The estimate of ∫e^x dx using rectangles with heights given by right-hand endpoints and four subintervals (n = 4) can be determined by evaluating the function at those endpoints and multiplying by the width of each rectangle.

Among the given options, the correct representation of the estimate is:

∫e^x dx is approximately (0.5)e^0.5 + (0.5)e^1 + (0.5)e^1.5 + (0.5)e^2.

This is because we divide the interval [0,2] into four subintervals of equal width, each with a width of 0.5. For the right-hand endpoint approximation, we evaluate the function e^x at those endpoints.

The height of each rectangle is given by e^x evaluated at the right-hand endpoint of each subinterval. The width of each rectangle is 0.5.

By multiplying the height and width of each rectangle and summing them up, we obtain the estimate of the integral.

Therefore, the correct representation is (0.5)e^0.5 + (0.5)e^1 + (0.5)e^1.5 + (0.5)e^2 as an estimate of ∫e^x dx using rectangles with right-hand endpoints and four subintervals.

Answer:

Step-by-step explanation:

So in your account you got $175.29

Then you deposit mean increase the amount of money in your account by $48.75

So: 175.29+48.75 = 224.04

The price is $249.99

So: 249.99 - 224.04 = $25.95

You need to save $25.95 in order to buy your cell phone

To buy the cellphone of worth $249.99, additional $25.95 are required.

Calculate the answer using a math operator is referred to as a mathematical operation.

Basic mathematical operations are addition, multiplication, subtraction and division.

Given that,

The price of cellphone = $249.99

The amount in saving account = $175.29

Additional amount deposit in account = $48.75

Total amount in account after deposit = 175.29 + 48.75 = 224.04

Since, the price of cellphone is $249.99

And the amount in account = 224.04

So the more amount required = 249.99 - 224.04 = 25.95

To buy the cell phone $25.95 are required.

Answer:

The answer is (6.5,3)

Step-by-step explanation:

The solution is in the image

The endpoints of GH are G(10,1) and H(3,5), then, the midpoint of GH is M(6.5, 3).

Here, we have to find the midpoint of line segment GH, we can use the midpoint formula.

The midpoint formula states that the coordinates of the midpoint (M) of a line segment with endpoints (x₁, y₁) and (x₂, y₂) are given by:

M(x, y) = \(((x_1 + x_2) / 2, (y_1 + y_2) / 2)\)

Then the midpoint will be

x = (x₁ + x₂) / 2

y = (y₁ + y₂) / 2

In this case, the endpoints of GH are G(10, 1) and H(3, 5).

Let's use the midpoint formula to find the midpoint (M) of GH:

x-coordinate of M = (x-coordinate of G + x-coordinate of H) / 2

x-coordinate of M = (10 + 3) / 2

x-coordinate of M = 13 / 2

x-coordinate of M = 6.5

y-coordinate of M = (y-coordinate of G + y-coordinate of H) / 2

y-coordinate of M = (1 + 5) / 2

y-coordinate of M = 6 / 2

y-coordinate of M = 3

So, the midpoint of GH is M(6.5, 3).

Answer:

x = 1/2 and y = 3

Step-by-step explanation:

Let

4x + 5y = 17       ......(i)

2x + 4y = 13       .....(ii)

Multiply equation (ii) by 2 to make like 'x' terms. Thus, the new equations are:

4x + 5y = 17       ......(i)

4x + 8y = 26       .....(ii)

Subtract equation (i) from (ii)

4x + 8y - (4x + 5y) = 26 - 17

4x + 8y - 4x - 5y = 9

3y = 9

y = 3

To find x, substitute value of y into any equation

4x + 5y = 17

4x + 5*3 = 17

4x + 15 = 17

4x = 17 - 15

4x = 2

x = 2/4

The function f(x) = x^4 + bx^2 + 1 has an inflection point at x = 0,

What is the inflection point?

An inflection point of a function is a point on the graph of the function where the concavity (curvature) of the graph changes. In other words, an inflection point is a point where the curve switches from being concave up to concave down, or vice versa.

The function f(x) = x^4 + bx^2 + 1 has an inflection point at x = 0, because the concavity of the graph changes at that point. To find the value of b such that the function has at least one inflection point over the interval (1,2), we can set x = 1 and x = 2 in the function and solve for b.

