190-(50+80)t=0
190-130t=0
130t=190
t=19/13 so the trains will remain apart for 19/13 hours.
Since ironman is flying at a constant rate of 150mph he will fly:
150(19/13)≈219.23 miles in that time period while the trains are apart.
Answer:
B. 2x + y = pi + 1.
Step-by-step explanation:
y = sin x + 2 cos x
The slope of a line tangent is the derivative, so:
y' = cos x - 2 sin x
At (pi/2, 1) , substituting for x:-
cos pi/2 - 2 sin pi/2
= 0 - 2 * 1 = -2.
So the slope is - 2 and an equation can be found by using the point-slope formula:
y - y1 = m(x - x1) so:
y - 1 = -2(x - pi/2)
y = -2x + pi + 1
2x + y = pi + 1.
Do 42 divided by 15 then divided 12 by the awnser. And you do 42 divided by 28 and divided that by 12 I think I'm pretty sure
Answer:
Greatest number is 65432
Lowest number is 23456
Step-by-step explanation:

Answer:
A
Domain equals to x, and x is the number or equation you put into the function. So it's suppose to be A.
