This expression is equivalent to:
[ 7^(log to the base 7 of 3)]^(-2), or [3]^(-2)], or 1/9.

Answer:
- sin(Z) = 9/15 = 3/5
- cos(Z) = 12/15 = 4/5
Step-by-step explanation:
The hypotenuse is the longest side, XZ (15). It is opposite the right angle (Y).
The segments adjacent to Z are the ones with Z in their name: ZX and ZY. When we talk about the "side" or "leg" adjacent to Z, we are usually not interested in the hypotenuse ZX. We refer to that as the "hypotenuse." So, the side or leg "adjacent" to Z is ZY, of length 12.
The segment opposite to Z is the one that does not have Z in its name: XY.
sin(Z) = Opposite/Hypotenuse = XY/XZ = 9/15 = 3/5
cos(Z) = Adjacent/Hypotenuse = YZ/XZ = 12/15 = 4/5
Answer:
11 cm
Step-by-step explanation:
1m = 100cm
By examining the graph carefully, we can see that the record in 1985 is 2.4 m. In 1970 it was slightly under 2.3 m. For it to be 15cm it would have to be 2.25m. For it to be 9 cm it would the record would have been above 2.3m.
Answer:
1/169
Step-by-step explanation:
The probability of drawing a 3 in a 52 card deck is 4/52 which can be simplified to 1/13.
The probability of then drawing a jack is 4/52, also simplified to 1/13. It doesn't matter of you want to put jack or 3 first, there are 4 of each in a deck.
1/13*1/13=1/169
