Take 180 and subtract the sum of the two given angle, the answer is 62
Answer:
A
Step-by-step explanation:
10 and 8 are equal
11 and 15 are equal
due to the fact that the angles 10 and 11 but also 8 and 15 are supplementary, we know that they add up to be 180 degrees
180-42=138 degrees
and this means that angle 8 will also be 138 because of what we established earlier
*Not 100% sure what you want but here goes*
Step-by-step explanation:
So what you do is create a table for this example label the x values say -2 through 2. Then you plug in the x value to the equation so for 2 its <u>y=</u><u> </u><u>2</u><u>(</u><u>2</u><u>)</u><u>+</u><u>5</u> which is 9. Continue this for the rest of the graph and that should do it.
Hope this helps
Answer:
There will be 22.5 grams left after 32 hours.
Step-by-step explanation:
A half-life is how long it takes for half of the amount to go away. In this case, we see that we have two half-life periods worth, which you can determine by dividing the total time by the half-life time.
32hrs/8hrs = 4 half lives.
Now we can raise 1/2 to the power of how many half lives we have (2). Then we multiply that by the amount in the sample.
(1/2)^4 * 360
1/16 * 360
22.5 grams
And this is an exponential function.
