Answer:
Option C.
Step-by-step explanation:
You can find this by doing ratios. 1/1.1266=x/700. Then, solve for x and you will get 621.3385.
The equation of a line is y = mx + b
We know there is a b because the y intercept is not zero, so the first choice is wrong. We also know the last choice is wrong because this problem definitely has a slope (m).
The slope of the line of best fit seems to be closest to 3.25, meaning it goes up about that much for every one unit it goes to the right.
The second choice is correct.
all you have to do is divide the biggest number by the smaller number
Answer:
The first one
Step-by-step explanation:
The required equation of the parabola is (y-5)² = 20(x+2)
<h3>Equation of a parabola</h3>
The standard equation of a parabola is expressed as;
(y-k)² = 4p(x-h)
where;
vertex = (h, k)
focus = (p+k, k)
directrix x = -p + h
Note that the directrix given will determine the type of the equation of a parabola
Given the following parameters
focus = (-2, 5) = (h, k)
x = -p + h
3 = p -2
p = 5
Substitute
(y-k)² = 4p(x-h)
(y-5)² = 4(5)(x-(-2))
(y-5)² = 20(x+2)
Hence the required equation of the parabola is (y-5)² = 20(x+2)
