Write an equation in slope-intercept form for the line with slope -7 and y-intercept 8 . Then graph the line.
The equation in slope-intercept form for the line with slope -7 and y-intercept 8 is y = -7x + 8. To graph the line, plot the y-intercept and use the slope to find other points on the line, connecting them to create the line.
Explanation:To write an equation in slope-intercept form, we use the formula y = mx + b, where m is the slope and b is the y-intercept. In this case, the slope is -7 and the y-intercept is 8, so the equation is y = -7x + 8.
To graph the line, first plot the y-intercept, which is the point (0,8). Then, use the slope to find other points on the line. Since the slope is -7, for every increase of 1 on the horizontal axis, the line decreases by 7 on the vertical axis. So, for example, if we move 1 unit to the right from the y-intercept, we go down 7 units. Plot these additional points and connect them to create the line.

The effect that multiplying the radius by 6 would have on the volume of the cylinder is the volume would increase by a factor of 36
Calculating the volume of a cylinderFrom the question, we are to determine what effect multiplying radius by 6 would have on the cylinder
Using the formula for calculating the volume of a cylinder
V = πr²h
Where V is the volume of the cylinder
r is the radius
and h is the height
If the r is the radius and h is the height of the first cylinder,
Then, volume of the first cylinder will be
V = πr²h
For the new cylinder
radius = 6r
and h = h
Then, volume of the new cylinder will be
V₂ = π × (6r)² × h
V₂ = π × 36r² × h
V₂ = 36πr²h
The new volume is multiplied by a factor of 36
Hence, the effect that multiplying the radius by 6 would have on the volume of the cylinder is the volume would increase by a factor of 36.

find the mean,median,and mode for the data.
114;120;115;114;118;117;114
pleassssseeee
thanks
:)
Answer:
Mean: 116
Median: 115
Mode: 115
Step-by-step explanation:
Mean is the average of the data set; it’s found by adding up all the numbers and dividing that sum by the number of numbers there are
(114 + 120 + 115 + 114 + 118 + 117 + 114)/7 = 812/7 = 116
Median is found out by ordering the given numbers from largest to smallest and finding the middle number; if there are an even number of given numbers, you add them up and divide by two.
In this case, you are lucky enough to be given an odd numbers of given numbers
Ordering (smallest to largest):
114, 114, 114, 115, 117, 118, 120
Median is 115
(this is the number in the middle of the data set)
Mode is the most frequently occurring number in the data set
In this case, the
Mode is 114
The mean of the data is 116, the median is 115, and the mode is 114. All three measures offer insights into the dataset's central tendencies.
To find the mean, median, and mode of the given data: 114, 120, 115, 114, 118, 117, 114, let's follow these steps:
Mean: Add all the numbers together and divide by the number of data points.
Sum: 114 + 120 + 115 + 114 + 118 + 117 + 114 = 812Number of data points: 7Mean: 812 / 7 = 116Median: Arrange the numbers in ascending order and find the middle value. If there is an even number of observations, calculate the average of the two middle values.
Ordered data: 114, 114, 114, 115, 117, 118, 120Since n = 7 (an odd number), the median is the 4th value which is 115Mode: The most frequently occurring value in the dataset.
Mode: 114 (appears 3 times)Thus, the mean is 116, the median is 115, and the mode is 114.
On a coordinate plane, the endpoints of line segment JK are J (-10, 12) K (8, -12). Point L lies on segment JK and divides it into two segments such that to LK is 5: 1. What are the coordinates of point L?
Answer:
(-7,8)
Step-by-step explanation:
The coordinates of the points dividing the line segment in ratio m:n can be calculated as:
[tex](\frac{mx_{1}+nx_{2}}{m+n} ,\frac{my_{1}+ny_{2}}{m+n} )[/tex]
Here x1, y1 are the coordinates of first point J (-10, 12) and x2, y2 are the coordinates of second point K(8, -12).
In this case m will be 5 and n will be 1 as the ratio is 5:1
Using all these values we can find the coordinates of point L
[tex]( \frac{5(-10)+1(8)}{5+1},\frac{5(12)+1(-12)}{5+1} )\\\\ = (\frac{-42}{6} ,\frac{48}{6} )\\\\ =(-7,8)[/tex]
Thus, the coordinates of point L which divides the line segment JK in 5:1 are (-7,8)
The coordinates of point L, which divides the line segment JK in the ratio 5:1, are (5,-8).
Explanation:To find the coordinates of point L that divides the line segment JK in the ratio 5:1, we use the formula for section formula in coordinate geometry. This formula provides the coordinates of a point that divides a line segment into a specific ratio. The formula is X = (m1*x2 + m2*x1) / (m1+m2), Y = (m1*y2 + m2*y1) / (m1+m2), where m1 and m2 are the ratios.
Here, J(-10,12) is x1,y1 and K(8,-12) is x2,y2. The point L is dividing JK in the ratio 5:1, so m1=5 and m2=1. Substituting these values:
X = (5*8 + 1*-10) / (5 + 1) = 30 / 6 = 5, Y = (5*-12 + 1*12) / (5 + 1) = -48 / 6 = -8.
Therefore, the coordinates of point L are (5,-8).

