The perimeter of a trapezoid is 39a-7. Three sides have the following lengths : 9a, 5a + 1 and 17a -6

Assoli18 [71]

The length of fourth side is: 8a-2

Step-by-step explanation:

Given

Perimeter = P = 39a-7

$Side1 = s_1 =9a\\Side2=s_2=5a+1\\Side3=s_3=17a-6\\Side4=?$

The perimeter is given by:

$P = s_1+s_2+s_3+s_4\\39a-7 =9a+5a+1+17a-6+s_4\\39a-7=31a-5+s_4\\s_4=39a-31a-7+5\\s_4=8a-2$

The length of fourth side is: 8a-2

A wildlife biologist determines that there are approximately 200 deer in a region of a national park. The population grows at a

Amanda [17]

Answer:

FV= 200*(1.07^n)

Step-by-step explanation:

Current population= 200 deer

Growth rate= 7% per year

To calculate the future value of deer in any given years, we need to use the following formula:

FV= PV*(1+g)^n

FV= future value

PV= present value

g= growth rate

n= number of years

FV= 200*(1.07^n)

For example, the population in 5 years:

FV= 200*(1.07^5)

FV= 281
