To solve this problem, draw the situation for a better comprehension:
As we can see, the situation describes a right triangle and we can use pythagorean theorem to solve it.
To do this, use the corresponding units.
For inches:
![\begin{gathered} h=\sqrt[]{84^2-48^2} \\ h=\sqrt[]{7056-2304} \\ h=\sqrt[]{4752} \\ h=68.9 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20h%3D%5Csqrt%5B%5D%7B84%5E2-48%5E2%7D%20%5C%5C%20h%3D%5Csqrt%5B%5D%7B7056-2304%7D%20%5C%5C%20h%3D%5Csqrt%5B%5D%7B4752%7D%20%5C%5C%20h%3D68.9%20%5Cend%7Bgathered%7D)
The suspect is 68.9 inches high.
Convert this height to feet:
The suspect is 5.74 feet high.
Answer:
1,000 cm
Step-by-step explanation:
5 x 200 = 1000
First, we need to solve for the common ratio from the data given by using the equation.
a(n) = a(1) r^(n-1)
15 = -3 r^(2-1)
-5 = r
r = -5
Then, we can find the sum by the expression:
S(n) = a(1) ( 1 - r^n) / 1-r
S(8) = -3 (1 + 5^8) / 1+5
S(8) = -195313
If you're taking trig, the "sum and difference formulas for trig functions" are basic facts that you'll need to learn and commit to memory. I'd suggest you look up these formulas on the net. You will likely immediately find listings for the sine, cosine and tangent.
