Answers
Answer:
circle
Step-by-step explanation:
lol where teh f parabola come from
if it's perpendicular it makes a 90 degree angle to the central axis
that would make it a circle...
parabolas r when the plane forms the same angle w the central axis as the generator..............................
A conic section which is formed by a plane intersecting a double-napped cone that is perpendicular to the central axis is a: A. circle.
What is a circle?A circle can be defined as a closed, two-dimensional curved geometric shape with no edges or corners. Also, it refers to the set of all points in a plane that are located at a fixed distance (radius) from a fixed point (central axis).
In Geometry, a circle is a conic section which is formed by a plane intersecting a double-napped cone that is perpendicular to the central axis because it forms an angle of 90° with the central axis.

Judge the following reasoning as true or false.
You are working for a tech company. You came up with an algorithm that performs a needed operation on n inputs in order of n operations. Someone else in the company simultaneously came up with an algorithm that performs the same task in order of log(n) operations. Then it follows necessarily that your algorithm will require more operations to perform this task and is therefore inferior and should not be used.

What is the equation, in slope-intercept form, of the line that passes through (0, 6) and has a slope of 4 (5 points)
Answers
Answer: y=4x+6
Step-by-step explanation: you replace the variables in the equation with the variables in the point given to find b.
Answer:
[tex]y = 4x+6[/tex]
Step-by-step explanation:
Equation of a line
The equation of a line can be written in the form:
[tex]y = mx+b[/tex]
Where m is the slope of the line and b is the y-intercept. We are given the value of m=4, thus the equation becomes:
[tex]y = 4x+b[/tex]
To find the value of b, we use the point (0,6):
[tex]6=4*0+b[/tex]
Solving:
[tex]b=6[/tex]
Thus, the equation in slope-intercept form of the required line is
[tex]\boxed{y = 4x+6}[/tex]

Jade and Jackson are considering a $210,000 mortgage for 30 years at 5.7%. With this information, their monthly payment would be $1218.84.
If they make only the minimum payment each month, what is the total payback of this loan?
How much of this total payback is interest?
Answers
Answer:
Jade and Jackson
The total payback of this loan = $438,782.72
The interest of this total payback is $228,782.72
Step-by-step explanation:
a) Data and Calculations:
Mortgage = $210,000
Interest rate of mortgage = 5.7%
Monthly payment = $1,218.84
Using an online calculator for Mortgage Payoff, the Original Payoff Schedule is:
Monthly Pay = $1,218.84
Total Payments = $438,782.72
Total Interest = $228,782.72
Answer:
Step-by-step explanation:
1218.84⋅12⋅30=$438,782.40
The total interest paid is the total payback less the amount borrowed.
$438,782.40−$210,000=$228,782.40

How do you do this question?
Answers
For A to B, or segment AB, we have the points (1,1) and (4,3). (x1, y1) = (1,1) and (x2, y2) = (4,3);
x = 1 + t(4 - 1)
y = 1 + t(3 - 1)
A to B => (x = 1 + 3t, y = 1 + 2t)
We can apply a similar process for BC and AC. For BC we have (x1, y1) = (4,3) and (x2,y2) = (1,7);
x = 4 + t(1 - 4)
y = 3 + t(7 - 3)
B to C => (x = 4 - 3t, y = 3 + 4t)
(x1, y1) = (1, 1) and (x2, y2) = (1, 7);
x = 1 + t(1 - 1)
y = 1 + t(7 - 1)
A to C => (x = 1, y = 1 + 6t)

Find the intercepts of the given line:
y=−6x+21
Answers
Answer:
x-intercept = 3.5y-intercept = 21Step-by-step explanation:
x-intercept is for y = 0
y-intercept is for x = 0
Substitute
For y = 0
-6x + 21 = 0 |subtract 21 from both sides
-6x = -21 |divdie both sides by (-6)
x = -21/(-6)
x = 21/6
x = 3.5
For x = 0
y = -6(0) + 21
y = 0 + 21
y = 21
So (0,21) is the starting point and if you rise -6 and run 1 you get (15,1) and you keep doing that until u get a line
