Answers
Using a linear function, we have that:
A. The rate of change is of -12 feet per second.
B. The rate of change is constant.
C. The initial height is of 1210 feet.
D. The linear function is: h(t) = -12t + 1210.
What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.From the table, when x changes by 5 seconds, the height decreases by 60 feet, hence the slope is given by:
m = -60/5 = -12 feet per second.
Hence the function is:
h(t) = -12t + b.
When t = 5, h(t) = 1150, hence we use this to find the initial height.
h(t) = -12t + b.
1150 = -12(5) + b.
b = 1210.
Hence the linear function is:
h(t) = -12t + 1210.

A freight train was supposed to travel 1300 miles in 50 hours. When the train had traveled 0.4 of this distance, it was delayed by 4 hours. What should the new speed of the train be to arrive on time?HELLPASAP
Answers
Answer:
The answer is 30 miles per hour
Step-by-step explanation:
1) From the question we can calculate the initial speed of the train
Initial speed = 1300 miles / 50 hours
= 26 miles / hour
2) Next, we can calculate the amount of distance already traveled:
Distance traveled = 1300 * 0.4
= 520 miles
3) Now let's calculate the amount of time it took to travel the 520 miles:
From point no. 1 we saw that it was traveling at the speed of 26 miles/ hour, so let's calculate the time elapsed.
Time elapsed = 520 miles / 26 hours
= 20 hours
But then again the text states the train was delayed by 4 hours, therefore the total time elapsed was 24 hours
4) Now to find the new speed required to arrive on time, we need to calculate how many hours and distance are left:
From point no. 2 we calculate the distance left
Distance left = 1300 - 520
= 780 miles
From point no. 3 we can calculate the amount of time left:
Time left = 50 - 24
= 26 hours
Finally, we can find the new speed required to arrive on time:
New speed = 780 miles / 26 hours
= 30 miles / hour

hours, and earned a total of $690.
How long did Giselle work as a
carpenter last week, and how long did
she work as a blacksmith?
Giselle worked as a carpenter for
hours and as a blacksmith for
hours last week.
Answers
Answer:
12 hours as a carpenter and 18 as a blacksmith.
Step-by-step explanation:
So she earns 20$ per hour as a carpenter. c can represent the amount of hours she worked as a carpenter, and the coefficient will be 20 (salary)
So she earns 25$ per hour as a blacksmith, b can represent the amount of hours she worked as a blacksmith, and 25 will be the coefficient (salary)
So we have the two equations:
c + b = 30
20c + 25b = 690
Now we can solve for c in terms of b and substitute that into the second equation:
Original equation:
c + b = 30
Subtract b from both sides
c = -b + 30
Original equation:
20c + 25b = 690
Substitute -b + 30 as c
20(-b + 30) + 25b = 690
Distribute the 20
-20b + 600 + 25b = 690
Simplify the equation
600 + 5b = 690
Subtract 600 from both sides
5b = 90
Divide both sides by 5
b = 18
Now plug this into either of the original equations to solve for c, but the first equation b + c = 30 is the easiest, so I'll use that equation
Original equation
b + c = 30
Substitute 18 as b
18 + c = 30
Subtract 18 from both sides
12 = c
