29. Having a large enclosed space has advantages, but it can be more expensive to heat and cool. Assume an air conditioner uses about 4 BTUs/cubic foot each hour (a BTU is a measure of energy). How many BTUs will the air conditioner need to produce each hour to cool the structures? Hint: Multiply the enclosed space by the number of BTUs needed per cubic foot. (3 points)
1: Cylinder
2: Pyramid
3: Dome
The BTU required by the air conditioner/hour to cool the following structures is given as:
Cylinder: 4*π r² h (Where h is height, and r is the radius);Pyramid: 4 (lwh/3) (Where l is the length, w - the width, and h, the height;Dome: 4 * (4/3 πr³)What is the explanation for the above?It is to be noted that the BTU required to cool per cubic foot of space is 4BTUs.
Since we are not given the dimensions of the structures, the required constant is thus, multiplied by the volume of the structures whose equations have been given above.
Note that:
Volume translates to enclosed space; and
BTU means British Thermal Unit.

Suppose a normal distribution has a mean of 26 and a standard deviation of 4. What is the probability that a data value is between 28 and 35? Round your answer to the nearest tenth of a percent.
A. 29.6%
B. 23.6%
C. 27.6%
D. 25.6%
Using the normal distribution, it is found that the probability that a data value is between 28 and 35 is given by:
A. 29.6%.
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.Researching the problem on the internet, the mean and the standard deviation are given by:
[tex]\mu = 26, \sigma = 4[/tex].
As a proportion, the probability that a data value is between 28 and 35 is the p-value of Z when X = 35 subtracted by the p-value of Z when X = 28, hence:
X = 35:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{35 - 26}{4}[/tex]
Z = 2.25
Z = 2.25 has a p-value of 0.988.
X = 28:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{28 - 26}{4}[/tex]
Z = 0.5
Z = 0.5 has a p-value of 0.692.
0.988 - 0.692 = 0.296 = 29.6%, which means that option A is correct.

An extension cord 6 yards long costs $8.46. What is the price per foot? There are 3 feet in 1 yard.
Submit
The extension cord is an illustration of unit rates, and the price per foot is $0.47 per foot
How to determine the price per foot?The given parameters are:
Length = 6 yards
Cost = $8.46
Convert the length from yard to feet.
So, we have:
Length = 6 feet * 3
This gives
Length= 18 feet
The price per foot is then calculated using:
Rate = Cost/Length
This gives
Rate = 8.46/18
Evaluate
Rate = 0.47
Hence, the price per foot is $0.47 per foot

Vince is cutting fabric strips for a project. He needs fabric strips that are 1212 inches wide. He cut his first fabric strip too wide. His percent error was 5%. How wide did Vince cut the fabric strip?
Answer:
13.125 inches wide
Step-by-step explanation:
5% more than 12.5 which is 12 1/2 as a decimal, equals 13.125 inches.
Multiply your needed fabric width (12.5 or 12 1/2) by (1 + %/percent you're increasing it by) to equal the width you cut instead:
[tex]12.5(1+5) = 12.5(1.05) = 13.125[/tex]

How many right angles are on this shape?
Explanation:
The term "right angle" is another way of saying "90 degree angle".
Such angles are marked as squares. Usually there are tiny square symbols inside the angle to be very clear that we have 90 degree angles. Some diagrams may not do this, and simply imply that anything that looks like a square 90 degree angle actually is one.
With this in mind, the angles that fit the description are angles J and M at the bottom of the figure. Therefore, there are 2 right angles in this shape.
Side note: This figure is a trapezoid because it has exactly one set of parallel sides KJ and LM.
What is the area of this figure? PLS ANSWER
Answer:
42 units ^2
Step-by-step explanation:
Break in to a top triangle a middle rectangle and a bottom triangle
area = 1/2 7 *2 + 4 * 7 1/2 * 2 * 7 = 42 units ^2
A surveyor measures the angle of elevation at 20° for a point 5 miles away what is the vertical change in elevation from the point where the surveyor is standing to the point 5 miles away???
help please
Step-by-step explanation:
there are just some big words trying to confuse you.
it just means that there is a right-angled triangle :
there is the point on the ground, where the surveyor is standing.
then there is the elevated point up there, where the surveyor was measuring the angle to.
and then there is the point on the ground directly under this elevated point. at this point in the ground we have the right angle (90°).
this height of the elevated point above this ground point is what we are looking for, and it is one leg of the right-angled triangle.
the ground distance from the surveyor to the ground point under the elevated point is 5 miles and the second leg.
the direct line of sight from the surveyor to the elevated point is inclined up by 20°, and is the Hypotenuse (baseline opposite of the 90° angle) of the triangle.
remembering that the sum of all angles in a triangle is always 180°, we also know the angle at the elevated point :
180 - 90 - 20 = 70°
now we are using the law of sine :
a/sin(A) = b/sin(B) = c/sin(C)
where the sides are always opposite to their associated angles.
so, we have in our triangle
height/sin(20) = 5/sin(70)
height = 5×sin(20)/sin(70) = 1.819851171... miles
so, the elevated point is 1.819851171... miles above the elevation of the surveyor.

