Given:
The dimensions of a box are 3ft, 3ft and 13 ft.
To find:
The length of the longest flagpole that could be shipped inside the box.
Solution:
We know that the length of longest flagpole that could be shipped inside the box is equal to the length of the diagonal.
[tex]Diagonal=\sqrt{l^2+b^2+h^2}[/tex]
Where, l is length, b is breadth and h is height.
[tex]Diagonal=\sqrt{(3)^2+(3)^2+(13)^2}[/tex]
[tex]Diagonal=\sqrt{9+9+169}[/tex]
[tex]Diagonal=\sqrt{187}[/tex]
[tex]Diagonal\approx 13.67[/tex]
Therefore, the longest flagpole that could be shipped is about 13.67 feet long.

Part C: What are the steps you would use to graph f(x)? Justify that you can use the answers obtained in Part A and Part B to draw the graph. (5 points)
Answer:
Part A & B
Step-by-step explanatPart A:
f(x) = 4x ^ 2 - 7x - 15
0 = 4x ^ 2 - 7x - 15
a = 4, b = -7, c = -15
a x c = -60
-12 x 5 = -60
-12 + 5 = -7
(4x + 5)(4x - 12)
4x ^ 2 - 12x I + 5x - 15
4x(x - 3) + 5(x - 3)
(x - 3)(4x + 5)
x = 3 x = -1.25 or -5/4
Part B:
Minimum point
(x1 + x2)/2
(3 -1.25)/2 = 0.875
f(x) = 4x ^ 2 - 7x - 15
f(0.875) = 4(0.875) ^ 2 - 7(0.875) - 15
f(0.875) = 3.06 - 6.125 - 15
f(0.875) = -18.065ion:

The number 70 is decreased to 41. What is the percentage by which the number was decreased, to the nearest tenth of a percent?
Answer:
Decreased percent = 41.4 % (Approx.)
Step-by-step explanation:
Given:
Old number = 70
New number = 41
Find:
Decreased percent
Computation:
Decreased number = 70 - 41
Decreased number = 29
Decreased percent = [29 / 70]100
Decreased percent = 41.42%
Decreased percent = 41.4 % (Approx.)

Mei runs 60.36 miles in 4 weeks. If she runs 3 days each week, what is the average distance she runs each day?
Answer:
15.09
Step-by-step explanation:
She ran only 12 times every 4 weeks, so we divide 60.36 by 4 which then becomes the result of running 3 days a week which means the answer is 15.09 because 15.09 multiplied by 4 is 60.36.
Answer:
The answer is 15.09.
A student wants to compare the mean times needed to access flight information for two major airlines. 20 randomly selected students accessed one airline's Web site, and the time required to locate the flight information had a mean of 2.5 minutes and a standard deviation of 0.8 minute. 20 different randomly selected students accessed the other airline's Website, and the time required to locate the flight information on that site had a mean of 2.1 minutes and a standard deviation of 1.1 minutes. Assuming that the conditions for inference are met, which of the following statements about the p-value is true?A. The p-value is less than 0.01; therefore, there is a significant difference in mean search times on the two WebsitesB. The p-value is greater than 0.01 but less than 0.05; therefore, there is a significant difference in mean search times on the two WebsitesC. The p-value is greater than 0.05 but less than 0.10; therefore, there is a significant difference in mean search times on the two WebsitesD. The p-value is greater than 0.10; therefore, there is no significant difference in mean search times on the two WebsitesE. Since this is a matched-pairs situation, additional information is needed to perform a test of significance.
Answer:
The statement which can be true about the p-value is;
A. The p-value is less than 0.01; therefore, there is a significant difference in mean search times on the two Websites
Step-by-step explanation:
Whereby the p-value is less than the significance level or pre-defined number we reject the null hypothesis that there is no difference in the mean time it takes to access the Websites of the two major airlines
Where the p-value is larger than the significant level, we fail to reject the null hypothesis and therefore, there is not enough evidence to indicate that the mean time to access the Websites of the two major airlines are different
The p-value is compared with a given level for the test, for it to be assed
The option that has the correct inference based on only one significant level or predefined is the p-value is less than 0.01; therefore, there is a significant difference in mean search times on the two Websites
The statement which can be true about the p-value is (A).
A. The p-value is less than 0.01; therefore, there is a significant difference in mean search times on the two Websites
What is the p-value?
The p-value in statistics is the likelihood of getting outcomes at least as severe as the observed results of a statistical hypothesis test, given the null hypothesis is valid.
The reason for option A is correct.
We reject the null hypothesis that there is no difference in the meantime it takes to visit the Websites of the two main airlines when the p-value is less than the significance level or pre-defined number.
We fail to reject the null hypothesis when the p-value is greater than the significant threshold
Hence there is insufficient evidence to suggest that the meantime to visit the websites of the two main airlines is different.
For the test to be assessed, the p-value is compared to a predefined level.
The p-value is less than 0.01 in the option that has the accurate inference based on only one significant level or predetermined; hence, there is a considerable difference in mean search times.

