Two cruise ships leave port at the same time. Ship A sails north at a speed of 20 mph while Ship B sails east at a speed of 40 m

tiny-mole [99]

Answer:

a) D(t) = $20*\sqrt{5} * t$

b) 178.885 miles

Step-by-step explanation:

Ship A travels north at the rate of 20 mph.

Ship B travels east at the rate of 40 mph.

After t hours, Ship A is at a distance of 20t miles from the origin.

Similarly, Ship B is at a distance of 40t miles from the origin.

(a) Distance D(t) = $\sqrt{(20t)^{2}+(40t)^{2}}$

= $\sqrt{400*t^{2}+1600 * (t)^{2}}$

= $\sqrt{2000*t^{2}}$

= $20*\sqrt{5} * t$

(b) Distance between the two ships when t = 4,

= $20*\sqrt{5} * 4$

= $80*\sqrt{5}$ miles

= 80 * 2.236

= 178.885 miles

Two plans for reaching a goal are given below. Plan A: Save $450 over the next 8 weeks by working 9 hours per week at $7. 20 per

nalin [4]

Answer:

C, both plans will work for achieving the goal.

Step-by-step explanation:

For plan A, you must multiply 7.20 by 9, then multiply the product by 8. The answer is 526.4 This means that plan A will work, and more than the original goal will be saved up.

For plan B, you must multiply 6.50 by 15, then multiply the product by 6. The answer is 585. This is more than the original goal, so plan B would work as well.

This means that C is correct, because both plans will work for achieving the goal.