Deremine the general solution of sin 2x - 4cos2x
Answer:
[tex]x=\frac{1}{2}\left(\tan^{-1}{4}+\pi k\right)[/tex], where k is any integer
Step-by-step explanation:
Let's start by getting all the trig functions on one side and all the constants on the other. We can do this by dividing both sides by [tex]\cos{2x}[/tex]:
[tex]\dfrac{\sin{2x}}{\cos{2x}}=4[/tex]
This ratio looks familiar! It just so happens that the tangent function is defined as the ratio of sine to cosine. In our case:
[tex]\dfrac{\sin{2x}}{\cos{2x}}=\tan{2x}[/tex]
Substituting this back into our equation, we have [tex]\tan{2x}=4[/tex]. We can unwrap the 2x by applying the inverse tangent function to both sides, giving us [tex]2x=\tan^{-1}{4[/tex]. Note, this specific solution only accounts for values of 2x between 0 and 2π radians. To make it general, we can add the term πk to the end of the right side, where k is any integer. We use π as a coefficient because the tangent function has a period of π radians, and it repeats its values every period.
Finally, we divide both sides of the equation by 2 to isolate x, giving us
[tex]2x=\tan^{-1}{4}+\pi k\\x=\frac{1}{2}\left(\tan^{-1}{4}+\pi k\right)[/tex]

The description for a certain brand of house paint claims a coverage of 410 ft2/gal. How many liters of paint are required to apply a single coat of paint to the (4) walls of a 7.7 m by 14.8 m room with a height of 2.4 m
Answer:
10.7 liters of paint requiredStep-by-step explanation:
Dimensions of the room
7.7 m by 14.8 m with the height of 2.4 mFind the surface area of the 4 walls
A = Ph = 2(l + w)h = 2(7.7 + 14.8)*2.4 = 108 m²Convert the area to ft²
108 m² = 108*10.7639 ft² = 1162.5012 ft²Find the amount of paint required
1162.5012/410 = 2.84 gal (rounded)Covert the volume to liters
2.84 gal = 2.84*3.76 l = 10.7 l (rounded)According to the fundamental theorem of algebra, which polynomial function has exactly 6 roots? f (x) = 5 x superscript 4 baseline 10 x squared 2 f (x) = 5 x superscript 5 baseline 3 x superscript 4 baseline 12 x cubed 7 x squared minus 2 x 15 f (x) = 6 x superscript 5 baseline x cubed minus 4 x squared x minus 5 f (x) = 7 x superscript 6 baseline 3 x cubed 12
The polynomial with 6 roots is the one of degree 6, so the correct option is:
[tex]f(x) = 7x^6 + 3x^2 + 12[/tex]
Which polynomial function has 6 roots?
You need to remember that if p(x) is a polynomial of degree N, then it has N roots (such that some of these N roots may be equal or not).
Then we just need to find the polynomial of degree 6. (Remember that the degree represents the maximum exponent of the polynomial).
In this case, the only one of degree 6 is:
[tex]f(x) = 7x^6 + 3x^2 + 12[/tex]

What is a regular polygon?A polygon is a geometric figure with a finite number of sides in two dimensions. On the sides or edges of a polygon, straight-line segments are joined end to end to form a closed shape. The vertices, also known as corners, are the points where two line segments meet and form an angle.
We have vertices for the polygon:
a=(-2,-3), b=(0,-3), c=(0,1), d=(3,1), e=(3,3), f=(-2,3)
After marking the coordinates on the coordinate plane and connecting the lines, we will get a polygon.
