At 6:00 PM, a flagpole that is 35 feet tall casts a shadow that is 50 feet long. At the same time, how long will a person's shad
sertanlavr [38]

<u>Answer:</u>

The length of the person’s shadow is 5.7ft

<u>Explanation:</u>

Length of the flagpole =a= 35ft

Length of the shadow of the flagpole= b=50ft

Length of the person=c= 4ft

Suppose the length of the person’s shadow is=d

According to the  rules of trigonometry

\frac{\text { Length of the flagpole }}{\text { Length of the shadow of the flagpole }}=\frac{\text { Length of the person }}{\text { Length of the person's shadow }}

\frac{a}{b}=\frac{c}{d}

\frac{35}{50}=\frac{4}{d}

35d=200

d=\frac{200}{35}

d=5.7ft  

Hence, The length of the person’s shadow is 5.7ft.

Solve -3x2 + 30x - 90 = 0.
FrozenT [24]
-3x^{2}+30x-90=0 \\  \\ x^{2}-10x+30=0 \\  \\ \Delta=(-10)^{2}-4*1*30=100-20=-20 \\  \\  \sqrt{\Delta}= \sqrt{-20}=i \sqrt{20}   =2i \sqrt{5}  \\  \\ x_{1}= \frac{10-2i \sqrt{5} }{2} = 5-i \sqrt{5}   \\  \\ x_{2}= \frac{10+2i \sqrt{5} }{2} = 5+i \sqrt{5}

Water is being poured into a container in the shape of a right circular cone with a radius of 4 ft and height of 16 ft. Find a f
zmey [24]

Answer:

V=pi*\frac{16 h}{3}

Step-by-step explanation:

Volume of a right circular cone can be found using the equation

V=pi*\frac{r^{2} h}{3} where

  • r is the radius of the cone
  • h is  the height of the cone
  • pi is the π constant

Since r=4ft, we can model the volume of the water in the cone in terms of the height as

V=pi*\frac{4^{2} h}{3} =pi*\frac{16 h}{3}
