Answer:

a= −b/x

Step-by-step explanation:

Let's solve for a.

ax2+bx=0

Step 1: Add -bx to both sides.

ax2+bx+−bx=0+−bx

ax2=−bx

Step 2: Divide both sides by x^2.

ax2x2=−bxx2

a=−bx

Answer:

Step-by-step explanation:

perfect sqaure formula (u+w)²=u²+2uw+w²

ax²+bx+c=0  divide by a

\(x^{2} +\frac{bx}{a} + \frac{c}{a} =0\)  so u=1, 2uw=2*1*w= b/a, so w=b/2a

\((x^{2}+ \frac{bx}{a} +\frac{b^{2} }{4a^{2} } ) +\frac{c}{a} -\frac{b^{2} }{4a^{2} }=0\) now that we formed the perfect sqare solve

\((x +\frac{b}{2a} )^{2} +\frac{c*4*a-b^{2} }{4a^{2} } =0\) but we can factor a negative in front of the fraction

\((x+\frac{b}{2a} )^{2} -\frac{b^{2} -4ac }{4a^{2} } =0\) now isolate the 2 terms and squareroot both sides

\(\sqrt{ (x +\frac{b}{2a} )^{2}} =\sqrt{ \frac{b^{2} -4ac }{4a^{2} } }\) and you will be left with

\(x +\frac{b}{2a} =\ + - \frac {\sqrt{ b^{2} -4ac} }{2a }\)  subtract b/2a from both sides

x= \(\frac{-b+ - \sqrt{b^{2}-4ac } }{2a}\)

Using line tangent, the approximation for f(2.1) is 3.95

Given,

The point (a, f(a)) is on the line tangent to the graph of y = f(x) at x = a, which has a slope of f'(a).

The equation be like;

y - f(a) / (x - a) = f'(a)

y = f'(a) (x - a) + f(a)

Using the provided data and a = 2, we can determine that the tangent line to the graph of y = f(x) at x = 2 has equation

y = f'(2) (x - 2) + f(2)

y = -1/2 (x - 2) + 4

To compute a "approximation of f(2.1) using the line tangent to the graph of f at x = 2," one must substitute x = 2.1 for f in the equation for the tangent line (2.1). You get 2.1 when you plug this in.

y = -1/2 (x - 2) + 4

y = -1/2 (2.1 - 2) + 4

y = -1/2 x 0.1 + 4

y = 3.95

That is,

The interval in which the velocity is zero in the graph is from 3.0 to 4.0 hours. Therefore, the correct option is C, "3.0 to

4.0 hours."

The velocity of the object is zero if the position of the object does not change with time. If the position of the object

marked on the position-time graph is the same forming a straight line on a graph between a time interval, then the

velocity of the object during that time interval is zero.

The object has zero velocity when it does not displace with time. The velocity of the object is zero when there is no

displacement of the object. The position of the object between two different time intervals remains the same. The

velocity is given by the relation v= (Δx/Δt)= (x 2 -x 1 )/ (t 2 -t 1)

From the graph provided, we see that the velocity is zero in the interval from 3.0 to 4.0 hours.

At this time, the velocity of the object is not changing, hence, it is zero.

Therefore, the correct option is C, "3.0 to 4.0 hours."

There are 120 ways that the store manager can display 5 different brands of toothpaste in a row.

A store manager wants to display 5 different brands of toothpaste in a row.

The Number of ways the manager can do this is given by the permutation formula.

The  formula is used when there is a need to determine the number of ways to select or arrange objects, taken some at a time, without repetition. This is given by;

\(^nP_r = n!/(n-r)!\)

Here, n is the total number of objects to choose from and r is the number of objects taken at a time.

Applying the formula to this problem, we get,

n = 5 (because the manager wants to display 5 different brands of toothpaste in a row),

and r = 5 (because there are 5 brands to choose from).

Therefore,

\(^5P_5 = 5!/(5-5)!^5P_5\\

= 5!/0!^5P_5 \\

= 5*4*3*2*1/1  ^5P_5 = 120\)

Therefore, there are 120 ways that the store manager can display 5 different brands of toothpaste in a row.

Answer:

Ok, sure.

Step-by-step explanation:

Let's denote the cost of a parking ticket as "P" and the cost of a traffic violation as "T".

From the information provided, we can create the following equations:

Equation 1: 3P + 14T = 2030 (for the first month)

Equation 2: 11P + 11T = 2200 (for the second month)

We now have a system of equations to solve. We can use various methods to find the values of P and T.

One common method is to use substitution. We can solve Equation 1 for P and substitute it into Equation 2:

From Equation 1, we can isolate P:

3P = 2030 - 14T

P = (2030 - 14T) / 3

Substituting P into Equation 2:

11((2030 - 14T) / 3) + 11T = 2200

Now, we can solve this equation to find the value of T.

