Money that is collecting interest in a bank account doubles in value every 10 years.
When the account was opened, it had 16, or 2 to the power of 4, dollars in it. After 50 years, the account balance has doubled 5 times, increasing by a factor of 2 to the 5th power.
It now has a balance of 2 to the 4th power x 2 to the 5th power. Expressed as a power, how much money, in dollars, is in the account after 50 years?

A. 4 to the power of 9
B. 2 to the power of 20
C. 2 to the power of 9
D. 2 to the power of 5

y-1700=200(x+4)

step-by-step explanation:

200(x+4) is 200x + 800 she is saving 200 per week x is the weeks and the -1700 is. us that’s howmuch she already had

connie < felicia < stew

step-by-step explanation:

stew:

we need to find the slope

m = (y2-y1)/ (x2-x1)

    = (2650-795)/(10-3)

    = 1855/7

connie:

we need to find the slope

m = (y2-y1)/ (x2-x1)

we have two points (0,0) and (4,800)

m = (800-0)/(4-0)

  m = 800/4

felicia:

260 words per minute

200< 260 < 265

connie < felicia < stew

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47

where is the figure
