In the square pyramid shown below, the slant height is 12 centimeters and the height of the pyramid is 7 centimeters.
To the nearest whole number, find the diagonal length of the base of the pyramid. In your final answer, include your calculations with reasoning for each step.
The diagonal of the square pyramid will be equal to 33.10 centimetres.
What is diagonal?The lines which connect the two opposite corners of any quadrilateral are called diagonal. here we have a square pyramid whose slant height and the vertex height are given and we have to find the diagonal length of the base.
Let the side of the square base of the pyramid is "a". Now the side will be calculated by the following relation.
[tex](\dfrac{a}{2})^2[/tex] = s² - H
[tex](\dfrac{a}{2})^2[/tex] = 12² - 7 = 137
a² = 137 x 4 = 548
a = √548 = 23.40 cm
Now the diagonal will be calculated by using the Pythagorean theorem
D² = 23.04² + 23.40²
D² = 548 + 548
D = √1096
D = 33.10 centimeter
Therefore the diagonal of the square pyramid will be equal to 33.10 centimetres.

Mila is designing a necklace with 12 platinum spherical beads that each have a radius of 7 millimeters. she has 350 grams of platinum to use. if pure platinum has a mass of 21.5 grams per cubic centimeter, does she have enough to make the 12 spherical beads? explain how you found your answer.
Volume is a three-dimensional scalar quantity. Mila only has 350 grams of platinum, therefore, she does not have enough platinum to make a necklace.
What is volume?A volume is a scalar number that expresses the amount of three-dimensional space enclosed by a closed surface.
The volume of 12 bead = 12 × (4/3) × π × R³
= 12 × (4/3) × π × (0.7)³
= 17.241 cm³
Given the density of platinum as 21.5 grams per cubic centimeter, therefore,
Mass = density × Volume = 370.682
Since Mila only has 350 grams of platinum, therefore, she does not have enough platinum to make a necklace.

Coordinates are numerical lengths or angles that uniquely identify locations on two-dimension. The missing coordinates are coordinates 3 and 4.
What is the best way to understand the Cartesian coordinate plane?A Cartesian coordinate plane is a two-dimensional plane with infinite dimensions. On an endless 2d plane, any two-dimensional figure may be drawn. A location is assigned to each point on a Cartesian plane.
It is the perpendicular distance between that point and the horizontal and vertical axes, which are commonly referred to as the x-axis and y-axis.
Location is then written as (a,b), where 'a' is the point's shortest distance from the y-axis, 'b' is the point's shortest distance from the x-axis, and 'c' is the point's shortest distance from the x-axis.
Coordinates are numerical lengths or angles that uniquely identify locations on two-dimensional (2D) surfaces or in three-dimensional (3D) space ( 3D ).
Mathematics, scientists, and engineers frequently employ a variety of coordinate systems.
Hence the missing coordinates are coordinates 3 and 4.

What is the point slope form of an equation of the line through the points (-2, 6) and (3, -2)
Could someone explain why the value of x is (-2).
Answer:
x = -2
Step-by-step explanation:
2x^3 +16 = 0
We are solving for x
Subtract 16 from each side
2x^3 +16- 16 = 0-16
2x^3 = -16
Divide each side by 2
(2x^3 ) /2 = -16/2
x^3 = -8
Take the cube root of each side
[tex]\sqrt[3]{x^3} = \sqrt[3]{-8}[/tex]
x = -2
Answer:
[tex]x=-2[/tex]
Step-by-step explanation:
Given equation:
[tex]2x^3+16=0[/tex]
To solve for the unknown variable x, apply arithmetic operations to isolate the variable.
Subtract 16 from both sides:
[tex]\implies 2x^3+16-16=0-16[/tex]
[tex]\implies 2x^3=-16[/tex]
Divide both sides by 2:
[tex]\implies \dfrac{2x^3}{2}=\dfrac{-16}{2}[/tex]
[tex]\implies x^3=-8[/tex]
Take the cube root of both sides:
[tex]\implies \sqrt[3]{x^3}=\sqrt[3]{-8}[/tex]
[tex]\implies x=-2[/tex]
When taking the cube root of a negative number, the result will be negative. To understand why, examine what happens when we cube a negative number.
When a number is cubed, it is multiplied by itself, then by itself again.
When multiplying a negative number by another negative number, the result is always positive.
When multiplying a positive number by a negative number, the result is always negative.
Therefore:
[tex]\begin{aligned}\implies (-2)^3 &= -2 \cdot -2 \cdot -2\\ & = 4 \cdot -2\\& = -8\end{aligned}[/tex]
So if -8 is cube rooted, the result is -2.
Choose all of the following angles that cannot
be an interior angle in a regular polygon.
24° 72°
72°
135°
135° 164° 179⁰
In a regular polygon, all interior angles have equal measures because the polygon has congruent sides and angles. The sum of all interior angles in a polygon can be found using the formula:
(n-2) * 180°,
where n represents the number of sides of the polygon.
Based on this, we can determine which angles cannot be interior angles in a regular polygon.
24°: This angle can be an interior angle in a regular polygon because it is smaller than the interior angles of any polygon with more than 6 sides.
72°: This angle can be an interior angle in a regular pentagon (5 sides) or any polygon with more sides, as it satisfies the requirement for interior angles.
135°: This angle cannot be an interior angle in a regular polygon because it is larger than the interior angles of any polygon with less than 8 sides.
164°: This angle cannot be an interior angle in a regular polygon because it is larger than the interior angles of any polygon with less than 9 sides.
179°: This angle cannot be an interior angle in any regular polygon because it is larger than the maximum measure of interior angles in any polygon.

