Step-by-step explanation:

f(x)=3x-3

g(x)=-x^2+4,

f(2) = 3(2) -3 = 6-3 =3

g(-2) = -(-2)^2+4 = -4+4 = 0

f(2)-g(-2)= = 3-0 = 3

The answer is A.

An indefinite integral is a function that, when differentiated, equals the original function. It is denoted by ∫f(x)dx, where f(x) is the function to be integrated. An indefinite integral always has an arbitrary constant of integration, which is denoted by C. This is because the derivative of any constant is zero, so the derivative of ∫f(x)dx+C is still equal to f(x).

A definite integral is the limit of a Riemann sum as the number of terms tends to infinity. It is denoted by ∫

a

b

​

f(x)dx, where a and b are the limits of integration. A definite integral does not have an arbitrary constant of integration, because the limits of integration specify a unique value for the integral.

In other words, an indefinite integral is a family of functions that share the same derivative, while a definite integral is a single number.

Answer:

You have to pay 20%, it would cost you $4,400 for the year, and each month $367 would come out of your check.

Step-by-step explanation :

If your boss pays 80% of a $22,000 health plan per year you would have to pay 20% of that health plan.

To find out what you need to pay for this year, you must find 20% of 22,000.

0.20 * 22,000 = 4,400

You would have to pay $4,400 for this year.

To check this, we can divide 22,000 by 5 since 20% is 1/5.

22,000 divided by 5 = 4,400

If you wanted to find how much would come out of your check monthly, well, since you have to pay $4,400 this year and there are 12 months in a year you can divide by 12.

4,400 divided by 12 = 366 \(\frac{2}{3}\)

So you would basically have to pay $367 every month.

The answer is D: conjecture

The key words in the description are "look for a pattern and then form an educated guess." This suggests making a hypothesis or assumption based on the observed pattern, which is the definition of a conjecture.

The other answer choices are defined as follows:

A. conjugation - the act of changing a verb to agree with its subject

B. conjunction - a connecting word

C. congruence - the state of agreeing, matching, or coinciding

D. conjecture - an opinion or conclusion formed on the basis of incomplete information

So option D, conjecture, is the best match for forming an educated guess based on an observed pattern in induction.

Answer:

$951

Step-by-step explanation:

EOQ = Sqroot{(2*Annual Demand*Ordering cost)/Holding cost}

= Sqroot{(2*250*12*100)/(0.2*30)}

= 317 Units Approximately

Total Holding cost = Average Inventory * Holding cost per unit

= (EOQ/2)*Holding cost per unit

= (317/2)*(0.2*30)

= $951

So by knowing the holding cost and the percentage that it represents, we want to find the total cost of the masks. We will find that the cost is $150.

We know that the holding cost is 20% of the cost of a single mask, so if the cost of a mask is C, the holding cost is:

(20%/100%)*C = 0.2*C

And we know that this is equal to $30, so we get:

0.2*C = $30

Now we can solve this for C, the total cost of a mask:

C = $30/0.2 = $150.

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: 3,650 days

Step-by-step explanation:

In the Gregorian Calendar, a common year has 365 days. We are going to assume that a common year always has 365 days for the purposes of this problem.

If one day is 20 minutes, then let us multiply that by 365 days, giving us 7,300 minutes in 1 year. Let us then multiply 7,300 minutes by 10 years. That gives us 73,000 minutes. We know that (based on this problem) there are 20 minutes in 1 day, so we divide 73,000 minutes by 20 minutes. The final answer is 3,650 days.

Step-by-step explanation:

Given

\(y = -\frac{2}{3}x + 8\)

Point (4,-5)

Required

Determine the line equation

From the question, we understand that the line is parallel to \(y = -\frac{2}{3}x + 8\)

This implies that they have the same slope, m

A linear equation is:

\(y = mx + b\)

Where

\(m = slope\)

By comparison: \(y = mx + b\) and \(y = -\frac{2}{3}x + 8\)

\(m = -\frac{2}{3}\)

Next, we determine the line equation using:

\(y - y_1 = m(x - x_1)\)

Where

\((x_1,y_1) = (4,-5)\) and \(m = -\frac{2}{3}\)

\(y - (-5) = -\frac{2}{3}(x - 4)\)

\(y +5 = -\frac{2}{3}(x - 4)\)

When 1,493,600 is divided by 8 the quotient is 186,700.

To divide 1,493,600 by 8, you can follow these steps:

We have to write down the dividend (1,493,600) and the divisor (8).

Now start with the largest place value in the dividend (the leftmost digit) and perform the division.

Divide 1 by 8. Since 1 is smaller than 8, you move to the next digit.

Bring down the next digit (4) and combine it with the previous quotient (0). This gives you 04.

Divide 4 by 8. Since 4 is smaller than 8, you move to the next digit.

Bring down the next digit (9) and combine it with the previous quotient (0). This gives you 09.

Divide 9 by 8. The quotient is 1, and the remainder is 1.

Bring down the next digit (3) and combine it with the remainder (1). This gives you 13.

Divide 13 by 8. The quotient is 1, and the remainder is 5.

Bring down the next digit (6) and combine it with the remainder (5). This gives you 56.

Divide 56 by 8. The quotient is 7, and there is no remainder.

Bring down the next digit (0) and combine it with the quotient (7). This gives you 70.

Divide 70 by 8. The quotient is 8, and there is no remainder.

There are no more digits to bring down, and the division is complete.

The quotient is the result of the division. In this case, 1,493,600 divided by 8 is equal to 186,700.

Therefore, the result of 1,493,600 ÷ 8 is 186,700.

The equation of a line that passes through points (2,5) and (4,3) is

y = -x+7.

Finding the equation of a line:

First, we need to find out the slope for the given points.

(X1,Y1) = (2,5)

(X2,Y2) = (4,3)

formula for slope(m) = \(\frac{Y2 - Y1}{X2 - X1}\)

substitute the points in the above formula

\(\frac{3 - 5}{4 - 2}\) = \(\frac{-2}{2}\)

\(\frac{-2}{2}\) = -1

slope for the given points(m) = -1.

m = -1

The equation of a line is y-y1 = m(x-x1), where x and y are variables.

substituting the values in the above equation then :

y-5 = -1(x-2)

y-5 = -x+2

y+x = 2+5

x+y = 7

y = -x+7

Therefore, the equation of the line passing through the points (2,5) and (4,3) is y = -x+7

1st mechanic (x) worked 5 hours

2nd mechanic (y) worked 15 hours

hope this helps :)

Answer:

The first mechanic worked 5 hours and the second worked 15

Step-by-step explanation:

Let h = hours for first mechanic

j = hours for second mechanic

h+j = 20

75h + 95 j = 1800

Multiply the first equation by -75

-75(h+j = 20)

-75h -75j = -1500

Add this to the second equation to eliminate h

75h + 95 j = 1800

-75h -75j = -1500

----------------------------

0 + 20j = 300

Divide by 20

20j/20 = 300/20

j = 15

Now gind h

h+j = 20

h +15 = 20

h = 5
