Sin(a+/-b)=sin(a)cos(b)+/-cos(a)sin(b)
sin(17+26)=sin(17)cos(26)+cos(17)sin(26)
Answer: sin(43)
Answer:
7ygfce
Step-by-step explanation:
The average would be the total amount divided by the 2 groups, so the answer would be 37.5 years old.
Answer:
The period of Y increases by a factor of 
with respect to the period of X
Step-by-step explanation:
The equation 
shows the relationship between the orbital period of a planet, T, and the average distance from the planet to the sun, A, in astronomical units, AU. If planet Y is k times the average distance from the sun as planet X, at what factor does the orbital period increase?
For the planet Y:
For planet X:
To know the factor of aumeto we compared 
with 
We know that the distance "a" from planet Y is k times larger than the distance from planet X to the sun. So:
So
Then, the period of Y increases by a factor of with respect to the period of X
Answer: B: It gets flatter
Step-by-step Explanation:
Slope is basically a ratio of the change in the x-value over the change in the y-value over a certain interval. It also shows how steep the line is. The higher (or further away from 0) the slope, the “steeper” the line is. If the slope is 0, the graph just looks like a horizontal line
