Answer:
168.4953 (m/s)
Step-by-step explanation:
a(t)=x''(t)=(0.0951t⁴-0.101t³+0.837t²+3.87t-9.37)''= =4*3*0.951t²-3*2*0.101t+2*0.837 =11.412t²-0.606t+1.674.
a(3.85)=11.412*3.85²-0.606*3.85+1.674=168.4953
At the first store, Julia spent 50 dollars. Since 20 percent is 100 divided by 5, you multiply the 10 dollars by 5 to get 50 dollars.
At the second store, Julia spent. Since 12 dollars is 20 percent, multiply 12 dollars by 5 to get 60 dollars.
50+60= 110. Julia spent 110 dollars altogether.<span />