Hey I need help on this question. Could I have a simple explaination as I find it difficult to understand things
Answer:
9
Step-by-step explanation:
The surface, in this case, describes the number of squares that are painted. On the left hand side, we have a cube, so we know we're going to have 6 faces. And each face on the cube has 9 little squares, they can be counted on the diagram. So, the total number of squares that are painted on the left cube = [tex]9 * 6 = 54[/tex]
The star means multiplication.
We are told in the question that it takes 9 litres of paint to cover the surface of the left hand cube, meaning it takes 9 litres of paint to cover 54 squares.
This can be written in the ratio = [tex]9:54[/tex]
If we divide both sides of the ratio by 9, we can figure out the amount of squares that 1 litre of paint covers, [tex]1:6[/tex].
The ratio tells us that 1 litre of paint covers 6 squares.
Let's look at the shape on the right. It is still a cube, however, some segments have been removed. Some faces still remain the same as in the shape on the left, such as the bottom face, the back face and the face to the left. Those faces may not be so apparent on the diagram, however, they exist. So we have to count them.
The number of small squares on these faces = [tex]9 * 3=27[/tex]
If you look on the inside of the cube, which can be seen on the diagram, we can see three faces, each having four squares. So, the total number of squares here = [tex]3*4=12[/tex]
Also, we have some squares on the top, and if you count these, there are 5.
This also applies for the front and the right hand side if you count, so we add 10 squares to the total as there are another two lots of five.
So, the total number of squares on the right cube = [tex]27 + 12 + 5 + 5 + 5 = 54[/tex]
Let's bring back the ratio of litres of paint to the number of squares covered: [tex]1:6[/tex]
In the ratio, there are 6 squares per litre. We know that 6 × 9 = 54 (our total). So, we multiply left hand side of the ratio by 9 as well, bringing the total amount of paint required to 9 litres.
I hope this helps.

A box is to be constructed with a rectangular base and a height of 5 cm. If the rectangular base must have a perimeter of 28 cm, which quadratic equation best models the volume of the box?.
Answer:
Volume = 7WH - (1/2)W^2H
Step-by-step explanation:
The base consists of the length (L) and the width (W). It is rectangular, so the perimeter would be the sum of all four sides:
Perimeter = L + W + L +W,
or Perimeter = 2L + 2W
We are told that 2L + 2W = 28cm [The perimeter is 28 cm]
------
The volume of the box is given by:
Volume = L*W*H [Length x Width x Height]
=====
Let's rearrange the first equation and use it in the second:
2L + 2W = 28cm
2L = 28cm - 2W
L = (28cm - 2W)/2
L = (14 - W)
Now use this definition of L (14 - W) in the second equation:
Volume = L*W*H
Volume = (14 - W)/2)*W*H
Volume = (7-(1/2)W)*W*H
Volume = 7WH - (1/2)W^2H
This can also be written as: Volume = WH(7 - (1/2)W)

The air force reports that the distribution of heights of male pilots is approximately normal, with a mean of 72.6 inches and a standard deviation of 2.7 inches.
Part A: A male pilot whose height is 74.2 inches is at what percentile? Mathematically explain your reasoning and justify your work. (5 points)
Part B: Air force fighter jets can accommodate heights of soldiers between 70 inches and 78 inches without compromising safety. Anyone with a height outside that interval cannot fly the fighter jets. Describe what this interval looks like if displayed visually. What percent of male pilots are unable to fly according to this standard? Show your work and mathematically justify your reasoning. (5 points)
Using the normal distribution, it is found that:
a) The pilot is at the 72th percentile.
b) 19.13% of pilots are unable to fly.
Normal Probability DistributionThe z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.The mean and the standard deviation are given, respectively, by:
[tex]\mu = 72.6, \sigma = 2.7[/tex].
Item a:
The percentile is the p-value of Z when X = 74.2, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{74.2 - 72.6}{2.7}[/tex]
Z = 0.59
Z = 0.59 has a p-value of 0.7224.
72th percentile.
Item b:
The proportion that is able to fly is the p-value of Z when X = 78 subtracted by the p-value of Z when X = 70, hence:
X = 78:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{78 - 72.6}{2.7}[/tex]
Z = 2
Z = 2 has a p-value of 0.9772.
X = 70:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{70 - 72.6}{2.7}[/tex]
Z = -0.96
Z = -0.96 has a p-value of 0.1685.
0.9772 - 0.1685 = 0.8087 = 80.87%.
Hence the percentage that is unable to fly is:

Which graph represents the inverse of function??
Answer: The first graph
Step-by-step explanation: A graph’s inverse will have all of their roots inverted as well. If you put the graph f(x)= 3x+3 into a graphing calculator, you’ll be able to see all the roots. From there, just invert (switch) the roots. Since on the original graph the most prominent roots are {(0,3), (-1,0),(-2,-3)}, you just need to invert those roots and find them ALL on one of the graphs, then you have your answer. So, the inverted roots will be {(3,0),(0,-1),(-3,-2)}.
