To use upper and lower sums to approximate the area of the region under the curve y = √6x, we need to divide the interval of integration into a certain number of subintervals of equal width.

Let's say that we want to divide the interval [a, b] into n subintervals of equal width. We can then define the points x0, x1, ..., xn as follows:

x0 = a

x1 = a + (b - a)/n

x2 = a + 2(b - a)/n

...

xn = b

The width of each subinterval is (b - a)/n.

We can then use these points to define the upper sum and lower sum as follows:

Upper sum = ∑ (b - a)/n * max(f(x))

Lower sum = ∑ (b - a)/n * min(f(x))

where the sum is taken over all subintervals, and max(f(x)) and min(f(x)) represent the maximum and minimum values of the function f(x) on each subinterval, respectively.

To calculate the upper and lower sums, we need to evaluate the function f(x) at each of the points x0, x1, ..., xn. For example, if we want to calculate the upper sum using 4 subintervals, we would evaluate the function at the points x0, x1, x2, and x3, and then use these values to calculate the upper sum using the formula above.

Once we have calculated the upper and lower sums, we can use them to approximate the area of the region under the curve. The area of the region is approximately equal to the average of the upper and lower sums.

For example, if the upper sum is 1.5 and the lower sum is 0.5, then the area of the region is approximately (1.5 + 0.5)/2 = 1.

In general, as we increase the number of subintervals, the upper and lower sums will get closer and closer to the actual area of the region, and the approximation will become more accurate.

Answer:

x=8

Step-by-step explanation:

Simplify 2(x+1)−x.

Simplify each term.2x+2−x=10

Subtract x from 2x.x+2=10

Move all terms not containing x to the right side of the equation.

Subtract 2

from both sides of the equation.x1−2

Subtract 2 from x = 10-2

subtract 2 from 10

hope that helps!

Answer:  8

Step-by-step explanation:

First, let's write out the equation:

2(x+1) - x = 10

So, we need to find the value of x.

Let's take an estimate of what x could be.

So, we know it has to be 5-10, because that is over when we add x to one, then multiply by 2.

So, numbers 5-7 couldn't be it, because the value of x is lower than 10. So, we have to guess if it's 8 or 9

Let's use both numbers to solve if it's correct:

2(8+1) - 8 =10

18 - 8 = 10

or

2(9+1) - 8 =10

20 - 8 = 12

So, we have 8 as our answer.

So, x = 8

The probabilities, using the Poisson distribution, are given as follows:

11. A shark attack next year: 0.038.

12. More than one shark attack next year: 0.001.

13. At least one shark attack in the next 100 years: 0.982.

In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following equation:

[tex]P(X = x) = \frac{e^{-\mu}\mu^{x}}{(x)!}[/tex]

The parameters are:

Considering that there have been 8 attacks in 200 years, the mean for n years is given as follows:

[tex]\mu = \frac{8n}{200}[/tex]

Hence the probability of one shark attack in the next year(n = 1, mean = 0.04) is given as follows:

[tex]P(X = 1) = \frac{e^{-0.04}(0.04)^{1}}{(1)!} = 0.038[/tex]

The probability of more than one shark attack is obtained as follows:

P(X > 1) = 1 - P(X ≤ 1)

In which:

P(X ≤ 1) = P(X = 0) + P(X = 1).

Then:

Thus:

P(X > 1) = 1 - (0.961 + 0.038) = 0.001.

For 100 years, the mean is of:

100 x 8/200 = 4.

Thus the probability of at least one attack is of:

P(X > 0) = 1 - e^(-4) = 0.982.

The total hours worked is 40 hours, the total wage for the week is $238, the Total tax is 12.15%, and the paycheck after taxes is $209.44

Taxes are compulsory payments made by a government organization, whether local, regional, or federal, to people or businesses.

