Answer:
g(x) has the greatest y-intercept (the graph)
Step-by-step explanation:
The y-intercept for f(x) is -1, we can easily identify it at the end of the function.
The y-intercept for g(x) is 2, we can see that's where it crosses the y-axis.
The y-intercept for h(x) is 1, we can find this by substituting 0 for x in the equation.
h(0) = cos(0+2[tex]\pi[/tex])
h(0) = cos(2[tex]\pi[/tex])
h(0) = cos(360)
h(0) = 1
[tex]\pi[/tex] = 180 when converting degrees to radians, and you can find the cosine of 360 with a calculator.
The function with the greatest y-intercept is g(x).
How to know which function has the greatest y-intercept?Here we have the two functions:
f(x) = 4x - 1h(x) = cos(x + 2π).g(x) = tangent function with y-intercept at (0, 2)The y-intercept is the value of the function when we evaluate in x = 0, so the y-intercepts of the given functions are:
f(0) = 4*0 - 1 = -1
h(0) = cos( 0+ 2π) = 1
And for g(x), we know that the y-intercept is at y = 2.
Then we can see that the function g(x) has the greatest y-intercept.

A right angle triangle has sides whose lengths are $2$-digit integers. The digits of the length of the hypotenuse are the reverse of the digits of the length of one of the other sides. Determine the smallest possible length of the hypotenuse.
Answer:
Smallest possible length of the hypotenuse = 65
Step-by-step explanation:
Given - A right angle triangle has sides whose lengths are $2$-digit integers. The digits of the length of the hypotenuse are the reverse of the digits of the length of one of the other sides.
To find - Determine the smallest possible length of the hypotenuse.
Proof -
The possible Pythagoras triplets of a right angled triangle with 2 digit integers are -
(11, 60, 61)
(12, 35, 34)
(13, 84, 85)
(16, 63, 65)
(20, 21, 29)
(28, 45, 53)
(33, 56, 65)
( 36, 77, 85)
(39, 80, 89)
(48, 55, 73)
(65, 72, 97)
But, Here Given that
The digits of the length of the hypotenuse are the reverse of the digits of the length of one of the other sides.
So, There is only one possibility that satisfy the condition.
and that is, (33, 56, 65)
So, we get
Length of one side = 33
Length of second side = 56
Length of hypotenuse = 65
So,
Smallest possible length of the hypotenuse = 65

Answer:
456.73 cm²
Step-by-step explanation:
Area of a circle = πr²
The radius of the hub cap
= 75.74÷3.14÷2
= 12.06 cm (rounded to the nearest hundredth)
The area of the hub cap
= 3.14 × 12.06²
= 456.7314968152...
= 456.73 cm² (rounded to the nearest hundredth)
Circumference means the perimeter of a circle. So if the perimeter of a shape is smaller, it makes the shape turn out to be smaller.
So the area of the hub cap will be smaller.

A recent estimate by a large distributor of gasoline claims that 60% of all cars stopping at their service stations chose unleaded gas and that super unleaded and regular were each selected 20% of the time. In order to check the validity of these proportions, a study was conducted of cars stopping at the distributor's service stations in a large city. The results were as follows:
Gasoline Selected
Regular Unleaded Super Unleaded
51 261 88
Carry out a significance test of the distributors claim
Answer:
We reject the null hypothesis and conclude that at least 2 proportions differ from the stated value.
Step-by-step explanation:
There are 3 types of gas listed in the question.
Thus;
n = 3
DF = n - 1
DF = 3 - 1
DF = 2
Let's state the hypotheses;
Null hypothesis; H0: P_regular = P_super unleaded = 20%; P_i leaded = 60%
Alternative hypothesis; Ha: At least 2 proportions differ from the stated value.
Observed values are;
Regular gas; O = 51
Unleaded gas; O = 261
Super Unleaded; O = 88
Total observed values = 51 + 261 + 88 = 400
We are told that super unleaded and regular were each selected 20% of the time and that unleaded gas was chosen 60% of the time.
Thus, expected values are;
Regular gas; E = 20% × 400 = 80
Unleaded gas; E = 60% × 400 = 240
Super Unleaded; E = 20% × 400 = 80
Formula for chi Square goodness of fit is;
X² = Σ[(O - E)²/E]
X² = (51 - 80)²/80) + (261 - 240)²/240) + (88 - 80)²/80)
X² = 13.15
From the chi Square distribution table attached and using; DF = 2 and X² = 13.15, we can trace the p-value to be approximately 0.001
Also from online p-value from chi Square calculator attached, we have p to be approximately 0.001 which is similar to what we got from the table.
Now, if we take the significance level to be 0.05, it means the p-value is less than it and thus we reject the null hypothesis and conclude that at least 2 proportions differ from the stated value.

