Here's the image. If you want to print it or draw on it, you can.
The equation of the first circle is \((x+3)^2+(y)^2=64\) (red) and the second is \((x+3)^2+(y+2)^2=256\) (blue).
Equations 1 and 4 are correct I think, since a dilation of 2 multiplies the radius of 8 to 16 and all circles are similar.
If you want to use a more intricate music notation website, I use Noteflight. You can use many instruments, you can set dynamics, you can add other markings to the music, and it's been around for over 10 years at this point.
Also, the melody's good, but the bass part feels plastered on instead of mixed in with the melody. Keep working hard though! :D
Sentences 1 and 2 are wrong since P is constant (with heads and tails being equal outcomes) and those are the only 2 outcomes. Sentence 4 should be the right answer since there are 4 trials and there are only two outcomes (with the probability of 1/2 being chosen).
There are 2 traffic lights. If one is green and one is not, we need to multiply the probability that one is green and the probability that one is not.
.6*.4 = 0.24
A logarithm is a way to show the exponent for a base that equals a number.
For example, \((log_28=3) = (2^3=8)\)
The little number under the log is the base of the exponent.
The number next to the little number is the answer to the exponent.
The answer of log is the exponent.
I can draw pictures of it later if you still need assistance.
This question is basically asking what is the shift of f(x)=x+2. The answer to that is 2 to the left.
If you have a TI-84 or 83, you can plug in the numbers into the list then make it visible on a graph. Plug in the equations one by one to see which one fits.
\(y=−56.80x^2+437.91x−65.5\) is probably your best bet
