What prism or other 3-dimensional shape would you use to model the tree trunk below? (Rectangular prism, triangular prism, square prism, or cylinder). If the height of the tree trunk is 13 ft and the radius is 1.5 ft, what is the volume in cubic feet?
Answer:
cylinder91.9 ft³Step-by-step explanation:
a)An object with a uniform circular cross section is generally modeled by a cylinder.
__
b)The formula for the volume of a cylinder is ...
V = πr²h
For the given radius and height, the volume is ...
V = π(1.5 ft)²(13 ft) ≈ 91.9 ft³
The volume of the tree trunk is about 91.9 ft³.

Find the slope of the graph
Answer: The slope of the graph is -2
Step-by-step explanation:
Take any two points from the graph, and do rise/run
For example, we take (1,3) and (2,1)
Apply rise/run... rise: 2, run: -1
2/-1 = -2
m = -2
For the next question, the slope is 4
And the last question, the slope is 1 1/2

This is with tangents I have already figured out one portion of the problems please help
Answer:
-5
Step-by-step explanation:
negative times negative is positive so squared can be negative or positive
Answer:
x = -5, x = 5
Step-by-step explanation:
Tangents to a circle drawn to a point outside the circle are equal in length. Therefore, AB = AC.
Given:
AB = x² + 8AC = 33AB = AC
⇒ x² + 8 = 33
Subtract 8 from both sides: x² = 25
Square root both sides: x = ±5
Therefore, x = -5, x = 5

Model the following verbal description below with an equation, Table, and graph. The table must include at least five data points. The table must include at least five data points. The basketball team wants to order shirts for the game days. The t-shirt company charges a $5 flat rate for using their services and $2 for every letter on the shirt.
Modeling of a situation is getting its properties held in another system, usually mathematical. The equation for given situation is [tex]C = 2T + 5[/tex]
How to form mathematical expression from the given description?You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.
For the given case the number of t-shirts brought is not known, so let we take it as T
Since each t-shirt costs $2, thus, T t-shirts will cost: T × $2
Since, cost of using the service of the t-shirt company is $5 flat rate, thus,
Total cost for purchasing T t-shirts = T × $2 + $5
Let total cost be denoted by C, then:
[tex]C = 2T + 5[/tex]
(we usually don't write multiplication sign usually, and write the quantities close to each other, denoting that they're in multiplication.)
(we usually don't write symbols like $ etc in equations. It is known from context like what type of currency is in discussion(if multiple currency, then we can do some modification to variable symbols).
Thus,
The equation for given situation is [tex]C = 2T + 5[/tex]
Table for it, using values of T from 1 to 5, we get:
[tex]\begin{array}{cc}T&C\text{(In dollars)}\\1&7\\2&9\\3&11\\4&13\\5&15\end{array}[/tex]
Plotting them in graph, we get the following attached graph.

In the table to the right, the P(0) is blank so we can assume P(O) = 0 What does a probability equal to zero mean?
Answer:
It means there is no chance this will happen or in other words a 0% chance
Step-by-step explanation:
100 points for user sweet Jennifer Whenever we observe a distant planet, star or galaxy, we are seeing it as it was hours, centuries or even millennia ago. This is because light travels at a finite speed (the speed of light) and given the large distances in the Universe, we do not see objects as they are now, but as they were when the light was emitted.
A construction company takes 1 3/8 hours to remove 2 1/2 metric tons of dirt from a construction site. What is the unit rate in metric tons per hour? Write your answer as a fraction or a mixed number in simplest form.
PLEASE HELP!! NO LINKS PLZ
Answer:
1 9/11 T/h
Step-by-step explanation:
You want the unit rate in metric tons per hour of removal of 2 1/2 metric tons in 1 3/8 hours.
Unit rateThe unit rate in tons per hour is found by dividing tons by hours:
(2 1/2 T)/(1 3/8 h) = (5/2 T)/(11/8 h) = (20/8 T)/(11/8 h) = 20/11 T/h
= 1 9/11 T/h
The unit rate is 20/11 metric tons per hour, or 1 9/11 metric tons per hour.

