let f(x)=2x+3 and g(x)=x×x-1
find a. f(g(x)) b.g(f(x))

Answer:

3ab(c+2a)

Step-by-step explanation:

Given data

3abc+6a²b

we can see that 3, a, and b are common between the two terms

so let us factor them out

3ab(c+2a)

Hence the factored form is

3ab(c+2a)

I’m pretty sure 17.3 because of you do a^2+b^2=c^2 you get a^2= 10 square root 3 and that in a decimal is 17.3205

Answer:

4x - 6

Step-by-step explanation:

Remember the formula for finding the area of a parallelogram;[tex](base)*(height)=(area)[/tex]

Manipulate the equation such that it is solved for the base;

[tex](base)=\frac{(area)}{(height)}[/tex]

So the equation that needs to be solved is;

[tex]\frac{(8x^{2} + 2x - 6 )}{(2x + 2)}[/tex]

Set up the division problem and solve;

              _____4x - 6___

[tex]2x + 2[/tex]     | [tex]8x^{2} + 2x - 6[/tex]

             [tex]-(8x^{2}+8x)[/tex]

                ________

                       -6x - 6

                      [tex]+ (6x + 6 )[/tex]

                      ________

                              0

Answer: x=7/2, x=-3

Step-by-step explanation:

First lets do look at it without the absolute value marks

4x-1=13

4x=14

x=7/2

Now lets do the same but assume 13 is negative,

4x-1=-13

4x=-12

x=-3

Answer:

Step-by-step explanation:

First, add up the two numbers in the ratio to get 8. Next divide the total amount by 8, i.e. divide £40 by 8 to get £5. £5 is the amount of each 'unit' in the ratio.

To calculate the ratio of an amount we divide the amount by the total number of parts in the ratio and then multiply this answer by the original ratio. We want to work out $20 shared in the ratio of 1:3.

Answer:

[tex]25.1\ \text{inches}^2[/tex]

[tex]56.5\ \text{inches}^2[/tex]

[tex]69.7\ \text{inches}^2[/tex]

Step-by-step explanation:

The length of the pipe is given by the function

[tex]L=119.75\sqrt{A}[/tex]

where A is the area

[tex]A=(\dfrac{L}{119.75})^2[/tex]

For [tex]L=600\ \text{in}[/tex]

[tex]A=(\dfrac{600}{119.75})^2\\\Rightarrow A=25.1\ \text{inches}^2[/tex]

Area watered when L = 600 inches is [tex]25.1\ \text{inches}^2[/tex]

For [tex]L=900\ \text{in}[/tex]

[tex]A=(\dfrac{900}{119.75})^2\\\Rightarrow A=56.5\ \text{inches}^2[/tex]

Area watered when L = 900 inches is [tex]56.5\ \text{inches}^2[/tex]

For [tex]L=1000\ \text{in}[/tex]

[tex]A=(\dfrac{1000}{119.75})^2\\\Rightarrow A=69.7\ \text{inches}^2[/tex]

Area watered when L = 1000 inches is [tex]69.7\ \text{inches}^2[/tex]

Answer:

86%

Step-by-step explanation:

angles in the triangle add up to 180

so we add 75% and 19%

to get 94%

then we subtract 180 by 94%

to get 86%

Step-by-step explanation:

Answer:

Standard form is a way of writing down very large or very small numbers easily. 103 = 1000, so 4 × 103 = 4000. So 4000 can be written as 4 × 10³. This idea can be used to write even larger numbers down easily in standard form. Small numbers can also be written in standard form.

Factored form, the product of a constant and two linear terms: or. The parameters and are the roots of the function (the x-intercepts of the graph ). Converting a quadratic function to factored form is called factoring.

The y -intercept of a graph is the point where the graph crosses the y -axis. (Because a function must pass the vertical line test , a function can have at most one y -intercept . ) The y -intercept is often referred to with just the y -value.

The x-intercept is the point where a line crosses the x-axis, and the y-intercept is the point where a line crosses the y-axis. and vertex is

In geometry, a vertex (in plural form: vertices or vertexes), often denoted by letters such as, is a point where two or more curves, lines, or edges meet. As a consequence of this definition, the point where two lines meet to form an angle and the corners of polygons and polyhedra are vertices.

Answer:

A

Step-by-step explanation:

a²+ b² = c²

(3 ft)² + (9 ft)² = (H)²

Answer:

A

Step-by-step explanation:

in a right triangle, the longest side (across from the right angle) is the hypotenuse (denoted as 'c')

the legs are denoted as 'a' and 'b'

the Pythagorean Theorem allows you to find the missing side using this formula:

a² + b² = c²

Answer:x=√−y2+18y−56 or x=−√−y2+18y−56

Step-by-step explanation:

x2+(y−9)2=25

Step 1: Add -y^2 to both sides.

x2+y2−18y+81+−y2=25+−y2

x2−18y+81=−y2+25

Step 2: Add 18y to both sides.

x2−18y+81+18y=−y2+25+18y

x2+81=−y2+18y+25

Step 3: Add -81 to both sides.

x2+81+−81=−y2+18y+25+−81

x2=−y2+18y−56

Step 4: Take square root.

x=√−y2+18y−56 or x=−√−y2+18y−56

Answer:

x=√−y2+18y−56 or x=−√−y2+18y−56

Answer:

n= 7.5

Answer:

n = 4

Step-by-step explanation:

Properties of Exponents

We are required to solve the following equation:

[tex]\displaystyle 7^7\cdot 7^5=\frac{(7^n)^4}{7^4}[/tex]

Operating:

[tex]\displaystyle 7^{7+5}=\frac{7^{4n}}{7^4}[/tex]

[tex]\displaystyle 7^{12}=7^{4n-4}[/tex]

Equating the exponents:

4n - 4 = 12

Adding 4:

4n = 16

Dividing by 4:

n = 4

Answer:

Q1:     [tex]\frac{1}{x+3}[/tex]

Q2:     [tex]\frac{1}{(x-2)(x+2)}[/tex]

Q3:     [tex]\frac{(x-3)(x+3)}{(x+1)(x+4)}[/tex]

Q4:     [tex]\frac{x(x+2)}{(x-4)^{2}(x+5) }[/tex]

Step-by-step explanation:

If there is a vertical asymptote at x=k, then the denominator must contain a term (x-k) or (x-k) raised to a positive integer power.

If there is an x intercept at k, then the numerator must contain a term (x-k) or (x-k) raised to a positive integer power.

If there is a horizontal asymptote of 0, then the highest power of x in the denominator must exceed the highest power of x in the numerator.

If thee is a horizontal asymptote of k, then the highest power of x in the numerator and denominator must be the same and the ratio of their coefficients (numerator to denominator) must be k.

Answer:

x = 2

y = 6

Step-by-step explanation:

We have a system of equations and are asked to solve for x and y.

y = -2x + 10

y = 3x

Since both equations start with y, we can subtitute.

3x = -2x + 10

Solve for x :

Add 2x to both sides :

5x = 10

Divide 5 from both sides :

x = 2

Now substitute x in the second equation because it's more easier :

y = 3(2)

3(2)

6

y = 6
