The formula for the volume of a cylinder is as follows, where V is the volume of the cylinder, r is the radius of the base, and l is the length of the cylinder.
V=\pi r^2lV=πr
2
l
Solve for l in terms of V and r then find the length of a cylinder that has a volume of 1256 cubic inches and whose base has a radius of 7 inches. Round your answer to the nearest tenth of an inch; use 3.14 for π.
Answer:
8.2 inStep-by-step explanation:
Volume formula:
V = πr²lSolving for l:
l = V/(πr²)Length of the given cylinder:
l = 1256/(π7²) = 1256/(3.14*49) = 8.2 in rounded8.2 in is the correct answer to the question

Consider the equation 2(3x + 4) = ax + b
Part 1
Find one value for a and one value for b so that the equation has infinitely many solutions.
For the value of a you determined above what is the value for b so that the equation has infinitely many solutions
Support your answer. Explain your reasoning
Part 2
Find one value for a and one value for b so that the equation has no solution.
Find the value of a you determined above what is the value for b so that the equation has no solution.
Support your answer explain your reasoning.
Answer:
Let's solve for a.
2(3x+4)=ax+b
Step 1: Flip the equation.
ax+b=6x+8
Step 2: Add -b to both sides.
ax+b+−b=6x+8+−b
ax=−b+6x+8
Step 3: Divide both sides by x.
ax
x
=
−b+6x+8

a=

What is the major difference between mutual funds and certificates of deposit? How are mutual funds and certificates of deposit alike? What is the major difference in bonds and treasury notes, and which would you prefer as an investor? How are bonds, treasury notes, mutual funds alike?
Answer:
Mutual funds differ from CDs in a multitude of ways. Mutual funds are diversified portfolios of stocks and bonds managed by a financial advisor or broker. They typically offer substantially higher returns than CDs, and while they are riskier than CDs, they are not considered high risk investments.

In the context of a hypothesis test for two proportions, which of the following statements about the pooled sample proportion, , is/are true? I. It estimates the common value of p1 and p2 under the assumption of equal proportions. II. It is obtained by averaging the two sample proportions 1 and 2. III. It is equal to the proportion of successes in both samples combined.
Answer:
The statements that are true about a hypothesis test for two proportions are:
I. It estimates the common value of p1 and p2 under the assumption of equal proportions.
II. It is obtained by averaging the two sample proportions 1 and 2.
Step-by-step explanation:
We use the two sample proportion z-test to determine whether the proportions of the two groups differ. This test calculates the range of values that is likely to include the differences between the sample proportions of p1 and p2.
A researcher comparing the means of dependent samples consisting of 30 matched pairs and obtained a mean difference of 5 and a standard error of the mean difference of 2. The confidence interval for the mean difference was (1.6, 8.4). What confidence level was used in constructing the interval
Answer:
91.08%
Step-by-step explanation:
Confidence interval = (1.6, 8.4)
Sample size (n) = 30
Standard Error (E) = 2
Mean (m) = 5
The confidence interval is obtained using the relation :
Mean ± Zcritical * standard error
5 ± Zcritical * 2
5 - (Zcritical * 2) = 1.6
5 - 2Zcritical = 1.6
5 - 1.6 = 2Zcritical
3.4 = 2Zcritical
Zcritical = 3.4 / 2
Zcritical = 1.7
From Z probability calculator
P(Z < 1.7) = 0.044565
α = 1 - (0.044565 * 2) = 0.91087
0.91087 * 100% = 91.08% = 91%
Hence, confidence level = 91.08%

1. Is an arithmetic sequence a function?
Sometimes, it depends on the arithmetic sequence.
Yes, always.
Not enough information is given.
No, never
Yes, always.
A sequence is a function that takens a positive integer and maps it some other number. For any integer you plug into the sequence, you only ever get one output.

Is (x + 5) a factor of f(x) = x3 − 4x2 + 3x + 7?
Answer:
no
Step-by-step explanation:
here, f (x)=x^3 - 4x^2 + 3x + 7
when, factor is (x + 5)
x - a =x + 5
a = -5
Reminder= f (a)
= (-5)^3 - 4 (-5)^2 + 3×(-5) + 7
= -233
Since Reminder = -233 which is not 0 .
(x + 5) is not a factor of f (x)=x3-4x2+3x+7

- 13x + 9
Which is the correct answer?
A. Function f is both even and odd
B. Function F is odd
C. Function f is neither even or odd
D. Function f is even
(Please explain your answer)
Answer:
B. Function F is odd
Step-by-step explanation:
If a function is odd, then -f(x) = f(-x), for all values of x.
For such function an origin symmetry is obtained just like the image uploaded.
Also, for such function, there is an equal distance between f(x) and f(-x), just like the image uploaded (d₁ = d₂).
Thus, the correct option is "B"
Sin(0)= cos(6) what is the value of 0?
We need to find Ο for : sin(Ο)= cos(6)
We know that:
cos θ =sin (90 - θ), so if we call θ = 6 then O will be:
O = 90 - θ
O = 90 - 6
O = 84The value of 0 is 84.
Given that,
Sin(0)= cos(6).
Based on the above information, the calculation is as follows:
cos θ =sin (90 - θ),
So in the case when θ = 6
So, O will be
O = 90 - θ
O = 90 - 6
O = 84