What’s the right triangle definition of tan theta
Final answer:
In mathematics, the right triangle definition of tan theta is the ratio of the length of the side opposite to theta (y) to the length of the side adjacent to theta (x).
Explanation:
The right triangle definition of tan theta (tan θ) involves the ratio of the lengths of two specific sides of the triangle. According to SOHCAHTOA, a mnemonic used to remember the definitions of the sine, cosine, and tangent functions, tan theta is the ratio of the opposite side (y) to the adjacent side (x) of the right triangle, where theta (θ) is one of the non-right angles. This can be written as tan(θ) = y/x.
In other words, the tangent of an angle θ in a right triangle is defined as the ratio of the length of the side opposite the angle to the length of the side adjacent to the angle.
This can be represented as:
tan(θ) = Opposite side / Adjacent side = y / x
For example, if the opposite side y is 5 units and the adjacent side x is 3 units, then tan(θ) = 5 / 3
The Pythagorean Theorem may be applied in conjunction with the definitions of trigonometric functions to solve various problems involving right triangles, but it specifically relates to the relationship between the sides of a right triangle: a² + b² = c², where 'a' and 'b' are the lengths of the legs, and 'c' is the length of the hypotenuse.
When solving problems related to right triangles, it is beneficial to remember that the sum of the angles of a triangle is always equal to two right angles (or 180 degrees).

Which of the following descriptions matches the sequence of events shown
in the tree diagram below?
The answer would be d- tossing s coin, tossing a second coin, and tossing a third coin
Option: D is the correct answer
D. Tossing a coin, tossing a second coin and tossing a third coin.
Step-by-step explanation:We know that when a coin is tossed then there are only two possible outcomes i.e. either a head or a tail.
Now, when a second coin is tossed then again we have two possible outcomes i.e. head and a tail.
and the total sample space of the two events is given by:
HH HT TT TH
Now, when a coin is tossed third time then in than two outcomes are possible on the coin i.e. a head and a tail.
Hence, the total number of outcomes are:
HHH HTH TTH THH
HHT HTT TTT THT
i.e. when a coin is tossed n times that the total possible outcomes are:
[tex]2^n[/tex]
Here the coin is tossed three times.
Hence, the total possible outcomes are: [tex]2^3=8[/tex]

Step-by-step explanation:
if we mention x =0 then y=-12 and we do the same with y if we mention y=0 then x=6 and x=-2 and we will find thes cases only in graph B
The solution is Option B.
The graph of the equation of line y = x² - 4x - 12 is given below , where the values of y = 0 at x = -2 and x = 6
What is an Equation of a line?
The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation of line be A
Now , the value of A is given as
y = x² - 4x - 12 be equation (1)
On factorizing the equation (1) , we get
y = x² + 2x - 6x - 12
So , on grouping the common terms , we get
y = x ( x + 2 ) - 6 ( x + 2 )
y = ( x + 2 ) ( x - 6 )
when y = 0
x + 2 = 0
On subtracting 2 on both sides , we get
x = -2
when y = 0
x - 6 = 0
On adding 6 on both sides , we get
x = 6
So , the value of y = 0 , when x = -2 and when x = 6
Substituting the values in the equation,we get the following graph
Therefore , the equation of line is y = ( x + 2 ) ( x - 6 )
Hence , The graph of the equation of line y = x² - 4x - 12 is given below , where the values of y = 0 at x = -2 and x = 6

A triangle is a three-edged polygon with three vertices. The measurement of the largest angle of the triangle is 93°.
What is a triangle?A triangle is a three-edged polygon with three vertices. It is a fundamental form in geometry. The sum of all the angles of a triangle is always equal to 180°.
Let the measure of the smallest angle be x. And as it is given that the measure of the second angle is 3 times the smallest, while the measure of the third angle is 25 more than the smallest angle. Therefore, the measure of the angles can be written as,
∠1 = x
∠2 = 3x
∠3 = x + 25
Since the sum of all the angles of a triangle is 180°, therefore, the sum can be written as,
∠1 + ∠2 + ∠3 = 180°
x + 3x + (x+25) = 180°
x + 3x + x + 25 = 180°
5x + 25 = 180°
5x = 180° - 25°
5x = 155°
x = 31°
Now, the measurement of all the angles is,
∠1 = x = 31°
∠2 = 3x = 3(31°) = 93°
∠3 = x + 25 = (31+25)° = 56°
Hence, the measurement of the largest angle of the triangle is 93°.

The population of a town is 13,000. It decreases at a rate of 5% per year. In about how many years will the population be less than 12,000?
This is an exponential decay problem.
Using the equation Y = a *(1-rate)^time
where Y is the future value given as 12,000 and a is the starting value given as 13,000.
The rate is also given as 5%.
The equation becomes:
12,000 = 13,000(1-0.05)^x
12,000 = 13,000(0.95)^x
Divide each side by 13000:
12000/13000 = 0.95^x/13000
12/13 = 0.95^x
Use the natural log function:
x = ln(12/13) / ln(0.95)
x = 1.56 years. ( this will equal 12,000
Round to 2 years it will be less than 12000.
