There are four quadrants of the Cartesian plane: I, II, III and IV. In this case, the point (10,-9) lies on the positive x-axis and on the negative y-axis. This premises are equivalent to the definition of the axes of D. Quadrant IV. The answer to this problem is quadrant IV>

The upper left quadrant is I (1), the upper right is II (2), lower left is III (3), and lower right is IV (4).

Hello, I am a little confused about this problem. Would you mind helping me?

Given the following expression:

$(8q^9)^{-4}$

To simplify the expression, we will use the following rules:

$\begin{gathered} (a^m)^n=a^{m*n} \\ a^{-m}=\frac{1}{a^m} \end{gathered}$

So, the given expression will be as follows:

$(8q^9)^{-4}=8^{-4}*q^{9*-4}=\frac{1}{8^4}q^{-36}=\frac{1}{4096}q^{-36}$

So, the answer will be the second option

35% of a number is what fraction of that number?

shepuryov [24]

35% of a number (say, x) is 35% * x.

35% can be written as a fraction, too. % means /100, so 35% is 35/100 which simplifies to 7/20.

So, 35% * x = 7/20 * x

AC is tangent to circle o at point C.<br>What is the measure of <OAC

erica [24]

Step-by-step explanation:

When a line is tangent to a circle, the part where the radius meets with the line of tangency will be a right angle. Since we know this, we know that ∠C is equal to 90°. We also know that all of the angles in a triangle will add up to be 180°.

We can now add up the two angles we know and subtract it from 180° to get the measurement of ∠OAC.

$90+63=153$

$180-153=27$

∠OAC = 27°
