Answer:

Composition:   [tex]f(x)\,^o\,h(x)=4\,\sqrt{x+4} -1[/tex]

Domain = { [tex]x\,/\,x\geq \,-4[/tex]  }

Step-by-step explanation:

Given

[tex]f(x)=4\,x-1\,\,\, and \,\,\, h(x)=\sqrt{x+4}[/tex]

The requested composition becomes:

[tex]f(x)\,^o\,h(x)=f(h(x))\\f(x)\,^o\,h(x)=f(\sqrt{x+4} )\\f(x)\,^o\,h(x)=4\,\sqrt{x+4} -1[/tex]

Then the Domain consists of all Real x-values for which the function is defined. In this case, the function is defined for all x-values for which the square root is defined, that is all x values for which:

[tex]x+4\geq \,0[/tex]  (so the square root is defined in the Real number system)

This means [tex]x\geq \,-4[/tex]

The Domain is then all the Real x-values such that [tex]x\geq \,-4[/tex]

Answer:

Step-by-step explanation:

green tiles you add the x

red tiles is for subtraction

2x-2= 3x + 6 -2x-2

x on one side and numbers on other

2x-3x+2x=6-2+2

-3x=6

x=6/-3 =-2

Step-by-step explanation: Our first task in this problem is to setup variables representing length and width and we do that by using the second sentence.

The length is twice the width

So if we call our width x, that means that our length is 2 times x or 2x

Width of the rectangle ⇒ x

Length of the rectangle ⇒ 2x

Before moving on, go ahead and draw a picture of your

rectangle so that you can visualize what's going on.

I have done this for you below.

We label our widths x and our lengths 2x.

Now we can use the first sentence to setup our equation.

The perimeter of a rectangle is the distance

around the outside of the figure.

So if our perimeter is 60, that means that x + x + 2x + 2x = 60.

Simplifying by combining like terms, we get 6x = 60.

Now dividing both sides by 6, we find that x = 10.

Since x represents width, our width is 10.

Our length therefore with be 2(10) or 20.

So our width is 10 and our length is 20.

Answer:

B

Step-by-step explanation:

If you switch the x and y you can solve for the inverse by solving for y like this:

x=3y+5

3y=x-5

y=(x-5)/3

which can be rewritten as B.

Answer:

[tex]y=4x^2+12x+9[/tex]

Step-by-step explanation:

Perform the square of the binomial, combine like terms, and then write the remaining expression in decreasing order of powers of x:

[tex]y=(2x+3)^2\\y=(2x+3)\,(2x+3)\\y=4x^2+6x+6x+9\\y=4x^2+12x+9[/tex]

Answer:

x= 50°

Hope it helps!

Step-by-step explanation:

The sum of the exterior angles of a polygon is always 360°

So, x+40+x+20+2x+2x = 360

6x + 60= 360

6x = 360-60 = 300

6x= 300

x= 300/6

= 50

Answer:

[tex]S.D = 15.98[/tex]

Step-by-step explanation:

Given: 76,45,64,80,92

Required: Determine the standard deviation

We start by calculating the mean

[tex]Mean = \frac {\sum x}{n}[/tex]

Where x-> 76,45,64,80,92 and n = 5

[tex]Mean = \frac {76+45+64+80+92}{5}[/tex]

[tex]Mean = \frac{357}{5}[/tex]

[tex]Mean = 71.4[/tex]

Subtract Mean (71.4) from each of the given data

[tex]76 - 71.4 = 4.6\\45 - 71.4 = -26.5\\64 - 71.4 = -7.4\\80 - 71.4 = 8.6\\92 - 71.4 = 20.6[/tex]

Determine the absolute value of the above result

[tex]|4.6| = 4.6\\|-26.5| = 26.5\\|-7.4| = 7.4\\|8.6| = 8.6\\|20.6| = 20.6[/tex]

Square Individual Result

[tex]4.6^2 = 21.16 \\26.5^2 = 702.25\\7.4^2 = 54.76\\8.6^2 = 73.96\\20.6^2 = 424.36[/tex]

Calculate the mean of the above result to give the variance

[tex]Mean = \frac {\sum x}{n}[/tex]

[tex]Mean = \frac{21.16 + 702.25 + 54.76 + 73.96 + 424.36}{5}\\Mean = \frac{1276.49}{5}\\Mean = 255.298[/tex]

Hence, Variance = 255.298

Standard Deviation is calculated by [tex]\sqrt{Var}[/tex]

[tex]SD = \sqrt{255.298}[/tex]

[tex]S.D = 15.9780474402[/tex]

[tex]S.D = 15.98 (Approximated)[/tex]

Closest answer I could get was 12

Answer:

5.75 cm²

Step-by-step explanation:

→ Utilise the area of a triangle formula

Area of a triangle = 0.5 × Base × Height

→ Identify base and height in the triangle

Base = 4.6 cm

Height = 2.5 cm

→ Substitute in the values into the area of a triangle formula

Area of a triangle = 0.5 × 4.6 × 2.5

→ Simplify

Area of a triangle = 5.75 cm²

Area of a triangle = 1/2 x base x height

= 1/2 x 4.6 x 2.5

= 5.75 sq. cm

Answer:

4.) x=-3 and y=4

Step-by-step explanation:

[x+4] + [-9x] = [28]

First plug in x into the equation

[-3+4] + [-9(-3)] = [28]

[1] + [27] = [28]

1+27=28 (True)

Next, plug in y into the equation

[y^2+1] + [-17] = [0]

[(4)(4)+1] + [-17] = [0]

[16+1] + [-17] = [0]

[17] + [-17] =[0]

17 + -17=0 (True)

Answer:

-2sqrt5

Step-by-step explanation:

Lets begin by simplifying the radicals.

20 can be factored into 4*5, and since 4 is a perfect square, we can take out a 2.

therefore:

sqrt20 = 2sqrt5

80 can be factored into 16*5, and since 16 is a perfect square, we can take out a 4

therefore:

sqrt80 = 4sqrt5

So finally we have, 2sqrt5-4sqrt5 = -2sqrt5

The solution for the difference of √20 - √80 is,

⇒ - 2√5

We have to given that,

An expression is,

⇒ √20 - √80

We can simplify it as,

⇒ √20 = √5 × 4

           = 2√5

⇒ √80 = √16 × 5

           = 4√5

So, We can write as,

⇒ √20 - √80

⇒ 2√5 - 4√5

⇒ √5 (2 - 4)

⇒ - 2√5

Therefore, The required solution is,

⇒ - 2√5

Answer:

Step-by-step explanation:

First, you distribute the 4 and 7 to the stuff inside the parentheses 28 - 12x = 28 - 14x then add 28 to both sides -12x = -14x then add 14x to both sides 2x = 0 then divide both sides by 2 x = 0

Answer:

x=0

Step-by-step explanation:

4(7-3x)=7(4-2x)

Distribute

28 -12x = 28 -14x

Subtract 28 from each side

-12x = -14x

Add 14x to each side

-12x+14x = -14x+14x
