Receipts represents income to the company. It is a source of cash inflow. Expenses represents cash outflow. Net cash flow is the difference between receipts and expenses. Cumulate balance is the sum of the net cash flow of the previous periods and the net cash flow of the present period.

A = Net cash flow + expenses

1975 + 125 = 2100

B = Receipts - expense

$2225 - $1925 = $300

C =  Receipts - expense

$2050 - $2000 = $50

D = Net cash flow = $270

E = cumulative balance in April + net cash flow in May

$570 + $375 = $945

The diameter of a cylindrical container is 22cm. If the volume of the container is 1331cm³, calculate its height.

Answers

Answer:

3.5cm

Step-by-step explanation:

Vol=πr²h

Transposing for h,=vol÷πr²

where r=22/2=11cm and taking π=3.142

h=1331/(3.142×(11)²)=3.5cm

Answer is 3.5 cm

Step by step

For cylinders we know
Volume = pi x radius ^2 x height

We know volume is 1331
We know pi = 3.14
We know radius is 11 (diameter is 22, so radius is 1/2 of that, so r=11)
We are looking for height “H”

Fill in the numbers into the formula

1331 = 3.14 x 11^2 x H

1331 = 3.14 x 121 x H

1331 = 380 H

Divide both sides by 380 to solve for H

1331/ 380 = 380/ 380 H

3.5 = Height

Do you think it would be better to use breaking apart in the distributive property or compensation to find the product of five times 328? explain why and show how to find the product.

Answers

Yes it would be better to use breaking apart in the distributive property or compensation to find the product of 5 x 328 .

what is distributive property?

This property states that multiplying the total of two or more addends by a number will produce the same outcome as multiplying each addend by the number separately and then adding or substracting the results together .like in subtraction  A(B-C)= AB-AC

In other words, an equation of the type A (B+C) can be solved as A (B+C) AB+AC in accordance with the distributive property.

This characteristic also holds for subtraction.

5 x 328

= 5(300+28)

= 5 x 300 + 5 x 28

= 1500 + 140

= 1640

Hence, it would be better to use breaking apart in the distributive property or compensation to find the product of 5 x 328 .

A​ town's population is 42,975 . About 125 people move out of the town each month. Each​ month, 175 people on average move into town. A nearby town has a population of 45,225. It has no one moving in and an average of 175 people moving away every month. In about how many months will the populations of the towns be​ equal? Write an equation to model the situation. Then solve the equation and answer the question.

Answers

The number of months when they will be equal is 45 months.

How to calculate the equation?

The equation for the first town will be:

= 42975 + 125x

The equation for the second town will be:

= 45225 + 175x

The number of months when the populations of the towns will be equal will be:

42975 - 125x = 45225 - 175x

- 125x + 175x = 45225 - 42975

50x = 2250

x = 2250 / 50

x = 45

Which of the following describes a situation in which the total distance a baseball player travels is zero meters from his starting point? (5 points)

Answers

Situation (B) best describes how a baseball player travels a total distance of zero meters from his starting point, that is, the player runs 3 meters forward and then 3 meters in the opposite direction.

What is the distance?Distance is a numerical or quantifiable measurement of the distance between two objects or points. The distance can refer to a physical length or an estimate based on other criteria in physics or everyday usage (e.g. "two counties over"). Because spatial thinking is a rich source of conceptual metaphors in human thought, the term is also frequently used figuratively to mean a measurement of the amount of difference between two common pieces (such as statistical distance between probability distributions or edit distance between text strings) or a degree of detachment (as exemplified by the distance between people in a social network). The concept of a metric space is used in mathematics to formalize most such notions of distance, both physical and metaphorical.

According to the options:

Options (A), (C), and (D) is wrong as there the basketball travels some sought distance from the starting point. It is only in option (B) in which the total distance of the baseball player comes to 0 as he runs 3 meters forward and then runs 3 meters in the opposite direction.

Therefore, situation (B) best describes that the total distance a baseball player travels is zero meters from his starting point that is, the player runs 3 meters forward and then runs 3 meters in the opposite direction.

This graph represents a quadratic function. What is the function’s equation written in factored form and in vertex form?

Answers

The equation of the parabola in vertex form is y + 8 = 2 · (x - 2)². The factored form of the equation of the parabola is y = 2 · x · (x - 4).

What is the equation of the parabola seen in a graph?

Herein we find a representation of a quadratic function on a Cartesian plane, whose formula in vertex form is presented below:

y - k = C · (x - h)²

Where:

(h, k) - Vertex of the parabola.C - Vertex constant

By direct inspection we find that the equation of the parabola has a vertex at (h, k) = (2, - 8) and the point (x, y) = (4, 0). Then, the vertex constant is:

C = (y - k) / (x - h)²

C = (0 + 8) / (4 - 2)²

C = 8 / 4

C = 2

Then, the equation of the parabola in vertex form is y + 8 = 2 · (x - 2)². The factored form of the equation is determined by algebra:

y + 8 = 2 · (x - 2)²

y = 2 · (x - 2)² - 8

y = 2 · (x² - 4 · x + 4) - 8

y = 2 · x² - 8 · x + 8 - 8

y = 2 · x² - 8 · x

y = 2 · x · (x - 4)

The factored form of the equation of the parabola is y = 2 · x · (x - 4).
