Consider the scatter plot.
Scatter plot with line of best fit of y equals 0.75x plus five.
The line of best fit is y = 0.75x + 5.
Choose the best representation for the slope.
The slope of the line of best fit shows that each additional minute, the distance increases by 0.75 feet.
The slope of the line of best fit shows that each additional minute, the distance decreases by 5 feet.
The slope of the line of best fit shows that each additional minute, the distance decreases by 0.75 feet.
The slope of the line of best fit shows that each additional minute, the distance increases by 5 feet.
Answer:
The correct answer option is: The y-intercept of the line of best fit shows that when time started, the distance was 5 feet.
Step-by-step explanation:
We are given a scatter plot with a best fit line as shown on the given graph.
The equation of the best fit line is given by:
y = 0.75x + 5
So with the help of the equation and by looking at the given graph, we can conclude about the representation of the y intercept that the the y-intercept of the line of best fit shows that when time started, the distance was 5 feet.
Since the distance shown on the y axis is already 5 when the time started at 0 minutes.

Use the dot product to find |v| when v=(-8,2)
Answer:
2√17
Step-by-step explanation:
V = (-8, 2)
|v| = √((-8)^2 + 2^2)
= √(64 + 4)
= √68
= √4* √17
= 2√17
Answer:
= 2 sqrt(17)
Step-by-step explanation:
To find the magnitude of v using the dot product
|v| = sqrt(v1*v1 + v2*v2)
= sqrt( -8*-8 + 2*2)
= sqrt(64+ 4)
= sqrt(68)
= sqrt(4*17)
= sqrt(4) sqrt(17)

Solve 14.2 divided by 0.5 dhow your work and explain how you new where thr decamal point whas going to be
Final answer:
To solve the division problem 14.2 divided by 0.5, you can use the long division method. The quotient is 28.4.
Explanation:
To solve the division problem 14.2 divided by 0.5, we can perform the long division method. Here's the step-by-step process:
Place the dividend, 14.2, inside the division bar.Place the divisor, 0.5, outside the division bar.Divide the first digit of the dividend, which is 1, by the divisor. The result is 2.Write down the quotient, 2, above the division bar.Multiply the quotient, 2, by the divisor, 0.5, which gives you 1.Subtract the product, 1, from the first digit of the dividend, 1, which gives you a remainder of 0.Bring down the next digit, which is 4, from the dividend.Divide the new dividend, 4, by the divisor, 0.5. The result is 8.Write down the new quotient, 8, next to the previous quotient.Multiply the new quotient, 8, by the divisor, 0.5, which gives you 4.Subtract the product, 4, from the new dividend, 4, which gives you a remainder of 0.Since there is no remainder anymore, the division is complete. The final quotient is 28.4. Therefore, 14.2 divided by 0.5 is equal to 28.4.

275 more people attended Saturday than Friday.
Which equation is in point-slope form for the given point and slope?
Answer: y-7 = 4(x+3), choice B
============================================
Point slope form is generally
y-y1 = m(x-x1)
we have m as the slope and (x1,y1) as the point this line goes through. In this case,
m = 4
(x1,y1) = (-3,7) so x1 = -3 and y1 = 7
So,
y-y1 = m(x-x1)
y - 7 = 4(x - (-3))
y - 7 = 4(x + 3)
which is why choice B is the answer
Point-slope form:
y - y₁ = m(x - x₁) "m" is the slope
Since you know:
m = 4
(x₁ , y₁) = (-3,7)
You can plug it into the equation
y - y₁ = m(x - x₁)
y - 7 = 4(x - (-3))
y - 7 = 4(x + 3)
Your answer is the 2nd choice

HELP!!!!!! I believe its B but I am not sure! :(
Answer:
A
Step-by-step explanation:
When solving for x as an exponent, we need to use logarithms in order to undo the operation and rearrange the terms. We use log rules to bring down the exponent and solve. Logarithms are the inverse operations to exponents and vice versa. We have one special kind of logarithm called the natural logarithm whose base is e. We write it as ln. Since our base is e here, we will use the natural logarithm to rearrange and isolate x.
[tex]e^{4x-1} =3[/tex]
We begin by applying the natural logarithm to each side.
[tex]ln(e^{4x-1}) =ln(3)[/tex]
Log rules allow use to rearrange the exponent as multiplication in front of the log.
[tex](4x-1)ln(e) =ln(3)[/tex]
ln e as an inverse simplifies to 1.
[tex](4x-1)(1)=ln(3)[/tex]
We now apply the inverse operations for subtraction and multiplication.
[tex]4x-1+1=1+ln(3)\\4x=1+ln(3)\\\frac{4x}{4} =\frac{1+ln3}{4} \\x =\frac{1+ln3}{4}[/tex]

