The front and side elevation diagram along with the diagram given in question is attached with the answer.
What is elevation?
A location's elevation can be defined as its height above or below a fixed reference point, most frequently a reference geoid, a mathematical representation of the Earth's sea level as an equipotential gravitational surface (see Geodetic datum Vertical datum). In most cases, elevation is used to describe locations on the surface of the Earth, whereas altitude or geopotential height is used to describe locations above the surface, such as those of flying airplanes or orbiting satellites, and depth is used to describe locations below the surface.
Drawing the required Elevation Using the Construction Method
The scale is 2 squares to 1 meter.
16 squares total make up the plane on which the front elevation is to be drawn.
Front elevation: There are 4 squares across the front elevation's width.
4 + 1 squares make up the portion of the front closest to the observer.
The slant surface of the has a square count of 3 by 4 squares.
Side elevation: By following the same format as before, the side elevation is provided as follows;
The lower side of the side elevation's breadth is 2 meters wide, or 4 squares.
The side elevation's height is 2 meters, or 4 squares.

Neil has been running a tutoring business since 2005. He charges a monthly fee for weekly tutoring sessions and a phone help line. Each year, he has increased his fee by the same amount. The table shows what Neil charged each customer for two given years of his business:
Year Annual Tutoring Fee
2005 $1200
2008 $1350
A. What is the rate of change and initial value for Neil's business? How do you know?
B. Write an equation in slope-intercept form to represent the fees that Neil charges each year. (10 points)
The equation in slope intercept form that represent the situation is y = 50x - 99050.
How represent linear equation in slope intercept form?Linear equation can be represented in slope intercept form as follows:
y = mx + b
where
m = slopeb = y-interceptNeil charges a monthly fee for weekly tutoring sessions and a phone help line. Each year, he has increased his fee by the same amount.
Using the table that shows the amount he charged for tutoring each year. we can find the rate of change.
The rate of change is the slope.
Therefore, (2005, 1200)(2008, 1350)
m = slope = 1350 - 1200 / 3
slope = 150 / 3
slope = 50
Therefore, let's represent the equation in slope intercept form. We will have to find the y-intercept of the equation.
Hence, using (2005, 1200)
y = 50x + b
1200 = 50(2005) + b
b = 1200 - 100250
b = - 99050
Hence, the equation is y = 50x - 99050.

If you select two different women at random, what’s the probability that:
A. At least one experienced IPV?
B. At least one did not experience IPV?
The probability of selecting at least one experienced IPV is 0.598 and at least one did not experience IPV is 0.866.
In the given question we have to find the probability of selecting at least one experienced IPV and at least one did not experience IPV
From the given table
Probability of experiencing IPV
P(Experienced IPV) = 366 / 1000 = 0.366
Probability of not experiencing IPV
Q(Not-experienced IPV) = 634 / 1000 = 0.634
Now when n samples are chosen from the population, the binomial probabilty distribution follows (P + Q)^n.
Here, n = 2,
So, (p +q)^2 = p^2 + 2pq + q^2
p^2 = Both experienced IPV
2pq = One has experienced IPV and other hasn’t
q^2 = None have experienced IPV.
A. Finding the probability of at least one experienced IPV.
P(At least one has experienced IPV) = P^2 + 2PQ
= (0.366)^2 + 2(0.366)(0.634)
=0.1339+0.4641
= 0.598
B. Finding the probability of at least one did not experienced IPV.
Q(At least one did not experienced IPV) = Q^2 + 2PQ
= (0.634)^2 + 2(0.366)(0.634)

