Answer:

x=8

Step-by-step explanation:

Follow the order of operations to simplify the equation:

5(x-3) +2x=41  

Start by multiplying into the parenthesis: 5x-15+2x=41

Combine like terms: 5x+2x-15=41 then simplify: 7x-15=41

Add 15 to both sides: 7x=56

Divide both sides by 7 to get x by itself: x=8

Step-by-step explanation:

CONCEPT:

- One solution is when the final variable would be able to find a solution.

- Infinite solution is when the equations result in 0=0, meaning any number will fit

- No solution is when the equation results in both sides on equal.

SOLVE:

Given

3/4x-7=3(1/6x+1)

Expand Parenthesis

3/4x-7=1/2+3

Multiply both sides by the LCM of fractions (Least Common Multiple)

4(3/4x-7)=4(1/2x+3)

3x-28=2x+12

Subtract both sides by 2x

3x-28-2x=2x+12-2x

x-28=12

Add both sides by 28

x-28+28=12+28

x=40

Since we are able to get exactly one solution, there is only one solution.

The measure of side length EF in the right triangle is 24.

The Pythagorean theorem states that the "square on the hypotenuse of a right-angled triangle is equal in area to the sum of the squares on the other two sides.

It is expressed as;

c²  = a² + b²

From the diagram:

Hypotenuse DE = c = 26

Leg DF = a = 10

Leg EF = b = ?

Plug in the values and solve for b:

c²  = a² + b²

26²  = 10² + b²

676  = 100 + b²

b² = 676  - 100

b² = 576

b = +√576 ( we take the positive value since we are dealing with dimensions)

b = 24

Therefore, the length EF is 24.

Option C)24 is the correct answer.

Answer:

Option A

Step-by-step explanation:

Option A is an arithmetic sequence.

Each week, the salary goes up by a fixed $50.

To verify this, subtract any two consecutive weeks' salaries.

For example: $250 - $200 = $50; $350 - $300 = $50, etc.

The common difference in 50.

We have an arithmetic sequence with 20 terms. The first term is $200. We need to find the sum of the 20 terms.

The sum of an arithmetic sequence is given by the formula:

\( S_n = \dfrac{n}{2} \times [2a_1 + (n - 1)d] \)

S_n = sum of first n terms

n = number of terms = 20

a_1 = first term = 200

d = common difference = 50

\( S_{20} = \dfrac{20}{2} \times [2(200) + (20 - 1)(50)] \)

\( S_{20} = 10 \times [400 + 19(50)] \)

\( S_{20} = 10 \times [400 + 19(50)] \)

\( S_{20} = 13500 \)

Option A gives a total of $13,500 for the first 20 weeks.

Option B is a geometric sequence in which the salary goes up by 10% each week. To verify this, divide any salary by the previous week's salary.

For example: $220/$200 = 1.10; $266.20/$242 = 1.10; in each case, each salary is 1.1 times the previous week's salary which means a 10% increase. The common ratio of the geometric sequence is 1.1.

We need the formula for the sum of the first n terms of a geometric sequence.

\( S_n = \dfrac{a_1(1 - r^n)}{1 - r} \)

\( S_{20} = \dfrac{200(1 - 1.1^{20})}{1 - 1.1} \)

\( S_{20} = \dfrac{200(1 - 6.7274999)}{-0.1} \)

\( S_{20} = 11455 \)

Option B gives a total of $11,455 for the first 20 weeks.

Answer: Option A

The Binomial probability of x = 3 for the given parameters is 0.2048

The Binomial probability relation can expressed as :

\(P(x) = nCx * p^{n} * q^{n-x}\)

where :

for x = 3

We substitute x into the equation thus :

P(x = 3) = 17C3 * (1/8)³ * (1 - 1/8)¹⁴

P(x = 3) = 0.2048

Therefore, the probability of x = 3 in the scenario given is 0.2048

The distance between the two points is

d = √( -2-x)² + (3 -y)² OR d = √ (x+2)² + (y-3)².

Distance between two points is the length of the line segment that connects the two points in a plane.

The distance between two points is expressed as;

d = √ (X-x )² + (Y-y)²

X = -2

x = x

Y = 3

y = y

Therefore the distance between the two points is

d = √( -2-x)² + (3 -y)²

or it can also be written in this form

d = √ x-(-2)² + (y-3)²

d = √ x+2)² + (y-3)²

therefore the model of the distance between the two points can be

d = √( -2-x)² + (3 -y)² OR d = √ (x+2)² + (y-3)².

