To write in the scientific notation, we have to move the decimal point to the left of the number given until it reaches the first number multiply it by ten and raise to a number equal to the number of times you move the decimal point. Therefore, the correct answer is 3.92 x 10^12.
Answer:
-2x + 5y = 25
Step-by-step explanation:
Answer:
A. Yes, because by 2206, the radioactive element remaining in the area is less than 800 Bqs.
Step-by-step explanation:
Function for the amount of radioactivity:
The function for the amount of radioactivity, in t years after 1996, is given by:

Find f(220) to determine the amount of becqurels in 2206.

121.42 < 600, so the area will be safe, and the correct answer is given by option A.
Answer:
44 degrees.
Step-by-step explanation:
Since angle A is 46 degrees, and angle C is 90 degrees (because of the right angle) you add 46 and 90 (you get 136) then subtract it from 180 (since every triangle equals 180 degrees) which gets you to 44 degrees.
Multiply the base which is 18.65 and multiply it by the height which is 9 3/10 and then multiply by half and that estimates to B. 90 cm
