If f(x) = x - 1 and g(x) = x3, what is (gºf)(8)?

Answer:

Step-by-step explanation:

Domain of a function defines the input values (x-values) of the function.

Given linear function is,

y = -2x - 5

Domain of the function is,

{-6, -5, -2, 0, 1}

By substituting the values of x in the equation we can get y-values (output values).

Input-output table for the function,

x            -6            -5            -2             0             1

y             7             5             -1             -5           -7

Now we can plot these points of the graph.

Answer:

x = 5

Step-by-step explanation:

The area (A) of a triangle is calculated as

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h is height )

Here A = 20, b = (x + 3) and h = (2x - 5) , then

[tex]\frac{1}{2}[/tex] (x + 3)(2x - 5) = 20 ← multiply both sides by 2

(x + 3)(2x - 5) = 40 ← expand left side using FOIL

2x² + x - 15 = 40 ( subtract 40 from both sides )

2x² + x - 55 = 0 ← in standard form

(x - 5)(2x + 11) = 0 ← in factored form

Equate each factor to zero and solve for x

x - 5 = 0 ⇒ x = 5

2x + 11 = 0 ⇒ 2x = - 11 ⇒ x = - 5.5

But x > 0 , so x = 5

Answer:

area = length x width

96/8= 12 = something i have no idea what is breadth, but it doesnt matter

perimeter = 2(length) + 2(width)

2(12) + 2(8)=40cm

hope that answers your question

ps. fix your typing...skill, or word vocabulary thing...

Step-by-step explanation:

Answer:

40 cm

Step-by-step explanation:

Data:

Area (a): 96 cm

Width (b): 8 cm

a = b•h

96 = 8•h

96/8 = h

12 = h

The perimeter is the sum of all the sides, so.

Perimeter:

12+12+8+8 = 40

Answer:

[tex]134.56[/tex]

Step-by-step explanation:

Break 11.6 into addenda.

[tex](11 + 0.6)[/tex]

Apply the binomial expansion method.

[tex](11 + 0.6)(11 + 0.6)[/tex]

[tex]11 {}^{2} = 121[/tex]

[tex]2(11)(0.6) = 13.2[/tex]

[tex]0.6 {}^{2} = 0.36[/tex]

Add them all up and you get.

[tex]134.56[/tex]

Answer:

B

Step-by-step explanation:

The interior angles of a triangle always add up to 180 degrees.

We have two angles already and they add up to 60+63=123 degrees

180-123=57

so the remaining angle is 57 degrees

9514 1404 393

Answer:

  D.  123°

Step-by-step explanation:

The external angle is equal to the sum of the remote internal angles.

  m∠1 = 60° +63°

  m∠1 = 123°

Answer:

5.4 I think sorry if its wrong

Step-by-step explanation:

Answer:

a: m=5/3

b: m=-3/5

Step-by-step explanation:

first, before answering the questions, let's change the line from standard form (ax+by=c), where a and b are free coefficients into slope-intercept form (y=mx+b), where m is the slope and b is the y intercept

subtract 5x from both sides

-3y=-5x+7

divide by -3

y=5/3x-7/3

now to answer part a:

parallel lines have the same slopes, but different y intercepts.

the slope of the given line is 5/3, so therefore, a parallel line to the line y=5/3x-7/3 will also be 5/3

part b:

perpendicular lines have slopes that are negative and reciprocal; if you multiply them together, the result is -1

so to find the slope of a perpendicular line, use this formula:

5/3m=-1

multiply by 3/5 to isolate the variable

m=-3/5

therefore the slope of a perpendicular line will be -3/5

Step-by-step explanation:

the 2nd choice looks good Emily

y > x

y > x+2

y>x and y>x+2 is the  systems of inequalities describes the shaded region in the graph below.

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

A relationship between two expressions or values that are not equal to each other is called 'inequality.

Unless you are graphing a vertical line the sign of the inequality will let you know which half-plane to shade.

If the symbol ≥ or > is used, shade above the line.

If the symbol ≤ or < is used shade below the line.

y>x and y>x+2 is the inequality describes the shaded region in the graph below as it is greater.

Hence, y>x and y>x+2 is the  systems of inequalities describes the shaded region in the graph below.

Answer:

x=8

Step-by-step explanation:

Remember that the variables a and b in the formula are the legs and c is the hypotenuse. So that means that 15 and x are the legs and 17 is the hypotenuse. Plug those numbers where they go in the formula like below:

15^2+x^2=17^2

Go ahead and square the 15 and 17 to simplify it a little.

225+x^2=289

Now, get the x by itself by subtracting 225 from each side

x^2=64

Take the square root of each side to remove the squared on x and solve.

Answer:

The correct answer is A. The actual height of the Eiffel Tower is 301 meters.

Step-by-step explanation:

Given that a model of the Eiffel Tower uses a scale of 1 cm - 4 meters, if the model is 75 1/4 a centimeters tall, to determine what is the actual height of the Eiffel Tower the following calculation must be performed:

1 = 4

1/4 = 0.25

75.25 x 4 = X

301 = X

Therefore, the actual height of the Eiffel Tower is 301 meters.
