An airplane is flying at an altitude of 6 miles (approximately 32,000 feet) toward a point directly above where you are standing. If you are standing x miles away from a spot that is perpendicular to the plane, what is the equation that relates the angle as a function of x? Then, using that equation, solve for when x is 2 miles.
Answer:
angle = arc tangent(6/x)
for x=2 -> angle = 71.565°
Step-by-step explanation:
To find the relation of the distance x and the angle of elevation that you are seeing the airplane, we should use the tangent relation of the angle. The opposite side of the angle is the altitude of the airplane, and the adjacent side of the angle is the distance x.
So we have that:
tangent(angle) = 6/x
angle = arc tangent(6/x)
If we have the value of x = 2, the angle will be:
angle = arc tangent(6/2) = arc tangent(3)
angle = 71.565°

A jewelry box has a length of 3 1/2 units, a width of 1 1/2 units, and a height of 2 units. What is the volume of the box in cubic units?
Answer:
10 1/2 or 10.5
Step-by-step explanation:
V=l*w*h
Volume = length * width * height
length = 3 1/2 = 3.5
width = 1 1/5 = 1.5
height = 2
input the values V = 3.5 * 1.5 *2
multiply the first two numbers 3.5 * 1.5 = 5.25
multiply the first result by the third number 5.25 * 2 = 10.5
Volume = 3.5 * 1.5 *2= 5.25 * 2 = 10.5 = 10 1/2
3 1/2 * 1 1/5 * 2 = length * width * height = Volume = 10 1/2
Volume = 10 1/2

A cylinder has a radius of 24.6 inches and a volume of 29,468 in3. Find its height.
A. 14.5 in
B. 15 in
C.15.5 in
D. 16.5 in
Answer:
15.49 inches
Step-by-step explanation:
Volume of a cylinder is given by
[tex]V=\pi r^{2}h[/tex]
Making h the subject of the formula then
[tex]h=\frac {V}{\pi r^{2}}[/tex]
Where h is the height, V is volume and r is radius. Substituting 24.6 inches for r and 29468 cubic inches for V then
[tex]h=\frac {29468}{\pi 24.6^{2}}=15.493723673378\ in\approx 15.49\ in[/tex]
Therefore, the height is approximately 15.49 inches
The correct height of the cylinder that produces a volume of 29,468 in3 is 15 inches (Choice B).
To find the height of a cylinder with a volume of 29,468 cubic inches (in3) and a radius of 24.6 inches, we use the formula for the volume of a cylinder, V = πr²h, where V is the volume, r is the radius, and h is the height.
Plugging in the known values, we get:
29,468 in3 = π(24.6 in)2h
Solving for h, the height of the cylinder, we perform the following steps:
Calculate the base area: Base Area = π(24.6 in)2
Divide the volume by the base area to find the height: h = Volume / Base Area
Calculate the height: h = 29,468 in3 / (π(24.6 in)2)
After performing the calculation, we conclude that the correct height of the cylinder that produces a volume of 29,468 in3 is 15 inches (Choice B).
I am the fewest number of coins needed to
make 37 cents using only pennies, nickels,
and dimes. Who am I?
What is the answer
Answer:
6 coins
Step-by-step explanation:
3 dimes
1 nickel
2 pennies
Answer: 6 coins
Step-by-step explanation:
Pennies = 1c
Nickels = 5c
Dimes = 10c
10 * 3 dimes = 30c
30c + 5c (a nickle) = 35c
35c + 2 pennies = 34
Therefore, the lowest amount of coins is 6 (3 dimes, 1 nickle, and 2 pennies)

Answer:

did test on edge, got 100%
The height of the prism is x-3+ (7x-9)/([tex]x^{3}[/tex]-3[tex]x^{2}[/tex]+5x-3).
The formula for the volume of a rectangular prism is V = Ah, where A is the area of the base and h is the height. Since we are given the volume and the area of the base, we can solve for the height. We have V = ([tex]x^{2}[/tex]-2) * h and V = ([tex]x^{3}[/tex]-3[tex]x^{2}[/tex]+5x-3), so we can set these two equations equal to each other and solve for h.
([tex]x^{2}[/tex]-2) * h = ([tex]x^{3}[/tex]-3[tex]x^{2}[/tex]+5x-3)
Expanding both sides, we get:
[tex]x^{2}[/tex]h - 2h = [tex]x^{3}[/tex]h - 3[tex]x^{2}[/tex]h + 5xh - 3h
Combining like terms, we get:
([tex]x^{3}[/tex] - 3[tex]x^{2}[/tex] + 5x - 3 - [tex]x^{2}[/tex] + 2 - 5x + 3) * h = 0
Simplifying, we get:
([tex]x^{3}[/tex] - 4[tex]x^{2}[/tex] + 2) * h = 0
Since [tex]x^{3}[/tex] - 4[tex]x^{2}[/tex] + 2 cannot equal 0 (since it's a cubic polynomial), we can divide both sides by ([tex]x^{3}[/tex] - 4[tex]x^{2}[/tex] + 2) to solve for h:
h = 0 / ([tex]x^{3}[/tex] - 4[tex]x^{2}[/tex] + 2)
So the height of the prism is x-3+ (7x-9)/([tex]x^{3}[/tex]-3[tex]x^{2}[/tex]+5x-3).

