Answer:
y = (- 7/8)*x - 1.5
Step-by-step explanation:
One point is (-4,2) and the other one is (4,-5)
The first step is to find the slope.
m = (y2 - y1) / (x2 - x1)
- y2 = 2
- y1 = -5
- x2 = -4
- x1 = 4
Solution
<em><u>Find the slope</u></em>
m = (2 - - 5) / (-4 - 4)
m = (2 + 5) / (- 8)
m = 7 / - 8
So far what you have is y = (-7/8)x + b
Find the y intercept.
Use (4,-5)
y = (-7/8)x + b
x = 4
y = - 5
-5 = (-7/8) * 4 + b
-5 = -7/2 + b
-5 = - 3.5 + b Add 3.5 to both sides.
-5 + 3.5= - 3.5+ 3.5 + b
- 1.5 = b

1 foot = 12 inches
2 x 12 = 24 +3 = 27 inches
3 x 12 = 36 +5 = 41 inches
27*41 = 1107 square inches
1107 * 0.35 = $387.45
Answer:
The radius of cylinder is 14 inches
Step-by-step explanation:
Given that the volume of cylinder is 196π in² and the height is 1 in . The formula for it is V = πr²h. Then you can substitute the following value into the formula:
V = 196π
h = 1
196π = π × r² × 1
r² = 196π/π
r² = 196
r = 14 in
Hello,
f(x,y)=2(x²+y²)-25(x²-y²)=0(1)
@f/@x=2*2*(x²+y²)*2x-50x
@f/@y=2*2*(x²+y²)*2y-50y
dy/dx=-(@f/@x)/(@f/@y)=0
==> 2x*(4x²+4y²-25)=0
==>x=0 or x²+y²=25/4 (2)
As (1)==>2*25/4-25(x²-y²)=0
==> x²-y²=1/2 (3)
(2) and (3)=>2x²=27/4 ==>x²=27/8 and y²=23/8
==>x=-√(27/8) and (y=-√(23/8) or y=+√(23/8)
or x=√(27/8) and (y=-√(23/8) or y=+√(23/8)
There you go! lmk if you have questions
