The slope of the line is indefinite (∞). Also, the line will be parallel to the x-axis.
It is given in the question that a line passes through the points (7, 10) and (7, 20).
We have to find the slope of the line.
We know that,
Slope of a line with coordinates (a,b) and (c,d) is given by:-
(d - b)/( c - a)
Here,
a = 7,
b = 10,
c = 7 and,
d = 20
Hence, we can write,
Slope of the line = (20 - 10)/( 7 - 7) = 10/0 = ∞.
Hence, the slope of the line is indefinite.
Here, as the x -coordinate of both the points are same, this line will be parallel to the x - axis.

What is a function?A function is a relation in which each element of the domain is associated with exactly one element of the codomain.
A relation can be tagged a function if it describes that there should be only one output (y - value) for each input ( x - value). Put simply, a function is a kind of relation (defined by a set of ordered pairs) in which case, it ensures that every x-value is associated with only one y-value.
On this note, since the relation described in the first answer choice is such that every x-value is associated with only one y-value as it is a parabola (quadratic function), it is termed a function.

Consider the incomplete paragraph proof.
Given: P is a point on the perpendicular bisector, l, of MN.
Prove: PM = PN
Line l is a perpendicular bisector of line segment M N. It intersects line segment M N at point Q. Line l also contains point P.
Because of the unique line postulate, we can draw unique line segment PM. Using the definition of reflection, PM can be reflected over line l. By the definition of reflection, point P is the image of itself and point N is the image of ________. Because reflections preserve length, PM = PN.
Given that P is a point on the perpendicular bisector, l, of MN, we have proved that PM = PN because By the definition of reflection, point P is the image of itself and point N is the image of N.
How to Interpret the Perpendicular Bisector?We are given :
P is a point on the perpendicular bisector, l, of MN.
Now, we want to prove that PM = PN
A Reflection is a transformation in which the figure is the mirror image of the other. Every point is a mirror reflection of itself .
By the definition of reflection, we can deduce that point P is the image of itself , and point N is the image of M .
The line l acts as a Line of symmetry or axis of reflection.
Now, in transformations, we know that reflections preserve length and as a result, PM = PN.

intercept form.
Answer:
y = 1/3 x + 3
Step-by-step explanation:
1) when finding a perpendicular line, you take the slope and use the reciprocal (you flip it) and change the sign (from negative to positive or positive to negative)
-3 ---> 1/3
2) plug in the slope into a new equation
y=1/3 x + b
3) plug in the points
3= 1/3 (0) + b
b=3
4) rewrite the equation

f (x)=
Lowest degree polynomial with f(0) = 960 with zeros of -4 (multiplicity 3), 3(multiplicity 1). The polynomial is f(x)=-5(x+4)³(x-3).
Given that,
Lowest degree polynomial with f(0) = 960 with zeros of -4 (multiplicity 3), 3(multiplicity 1)
We have to find the polynomial of f(x) which satisfy the conditions.
Here,
We have the zeros of the polynomial are -4 (multiplicity 3), 3(multiplicity 1)
Which we can write as -4,-4,-4,3 are the zeros.
Then we can write the polynomial as
f(x)=ω(x+4)³(x-3)
We have to first find the value of ω.
So,
We have f(0)=960
ω(0+4)³(0-3)=960
ω(4)³(-3)=960
64ω(-3)=960
-192ω=960
ω=960/-192
ω=-5

Which linear function has the same slope as the one that is represented by the table?
y = -1/5x +1/2 linear function has the same slope .
What is slope ?A line's steepness and direction are measured by the line's slope. Without actually using a compass, determining the slope of lines in a coordinate plane can assist in forecasting whether the lines are parallel, perpendicular, or none at all. Any two different points on a line can be used to calculate the slope of any line. The ratio of "vertical change" to "horizontal change" between two different locations on a line is calculated using the slope of a line formula. We shall comprehend the slope-finding method and its applications in this essay.
First solve for the slope
m =[tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]
m=[tex]\frac{0-\frac{3}{5} }{\frac{1}{2} -\frac{1}{5} }[/tex]
m = [tex]\frac{-1}{5}[/tex]

Answer:
P(A|B) = 1/2
Step-by-step explanation:
Sample space for B = {10, 20, 30, 40, 50, 60, 70, 80}
where B is even
Total number of elements in sample space = 8
P(A|B) = Probability of a number being 40 or less from the sample space of 8
Sample space for A|B = {10, 20, 30, 40}
So out of a possible 8 elements in the sample space for B only 4 elements can be chosen for the sample space of A
So P(A|B) = 4/8 = 1/2

From the figure, we can see that the corresponding vertical lines of either triangle are parallel (but not equal)
This means that, the triangles are similar triangles
This is so because the other two sides of the smaller triangle lie completely on the bigger triangle
As a general rule, the corresponding sides of similar triangles are in proportions
So, we can say that the corresponding side lengths of the triangles are similar

An equation of the line in point-slope form is y = 6x + 50.
Define point slope form.y = y₁ = m(x -x₁) is the equation of a straight line, where m is the slope and (x₁, y₁) are the coordinates at a given point on the line (see slope-intercept form). When you know the slope and another point on the line, the point-slope form of a linear equation is most helpful for locating a point on a line. When two other points are known, it can also be used to locate a point on a line.
Given,
y₂ = 200
y₁ = 230
x₂ = 30
x₁ = 25
Slope = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

What is defined as the exponential population growth?In exponential growth, the per capita (per person) growth rate of a population remains constant regardless of population size, causing the population to grow faster and faster as it grows larger.The logistic growth rate of a population decreases as population size approaches a maximum imposition by limited resources available in the environment, recognised as the carrying capacity (K).The base growth rate = 4.3%.
The current carrying capacity = 62 million.
The actual fractional growth for the given values are-
growth rate = r * (1 - population/carrying capacity)
a) population = 10 million,

suppose you are35 years old and would like to retire at age65 . Furthermore, you would like to have a retirement fund from which you can draw an income of $150000 per yearforever! How much would you need to deposit each month to do this? Assume a constant APR of8 % and that the compounding and payment periods are the same.
Answer:
$1258.09
Step-by-step explanation:
You want the monthly annuity payment that will let you withdraw $150,000 per year forever from an account earning 8% after 30 years.
Account balanceIn order to withdraw an amount "forever," the withdrawal amount must be equal to the interest earned by the account.
I = Prt
150,000 = P(0.08)(1)
P = 150,000/0.08 = 1,875,000
Annuity paymentThe value of an ordinary annuity is given by the formula ...
A = P(12/r)((1 +r/12)^(12t) -1) . . . . . where P is the monthly payment, and r is the annual interest rate earned over a period of t years.
Using the values we know, we can find P:
1875000 = P(12/0.08)((1 +0.08/12)^(12·30) -1) = 1490.359449P
P ≈ 1258.09