If we set x = 1, we get the equation f(1) = 1 + b + 1 = 0. Solving for b, we find that b = -2.

If we set x = 2, we get the equation f(2) = 16 + 2b + 1 = 0. Solving for b, we find that b = -9.

Since the function has an inflection point at x = 0 for any value of b, it will have at least one inflection point over the interval (1,2) for any value of b.

Therefore, the value of b can be any real number.

Step-by-step explanation:

In the case where the particular car Roy wants, enterprise charges an amount of $185 per week with additional 25 cents per mile driven and Avis charges a flat fee of $275 per week, the number of miles driven where renting from enterprise be the less expensive option is less than 3.6 miles.

In the case of enterprise, the cost can be expressed in terms of miles driven, say x as 185 + 25x. In order for the renting from enterprise option to be less expensive than Avis

185 + 25x < 275    

25x < 275 - 185

x < 90/25

x < 3.6 miles

Factor.

The answers are -1/3, -8/3

Answer:

1 mile/hour is equivalent to 1.47 feet/seconds

Step-by-step explanation:

Given

\(88 ft/s= 60 miles/hr\)

Required

Determine the equivalent of 1 mile/hour

\(88\ ft/s= 60\ miles/hr\)

Express 60 as 60 * 1

\(88\ ft/s= 60 * 1\ mile/hr\)

Divide both sides by 60

\(\frac{88\ ft/s}{60}= \frac{60 * 1\ mile/hr}{60}\)

\(\frac{88\ ft/s}{60}= 1\ mile/hr\)

Reorder

\(1\ mile/hr = \frac{88\ ft/s}{60}\)

Divide 88 by 60

\(1\ mile/hr = 1.46666666667\ ft/s\)

Approximate to 3 significant figures

\(1\ mile/hr = 1.47\ ft/s\)

Hence;

1 mile/hour is equivalent to 1.47 feet/seconds

The hydrostatic force on the window is approximately 47,481 Newtons.

We can use the formula for hydrostatic force, which is:

F = ρghA

where F is the hydrostatic force, ρ is the density of the fluid (water in this case), g is the acceleration due to gravity, h is the depth of the window, and A is the area of the window.

First, we need to find the area of the window. Since the window is a semi-circle with diameter 70 centimeters, the radius is 35 centimeters, and the area is:

A = (π/2)r^2

= (π/2)(35 cm)^2

= 1225π/2 cm^2

Next, we need to convert the depth of the window to meters:

h = 2.5 m

We also need the density of water, which is approximately:

ρ = 1000 kg/m^3

Finally, we need the acceleration due to gravity, which we can assume is:

g = 9.8 m/s^2

Now we can plug these values into the formula:

F = ρghA

= (1000 kg/m^3)(9.8 m/s^2)(2.5 m)(1225π/2 cm^2)

≈ 47,481 N

Therefore, the hydrostatic force on the window is approximately 47,481 Newtons.

Answer:

\( \frac{x}{4} + \frac{1}{2} = \frac{1}{8} \)

\( \frac{x}{4} = - \frac{3}{8} \)

\(x = - \frac{3}{2} = - 1 \frac{1}{2} \)

The solution to the equation x/4 + 1/2 = 1/8 is x = -3/2.

Consider the equation, we have only one x term, so taking all the terms without x to the other side and terms with x on one side.

x/4 + 1/2 = 1/8

Take the 1/2 term on the other side,

x/4=1/8 - 1/2

Taking the LCM on the Right side,

x/4 = (1-4) / 8

x/4 = -3/8

Now, we have x/4 so what we can do is, shift the 4 to the other side too, we get,

x = ( -3/8) * 4

x = -3/2

The solution to the equation x/4 + 1/2 = 1/8 is x = -3/2.

Step-by-step explanation:

To solve this problem, you can use the pythagorean theorem, which is a^2 + b^2 = c^2 where a and b are legs and c is the hypotenuse. We can plug in the values of 15 and 20, and solve for c:

15^2 + 20^2 = c^2

225 + 400 = c^2

625 = c^2

c = 25

This means the hypotenuse is 25.

First, we want to note two things:

We can describe this with an inequality:  x ≥ -10
Be sure you use ≥ and not >, since -10 is included.

We can describe this with interval notation: [ -10, infty )
Be sure you use [ and not ( on -10, since -10 is included.
