Answer:
emissions = 40·0.65^t
Step-by-step explanation:
The decay factor in an exponential equation is 1+(decay rate), so the equation can be written ...
amount = (initial amount)×(decay factor)^t
where the decay factor applies to 1 unit of time t. Filling in the given values, we find ...
decay factor = 1 +(-35%) = 0.65 . . . . for 1 year
emissions = 40×0.65^t . . . . . million tons, for t in years
Answer: 4:12
Explanation:
DescriptionIn mathematics, a ratio indicates how many times one number contains another. For example, if there are eight oranges and six lemons in a bowl of fruit, then the ratio of oranges to lemons is eight to six.
Step-by-step explanation:
If you have a co-ordinate plane with you, it will greatly help.
First, move -9.5 units to the left.
Then, move 8 units up.
You will most likely land on a line. If you don't, try it again.
If you do, put your point right there!
Answer: (the function is 8^X, not 8X.)
Step-by-step explanation:
X = 1 8^X = 8
X = 2 8^X = 64
X = 3 8^X = 512
X = 4 8^X = 4096
a. factor A = x^2 -30x + 225 = (x - 15)(x - 15)
side length =<u> (x - 15)</u>
b. add (x - 15) four times = 4(x - 15) =<u> 4x - 60</u>
