Given
The coordinates of the points on the path are:
P(20,7), R(-4,-9), O(20, -9), S(-4, -24)
The total length of the path from P to S is:
The distance d between two points can be found using the formula:
The distance between P and R:
The distance between R and O:
The distance between O and S:
y=5
5=1/4x^2+1
4=1/4x^2
16 = x^s
x = square root (16) = 4
x=3
y= 1/4(3)^2+1 = 3 1/4 = 13/4
8 divided by (1/4) = 8*4 = 32 home sites
Answer:
Step-by-step explanation:
The standard form of an equation of a circle:
<em>(h, k)</em><em> - center</em>
<em>r</em><em> - radius</em>
We have the center (8, 6) → h = 8, k = 6,
and endpoints of a radius (8, 6) & (8, 0).
The formula of a distance between two points:
Substitute:
Finally:
answer:
-2x + 9 or -2 which is what the question asks
step-by-step explanation:
- we have to combine like terms which means terms that are similar
- in this, only 5x and -7x are like terms since both have x with them
- 9 will stay the same since it does not have a like term
5x + 9 + (-7x) = __x + 9
-2x + 9
- therefore, -2 goes in the blank