a random sample of high school seniors were asked whether they were applying for college. the resulting confidence interval for the proportion of students applying for college is (0.65,0.69). what is the margin of error?
Using the confidence interval, the margin of error is 0.02.
In the given equation we have to find the margin of error.
The resulting confidence interval for the proportion of students applying for college is (0.65,0.69).
Let p = population proportion of students applying for college
P = Sample proportion of students applying for college
ME = margin of error
So the confidence interval
CI = (P-ME, P+ME)
From the given question;
(P-ME, P+ME) = (0.65,0.69)
So lower bound= P-ME = 0.65............................(1)
Upper Bound = P+ME = 0.69............................(2)
Simplifying the Equation 1 and 2
Add equation 1 and 2 we get
2P = 1.34
Divide by 2 on both side we get
P = 0.67
Putting the value of P in the equation 2
P+ME = 0.69
0.67+ME=0.69
Subtract 0.67 on both side we get
ME = 0.02
Hence, the margin of error is 0.02.

The c has only one number is c = 81/4 that satisfy the conclusion of rolle's theorem.
The three hypotheses of Rolle's theorem are:
(a) f(x) is continuous on [a,b]
(b) f(x) is differentiable on (a,b)
(c) f(a) = f(b)
i) If you graph f(x), you can see that it is continuous that is no breaks on the interval [0,81]
ii) f(x) is differentiable on (0,81)
f '(x) = 1/(2√x) - 1/9 which exists on the open interval (0,81)
iii) f(0) = f(81) = √81 - 81/9 = 9-9 = 0
Rolle's Conclusion:
f'(c) = 0
f'(c) = 1/(2√c) -1/9 = 0
(9 - 2√c)/(18√c) = 0
√c = 9/2

Answer:
Fiona would need 12 pages to hold all 212 stickers.
Step-by-step explanation:
Since each page holds 18 stickers, and Fiona has 212 stickers, we need to divide.
212 / 18 = 11.7777778 pages
Because that we cannot have .77777778 of a page, we round to the nearest page, getting us 12 pages.

The option that explains Sarita's mistake is Sarita’s solution is correct. She made an error in her verification.
What was Sarita's mistake?The given equation is: 5(x - 3) + 7(x + 4) = 73
In order to determine the value of x, take the following steps:
1. Apply the Distributive property:
5x - 15 + 7x + 28 = 73
2. Add similar terms together:
12x + 13 = 73
3. Combine similar terms:
12x = 73 - 13
4. Add similar terms
12x = 60
5. Divide both sides of the equation by 12
x = 60 / 12
x = 5
In order to verify the answer, substitute for x in the given equation :
5(5 - 3) + 7(5 + 4) = 73
5(2) + 7(9) = 73

What is a root in mathematics?
In mathematics, a number's "root" is a number that, when multiplied by itself, equals the original number; alternatively, a number's "root" can also be an equation's solution, which is typically presented as a number or an algebraic formula.
For instance, since 7*7=49, the square root of 49 is 7. In this instance, 7 is referred to as the square root of 49 since it must be multiplied twice to produce the number. 3 because 3*3*3=27 is the cube root of 27. Since 27 is obtained by multiplying 3 by three, we refer to this as a cube root, so 3 is the cube root of 27.

Answer:
7.07 cm/min
Step-by-step explanation:
You want the rate of change of water level in a conical tank 16 m high with radius 4 m when the level is 12 m and the water is draining at 2 m³/min.
Surface areaThe level of water in the tank is 12/16 = 3/4 of the height of the tank, so the radius of its surface is (3/4)(4 m) = 3 m. The surface area is ...
A = πr²
A = π(3 m)² = 9π m² ≈ 28.3 m²
Level changeThe rate of change of level is the rate of change of volume divided by the surface area:
V'/A = (-2 m³/min)/(9π m²) = -2/(9π) m/min ≈ -0.07074 m/min
The water level is falling at about 7.07 cm/min.

Answer:
no, because 3 + 5 < 9
Step-by-step explanation:
given three sides of a triangle
For the sides to form a triangle the sum of any 2 must be greater than the third.
given sides 3, 5 and 9 , then

3 + 5 = 8 < 9
the 3 sides do not form a triangle since 3 + 5 < 9
