Y^2=x+2
here vertex = (-2,0)
+ AOS =0
Also Y= (x+2)^2
Vertex = -2,0
AOS = x+2 =0
<span>so, in total 4 parabolas are possible with the information provided</span>
Answer:
=2 =−2
Step-by-step explanation:
<em>Common factor</em>
16 2 − 64 = 0
16(2 − 4)= 0
Use the sum-product pattern
16(2−4)=0
16(2 + 2 − 2 − 4) = 0
Common factor from the two pairs
16(( 2 + 2) + (−2 − 4)) = 0
16 ( ( + 2 ) − 2 ( + 2 ) ) = 0
Rewrite in factored form
16 ( ( + 2 ) − 2 ( + 2 ) ) = 0
1 6 ( − 2 ) ( + 2 ) = 0
Create separate equations
16 ( − 2 ) ( + 2 ) = 0
− 2 = 0
+ 2 = 0
Solve / Rearrange and isolate the variable to find each solution
= − 2
= 2
Answer:
shawty i think we need more info to solve this-
Step-by-step explanation:
There is a 3 hour difference in travel time.
So if x is the speed of the freight train and distance is 240 miles...
3(3x)-3x=240
9x-3x=240
6x=240
x=240/6
x= 40mph for the freight train..
passenger train is 3 times faster than the freight..
3×40=120mph
The surface area for this case is given by:
A = 2 * pi * r ^ 2 + 2 * pi * r * h
Where,
r: radius of the coins
h: height of the coin stack.
Substituting values we have:
A = 2 * 3.14 * (1/2) ^ 2 + 2 * 3.14 * (1/2) * (100 * (1/8))
A = 40.82 in ^ 2
Note: the correct thickness of the coins should be 1/8 in.
Answer:
Jose will need 40.82 in ^ 2 to cover the stack of coins
