Svetach [21]3 years ago

From 0 years to 1 year:
91-70 = 21

21 / 91 = 0.23 = 23%

From 1 year to 2 years:
70-54 = 16

16 / 54 = 0.29 = 29%

 because the percentages are different, it isn't linear. This would be an exponential equation.

The answer is C. because you would multiply the starting population (91) by a percentage of decline raised tot he power of the number of years, as shown in the equation for C.

The length of a rectangle is twice it’s width. If the area of the rectangle is 72ft ^2, find it’s perimeter
alisha [4.7K]

Hi!

length = l = 2 * width = 2 * w

Area = l * w = l * 2 * l = 2 * l^2

2 * l^2 = 72

l^2 = 72/2 = 36

l = square root of 36

l = 6

l = 2 * w => w = l/2 = 6/2 = 3

Perimeter = 2 * l + 2 * w = 2 * 6 + 2 * 3 = 12 + 6 = 18 feet

Hope this helps!

goldenfox [79]

Answer:

hopefully tht example will help u

Step-by-step explanation:

To change 0.0002 to scientific notation, move the decimal to the right 4 places so that you get 2. The exponent on the base 10 will be -4 because the decimal was moved to the right 4 places. So 0.0002 in scientific notation is 2×10−4.

2. Rich wrote a novel that sells for n dollars each. He received a bonus of $50,000 to sign the
Yuki888 [10]

The equation which represent total amount of income he earns from selling book is,  A=50000+\frac{109}{100}bn

Since, Selling price of one novel is n dollars

So, selling price of b books is,  n*b=nb

Since, he receives 9% commission on each book sale.

So, total commission he receives on selling of b books is,

                                      nb*\frac{9}{100}=\frac{9}{100}nb

And  also he received a bonus of $50,000 to sign the  contract to write the book,

So, total amount of income he earns is represented by A,

                  A=50000+bn+\frac{9}{100}bn\\\\A=50000+\frac{109}{100}bn
