Answer:

Use conversion:

1 square foot = 144 square inches.

As per the statement:

The cost of painting a circular traffic sign is $3.50 per square foot.

⇒Cost of painting a traffic sign = $0.025 square inches.

It is also given that: Diameter measures 36 inches.

Area of a circle is given by:

A = \pi r^2

where r is the radius of the circle.

Diameter = 2r

⇒36 = 2r

Divide both sides by 2 we get;

r = 18 inches

then;

A = \pi (18)^2 = 3.14 \cdot 324 = 1,017.36 square inches.

1 square inches  = $0.025

then;

In 1,017.36 square inches = 0.025 \cdot 1,017.36 = \$24.7275

Therefore, $25 ( to the nearest dollar) will it cost to paint the sign if its diameter measure 36 inches.

A baseball is thrown at an angle of 30° with respect to the ground and it reaches the ground in 2 seconds. What is its initial v
NeTakaya

Answer:

The answer to your question is vo = 19.62 m/s

Step-by-step explanation:

Data

angle = α = 30°

time = t = 2 s

vo = ?

g = 9.81 m/s²

Formula

                  t = \frac{2vosin\alpha}{g}

Solve for vo

             vo = \frac{tg}{2sin\alpha}

Substitution

            vo = \frac{(2)((9.81)}{2sin 30}

Simplification

           vo = \frac{19.62}{2(0.5)}

           vo = \frac{19.62}{1}

Result

            vo = 19.62 m/s
