Step-by-step explanation:

The only way to solve this equation is to get the square root:

x^2 = 81

[tex]\sqrt{x^2}[/tex] = [tex]\sqrt{81}[/tex]

Answer:

[tex]h(x)=6x^2+4x[/tex]

Step-by-step explanation:

As the rectangle's length, f(x), is 2 more than three times a unit length, x, so,

f(x)=3x+2

As the rectangle's width, g(x), is twice the unit length, x, so,

g(x)=2x.

The length and width of the rectangle are related to the area and the perimeter of the rectangle. So, the length, f(x), and the width, g(x), can be combined to give the area or perimeter, h(x).

So, h(x) might be the area or the perimeter of the rectangle.

If h(x) is the area, then

[tex]h(x)=f(x) \times g(x)[/tex] [as area=lenght x width]

[tex]\Rightarrow h(x)=(3x+2)\times 2x[/tex]

[tex]\Rightarrow h(x)=6x^2+4x[/tex] (this is in the given options)

If h(x) is the perimeter, then

[tex]h(x)=2\{f(x) + g(x)\}[/tex] [as perimeter=2(lenght + width)]

[tex]\Rightarrow h(x)=2\{(3x+2)+ 2x\}[/tex]

[tex]\Rightarrow h(x)=2(5x+2)[/tex]

[tex]\Rightarrow h(x)=10x+4[/tex] (not in the given options)

So, from the given options [tex]h(x)=6x^2+4x[/tex] is correct.

Answer:

h(x) = 6x^2 + 4x

Step-by-step explanation:

Got it right on lesson.

Answer:

Substitute –3 for x and 5 for h in the difference quotient.

Step-by-step explanation:

The difference quotient for the function f(x) is  21x² + 21xh + 7h² + 2. Now, we know that the difference quotient equal f(x + h) - f(x) = 21x² + 21xh + 7h² + 2. The change in x is h = x₂ - x₁. So, if x changes from x = -3 to x = 2,  where x₁ = -3 and x₂ = 2, h = x₂ - x₁ = 2 - (-3) = 2 + 3 = 5.

So to find the average rate of change of f(x) from x = -3 to x = 2, we substitute x = -3 and h = 5 into the difference equation  f(x + h) - f(x) = 21x² + 21xh + 7h² + 2. Since, x starts at x = -3 and increases by 5 units to x = 2.

Answer:

(on edge) B. Substitute –3 for x and 5 for h in the difference quotient.

she has $1,800

Step-by-step explanation:

to solve we divide 2,400 by 8, which is the total amount of the 2 together. then we get 300 per share, and so we multiply that by kim's 6. to check, we can do 2(300)+6(200) which gives us our origional value of 2,400.

Answer:

We call base 2 the constant ratio. In fact, for any exponential function with the form f(x)=abx f ( x ) = a b x , b is the constant ratio of the function. This means that as the input increases by 1, the output value will be the product of the base and the previous output, regardless of the value of a.

Step-by-step explanation:

Notice from the table that:

the output values are positive for all values of x

as x increases, the output values increase without bound

as x decreases, the output values grow smaller, approaching zero

The graph below shows the exponential growth function

Answer:

The length of the third side is √73

Step-by-step explanation:

To find the third side, we use the Pythagorean Theorem: a² + b² = c²

a² and b² are the two smaller sides

c² is the longest side

The two shortest sides are 4√2 and ?

The longest side is 9

a² = 4√2²

b² = ?

c² = 9²

Now we put together the equation:

4(√2)² + b² = 9²

The square of √2 is 2

4 × 2 + b² = 9²

Multiply 4 and 2 to get 8

8 + b² = 9²

Calculate 9 to the power of 2 and get 81

8 + b² = 81

Subtract 8 from both sides

8 + b² - 8 = 81 - 8

Subtract 8 from 81 to get 73

b² = 73

Take the square root of both sides of the equation

√b² = √73

Simplify

b = √73

Length of third side: √73

Answer:

X=28

Step-by-step explanation:

Answer:

28

Step-by-step explanation:

A triangle always has 180° so that means 40° (2x+9)° and another angle add up to 180°.

We can find out two angles in order to find out the third, one of them is 40°  the other is 180°-105° because there are 180° on a line.

you get 75.

75°+40°=115°

180°-115°=65°

2x+9=65°

Make x the subject of the formula:

2x=56

(take away 9)

x=28

(divide both sides by 2)

Answer:

(x-2)^2/4 - (y+1)^2/16 = 1

Step-by-step explanation:

The first thing you want to do is find the center of the hyperbola. Since you have the two equations of the asymptotes, their intersection must be what you want. setting 2x - 5 equal to -2x + 3, you get that x = 2, meaning that 2 is the x-coord of your center. Plugging this value of x into the equations, you get that y = -1. Now that you have your center, you have the information that one of the vertices is on the y-axis. Since the distance from the center to the vertice must be a straight line, you know for sure that this hyperbola is a horizontal one (a vertical one would not have a vertice on the y-axis given this center). Knowing this, you have the equation form (x-2)^2/a^2 - (y+1)^2/b^2 = 1. I got a little confused here, but remember that you now know the center and the equations of the asymptotes. y = 2x - 5 is equal to 2(x - 2) - 1. The form of the asymptotes of a horizontal hyperbola is b/a(x-h) + k, which means that b/a must be equal to 2. This also means that 2a = b, and 4a^2 = b^2. Now you can substitute b^2 for 4a^2, leaving you with the equation (x-2)^2/a^2 - (y+1)^2/ 4a^2 = 1. Remember that vertice on the y-axis? Since it must be at the same y-coordinate (since you know that it must be a horizontal line from the center to the vertice), you know the vertice has to be (0, -1). You can plug these values into the previous equation, which gives you (0 - 2)^2 / a^2 - 0 = 1. This leaves you with 4/a^2 = 1, which means that a must be 2. Since you already know that b is 2a, b must be equal to 4. Plugging those values into the equation, you get your final answer, (x-2)^2/4 - (y+1)^2/16 = 1.
