Taking commen 2 in RHS
p = 2 (L+W )
Divide by 2 on both sides.
p/2 = L+W
Subtract W on both sides.
p/2 - W = L
or L = p/2- W

Let f(x)=x^2-2x+1
1 answer:
Answer:
a.) f'(x) = 2x - 2
b.) horizontal tangent line at (1, 0)
c.) view image
d.) the point given, (-1, -1/2), isn't even located on the graph of f(x). Either there is a typo or the question is poorly stated.
Step-by-step explanation:
a.) You should know how to do derivative already
b.) Horizontal tangent line just mean that the slope is zero. Since a derivative is a slope, just find when the derivative is equal to 0.
c.) The function f(x) looks like a U. The only spot that has a zero slope is at the bottom of the U when the slope changes from negative to positive. Since my horizontal tangent line(where the slope is 0) is located at point (1,0), that must be where the bottom of the graph is,
d.) Poorly stated question. The point given isn't even located on the graph.

Answer:
y = 60
Step-by-step explanation:
<h3>Step 1: Make sense of the given</h3>"The ratio of y to x is 3"
This means that,
"The sum of y and x is 80"
This means,
If , then
.
We can plug this into the other equation by substitution:
This simplifies to:
Which we can solve out and get:.
We solved for x, but we need the value of y.
So, we go back to the equation we first derived: "".
And now we substitute the value of x, into this.
By solving this out, we get:
So, the value of y is 60.
Answer:
4+3=3+4
Step-by-step explanation:
The commutative property of addition says that, the order in which you add two real numbers does not matter.
Let , then
a+b=b+a
From the given options;
4+3=3+4
shows the commutative property of addition
