Answer: 8 m/s
First let’s convert the time to seconds. There are 69 seconds in a minute so 1 minute and 40 seconds is 60 +40 second which totals to 100 seconds
Now to get the speed in meters per second we divide the total meters run by the total seconds
So the speed will be 800m/100s = 8m/s
Rory walked 2/4 of a mile more than Louise.
Answer:
y = (1/5)x² or y = x²/5
Step-by-step explanation:
We have the function f(x) = ax² and are given that the point (5,5) is on the parabola. We need to find 'a'. f(x) can be replaced with 'y', so we can rewrite the equation as...
y = ax²
We know that when x = 5, y = 5, so we have
5 = a(5²) now simplify...
5 = 25a
5/25 = a
1/5 = a, so our equation becomes
(1/5)x² or x²/5 (the expressions are equal)
X=$212
$262-$50=$212
HOPE ITS RIGHT!!
HOPE THIS HELPS!!!
Y+2x=4
To get the answer subtract the 2x from both sides making it y = -2x+4
the slope is -2 and the y-intercept is 4
