Answer:
The dimensions are 9m by 18 m
Step-by-step explanation:
The perimeter will be
x+y+x for the three sides ( the wall is the fourth side)
2x+y = 36
Solving for y
y = 36-2x
The area is x*y and we want it maxed
A =x( 36-2x)
36x-2x^2
Taking the derivative
dA /dx = 36 - 2 * 2x
Setting this equal to zero to find the max
0 = 36 - 4x
4x = 36
Divide by 4
x = 36/4
x = 9
Now find y
y = 36-2x
y = 36 - 2*9
y = 36 - 18
= 18
The dimensions are 9m by 18 m
Answer:
you find the x and y intersepts and draw the line
Step-by-step explanation:
if we break down the equasion in the end it's y=x+4 and from there we can find the intersepts by canceling out, y=x+4 becomes y=4 and 0=x+4 wich is x=-4
Answer:
I believe the answer is B
Step-by-step explanation:
The answer is b, because it is linear and x and y have a proportional relationship with x increasing by 2 and y increasing by 4. So the slope is 2/4 or 1/2 making it a proportional relationship.
Answer:
Well. it depends on how many songs... so
Step-by-step explanation:
1 x 2.5. 2.5. 2 x 2.5. 3 x 2.5. 7.5. 4 x 2.5. 5 x 2.5. 12.5. 6 x 2.5. 7 x 2.5. 17.5. 8
This could be wrong but..
Find the negatice reciprocal of the slope of the origial line and use the slope-intercept form y=mx+b to find the line perpendicular to x=4
Y=2
Sorry if this is wrong :/
