Step-by-step explanation:

Volume of a cone 1/3(nr^2h)

n = 3.14

r = radius  

h = height

1/3 x 3.14 x 25^2 x 129 = 84,327.50 cubic meters

Answer:

i thiiiink its b

Step-by-step explanation:

Answer:

When we have a function f(x), the average rate of change in the interval (a, b) is:

[tex]r = \frac{f(b) - f(a)}{b - a}[/tex]

In this case, we have the function:

f(x) = (x + 3)^2 - 2

(but we do not have the interval, and I couldn't find the complete question online)

So if for example, we have the interval (2, 4)

The average rate of change will be:

[tex]r = \frac{(4 + 3)^2 - 2 - (2 + 3)^2 + 2}{4 - 2} = \frac{24}{2} = 12[/tex]

If instead, we want the rate of change in a differential dx around the value x, we need to differentiate the function (this is way more complex, so I will define some rules first).

Such that the rate of change, in this case, will be:

f'(x) = df/dx

For a function like:

g(x) = x^n + c

g'(x) = n*x^(n - 1)

And for:

h(x) = k( g(x))

h'(x) = k'(g(x))*g'(x)

So here we can write our function as:

f(x) = k(g(x)) = (x + 3)^2 - 2

where:

g(x) = x + 3

k(x) = x^2 - 2

Then:

f'(x) = 2*(x + 3)*1 = 2*x + 6

That is the rate of change as a function of x (but is not an "average" rate of change)

Answer:

65.45

Step-by-step explanation:

Zscore = (x - mean) / standard deviation

x = score

Percentage below C :

D = 18% ; F = 12%

Sum = 30%

Obtain the Zscore for the proportion below D

P(Z < 0.30) = -0.524

Hence, Zscore = -0.524

Put Zscore = -0.524 in the equation :

-0.524 = (x - 72) / 12.5

-0.524 * 12.5 = x - 72

-6.55 = x - 72

-6.55 + 72 = x

x = 65.45

To receive a grade of C or better, score must be atleast 65.45

Answer:

[tex](b)\ 2x^2- 7[/tex]

Step-by-step explanation:

Required

Which is a trinomial and has a constant term

The highest degree of a trinomial is 2;

So, (b) and (d) are trinomial.

However, (b) has a constant term of -7 alongside the trinomial [tex]2x^2[/tex] while (d) has a constant term and also have a term with coefficient of x

Hence, (b) is correct

Answer:

Hey Friend.

Here is your answer↓

It is given that:-

Dividend=55390.

Divisor=299.

Remainder=75.

By Division algorithm:-

DIVIDEND=(DIVISOR× QUOTIENT)+REMAINDER

→ Quotient=(Dividend-Remainder)÷Divisor.

=(55390-75)÷299

=55315÷299

=185.

Hence, Quotient=185.

Hope it helps

Answer:

b = 20 cm.

Step-by-step explanation:

Define and explain:

This is a right triangle, so the Pythagorean Theorem applies.

The Pythagorean Theorem states that the sum of the squared legs will equal the squared length of the hypotenuse.

The legs of a triangle are the sides that form the right angle.

The hypotenuse is the longest side; the hypotenuse is always diagonal from the small square indicating a right angle.

Solve:

[tex]a^2+b^2=c^2[/tex]

[tex]a,b-legs[/tex]

[tex]c-hypotenuse[/tex]

[tex]15^2+b^2=25^2[/tex]

[tex]225+b^2=625[/tex]

[tex]625-225=400[/tex]

[tex]b^2=400[/tex]

[tex]b=20[/tex]

Conclude:

Therefore, the length of the unknown side is 20 centimeters.

Answer:

72

Step-by-step explanation:

When you multiply 9 and 5 you get 45. When you subtract 6 from 24 you get 18.

45 + 18 = 72

If helpful please mark me brainliest!

The correct expression for the sum of the product of 9 and 5 and the difference of 24 and 6 will be (9 × 5) + (24 -6) which will be equal to 63.

Mathematical actions are called expressions if they have at least two terms that are related by an operator and include either numbers, variables, or both. Adding, subtraction, multiplying, and division are all reflection coefficient operations.

A mathematical operation such as reduction, addition, multiplication, or division is used to integrate terms into an expression.

As per the given statement in the question,

Product of 9 and 5 i.e., 9 × 5 and,

Difference of 24 and 6 i.e., 24 - 6

Thus sum will be,

(9 × 5) + (24 - 6)

The result of the expression is 63.

Answer:

At an interest rate of 4.5% compounded annually, it will take 16.17 years to reach $17,323.-

Step-by-step explanation:

Giving the following information:

Present Value (PV)= $8,500

Future value (FV)= $17,323

Interest rate (i)= 4.5%

To calculate the time required for the investment to reach the objective, we need to use the following formula:

n= ln(FV/PV) / ln(1+i)  

n= ln(17,323/8,500) / ln(1.045)

n= 16.17 years

At an interest rate of 4.5% compounded annually, it will take 16.17 years to reach $17,323.-

Answer:

radius is 17

Step-by-step explanation:

Use "completing the square" to rewrite the given equation in standard form for a circle centered at (h, k) with radius r:

x^2+y^2-14x+10=250 becomes:

x^2 - 14x + y^2 = 240 after grouping x terms and  y terms separately.

Completing the square, once for x and once for y, results in:

x^2 - 14x + 49 - 49 + y^2 = 240.

Rewriting x^2 - 14x + 49 as the square of the binomial x - 7 results in:

(x - 7)^2 + y^2 = 289 = 17^2

From this we recognize that the center is at (7, 0) and the radius is 17.

This question is incomplete, the complete question is;

Your friend Mona claims that the average student debt immediately after graduation in the United States is $24,500. You want to see if your university has lower student debt at graduation. To test this, you randomly collect data from 40 students who recently graduated. The average of your sample is $22,413, with an associated standard deviation of $7,312. Using this data to perform the hypothesis test; H₀ : μ = 24,500 vs Hₐ : μ < 24,500.

What is the p-value of this test and conclusion at ∝ = 0.05  

Answer:

a) p-value = 0.0394

b) Since p value ( 0.0394 ) is less than ∝ ( 0.05 ), We reject the null hypothesis.

Hence, There is insufficient evidence at ∝ = 0.05 to claim that  the average student debt immediately after graduation in the United States is $24,500.

Step-by-step explanation:

Given the data in the question;

sample size n = 40

sample mean x' = 22413

level of significance ∝ = 0.05

standard deviation s = 7312

Hypothesis;

Null Hypothesis             H₀ : μ = 24,500

Alternative Hypothesis Hₐ : μ < 24,500

Test Statistics;

t = (x' - μ) / ( s/√n)

we substitute

t = (22413 - 24500) / ( 7312 / √40)

t = -2087 / 1156.1287

t = -1.805

Degree of Freedom DF = n - 1 = 40 - 1 = 39

With t = -1.8052 and df = 39

p( t < -1.805 ) = 0.0394

p-value = 0.0394

Since p value ( 0.0394 ) is less than ∝ ( 0.05 ), We reject the null hypothesis.

Hence, There is insufficient evidence at ∝ = 0.05 to claim that  the average student debt immediately after graduation in the United States is $24,500.
