Answer-18.25 inches

Answer:

18.25 inches

Step-by-step explanation:

We need to calculate how many inches we cut off. Knowing that, we subtract that amount to the total length of the rope and we have the length of what remain.

We cut 6 pieces of 18.5 inches long each. The total of inches that we cut off is 6*18.5 = 111 inches.

Now we subtract 111 inches to the original length of the rope:

129.25 - 111 = 18.25  inches

The rope is 18.25 inches long after we cut off the 6 pieces.

The price of an item selling at 150% of its $63 value is
Triss [41]
You just have to multiply the percentage by the amount:
(150/100)×$63 
1.5×$63= $94.50
If you aren't allowed a calculator, then just find half of $63 (the 0.5 of the fraction) and add it to $63 (the 1. of the fraction).
$63÷2= $31.5
$63+$31.5= $94.50

What is the distance between the points (-6,5) and (8,-2) on a coordinate plane?
Naddik [55]

Distance Formula: D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2

Apply the points: D=\sqrt{(8-(-6))^2+((-2)-5)^2

Solve: D=\sqrt{(8-(-6))^2+((-2)-5)^2}\\D=\sqrt{14^2+(-7)^2}\\D=\sqrt{169+49}\\D=\sqrt{218}

Since the square root of 218 cannot be simplified, the answer is

D=\sqrt{218}

Explain why the function of f(x)=4x^2+8x is neither even or odd
myrzilka [38]

Answer:

By putting x = -x in f(x) i.e. f(-x) we didn't get f(x) or -f(x) so, the function is neither even nor odd.

Step-by-step explanation:

We need to explain why the function of f(x)=4x^2+8x is neither even or odd

First we will understand, when the function is even and odd

Even function:

<em>A function is even if f(-x) = f(x) </em>

Odd function:

<em>A function is odd if f(-x) = -f(x) </em>

So, if we get the above result by putting x = -x, then we can say that the function is even or odd.

If we don't get any of the above results then the function is neither even nor odd.

So, for the given function: f(x)=4x^2+8x

Put x = -x

f(x)=4x^2+8x\\Put x=-x\\f(-x)=4(-x)^2+8(-x)\\f(-x)=4x^2-8x

So, by putting x=-x in f(x) i.e. f(-x) we didn't get f(x) or -f(x) so, the function is neither even nor odd.
