The amount of State withholding tax is, $20.65 and the amount of Federal withholding tax is, $17.7.

A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.

Assuming the State withholding tax to be 7% and the Federal withholding tax to be 6%.

Given, A  person made $295 last week.

Therefore, The amount of Federal withholding tax is,

= $(6/100)×295.

= $17.7.

And, The amount of State withholding tax is,

= (7/100)×295.

= $20.65

Function transformation rules are a set of rules that can be applied to a basic function in order to transform or modify its graph. These rules include:

1. Vertical translation: adding or subtracting a constant to the function. This shifts the graph up or down without changing its shape.

2. Horizontal translation: replacing x with x + c. This shifts the graph left or right without changing its shape.

3. Vertical scaling: multiplying the function by a constant. This stretches or compresses the graph vertically.

4. Horizontal scaling: replacing x with kx. This stretches or compresses the graph horizontally.

5. Reflection: reflecting the graph across the x-axis or y-axis. This changes the orientation of the graph.

6. Composition: combining two or more functions to create a new function.

These rules allow mathematicians to manipulate and analyze functions in order to better understand their properties and behavior. By applying these rules to a basic function, mathematicians can create a variety of related functions with different features and behaviors.

All 4 helpers will be at the clinic on the same day 7 times in 12 weeks.

What is Prime Factorization?

"Prime Factorization" is the process of determining which prime numbers multiply together to get the original number.

To find the number of times in 12 weeks that all 4 helpers will be at the clinic on the same day, we need to find the least common multiple (LCM) of the numbers 4, 6, 2, and 3.

First, we can find the prime factorization of each number:

4 = 2 x 2

6 = 2 x 3

2 = 2

3 = 3

Next, we can find the LCM by taking the highest power of each prime factor that appears in the factorizations:

LCM = 2 x 2 x 3 = 12

Therefore, all 4 helpers will be at the clinic on the same day every 12 days. Since 12 weeks is equivalent to 84 days, we can divide 84 by 12 to get the number of times:

84 ÷ 12 = 7

So, all 4 helpers will be at the clinic on the same day 7 times in 12 weeks.

g(x) = 2^x

(0, 1), (1, 2), (2, 4), (3, 8), ...

If the price elasticity of demand is equal to 0.02/0.1, then the demand for apples is inelastic and if the price elasticity of demand is equal to 0.2/5, then the demand for apples is elastic.

The price elasticity of demand is calculated using the midpoint method with formula:

Price Elasticity of Demand = (Percent Change in Quantity Demanded) / (Percent Change in Price)

The value of the price elasticity of demand tells us whether the demand for a product is elastic (sensitive to price changes), inelastic (insensitive to price changes), or unitary elastic (neither elastic nor inelastic). A value of price elasticity of demand greater than 1 indicates that the demand for the product is elastic, meaning that a small change in price leads to a large change in the quantity demanded. A value of price elasticity of demand less than 1 indicates that the demand for the product is inelastic, meaning that a small change in price leads to a small change in the quantity demanded.

If the price elasticity of demand is equal to 0.02/0.1, then the demand for apples is inelastic between points X and Y, meaning that a small change in price leads to a small change in the quantity demanded. If the price elasticity of demand is equal to 0.2/5, then the demand for apples is elastic between points X and Y, meaning that a small change in price leads to a large change in the quantity demanded.

Simpson's 1/3rd rule is a method of numerical integration that is used to approximate the value of a definite integral.

It is based on the idea of approximating the area under a curve by dividing it into a series of trapezoids and calculating the area of each trapezoid. The formula for Simpson's 1/3rd rule is:

∫abf(x)dx ≈ (b-a)/6 [f(a) + 4f((a+b)/2) + f(b)]

In this formula, a and b are the limits of integration, and f(x) is the function being integrated. The rule is called the "1/3rd rule" because the coefficient of the middle term is 4/3, which is equal to 1/3 when multiplied by the 3 in the denominator.

To use Simpson's 1/3rd rule, you first need to divide the interval [a,b] into an even number of subintervals. Then, you can apply the formula to each subinterval to get an approximation of the integral over that subinterval. Finally, you can add up the approximations for each subinterval to get an approximation of the integral over the entire interval.

Simpson's 1/3rd rule is a more accurate method of numerical integration than the trapezoidal rule, but it is still an approximation. The accuracy of the approximation depends on the number of subintervals used and the smoothness of the function being integrated.

