(those are the answers i got i'm sorry if some of them are not correct but i used a website called mathpapa and its an algebra calculator and works well)
Answer:
0.73 yrs
Step-by-step explanation:
if t is time in years
quarterly
600 = 200(1 + 0.06625/4)^4t
3 = (1 + 0.06625/4)^4t
ln3 = 4tln(1. + 06625/4)
t = ln3 / (4ln1.0165625)
t = 16.7198 yrs
continuously
600 = 200e^(0.06875t)
3 = e^(0.06875t)
ln3 = 0.06875t
t = ln3 / 0.06875
t = 15.9798 years
Δt = 16.7198 - 15.9798 = 0.73 yrs
Discriminant b^2-4ac = (-9)^2 - 4*2*9 = 9
so there are 2 roots
because of the -9x and 9 they will both be positive
Answer:
95 ft²
Step-by-step explanation:
Given:
regular pyramid with,
Square base of side length (s) = 5 ft
Slant height (l) = 7 ft
Required:
Surface area
Solution:
Surface area of a regular pyramid = ½*P*l + B
Where,
P = perimeter of the square base = 4(s) = 4(5) = 20 ft
l = slant height = 7 ft
B = area of base = s² = 5² = 25 ft²
Surface area = ½*20*7 + 25
= 10*7 + 25
= 70 + 25
Surface area of regular pyramid = 95 ft²
