-2/3-(-3/5)+2/3-1/2 rational numbers solve

Answer:

5x^3+15x^2-35x

Step-by-step explanation:

Firstly, you want to combine the "x"s in the (5x*x^2) and the (5x*3x). Once you have that (you will get 5x^3 and 15x^2), you can move onto the last set of parenthesis. We can get 35x from here. Finally, the last step is to add the correct signs. Our final answer will then be 5x^3+15x^2-35x. I hope this helped and please don't hesitate to reach out with more questions!

The compound interest for the given investment is approximately $15,043.98, rounded to the nearest cent.

To find the compound interest for an investment of $43,000 for 5 years at 6% compounded continuously, we use the formula:

A = P * e^(rt)

Where A is the future value, P is the principal amount ($43,000), e is the base of the natural logarithm (approximately 2.718), r is the annual interest rate (0.06), and t is the time in years (5).

A = 43,000 * e^(0.06 * 5)
A ≈ 43,000 * e^(0.3)
A ≈ 43,000 * 1.34986
A ≈ 58,043.98

Now, to find the compound interest, subtract the principal from the future value:

Interest = A - P
Interest = 58,043.98 - 43,000
Interest ≈ 15,043.98

Answer:

Step-by-step explanation:

2x2+5x−10=x2+4

Step 1: Subtract x^2+4 from both sides.

2x2+5x−10−(x2+4)=x2+4−(x2+4)

x2+5x−14=0

For this equation: a=1, b=5, c=-14

x=2 or x=−7

Answer:

x=2 or x=−7

Answer:

x = 2 or x= -7

Step-by-step explanation:

We can use factorisation to solve this.

First, we shift all the variables to one side (see attachement)

Then, we need to find the value of x, which multiples to give -14 and adds together to give 5.

7 - 2 = 5

and 7 x (-2) = -14.

Now we factorize (group into brackets) to find the values of x.

We solve for x to find the final answer.

Yes, it is possible to prove that two triangles are congruent by using the AAS congruence theorem.

The AAS congruence theorem states that if two angles and the included side of one triangle are congruent to two angles and the included side of a second triangle, then the two triangles are congruent. This theorem can be used to prove that two triangles are congruent if two of the angles in the triangle and the side between them are congruent to two angles and the side between them of the other triangle. To prove congruence using the AAS congruence theorem, it is important to use the right angle and side measurements to ensure that the two triangles are congruent. If the measurements are correct, then the two triangles will be congruent.

The surface area of the part of the plane \(z = 2 + 7x + 3y\) that lies inside the cylinder \(x^2 + y^2 = 4\) is \(\sqrt{59}\pi\).

To find the surface area of the part of the plane \(z = 2 + 7x + 3y\) that lies inside the cylinder \(x^2 + y^2 = 4\), we can set up a double integral over the region of the plane that lies within the cylinder.

First, let's find the bounds of integration for the double integral. Since the cylinder is defined by \(x^2 + y^2 = 4\), we can express \(y\) as a function of \(x\) or \(x\) as a function of \(y\). Let's solve for \(y\) in terms of \(x\):

\[y = \pm\sqrt{4 - x^2}\]

To find the bounds for \(x\), we need to determine the range of \(x\) values that satisfy the cylinder equation. Since the cylinder is centered at the origin and has a radius of 2, the bounds for \(x\) are \([-2, 2]\).

Now, we can set up the double integral to calculate the surface area:

\[S = \iint_D \sqrt{1 + \left(\frac{\partial z}{\partial x}\right)^2 + \left(\frac{\partial z}{\partial y}\right)^2} \, dA\]

Where \(D\) is the region of the plane that lies within the cylinder.

