Step-by-step explanation:
The standard form of a parabola is
If we know the y intercept is (0, 400), that means that when x = 0, y = 400. That allows us to begin by finding c:
and c = 400.
Now to find a and b. Using the fact that the vertex is (1, 405), we know that h is 1 and k is 405. If
and h = 1, then
and
2a = -b so
b = -2a. Save that for a minute or two.
If
and k = 405, then
and
and
405 = 400 - 4a and
5 = -4a so
We will use that a value now to find the value of b. If b = -2a, then
and
Writing our parabolic equation now:
Finding the x-intercepts is just another way of saying "factor this quadratic" so we will begin that by setting the quadratic equal to 0:
and who hates all those fractions more than I do? Probably nobody, so we are going to get rid of them by multiplying everything by 4 to get
Assuming you can throw that into the quadratic formula to solve for the 2 values of x where y = 0, you'll find that the x-intercepts are
x = -16.91647287 and 18.91647287

Answer:
11 + m > -23
Step-by-step explanation:
Given simplification:
3√7 + 7√63 + (√7/7)
= 3√7 + 7√(9*7) + (√7/7)
= 3√7 + 7*3√7 + (√7/7)
= 3√7 + 21√7 + (√7/7)
= (3+21)√7 + (√7/7)
= 24√7 + (√7/√7)
= (7*24√7 + √7)/7
= (168√7 + √7)/7
= (169√7)/7
