Answer:

300π ft^3

Step-by-step explanation:

let's use the volume of a cylinder formula:

π*r^2*h

π=3.14

r=5

h=12

since we need to solve in terms of pi, do not plug the value of pi into the formula

π*5^2*12= 300π

300π

Answer:

203 minutes

Step-by-step explanation:

This can be expressed as an arithmetic sequence, that is

20, 23, 26, 29,...

With first term a = 20 and common difference d = 3

The sum to n terms of an arithmetic sequence is

[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex] [ 2a + (n - 1)d ], hence

[tex]S_{7}[/tex] = [tex]\frac{7}{2}[/tex] [ (2 × 20) + (6 × 3) ]

                        = 3.5 ( 40 + 18) = 3.5 × 58 = 203

Answer:

y = - 7

Step-by-step explanation:

The y- intercept is the point on the y- axis that the line passes through.

The line passes through the y- axis at (0, - 7), hence

the y- intercept is - 7

Slope-intercept form: y = mx + b   [m is the slope, b is the y-intercept or the y value when x = 0 ---> (0 , y)]

Since you know m = -3, you can plug that into the equation

y = mx + b

y = -3x + b       To find b, plug in the point they gave you into x and y, but since x = 0, your y-intercept is -7

Answer:

3 left

Step-by-step explanation:

If she starts out with 73 and drops 5 she is left with 68, an you cannot evenly divide 68 and 13 so you divide it as much as you can evenly which is five containers leaving 3 extra cupcakes.

For this case we have that initially there are 73 cupcakes, if Leda dropped 5 then we are left with:

[tex]73-5 = 68[/tex]

Now, you must equally divide the 68 cupcakes into 13 containers:

putting 5 cupcakes in each of the 13 containers we have;

[tex]13 * 5 = 65[/tex]

[tex]68-65=3[/tex]

So, we have 3 cupcakes left.

Answer:

3 cupcakes

Answer:

D

Step-by-step explanation:

If y = log x is the basic function, let's see the transformation rule(s):

Then,

1. y = log (x-a) is the original shifted a units to the right.

2. y = log x + b is the original shifted b units up

Hence, from the equation, we can say that this graph is:

** 2 units shifted right (with respect to original), and

** 10 units shifted up (with respect to original)

only, left or right shift affects vertical asymptotes.

Since, the graph of y = log x has x = 0 as the vertical asymptote and the transformed graph is shifted 2 units right (to x = 2), x = 2 is the new vertical asymptote.

Answer choice D is right.

The area of the rectangle is decreased by 75%, when the dimensions of a rectangle are decreased by 50%.

The area of the rectangle is the multiplication of length and width.

Area = l × b

It is given that:  length and breadth is by 50%

New Length = l × (1-50/100)

                   = l × (1-1/2)

                  = l/2

New Width = b × (1-50/100)

                  = b × (1-1/2)

                 = b/2

New area = new length × new width

               = (l/2) x (b/2)

              = lb/4

Change percent =[tex]\frac{Final Area\;-\; Initial Area}{Initial Area} * 100[/tex]

                        = [tex]\frac{(lb/4)\;-\; lb}{lb} * 100[/tex]

                        = (- 3lb)/4× 100

                        = (-3)/4 × 100

                        =  -75%

Hence, the area decreased by 75 %.

Final answer:

Decreasing the dimensions of a rectangle by 50% results in a new area that is 25% of the original, equating to a decrease of 75% in the area.

Explanation:

When the dimensions of a rectangle are decreased by 50%, each dimension (length and width) becomes 50% of the original. To determine the effect on the area, you can use the formula for the area of a rectangle, which is Area = length tmes width.

Let's consider the original length to be L and the original width to be W. The original area is L times W. When both dimensions are decreased by 50%, the new length is 0.5L and the new width is 0.5W. Therefore, the new area is (0.5L) times (0.5W), which is 0.25 times (L times W). This means the new area is 25% of the original area, representing a 75% decrease.

9/n  =  10/m

Answer: Hi, in the equation 9*m = 10*n the proportion is 9 to 10, which means that 9 times the number m is equal to 10 times the number n.

So n is proportional to m in the way that n= (9/10)*m

and m is proportional to n in the way that m= (10/9)*n

This means that the proportion can be written as 9 to 10, or 9:10.

Answer: 4

Step-by-step explanation:

The degree is the highest exponent , in which in this problem it is 4. The 3x counts as an exponent of 1 because the variable x is 1, and the 2 counts as an exponent of zero. Which means the degree is 4.

