D. a piece of a line that starts at the endpoint and extends indefinitely in one direction
think of an arrow with a dagger on one end! :)
Cos 52 = 0.6157
sin 42 = cos 48 = 2/3 (because 42 + 38 = 90 - complementary angles)
if tan 20,5 = 3/8 then tan 69.5 wil = 1 / 3/8 = 8/3
E
If the pre-image is dilated, the image must be congruent to the pre-image.
Volume of a cylinder is π * r^2 * h
so 3^2 * 7 * π = 9 * 7π = 63π cm^3
The answer is D.
Answer:
8^4
Step-by-step explanation:
Here we have:
8^6 · 8³
-------------
8^5
That's multiplication in the numerator. The appropriate rule of exponents states that:
8^a·8^b = 8^(a+b), so the numerator is equivalent to 8^(6 + 3) = 8^9.
Now we have
8^9
------
8^5
and the appropriate rule for division here is
8^a / 8^b = 8^(a - b)
So our:
8^9
--------- 8^(9-5) = 8^4
8^5
