Answer:
<h3>x = 1 and 2/3 or x = 1 2/3</h3><h3 />
Step-by-step explanation:
Simplify both sides of equation
1 * x = 1 2/3
1 * x is 1x which is the same as x because there is one x
then for the improper fraction which is 1 2/3
to simplify improper fractions we times the whole number by the denominator
so 1 * 3 then add the numerator 2 and the denominator stays the same so we get x = 5/3
now we have x = 5/3 this is not correct because the numerator is bigger than the denominator so we just subtract the denominator from the numerator and how many times 3 goes into 5 (in this case 1) becomes the new whole number.
therefore we get x = 1 2/3
Answer:
Relative minimum: 
, Relative maximum: 
Step-by-step explanation:
First, we obtain the First and Second Derivatives of the polynomic function:
First Derivative
(1)
Second Derivative
(2)
Now, we proceed with the First Derivative Test on (1):
The critical point is 
.
As the second derivative is a constant function, we know that critical point leads to a minimum by Second Derivative Test, since 
.
Lastly, we find the remaining component associated with the critical point by direct evaluation of the function:
There are relative maxima.
Answer: You need to find the radius...
Step-by-step explanation:
Answer:
I. L = 17 cm.
II. W = 11 cm.
Step-by-step explanation:
Let the length of the rectangle be L.
Let the width of the rectangle be W.
Given the following data;
Perimeter of rectangle = 56cm
Translating the word problem into an algebraic expression, we have;
L = W + 6 .....equation 1
The perimeter of a rectangle is given by the formula;
P = 2(L + W)
56 = 2(L + W) ......equation 2
Substituting eqn 1 into eqn 2, we have;
56 = 2(W + 6 + W)
56 = 2(6 + 2W)
Opening the bracket, we have;
56 = 12 + 4W
4W = 56 - 12
4W = 44
W = 44/4
W = 11 cm
Next, we would find the length of the rectangle;
From eqn 1;
L = W + 6
L = 11 + 6
L = 17 cm
