Step-by-step explanation:

A multiplier of 1.2 means the value is multiplied or increased by a factor of 1.2.

A multiplier is a term used to represent a factor by which a value is multiplied or increased. It is a numeric value that indicates the extent of the increase or expansion of a given quantity. Multiplication by a multiplier results in scaling or changing the magnitude of the original value.

A multiplier of 1.2 indicates that a value will be increased by 20% or multiplied by a factor of 1.2. This means that when the multiplier is applied to the original value, the resulting value will be 1.2 times the original.

Answer: YES, Its correct.

\(M_x=\frac{-6+2}{2}=2\\\\M_y=\frac{-3+7}{2}=2\\\\M=(2,2)\)

Answer:

(-2,2)

Step-by-step explanation:

The midpoint is the middle of the line. So, you can take it step-by-step and look at the individual numbers.

Between -6 and 2, that is 8 spaces. So, the middle would be four spaces from one of those numbers. Therefore, X-COORDINATE = -2

Between -3 and 7, that is 10 spaces. So the middle would be 5 spaces from one of those numbers, Therefore, Y-COORDINATE = 2

So, the midpoint would be (-2,2)

Answer:

  XED is 2

  demand will likely be based on price

Step-by-step explanation:

You want the XED for Coke and Pepsi, given that a decrease in price of Pepsi from $2 to $1.75 per liter causes demand for Coke to fall from 6,000 to 4500 liters.

XED is the abbreviation for "cross-elasticity of demand." It is the ratio of the percentage change in the demand for one good to the percentage change in price for another.

  XED = (∆Q/Q)/(∆P/P)

  XED = ((4500 -6000)/(6000))/((1.75 -2.00)/(2.00)) = (2/6000)(-1500/-0.25)

  XED = 2

The XED is positive for substitute goods, and negative for complementary goods (bought together).

The relatively large positive XED for Coke and Pepsi indicates these brands are nearly interchangeable. Consumers will tend to choose one over the other based on price. Apparently, the price of $1.75 per liter of Pepsi is sufficiently low to cause a switch from Coke.

Answer:

3. GK = 9 cm

4. A = 4√65 cm^2

Step-by-step explanation:

Given:

Rectangle FGHK

FH = 9 cm

FG = 4 cm

Find: GK - ?, A (area) - ?

3. Diagonals of a rectangle are of equal length

FH = GK = 9 cm

4. We need to find the longer side length of the triangle (we can use the Pythagorean theorem from ∆FGH or ∆FHK, since they are right triangles):

\( {gh}^{2} = {fh}^{2} - {fg}^{2} \)

\( {gh}^{2} = {9}^{2} - {4}^{2} = 81 - 16 = 65\)

\(gh > 0\)

\(gh = \sqrt{65} \: cm\)

Now, we can find the area:

\(a = \sqrt{65} \times 4 = 4 \sqrt{65 \: {cm}^{2} } \)

Answer: a₉ = 327,680

Step-by-step explanation:

This seems to be a geometric sequence.

The recursive relation for this type of sequence is:

aₙ = aₙ₋₁*r

Where r is a constant.

Then we also have:

aₙ/aₙ₋₁ = r.

then we can find the value of r if we take the quotient of different consecutive terms, for example, the quotient of the second and firs term is:

r = 20/5 = 4

And the quotient between the third and second term is:

r = 80/20 = 4

Then we can conclude that r  = 4.

And also, the n-th term of this sequence can be written as:

aₙ = a₁*r^(n - 1)

such that:

a₁ = 5

r = 4

Then the n-th term of this sequence is:

aₙ = 5*(4)^(n - 1)

Then the term a₉ can be found if we just replace n by 9 in the above equation:

a₉ = 5*(4)^(9 - 1) = 5*(4)^(8) = 327,580

Answer:

a) \(p \geq 60\,ft^{2}\), b) \(w \geq 36\,ft\), c) \(1\,qt \leq q \leq 2\,qt\), d) \(0.70\cdot p + 0.10\cdot w + 8\cdot q \leq 65\)

Step-by-step explanation:

In this question we proceed to translate each sentence into mathematical language and, more specifically, inequations:

a) At least 60 square feet of plywood for the surface

Let \(p\) the surface area of plywood, measured in square feet, and the inequation is:

\(p \geq 60\,ft^{2}\) (Eq. 1)

b) At least 36 feet of wood planks for the frame of the dog house

Let \(w\) the total length of wood planks, measured in feet, and the inequation is:

\(w \geq 36\,ft\) (Eq. 2)

c) Between 1 and 2 quarts of paint

Let \(q\) the total capacity of paint, measured in quarts, and the inequation is:

\(1\,qt \leq q \leq 2\,qt\) (Eq. 3)

d) Han's budget is $ 65. Plywood costs $ 0.70 per square foot, planks of wood cost $ 0.10 per foot and paint costs $ 8 per quart.

