Tyler finds an expression for V(x) that gives the volume of an open-top box in cubic inches in terms of the length x in inches of the square cutouts used to make it. This is the graph Tyler gets if he allows x to take on any value between -1 and 7.

What is the approximate maximum volume for his box?

Answers

Answer:

Step-by-step explanation:

Domain: 0<x<3.5

To get 3.5:  7/2=3.5

Negatives and decimals can't be used

Approximate maximum volume for this box?  55

The proper domain of Noah's graph should be 0 to 3.5 and the maximum of the graph is at y = 60.

It is required to find the approximate maximum volume for his box.

What is co-ordinate geometry?

Coordinate geometry is defined as the study of geometry using the coordinate points. Coordinate geometry is required to provide a link between algebra and geometry through the use of line and curve graphs.

Given:

From the attached graph (see attachment), we have the following observations:

1.The x values starts from -1 and ends at 60

2.The domain of the graph is from 0 to 4 (i.e. x-values 0 to 4 have corresponding y-values on the graph)

3.x-values 0 to 3.5 have corresponding non-negative y-values

4.Other values of x have corresponding negative y-values

5.The maximum of the graph is at y = 60

Because the volume of a box cannot be negative, the x-values to use must correspond to non-negative y-values.

Hence, the proper domain of Noah's graph should be 0 to 3.5 and the maximum of the graph is at y = 60.

A grain trader buys the following amounts from three suppliers: 3,200 pounds, 7,200 pounds and 600 pounds. What is the total weight of this purchase

Answers

1. You know that the grain trader buys from three suppliers: 3,200 pounds, 5,100 pounds and 700 pounds.
2. Then, to calculate the total weight of his purchase you only need to add the pounds shown in the problem, as you can see below: THE ANSWER IS B!

The total weight of the grain purchase is 5.5 tons when grain trader buys the following amounts from three suppliers: 3,200 pounds, 7,200 pounds and 600 pounds.

To find the total weight of the grain purchase in tons, we need to convert the weight from pounds to tons and then sum them up.

Given the weights from the three suppliers:

Supplier 1: 3,200 pounds

Supplier 2: 7,200 pounds

Supplier 3: 600 pounds

To convert pounds to tons, we divide the weight in pounds by the conversion factor of 2,000 (since there are 2,000 pounds in a ton).

Supplier 1's weight in tons: 3,200 pounds / 2,000 = 1.6 tons

Supplier 2's weight in tons: 7,200 pounds / 2,000 = 3.6 tons

Supplier 3's weight in tons: 600 pounds / 2,000 = 0.3 tons

Now, we can calculate the total weight by summing up the weights from each supplier:

Total weight in tons: 1.6 tons + 3.6 tons + 0.3 tons = 5.5 tons

Therefore, the total weight of the grain purchase is 5.5 tons.

Hope this helped :)

The pressure exerted by the block can be obtained as 60 N/m².

What are arithmetic operations?

The arithmetic operations are the fundamentals of all mathematical operations. The example of these operators are addition, subtraction, multiplication and division.

Since, the pressure is obtained as the ratio of Force to area.

It can be worked out using the following operation as,

Pressure = Force ÷ Area

⇒ 120 ÷ 2 = 60 N/m².

Hence, the pressure can be obtained as 60 N/m².

7. A computer software manufacturer wanted to know if its customers were satisfied with
the graphics in a new game program called Zinger they released six months ago. The
company randomly polled 1000 of the 50,000 people who had purchased the program.
Here is part of the results of the poll:
Zinger Program Graphics Percent
Satisfied with Graphics 42%
Not Satisfied with Graphics
No Opinion 13%
a. What percent of the 1000 game users surveyed were not satisfied with the graphics
of Zinger? (2 points)
b. Based on the survey findings, how many of the current 50,000 game users would the
company expect to not be satisfied with the graphics or to have no opinion? (3
points)
c. Based on the survey findings, the software manufacturer has decided to create a new
version of the game program with improved graphics. Why did they make this
decision? (2 points)



Please I don't have any more points

Answers

Answer:

A)

45% of customers were not satisfied with the graphics.

B)

22,500 people are expected to not be satisfied with the graphics.

6,500 people are expected to have no opinion.

C)

The majority of people are unsatisfied with the graphics.

Step-by-step explanation:

The company polled 1,000 out of the 50,000 people who had purchased the program.

42% was satisfied with the graphics.

And 13% had no opinion.

Part A)

When totaled, those satisfied, unsatisfied, and with no opinion should be 100%.

Since 42% are satisfied and 13% have no opinion, this leaves 100 - 42 - 13 or 45%.

So, 45% of customers were not satisfied with the graphics.

Part B)

Since 45% of the polled were unsatisfied with the graphics, 45% of the total 50,000 can also be expected to not be satisfied.

45% of 50,000 is 0.45(50000) = 22500.

So, 22,500 people are expected to not be satisfied with the graphics.

Likewise, 13% had no opinion.

So, 13% of 50,000 is 0.13(50000) = 6500.

6,500 out of the current 50,000 customers are expected to have no opinion with the graphics.

Part C)

Since the majority of people are unsatisfied with the graphics (45% > 42%), it is reasonable to create a new version with improved graphics.

Solve the equation for -2/3x= -12
A. -18
B. -8
C. 8
D. 18

Answers

D.18 is the answer for that

Answer:

D, 18.

Step-by-step explanation:

1. We need to separate any value from x, so we must remove (-2/3) from the left side of the equation and place it on the right by dividing by (-2/3).

-2/3(x) = -12

2. We recognize that the negatives cancel each other out, so it cannot be A or B. Also, remember that dividing by a fraction or decimal will always increase the value of your answer. Therefore, the answer must be 18.

x = -12 times -3/2

x = 36/2

x = 18

Step-by-step explanation:

Since were not given the diagram of the circle. Let's assume the radius of inner circle is x+4

radius r = x+4

Area of the circle = πr²

Area of the circle = π(x+4)²

Area of the circle = π(x+4)(x+4)

Area of the circle =π(x²+4x+4x+16)

Area of the circle = π(x²+8x+16)

Area of the inner circle in terms of pi is (x²+8x+16)π in²
