A bridge is 10 m above a railroad track and at right angles to it. A train is running at the rate of 20 m/s passes under the center of the bridge at the same instant that a car running 15 m/s reaches that point. How rapidly are they separating 3 seconds later?
Answers
x = 20t, y = 15t, z = 10
let s be thedistance between them at time t,
s^2 = (20t)^2 + (15t)^2 + 10^2 = 625t^2 + 100
2s ds/dt = 1250t
ds/dt = 625t/s
when t = 3, s = √(625*9+100) = 75.6637
ds/dt = 625*3/75.6637 = 24.78 m/s
The time taken that should be rapidly are distinct 3 seconds later should be considered as 24.78 m/s.
Calculation of the time taken:Here the point should be considered directly under the center of the bridge as the origin
Here
x = 20t, y = 15t, z = 10
let us assume s be the distance between them at time t,
So it be like
[tex]s^2 = (20t)^2 + (15t)^2 + 10^2 = 625t^2 + 100[/tex]
2s ds/dt = 1250t
ds/dt = 625t/s
Now at the time when
t = 3,
[tex]s = \sqrt (625*9+100)[/tex] = 75.6637
So,
ds/dt = [tex]625*3/75.6637[/tex] = 24.78 m/s

Answer:
y= 20x +30
Step-by-step explanation:
y - intercept of the graph is 30
Slope of the graph is [tex]\frac{20}{1}[/tex]
Answer:
y = 20x + 30
Step-by-step explanation:
y=mx+b
b value = y-intercept, so you find where the line crosses the y-axis.
Find point at (0,30); b = 30
m value = rise/run (rise over run) (y/x)
find the next point that the graph intersects at and count add to it to find 30.
the closest point is at (-1,10)
go back to rise/run
30-10 = 20
0-(-1) = 1
20/1 =20 is your m value
plug m value and b value into equation to form your line.
y=20x+30

How can knowing the slope and y-intercept help you graph an equation?
Answers
Answer:
To graph the equation of a line, we plot at least two points whose coordinates satisfy the equation, and then connect the points with a line. We call these equations "linear" because the graph of these equations is a straight line.There are two important things that can help you graph an equation, slope and y-intercept.SlopeWe're familiar with the word "slope" as it relates to mountains. Skiers and snowboarders refer to "hitting the slopes." On the coordinate plane, the steepness, or slant, of a line is called the slope. Slope is the ratio of the change in the y-value over the change in the x-value. Carpenters and builders call this ratio the "rise over the run." Using any two points on a line, you can calculate its slope using this formula.The total cost, in dollars of a membership in a fitness center is given by the function c(m) = 30m +20, where m is the number of months a person is a member.

In y = mx+b, b is the y-value of the y-intercept.
Here, b = -5.
Note: the y-intercept is a POINT, not a value.
Step-by-step explanation:
Hey there!
Given equation is; y= 3x-5.
Comparing the equation with y= mx+b, where "b" is y-intercept. we get;
y-intercept= -5
Therefore, y-intercept of the equation is"-5".

what is the value of?
Answers
Answer:
70 degrees
Step-by-step explanation:
Since the angles of a triangle have to add up to 180 degrees, you know that the third angle of the triangle on the left would be 180 - 60 - 65 = 55 degrees. Then, since the angles on a straight line have to add up to 180 degrees you could find one of the two missing angles of the second triangle by doing
180 - 55 - 50 = 75.
Then, you have 2 out of the 3 angles of the triangle on the right and you can find the third, the ?, by doing 180 - 75 - 35 = 70 degrees

During a catered lunch, an average of 4 cups of tea are poured per minute. The lunch will last 2 hours. How many gallons of tea should the cateree bring if there are 16 cups in one gallon?
Answers
Answer:
30 gallons (that’s a lot of tea!)
Step-by-step explanation:
Hi there!
we know that there are 60 minutes in an hour, 120 in 2 hours.
If 4 cups are poured every minute, we multiply 4 by the number of minutes in 2 hours, 120.
now we have 480 cups. However, they asked for gallons. They already give how many cups are in a gallon, 16, so all we have to do is divide 480 by 16 to find the amount of gallons needed.
480/16 = 30 gallons!
I hope this helped!
Answer:
30 gallon
Step-by-step explanation:
first you count up how many minutes is in 1 hour mutilply it by 2 if 4 cups were poured every minute and there's 16 cups per gallon you take 120 being 2 hours in minutes take 120 multiply it by 4 bc that's how man cups are poured per minute and that 480 cups 480 cups divided my 16 which is how many cups is in a gallon and you get 30
