(A) The constraint in the profit is calculated by letting p be equal to zero first,
p = 200k - 500 = 0
k = 2.5
If the number of knives sold is less than 3, then there is no profit.
(B) As more knives are sold, the amount of profit becomes higher.
(C) Yes it is
P = 200k - 500
14000 = 200k - 500 ; k = 72.5
To be able to do so, at least 73 knives should be sold.
Answer:
5.57
Step-by-step explanation:
In order to find the are of a square you would use the equation <em>a²</em>. However, since you are finding the length of one side and its a square, you use the equation
. The area of this square is 31 sq in., so you would replace a with 31. The equation then becomes
<em>. </em>When out into a calculator, the answer is 5.567764... which rounded up to the nearest hundreth is 5.57.
Answer:
![7+\sqrt{x+3}](https://tex.z-dn.net/?f=7%2B%5Csqrt%7Bx%2B3%7D)
Step-by-step explanation:
The conjugate of a radical expression is obtained by changing the sign of the middle term.
The conjugate of
is simply ![a-\sqrt{b}](https://tex.z-dn.net/?f=a-%5Csqrt%7Bb%7D)
Therefore, to obtain the conjugate of the given expression we simply shall be changing the negative sign to positive;
The conjugate of
is simply;
![7+\sqrt{x+3}](https://tex.z-dn.net/?f=7%2B%5Csqrt%7Bx%2B3%7D)
Answer:
100
Step-by-step explanation:
cosB = 36/60 = 3/5
cosB = 60/x = 3/5 -> x = 100
