X + 9 = 2x - 8
2x - x = 9 + 8
x = 17

BC = x = 17

answer
17 units

You would set AC and AB equal to each other to find out what x is.

x+9=2x-8
x+17=2x
17=1x
17=x

Since CB is just x, CB equals 17.

Please help solving this ! Which net represents the figure?

Sergeeva-Olga [200]

Answer:

upper right

Step-by-step explanation:

The net for a figure is a representation of all of the figure's faces. The polygons in the net are joined on an edge corresponding to a common edge between the faces they represent.

The given figure is a rectangular prism. Its faces are only rectangles. All nets that have triangles in the net can be eliminated from consideration.

The appropriate choice is the one attached.

Sec^2 theta/tan theta = sec theta x csc theta

Andreas93 [3]

Answer:

see explanation

Step-by-step explanation:

Using the trigonometric identities

• tan x = $\frac{sinx}{cosx}$

• sec x = $\frac{1}{cosx}$ , csc x = $\frac{1}{sinx}$

Consider the left side with x = Θ

$\frac{sec^2x}{tanx}$

= $\frac{1/cos^2x}{\frac{sinx}{cosx} }$

= $\frac{1}{cos^2x}$ × $\frac{cosx}{sinx}$

= $\frac{1}{cosxsinx}$

= $\frac{1}{cosx}$ × $\frac{1}{sinx}$

= secxcscx = right side ⇒ verified

PLEASE HELP ME WITH THIS....

Whitepunk [10]

Answer:

Step-by-step explanation:

The question is faulty. It works once it gets to + 1, +2, +3

The other x values should be 0 and - 1 instead of -1 and -3.

Here's the formula I get.

f(x) = 2*3^(2x + 1)

f(0) = 2*3^(1)

f(0)= 6

f(-1) = 2*3^(-2 + 1)

f(-1) = 2*3^(-1)

f(-1) = 2/3

f(-2) = 2*3^(-2*2 + 1)

f(-2) = 2*3^(-4 +1)

f(-2) = 2*3^(-3)

f(-2) = 2/27

Since my answers do not agree with the given answers, I can do nothing more to help you. I will pass this along to someone I know who will see through it.
