The answer is (-5,2) (if i am wrong, sorry i am rusty)
<span>h(t) = 210 – 15t models the altitude of a hot air balloon over time t, in minutes
means that at time t min, the height h of the balloon is 210-15t (units)
for example,
at time t=1 min, the height of the balloon is 210-15*1=195 (units)
at time t=2 min, the height of the balloon is 210-15*2=210-30=180 (units)
Thus, h(10) is the height of the balloon at time t=10 min,
h(10)=210-15*10=210-150=60</span>
Answer:
