If g(x ) = 3x - 5, then g -1(x )=
NemiM [27]
G(x) = 3x - 5

let g(x) = y

y = 3x - 5

y + 5 = 3x

3x = y + 5

x = (y + 5)/3

From y = g(x),  x = g⁻¹(y) 

<span>x = (y + 5)/3
</span>
 g⁻¹(y)  = <span>(y + 5)/3</span>

 g⁻¹(x)  = <span>(x + 5)/3</span>

A person gets on a Ferris wheel at the starting point. The starting point is 15 feet off the ground. The Ferris wheel has a radi
lisov135 [29]
<h2>Answer:</h2>

\boxed{\frac{25}{2}(\sqrt{6}+\sqrt{2})+65}

<h2>Explanation:</h2>

<em>The height of the rider from the ground after the Ferris wheel</em> equals <em>the starting point is 15 feet off the ground </em><em>plus </em><em>the radius of the Ferris wheel </em><em>plus </em><em>the opposite side of the triangle ΔABC </em>(See figure below).<em> </em>Hence our goal is to find this side. We have the angle 11\pi /2=165^{\circ}, therefore the angle ∠BAC = 165° - 90° = 75°. So this side can be found using trigonometry:

\overline{BC}=\overline{AB}sin(75^{\circ})=50sin(75^{\circ})=\frac{25}{2}(\sqrt{6}+\sqrt{2})

Finally, the height is:

H=\frac{25}{2}(\sqrt{6}+\sqrt{2})+15+50 \\ \\ \boxed{H=\frac{25}{2}(\sqrt{6}+\sqrt{2})+65}

Give a button and a bookmark
Vanyuwa [196]

Let's note the information.

This is what we know:

Every buttons came in packages of 30 per student.

Every bookmark came in packages of 50 per person.

Know, we need to do some multiplying.

30 x 400 & 50 x 400

Now solve.

30 X 400 = 12000.

So we now know that they have an estimated 12000 buttons total.

Now, we find x for bookmarks.

50 x 400 = 20000

That means total that estimated that 20000 bookmarks will be given.

The length of a rectangle is 6 inches longer than it is wide. If the area is 160 square inches, what are the dimensions of the r
BartSMP [9]

Answer:

L = 16

w = 10

Step-by-step explanation:

Givens

Area = 160 sqr inches

width = x

length = x + 6

Equation

Area = L * w

Solution

Substitute in the equation all of the givens.

160 = x(x + 6)                     Remove the brackets

160 = x^2 + 6x                   Subtract 160 from both sides.

160-160 = x^2 + 6x - 160

0 = x^2 + 6x - 160

This equation factors. Turn it around first

x^2 + 6x - 160 =  0

(x - 10)(x + 16) = 0

Answer

x (width) = 10

x + 16 = 16