The measures of the numbered angles in rhombus DEFG are m ∠ 1 = m ∠ 2 = m ∠ 4 = 27°, m ∠ 3 = 90° and m ∠ 5 = m ∠ 6 = 63°

A flat shape with 4 straight sides that are all equal length. Also opposite sides are parallel and opposite angles are equal. It is a type of parallelogram.

Given is a rhombus DEFG, we need to find the measures of the numbered angles,

We know that, diagonals of a rhombus bisect each other at right angle, and also bisects the vertex angles,

Also, the opposite angles are equal,

Therefore,

m ∠ 1 = m ∠ 2 = m ∠ 4 = 27°

m ∠ 3 = 90°

m ∠ 5 = m ∠ 6 = 90° - m ∠ 1

m ∠ 5 = m ∠ 6 = 90° - 27° = 63°

m ∠ 5 = m ∠ 6 = 63°

Hence, the measures of the numbered angles in rhombus DEFG are m ∠ 1 = m ∠ 2 = m ∠ 4 = 27°, m ∠ 3 = 90° and m ∠ 5 = m ∠ 6 = 63°

The equation model is defined as the model of the given situation in the form of an equation using variables and constants.

We can use algebra to solve this problem. Let x be the number of miles Jim drove the truck. Then the total cost can be represented as:

15.99 + 0.86x = 206.91

To find the number of miles driven, we can subtract the base fee from both sides of the equation:

15.99 + 0.86x - 15.99 = 206.91 - 15.99

0.86x = 190.92

Answer:

              An equation to represent the given geometric sequence would be [tex]a(x)=5*3^{x-1}[/tex], and a(8) of the geometric sequence will be 10,935.

Step-by-step explanation:

              In order to write an equation for a geometric sequence, first we must analyze the sequence to find its starting value and its constant ratio. The starting value is simply the first term in the sequence, which is 5. As for the constant ratio, it is the rate of change that the equation uses. In this sequence, the constant ratio is 3. Now, we can write out an equation for this geometric sequence.

              We know the first term of the sequence is 5, and the common ratio is 3, so we can write out a function for the geometric sequence, which will be [tex]a(n)=5*3^{n-1}[/tex]. NOTE that the exponential power is n - 1, and not n. This is because the first term of the sequence is 5, and not the "0th" term, therefore we must subtract 1 from n (the term number) to have the right sequence.

              Lastly, we can use the equation [tex]a(n)=5*3^{n-1}[/tex] to find the 8th term of the sequence by replacing n with 8. So [tex]a(x)=5*3^{n-1}[/tex] would become [tex]a(8)=5*3^{8-1}[/tex], and you will get [tex]a(8)=5*3^{8-1}[/tex] ⇒ [tex]a(8)=5*3^{7}[/tex] ⇒ [tex]a(8)=5*2187[/tex] ⇒ [tex]a(8)=10,935[/tex]. Therefore, the equation for the nth term of the geometric sequence would be [tex]a(n)=5*3^{n-1}[/tex], and the 8th term of the sequence is 10,935.

The two solutions of the linear equation are:

(0, 2)

(3, 1)

And a coordinate pair that is not a solution is:

(0, 5)

Here we have the linear equation:

x + 3y = 6

And we want to find two ordered pairs that are solutions.

To find them,wecan evaluate in two values of x and then find the correspondent values of y.

if x = 0

0 + 3y = 6

y = 6/3 = 2

if x = 3

3 + 3y = 6

3y = 6 - 3

3y = 3

y = 3/3 = 1

Torr and mmHg are two units of pressure that are often used interchangeably. In fact, 1 mmHg is equal to 1 torr, which means that they are equivalent units of measurement.

To convert torr to mmHg, you can simply multiply the pressure value in torr by 1, since 1 torr is equivalent to 1 mmHg. For example, if you have a pressure of 760 torr, you can convert it to mmHg as follows:

760 torr x 1 mmHg/torr = 760 mmHg

Therefore, 760 torr is equivalent to 760 mmHg. Alternatively, you can also convert mmHg to torr by dividing the pressure value in mmHg by 1. For example, if you have a pressure of 760 mmHg, you can convert it to torr as follows:

760 mmHg ÷ 1 mmHg/torr = 760 torr

Therefore, 760 mmHg is equivalent to 760 torr.
