Answers
Answer:
54
Step-by-step explanation:
Given f(x) = 6(1 - x), what is the value of f(-8)?
F(-8)=6(1--8) -- plug -8 into f(x) and x spots.
F(-)8=6(9) ---then solve
F(-8)=54 --- so the function to f(-8) is 54

write answer is 600,, 100% sure
Lol , so this question is from your school google forms? ; )
Answer is 600. Lemme show you how.
Y is proportional to x.
y ∝ x
to remove proportionality , we put k.
y = kx
Now , insert values of y and x to find k.
60 = k *75
k = 75 / 60
Now when Y = 480 , x =?
x = (75/60)(480) = 600.
X = 600
A 2nd baseman throws a baseball toward the 1st baseman 60 feet away. The path of the ball is given by f(x)=-0.004x^2+0.3x+6, where f(x) is the height of the ball (in feet) and x is the horizontal distance from the 2nd baseman (in feet). The 1st baseman can reach 8 ft high. Can the 1st baseman catch the ball without jumping?
Answers
Answer:
The 1st baseman can't catch the ball without jumping.
Step-by-step explanation:
To know if the 1st baseman can catch the ball without jumping we need to find the height reached by the baseball by solving the following equation:
[tex] f(x) = -0.004x^{2} + 0.3x + 6 [/tex]
We know that x (the horizontal distance) = 60 feet, so we have:
[tex] f(60) = -0.004(60)^{2} + 0.3(60) + 6 [/tex]
[tex]f(60) = 9.6 ft[/tex]
Since the 1st baseman can reach 8 ft high and the height reached by the baseball is 9.6 ft, the 1st baseman can't catch the ball without jumping.
Therefore, the 1st baseman can't catch the ball without jumping.

Robert bought 3 baseball caps for the same amount and 1 baseball jersey that cost $45. Without tax, the total cost of the items is $90. What is the cost of each baseball cap?
Answers
Answer:
Unitary cost= $15
Step-by-step explanation:
First, we need to calculate the total cost of the baseball caps:
Total cost baseball caps= 90 - 45
Total cost baseball caps= $45
Now, the unitary cost of each baseball caps:
Unitary cost= total cost / number of units
Unitary cost= 45/3
Unitary cost= $15

The sum of a numerator and denominator of a fraction is 18. If the denominator increased by 2, the fraction reduces to 1/3. Find the fraction.
Answers
Sum of the numerator and denominator = 18
If the denominator is increased by 2 , the fraction reduces to 1/3.
Find:the fraction
Solution:Let the fraction be x/y.
⟹ x + y = 18
⟹ x = 18 - y -- equation (1)
And,
If the denominator is increased by 2 , the fraction reduces to 1/3.
⟹ x/y + 2 = 1/3
⟹ 3x = y + 2
Substitute the value of x from equation (1).
⟹ 3(18 - y) = y + 2
⟹ 54 - 3y = y + 2
⟹ 54 - 2 = y + 3y
⟹ 52 = 4y
⟹ 52/4 = y
⟹ 13 = y
Substitute the value of y in equation (1).
⟹ x = 18 - 13
⟹ x = 5
Therefore, the required fraction x/y is 5/13.
I hope it will help you.

Answer:
Length is twice the breadth.
→ Length = 2 * x = 2x m.
Also,
Perimeter of the field = 150 m.
We know that,
Perimeter of a rectangle = 2(length + breadth).
Hence,
→ 150 = 2(x + 2x)
→ 150 = 2 * 3x
→ x = 150/2 * 3
→ x = 25

If the population standard deviation of the stopping distance is provided as σ = 6.7 feet. Estimate the average stopping distance of all Model A tires with a 94% confidence interval.
Answers
Complete Question
The complete question is shown on the first and second uploaded image
Answer:
The estimate of the average stopping distance of all model A tires with a 94% confidence interval is
[tex]132.94 < \mu < 144.86[/tex]
Step-by-step explanation:
From the question we see that
The sample size is n = 8
The population standard deviation is [tex]\sigma = 6.7[/tex]
Generally the sample mean is mathematically represented as
[tex]\= x = \frac{\sum x_i }{n}[/tex]
=> [tex]\= x = \frac{ 145 + 152 + \cdots + 133}{8}[/tex]
=> [tex]\= x = 138.9[/tex]
From the question we are told the confidence level is 95% , hence the level of significance is
[tex]\alpha = (100 - 94 ) \%[/tex]
=> [tex]\alpha = 0.04[/tex]
Generally the degree of freedom is mathematically represented as
[tex]df = n - 1[/tex]
=> [tex]df = 8 - 1[/tex]
=> [tex]df = 7[/tex]
Because the n < 30 we will making use of the t table
Generally from the t distribution table the critical value of [tex]\frac{\alpha }{2}[/tex] at a degree of freedom of [tex]df = 7[/tex] is
[tex]t_{\frac{\alpha }{2}, 7 } = 2.517 [/tex]
Generally the margin of error is mathematically represented as
[tex]E = t_{\frac{\alpha }{2} , df} * \frac{\sigma }{\sqrt{n} }[/tex]
=> [tex]E = 2.517 * \frac{6.7 }{\sqrt{8} }[/tex]
=> [tex]E =5.96 [/tex]
Generally 94% confidence interval is mathematically represented as
[tex]\= x -E < \mu < \=x +E[/tex]
=> [tex]138.9 -5.96 < \mu < 138.9 + 5.96[/tex]
=> [tex]132.94 < \mu < 144.86[/tex]

A designer is trying to build the ideal sized fish tank for a customer. It must hold exactly 24 cubic feet of water and can only be 4 feet in height. If the designer increases the width of the fish tank, what must happen to the length of it so that the volume remains the same? A. The length must stay the same. B. The length must decrease. C. The length must increase.
Answers
Answer:
B. The length must decrease
Step-by-step explanation:
Given;
maximum volume of the tank, V = 24 ft³
maximum height of the tank, h = 4 ft
let the width of the tank = w
let the length of the tank = L
Volume of the tank is given by;
V = Lwh
L = V / (hw)
L = 24 / (4w)
L = 6/w
L is inversely proportional to w; an increase in w (width) will cause a decrease in L (length)
Therefore, If the designer increases the width of the fish tank, "The length must decrease"

Given, x and y are inversely proportional.
So, the equation is xy=k, where k is the constant of proportionality
x=4, y=9. plug in the values to find k.
k=4*9 = 36
When x=3, y = k/x =36/3 = 12
