50 POINTS!! What is (-4, 3) (-3, -1) in point slope form?
Y=4x+16
Y-3=-4(x+4)
Explanation:
[tex]\bf point \ slope \ form: y-y_{1}=m\left(x-x_{1}\right)[/tex]
Find the slope: given points: (-4, 3), (-3, -1)
[tex]\sf slope: \dfrac{y_2 - y_1}{x_2- x_1} \ \ where \ (x_1 , \ y_1), ( x_2 , \ y_2) \ are \ points[/tex]
Insert values
[tex]\rightarrow \sf slope: \ \dfrac{-1-3}{-3-(-4)} =-4[/tex]
Equation in point slope form:
[tex]\sf\rightarrow y - 3 = -4(x - (-4))[/tex]
[tex]\sf\rightarrow y - 3 =-4(x + 4)[/tex]
Additional, in slope intercept form:
[tex]\sf\rightarrow y = mx + b \quad where \ 'm \ is \ slope' \ and \ 'b \ is \ y-intercept'[/tex]
[tex]\sf\rightarrow y = -4 x - 16 +3[/tex]
[tex]\sf\rightarrow y = -4x -13[/tex]
Michael Jordan scores the following points over 8 games: 24, 17, 28, 19, 23, 20, 13, 19. What is the mean (average) number of points she scored over those 8 games
Answer:
19
Step-by-step explanation:
Answer:
20.375
Step-by-step explanation:
To calculate the mean, in this situation, you first add up the game scores and divide it by the amount of games.
So, first we add 24+17+28+19+23+20+13+19 = 163
Because there are 8 games, we do 163 / 8 = 20.375
or 20.4 to 1dp

Charles would like to buy a new car that costs $32 000. The dealership offers to finance the car at 2.4%/a, it's best for Charles loans from the bank to buy car.
Which is the best way to buy a car?Generally, the equation for the monthly loan payment is mathematically given as
[tex]R=\frac{\frac{iP}{N}}{1-(\frac{1}{N})^{NY}}[/tex]
Therefore
[tex]R=\frac{\frac{0.024*32000}{12}}{1-(\frac{0.024}{12}+1)^{-12*5}}[/tex]
R=566.51
Hence the total payment is
T=R*N*Y
T=33990.34
By taking a loan of 29000, and applying the equation
T'=33155.77

Solve the proportion: 35=x20
Answer:
either x = 1.75 or x = 700 , question wasn't clear
Step-by-step explanation:
Because you put the x in front of 20 , you might be meaning x/20 (second answer listed)? Or, you put the variable on the wrong side of 20. (first answer listed)
If you meant to type 20x
35 = 20x

x = 1.75
(x = [tex]\frac{35}{20}[/tex])

Answer: medians in a triangle.
The intersection of the three altitudes is the orthocenter.The intersection of the three perpendicular bisectors is the circumcenter.The intersection of the three angle bisectors is the incenter.The intersection of the three medians is the centroid.2. Consider the following dot plot and answer the following questions : A. Find the measures of central tendency Construct the Box Plot
The measures of central tendency for this data set are as follows:
Mean = 3.55.Median = 3.5.Mode = 3.How to calculate measures of central tendency?In Mathematics, there are three (3) main measures of central tendency and these include the following:
MeanMedianModeFor the mean, we have:
Mathematically, the mean for this data set would be calculated by using this formula:
Mean = [F(x)]/n
For the total number of data, we have:
F(x) = 0 + 1 + 1 + 1 + 2 + 2 + 3 + 3 + 3 + 3 + 4 + 4 + 4 + 5 + 5 + 5 + 6 + 6 + 6 + 7
F(x) = 71
Substituting the parameters into the formula, we have:
Mean = [F(x)]/n
Mean = 71/20
Mean = 3.55.
For the median, we have:
First of all, we would order the data from lowest to highest and then determine the median as follows:
Data = {0, 1, 1, 1, 2, 2, 3, 3, 3,} 3, 4, {4, 4, 5, 5, 5, 6, 6, 6, 7}
Median = {3 + 4}/2
Median = 7/2
Median = 3.5.
How to calculate the mode?A mode refers to the most frequently occurring number in a data set. Thus, the mode for this data set is equal to 3.

What are Function?Function are mathematical statement which links an independent variable to dependent variable.
It always comes with a defined domain and range.
The equation mentioned is incorrect in the question w.r.t. to the solutions mentioned, The right equation is

This function can also be written as
[tex]\rm f(x) = \dfrac{3 x^2}{x^{2}-2^2}\\\\\rm f(x) = \dfrac{3 x^2}{(x+2)(x-2)}[/tex]
Vertical asymptotes are defined when the denominator of a rational function tends to zero.
To find the equation/s let the denominator equal zero.
Denominator tends to zero for x = -2 and x = +2
Horizontal Asymptote is when the function f(x) is tending to zero.
for x = +∞ and x = - ∞
Let the rational function [tex]f(x)= \dfrac{mx^a}{nx^b}[/tex] where and a and b are degree of numerator and denominator.
If a < b , then the y axis y = 0 is a horizontal asymptote.
If b = a then horizontal asymptote is the line y = p/q
Here the value is b = 2 and a = 2
Since b = a the horizontal asymptote is the line
y = m/n where m = 3 and n = 1
Therefore y = 3
So , vertical asymptotes x = - 2, 2
Horizontal asymptotes y = 3

You play a game that requires rolling a six-sided die and then randomly choosing a colored card from a deck containing 3 red cards, 6 blue cards, and 8 yellow cards. Find the probability that you will roll a 5 on the die and then choose a red card.
The probability of getting a red card and rolling a 5 is = 3/85
How to find the probability?First, we want to find the probability of rolling a 5.
There are 6 outcomes on the six-sided die, so the probability of getting a particular value is:
P = 1/5.
Then, the probability of randomly drawing a red card is given by the quotient between the number of red cards and the total number of cards:
P' = 3/(3 + 6 + 8) = 3/17
The joint probability is given by the product between the individual probabilities:
prob = P*P' = (1/5)*(3/17) = 3/85

A fighter tank targets an enemy helicopter flying at an altitude of 1250 ft. If the ground
distance between the tank & the helicopter is 875 ft, what angle of elevation must the
cannon be raised to in order to hit the target?
By using trigonometric relations, we will see that the angle of elevation must be 55°.
How to find the angle of elevation?
We can see this as a right triangle, where one cathetus measures 1250ft (altitude) and the other cathetus measures 875ft.
The angle of elevation is the angle such that the adjacent cathetus is the one measuring 875ft.
Then we can use the relation:
tan(a) = (opposite cathetus)/(adjacent cathetus)
tan(a) = 1250ft/875ft
To find the angle of elevation, we can use the inverse tangent function:
a = Atan(1250ft/875ft) = 55°
The angle of elevation must be 55 degrees.

The line passes through point (0,6) and has a slope of 7. The equation of the line is?
Answer:
y = 7x + 6
Step-by-step explanation:
The general equation for a line in slope-intercept form is:
y = mx + b
In this form, "m" is the slope and "b" is the y-intercept. Remember, the y-intercept is the y-value when x = 0. As such, the point (0,6) gives you the y-intercept.
You have been given the slope (7) and the y-intercept (6). Therefore, you can just substitute these values in for their variables to determine the equation of the line.
slope = m = 7
y-intercept = b = 6
y = mx + b
y = 7x + 6
