Write 2x+3(to the power of 2)+x-4(to the power of 2). Then do the equations and you should get 4x+9+2x+16. Combine like terms and that's your answer. I know it might be weird that it's not like 72 or something, but it's math haha. Your answer should be 6x+25! Make sure you understand this before just writing all of this down. Also, don't be afraid to ask your teacher. They are there to help!

A=pi r^2
A= pi(4^2)
A=pi(16)
A=50.265...ft^2
2A=100.5309...ft^2

C=pi d
C=8pi
C=25.1327...ft^2

25.1327...(50)= 1256.637...

1256.637...+100.5309...=1357.167... so the surface area of the tan is about 1357.2 ft^2

A hiker standing at point G wants to estimate the distance across the lake to point H, which is directly north of her location.
riadik2000 [5.3K]

Answer:

D

Step-by-step explanation:

The diagram is attached.

Looking at the diagram, we want the side "opposite" of the angle given and the side "adjacent" is given.

Which ratio relates opposite and adjacent? It is Tan.

We can use trigonometry and tan ratio to solve for the distance "x":

Tan(84)=\frac{x}{650}\\x=Tan(84)*650\\x=6184.4

D is the correct answer.
