(PLS HELP)The diameter of a cylindrical water tank is 12 ft, and its height is 14 ft. What is the volume of the tank?
Use the value 3.14 for л, and round your answer to the nearest whole number. Be sure to include the correct unit in your answer.
Solution:
First, let's find the radius with the given diameter.
⇒ Diameter = 2(Radius)
⇒ 12 ft = 2(Radius)
⇒ 6 ft = Radius
The area of the cylinder is basically the area of a circle in the cylinder multiplied by the height of the cylinder. This means that the volume of the cylinder is πr²h. Now, let's find the volume of the cylinder.
⇒ πr²h = Volume of cylinder
⇒ (3.14)(6²)(14) = Volume of cylinder
⇒ (3.14)(36)(14) = Volume of cylinder
⇒ 1582.56 ft³ = Volume of cylinder
Volume:-
[tex]\\ \rm\rightarrowtail \pi (6)^2(14)[/tex]
[tex]\\ \rm\rightarrowtail \pi 252(2)[/tex]
[tex]\\ \rm\rightarrowtail 504\pi [/tex]

Answer:
x=6
Step-by-step explanation:
By the Product Rule of Logarithms, the logarithm of the product of numbers is the sum of the logarithms of the numbers.
[tex] log(x) + log(x - 1) = log(x(x - 1)) = log( {x}^{2} - x ) = log(3x + 12) [/tex]
Raise both sides to the power of 10 to eliminate the logs, obtaining:
[tex] {x}^{2} - x = 3x + 12[/tex]
[tex] {x}^{2} - 4x - 12 = 0[/tex]
[tex](x - 6)(x + 2) = 0[/tex]
x = -2 or x = 6. Since x = -2 is extraneous, it follows that x = 6.

A swimming pool has a volume of 40,075 cubic feet. How many gallons of water does the pool hold
Answer:
299,781.8 gallons
Step-by-step explanation:
There are 576/77 gallons of water in one cubic foot, so the volume of the pool is ...
(40075 ft³)(576/77 gal/ft³) = 3297600/11 gal ≈ 299,781.8 gal
The pool holds about 299,781.8 gallons.

A few students finished up their NCVPS work early and are playing skip
rope. As the rope rotates it is observed that its maximum height is 2.75m
after 1 second. The first minimum height of 0.25m occurs 2 seconds after
the maximum height. Sketch a graph to model the situation.
Answer:
see attached
Step-by-step explanation:
The graph can be shown as a sine wave with a maximum of 2.75 m and a minimum of 0.25 m. Its period will be twice the time from maximum to minimum, so will be 2×2 seconds = 4 seconds. The midline of the graphed function will be halfway between the extremes, at 1.5 m.
The equation of the graph will put the first peak at 1 second, so if a cosine function is used, it will have a horizontal shift of 1 second to the right.

Esther cycles 70 miles over 4 days.
On day 1 she cycles 14 miles.
On day 2 she cycles 32 km.
On day 4 she cycles twice as far as she does on day 3
How far does she cycle on day 4?
Give units with your answer.
Answer:
16
Step-by-step explanation:
70 - 14 - 32 = 24 (Which is the amount of miles she cycled on both Day 3 and 4)
x + x*2 = 24
8 + 8*2 = 24
8 + 16 = 24
Therefore, she cycles 24 miles on Day 4.
A store is having a sale in which all bookbags are discounted by `30\%`. Mai has a coupon for `\$5` off the regular price of one bookbag. The store first applies this coupon, and then takes `30\%` off the reduced price. Mai pays `\$23.10` for the bookbag.
You said the equation represents this scenario, and the solution to your equation was `\$35.56`.
Explain what the solution to the equation means within the context of the problem.
The regular price of the book bag was $38.
EquationAn equation is an expression that shows the relationship between two or more numbers and variables.
Let x represent the regular price of the bag. After applying the coupon:
Price = x - 5
After the discount:
23.10 = (x - 5) - 30% of (x - 5)
23.10 = (x - 5) - (0.3x - 1.5)
0.7x - 3.5 = 23.10
x = 38
The regular price of the book bag was $38.

What is f(5) if f(1) = 3. 2 and f(x 1) = Five-halves(f(x))?
Function assign value from one set to another. The value of f(5), if f(1) = 3.2 and f(x+1) = Five-halves(f(x)) is 125.
What is Function?A function assigns the value of each element of one set to the other specific element of another set.
As it is given the value of the function f(1) is 3.2, while the value of f(x+1) is [tex]f(x+1) = \dfrac{5}{2}[f(x)][/tex], therefore, in order to find the value of f(5), we need to calculate the value of f(4).
f(2)
[tex]f(x+1) = \dfrac{5}{2}[f(x)]\\\\f(2)=f(1+1) = \dfrac{5}{2}[f(1)]\\\\f(2) = 2.5 \times 3.2\\\\f(2) = 8[/tex]
f(3)
[tex]f(x+1) = \dfrac{5}{2}[f(x)]\\\\f(3)=f(2+1) = \dfrac{5}{2}[f(2)]\\\\f(3) = 2.5 \times 8\\\\f(3) = 20[/tex]
f(4)
[tex]f(x+1) = \dfrac{5}{2}[f(x)]\\\\f(4)=f(3+1) = \dfrac{5}{2}[f(3)]\\\\f(4) = 2.5 \times 20\\\\f(4) = 50[/tex]
f(5)
[tex]f(x+1) = \dfrac{5}{2}[f(x)]\\\\f(5)=f(4+1) = \dfrac{5}{2}[f(4)]\\\\f(5) = 2.5 \times 50\\\\f(5) = 125[/tex]
Hence, the value of f(5), if f(1) = 3. 2 and f(x+1) = Five-halves(f(x)) is 125.

A taxi ride costs $3 plus $2.50 per mile. Write and graph an equation that represents the total cost of a taxi ride. Let m represent number of miles and c represent the total cost (in dollars) of the taxi ride. What is the total cost of a five-mile taxi ride?
Answer:
The answer is 3 + 2.50m = c.
Step-by-step explanation:
You would use the slope equation: y = mx+b where y is equal to the total cost of a taxi ride, in dollars and m is equal to the number of miles. $3 is your base cost which represents your y-intercept or your b and $2.50 represents your slope.

Answer:
[tex]\sf\: Area \: of \: the \: triangle \: = \boxed{\boxed{\bf\:50 \: cm^{2}}}[/tex]
Step-by-step explanation:
Given,
The triangle is an isosceles triangle.
Base (b) = 10 cmHypotenuse = 13 cmAltitude (h) = Base = 10 cm [isosceles triangle has equal opposite sides]Since, we are given the hypotenuse, the triangle will be an isosceles right angled triangle.
We know that, area of a right angled triangle = ½ × b × h
By substituting the values in the above formula...
½ × b × h
= ½ × 10 × 10
