Answer: p=30d


Step-by-step explanation:

Given: The number of pounds p of fish that a dolphin eats in d days.

Since, A dolphin eats 30 pounds of fish per day.

Then the total number of pounds fish eaten by dolphin=30 times number of days.

Thus, p=30\times d\\\Rightarrow\ p=30d

To plot graph, we need to find to points that lie on the graph of function.

At d=0, p=0

At d=1, p=30

Then we have points = (0,0) and (1,30), draw a line from it.

A ship travels 200 miles due west, then adjusts its course 30° north of west. The ship continues on this course for 30 miles. Ap
Marta_Voda [28]

Answer:

174.66\ mi  or 175\ mi

Step-by-step explanation:

we know that

Applying the law of cosines

c^{2}=a^{2}+b^{2}-2(a)(b)cos(C)

In this problem we have

a=200\ mi

b=30\ mi

C=30\°

substitute the values

c^{2}=200^{2}+30^{2}-2(200)(30)cos(30\°)

c^{2}=30,507.695

c=174.66\ mi

ElenaW [278]

The total amount of money Ethan made in a week including commission is $812.5

<h3>Total income</h3>

  • Total sales for the week = $1250
  • Base salary = $500
  • Percentage commission = 25%

Amount of commission earned = 25% of $1250

= 25/100 × $1,250

= 0.25 × 1250

= $312.5

Total earnings = Base salary + Amount of commission earned

= $500 + $312.5

= $812.5
