Answer:
D
Step-by-step explanation:
From any point (x, y) on the parabola the focus and directrix are equidistant
Using the distance formula
= | y + 1 |
Squaring both sides
(x + 5)² + (y - 5)² = (y + 1)^2 , that is
(y + 1)² = (x + 5)² + (y - 5)² ← subtract (y - 5)² from both sides
(y + 1)² - (y - 5)² = (x + 5)² ← expand left side and simplify
y² + 2y + 1 - y² + 10y - 25 = (x + 5)²
12y - 24 = (x + 5)² ← factor left side
12(y - 2) = (x + 5)² ← divide both sides by 12
y - 2 = 
(x + 5)² ← add 2 to both sides
y = (x + 5)² + 2
or
f(x) = (x + 5)² + 2 → D
1,844,938
to round to nearest thousand
we see the hundredth digit
So the answer is 1,845,000
and to round to nearest 100,000
we see the ten thousandth digit
So the answer should be 1,800,000
Answer:
(a-b-c)(X^2-Y)
Step-by-step explanation:
DONE!!
We are given the function expressed as:
<span>h(t) = 300 – 16t
where h is the height of the ball in time t.
We calculate the height at time equal to 2.4 seconds as follows:
</span>h(t) = 300 – 16(2.4)
h(t) = 261.6 ft
Hope this answers the question. Have a nice day.
Answer:
(12,-8)
