</h3>
Given the inequality expression
2x ≤ –8 or 3x + 1 > 13
Solving individually
2x ≤ –8
Divide both sides by 2
2x/2 ≤ –8/2
x ≤ –4
For inequality 3x + 1 > 13
3x > 13 - 1
3x > 12
x > 12/3
x > 4
Hence the solution to the system of equation is x ≤ –4 and x > 4

Answer:
D. -10, 10
Step-by-step explanation:
Instead of inserting values into x to solve, let's isolate x.
In order to do this, we must take the square root of both sides.
To find the square root of 100, we must figure out what = 100 when multiplied by itself. Reminder, it can be both a positive or a negative square root, as positive times positive is a positive, and negative times negative is a positive.
The square root of 100 is -10 or 10, as 10 x 10 or -10 x -10 = 100.
