Step-by-step explanation:
AC=AB+BC-cos. AC=100+66-cos. AC=166-0.906. AC=√165.094. AC=12.8
Answer:
Option D (8,4)
Step-by-step explanation:
we know that
The dilation centered at the origin (0,0) is very simple. To find out the image point multiply the scale factor to the x and y-coordinates of the pre-image point.
so
(2*4,2*2) -----> (8,4)
Answer:
Step-by-step explanation:
3 2/5
Equation of the line joining the points R(-1,6) and S(5,5)
Answer:
B
Step-by-step explanation:
Using the rule of exponents
⇔ ![\sqrt[n]{a^{m} }](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Ba%5E%7Bm%7D%20%7D)
Given
f(x) = 
, then when x = 
f( ) = 
= ![\sqrt[2]{16}](https://tex.z-dn.net/?f=%5Csqrt%5B2%5D%7B16%7D)
= 4
