You would cross multiply for this.
\frac{20}{50}  =  \frac{x}{35}

20 · 35 = 700
Then you would divide.
700 ÷ 50 = 14

There would be 14 cones placed along 35 feet of road.

Use inverse functions where needed to find all solutions of the equation in the interval [0, 2π). (Enter your answers as a comma
Zina [86]
I'm assuming you meant:

tan^{2}x + tanx - 30 = 0
Let u = tan(x)

Thus, we can rewrite it into a quadratic.

u^{2} + u - 30 = 0
(u + 6)(u - 5) = 0
u = -6 or u = 5

Hence, tan(x) = -6 or tan(x) = 5
x = tan^{-1}(-6) or x = tan^{-1}(5)

Rewriting it in general form, we get:
x = \pi \cdot n + tan^{-1}(5), n \in Z
x = \pi \cdot n - tan^{-1}(6), n \in Z

From there, you can find your solutions from [0, 2\pi)

The formula for the volume of a sphere is V space equals space 4 over 3 Ïr cubed. Find the radius to the nearest hundredth of a
rjkz [21]

Answer:

r = 1.68 ft

Step-by-step explanation:

Volume of a sphere, V = 4/3πr³

V = 20 ft³

π = 3.14

r = ?

V = 4/3πr³

20 = 4/3 × 3.14 × r³

20 = (4×3.14×r³)/3

Cross product

20 × 3 = 4 × 3.14 × r³

60 = 12.56r³

r³ = 60/12.56

= 4.7771

r = 3√4.7771

= 1.6842

Approximately

r = 1.68 ft to the nearest hundredth

Verify that the following equation is an identity. (1/sinx) - (1/cscx) = cscx - sinx
Anarel [89]
Manipulating the left side of the equation, we obtain:

\dfrac{1}{\sin x}-\dfrac{1}{\csc x}=\dfrac{\csc x-\sin x}{\sin x\cdot\csc x}

Using that \csc x=\dfrac{1}{\sin x}:

\dfrac{\csc x-\sin x}{\sin x\cdot\csc x}=\dfrac{\csc x-\sin x}{\sin x\cdot\dfrac{1}{\sin x}}=\dfrac{\csc x-\sin x}{1}=\csc x-\sin x\\\\\boxed{\dfrac{1}{\sin x}-\dfrac{1}{\csc x}=\csc x-\sin x}~~\blacksquare
