A parabola has focus (5,1) and directrix y=-3.
Where is the parabola’s vertex?
Answer:
vertex = (5, - 1 )
Step-by-step explanation:
The focus and directrix are equidistant from the vertex
Since the equation of directrix is y = - 3 then the parabola is vertical,
The distance between the focus and directrix is
| 1 - (- 3) | = | 4 | = 2
Thus the vertex is 2 units below the focus
vertex = (5, 1 - 2 ) = (5, - 1 )
A parabola has focus (5, 1) then the vertex of the parabola will be (5, -1).
What is a Parabola?A location on the curve that is equally spaced from both a fixed location and a fixed line is referred to as a parabola. The parabola's focus requires and fixed line are referred to as its foci and directrix, respectively.
As per the given information in the question,
The focus and directrix are equidistant from the vertex then,
The parabola is vertical because the directrix's equation is y = - 3; hence, the focus and directrix are separated by:
|1 - (-3)| = |4| = 2
The vertex is therefore 2 units below the focus.
vertex = (5, 1 - 2) = (5, -1)

can someone please help me is the answer-8
Answer:
h(-8)=-8
Step-by-step explanation:
Since we are finding h(-8), we plug -8 into the equation:
h(-8)=((-8)²+3(-8))/(4(-8)+27)
h(-8)=(64-24)/(-32+27)
h(-8)=40/-5
h(-8)=-8
Therefore, h(-8)=-8, which means your answer is correct!
A triangle prism has a volume of 240m3.The area of the base is 16m2 what's is the height of the triangle prism
Answer:
The height is 45 m
Step-by-step explanation:
The volume of a triangular prism is V = (1/3)(area of base)(height)
If the voume is 240 m^3 and the area of the base 16 m^2, then the height of the prism is determined as follows:
3V = (area of base)(height)
Dividing both sides by (area of the base), we get:
3(240m^3)
height = ------------------------- = 45 m
16 m^2

Step-by-step explanation:
To complete the square, add the square of half of the x-term coefficient.
Then use the factoring of a perfect square trinomial.
a^2 + 2ab + b^2 = (a + b)^2
a^2 - 2ab + b^2 = (a - b)^2

Answer:
A. When the team scored 52 points, the median number decreased.
Step-by-step explanation:
The median now is 88. Without the 52, (using the median formula,) it would become 88.5. Since 88.5 is larger than 88, it means the median decreased after 52 was added. There was no change when 91 was added.

Felix puts 6000 into saving bonds that pay a simple interest rate of 4.4 how much money will the bonds be worth at the end of 6 years
Answer:
$7,584
Step-by-step explanation:
The computation of the amount worth at the end of 6 years is shown below:
As we know that
SImple interest = Principal amount × rate of interest × time period
= $6,000 × 4.4% × 6
= $1,584
Now the amount at the end of 6 years is
= Principal amount + simple interest
= $6,000 + $1,584
= $7,584
Hence, the amount would be $7,584

Can u find the value of the x.
Answer:x=8
Step-by-step explanation:
x²-3x=-3x+64
- Add 3x to both sides
x²-3x+3x=-3x+3x+64
= x²=64
- Square both sides
√x²=√64
x=±8
- Since the question is asking for the positive value of x, the answer is 8.

Theo has x beach toys. He shares them with 6 other friends. Each of them got 4 beach toys. Find x. Show all work
Answer:
24 beach toys
Step-by-step explanation:
We don't know how many beach toys Theo has, but we know that 6 of his friends each got 4 toys. The equation could be set up as x/6 = y, where x is equal to the total amount of toys Theo had, and y is equal to the amount of toys each friend received. We know that y = 4, so now you could say x/6 = 4, and now using opposite operations, 6 × 4 = 24, hence Theo had 24 toys.
Hope this helps!!
