A local park is building a sand volleyball court 40 feet long and 15 feet wide. They are paying $3000 to have the sand put into

andrew-mc [135]

Answer:

The court cost $5 per square foot of sand

Step-by-step explanation:

step 1

Find the area of the volleyball court

The area of the rectangular court is equal to

$A=LW$

we have

$L=40\ ft$

$W=15\ ft$

substitute

$A=(40)(15)=600\ ft^{2}$

step 2

Divide the total cost to have the sand put into the court by the area of the court

$\frac{3,000}{600}\frac{\$}{ft^{2}}=5\frac{\$}{ft^{2}}$

therefore

The court cost $5 per square foot of sand

Find the exact value of each of the following. In each case, show your work and explain the steps you take to find the value.

mote1985 [20]

Answer: a) $\frac{1}{2}$

b) 1

c) 2

Step-by-step explanation:

(a) sin 17π/6

It is known that the value of sin x repeat after an interval of $2\pi\ or\ 360^{\circ}$

∴ $\sin\frac{17\pi}{6}=\sin2\frac{5\pi}{6}=\sin(2\pi+\frac{5}{6}\pi)=\sin{\frac{5}{6}\pi}=\sin(\pi-\frac{\pi}{6})=\sin(\frac{\pi}{6})=\frac{1}{2}$

[Since the value of sin x is positive in 2nd quadrant]

(b) tan 13π/4

It is known that the value of sin x repeat after an interval of $\pi\ or\ 180^{\circ}$

∴ $\tan\frac{13\pi}{4}=\tan(3\pi+\frac{\pi}{4})=\tan{\frac{\pi}{4}}=1$

(c) sec 11π/3

$\text{Since, }\sec(x)=\frac{1}{\cos x}$

$\cos(\frac{11\pi}{3})=cos(\frac{5\pi}{3}+2\pi)=\cos(\frac{5\pi}{3})=\cos(6\pi-\frac{\pi}{3})=\cos(\frac{\pi}{3})=\frac{1}{2}\\\Rightarrow\sec(\frac{11\pi}{3})=\frac{1}{\cos(\frac{11\pi}{3})}=2$