Using the given plane equation \(z = 2 + 7x + 3y\), we can find the partial derivatives:

\(\frac{\partial z}{\partial x} = 7\) and \(\frac{\partial z}{\partial y} = 3\)

Substituting these values into the surface area integral, we have:

\[S = \int_{-2}^{2} \int_{-\sqrt{4 - x^2}}^{\sqrt{4 - x^2}} \sqrt{1 + 7^2 + 3^2} \, dy \, dx\]

\[S = \int_{-2}^{2} \int_{-\sqrt{4 - x^2}}^{\sqrt{4 - x^2}} \sqrt{59} \, dy \, dx\]

\[S = \sqrt{59} \int_{-2}^{2} 2\sqrt{4 - x^2} \, dx\]

To evaluate this integral, we can make a substitution \(x = 2\sin \theta\):

\[S = \sqrt{59} \int_{-\frac{\pi}{2}}^{\frac{\pi}{2}} 2\sqrt{4 - 4\sin^2 \theta} \cos \theta \, d\theta\]

\[S = \sqrt{59} \int_{-\frac{\pi}{2}}^{\frac{\pi}{2}} 4\cos^2 \theta \, d\theta\]

\[S = \sqrt{59} \int_{-\frac{\pi}{2}}^{\frac{\pi}{2}} 2(1 + \cos 2\theta) \, d\theta\]

\[S = \sqrt{59} \left[2\theta + \frac{1}{2}\sin 2\theta\right]_{-\frac{\pi}{2}}^{\frac{\pi}{2}}\]

\[S = \sqrt{59} \pi\]

Therefore, the surface area of the part of the plane that lies inside the cylinder is \(\sqrt{59}\pi\).

There are nC2 different votes possible, where n is the number of bands on the list and nC2 represents the number of ways to choose 2 bands out of n.

To calculate nC2, we can use the formula for combinations, which is given by n! / (2! * (n-2)!), where ! represents factorial.

Let's say there are m bands on the list. The number of ways to choose 2 bands out of m can be calculated as m! / (2! * (m-2)!). Simplifying this expression further, we get m * (m-1) / 2.

Therefore, the number of different votes possible is m * (m-1) / 2.

In the given scenario, we don't have the specific number of bands on the list, so we cannot provide an exact number of different votes. However, you can calculate it by substituting the appropriate value of m into the formula m * (m-1) / 2.

Step-by-step explanation:

A car travel 20kph faster than a truck. the car cover 350 km in two hours less than the time. The speed of the car is 50 km/h. The speed of truck is 70 km/h.

You can determine an object's speed if you know how far it moves in a given amount of time. For instance, an automobile is moving at a pace of 70 miles per hour if it covers 70 miles in an hour (miles per hour).

Given,

A car travel 20kph faster than a truck. the car cover 350 km in two hours less than the time.

Let s represent the truck's speed and (s+20) represent the car's speed.

to determine each vehicle's time

Time = Speed / Distance

truck time = 350/s

Time in an automobile is 350/(s+20)

Truck time - car time = 2 hours

So,

(350/s) - [350/(s+20)] = 2

LCM is s(s+20)

[350(s+20) - 350s]/s(s+20) = 2

Cross multiplying,

350(s+20) - 350s = 2s(s+20)

Simplifying the equation,

350s + 7000 - 350s = 2s² + 40s

Now, we have quadratic equation to simplify,

2s² + 40s - 7000 = 0

Dividing the equation by 2

s² + 20s - 3500 = 0

Factorizing,

s= 50

s= -70 (impossible because of the sign)

Hence the truck's speed is s = 50 km/h.

The speed of the car is s + 20 = 70 km/h.

Answer:

268 increased by 75% of its value = 469

Step-by-step explanation:

hope this helps :))

The number when 268 is increased by 75%​ will be 469.

The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates for one hundred percent. It is symbolized by the character '%'.

The percentage is given as,

Percentage (P) = [Final value - Initial value] / Initial value x 100

Let 'n' be the increased number. Then the equation is given as,

75% = [(n - 268) / 268] x 100

Simplify the equation, then we have

0.75 = (n - 268) / 268

n - 268 = 201

n = 201 + 268

n = 469

The number when 268 is increased by 75%​ will be 469.