Dimensionally speaking, we understand that cost equals unit cost multiplied by physical variable (i.e. Area, length or capacity). Let \(p\), \(w\) and \(q\) the surface area of plywood, the total length of wood planks and the total capacity of paint, respectively. The sentence is represented by the following inequation:

\(0.70\cdot p + 0.10\cdot w + 8\cdot q \leq 65\) (Eq. 4)

Write an inequality to represent each constraint(material and cost)

Plywood:

plywood ≥ 60 square feet

Planks:

planks ≥ 36 feet

Paints

1 quarts ≤ paints ≤ 2 quarts

Inequality to represent cost constraint

Plywood = $0.70

planks of wood = $0.10

paint costs $8

Total cost = $65

0.70 × p + 0.10 × pw + 8 × Pa ≤ 65

0.70p + 0.10pw + 8pa ≤ 65

The greatest number of people that they may invite and still stay within their budget is 130 people.

The standard form of a linear equation is given by:

y = mx + b

Where y is a dependent variable, x is an independent variable, m is the slope of the line (the rate of change), b is the y intercept (that is the initial value of y).

Let y represent the budget for x number of people.

Since the reception hall charges a $80 cleanup fee plus $34 per​ person, hence this can be represented by the function:

y = 34x + 80

They have budgeted $4,500 for their reception. Therefore the greatest number of people can be found from:

4500 = 34x + 80

34x = 4420

x = 130 people

Therefore the greatest number of people that they may invite and still stay within their budget is 130 people.

Stephen makes the mistake in the expression as he uses the 4 in the root and the 3 in the power and the expression actually is: ∛(16)/e

We start with the expression:

exp( (4/3)*ln(2) - 1)

Here we can use that:

exp(ln(x)) = x.

and e^(a + b) = e^a*e^b.

the first step here is:

e^((4/3)*ln(2) - 1) = e^((4/3)*ln(2)*e^(-1)

So the first step of Stephen is correct, but the first step of Helen is not, you can not simplify the expression in that way.

now, we have that:

a*ln(x) = ln(x^a)

then we can write:

(4/3)*ln(2) = ln(2^(4/3))

and e^(ln(2^(4/3)) = 2^(4/3)

then we have:

e^((4/3)*ln(2)*e^(-1) = 2^(4/3)/e

now we can write this as:

∛(2^4)/e

Here is where Stephen makes the mistake, he uses the 4 in the root and the 3 in the power.

Answer:

Step-by-step explanation:

What is the measure of angle IJK?

To find the measure of angle IJK, we need to use the fact that the sum of the angles in a triangle is 180 degrees. We can start by finding the measure of angle KJH, which is 180 - 84 - 50 = 46 degrees.

Next, we can use the fact that angles IJH and IJK are vertical angles (opposite angles formed by the intersection of two lines), so they have the same measure. We know that angle IJH has a measure of 84 degrees, so angle IJK also has a measure of 84 degrees.

Therefore, the measure of angle IJK is 84 degrees.

Based on the graph, the following statements are true:

A. The domain is the set of all real numbers.

D. The range is the set of all real numbers greater than or equal to zero.

The graph demonstrates that the function will always produce a real number larger than or equal to zero regardless of the real number used as an input. The set of all real numbers constitutes the domain, whereas the set of all real numbers larger than or equal to zero constitutes the range. The other two claims are false. The range is neither the set of all real numbers, nor is the domain restricted to real numbers larger than or equal to zero.

The given parameters are

The total number of people is

n = 20

2 of the 20 people are to be selected.

So, the number of selection is

\(n = ^nC_r\)

This gives

\(n = ^{20}C_2\)

The expression that represents both students being sophomore is

\(n = ^{6}C_2\) --- i.e. 2 students selected from 6
