We need to find an equation in the form
.
To find
, we use the formula:
We'll use the points
and
:
The value of
(the y-intercept) is the value of
when
, which is 25.
So the equation is
(choice A).
Answer:
86000000
Step-by-step explanation:
86000000
Move the decimal point 7 places to the left.
8.6000000*107
Answer:
8.6 x10^7
^So it's 86000000
Since Perimeter is Length+ Width, and there are "two lengths" and "two widths", the formula needed here is p=2l+2w. We have the P, so using that, along with knowing that l is 41ft longer than w;
p = 278 , l = w+41
278 = 2l + 2w
278 = 2(w+41) + 2w
We'll use the DISTRIBUTIVE PROPERTY first: 278 = 2w + 82 + 2w
Then we'll COMBINE LIKE TERMS: 278 = 4w + 82
Next we'll subtract 82 from both sides: 196 = 4w
And finally divide both sides by 4:
49 = w
Since the length is w+41 and we now know the width, we can see what the length is: l = w+41 , l = 49 + 41 , l = 90.
Now that we know the length, we can see what the dimensions of the court are:
Perimeter is 278ft
Width is 49ft
And the Length is 90ft.

Answer:
This means the function touches the x-axis at -1 but does not cross.
Step-by-step explanation:
A polynomial graph has several features we look for to determine the equations.
- The zeros of the function are the x-intercepts. If the x-intercepts touch but do not cross then the intercepts have an even multiplicity like 2, 4, 6, etc. If the x-intercepts cross over then they have an odd multiplicity.
- Vice versa. If I know the zero and multiplicity, I can make an accurate sketch of the functions behavior.
This means the function touches the x-axis at -1 but does not cross.
