The perimeter of a face of a cube is 16 mm. What is its volume?

64 mm 3
4096 mm 3
512 mm 3
128 mm 3

Answer:

The volume (V) of a cone can be calculated using the formula: V = (1/3)πr^2h, where r is the radius and h is the height.

Substituting the given values, we get:

V = (1/3) x 3.14 x 9^2 x 16

Calculating this expression gives us:

V = 1810.08 cubic inches

Rounding to the nearest hundredth gives us:

V ≈ 1810.08 cubic inches (rounded to two decimal places)

Therefore, the volume of the cone is approximately 1810.08 cubic inches.

Answer:

1363.04

Step-by-step explanation:

V = (1/3) * 3.14 * 9^2 * 16

Simplifying:

V ≈ 1363.04 cubic inches

The function for the points are  y = -15x - 5

From the information given, we have that;

The points are;

(1/3,0) (-2 3/4,0) and (0,-5)

Using the point-slope form of a linear equation, we have;

y - y₁ = m(x - x₁)

Such that;

Using (1/3, 0) and (0, -5), we have that the slope is;

m = (0 - (-5))/0 -1/3)

expand the bracket

= 5 / (-1/3)

= -15

Now, take any of the given points and substitute the values

Using (1/3, 0), we get;

y - 0 = -15(x - 1/3).

y = -15x - 5.

The function for the points solved by  (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)

We have given the points:

(1/3,0) (-2 3/4,0) and (0,-5)

Using the formula of linear equation

\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)                                                          

Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)

that is 1/3 = \(a\), 0 = \(a_{1}\) and

0 = \(b\), -5 = \(b_{1}\)

\(x\) refers to the slope of line (take any variable)

Now for finding the value of \(x\),

\(x=a-a_{1}/b-b_{1}\)

inserting the values,

\(x=[0-[-5]]/[0-1/3]\\x= -15\)

Substitute the value of \(x\) in the equation

\(a-0=-15[b-1/3]\)

By simplifying the equation, we get

\(a=-15b-5\)

Explanation:

The formula y - y1 = m(x - x1) is usually described as the 'point-slope form' for the equation of a line. It is useful because if you know one point on a certain line and the slope of that certain line, then you can define the line with this type of formula and, thus, find all the other points on that certain line.

Answer:

Mean = 33.7

Median = 34.5

Mode = 34

Range = 33

After adding 26....

mean decreases by 0.7

median decreases by 0.5

mode is 34

range is 33

Step-by-step explanation:

mean = sum of all the data values/number of data values

= (18 + 19 + 20  + 34 + 34 + 35 + 37 + 42 + 47 + 51)/10
= 337/10
= 33.7

To find median arrange the values in increasing order, find the mid value

If the number of data points is even, find the average of the mid 2 data values

Arranging data values we get:
18, 19, 20, 34, 34, 35, 37, 42, 47, 51

Since there are 10 data values, take the average of the middle two:
(34 + 35)/2 = 34.5

The mode is the value that occurs most often. We see that there are two instances of 34 whereas the other values appear only once

Mode = 34

The range is highest - lowest = 51 - 18 = 33

After we add 26, we get the following data set arranged

18, 19, 20, 26, 34, 34, 35, 37, 42, 47, 51

we can calculate the stats using the same technique as above

We get the following values

mean = )(18 + 19 + 20 + 26 + 34 + 34 + 35 + 37 + 42 + 47 + 51)/11
= 33  

median = 34

mode = 34

range = 51-18 = 33

To find the decrease in mean and median subtract from the first set of values

  Geometric sequences are exponential functions

Step-by-step explanation:

Geometric sequences are exponential functions.

The general term of a geometric sequence is given by the exponential function ...

  a[n] = a[1]·r^(n-1)

where a[1] is the first term and r is the common ratio.

You will notice that the independent variable (n) is in the exponent of this function. Hence it is an exponential function.

Answer:

Let the number of kinds of amplifiers be "a".

Antonio has 4 choices for the stereo and 3 choices for the speakers. Therefore, the total number of different choices he can make is:

4 (choices of stereos) x 3 (choices of speakers) x a (choices of amplifiers) = 12a

We are given that he has 36 different choices, so:

12a = 36

Dividing both sides by 12, we get:

a = 3

Therefore, there must be 3 kinds of amplifiers.

Answer:

Hi!

Your answer here is 39 cm.

Answer:

25.685 square feet.

Step-by-step explanation:

Circumference = 2 * π * radius

From this, we can derive the formula for the radius:

radius = Circumference / (2 * π)

Let's substitute the value of the circumference and calculate the approximate radius:

radius = 18 / (2 * π)

radius ≈ 18 / (2 * 3.14159)

radius ≈ 2.865 feet

Now that we have the approximate radius, we can calculate the area:

Area ≈ π * radius²

Area ≈ 3.14159 * (2.865)²

Area ≈ 3.14159 * 8.193225

Area ≈ 25.685 square feet

Therefore, the approximate area inside the circular park is approximately 25.685 square feet.

Answer:

Step-by-step explanation:

Tall candle:

Height = 16 cm

Let x be number of hours

Height that is burnt in 'x' hours = 2.5 *x = 2.5x

Height of the candle after 'x' hours (H) = 16 - 2.5x

When x = 1  ;   H = 16 - 2.5*1 = 16 -2.5  = 13.5 cm

          x = 2 ;   H = 16 - 2.5*2 = 16 - 5   = 11 cm

          x = 3 ; H = 16 - 2.5 * 3 = 16 - 7.5 = 8.5 cm

          x = 4 ; H = 16 - 2.5*4  =  16 - 10   = 6 cm

          x = 5 ; H = 16 - 2.5*5  =  16 - 7.5 = 3.5 cm

          x = 6 ; H = 16 - 2.5*6  =  16 - 15   = 1 cm

Short candle:

Height =12 cm

Let x be number of hours

Height that is burnt in 'x' hours = 1.5 *x = 1.5x

Height of the candle after 'x' hours (h) = 12 - 1.5x

When x = 1  ;   h = 12 - 1.5*1 = 12 - 1.5 = 10.5 cm

          x = 2 ;   h = 12 - 1.5*2 = 12 - 3 = 9 cm

          x = 3 ;   h = 12 -1.5*3  = 12 - 4.5 = 7.5 cm

          x = 4 ;   h = 12 -1.5*4  = 12 - 6   = 6 cm

          x = 5 ;   h = 12 -1.5*5  = 12 - 7.5 = 4.5 cm

          x = 6 ;   h = 12 -1.5*6  = 12 - 9 = 3 cm    

          x = 7 ;   h = 12 -1.5*7  = 12 - 10.5 = 1.5 cm

C)  Intersection point of the two equation is an ordered pair that is solution to both equations.

Here, after 4 hours the height of the both the candle is 6 cm

(4 , 6) is the solution of these two equations.

Y-intercept is the point of intersection where x = 0

X-intercept is the point of intersection at x-axis where y = 0

Yes the short candle can burn more than 7 hours. Short candle can burn for 8 hours

Answer:

the inly way this could be a function is iif it is x times 0 plus 2

Answer:

  yes

Step-by-step explanation:

You want to know if the relation shown is a function.

A set of ordered pairs (x, y) represents a function if there are no repeated x-values. Here, there are 4 unique x-values for the 4 ordered pairs (none are repeated), so this relation is a function.

Additional comment

Yes, it's that simple.

Look down the x-list. If you see any repeats, it is not a function. The same is true for ordered pairs (x, y). If there are any repeated first numbers, it is not a function.
