Answer:
The initial value of the function is 25 and the rate of change is - 5.
Step-by-step explanation:
The table gives the ordered pairs of linear relation and they are (1,20) and (3,10).
Now, the equation of the linear relation that includes those ordered pairs will be
⇒ y - 10 = - 5(x - 3)
⇒ y - 10 = - 5x + 15
⇒ y = - 5x + 25
Therefore, the initial value of the function is 25 and the rate of change is - 5. (Answer)
1. The total distance will be equal to 20 miles plus the remaining distance which would be obtained when you multiply the speed to time t. The equation would be written as follows:
<em>120 = 20 + 50t</em>
2. The minimum time would be 0 hours. The maximum time is when the total distance of 120 is fully covered.
t ≤ (120 - 20)/50
t ≤ 2 hours
<em>Thus, the domain would be 0 < t ≤ 2.</em>
the answer would be a I'm my mind
Answer:d. W=20m
Step-by-step explanation:
w=20(1), 1 minute is 20 words
W=20(2) 2 minutes is 40 words
W=20(3) 3 minutes is 60 words

Step-by-step explanation:</u></h2><h3>
Over all plan: </h3>
This is a square pyramid so you know that all four triangular sides are congruent. This means that to solve this problem, which is asking you to find the surface area, you need to find the area of one of these triangles, and multiply that by 4. Next you need to find the area of the square and add it to the areas of the triangles.
Detailed Steps:
- You know the formula to finding the area of the triangle is
where b is the base length and h is the height. We are given b = 6 and h = 7 in your question.
- <u>Plug in the values into the formula.</u> You get:
- <u>Simplify.</u> You get:
- Next Multiply this by 4 to find out the total area of all the triangular faces.
- 21 x 4 = 84
- Now find the area of the square.
- The formula for the area of a square is
where s is the given value of a side.
Plug in your value, 
36+84=120.
120 is your final answer.
hope this helped
peace ✌