Need help fast please
Answer:
13. The slope for a line that is perpendicular to the line y=4x+8 is -1/4
14. The slope for a line that is perpendicular to the line x=-6 is 0
15. The equation for a line that is perpendicular to the line 8x-4y=12 and passes through the origin is y = - (1/2) x
16. The equation for a line that is perpendicular to the line y=-(1/3)x and passes through the point (0,-10) is y=3x-10
Step-by-step explanation:
13. What is the slope for a line that is perpendicular to the line y=4x+8?
y=mx+b
Comparing with the form slope-intercept, the slope of the given line is the coefficient of x, then the slope of the given line is 4.
A line perpendicular to y=4x+8 must have a slope opposite and inverse, then:
Slope of the perpendicular = - 1/4
14. What is the slope for a line that is perpendicular to the line x=-6?
The line x=-6 is a vertical line. A line perpendicular to the line x=-6 must be a horizontal line (Angle=0°), then:
Slope of the perpendicular = tan Angle = tan 0° = 0
15. Write the equation for a line that is perpendicular to the line 8x-4y=12 and passes through the origin.
8x-4y=12
Isolating y: Subtracting 8x both sides of the equation:
8x-4y-8x=12-8x
-4y=-8x+12
Dividing all the terms by -4:
-4y/(-4)= -8x/(-4)+12/(-4)
y=2x-3
The slope of the given line is 2
The slope of the perpendicular is m=-1/2 (opposite and inverse to the slope of the given line)
The perpendicular passes through the origin:
P1=(0,0)=(x1,y1)→x1=0, y1=0
Using the equation point - slope:
y-y1=m(x-x1)
Replacing the known values:
y-0=(-1/2)(x-0)
y=(-1/2)x
16. Write an equation for a line that is perpendicular to the line y=-(1/3)x and passes through the point (0,-10).
The slope of the given line is -(1/3)
The slope of the perpendicular is m=3/1→m=3 (opposite and inverse to the slope of the given line)
The perpendicular passes through the point:
P1=(0,-10)=(x1,y1)→x1=0, y1=-10
Using the equation point - slope:
y-y1=m(x-x1)
Replacing the known values:
y-(-10)=3(x-0)
y+10=3x
Isolating y: Subtracting 10 both sides of the equation:
y+10-10=3x-10
y=3x-10

HELPP! Calculate S22 for the arithmetic sequence in which a12=2.4 and the common difference is d=3.4
Answer:
S22 for the arithmetic sequence is:
First option: 15.4
Step-by-step explanation:
a12=2.4
d=3.4
S22=?
Sn=(a1+an)n/2
n=22
S22=(a1+a22)22/2
S22=(a1+a22)11
ak=aj+(k-j)d
a12=a1+(12-1)d
2.4=a1+11(3.4)
2.4=a1+37.4
Solving for a1: Subtracting 37.4 both sides of the equation:
2.4-37.4=a1+37.4-37.4
Subtracting:
-35=a1
a1=-35
a22=a12+(22-12)d
a22=2.4+10(3.4)
a22=2.4+34
a22=36.4
S22=(a1+a22)11
S22=(-35+36.4)11
S22=(1.4)11
S22=15.4

In triangle LNP, R is the centroid and LO = 30. Find LR and RO. Enter the answers as numbers.
Answer:
[tex]|LR|=20[/tex]
[tex]|RO|=10[/tex]
Step-by-step explanation:
The centroid divides the median in the ratio [tex]2:1[/tex].
Thus [tex]|LR|:|RO|=2:1[/tex]
This implies that,
[tex]|LO|:|RO|=3:1[/tex]
We were given that,
[tex]|LO|=30[/tex]
We substitute this value to obtain,
[tex]30:|RO|=3:1[/tex]
or
[tex]\frac{30}{|RO|}=\frac{3}{1}[/tex]
We cross multiply to get,
[tex]3|RO|=30\times 1[/tex]
We divide through by 3, to get,
[tex]|RO|=10[/tex]
We can observe from the diagram that
[tex]|LR|+|RO|=|LO|[/tex]
[tex]|LR|+10=30[/tex]
[tex]|LR|=30-10[/tex]
[tex]|LR|=20[/tex]

What is an equation of the line that is parallel to y=4x-1 and that passes through the point (-3,5)?
A. y=4x-3
B. y=4x+5
C. y=4x+17
D. y=-4x+17
Answer:
C. y=4x+17
Step-by-step explanation:
If we want to find a line parallel to y =4x-1, the slopes will have to be the same because parallel lines have the same slope. Knowing y= mx+b we know the slope of the old line is 4, so the slope of the parallel line is 4.
If we know the slope of the line and a point, we can use the point slope form of a line
y-y1 = m(x-x1)

