2.)suppose a population of 160 crickets doubles in size every month. the function f(x)=160*2^x
2,684,354,560 crickets
640 crickets
7.680 crickets
655,360 crickets
3.) suppose an investment of $2,300 doubles in value every decade. the function f(x)=2,300*2^x gives the value of the investment after x decades. how much is the investment worth after 2 decades ?
$2,355,200
$92,000
$46,000
$9,200

1. It is Given that

Population of 160 crickets doubles in size every month.

The function f(x)=

Population after a month= = 160 ×2= 320

Population after 2 month =  = 160 ×4= 640

(c)→Invalid number, because number of months is a natural number.

(d)

months

(a)  

Does not give value of x ,a natural number, as x is number representing number of months.

(2) The function which gives investment after x decades

1 decade= 10 years

2 decade = 20 years

 = 2300 ×4= $ 9200

for the points

step-by-step explanation:

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x