A research study comparing three treatments with n= 5 in each treatment produces T1= 5, T2= 10, T3= 15, with SS1= 6, SS2= 9, SS3=9, and EX= 94. For this study, what is SSbetween
Answer:
SSbetween is 10
Step-by-step explanation:
Given the data in the question;
A research study comparing three treatments with n = 5 in each treatment produce;
that is: n₁ = 5, n₂ = 5, n₃ = 5
T₁ = 5, T₂ = 10, T₃ = 15,
SS₁ = 6, SS₂ = 9, SS₃ = 9
∑x² = 94
First, we obtain the grand total;
G = T₁ + T₂ + T₃ = 5 + 10 + 15 = 30
N = n₁ + n₂ + n₃ = 5 + 5 + 5 = 15
Total SS = ∑x² - ( G²/N )
we substitute
Total SS = 94 - ( (30)²/ 15 )
Total SS = 94 - ( 900 / 15 )
Total SS = 94 - 60
Total SS = 34
To get the SSbetween or Between SS;
Between SS = ∑( T²/n ) - ( G²/N )
Between SS = ∑( (5)²/5 + (10)²/5 + (15)²/5 ) - ( (30)²/ 15 )
Between SS = ∑( 25/5 + 100/5 + 225/5 ) - ( 900 / 15 )
Between SS = ∑( 5 + 20 + 45 ) - 60
Between SS = 70 - 60
Between SS = 10
Therefore, SSbetween is 10

it takes electricians 36 days to wire a new housing subdivision. how many days would 32 electricians take to do the same job?
Answer:
The 32 electricians will take 1 day and 3 hours to complete the wiring.
Step-by-step explanation:
Since it takes electricians 36 days to wire a new housing subdivision, to determine how many days would 32 electricians take to do the same job the following calculation must be performed:
36/32 = X
1.125 = X
1 = 24
0.125 = X
0.125 x 24 = X
3 = X
Therefore, the 32 electricians will take 1 day and 3 hours to complete the wiring.

Your family's new business is finally starting to get on track. You started with an investment of $20,000, but lost 10% the first year, 6% the second year, and 3$ the third year. During the fourth year, however, you gained 5%
(A) How much money did you have after the first three years?
(B) What was the cumulative decay factor after the first three years?
(C) What was the cumulative factor after the first four years? Does this factor represent decay or growth?
(D) What percent increase do you need to get during the fifth year to break even (end up with $20,000)?
Answer:
A)
$16412.40.
B)
Our culminate decay factor was 0.82062.
C)
0.861651. It represents decay because it's less than one.
D)
We need at least a 16.1% increase.
Step-by-step explanation:
We started off with $20,000. In the first year, we lost 10%. In the second year, we lost an additional 6%, and another 3% in the third year. During the fourth year, however, we regained 5%.
Part A)
In the first year, we lost 10% of our original investment. In other words, we will have left 100% - 10% or 90% of our original investment. So, after the first year, we will have:
[tex]20000(0.9)=\$ 18000[/tex]
During the second year, we lost another 6%. So, it will be 100% - 6% = 94% = 0.94 of our current investment. So, after the second year, we will have:
[tex]18000(0.94)=\$ 16920[/tex]
Finally, during the third year, we lost 3%. So, it will be 100% - 3% = 0.97 of our current investment:
[tex]16920(0.97)=\$ 16412.4[/tex]
After the first three years, our investment dwindled down to $16412.40.
Part B)
We started off with $20,000 and ended up with $16412.40. Let r represent the decay factor. We can write the following equation:
[tex]20000d=16412.4[/tex]
This reads, "our original investment of $20,000 by multiplied by some (decay) factor equals our current investment of $16412.4."
Solve for d:
[tex]\displaystyle d=\frac{16412.4}{20000}=0.82062[/tex]
So, our decay factor is 0.82062.
(Note: This means that our rate of decay was 1 - 0.82062 = 0.17938. So, we lost approximately 18% of our investment over the course of the three years.)
Part C)
After the third year, our investment was $16412.40.
During the fourth year, we gained 5% on our investment. So, it will be 100% + 5% = 105% = 1.05 of our current investment:
[tex]16412.4(1.05)=\$ 17233.02[/tex]
Again, we can write an equation:
[tex]20000d=17233.02[/tex]
Where d represents the culminative factor after four years.
Solving for d yields:
[tex]d=0.861651[/tex]
Since the culminative factor is less than one, this is decay.
Decay is also correct contextually, since after four years, our current investment is lower than our original investment.
Part D)
After the fourth year, we have $17233.02.
In order to find the percent increase to rereach $20,000, we can write an equation:
[tex]17233.02d=20000[/tex]
Solving for d yields:
[tex]\displaystyle d\approx 1.1606[/tex]
So, the growth factor is about 1.1606.
This means that during the fifth year, we will need to grow by 1 - 1.1606 or about 16.1% in order to rereach our original investment of $20,000.

Given f(x) = x + 1 and g(x) = x^2, what is (g o f) (x)?
A. (g o f) (x) = x^2+x+1
B. (g o f) (x) = x^2+1
C. (g o f) (x) = (x + 1)^2
D. (g o f) (x) = x^2(x + 1)
Answer:(g o f)(x)=x^2+x+1
Step-by-step explanation:
It is Given f(x) = x + 1 and g(x) = x^2 therefore, the function (g o f) (x) is x^2 + x + 1.
What is function of functions and how are they represented?The function of function, as the name suggests, is functions applied over functions themselves. This is also called function composition.
We have input. We apply one function on that input. Then we apply another function on the output obtained by the first function. This whole function application on the first input is called the function of functions.
The resultant function which maps the input x to the final output is called the function of a function.
If the first function is g( and the other function is f, then we can write the resultant function of the function as
[tex](f\circ g)(x)[/tex]
where the x is the input to the first function.
Thus, we have;
[tex](f\circ g)(x) = f(g(x))[/tex]
It is Given f(x) = x + 1 and g(x) = x^2, we need to find (g o f) (x)
(g o f)(x) = g(x) + f(x)
= x^2 + x + 1
