Find the measure of angle b.

The formula for the height of a cylinder is h = V / (π.r²) and the height of a cylinder with a volume of 36 cm³ and a radius of 3 cm is  4/π cm

Given a cylinder with a radius r and height h, then its volume is given by the formula:

      V = π.r².h

Where:

V = volume

r = radius

h = height

To find the formula for the height, divide both sides by π.r²

V : π.r² = π.r².h : π.r²

or,

           h = V / (π.r²)

The given parameters are:

V = 36 cm³

r = 3 cm

Substitute those parameters into the formula:

h = 36 / (π.3²)

h = 36 / (9π)

h = 4/π cm

The equation in slope-intercept form is y = -3/2x + 9. Slope of the equation is - 3/2 and y - intercept is 9.

Calculate the slope (m).

Keep in mind that the slope is determined by dividing the change in y by the change in x. (rise over run).

Find the y-value of the y-intercept by solving (b).

In the formula y=mx+b, swap out m and b with their respective values.

The given equation is -

3x + 2y = 18

divide the equation by 2

3/2x + y = 9

Rearranging the equation -

y = -3/2x + 9

Comparing it with y = mx + c

so slope m = -3/2

and y - intercept = 9

The geometric mean of a and b [tex]=\sqrt{a*b}[/tex] then the geometric mean of 8 and 18 is 12.

In Mathematics, the Geometric Mean (GM) is the average value or mean which signifies the central tendency of the set of numbers by finding the product of their values. Basically, we multiply the numbers altogether and take the nth root of the multiplied numbers, where n is the total number of data values.

The geometric mean is used in finance to calculate average growth rates and is referred to as the compounded annual growth rate.

To calculate the geometric mean of two numbers, you would multiply the numbers together and take the square root of the result.

Answer:

A

Step-by-step explanation:

The line travels through the plane and its intersection point is labeled C

The polynomial function V to represent the volume of a round bale is  V(x) = π(x + 5)²(x + 8).

A polynomial function is a function that involves only non-negative integer powers or only positive integer exponents of a variable in an equation like the quadratic equation, cubic equation, etc.

Let the dimensions of round bale is x+5 feet radius and 3 feet wide.

As we know that round bale is a shape of cylinder in which we will consider wide instead of height.

Volume of Round Bale (V) = πr²w

    V = πr²w = π(x + 5)²[(x + 5) + 3]

V(x) = π(x + 5)²(x + 8)

Hence, we got the polynomial function that represent the volume of round bale is  V(x) = π(x + 5)²(x + 8).

Answer:

Volume = 665 cm³

Step-by-step explanation:

We can calculate the volume of a cylinder using the following formula:

[tex]\boxed{\mathrm{Volume = \pi r^2 h}}[/tex],

where:

• r = radius of cylinder

• h = height of the cylinder

In the question, we are told that the diameter of the cylinder is 8.4 cm. Since the diameter is twice of radius:

[tex]\mathrm{radius = 8.4 \div 2}[/tex]

          [tex]= \bf 4.2 \: cm}[/tex]

We are also told that the height of the cylinder is 12.0 cm. Therefore, using this information, as well as the formula above, we can find the volume of the cylinder:

[tex]{\mathrm{Volume = \pi \times (4.2 \mathrm{\: cm})^2 \times 12.0 \mathrm{\: cm}}}[/tex]

            [tex]= \pi \times 17.64 \mathrm{\: cm^} \times 12.0 \mathrm{\: cm}[/tex]

            [tex]\approx \bf 665 \: cm^3[/tex]

Therefore the volume of the cube is 665 cm³.

The distance traveled in each section will be 150 meters and 350 meters.

The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance to time.

We know that the speed formula

Speed = Distance/Time

From a simultaneous equation for: A cyclist completes a journey of 500 m in 22 seconds, part of the way at 10m/s and the remainder at 50m/s.

Let x distance be covered with velocity 10 m/s in time t₁ and the remaining distance (500 - x) covered with velocity 50 m/s in time t₂. Then the equation will be

t₁ + t₂ = 22          ....1

Then the time t₁ will be

10 = x / t₁

t₁ = x / 10

Then the time t₂ will be

t₂ = (500 - x) / 50

Put the time in equation 1, then we have

x / 10 + (500 - x) / 50 = 22

5x + 500 - x = 1100

4x = 600

x = 150 meters

And the remaining distance will be

500 - x = 500 - 150

500 - x = 350 meters

The distance traveled in each section will be 150 meters and 350 meters.

There were 29 nickels and 10 dimes in the bank.

We know that:

1 dime = 5 cents

1 nickel = 10 cents.

Also, $ 3.40 = 340 cents

Let the  number of nickels be n and the number of dimes be d.

Now, we are given that:

5 dimes and 2 nickels were taken away.

So, total coins = 46 - 2 - 5 = 46 - 7

Total coins = 39

We get the equation:

n + d = 39

d = 39 - n

Now, we also know that:

5 d + 10 n = 340

d + 2 n = 68

Put the value of d, we get that:

39 - n + 2 n = 68

n = 68 - 39

n = 29

d = 39 - n

d = 39 - 29
