Answer:
Standard Form To change a number from scientific notation to standard form, move the decimal point to the left, or to the right. You should move the point as many times as the exponent indicates. Do not write the power of ten anymore. hope I helped
Step-by-step explanation:
We have been given that a huge ice glacier in the Himalayas initially covered an area of 45 square kilo-meters. The relationship between A, the area of the glacier in square kilo-meters, and t, the number of years the glacier has been melting, is modeled by the equation
.
To find the time it will take for the area of the glacier to decrease to 15 square kilo-meters, we will equate
and solve for t as:



Now we will switch sides:

Let us take natural log on both sides of equation.

Using natural log property
, we will get:










Therefore, it will take
years for area of the glacier to decrease to 15 square kilo-meters.
