The table below gives the stopping distance y (in 100 meters) for a train traveling on a track at various speeds x (miles per hour).
Speed, x (mi/h) 50 55 60 65 70 75 80 85 90
Distance ,y (100m) 20 25 35 50 70 95 125 200 160
Required:
Find an equation of the quadratic function that models the data, and predict the stopping distance for the train traveling at 95 miles per hour.
The required equation is 0.1x²-9.5x+245=0
And, the stopping distance for the train traveling at 95 miles per hour is 245.
What is function?Function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable.
Here, given that,
Speed, x (mi/h) 50 55 60 65 70 75 80 85 90
Distance ,y (100m) 20 25 35 50 70 95 125 160 200
Now, let an quadratic equation be, ax²+bx+c=y
Putting the values of x & y we get,
2500a+50b+c=20 ....(1)
3025a+55b+c=25...(2)
3600a+60b+c=35 .....(3)
solving this we get,
a= 0.1
b=-9.5
c=245
Hence, the required equation is 0.1x²-9.5x+245=0
And, the stopping distance for the train traveling at 95 miles per hour is 245.

Find the measures of the numbered angles in the figure, shown to the right. Name the theorem that justifies each
answer.
M<1=
M<2=
M<3=
M<4=
Answer:
Step-by-step explanation:
m∠1 + 75° = 180° [Linear pair of angles]
m∠1 = 180° - 75°
= 105°
m∠2 = m∠1 [Opposite angles of a rectangle are equal]
m∠2 = m∠1 = 105°
m∠2 = m∠3 = 105° [Vertically opposite angles]
m∠3 = m∠4 = 105° [Corresponding angles]
Therefore, all four angles measure the same as 105°.

The linear functions f(x) and g(x) are represented on the graph, where g(x) is a transformation of f(x):
A graph with two linear functions; f of x passes through 1, 3 and 3, 13, and g of x passes through negative 1, 3 and 1, 13.
Part A: Describe two types of transformations that can be used to transform f(x) to g(x). (2 points)
Part B: Solve for k in each type of transformation. (4 points)
Part C: Write an equation for each type of transformation that can be used to transform f(x) to g(x). (4 points)
Part A:
I only see one thing that you can do. You can use transformation to move f(x) 6 units to the left
Part B:
g(x) = f(x)+1 where k = 1, and g(x) = f (x + 8) where k = 8
Part C:
g(x) = f (x) + 1, and g(x) = f (x + 8)

The population of bluegills (type of fish) has a mean length of 152.09mm and a standard deviation of 19.62mm. What is the probability that a random sample of 25 fish has a mean length of 140mm or shorter
Answer:
0.001035
Step-by-step explanation:
Mean (m) = 152.09 mm
Standard deviation (σ) = 19.62 mm
Sample size (n) = 25
Length being 140mm or shorter (x) : x ≤ 140
Using the Zscore relation :
Zscore = (x - m) / (σ/√n)
Zscore = (140 - 152.09) / (19.62/√25)
Zscore = (140 - 152.09) / (19.62/5)
Zscore = −3.081039
P(Z ≤ −3.08) = 0.001035

The Pappas family has two cats, Zeus and Athena. Together they weigh thirteen pounds. Zeus weighs 5 pounds less than Athena. How much does Athena weigh?
Given:
Combine weight of two cats, Zeus and Athena = 13 pounds
Zeus weighs 5 pounds less than Athena.
To find:
The weight of Athena.
Solution:
Let x pounds be the weight of Athena.
Zeus weighs 5 pounds less than Athena.
Weight of Zeus = x - 5 pounds
Combine weight of two cats, Zeus and Athena = 13 pounds
[tex]x+(x-5)=13[/tex]
[tex]2x-5=13[/tex]
Add 5 on both sides.
[tex]2x=13+5[/tex]
[tex]2x=18[/tex]
Divide both sides by 2.
[tex]x=\dfrac{18}{2}[/tex]
[tex]x=9[/tex]
Therefore, the weight of Athena is 9 pounds.

