Considering the given linear function, it is found that table B represents the situation.

A linear function is modeled by:

\(y = mx + b\)

In which:

In this problem, the function is given by:

y = 2x + 30.

Hence, the y-intercept is of b = 30, that is, when x = 0, y = 30, and the slope of m = 2 means that when x increases by 1, y increases by 2, hence table B is the answer for this question.

Answer:

Luke has earned $9 in interest after one year.

Step-by-step explanation:

To calculate how much money Luke has earned in interest after one year, we can use the formula for simple interest:

I = P * r * t

where:

I is the interest earned

P is the principal (the initial amount of money)

r is the interest rate expressed as a decimal

t is the time period in years

In this case, we have:

P = $600 (the initial amount of money)

r = 0.015 (1.5% interest rate expressed as a decimal)

t = 1 (one year)

Plugging these values into the formula, we get:

I = $600 * 0.015 * 1 = $9

Therefore, Luke has earned $9 in interest after one year.

For more help:

Here are the steps to calculate how much money Luke has earned in interest after one year:

Step 1: Identify the given information

Read the problem carefully and identify the relevant information. In this case, we are told that Luke checks his bank account and finds that he has $600 in it. We are also given that he is earning 1.5% interest per year on this account.

Step 2: Identify the formula to use

The formula for simple interest is:

I = P * r * t

where:

I is the interest earned

P is the principal (the initial amount of money)

r is the interest rate expressed as a decimal

t is the time period in years

In this case, we are given the values of P, r, and t, so we can use this formula to calculate the interest earned.

Step 3: Plug in the values

Now we can plug in the values that we identified in Step 1 into the formula from Step 2.

I = P * r * t

I = $600 * 0.015 * 1

Simplifying the right-hand side:

I = $9

Step 4: Interpret the answer

The final answer is $9, which represents the interest earned by Luke on his $600 bank account after one year.

The total surface area of the solid shape made from the cube and cylinder is approximately 583.31 cm².

The side length of the cube is 8.7 cm, so the surface area of one face is A = 8.7²

= 75.69 cm²

Since there are six faces, the total surface area of the cube is 6 * 75.69 = 454.14 cm²

Since there are two circular bases, the total surface area of the bases is 2 * 22.91 = 45.82 cm².

In this case, the radius of the cylinder is 2.7 cm and the height is 4.9 cm, so the curved surface area is A_curved = 2 * π * 2.7 * 4.9 ≈ 83.35 cm².

Total surface area = surface area of the cube + surface area of the cylinder

Total surface area = 454.14 cm² + 45.82 cm² + 83.35 cm²

Total surface area ≈ 583.31 cm²

Answer:

x = 0 , x = 2

Step-by-step explanation:

3x² = 6x ( subtract 6x from both sides )

3x² - 6x = 0 ← factor out 3x from each term

3x(x - 2) = 0

equate each factor to zero and solve for x

3x = 0 ⇒ x = 0

x - 2 = 0 ( add 2 to both sides )

x = 2

solutions are x = 0 , x = 2

The vertical displacement is of 2 units down, the correct option is B.

Remember that for a function f(x), a vertical displacement of N units is written in general form as:

g(x) = f(x) + N

If N > 0, the translation is upwards.

if N < 0, the translation is downwards.

Here we assume that we start with the parent cosine function:

y = cos(x)

And the transformed function is:

y = -2 - cos(x - π)

So we have some transformations, but the vertical translation is of 2 units down. So the correct option is B.

An inequality to represent the dollar amounts d in cash and prizes Regan can win is p + d ≥ 500.

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

Given that, Regan won the grand prize at a store giveaway. The grand prize winner is guaranteed to win at least $500 in cash and prizes.

Let d represent the amount of cash in dollars and p represent the amount of prizes.

Since the  grand prize winner is guaranteed to win at least $500,

No, the rank of the product of two n by n square matrices A and B, denoted as AB, cannot be less than n-1 if both A and B have ranks of n-1.

According to the Rank-Nullity theorem, for any matrix M, the sum of its rank and nullity is equal to the number of columns in M. In this case, the number of columns in AB is n, so the sum of the rank and nullity of AB must be n.

If rank(A) = rank(B) = n-1, it means that both A and B have nullity 1. The nullity of a matrix is the dimension of its null space, which consists of all vectors that get mapped to the zero vector when multiplied by the matrix. Since both A and B have rank n-1, their null spaces consist only of the zero vector.

Now, considering AB, if the rank of AB were less than n-1, it would mean that the nullity of AB is greater than 1.

However, this would violate the Rank-Nullity theorem since the sum of the rank and nullity of AB must be n, which is the number of columns.

Therefore,  if rank(A) = rank(B) = n-1, the rank of AB cannot be less than n-1.

Answer:

The cost of printing 142 more posters when 18 has already been printed is $5.57.

Step-by-step explanation:

We are given that the marginal cost (dollars) of printing a poster when x posters have been printed is given by the following equation C'(x)=x^-3/4.

The given equation is: \(C'(x) = x^{\frac{-3}{4} }\)

The cost of printing 142 more posters when 18 have already been printed is given by;

Integrating both sides of the equation and using the limits we get;

\(\int_{a}^{b} C'(x) dx=\int_{18}^{142} x^{\frac{-3}{4}}dx\)

As we know that  \(\int\limits {x}^{n} \, dx = \frac{x^{n+1} }{n+1}\) , so;

          =  \(\frac{x^{\frac{-3}{4}+1 } }{\frac{-3}{4}+1 } ]^{142} __1_8\)

          =  \(\frac{x^{\frac{1}{4} } }{\frac{1}{4} } ]^{142} __1_8\)

          =  \(4[x^{\frac{1}{4} } } ]^{142} __1_8\)

          =  \(4[(142)^{\frac{1}{4} }- (18)^{\frac{1}{4} }} ]\)

          =  $5.57

Hence, the cost of printing 142 more posters when 18 has already been printed is $5.57.

Step-by-step explanation:

The guests in the birthday party ate 33 cookies.

We know that Mrs. Smith made 6 1/4 dozen cookies and there were 3 1/2 dozen cookies left.

Let's first convert these fractions to a common denominator of 4, so we can easily subtract them.

6 1/4 dozen = 25/4 dozen

3 1/2 dozen = 14/4 dozen

Now we can subtract the number of cookies that were left from the number of cookies that were made:

25/4 - 14/4 = 11/4 dozen

To find out how many cookies this represents, we need to multiply by the number of cookies in one dozen.

There are 12 cookies in one dozen, so:

11/4 x 12 = 33

Therefore, the guests ate 33 cookies.
