The trigonometric function, Y = -4·cos 5·x - 10 is undefined at Y = 0, but the function arranged as Y = -4·cos(5·x - 10) has an x-intercept at x = π/10 + 2

A trigonometric function indicates the relationship between angles and the lengths of sides of angles.

The specified function can be presented as follows;

Y = -4·co(5·x) - 10

There are two unknown variables

The number of equations is one

The function, at Y = 0, can be evaluated as follows;

Y = 0 = -4·co(5·x) - 10

cos(5·x) = 10/(-4) = -2.5

5·x = arccos(-2.5) = Undefined

However, when the function is; Y = -4·cos((5·x) - 10), we get;

At Y = 0

0 = -4·cos((5·x) - 10)

cos((5·x) - 10) = 0/(-4) = 0

5·x - 10 = arccos(0) = π/2

Therefore;

x = (π/2 + 10)/5 = π/10 + 2

(-π/2 + 10)/5

An x-intercept is at x = π/10 + 2

The diameter of the circle is 30 feet.

What is diameter?

The center of the circle is the midpoint of a line segment that connects two points on the circle's perimeter, and this line segment is indicated by the diameter of a circle.

The diameter of a circle is precisely equal to twice the radius' length.

Let us suppose the diameter of a circle is D then, the area is computed according to the formula

[tex]A = \frac{\pi D^2}{4}[/tex]

where

A is the area and D is the diameter.

Plug A = 225 pi in the above equation,

[tex]225 \pi =\frac{\pi D^2}{4} \\225 = \frac{D^2}{4} \\D^2 = 900\\D = 30[/tex]

The formula for D2 to be placed in order to find the unit price is D2 = B2/C2.

What is the unit price?

The average price of a product is calculated by dividing the total sales revenue by the total units sold. Managers must define "comparable" units when a single product is sold in variants, such as bottle sizes.

To find the unit price of an object, You divide the price by the Object. We need to find how much an object cost per unit.

Let, us consider an Example we have 50lbs of Kulfi (Object) that cost 8.00 dollars(price).

To find the Unit cost, We take the 8.00 and divide it by 50, which results in 0.16 cents per pound. We can check this by multiplying 0.16 by 50=8.00

So, Object= Number of units in cell = C2

Price of Object = B2

Unit Price Formula = D2

Therefore, by considering the above example.,

Object = C2 = 50

Price = B2 = 8.00

D2 Formula= Price of Object/ Number of Units

Therefore, The formula for D2 to be placed in order to find the unit price is D2 = B2/C2.

1. When salt is dissolved in water, the chemical bond between the salt atoms is broken by the water molecule.

2. When a teaspoon of salt is added to water, the salt molecules fill any open places in the water. Since water is a fluid with atoms that may move around freely, when salt is dissolved in it, these open spaces are filled, making salt particles invisible.

What is Standard Deviation?

The standard deviation in statistics is a measure of the degree of variation or dispersion in a set of values. A low standard deviation implies that the values of the set tend to be near to the mean (also known as the expected value), whereas a high standard deviation shows that the values are spread out over a larger range.

Solution:

Mean weight (μ) = 53 pounds

Standard deviation (σ) = 6.2 pounds

The z-score for any given weight, 'X', is given by the following expression;

z = (X - μ)/σ

(i) P(X<53)

Since 53 pounds is exactly the mean weight, 50% of the dogs weight more than 53 pounds while 50% weight less than 53 pounds.

P(X<53) = 50.0%

(ii) P(X<46)

z = (46-53)/6.2

z = -1.12

this is equivalent to 15.2 percentile

P(X<46) = 15.2%

(iii) P(X>46)

P(X>46) = 100% - P(X<46) = 100% - 15.2%

The additive inverse of (-4x - 8)  is  4x+8.

What is Additive Inverse?

Additive inverse refers to any number that when added to the original number gives the result as zero. For instance, the additive inverse of 8 is -8 as 8 + (-8) = 0. It is possible to get the additive inverse of negative numbers too. For example, the additive inverse of -10 will be 10 as -10 + 10 = 0.

The additive inverse of any given number can be found by changing the sign of it. The additive inverse of a positive number will be a negative, whereas the additive inverse of a negative number will be positive. However, there will be no change in the numerical value except the sign. For example, the additive inverse of 8 is -8, whereas the additive inverse of -6 is 6.

The addition of a number and its additive inverse is equal to the additive identity.

The weekly income is of $15,000, while a month is composed by four weeks, hence the monthly income is of:

4 x $15,000 = $60,000.

Then the percentages of each expenses are applied to find the values, for example, 40% of that is for employee wages, hence:

The polynomial (A) f(x)=x³-2x²-3x+6 has the zeros 2, radical 3, and negative radical 3 thanks to the factor theorem.

A factor theorem is a tool used in mathematics to thoroughly factor polynomials.

It is a theorem that connects the polynomial's zeros and factors.

The factor theorem states that (x-a) is a factor of f(x) if f(a)=0 and f(x) is a polynomial of degree n 1 and 'a' is any real number.

So, the Factor Theorem states that P(k) must equal zero if (x - k) is a factor of polynomial P(x).

A polynomial function with the zeros 2, 3, and -3 is provided to us. As a result, we can set k = 2, 3, -3.

The Factor Theorem states that P(2), P(3,) and P(-3) must all equal 0.

Tests of each option reveal that only option A is accurate:

f(x) = x³ – 2x² – 3x + 6

Testing each of the three results in:

[tex]\begin{aligned}f(2) & =(2)^3-2(2)^2-3(2)+6 \\& =(8)-(8)-(6)+(6) \\& =0 \stackrel{\checkmark}{=} 0 \\f(\sqrt{3}) & =(\sqrt{3})^3-2(\sqrt{3})^2-3(\sqrt{3})+6 \\& =(3 \sqrt{3})-(6)-(3 \sqrt{3})+6 \\& =0=0 \\f(-\sqrt{3}) & =(-\sqrt{3})^3-2(-\sqrt{3})^2-3(-\sqrt{3})+6 \\& =(-3 \sqrt{3})-(6)+(3 \sqrt{3})+6 \\& =0=0\end{aligned}[/tex]
