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

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 telephone pole is 54 feet tall. A guy wire runs 79 feet, from point A at the top of the telephone pole, to the ground at point B. The base of the telephone pole is at point C. Triangle ABC is a right triangle.

How far is it from the base of the telephone pole to point B where the guy wire is secured to the ground? Round to the nearest tenth of a foot.

ft

Answers

Answer:

57.7 ft

Step-by-step explanation:

54 squared + b squared = 79 squared

2916 + b squared = 6241

-2916                        -2916

b squared = 3325

b = 57.7

The distance that the base of the telephone pole to point B where the guy wire is secured to the ground is 57.7 feet

What is Pythagoras Theorem?

Pythagoras theorem states that for a right angled triangle, the square of the hypotenuse is the sum of the squares of base and altitude.

Given that triangle ABC is a right triangle.

Point A is the top of the telephone pole.

Point B is the point on the ground.

Point C is the base of the telephone pole.

Given,

AB = 79 feet

AC is the height of the telephone pole = 54 feet

Angle C is a right angle.

Using Pythagoras theorem,

(AB)² = (AC)² + (BC)²

79² = 54² + (BC)²

(BC)² = 79² - 54²

(BC)² = 3325

BC = √3325 = 57.66 ≈ 57.7 feet

Hence the length of the base of the pole form the ground where the wire is secured is approximately 57.7 feet.

PLSS HELP the length of a rectangle is 3 meters greater than 2 times the width the perimeter of a rectangle is 30 m what is the length of the rectangle​

Answers

Answer:

Width: 4 meters. Length: 11 meters

Step-by-step explanation:

If you do it correctly, the length should be 3 more greater than 4*2. 4*2= 8 +3= 11. Your perimeter= 30 meters. 11+11 accounting for both long sides of the rectangle= 22. Accounting for both sides of the width, so 4*2=8 + our 22= 30 meters. Yw.

The length of the rectangle​ width 4 meters and length 11 meters.

If you do it correctly,

The length should be 3 more greater than

What is the perimeter of a rectangle?

P=2(l+w)

L= Length

W = Width

4*2. 4*2= 8 +3= 11.

Your perimeter= 30 meters.

11+11 accounting for both long sides of the rectangle= 22.

Accounting for both sides of the width,

So 4*2=8 + our 22= 30 meters.

Therefore we get the length of a rectangle is  11 meters.

Does (0, 0) make the equation y = 9x − 5 true?

Answers

Answer:

no

Step-by-step explanation:

y = 9x − 5

The point (0,0) means x=0 and y=0

Substitute this into the equation and see it is true

0 = 9*0 -5

0 = 0-5

0 = -5

This is not true so the point is not a solution.

What is the equation of the line that passes through the point ( -1, 1) and is perpendicular to 2x + 4y = 16?
A. y = −2x − 1
B. y − 3 = 2x
C. y = 6x + 7
D. Cannot be determined

Answers

Answer:

B

Step-by-step explanation:

We want the equation of the line that passes through the point (-1, 1) and is perpendicular to:

[tex]2x +4y=16[/tex]

Remember that the slopes of perpendicular lines are negative reciprocals of each other.

So, let's find the slope of the original line first. We can do so by converting it to slope-intercept form. Thus:

[tex]4y=-2x+16[/tex]

Therefore:

[tex]\displaystyle y=-\frac{1}{2}x+4[/tex]

The slope is -1/2.

The negative reciprocal of -1/2 is 2.

Thus, the slope of our new line is 2.

The slope is 2 and it passes through the point (-1, 1).

We can use the point-slope form:

[tex]y-y_1=m(x-x_1)[/tex]

Substitute:

[tex]y-(1)=2(x-(-1))[/tex]

Distribute:

[tex]y-1=2x+2[/tex]

Subtracting 2 from both sides yields:

[tex]y-3=2x[/tex]

Therefore, our answer is B.

Find the height of a cone with a diameter of 12 m and whose volume is 133 m.

A. 2 m
B. 9 m
C. 3 m
D. 1 m

Answers

Answer:

D

Step-by-step explanation:

Here, we want to get the height of the cone

radius = diameter/2

r = 12/2 = 6 m

To get this, we use the formula for the volume

V = 1/3 * pi * r^2 * h

133 = 1/3 * 3.142 * 22/7 *6^2 * h

h = 1.12 m
