Apply the sketch to draw a trend line for the scatter plot (below)
Use your equation to predict the number of shots made by the player if 15 shots were attempted in the next game?
Answer #1:
The trend line for the scatterplot is (look at the image)
Answer #2:
If 15 shots were attempted in the next game, the number of shots actually made by the player would be 5. The player made 5 total shots out of the 15.

Two highways meet at right angles in a town. Both highways are exactly straight
lines. Two cars leave the intersection at exactly the same time. One car starts traveling East
at 40mph and is decelerating at a rate of 1mph per hour. The other car starts traveling North
at 30mph and is accelerating at a rate of 0.5mph. At what rate is the distance between them
increasing 4 hours after they leave the intersection?
Answer:
Step-by-step explanation:
Using the relation :
S = ut + 1/2at²
S = distance
Car A :
Initial speed, u = 40 mph
a = negative acceleration = - 1 mph
At time, t = 4
S = 40(4) - 0.5(1)(4²)
S = 160 - 8
S = 152 miles
Car B :
Initial speed, u = 30 mph
a = acceleration = 0.5 mph
S = 30(4) - 0.5(1)(4²)
S = 120 - 8
S = 118 m
Change in distance / time
Rate of change = (152 - 118)m / 4 hours
Rate of change = 34 mi / 4 hr
Rate of change = 8.5 miles per hour

2 1/10
-2 1/1
-1 1/10
11/10
Answer:
Step-by-step explanation:
slope = m
m = y2-y1 / x2 - x1
m = (-4) - 7 / (-6) - (-4)
m = -11 / (-6) + 4
m = -11 / -2
m = 11/2

What is the measure of angle D
Answer:
52 degrees
Step-by-step explanation:
A triangle's angles all add up to 180 degrees so we can create this equation:
x + 20 + 3x + 32 = 180
Combine like terms.
x + 3x + 20 + 32 = 180
4x + 52 = 180
Subtract 52 from both sides.
4x = 128
Divide.
128 / 4 = 32
x = 32
Plug in the value of x.
x + 20
32 + 20
52
Angle D is equal to 52 degrees.

2. ALMN and APMN are shown below. What additional information is necessary to prove
ALMN = APMN by HL?
Help please!!!
Answer:
The additional information necessary is option;
D. [tex]\overline {MN}[/tex] ⊥ [tex]\overline {LP}[/tex]
Step-by-step explanation:
From the given figure, we have;
Given that ML ≅ MP,
The Hypotenuse Leg HL theorem of congruency is used to prove that a given number of right triangles based on the lengths of their hypotenuse and one of the legs. It states that two or more right triangles are congruent if they have equal lengths of both their corresponding hypotenuse side and one leg
To prove that ΔLMN and ΔPMN are congruent by HL, we will also be required to prove that ΔLMN and ΔPMN are right triangles
For ΔLMN and ΔPMN to be right triangles, the angles, ∠LNM and ∠PNM should be right angles = 90°
With ∠LNM = ∠PNM = 90°, then, line [tex]\overline {MN}[/tex] is perpendicular to line [tex]\overline {LP}[/tex] or [tex]\overline {MN}[/tex] ⊥ [tex]\overline {LP}[/tex]
Therefore, the additional information necessary to prove that ΔLMN ≅ ΔPMN by HL is [tex]\overline {MN}[/tex] ⊥ [tex]\overline {LP}[/tex].
Which two of the following numbers are rational?
1/3
.10
.π
√2
Answer:
1/3, 0.10
Step-by-step explanation:
Rational numbers can be expressed as a fraction of two integers.
1/3 is rational. When it is expressed as a fraction, it's 1/3. 1 is an integer, and 3 is an integer
0.10 is rational. It can be rewritten to be expressed as the fraction 1/10; 1 is an integer, and 10 is an integer.
.[tex]\pi[/tex] is irrational, because when expressed as a fraction, it is 1/[tex]\pi[/tex]. 1 is an integer, but [tex]\pi[/tex] is not. Both numbers need to be integers in order to be rational. Therefore, it is irrational
√2 is irrational. When expressed as a fraction, it's √2/1. √2 is not an integer. 1 is an integer. However, both numbers have to be integers in order to be rational. Therefore, √2 is not rational.

