So, the ans is A.........
Answer:
The Y intercept is -5 and the slope is -5/2
Answer:
x=2
ab=7
bc=5
Step-by-step explanation:
because you do
2x+3 = 4x+3
-3 -3
2x=4x
-2x -2x
x = 2
2x2+3
4+3
=7
4x2-3
8-3
=5
<span>Tan(x) = sin(x) / cos(x). Therefore, tan(x) pi/2 = 1/0, which doesn't exist. Imagine that, instead of 0, it's a number incredibly close to 0. The smaller the number in the denominator, the bigger the outcome. Therefore, we can think of 1/0 as infinity, or approaching infinity as one gets closer to 1/0. This is the same result approaching from the negative side, only it's negative infinity. If x=0, it's 0/1 instead (sin 0=0, cos 0=1). Anything divided by 1 is itself, so as x approaches 0, so does f(x).</span>
Answer:
= 2sinA.cosA+ sinA / 1+cos2A+ cosA
= sinA(2cosA + 1) / 2cos^2A + cosA
= sinA(2cosA + 1) / cosA( 2cosA + 1)
= sinA / cosA
= tan A
