Answer:

x = 1

Step-by-step explanation:

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

The correct description for the polar function, r = 6sin(θ) is: D. Circle symmetric on the line theta = 0, with a radius of 6.

In Mathematics, the relationship between the polar coordinates (r, θ) and rectangular coordinates (x, y) is given by these polar functions:

On the horizontal plane:

x = rcosθ

On the vertical plane:

y = rsinθ

Where:

In conclusion, the correct description for the polar function, r = 6sin(θ) is circle symmetric on the line with an angle (θ) equal to zero (0) and a radius of 6.

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.

Hope this helps! :)

From the calculations, Gerald will now have to pay the sum of $145.50 towards his monthly health insurance.

Note that the first sum being contributed by Gerald is (100%- 65%) of $345. This is 35% of $345 = $120.75

If his employer takes up 50% of $38, this leaves his contribution for dental as 50% of $38 = $19

Also if his employer takes up 75% of $23, his contribtuion for vision premium is 25% of 23 = $5.75

Hence his total contribution is now:
120.75 + 19.00 + 5.75 = $145.50

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.

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.

Step-by-step explanation:

to solve this we need to find how frequent pink is landed on. to find the frequency we add all the total

12+6+9+13=40

then we divide 6 (frequency of pink) by 40 to fing how frequent 6 is in percentage

6÷40=.15=15%

then we multiply 15% by 120

The completely factored form of f(x) = 6x³ - 13x² - 4x + 15 is f(x) = (x + 1)(2x - 3)(3x - 5)

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)
