180 degrees means that the new x=-x and the new y=-y so
x=3 and y=-5 is orignal
new is -3 and 5
so new oint is
A(-3,5)
Answer: 28/r+4
Step-by-step explanation: Divide each term by r + 4 and simplify
Step-by-step explanation:
Given :
1- cosA = 1/2
or, CosA = 1 -1/2
Therefore ; CosA = 1/2 = b/h
According to the Pythagoras theorem,
P = root under h^2 - b^2
= root under (2)^2 - (1)^2
= root under 4 -1
= root 3
Again,
SinA = P/h
= root 3 / 2
Answer:
says of the week
Step-by-step explanation:
x side or bottom of graph is independent variable
y side of left part of the graph is dependent variable
Replace x with 1/2 and solve.
49^1/2 = sqrt(49) = 7
