1) 0.5m . 2 = 1 meter
2) 4.70$
3) (r^2) / 2 = 81/2 = 40.5m^2
Answer:
Since
4
4x
and
4
n
have the same denominator, add them by adding their numerators.
Step-by-step explanation:
Answer:
-7 meters
Step-by-step explanation:
-15 after diving down
-15+8 because 8 meters up
-15+8=7
The given equations are y= 6x^2+1 and y=x^2+4
Both the equations equal y so we can make them equal
6x^2+1=x^2+4
To bring x term on one side we subtract x^2 both sides
6x^2-x^2+1=4
5x^2+1=4
To isolate x term we subtract 1 both sides
5x^2=4-1
5x^2=3
Dividing by 5 both sides
X^2=3/5
Taking root of both sides we have:
X=±√⅗
Substituting x value to find y
When x=+√⅗=0.7745
Y= 6x^2+1
Y=6(3/5)+1
Y= 18/5+1
Y=23/5 =4.6
When x= -√⅗=-0.7745
Y= 6(3/5)+1
Y=23/5=4.6
Point of intersections are ( 0.7745,4.6) and (-0.7745,4.6)

Notice that equality holds when either

or

, so these should be included in the solution set.
Now, since the coefficient of the leading term is positive, we know the parabola opens upward, which means we know that

when

and

, and that

when

.
So the solution set is the interval

.
