Answer with explanation:
A parabola is the locus of all the points such that distance from a fixed point called focus to distance from a fixed line is always constant equal to 1.
Let locus of all the point be (p,q).
[tex]\rightarrow \sqrt{(p-4)^2+(q-0)^2}=p+4\\\\ \rightarrow \text{Squaring both sides}\\\\\rightarrow p^2+16-8 p+q^2=p^2+8 p+16\\\\\rightarrow q^2=8 p+8 p\\\\\rightarrow q^2=16 p\\\\\rightarrow y^2=16 x[/tex]

In general, reducing the interest rate (i) of a credit card but keeping the present value (PV) and number of periods (n) the same will __________. a. decrease the monthly payment (P) needed to pay off the debt b. increase the monthly payment (P) needed to pay off the debt c. eliminate the monthly payment (P) needed to pay off the debt d. have no effect on the monthly payment (P) needed to pay off the debt
Answers
Monthly payments would increase if the interest rate increases. Monthly payments cannot be eliminated.
A) decrease the monthly payment (P) needed to pay off the debt.
Explanation:
When calculating the monthly payment, the interest rate affects the amount you pay.
The higher the interest rate is, the more you must pay monthly in order to pay the debt off within the same number of time periods.
However, if you lower the interest rate, the reverse will be true; you will need to pay less money each month in order to pay off the debt within the same amount of time.

A number has the digits 9 and 7. To the nearest 10, the number rounds to 100. what is the number?
Answers
Answer:
97
Step-by-step explanation:
The digits formed by 9 and 7 (without repetition) are 79 and 97. In rounding off a number to the nearest tens, the number in the unit position is considered.
If that number is less than 5, it is changed to 0. However, where the number is above 5, 1 is added to the number in the tens place with the number in the unit place changed to 0.
Going by the above explanation, 79 rounds off to 80 while 97 rounds off to 100.

Which point is on the line that passes through (0,6) and is parallel to the given line
Answers
Anyways, take the slope of the given line. Since I don’t know what it is, let’s say it’s one.
Create an equation for the new line. Y=1x+b
We know that the line must go through (0,6). Plug in that. 6=0+b
B=6
Now plug b in to get your equation. y=x+6
This will change based on what your slope is
Points depends on the value of slope for the parallel line y = m₁ x + 6.
What are parallel lines?
" Parallel lines defined as two different lines lie in the same plane and never intersect with each other in that plane. Distance between parallel lines remain constant."
According to the question,
Let y = m₁ x + d be the given line.
Slope of parallel lines are equal and line passes through (0, 6)
Therefore,
6 = m₁ (0) + d
⇒ 6 = d
Required line parallel to the given line is
y = m₁ x + 6
Hence, points depends on the value of slope for the parallel line
y = m₁ x + 6.

What is right rectangular prism?
A right rectangular prism is a three dimensional object with six faces, twelve edges, and eight vertices.
Formula for the volume of right rectangular prism:volume of right rectangular prism = length × width × height
According to the given question we have,
length of the prism = 45cm
width of the prism = 12cm
height of the prism = 10cm
Therefore,
The volume of the right rectangular prism = length × width × height

The volume of a cylinder is given by the formula mc021-1.jpg, where r is the radius of the cylinder and h is the height. Which expression represents the volume of this cylinder? r=x-3 h=2x+7
Answers
r= x-3, while h =2x+7
Thus; volume = π(x-3)²(2x+7)
=π(x²-6x+9)(2x+7)
=π( 2x³-12x²+18x +7x²-42x+63
= π(2x³-5x²+24x+63) cubic units
It can be express as follows: v = π(2x³- 5x²- 24x + 63) cubic unit
The volume of a cylinder is given as follows
volume = πr²h
where
h = height
r = base radius
Therefore,
r = x - 3
h = 2x + 7
Therefore,
The volume can be express as follows
v = π × (x-3)² × (2x + 7)
v = π × x² - 6x + 9 ×(2x + 7)
v = π × 2x³- 12x² + 18x + 7x² - 42x + 63
v = π × 2x³- 5x²- 24x + 63
v = π(2x³- 5x²- 24x + 63) cubic unit

Answers
Answer:
∵ MON ≅ RTS
∴ The answer is C. RTS.
Step-by-step explanation:
When two triangles are congruent, they will have congruent pairs of vertices. Each vertex in one triangle will have a partner in the other triangle.
Congruent vertex pairsIf we look at ΔMON, we can see it is almost like a right triangle, with:
'M' as the almost-right angle;'O' at the end of the long side, and;'N' at the end of the short side.In the next triangle, each letter has to be in the same order as the congruent vertex in ΔMON.
This triangle is ΔRTS, with:
'R' as the almost-right angle;'T' at the end of the long side, and;'S' at the end of the short side.Thus, the pairs of congruent angles are:
M ≅ RO ≅ TN ≅ SWhen we write the statement of congruence, we order the letters by their congruent pair.

You work as a coordinator for data entry projects. On one project, the status report shows that 15% of the work was completed in 6 days. If the work progresses at the same rate, how many more days will be required to complete the remainder of the project?
Answers
Answer: They need 34 more days to complete the remainder of the project.
Step-by-step explanation:
Since we have given that
Number of days the work was done = 6 days
Part of work is completed in these days = 15%
If the work is done at the same rate,
then the remaining part of work is done in how many days.
Remaining part of work is 100% - 15% = 85 %
So, it becomes,
[tex]\dfrac{6}{0.15}=\dfrac{x}{0.85}\\\\x=\dfrac{6\times 0.85}{0.15}=34\ days[/tex]
Hence, they need 34 more days to complete the remainder of the project.