1-3 Function Operations and Composition Jim was given three functions and asked to determine f + (gon). The functions were f (x) = x2 g(x) = 3x + 1, and h(x) = 2x. Jim started by writing the problem as (r + (gon))(x) = x2 + 2(3x + 1). What was Jim's mistake? What is the correct solution? O A Jim omitted the x in h(x): [ + (g = n)) = 7x2 + 2x B. Jim should have added f and g first; ( + (gon)) = 4x2 + 6x + 1 O C. Jim incorrectly performed h og instead of goh: (f + g - h)) = x2 + x + 1. OD D. Jim did not follow the order of operations, I + (g o h)) = x2 + 6x + 2.
Answer:
Step-by-step explanation:
Given the functions:
f (x) = x^2
g(x) = 3x + 1
h(x) = 2x
We are to look for f + (goh)
First we need to get the composite function goh
goh = g(h(x))
g(h(x)) = g(2x)
To get g(2x) we will substitute x in g(x) as 2x as shown below:
Given g(x) = 3x+1
g(2x) = 3(2x)+1
g(2x) = 6x+1
f + goh = x² + (6x +1)
f + goh = x² + 6x +1
Jim wrote goh as 2(3x+1) instead of 3(2x) + 1. The composite function that Jim looked for was hog not goh.
The correct solution is f + goh = x² + 6x +1

b. What is the probability that no employees were promoted?
c. Find the value of the expected value and the variance of this distribution.
Answer:
a)0.764
b)0.116
c)Expected value =1.75
Variance=1.1375
Step-by-step explanation:
Total Number of employees = 20
Number of promotions awarded = 7
Probability of success p =[tex]\frac{7}{20}[/tex]
Probability of failure q = [tex]1-\frac{7}{20}=\frac{13}{20}[/tex]

We will use binomial
[tex]P(X=x)=^nC_r p^r q ^{n-r}\\P(X\leq 2)=P(X=0)+P(X=1)+P(X=2)\\P(X\leq 2)=^{5}C_0 (\frac{7}{20})^0 (\frac{13}{20})^{5-0}+^{5}C_1 (\frac{7}{20})^1 (\frac{13}{20})^{5-1}+^{5}C_2 (\frac{7}{20})^2 (\frac{13}{20})^{5-2}\\P(X\leq 2)=\frac{5!}{0!(5-0)!} (\frac{7}{20})^0 (\frac{13}{20})^{5-0}+\frac{5!}{1!(5-1)!}(\frac{7}{20})^1 (\frac{13}{20})^{5-1}+\frac{5!}{2!(5-2)!} (\frac{7}{20})^2 (\frac{13}{20})^{5-2}\\P(X\leq 2)=0.764[/tex]
b)What is the probability that no employees were promoted?
[tex]P(X=0)=^{5}C_0 (\frac{7}{20})^0 (\frac{13}{20})^{5-0}\\P(X=0)=\frac{5!}{0!(5-0)!} (\frac{7}{20})^0 (\frac{13}{20})^{5-0}\\P(X=0)=0.116[/tex]
c)
[tex]E(X)=np=5 \times (\frac{7}{20})=1.75\\Var(X)=npq=5 \times (\frac{7}{20}) \times \frac{13}{20}=1.1375[/tex]

A red ball rolls for 6 meters across a sticky level surface and slows down to a stop. the ball was rolling at 36 meters per second when it began to roll across the sticky surface. find the acceleration, velocity final, the velocity initial, the velocity average, the distance the ball rolled, and the time of the balls roll across the sticky surface
Answer:
Please find the answer in the explanation
Step-by-step explanation:
Given that a red ball rolls for 6 meters across a sticky level surface and slows down to a stop. the ball was rolling at 36 meters per second when it began to roll across the sticky surface. To find the acceleration, let us use third equation of motion
V^2 = U^2 + 2as
As the object is moving to stop, V = 0
0 = U^2 - 2as
36^2 = 2 × a × 6
1296 = 12a
a = 1296 / 12
a = 108 m/s
The velocity final = 0
The velocity initial = 36 m/s
the velocity average = (36 + 0)/2
Average velocity = 36/2 = 18m/s
the distance the ball rolled = 6m
and the time of the balls roll across the sticky surface will be achieved by using first equation of motion
V = U + at
V = 0
0 = 36 - 108t
108t = 36
t = 36 / 108
t = 0.3 seconds
