Perpendicular slopes multiply to -1, so are <em>negative reciprocals.</em>
-1 / -3 = 1/3
Answer: B. 1/3
Answer:
<em><u>[</u></em><em><u>2</u></em><em><u>,</u></em><em><u>4</u></em><em><u>,</u></em><em><u>6</u></em><em><u>]</u></em>
Step-by-step explanation:
GIVEN EQUATION : 2X+3≥7
i.e, 2x≥7-3
i.e, 2x≥4
i.e, x≥4/2
i.e, x≥2
it's represent number should be greater than or equal to 2
The only number which follows the inequality from the set is 2,4&6
✌️:)
Yay, derivitives
I'mma ignore that x is the shorter side because I don't know which one has to be shorter yet
we need to find the max area
but with 3 sides
area=LW
let's say the sides are z and y
zy=area
and the relatiionship between them is
hmm,
z+2y=1200
because one side has no fencing
so
z+2y=1200
solve for z
z=1200-2y
sub for z in other
(1200-2y)(y)=area
expand
1200y-2y²=area
take derivitive
1200-4y=dy/dx area
max is where dy/dx goes from positive to negative
solve for where dy/dx=0
1200-4y=0
1200=4y
300=y
at y<300, dy/dx<0
at y>300, dy/dx>0
so at y=300, that is the max
then
z=1200-2y
z=1200-2(300)
z=1200-600
z=600
so then
z=600
y=300
300<600
so the shorter side would be y
so then we see our choices and noticed that
erm
I think it is f(x)=1200x-2x²
takind the derivitive yeilds none of the others
so ya, you are right
Answer:
Your answer would be x = 1/2
Step-by-step explanation:
1/x = 2
You would divide x on both sides...then they would cancel each other out.
But now you're left with...
1 = x•2
So, re-order the terms so constants are on the left
1 = 2x
Divide 2 on both sides...
Now you're left with
1/2=x or more practically it would be x = 1/2
Hope this helps!
