Find the range of y = 3cos4x - 2. 1 ≤ y ≤ 3 -3 ≤ y ≤ 3 -5 ≤ y ≤ 1 -5 ≤ y ≤ 5

change of stock price/initial stock price on friday * total stock value = change of stock value

0.89/73.73 *x = 42.72

x=3539.04 = total stock value at initial stock price on friday .

total stock value at initial stock price on friday/ initial stock price on friday = number of shares

3539.04/73.73 = 48 shares

they own 48 shares of this stock

the answer is d

step-by-step explanation:

you can also use mathway to get you answer + steps

f(x) is   are being squared

g(x) is   increasing by 2

h(x) is adding .25 each time

k(x) is taking the square root

f(x) and k(x) are exponential functions

you have 6 equal triangles, find the area of one of them (b*h/2) and multiply by 6

(8*4: 2)*6 =

32 cm² is your answer
