3.331 , 3.313 , 3.133 , 1.333
Step-by-step explanation:
because it just is that way
Answer:
Step-by-step explanation:
Simple interest is
I=Prt, where I= interest, P=principle (initial value), r=interest rate, t=time
I=200(0.052)3
I=$31.20
Answer:
Option (1)
Step-by-step explanation:
By the inscribed angle theorem inside a circle,
"Measure of an inscribed angle is half the measure of the intercepted arc"
[m(arc AB)] = m(∠ABC)
m(arc AB) = 2[m(∠ABC)]
x = 2(41°)
x = 82°
Option (1) is the correct option.
Answer:
![y = 2.cos(x) - 2](https://tex.z-dn.net/?f=y%20%3D%202.cos%28x%29%20-%202)
Step-by-step explanation:
1. Shifting
right or left, top or down, as the graph in the question has the same illustration of
. Consider
![y = a.cos(x) + b](https://tex.z-dn.net/?f=y%20%3D%20a.cos%28x%29%20%2B%20b)
2. find a and b by using two sample points from the graph:
and ![(\pi, -4)](https://tex.z-dn.net/?f=%28%5Cpi%2C%20-4%29)
![0 = a.cos(0) + b => a + b = 0\\ -4 = a.cos(\pi) + b => b-a=-4\\\left \{ {{2b=-4} \atop {2a=4}} \right.\\a = 2, b=-2\\](https://tex.z-dn.net/?f=0%20%3D%20a.cos%280%29%20%2B%20b%20%20%3D%3E%20a%20%2B%20b%20%3D%200%5C%5C%20-4%20%3D%20a.cos%28%5Cpi%29%20%2B%20b%20%3D%3E%20b-a%3D-4%5C%5C%5Cleft%20%5C%7B%20%7B%7B2b%3D-4%7D%20%5Catop%20%7B2a%3D4%7D%7D%20%5Cright.%5C%5Ca%20%3D%202%2C%20b%3D-2%5C%5C)