Given:

Pay Rate: $5.95 per hour,

Hours Worked: M-8, T-7, W-8, T-9, F-8,

FICA Tax (7.65 %),

State Income Tax (at 3%),

City Income Tax (1.5%),

Calculate the total working hours as shown below,

Total working hours = 8 + 7 + 8 + 9 + 8 = 40 hours

Calculate the total tax,

Total tax = 7.65 + 3 + 1.5 = 12.15%

Calculate total wage,

Total wage =  no of hours × 5.95

Total wage = 40 × 5.95 = $238

Paycheck after-tax deduction = Total wage - 12.15 % of $238

Paycheck after-tax deduction = 238 - 28.56

The cost of the boots is (b) $100

From the question, we have the following parameters that can be used in our computation:

Markup rate = 50%

Markup price of the boot = $150

The cost of the boots can be calculated using the following equation

Markup price of the boot = cost of the boots * (1 + Markup rate)

Substitute the known values in the above equation, so, we have the following representation

150 = cost of the boots  * (1 + 50%)

This gives

150 = cost of the boots  * (1.5)

Divide by 1.5

cost of the boots = $100

In the new graph, the price appears that is increase from 2002 to 2003 is 25% and 100%. Hence, option A is correct.

The Latin phrase "per centum," which means "by the hundred," is where the English word "percentage" comes from.

Percentage segments are those with a numerator of 100. In other words, it is a connection where the whole is always deemed to be valued 100.

As per the data mentioned in the question,

Average cost to rent studio in 2002 = 400 and,

Average cost to rent studio in 2003 = 500

Then percent increase from year 2002 to 2003 will be,

% increase = (500 - 400)/400 × 100

% increase = 25%

The root of a tree is the vertex from which all other vertices can be reached by following edges. The root of a tree is the only vertex that does not have an incoming edge.

In a rooted tree, a vertex is called a leaf if it has no children (i.e., it does not have any edges going out from it). Internal vertices are those that have children and are connected by edges to other vertices in the tree. If a vertex d is the root of a tree, the subgraph with d as its root is defined as the set of vertices that can be reached from d by traversing its edges, as well as the edges connecting them. The root is the only vertex that does not have an incoming edge, and all other vertices can be reached from the root.

Therefore for computing the annual return we simply fund with coupon rate in percentage is 90 dollar

What is a percent simple definition?

A percentage is a portion of a whole expressed as a number between 0 and 100 rather than as a fraction. All of something is 100 percent, half of it is fifty percent, none of something is zero percent. To determine a percentage, you divide the portion of the whole by the whole itself and multiply by 100.

The additional sum of money over the principal sum of deposit or loan is called compound interest.

The yearly return on $ 3 ,000 investment will be $90.

This can be estimated as:

Investment = $3,000

Coupon rate in percentage = 3%

The computation of yearly return can be estimated as:

the flux of curI(F) through the surface area in the figure as with integral:

flux of curl(F) = x^2 + 4yz(2) + 2∫x√(y^2 + 1) dy - 32z + 2y^2z

First, we calculate the curl of F: curI(F) = (2z, -2x, 2y).

Next, we apply Stokes' Theorem to calculate the flux of curI(F) through the surface in the figure. We start by computing the line integral of F around the boundary of the surface. This is given by:

flux of curl(F) = 2 ∫ (x + 2yz) dx + 2 ∫ (x√(y^2 + 1))dy - 2 ∫ (16 - 2yz)dz

We can now evaluate this line integral by splitting it into a sum of integrals:

flux of curl(F) = 2 ∫ (x + 2yz) dx + 2 ∫ (x√(y^2 + 1))dy - 2 ∫ (16 - 2yz)dz

= 2∫x dx + 4∫yz dx + 2∫x√(y^2 + 1) dy - 32∫dz + 4∫yz dz

= 2x^2/2 + 4∫yz dx + 2∫x√(y^2 + 1) dy - 32z + 4yz^2/2

= x^2 + 4yz∫dx + 2∫x√(y^2 + 1) dy - 32z + 2y^2z

Finally, we can evaluate the flux of curI(F) through the surface in the figure as:
