Answer:
The answer is 37.
Step-by-step explanation:
Step 1: To find the output, k, we need to substitude 3 into the equation for t.
Step 2: k = 13t - 2
k = 13 x 3 - 2
= 39 - 2
= 37
Step 3: When the input is 3, the output is 37.
A cylindrical gas tank has a volume
of 1,808.64 m². Its height is 9 m. What is its radius?
Answer:
The radius is 32
Step-by-step explanation:
V= πr2h
So,
3.14(18)(x)=1808.64
56.52x=1808.64

The height of a single car on a Ferris wheel is modeled by a cosine function.
The car completes 4 whole rotations in a time period of 27 minutes.
Write a function rule that could model this situation?
The cosine function that can model this real-world scenario is:
f(x) = -106cos (4x) + 106. See how the same is derived below. The full question is also attached.
A Cosine Function is a periodic function that is denoted as Cos x. See the attached image.
The above function is derived as follows:
T = 2π/4 = π/2 = 2π/ω
Therefore, ω = 2π/π/2 = 4
This means f(x)= -106 cos (4x) + 106

Step-by-step explanation:
When y is 4, p is 0. 5, and m is 2, x is 2. If x varies directly with the product of p and m and inversely with y, which equation models the situation?
x p m y = 8
StartFraction x y Over p m EndFraction = 8
StartFraction x p m Over y EndFraction = 0. 5
StartFraction x Over p m y EndFraction = 0. 5
Answer:
[tex]\dfrac{xy}{pm}=8[/tex]
Step-by-step explanation:
If x varies directly as the product of p and m, and inversely with y, the relation can be written ...
x = k(pm)/y . . . . where k is the constant of proportionality
__
This can be solved for k:
k = xy/pm
For the given values, the value of k is ...
k = (2)(4)/((0.5)(2)) = 8
Then the relation between the variables can be written ...
(xy)/(pm) = 8

Which statement(s) are true based on the pythagorean identities? sine squared (theta) = 1 cosine squared theta 1 = secant squared theta minus tangent squared theta cotangent squared theta = cosecant squared theta minus 1 1 minus tangent squared theta = negative secant squared theta negative cosine squared theta = sine squared theta minus 1
The statement that is true based on the Pythagorean identities is cotangent-squared of theta - cosecant-squared of theta = -1.
Why is the equation above true?Note that cotangent-squared of theta - cosecant-squared of theta = -1. is tru because it is the only equation that is correct.
So therefore, cotangent-squared of theta - cosecant-squared of theta = -1.

consuela is displaying a cylindrical case on a pedestal. she wants it to be placed so that there is an even amount of space on either side of the case. if the volume of cylinder shown is 1,130.97 cubic inches, how much space will be on either side if its placed on a pedestal that is 18 inches across? round to the nearest inch
The space that will be on either side if its placed on the pedestal of the cylinder that is 18 inches across will be 4.47 inches.
How to compute the dimension?It should be noted that the volume of a cylinder is given as:
= πr²h
We'll then slot the values given into the formula. This will be:
Volume = πr²h
1130.97 = (3.14 × r² × 18)
1130.97 = 56.52r²
r² = 1130.97/56.52
r² = 20
r = ✓20
r = 4.47
In conclusion, the space will be 4.47 inches.

What is the completely factored form of f(x) = 6x3 – 13x2 – 4x 15? (x 1)(6x2 – 19x 15) (x 1)2(2x – 3) (x 1)(3x – 2)(5x – 3) (x 1)(2x – 3)(3x – 5)
The completely factored form of f(x) = 6x³ - 13x² - 4x + 15 is f(x) = (x + 1)(2x - 3)(3x - 5)
How to factor the expression?The expression is given as:
f(x) = 6x³ - 13x² - 4x + 15
Expand the expression
f(x) = 6x³ - 19x² + 6x² + 15x - 19x + 15
Rewrite as:
f(x) = 6x³ + 6x² + 15x- 19x² - 19x + 15
Factorize the equation
f(x) = (x + 1)(6x²- 19x + 15)
Expand (6x² - 19x + 15)
f(x) = (x + 1)(6x² - 10x - 9x + 15)
Factorize the expression
f(x) = (x + 1)(2x - 3)(3x - 5)
Hence, the completely factored form of f(x) = 6x³ - 13x² - 4x + 15 is f(x) = (x + 1)(2x - 3)(3x - 5)

Which piecewise function represents the graph?
Answer:
D
Step-by-step explanation:
If you look at the right side of each piecewise function, you will see the x-values. That is what we will be focusing on in this explanation. All four equations have x > 4, and we know that to be true. If you look at the equation on the graph going South West, you will see that the endpoint is at x=1. Only 1 equation, D, has this in the piecewise function. To confirm it is D, you can see that 1<x<4 is also in the piecewise function, and all the values line up with their corresponding y-values.
