thank you! ​

Answer:

5a-7b+c

Step-by-step explanation:

Combine and don’t forget to keep the signs

The expression after combing the like terms is 5a - 7b + c.

Like terms in an expression is defined particularly for the expression involving sum of numbers including variables.

Or in other words, the term only differ by a numerical factor. Their coefficients can be added to get the answer.

For example in the expression, 32a + 5a + 3c + a, we can add all the three terms 32a, 5a and a to get 38a.

The given expression is,

6a - 4b - 2a + c - 3b + a

The terms involving 'a' are one like terms, 'b' are another like terms and 'c' are another.

Add together 6a, -2a and a. Also add -4b and -3b. Term including 'c' is only one term.

6a - 4b - 2a + c - 3b + a = (6a - 2a + a) + (-4b - 3b) + c

                                       = 5a - 7b + c

Hence the expression 6a - 4b - 2a + c - 3b + a can be added together by combining like terms to get 5a - 7b + c.

Answer:

See prove of the identity below

Step-by-step explanation:

Recall that the following difference can be factored out as:

[tex](1-tan^4(A)) = (1+tan^2(A)) *(1-tan^2(A))[/tex]

Now we look at the right side of the equal sign, and recall the identity that relates the sine of a double angle 2A with an expression in terms of the tan(A):

[tex]sin(2A) = \frac{2\,tan(A)}{1+tan^2(A)}[/tex]

and similarly, the tangent of the double angle "2A" can be written as:

[tex]tan (2A) = \frac{2*tan(A)}{1-tan^2(A)}[/tex]

We can then combine the two expressions on the right using  the common denominator: [tex](1-tan^4(A)) = (1+tan^2(A)) *(1-tan^2(A))[/tex]:

[tex]tan(2A) +sin(2A)=\frac{2*tan(A)*(1+tan^2(A))}{1-tan^4(A)} +\frac{2*tan(A)*(1-tan^2(A))}{1-tan^4(A)} \\=\frac{2*tan(A)+2*tan(A)}{1-tan^4(A)} =\frac{4*tan(A)}{1-tan^4(A)}[/tex]

And we have proved the identity since the right hand side becomes exactly equal to the left hand side of the equal sign.

One ruler cost 0.60

Step-by-step explanation:

7.50(1) + 1.80(3) + 4x = 20 - 4.70

7.50 + 5.40 + 4x = 15.30

12.90 + 4x = 15.30

4x = 2.40

x = 0.6

Answer:

I'm pretty sure it's 13 units

Step-by-step explanation:

If you go straight from -8 to 5 on a number line or on a graph, it will give you 13 units.

Hope this helps!

Answer: d = 13

The distance between (10,-8) and (10,5) is 13

To find the distance between two points use the Distance Formula:

d = √(x₂ - x₁)² + (y₂ - y₁)²

So d = √(10 - 10)²  +  [5 - (-8)]²   =  13

Page 2:

x = 3

Step-by-step explanation:

Page 1:

A. 3(x - 3) = 10x + 2

3x - 9 = 10x + 2

3x - 9 - 3x = -9

10x + 2 - 2 = 10x

-9 + 2 = -7

10x + 3x = 13x

-7 = 13x

13x / 13 = x

-7 / 13 = -7/13

B. -9x + 3 = -3(3x - 1)

-9x + 3 = -9x + 3

no matter what you'll end up with this

C. 2(3x - 1) = 6x - 1

6x - 2 = 6x - 1

there's no way to solve it :/

Page 2:

2/3x - 3 = 5

2/3x - 3 + 3 = 2/3x

5 - 3 = 2

2/3x = 2

2/3x / 2/3 = x

2 / 2/3 = 3

x = 3

Step-by-step explanation:

The surface area of the cylinder is calculated as  533.8cm²

The surface area of a cylinder can be calculated by adding the areas of its two circular bases and its lateral surface area.

The formula for the surface area of a cylinder is:

Surface Area = 2πr² + 2πrh

where:

Substituting the values into the formula;

S.A = (2*3.14 * 5²) + (2 * 3.14 * 5 * 12)

Answer:

I think it’s step 2 where she distributed the exponents incorrectly but she got it right so since no explanation is really needed then I guess it’s step 2.

step 1 where she divided 5 on both sides. Step 3 is also correct since the answer is 0. so step 2 had the mistake.

Answer:

Explanation:

Let's focus on adding 8/9 to -5/6

To do this, we need the denominators to be the same. The LCD is often the best choice, but you could pick any common denominator.