What is 54 in scientific notation
Answer:
5.2 times 10^1
Step-by-step explanation:
the first number should be less than ten.
Answer: [tex]5.4[/tex] [tex]x[/tex] [tex]10^{1}[/tex]
Step-by-step explanation: To write a number in scientific notation, first write a decimal point in the number so that there is only one digit to the left of the decimal point.
So here, we have 5.4 and notice that there
is only one digit to the left of the decimal point.
Next, we count the number of places the decimal point would
need to move to get back to the original number, 54.
Since we would need to move the decimal point 1 place to the right,
we have an exponent of positive 1.
Now, scientific notation is always expressed as a number between 1 and 10 including 1 but not 10 and it is multiplied by 10 to a certain power that must be an integer.
So we have [tex]5.4[/tex] [tex]x[/tex] [tex]10^{1}[/tex]
Notice that the exponent is positive.
This is because we would need to move the decimal point to the right in order to get back to the original number.
So 54 can be written in
scientific notation as [tex]5.4[/tex] [tex]x[/tex] [tex]10^{1}[/tex].

Find the area of a circle with a diameter of 6.
Either enter an exact answer in terms of pi or use 3.14 for pi and enter your answer as a decimal.
To find the area of a circle with a diameter of 6, divide the diameter by 2 to get the radius, then use the formula Area = πr² with the calculated radius, resulting in an area of 28.26.
Using either the exact value of π (pi) or its approximation 3.14, we substitute the radius into the formula to calculate the area.
Using π, the area is:
A = π(3)² = 9π
Using the approximation of 3.14 for π, the area is:
A = 3.14(3)² = 3.14(9) = 28.26
So, the area of the circle is either 9π square units or approximately 28.26 square units if you use 3.14 for π.
What is the height of the cylinder in the diagram? Round your answer to the nearest whole number.
Answer: 8
Step-by-step explanation:
As per the given volume and radius of the cylinder, the height of the cylinder in the diagram is approximately 8 cm.
In order to determine the height of the cylinder in the given diagram, we first need to understand the formula for calculating the volume of a cylinder. The formula for the volume of a cylinder is
=> V = π * r² * h,
where V represents the volume, π is a constant (approximately equal to 3.14159), r is the radius, and h is the height of the cylinder.
In the provided information, we are given that the radius of the cylinder is 6 cm (radius = 6 cm) and the volume of the cylinder is 904.78 cm³ (V = 904.78 cm³).
Now, we can rearrange the volume formula to solve for the height (h) of the cylinder. Divide both sides of the formula by (π * r²):
h = V / (π * r²)
Substitute the known values:
h = 904.78 cm³ / (3.14159 * 6²)
h = 904.78 cm³ / (3.14159 * 36)
h = 904.78 cm³ / 113.09724
h ≈ 7.99998 cm
Rounding the answer to the nearest whole number, the height of the cylinder is approximately 8 cm.

This cuboid is made from centimetres cubes
write down the volume of the cuboid
using the image below
the cuboid is then split in half
Answer:
72 for q1 and q2 is 18
Step-by-step explanation:
Final answer:
To find the volume of a cuboid, multiply its length, width, and height. If made of 1 cm cubes, the volume is the number of these cubes. Halving the cuboid evenly would halve its volume.
Explanation:
To calculate the volume of a cuboid, you multiply the length, width, and height of the cuboid. The question doesn't provide specific dimensions, but assuming that you have them, the formula you would use is Volume (V) = length × width × height. If the cuboid consists of centimeter cubes, each with a side length of 1 cm, the volume in cubic centimeters will be equal to the number of these small cubes.
For example, let's say the dimensions of the cuboid are 5 cm × 3 cm × 4 cm. The volume would then be calculated as V = 5 cm × 3 cm × 4 cm = 60 cm³.
If the cuboid is split in half, the resulting two pieces would each have a volume that is half of the original total volume, assuming the split is made evenly.
Find the area of a
regular hexagon with
an apothem of
15 cm.
DO
The area of the regular hexagon is 585 square centimeters.
Explanation:A regular hexagon is a polygon with six equal sides and six equal angles. To find the area of a regular hexagon, you can use the formula:
[tex]\[ \text{Area} = \frac{3 \sqrt{3}}{2} \times \text{side length}^2 \][/tex]
However, in this case, the apothem (the distance from the center to the midpoint of a side) is given instead of the side length. The relationship between the apothem (\(a\)) and the side length (\(s\)) of a regular hexagon is given by:
[tex]\[ a = \frac{s}{2} \times \sqrt{3} \][/tex]
Rearranging this formula to solve for \(s\), we get:
[tex]\[ s = \frac{2 \times a}{\sqrt{3}} \][/tex]
Substituting this expression for \(s\) into the area formula, we get:
[tex]\[ \text{Area} = \frac{3 \sqrt{3}}{2} \times \left(\frac{2 \times a}{\sqrt{3}}\right)^2 \][/tex]
Simplifying further:
[tex]\[ \text{Area} = \frac{3 \sqrt{3}}{2} \times \frac{4 \times a^2}{3} \][/tex]
Canceling out common factors:
[tex]\[ \text{Area} = 2 \sqrt{3} \times a^2 \][/tex]
Now, substituting the given apothem ((a = 15) cm), we find:
[tex]\[ \text{Area} = 2 \times \sqrt{3} \times (15 \, \text{cm})^2 = 585 \, \text{cm}^2 \][/tex]
Therefore, the area of the regular hexagon is 585 square centimeters.
