Answer:
Let's solve for c.
cx=50
Step 1: Divide both sides by x.
cx
x
=
50
x
c=

Answer:
21.09 ft/s
Step-by-step explanation:
The first step is to create the ratio of speed/time.
Next we must simplify
Next we must convert 14 miles in to feet. There are 5280 feet in a mile.
14 * 5280ft = <u>75,920 feet</u>
Now for hours into seconds.
1 hour = 60 min, 60 min = 3600 seconds
Our new ratio is \frac{75920ft}{3600sec}
simplify.
75920ft / 3600sec = 21.09ft/s
Answer:
6
Step-by-step explanation:
length times weight
but you don't know what the length is so devid 24 to 4
24 devid 4 = 6 and there you go
and to check it 4x6=24
so yeah...
L=4*w-15
P=2w+2l=2w+2*(4w-15)=2w+8w-2*15=400
10w-30=400
10w=400+30=430
w=430:10
w=43 m
l=4*43-15=172-15
l=157 m
Let A( t , f( t ) ) be the point(s) at which the graph of the function has a horizontal tangent => f ' ( t ) = 0.
But, f ' ( x ) = [ ( x^2 ) ' * ( x - 1 ) - ( x^2 ) * ( x - 1 )' ] / ( x - 1 )^2 =>
f ' ( x ) = [ 2x( x - 1 ) - ( x^2 ) * 1 ] / ( x - 1 )^2 => f ' ( x ) = ( x^2 - 2x ) / ( x - 1 )^2;
f ' ( t ) = 0 <=> t^2 - 2t = 0 <=> t * ( t - 2 ) = 0 <=> t = 0 or t = 2 => f ( 0 ) = 0; f ( 2 ) = 4 => A 1 ( 0 , 0 ) and A 2 ( 2 , 4 ).
