Answer:

4.2*10^{-1}

Step-by-step explanation:

We want to simplify:

2.1*10^{-3}\times 2*10^2

We rewrite to get:

2.1*2*10^2*10^{-3}\times10^2

We now apply the laws of indices

4.2*10^{-3+2}

We simplify to get 4.2*10^{-1}

We leave our final answer is scientific form.

The final answer is therefore:

4.2*10^{-1}

Find tan if sin theta= 1/4 and falls in Quadrant 2.
7nadin3 [17]
If sinα=1/4 and it is in q2 it means that the x coordinate is negative.

The triangle has a height of one and a hypotenuse of 4 so:

x=-√(4^2-1)

x=-√15

so tanα=-1/√15

tanα=-√(1/15)

tanα≈ -0.258

Given that ∠A and ∠B are supplementary, Daisy conjectured that ∠A≅∠B .
dexar [7]
When two angles are supplementary, that means that the sum of their individual angles is equal to a straight line, which is 180°. If you add another restriction where the two supplementary angles are equal, then each vale of the angle constitutes half of 180°. Then, that means that ∠A = ∠B = 90°. The answer is C.
