Joelle walked for 20 minutes and her speed was 3 miles per hour.
So
In 1 hour or 60 minutes Joelle walked for a distance of = 3 miles
Then
In 20 minutes Joelle walked for = (3/60) * 20 miles
= 60/60 miles
= 1 mile
Again
Joelle ran for 15 minutes at a speed of 6 miles per hour
So
In 1 hour or 60 minutes Joelle walked for a distance of = 6 miles
so
In 15 minutes Joelle walked for a distance of = (6/60) * 15 miles
= 15/10 miles
= 3/2 miles
So
The total distance covered by Joelle = 1 + (3/2) miles
= (5/2) miles
= 2 1/2 miles
So Joelle covered a total distance of 2 1/2 miles while walking and running.<span />
1 1/4 because the 1 would be the 1 in 1 1/4 and .25 is 1/4 so.........
1 1/4
Answer:
steps below
Step-by-step explanation:
f(x) = 4√x - 2x ... x≥0
f'(x) = 2/√x - 2
critical points: x=0, x=1
x=1 y = 4√1 -2x1 = 2
extreme: (<u>1</u>,2) tangent line parallel to x axis: y = 2 .... <u>x = 1</u>
x = 0 (x≥0): (0,0) tangent line parallel to y axis: <u>x = 0</u>
Answer:
n= 12 m=5
Step-by-step explanation:
Because it is a parallelogram, the parallel sides are equal in length. So n = side length 12. n = 12
For the other one, m + 1 = 6
Be careful to solve for m, not m+1.
m=6-1
m=5
Answer:
Step-by-step explanation:
complete the square:
Take a quadratic equation : ax²+bx+c and turn it to
a(x+d)²+e
d=b/2a and e=c-b²/4a
y=x^2 - 14x + 48
a=1 , b=-14 , c=48
d=-14/2=-7
e= 48-14²/4
e= 48-49
e=-1
complete the square for y=x²-14x+48
y= (x-7)²-1
