Assuming that this is a linear relationship you must find the rate of change...$23.81-$20.70= $3.11. 3.11 is how much it changed that year. What that also gives you is how much you bought the post for at 0 years by subtracting $20.70 and the $3.11 = the price of the poster. This gives us the equation y=3.11(x)+17.59
Where Y is the value and X is the amount of years.
-1.5 + k is the same thing as k - 1.5
and if we want to get k all by itself, we need to add 1.5 on both sides, not add -1.5
so
-1.5 + k = 8.2
-1.5 + 1.5 + k = 8.2 + 1.5
k = 8.2 + 1.5
k = 9.7
If i am correct i think it is 3× = 78 +×-2 idk but i think it that hopefully u get it right :)
First we'll figure out how much he spent. $25 times 8 (weeks)= $200.
Then we subtract that $200 from the total $500.
$500-$200=$300.
A. Trent has $300 left in his saving
Better to write that as:
-1
cos [ sqrt(3) / 2 ]
since the cosine is defined as "adjacent side over hypotenuse," we know that the adj. side is sqrt(3) and that the hyp is 2. The primary solution will be in Quadrant I because the adj. side is positive.
Think: which angle in Q I has adj. side equal to sqrt(3) and hyp equal to 2?
That'd be 30 degrees. Unfortunately, that's not one of your answer choices. Thus, reflect that angle in the positive x-axis; you'll end up with a ray whose positive angle is 330 degrees.
I'd suggest you ensure that you've copied this problem down correctly.
sqrt(3)
Did you mean sqrt(3/2) or did you mean ---------- ??