11(2030 - 14T) + 33T = 6600

22330 - 154T + 33T = 6600

22330 - 121T = 6600

-121T = 6600 - 22330

-121T = -15730

T = -15730 / -121

T ≈ 130

Now that we have the value of T, we can substitute it back into Equation 1 to find the value of P:

3P + 14(130) = 2030

3P + 1820 = 2030

3P = 2030 - 1820

3P = 210

P = 210 / 3

P = 70

Therefore, each parking ticket costs $70, and each traffic violation costs $130.

Answer:

To calculate the cost of parking tickets and traffic violations, you need to know the number of tickets and the total amount of fines. Then you can divide the total amount by the number of tickets to get the cost per ticket.

For example, in the first month, the suspect had 3 parking tickets and 14 traffic violations totaling $2030. The total number of tickets is 3 + 14 = 17. The cost per ticket is $2030 / 17 = $119.41.

In the second month, the suspect had 11 parking tickets and 11 traffic violations totaling $2200. The total number of tickets is 11 + 11 = 22. The cost per ticket is $2200 / 22 = $100.

Therefore, each parking ticket costs $119.41 in the first month and $100 in the second month. Each traffic violation costs $119.41 / 14 = $8.53 in the first month and $100 / 11 = $9.09 in the second month.

The measure of angle B is approximately 42°.

Use the given ratios to determine the measure of the variable in each problem.

Round angles to the nearest degree and lengths to the nearest tenth.

A = 50°, b = 12, c = 14

We can use the law of cosines to find angle B.

The law of cosines states that c² = a² + b² - 2abcos(C),

where C is the angle opposite side c.

We can rearrange this formula to find cos(C):

cos(C) = (a² + b² - c²) / 2ab

Now, we can substitute the given values and solve for cos(C):

cos(B) = (12² + 14² - 20²) / (2 × 12 × 14)

cos(B) = 0.7436

Now, we can use the inverse cosine function to find angle B:

B = cos⁻¹(0.7436)B = 41.6°

Therefore, the measure of angle B is approximately 42°.

Step-by-step explanation:

The work done pulling the bucket to the top of the well is 104,299.4 pound-force-feet (lb*ft).

To find the work done pulling the bucket to the top of the well, we need to consider the weight of the bucket, the weight of the water, and the work done against gravity.

First, let's calculate the weight of the bucket and water combined. The weight of the bucket is 4 pounds, and the weight of the water is 35 pounds. Therefore, the total weight is 4 + 35 = 39 pounds.

Next, let's calculate the distance the bucket is pulled up. The well is 83 feet deep, so the bucket is pulled up a distance of 83 feet.

Now, let's calculate the work done against gravity. Work is calculated by multiplying the force applied by the distance over which the force is applied. In this case, the force is equal to the weight of the bucket and water, which is 39 pounds. The distance is 83 feet.

Work = Force * Distance
Work = 39 pounds * 83 feet

To calculate the work, we need to convert the weight from pounds to a unit called pound-force (lbf). 1 pound force is equal to the force exerted by a mass of 1 pound under acceleration due to gravity.

To convert from pounds to pound-force, we need to multiply by the acceleration due to gravity. The acceleration due to gravity is approximately 32.2 feet per second squared.

39 pounds * 32.2 feet per second squared = 1255.8 pound-force

Finally, we can calculate the work done pulling the bucket to the top of the well.

Work = 1255.8 pound-force * 83 feet
Work = 104,299.4 pound-force-feet (or lb*ft)

the CLT holds for a random sample of 65 non-farm workers, which allows us to make statistical inferences about the proportion of government employees among non-farm workers using the normal distribution.

Yes, the Central Limit Theorem (CLT) holds for this scenario. The CLT states that, regardless of the underlying distribution of a population, as long as the sample size is sufficiently large (usually considered to be at least 30), the distribution of sample means will be approximately normal. In this case, we have a random sample of 65 non-farm workers, which is large enough to satisfy the conditions of the CLT.

The CLT is important because it allows us to make inferences about population parameters (such as the proportion of government employees among non-farm workers) based on sample statistics (such as the proportion of government employees in our sample). Specifically, we can use the normal distribution to calculate confidence intervals and perform hypothesis tests, which can help us determine whether our sample is representative of the population and draw conclusions about the population parameter of interest.

Answer: The two factors are x+7 and x+2

The polynomial factors to (x+7)(x+2)

=========================================================

Explanation:

In the upper left corner we have x^2. We get this by multiplying x with x

So,

x*x = x^2

This means you'll have x to the left of x^2, and another copy of x above the x^2. These new terms are outside the box.

Now ask yourself, what goes in the blank x times ___ = 7x. The answer must be "7" since x times 7 = 7x. So we'll write 7 above the 7x, outside the box. Up top, the x and 7 help form the factor (x+7)

Along the left side, the other factor is (x+2) for similar reasoning. Notice how we effectively have x times ___ = 2x and '2' must go in the blank. So a '2' must go to the left of the 2x.

Putting everything together, the two factors are (x+7) and (x+2).

Therefore, x^2+7x+2x+14 fully factors to (x+7)(x+2)

This is the same as saying x^2+9x+14 factors to (x+7)(x+2)
