The focus of the parabola is at the point (0, 2).
What is the focus of the parabola?A parabola's focus can be found on the side of the concavity, at the same distance from the vertex as from the directrix, and at the same distance from the vertex to the parabola's centre of gravity.
This is actually a great geometrical characteristic of the parabola and the way it may be built using its definition. all those lane sites whose distance from the directrix to the focus is equal.
Then, the focus must be at a distance of two units from the vertex, (0,0), in line with the parabola's axis of symmetry (x=0), and on the positive side of the y-axis (notice the directrix is on the negative side of the y-axis.
So, the focus of this parabola at the point (0, 2).

=110
Answer:
No solution (C)
Step-by-step explanation:
System of Linear Equations given :
[1] 7x + 4y = 16
[2] 42x + 24y = 110
Solve by Substitution :'
// Solve equation [2] for the variable y
[2] 24y = -42x + 110
[2] y = -7x/4 + 55/12
// Plug this in for variable y in equation [1]
[1] 7x + 4•(-7x/4+55/12) = 16
[1] 0 = -7/3 => NO solution

Step-by-step explanation:
To solve this problem, we first do two thirds of 180, and then we do one fifth of the solution you got for "two thirds of 180"
[tex]\mathrm{Two\:thirds\:of\:180 = (\frac{2}{3}) 180\:\:or\:\:\frac{2}{3}\times180}[/tex]
[tex]\mathrm{Turn\:\frac{2}{3}\:into\:a\:decimal,\:by\:dividing\:2\:by\:3}[/tex]
[tex]\mathrm{0.6666666666666667\times180}[/tex]
[tex]\mathrm{Multiply\:0.6666666666666667\:and\:180}[/tex]
[tex]\mathrm{120}[/tex]
Now we do one fifth of 120
[tex]\mathrm{One\:fifth\:of\:120 = (\frac{1}{5})120\:or\:\frac{1}{5}\times120}[/tex]
[tex]\mathrm{Turn\:\frac{1}{5}\:into\:a\:decimal,\:by\:dividing\:1\:by\:5}[/tex]
[tex]\mathrm{0.2\times120}[/tex]
[tex]\mathrm{Multiply\:0.2\:and\:120}[/tex]
[tex]24[/tex]
So the answer to "What is one fifth of two thirds of 180", would be 24
By multiplying the number by the corresponding fractions, we can see that the fifth part of two-thirds of 180 is 24.
How to get the fifth part of two thirds of 180?The fifth part of two-thirds of 180 is 24.
To calculate it:
Step 1: Find two-thirds of 180, Just multiply the fraction 2/3 by the number
(2/3) * 180 = 2 * 180 / 3 = 360 / 3 = 120
Step 2: Find the fifth part of the result from Step 1, similar like we did above, multiply the number by the fraction 1/5.
(1/5) * 120 = 120 / 5 = 24
So, the fifth part of two-thirds of 180 is 24.

How much water can the swimming pool hold?
Answer:
The pool can hold 3,136 cubic feet of water
Step-by-step explanation:
To know how much water the pool can hold, we need to find the volume of this swimming pool, because the volume is how much a container can hold.
The formula for volume is L*W*H (length times width times height)

please PLEASE help me!!! Write an expression that can be used to produce vector r from vectors p and q. Explain how you determined that expression
Answer:
r = p - q
Step-by-step explanation:
Write the two given vectors using i and j components.
i = unit vector in x direction
j = unit vector in y direction
p = -i - 3j
q = 3i - 4j
Now how can you combine these two vectors and get r when
r = -4i + j?
Adding p and q gives this:
p + q = -i - 3j + 3i - 4j = 2i - 7j
That is not r, so the addition of the vectors p and q does not work.
How about subtraction?
Start with -i from p and subtract 3i from q. You do get -4i which is the x-component of r.
Then start with -3j from p and subtract -4j from q. You get -3j - (-4j) = -3j + 4j = j which is the y-component of r.
That subtraction works.
p - q = -i - 3j - (3i - 4j) = -i - 3j - 3i + 4j = -4i + j which is exactly what r is.
Answer: r = p - q

The equation having a sum that is a whole number is 0/5 + 1/5 + 2/5 + .... + 5/5
What is an whole number?A whole number means a number that does not include any fractions, negative numbers or decimals.
Given that, number sentences show a pattern in the sum of the fractions from 0 to 1 for different denominators,
1) 0/5 + 1/5 + 2/5 + .... + 5/5 =
1/5(0 + 1 + 2 + 3 + 4 + 5) = 1/5(15) = 3 [whole number]
2) 0/6 + 1/6 + 2/6 + .... + 6/6 =
1/6(0 + 1 + 2 + 3 + 4 + 5 + 6) = 21/6 = 7/2 [fraction]
3) 0/8 + 1/8 + 2/8 + .... + 8/8 =

show all of your work.
Answer:
A. f(0) = 4
B. f(6) = 8
Step-by-step explanation:
When evaluating a piecewise function, the fist step is to determine the applicable domain. Then the function defined for that domain is the one that is used for the evaluation.
A.x = 0 is in the domain x < 5, so the applicable function is f(x) = x+4.
f(0) = 0 +4 = 4

B.x = 6 is in the domain 5 ≤ x < 7, so the applicable function is f(x) = 8.