y-5+5 = 4x+12+5
y = 4x+17
Answer: The answer is C. y=4x+17

Ms.Rochelle wants to put her 29 students into groups of 6. How many groups of 6 can she make? If she puts any remaining students in a smaller group, how many students will be in that group?
Answer:
A. 4 groups of 6 students in each group.
B. The smaller group will have 5 students.
Step-by-step explanation:
We have been given that Ms.Rochelle wants to put her 29 students into groups of 6.
A. To find the number of groups of 6 that can be made from 29 students, we will find the greatest multiple of 6 from 29.
Multiples of 6 are: 6, 12, 18, 24, 30, 36,...
We can see that the greatest multiples of 6 in 29 in 24.
[tex]\text{Number of groups that can be made with 29 students}=\frac{24}{6}[/tex]
[tex]\text{Number of groups that can be made with 29 students}=4[/tex]
Therefore, Ms. Rochelle can form 4 groups from 29 students with 6 students in each group.
B. To find the number of students in small group, we will subtract 24 from 29.
[tex]\text{Number of students in the small group}=29-24[/tex]
[tex]\text{Number of students in the small group}=5[/tex]
Therefore, If Ms. Rochelle puts any remaining students in a smaller group, the number of students in smaller group will be 5.

The value of x is 12.
Answer: False
Step-by-step explanation:
45-45-90 is a special triangle because there is a specific relationship between the legs and the hypotenuse: a - a - a√2
So, If the leg of the 45-45-90 triangle is 12, then the hypotenuse (labeled as x in your drawing) will be 12√2.
A rectangular field is 115 yards long and 75 yards wide.
Give the length and width of another rectangular field that has the same perimeter but a smaller area
Final answer:
To create a rectangular field with the same perimeter but a smaller area than the original 115 yards by 75 yards field, one could have a field that is 130 yards long and 60 yards wide.
Explanation:
To find the length and width of another rectangular field that has the same perimeter as a 115 yards by 75 yards field but a smaller area, we first calculate the perimeter of the original field:
Perimeter = 2(length + width) = 2(115 yd + 75 yd) = 2(190 yd) = 380 yd
To have a smaller area, the new field cannot be a square (which would maximize the area) and the sides need to have a greater difference in their measurements while still adding up to half of the original perimeter:
Let's assume the new length is 130 yards, to find the new width: 380 yd / 2 - 130 yd = 60 yd
Therefore, a new rectangular field could be 130 yards long and 60 yards wide.
Which of the following points is a solution of the inequality y < -|x|?
A) (1, -2)
B) (1, -1)
C) (1, 0)
Answer: choice A only
(1,-2) is the only solution (from the list of choices)
====================================
Explanation:
Let's go through each answer choice. We'll plug the coordinates in one at a time.
-------------
Choice A has the point (1,-2) so x = 1 and y = -2 pair up together
y < -|x|
-2 < -|1|
-2 < -1
This is a true statement as -2 is to the left of -1 on the number line. So (1,-2) is one solution. Let's see if there are others.
-------------
Choice B) plug in (x,y) = (1,-1)
y < -|x|
-1 < -|1|
-1 < -1
False. A number is not smaller than itself. So we can cross B off the list.
-------------
Choice C) plug in (x,y) = (1,0)
y < -|x|
0 < -|1|
0 < -1
This is false because -1 is smaller than 0. Cross choice C off the list.
-------------
Only choice A is a solution point for this inequality. If we were to graph the inequality, we would see only point A is in the shaded region while the other points are outside the shaded region.
The dashed boundary line does not count as the shaded region. This visually confirms why point B does not work.
After evaluating each point against the inequality y < -|x|, only point A (1, -2) satisfies the condition, making it the correct answer.
Explanation:To determine which point is a solution for the inequality y < -|x|, we need to check if the y-value of each point is less than the negative absolute value of its corresponding x-value.
For point A (1, -2), we check if -2 < -|1|. Since |-1| = 1, we are checking if -2 < -1, which is true. So, point A is a solution.For point B (1, -1), we check if -1 < -|1|. Since |-1| = 1, we are verifying if -1 < -1, which is not true. Therefore, point B is not a solution.For point C (1, 0), we check if 0 < -|1|. Since |-1| = 1, we are verifying if 0 < -1, which is not true. Hence, point C is not a solution.Therefore, the correct answer is point A (1, -2), as it is the only point where the y-value is less than the negative absolute value of the x-value.
Ali caught a fish that weighted 9 and 1/2 lb. Lisa caught a fish that weighed 5 and 1/ 3 lb. How much more did ali fish weight.
Final answer:
Ali's fish weighs 25/6 lb more than Lisa's fish.
Explanation:
To find out how much more Ali's fish weighs compared to Lisa's fish, we need to subtract the weight of Lisa's fish from the weight of Ali's fish.
Ali's fish weighs 9 and 1/2 lb, which can be rewritten as 19/2 lb. Lisa's fish weighs 5 and 1/3 lb, which can be rewritten as 16/3 lb.
Now, subtracting the weight of Lisa's fish from Ali's fish, we have:
Ali's fish weight - Lisa's fish weight = (19/2) lb - (16/3) lb = (57/6) lb - (32/6) lb = 25/6 lb.
Therefore, Ali's fish weighs 25/6 lb more than Lisa's fish.