Identify the horizontal and vertical intercepts of the limacon represented by the equation r=4-6 sin theta.
Answer:
Vertical intercepts: (-2,pi/2) and (-10,pi/2)
Horizontal intercepts: (4,0) and (-4,0)
Step-by-step explanation:
I took the test and got it right.
The required horizontal intercepts are at approximately (41.81°, 0) and (138.19°, 0), and the vertical intercepts are at (0, 4) and (0, -10).
What is the intercept in the equation?In the equation intercept is the value of the linear function where either of the variables is zero.
To find the horizontal intercept(s) of the limacon, we need to set r equal to zero and solve for theta.
r = 4 - 6sin(Ф)
0 = 4 - 6sin(Ф)
6sin(Ф) = 4
sin(Ф) = 4/6
sin(Ф) = 2/3
We can use an inverse sine function to find the value of theta:
Ф= sin^-1(2/3)
Ф≈ 41.81° or 138.19°
These are the values of theta where the limacon crosses the x-axis (horizontal intercepts).
To find the vertical intercept(s), we need to set theta equal to zero or pi and solve for r.
When Ф= 0:
r = 4 - 6sin(0)
r = 4
So the limacon intercepts the y-axis at (0, 4).
When Ф= pi:
r = 4 - 6sin(pi)
r = 10
So the limacon intercepts the y-axis at (0, -10).
Therefore, the horizontal intercepts are at approximately (41.81°, 0) and (138.19°, 0), and the vertical intercepts are at (0, 4) and (0, -10).

triangular pyramid
square pyramid
triangular prism
cube
Answer:
cube
Step-by-step explanation:
The shape in the middle of the two rectangular prism would be a cube. This is the case since the angle at the base of the rectanglular prism forms a 90-degree angle. This indicates that the line is a straight line and would also form a 90-degree angle with the bottom angles as well. This would ultimately indicate that it forms a square, and since the shape is a 3-Dimensional shape it would be classified as a cube in this image.
Answer:
Triangular Prism

The factors of 18 are: 1, 2, 3, 6, 9, 18
The factors of 24 are: 1, 2, 3, 4, 6, 8, 12, 24
The factors of 40 are: 1, 2, 4, 5, 8, 10, 20, 40
Then the greatest common factor is 2.
The greatest common factor of 18 , 24 and 40 is HCF = 2
What is HCF and LCM?The Greatest Common Divisor GCF or the Highest Common Factor HCF is the highest number that divides exactly into two or more numbers. It is also expressed as GCF or HCF
Least Common Multiple (LCM) is a method to find the smallest common multiple between any two or more numbers. A common multiple is a number which is a multiple of two or more numbers
Product of HCF x LCM = product of two numbers
Given data ,
Let the HCF be represented as H
Let the first number be represented as p
Now , the value of p = 18
Let the second number be represented as q
Now , the value of q = 24
Let the third number be represented as r
Now , the value of r = 40
And , the factors of 18 = 1, 2, 3, 6, 9 and 18
The factors of 24 = 1, 2, 3, 4, 6, 8, 12 and 24
The factors of 40 = 1, 2, 4, 5, 8, 10, 20 and 40
So , the HCF of 18 , 24 and 40 is the number 2
Hence , the HCF is 2

4x+5y=60. what is the x and y intercepts? show work pls!!
Answer: (4,5)
Because I don't know another way I can solve
Step-by-step explanation:
Answer:
x-intercept: (15, 0)
y-intercept: (0, 12)
Step-by-step explanation:
1.) convert the equation to y=mx+b format
4x + 5y= 60
5y = -4x + 60
y = -4/5x + 12
2.) Now we know that "b" in the equation is the y-intercept. 12 is b so the y-intercept is 12.
3.) To find x intercept we will plug in y=0.
0 = -4/5x + 12
-12 = -4/5x
15 = x

The area of trapezium shaped field is 480 square meter, the distance between two parallel sides is 15m and one of the parallel side is 20m. Find the other parallel side
Answer: 44 m
Step-by-step explanation:
Given
The area of the trapezium is [tex]A=480\ m^2[/tex]
Distance between parallel sides [tex]h=15\ m[/tex]
One of the parallel sides is [tex]20\ m[/tex]
