Answer:
- 494
Step-by-step explanation:
Breaking down the summation into it;s component parts
= 4k -  k(k + 1) ← substitute k = 19
 k(k + 1) ← substitute k = 19
= (4 × 19 ) - 1.5 × (19 × 20)
= 76 - (1.5 × 380)
= 76 - 570
= 494

Answer:
in 13.95 years the senior class will have 100 students. 
Step-by-step explanation:
P(h) = p(0.92)^t (equation for exponential change)
P(h) - population of highschool (or senior class) = 100
p - staring amount = 320
t = time in years
100 = 320(0.92)^t
1/3.2 = .92^t (divide both sides by 320)
log(1/3.2, .92) = t (log base 0.92 of 1/3.2 equals t)
13.9497 = t
 
        
             
        
        
        
G(x) = (x-2)^3
move F(x) = x^2 to the right 2 units
answer
C. G(x) = (x-2)^3
