Answer:
4/27
Step-by-step explanation:
F(x) = 4(1/3)^x
Let x =3
F(3) = 4(1/3)^3
Exponents first
F(3) = 4 * 1/27
Then multiply
f(3) = 4/27
You have to use the Pythagorean theorem but there is a little twist here since a square has has equal sides. So:
x^2+x^2=8
2x^2=8
2/2x^2=8/2
x^2=4
√x^2=√4
x=2
The side of the square is 2.
So now the area of a square is:
Side×Side
2×2=4
The area of the square is 4 centimetres
Visualize the kite as a triangle, with the point where the kite is anchored being 'A', the kite being 'B', and the point directly below the kite being 'C'. We know that line segment BC is 19 meters, and can use trigonometry to find the length of the string, line segment AB. The operator 'sin' can be calculated by dividing the opposite leg over the hypotenuse, so given the angle 'A', we can solve for the hypotenuse.

. If we solve for 'x', we get

. Plug 19 over sin(33) into your calculator and you get 34.885, so the answer is A, 35 feet
It would be $40.50 because the pens are 27 pounds and the first 20 office supplies are $12, the next 30 are $10, and the remaining 37 would be $18.50
