If you mean 2x=40 x=20
but if you mean x^2=40 i think its x=80

You have to divided by 2 on both sides and you get x=20. Checking your answer you multiply 20 by 2 which is 40.

Solving #19

<u>Take y-values from the graph</u>

a) (g·f)(-1) = g(f(-1)) = g(1) = 4
b) (g·f)(6) = g(f(6)) = g(2) = 2
c) (f·g)(6) = f(g(6)) = f(5) = 1
d) (f·g)(4) = f(g(4)) = f(2) = -2

[Right Triangles Only] SOHCAHTOA
[Right Triangles Only] tanθ = opposite over adjacent

Step-by-step explanation:

<u>Step 1: Identify Variables</u>

Angle θ = 40°

Opposite Leg = <em>x</em>

Adjacent Leg = 21

<u>Step 2: Solve for </u><em><u>x</u></em>

Substitute in variables [tangent]: $\displaystyle tan(40^\circ) = \frac{x}{21}$
[Multiplication Property of Equality] Isolate <em>x</em>: $\displaystyle 21tan(40^\circ) = x$
Rewrite: $\displaystyle x = 21tan(40^\circ)$
Evaluate: $\displaystyle x = 17.6211$
Round: $\displaystyle x \approx 17.6$

mojhsa [17]

Answer:

V = 4/3 x pi x r^3

972 x pi= 4/3 x pi x r^3

729 = r^3

The cubic root of 729 is 9 because 9 x 9 x 9 = 729.

The radius is 9 inches, and the diameter is 18 inches.

The volume of the box is 18 in x 18 in x 18 in or 5832 in.³.
