Answer:
$52,500
Step-by-step explanation:
8% x 52,500= 4200.
Slope of function B
Summa 180°
180-90= 90°
90-62°= 28°
when h(t)=0
-4.9 t²+19.6t=0
4.9t(-t+4)=0
either t=0 or t=4
so domain is 0≤t≤4
for range
h(t)=-4.9t²+19.6t
=-4.9(t²-4t+4-4)
=-4.9(t-2)²+19.6
so range is 0≤h≤19.6
7
each way from 10 to 7 is 3 and 4 to 7 is 4