LCM of 9 and 6 is 18

8/9 = 16/18 after multiplying top and bottom by 2

-5/6 = -15/18 after multiplying top and bottom by 3

So,

8/9 + (-5/6) = 16/18 - 15/18 = 1/18

The two fractions up top combine to 1/18

----------------

The original expression turns into (1/18) over (1/6)

This is the same as

(1/18)*(6/1)

since we flip the second fraction and multiply. Let's simplify that

(1/18)*(6/1)

(1*6)/(18*1)

(6*1)/(6*3)

Given statement solution is :- Runge-Kutta for Differential Equations is y(0.2) = 2.023163 + (0.1923163 + 2 * 0.2064487 + 2 *

To solve the given problems using the fourth-order Runge-Kutta method, we'll follow the general procedure:

Define the differential equation in the form dy/dx = f(x, y).

Choose the step size, h.

Use the fourth-order Runge-Kutta formulas to compute the values of y at each step.

Let's go through each problem and solve them accordingly.

Problem 1:

Find y(0-2) given y' = y - x, y(0) = 2, and h = 0.1.

Here, f(x, y) = y - x.

Using the fourth-order Runge-Kutta method, the formulas are as follows:

k1 = hf(x, y)

k2 = hf(x + h/2, y + k1/2)

k3 = hf(x + h/2, y + k2/2)

k4 = hf(x + h, y + k3)

y(n+1) = y(n) + (k1 + 2k2 + 2k3 + k4)/6

Applying the formulas:

Step 1: For x = 0, y = 2

k1 = 0.1 * f(0, 2) = 0.1 * (2 - 0) = 0.2

k2 = 0.1 * f(0 + 0.1/2, 2 + 0.2/2) = 0.1 * (2.1 - 0.05) = 0.205

k3 = 0.1 * f(0 + 0.1/2, 2 + 0.205/2) = 0.1 * (2.10125 - 0.0525) = 0.20975

k4 = 0.1 * f(0 + 0.1, 2 + 0.20975) = 0.1 * (2.20975 - 0.1) = 0.210975

y(0.1) = 2 + (0.2 + 2 * 0.205 + 2 * 0.20975 + 0.210975)/6 = 2.023163

Step 2: For x = 0.1, y = 2.023163

k1 = 0.1 * f(0.1, 2.023163) = 0.1 * (2.023163 - 0.1) = 0.1923163

k2 = 0.1 * f(0.1 + 0.1/2, 2.023163 + 0.1923163/2) = 0.1 * (2.1177829 - 0.0493416) = 0.2064487

k3 = 0.1 * f(0.1 + 0.1/2, 2.023163 + 0.2064487/2) = 0.1 * (2.1191462 - 0.0509701) = 0.2069196

k4 = 0.1 * f(0.1 + 0.1, 2.023163 + 0.2069196) = 0.1 * (2.2308559 - 0.1) = 0.2130856

Runge-Kutta for Differential Equations is y(0.2) = 2.023163 + (0.1923163 + 2 * 0.2064487 + 2 *

Answer:

[tex]\boxed{\frac{8+x}{2} }[/tex]

Answer:

81π

Step-by-step explanation:

Area of a circle formula is : [tex]A=\pi r^2[/tex]. r stands for radius.

Radius is half of the diameter. To solve for the area of the circle, we must replace r with diameter/2 which is 9 (18/2 = 9).

[tex]A=\pi 9^{2}[/tex]

Now, the question wants us to give the answer in terms of pi. So we are going to simplify the equation WITH PI. Meaning, we aren't going to multiply pi. So we will just simplify 9 squared to 81.

So in terms of pi the area is 81π

Answer:

81π

Step-by-step explanation:

Area of a circle= π[tex]r^{2}[/tex] ( where r is the radius multiplying it twice)

Area of a circle = π × r × r ( this is the formula in simplier terms )

Area of a circle = 3.14 × 9 × 9 ( To get 9 divide 18 by 2 as diameter is 2 radii

Area of a circle = 81π ( multiply the numbers AND THESE ARE THE TWO NINES LEAVING π)

Answer:

The exercise machine's sale price is 560.50$.

To find the answer to your problem, we first have to convert the 5% into a decimal. We do this by simply moving the decimal point to the left two times to make it 0.05.

Then we take 0.05 and multiply it by 590.

0.05 x 590 = 29.5

Now, we subtract 29.5 by the original price:

590 - 29.5 = $560.50
