Answer:
Step-by-step explanation:
it is an adjacent/linear pair
X^2/a^2+y^2/b^2=1
or
x^2/900 + y^2/169 = 1 x^2/1467^2 + y^2/736^2= 1 x^2/736^2 + y^2/1467 = 1 x^2/169 + y^2/900 = 1
Answer:
1) 140 2)68 3) 125 4) 140
Step-by-step explanation:
for these, because you're trying to find the angle from 180 degrees, you would subtract the angle on the 180 degree line from 180.
1) 180-40 = 140
2) 180-112 = 68
3) 180-55 = 125
4) 180-40 = 140
Hope this helps!
Answer:
If you draw this out, you can see that total fence equation will be:
2L + 4W = 1200
Simplify, divide by 2
L + 2W = 600
L = (600-2W)
:
Area;
A = L*W
Substitute (600-2W) for L:
A = (600-2W)*W
A = -2W^2 + 600W; a quadratic equation
:
The dimension that will produce the greatest area will be the "axis of symmetry
which is: x = %28-b%29%2F%282a%29
:
In this equation a=-2, b=600
W = %28-600%29%2F%282%2A-2%29
W = %28-600%29%2F%28-4%29
W = +150 ft is the width
:
Find the length
L = 600 - 2(150)
L = 300 ft is the length
:
We can say the a field 300 by 150 gives he greatest area
:
This illustrated on a graph where y axis is the area and x axis is the width:
Step-by-step explanation:
Y=-3/2L -2. At the Y axis, line L is at -2, so we add that as B or the Y intercept. We can see that the graph goes 2 over to the right and down three, which makes the slope negative and 3/2 (rise/run)