What is the measure of angle Y in this figure
Y=____ degrees
Answer:
163
Step-by-step explanation:
What's great about these problems is that when there is a line that is divided by another line, causing 2 angles, the 2 angles must equal 180 degrees. That means the 163-degree angle + either the x or the z angle would equal 180 degrees. The second best part about this is that if it is separated how yours is, with 2 lines, opposite angles are equal. That means that angle x and angle z are equal, as well as the 163 angle is equal to the y angle. Hope this helps with more than just this problem!

A merchant bought a dozen of books for 1500 birr and sold it at a profit of 15% of its cost price. What is the selling price?
Answer: They sold each book at a price of 143.75 birr
Step-by-step explanation:
1500 divided by 12 is 125 and 15% of 125 is 18.75 so add it together and you got your answer. hope this helps <3
Answer:
C. 1725
Step-by-step explanation:
We can find the selling price by adding the cost price and the profit made
As the merchant has made 15% of profit on 1500 birr . So ,
15% of 1500 is 225 birr
[tex] \frac{x}{1500} \times 100 = 15 \: percent[/tex]
Adding the cost price and profit made we get ,
Selling Price = 1500 birr + 225 birr
Sp = 1725 birr

I need AC
Answer:
AC = 18
Step-by-step explanation:
Using the cosine ratio in the right triangle and the exact value
cos30° = [tex]\frac{\sqrt{3} }{2}[/tex] , then
cos30° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{AC}{AB}[/tex] = [tex]\frac{AC}{12\sqrt{3} }[/tex] = [tex]\frac{\sqrt{3} }{2}[/tex] ( cross- multiply )
2 AC = 12[tex]\sqrt{3}[/tex] × [tex]\sqrt{3}[/tex] = 12 × 3 = 36 ( divide both sides by 2 )
AC = 18
∠ACB=90° ⇒ ΔABC is right triangle
AB is hypotenuse, ∠BAC=30° ⇒
[tex]CB=\dfrac{AB}{2}=\dfrac{12\sqrt{3} }{2} =6\sqrt{3}[/tex]
Let's use Pythagorean theorem
[tex]AB^2=BC^2+AC^2\\AC^2=AB^2-BC^2\\AC^2=(12\sqrt{3})^2-(6\sqrt{3} )^2\\AC=\sqrt{(12\sqrt{3}-6\sqrt{3})(12\sqrt{3}+6\sqrt{3}))} \\AC=\sqrt{6\sqrt{3}\times18\sqrt{3} } \\AC=\sqrt{3\times6\times18} \\AC=18[/tex]
A bootstrap sampling distribution was constructed for a single mean. The sample mean was 100 and the standard deviation was 15. Given a sample size of 30 the standard error was 2.739. If the sample size were increased to 500, how would the standard error change?
a. It would increase.
b. It would stay the same.
c. It would decrease.
Answer:
c. It would decrease
Step-by-step explanation:
When you increase the sample size, you decrease the standard/marginal error since you have a bigger representation of the population. However, this would take time and money to collect data for these big samples.

Alec and Beau race to compute 1 + 2 + 3 + ... + n. Alec skips two numbers and gets a sum of 92. Beau double-counts two numbers and gets a sum of 145. What is the value of n?
Answer:
n = {14, 15, 16}Step-by-step explanation:
This is a sum of the first n terms of an AP:
S = (1 + n)*n/2The true sum is between 92 and 145:
92 < n(n + 1)/2 < 145184 < n(n + 1) < 290184 < n² + n < 290185 < (n + 1/2)² < 291√185 < n + 1/2 < √29114 ≤ n < 17Let n = 14
S = 14*15/2 = 105Let n = 15
S = 15*16/2 = 120Let n = 16
S = 16*17/2 = 136How to Calculate discount rate
Answer:
[tex]\frac{i\times d}{100}[/tex]
Step-by-step explanation:
To calculate the discount, we multiply the initial amount (i) to the discount (d) and then divide that answer by 100. After we find that answer we then subtract it from the initial price.
For example:
A computer costs $695 and it has a 7% discount. Calculate the total costs of the computer after the 7% discount.
[tex]\frac{695\times7}{100} =695\times7=4865\div100=48.65[/tex]
[tex]695-48.65=646.35[/tex]
[tex]c=646.35[/tex]
The computer (after a 7% discount) costs "$646.35 dollars."
Hope this helps.