Step-by-step explanation:

- 1/2x > 6

Divide both sides by -1/2:

x < -12   (Note the inequality sign flips when we divide by a negative value).

Answer: {x |x ∈ R, x < -12}

Step-by-step explanation:

Given the following inequality:

[tex]-\frac{1}{2}x>6[/tex]

You can find the solution set by solving for the variable "x".

Then, to solve for the variable "x" you need to multiply both sides of the inequality:

[tex](-\frac{1}{2}x)(2)>(6)(2)[/tex]

[tex]-x>12[/tex]

And finally, you must multiply both sides of the inequality by (-1). Notice that the direction of the symbol of the inequality will change:

[tex](-x)(-1)>(12)(-1)[/tex]

[tex]x<-12[/tex]

Therefore, the solution set is: {x |x ∈ R, x < -12}

Answer:

a) Domain: -∞ < x < ∞

b) Cost required to manufacture 3500 items is $15,900.

c) Number of items she can manufacture is 5208 if cost is kept at $20,000

Step-by-step explanation:

a) What is the reasonable domain of the function?

The function is C(x) = 7,500 + 2.4x

The domain of the function is the set of values for which the function is defined and valid.

In the given function there is no constraint or undefined points so domain is:

-∞ < x < ∞

b) What is the cost of 3,500 items?

We are given x = 3500 and we need to find the cost.

Putting values in the function given:

C(x) = 7,500 + 2.4x

C(x) = 7,500 + 2.4 (3500)

C(x) = 7500 + 8400

C(x) = 15,900

Cost required to manufacture 3500 items is $15,900.

c) If costs must be kept below $20,000 this month, what is the greatest number of items she can manufacture?

We are given cost, and we need to find x

C(x) = 7,500 + 2.4x

20,000 = 7500 +2.4x

20,000 - 7500 = 2.4x

12500 = 2.4 x

=> x = 12500/2.4

x= 5208.3 ≅ 5208

So, Number of items she can manufacture is 5208 if cost is kept at $20,000

The slope of this line is -1.

The slope formula is useful:

m = (y2 -y1)/(x2 -x1)

where:

m is the slope of the line

y1 and y2 are the y-coordinates of two points on the line

x1 and x2 are the x-coordinates of the two points on the line

 m = (2 -4)/(0 -(-2)) = -2/2 = -1

The slope of this line is -1.

The points on the line drop 1 unit for each 1 unit to the right.

 m = rise/run = -1/1 = -1

Answer:

Step-by-step explanation:

Using the midpoint formula

midpoint of 2 points (x₁, y₁ ) and (x₂, y₂ ) is

[ [tex]\frac{1}{2}[/tex](x₁ + x₂), [tex]\frac{1}{2}[/tex](y₁ + y₂ ) ]

let (x₁, y₁ ) = (- 1, 5) and (x₂, y₂ ) = (5, 5), then midpoint is

[ [tex]\frac{1}{2}[/tex](- 1 + 5), [tex]\frac{1}{2}[/tex](5 + 5) ]

= (2, 5) → D

The midpoint of the segment is (2,5).

To find the midpoint of a line segment with endpoints [tex]\((-1, 5)\) and \((5, 5)\)[/tex], we can use the midpoint formula:

[tex]\[ \text{Midpoint} = \left( \frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2} \right) \][/tex]

Given the endpoints:

[tex]\( x_1 = -1 \), \( y_1 = 5 \)[/tex] (coordinates of the first point)

[tex]\( x_2 = 5 \), \( y_2 = 5 \)[/tex] (coordinates of the second point)

Now, let's plug these values into the midpoint formula:

[tex]\[ \text{Midpoint} = \left( \frac{-1 + 5}{2}, \frac{5 + 5}{2} \right) \][/tex]

[tex]\[ = \left( \frac{4}{2}, \frac{10}{2} \right) \][/tex]

[tex]\[ = \left( 2, 5 \right) \][/tex]

Therefore, the midpoint of the segment is (2, 5)

Among the given options, the correct one is option D: (2, 5).

The value 1.8 represent the club's total number of members today or the present number of members

Step-by-step explanation:

Given an exponential function;

b is the base or the growth factor

a is the initial value, that is the value of y when x = 0

We have been given the exponential function;

[tex]y=1.8(1.02)^{12t}[/tex]

The value 1.8 simply represents the initial value of y. Plug in t = 0 in the equation;

[tex]y=1.8(1.02)^{12(0)}=1.8[/tex]

Therefore, the value 1.8 represent the club's total number of members today or the present number of members.
