Its 15% because you have to divide 270 by 1800
I only know the answer for b I don't know the answer for d. So here is the answer for b 9 time 9= to 18+11+8x4-1=60
Answer:
The distance between these 2 points is 13.
Step-by-step explanation:
Picture the 2 points on a graph as a right triangle, where the hypotenuse of that right triangle is the distance between the points. It is very easy to find the length of the legs of that triangle, and you can use those legs to calculate the length of the hypotenuse.
First, find the vertical distance, or the distance between the y-coordinates. Either just look at a graph and count, or subtract them.

Distance is an absolute value from 0, so -12 is the same as 12.
Next, find the horizontal distance between the x-coordinates.

Now, we have the length of the legs, 5 and 12. Use the pythagorean theorem to find the length of the hypotenuse:

The distance between these 2 points is 13.
Answer:
Factor form of the equation makes it easiest to see the zeros of the function.
Step-by-step explanation:
f(x)=(x−4)(x−6), because you can see when each factor is equal to zero.
Just equate the factor with zero and you will get its zeros.
f(x)=(x−4)(x−6)
Let f(x)= 0
Therefore
(x−4)(x−6) = 0
Therefore
(x−4) = or (x−6)= 0
Therefore, x = 4 or x = 6
Hence, 4 and 6 are the zeros of the given function.