The coordinate point from the given graph is (3, -5). Therefore, option A is the correct answer.
What is coordinate plane?A coordinate plane is a two-dimensional surface formed by two number lines. It is formed when a horizontal line (the X-axis) and a vertical line (the Y-axis) intersect at a point called the origin. The numbers on a coordinate grid are used to locate points.
From the given coordinate plane, the coordinate point lies in fourth quadrant.
Where, x-coordinate is positive and y-coordinate is is negative.
The coordinate point correspond to x-axis is 3 and coordinate point correspond to y-axis is 5.
So, the coordinate point is (3, -5)
Therefore, option A is the correct answer.

If AC = 30 and AE = 3x + 3, then x = ________.
If DC = 6x + 1, BC = 2y + 2, AB = 25, and AD = 14, then x = _______ and y = _______.
Answer and Step-by-step explanation:
Part 1:
AE is equal to EC
3x + 3 + 3x + 3 = 30
6x = 24
x = 4
DC is equal to AB
6x + 1 = 25
6x = 24
x = 4
BC is equal to AD
2y + 2 = 14
2y = 12
y = 6

A right angled triangular prism has length 3m, breadth 2m and height 2.5m. If the mass of the prism is 3.4kg, find its density
Answer:
The density of the prism is 0.453 kilograms per cubic meter.
Step-by-step explanation:
Let suppose that mass in the prism is uniformly distributed. Then, the definition of density ([tex]\rho[/tex]), in kilograms per cubic meter, is defined by the equation below:
[tex]\rho = \frac{m}{V}[/tex] (1)
Where:
[tex]m[/tex] - Mass, in kilograms.
[tex]V[/tex] - Volume of the right angle triangle prism, in cubic meters.
Besides, the volume of the right angle triangle prism is:
[tex]V = \frac{1}{2}\cdot b\cdot h\cdot l[/tex] (2)
Where:
[tex]b[/tex] - Breadth of the base, in meters.
[tex]h[/tex] - Height of the base, in meters.
[tex]l[/tex] - Length of the base, in meters.
If we know that [tex]b = 2\,m[/tex], [tex]h = 2.5\,m[/tex], [tex]l = 3\,m[/tex] and [tex]m = 3.4\,kg[/tex], then the density of the prism is:
[tex]V = 7.5\,m^{3}[/tex]
[tex]\rho = 0.453\,\frac{kg}{m^{3}}[/tex]
The density of the prism is 0.453 kilograms per cubic meter.

A roll of tape has a circumference of 14.8 centimeters. The circumference decreases 2.4 centimeters after you use some of the tape. What is the diameter of the roll after you use the tape? ROUND to the nearest HUNDREDTH. I need answers quick
Answer:
7.900 cm
Step-by-step explanation:
The computation of the diameter after using the tape is given below:
Since the circumference is 14.8 cm
And it would be decrease by 2.4 cm
So, the new circumference is
= 14.8 - 2.4
= 12.4 cm
Now the radius is
= 12.4 ÷ π
= 3.95
And, the diameter is
= 3.95 × 2
= 7.900 cm
