Working together they would fill two pools in 120 minutes so therefore they would fill one pool in 60 minutes
Answer:
y=x-5
Step-by-step explanation:
slope of line s=-1= m1
lines are perpendicular m1m2=-1 m2=1
equations of t=y-y1=m2(x-x1)
y-2=x+3
y=x+5
75 mi. East, 70 mi. South, 110 mi.West.
Overall, she drove 110-75= 35 mi. West since east & west are opposite directions.
And 70 mi. South.
In a Pythagorean theorem problem, legs are 35 & 70. And hypotenuse is her diagonal distance from where she started
35^2 + 70^2 = c^2
1225 + 4900 = c^2
6125 = c^2
78.3=c
Answer:
13.5 m/s
Step-by-step explanation:
To start off, simply plug in the values into the equation. This is shown below...
<u>v = velocity</u>
<u>u = initial velocity</u>
<u>a = acceleration</u>
<u>t = time</u>
v = u + at ---> v = 3 + 1.5(7)
First, multiply 1.5 and 7 together. By doing so, you get 10.5. Now the equation is...
v = 3 + 10.5
To finish, simply add 3 and 10.5...
v = 3 + 10.5 ---> v = 13.5
<u>Your answer is 13.5 m/s</u>
If you take the derivative of your equation, you get:

or

Let =′
v
=

and we have ′(2−)=0,
v

=

,
so either ′=0
v

and =

v

.
Then ′=

Plugging the first into the original equation gives =−2
