Answer:
wow good luck mines due in 5 mins and im stuck hahah
Step-by-step explanation:
The equation for
the standard form of parabola is given as:
y = A (x - h)^2 +
k
with (h, k) being
the (x, y) coordinates of the vertex
For the given
problem, we are given that (h, k) = (5, - 12).
We can then use point (0, 63) for x and y to solve for A
63 = A (0 - 5)^2 - 12
75 = A (25)
A = 75 / 25
A = 3
Equation of given
parabola:
y = 3 (x - 5)^2 - 12
We can now solve for the x –intercept:
Set y = 0, then solve for x
0 = 3 (x - 5)^2 -
12
3 (x - 5)^2 = 12
(x - 5)^2 = 4
Taking sqrt of
both sides
x - 5= ±2
x = -2 - 5 = -7
and x = 2 - 5 = - 3
x = -3, -7
Answer:
x-intercepts of given parabola: -3 and -7
(-3, 0) and (-7,
0)
<span> Of course you're looking for the ratio: (17+7i)/(3+2i). To get a clear number, you need to get a real number at the denominator -- and it so happens that the product of two complex conjugates is a real number. So, you multiply the denominator and the numerator by the conjugate of 3+2i. The denominator becomes 13 and the numerator becomes 51 + 7i. Hence, the multiplier is 51/13 + 7/13 i. </span>
<span>As a side note, while you probably knew how to factor a difference of squares, I just showed how to factor a sum of squares: a^2 + b^2 = (a + bi)(a - bi). That holds because i^2 = -1.
Hope this's useful/helpful !!!^_~!!!</span>

Answer:
2.25 miles of road they have to build this week
Step-by-step explanation:
Given:
Total distance of the road = 3 miles
Distance constructed on Tuesday = 1/4 mile of road.
To Find:
Miles of road still have to be built this week=?
Solution:
Let the Distance that have to be built be X
Then,
X= total distance of the Road – the distance built on Tuesday
X = 3 – 
X = 3 - 
X =
X= 
X= 2.25 miles