  \(\begin{array}{|r|c|c|c|c|c|c|c|}\cline{1-8}\text{Steps}&1&2&3&4&5&6&7\\\cline{1-8}\text{Rods}&4&10&18&28&40&54&70\\\cline{1-8}\end{array}\)

Step-by-step explanation:

Given a diagram of staircase frames with 1, 2, and 3 steps, along with a table showing the number of rods in each frame, you are asked to fill in the table for up to 7 steps.

Looking at the attached diagram, we see the number of blue rods is equal to the number of red rods, and each of those numbers is 1 more than the number of steps in the frame. These are the added rods from the previous frame.

Starting with 0 steps, we have 0 rods. (This is not shown in the table.)

Step 1 adds 2×(1+1) = 4 rods for a total of 4 in a 1-step frame.

Step 2 adds 2×(2+1) = 6 rods, for a total of 4+6 = 10 in a 2-step frame.

Step 3 adds 2×(3+1) = 8 rods, for a total of 10+8 = 18 in a 3-step frame.

Step 4 adds 2×(4+1) = 10 rods, for a total of 18+10 = 28 in a 4-step frame.

Each addition is 2 more than the previous addition, so the next few table entries are ...

  28 +12 = 40 (for 5 steps)

  40 +14 = 54 (for 6 steps)

  54 +16 = 70 (for 7 steps)

Then the table is ...

  \(\begin{array}{|r|c|c|c|c|c|c|c|}\cline{1-8}\text{Steps}&1&2&3&4&5&6&7\\\cline{1-8}\text{Rods}&4&10&18&28&40&54&70\\\cline{1-8}\end{array}\)

A graph of the table values is shown in the second attachment. In the above, we have described a recursive relation between the steps (n) and rods (r).

In the second attachment, we show that relation can also be described by the explicit rule ...

__

Additional comment

The first differences of the numbers of rods are ...

  10 -4 = 6

  18 -10 = 8

Then the second difference is ...

  8 -6 = 2

As we noted above, the second difference is a constant, meaning succeeding first differences are 10, 12, 14, 16, ... as we have shown.

The constant 2nd difference means the relation can be described by a 2nd degree polynomial. The leading coefficient of that polynomial is half the value of the 2nd difference: 2/2 = 1.

Knowing that the sequence is described by ...

  r(n) = 1·n² +bn +c

we can find values of 'b' and 'c' to fill out the equation. Using the first two table entries, we have ...

  r(1) = 4 = 1² +1b +c

  r(2) = 10 = 2² +2b +c

Subtracting the first equation from the second gives ...

  (10) -(4) = (4 +2b +c) -(1 +b +c)

  6 = 3 +b   ⇒   b = 3

Using the first equation to find c, we have ...

  4 = 1 + b + c = 1 + 3 + c   ⇒   c = 0

This means our explicit equation is ...

  r(n) = n² +3n . . . . as we have seen in the graph

Final speed after slowing down by 15 miles per hour and reducing the speed by one third is 25 miles per hour.

Let's break down the steps to determine the final speed:

Step 1: Convert the speed from miles per minute to miles per hour.

Since you're driving one and a half miles per minute, we need to convert it to miles per hour. There are 60 minutes in an hour, so we multiply 1.5 by 60 to get 90 miles per hour.

Step 2: Slow down by 15 miles per hour.

Subtract 15 from the initial speed of 90 miles per hour, resulting in 75 miles per hour.

Step 3: Reduce the speed by one third.

To find one third of 75 miles per hour, we divide it by 3, which gives us 25 miles per hour.

Therefore, the final speed after slowing down by 15 miles per hour and reducing the speed by one third is 25 miles per hour.

Because he has to store it all and not all would fit in the third container.

The derivatives for this problem are given as follows:

a) \(f^{\prime}(x) = -4\sin{x} + \frac{1}{x + 1}\)

b) \(f^{\prime}(x) = \sec{x}\tan^{2}{x} + \sec^3{x}\).

The derivative of the sum is the sum of the derivatives.

In this problem, the function is:

\(f(x) = 4\cos{x} + \ln{(x + 1)}\)

Using a derivative table for the derivatives of the cosine and the ln, the derivative of the function is:

\(f^{\prime}(x) = (4\cos{x})^{\prime} + (\ln{(x + 1)})^{\prime}\)

\(f^{\prime}(x) = -4\sin{x} + \frac{1}{x + 1}\)

What is the product rule?

The derivative of the product is given as follows:

\((f(x) \times g(x))^{\prime} = f^{\prime}(x)g(x) + g^{\prime}(x)f(x)\)
