Answer:
LHS.= Sin 2x /( 1 + cos2x )
We have , sin 2x = 2 sinx•cosx
And. cos2x = 2cos^2 x - 1
i.e . 1+ cosx 2x = 2cos^2x
Putting the above results in the LHSwe get,
Sin2x/ ( 1+ cos2x ) =2 sinx•cosx/2cos^2x
=sinx / cosx
= Tanx
.•. sin2x/(1 + cos2x)= tanx
Step-by-step explanation:
You multiply 5 times 10, which gives you 50. This is the length of one side. Since it's a square, all sides are the same length.
Answer: 50cm x 50cm
Answer:
f(-3) = 16
Step-by-step explanation:
You substitute -3 to x.
f(-3) = 2(-3)² - 5(-3) - 17
f(-3) = 16.
As for the coordinates, the coordinates plotted in the graph above are (1,-1) and (2,-2).
Answer: I think it is 12.375 ft
Step-by-step explanation: I multiplied the two numbers together. I’m not sure if this is right! Sorry if it isn’t!
Answer:
C. 42
Step-by-step explanation:
<em>PEMDAS</em>
1. Parentheses: (4 + 2) = <em>6</em>
6² + 3 • 2
2. Exponents: 6² = <em>36</em>
36 + 3 • 2
3. Multiplication/Division: 3 • 2 = <em>6</em>
36 + 6
4. Addition/Subtraction: 36 + 6 = <em>42</em>
