Answer:

The volume of the cylinder is greater than the volume of the prism.

Step-by-step explanation:

The Volume of a cylinder is given as:

= πr²h

Therefore, the volume of a cylinder with a radius of 3 units and a height of 12 units will be:

= πr²h
=3.14 × 3² × 12

=339.12

The volume of a rectangular prism with dimensions 3 units x 3 units x 12 units will be:

= Length × Width × Height

Based on the calculation, the volume of the cylinder is greater than the volume of the prism.

Answer:

B: The volume of the cylinder is smaller than the volume of the prism.

Step-by-step explanation:

In order to find the volume of the cylinder, we would use to formula [tex]\pi r^{2} h[/tex]. Substitute the given measures of the cylinder to get [tex]\pi[/tex]·3²·12. The simplified and calculated form would be 108 units cubed.

Now, we find the volume of the rectangular prism, which is [tex]l[/tex]·[tex]w[/tex]·[tex]h[/tex], or 16*16*9. This means the volume is 2304 units cubed.

Therefore, since 2304 un³>108 un³, answer choice b would be correct.

The value of the quadratic equation x has a value of 0.8968 and a negative value of 2.23.

It is a method for dividing a polynomial into parts, each of which will be multiplied. At this time, the polynomial's value will be zero.

The equation for the expression is given below.

3x² + 4x = 6

3x² + 4x - 6 = 0

we know that the formula

[tex]\rm x = \dfrac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]

Then we have

[tex]x = \dfrac{-4 \pm \sqrt{4^2-4*4*(-6)}}{2*3}\\\\x = \dfrac{-4 \pm \sqrt{112}}{6}\\\\x = 0.8968, \ -2.23[/tex]

(any number less than 1, so it can't be one, but can be a negative number or zero - any number to the power of zero is one)

Step-by-step explanation:

Area = Pi x Radius^2

Diameter = Circumference / Pi

                 = 6Pi / Pi

                 = 6

Radius = Diameter / 2

             = 6 / 2

             = 3

Using proportions, it is found that she will need 12 pints of ice cream.

A proportion is a fraction of a total amount.

Each cup is equivalent to 0.5 pints. There are 24 students, and each student needs a cup, hence 24 cups are needed.

In pints, the equivalent amount is given by:

P = 24 x 0.5 = 12.

Answer:

I believe the answer would be B) x^2 - 16x + 64 = -21 + 64

Step-by-step explanation:

When you're completing the square you take the "middle" term (in this case it's -16) and you divide it by two, then square it. By doing that for this problem you get 64 (16/2 = 8 - 8^2 = 64; signs don't matter in this case because you multiply 2 negatives). You have to add that 64 to BOTH sides so that the equation evens out.

Ultimately, with it factored, the answer will be (x-8)^2

______----------________

Answer:

1134.11

Step-by-step explanation:

The problem with this equation is pi is an angle in radians. It has a never ending number of digits.

The area of a circle is basically a square r x r rotated through 180 degrees around the squares centre.

So the area can be written as 180 x 19 x 19 = 64980 degrees meters square.

This is a finite number. The area of a circle does not change. Pi r squared has an ever increasing result.

pi is a conversion factor between the finite areas of circles and the area in square units which can never have a result that is finite as squares cannot fill a circle, no matter how small.

To convert the round finite area to m squared you divide the area by 180/pi = 57.295779513 degrees per radian.

Area in degrees meters Squared 64980/ 57.295779513.

= 1134.1149479 radian meters squared.

Answer:

arc UH = 67°

Step-by-step explanation:

the measure of a chord- chord angle is half the sum of the measures of the arcs intercepted by the angle and its vertical angle , then

[tex]\frac{1}{2}[/tex] ( BE + UH ) = ∠ BKE , that is

[tex]\frac{1}{2}[/tex] (119 + UH ) = 93° ( multiply both sides by 2 to clear the fraction )

119° + UH = 186° ( subtract 119° from both sides )

UH = 67°

Answer:

Step-by-step explanation:

∠HKU = ∠BKE   {Vertically opposite angles}

∠HKU = 93°

Angles fromed by insecting chords equals half the sum of intercepting arcs.

      [tex]\sf \angle HKU =\dfrac{1}{2}(arc \ HU + arc \ BE) \\\\ 93^ \circ = \dfrac{1}{2}(arc \ HU + 119)[/tex]

   93 *2 = arc HU + 119

   186    = arc HU + 119

186 - 119 = arc HU

arc HU = 67°

Answer:

General form of an exponential equation: [tex]y=ab^x[/tex]

where:

Let x = years

Let y = investment value

Use (2, 692) and (4, 952) to find a and b of the exponential equation:

[tex]ab^2=692[/tex]

[tex]ab^4=952[/tex]

[tex]\implies \dfrac{ab^4}{ab^2}=\dfrac{952}{692}[/tex]

[tex]\implies b^2=\dfrac{238}{173}[/tex]

[tex]\implies b=\sqrt{\dfrac{238}{173}}=1.17\:\textsf{(nearest hundredth)}[/tex]

[tex]\implies ab^2=a\left(\dfrac{238}{173}\right)=692[/tex]

[tex]\implies a=\left(\dfrac{59858}{119}\right)=503.01\:\textsf{(nearest hundredth)}[/tex]

Therefore, the exponential equation is:

[tex]y=503.01(1.17)^x[/tex]

18 years after the initial investment is when [tex]x=18[/tex]:

[tex]\implies 503.01(1.17)^{18}=8490[/tex]

Therefore, the amount closest to the value of the investment 18 years after the initial investment is $8490

(If you use the exact values for a and b rather than the rounded values, the amount is $8879)

Answer:

x=9.167

Step-by-step explanation:

12x+240=350

350-240 because you are getting rid of 240 to get 12x by itself so you must do it on the other side.

12x=110, then you do 12x/12 and 110/12

x=9.167

Answer: Approimately $9.16

Step-by-step explanation:

In this problem, you have to solve for x variable.

1. Distribute the 12 to the x + 20 which is 12x + 240

2. Subtract 240 from both sides so 350 - 240 is 110.

3.  Now your equation is 110 = 12x

4. Divide 12 on both sides. But 12 doesn't go into 110 perfectly.

5. 110 divided by 12 is approximately 9.16.

The x represent how much the student has earn extra to get $350 in 12 months. The student has to earn 9.16 dollars every month on top of the 20 dollars.

Answer:

Option 2: (1, 0) and (0, -5)

Step-by-step explanation:

Let's solve this system of equations using the elimination method.

Start by labelling the two equations.

5x -y= 5 -----(1)

5x² -y= 5 -----(2)

(2) -(1):

5x² -y -(5x -y)= 5 -5

Expand:

5x² -y -5x +y= 0

5x² -5x= 0

Factorise:

5x(x -1)= 0

5x= 0 or x -1= 0

x= 0 or x= 1

Now that we have found the x values, we can substitute them into either equations to solve for y.

Substitute into (1):

5(0) -y= 5 or 5(1) -y= 5

0 -y= 5 or -y= 5 -5

y= -5 or -y= 0

y= 0

Thus, the solutions are (0, -5) and (1, 0).
