Mitch tried to solve an equation step by step.
7.7 = W - 2
7.7 – 2 = W - 2 + 2 Step 1
5.7 = w

Mitch Tried To Solve An Equation Step By Step.7.7 = W - 27.7 2 = W - 2 + 2 Step 15.7 = W

Answers

Answer 1

Answer:

Mitch did not make a mistake

Step-by-step explanation:

The -2 and 2 on the right side cancel out and so you are left with 7.7-2=w. Combine like terms and your left with 5.7=w

Answer 2
Step 1 is done wrong

When simplifying this I would notice that one side is subtracting 2 (a rational number) and that the other also has a rational number.
To simplify this, you have to get rid of the -2 by canceling it out. You can do this by adding 2 on both sides (you have to add 2 to both sides to make sure both sides of the equal sign are equal).

So instead of subtracting 2 on one side and subtracting 2 on the other, you are supposed to add 2 to both sides.
They solved the second step correctly

Hope this helps!

find the 7th term
3, 1,1/3

Answers

The sequence 3, 1,1/3 is a geometric sequence

The 7th term of the sequence is 1/243

How to determine the 7th term?

The sequence is given as:

3, 1,1/3

The above sequence is a geometric sequence with the following parameters:

First term, a= 3Common ratio, r = 1/3

The nth term is then calculated as:

Tn = ar^(n-1)

So, the 7th term is:

T7 = ar^6

Substitute known values

T7 = 3 * (1/3)^6

This gives

T7 = 1/3^5

Evaluate

T7 = 1/243

Hence, the 7th term of the sequence is 1/243

What is the combination?

Each of the different groups or selections can be formed by taking some or all of a number of objects, irrespective of their arrangments is called a combination.

Here we have 4 selections.

Now let's find the number of options for each of these:

First character = 9 options {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}

Second character = 10 options {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10}

Third character = 10 options {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10}

Fourth character = 10 options {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10}

The total number of different combinations is just the product of these 4 numbers:

C = 9×10×10×10 = 9,000

So, we can conclude that the correct option is D.

1. When oil was spilled out in the middle of a lake, it spread out on the surface of the water in a circular pattern. The radius of the circular pattern increased at a rate of 4 feet per minute. ((() = 4tft/min)

A. [3 pts) How fast was the area of the circular pattern increasing per minute? Construct the composite function to show how the area was increasing each minute. ( A() = ft/min). ​

Answers

The rate of change of the area as a function of time is:

A'(t) = 6.28*(R₀ + 4ft/min*t)*(4ft/min)

How to get the rate at which the area increases?

Remember that for a circle of radius R, the area is:

A = 3.14*R^2

Now, if the radius increases at a rate of 4 ft/min, then we can rewrite R as:

R(t) = R₀ + 4ft/min*t

Where t is the time in minutes, and R₀ is the initial radius.

So the area function is:

A(t) = 3.14*(R₀ + 4ft/min*t)^2

The rate of change is given by the differentiation with respect to t, it is:

A'(t) = 2*3.14*(R₀ + 4ft/min*t)*(4ft/min)

A'(t) = 6.28*(R₀ + 4ft/min*t)*(4ft/min)

The rate at which the area increases, as a function of time, is given by:

A'(t) = 6.28*(R₀ + 4ft/min*t)*(4ft/min)

What is an Expression?

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

As it is given that the value of the assets with Patrick is $9,500, while the liabilities are $1,900. Thus, his net worth will be the difference between his assets and his liabilities.

Thus, Patrick's net worth of Patrick can be written as,

[tex]\rm Net\ worth = Assets-Liabilities[/tex]

                [tex]= \$9,500-\$1,900[/tex]

Thus, Patrick's net worth is represented by the expression $9,500-$1,900.

Part D. Explain how you found your answer to Part C.

Answers

The scatter plot that shows the cost of long distance phone call is an illustration of a linear regression

Part A: Draw a line of best fit

See attachment for the line of best fit

Part B: The equation in slope intercept form

From the attached graph, the line passes through the points:

(x,y) = (0,0) and (40,4)

The equation is then calculated using:

y = y2/y1 * x

This gives

y = 4/40 * x

Evaluate

y = 0.1x

Part C: Predict the cost of long distance call of 120 minutes

This means that x = 120

So, we have:

y = 0.1 * 120

y = 12

Hence, the predicted cost of long distance call of 120 minutes is $12

Step-by-step explanation:

See attached image.

Formulate the equation for the line by calculation the slope and adding the y-intercept, as shown.  The y-intercept if the value of y when x = 0.  The equation of a straight line is y=mx+b, where m is the slope and b is the y-intercept.  Note that this b is not the same b in the question (8,b).  The b in the question may be calculated once the equation is found:  y = -3x+6, where -3 is the slope and 6 is the y-intercept (0,6).

Use x = 8 in this equation.  y = -3(8)+6,  y = -18

The point is (8,-18), so b is -18.

ABE is tangent to the circle then m∡OBE = m∡OBD = 90

Then m∡OBD = 90 - 58 = 32

In the triangle DAB :

m∡CAB = m∡DAB = 180 - [m∡BDA + (m∡DBA)]

                                = 180 - [     32       + (90 + 32)]

                                = 180 - [     32       + ( 122) ]
