X value is -1. y value is 21
(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.
By definition we have the meaning of FOIL is given by:
F: First
O: Outer
I: Inner
L: Last
We have then the following product:
Applying the FOIL method we have that the products are given by:
Answer:
the answer choice showing the FOIL method products is:
B. (X) (4x) + (2) (x) + (- 3) (4x) + (- 3) (2)
Option D, 63 cm
Explanation:
The scale of model is of local park is
This means that each dimension of the model is 21 times smaller than the actual park (to be developed in future)
Given -
Depth of the pond centi meter
Depth of the real pond will be 21 times of the depth of the model.
Thus , real pond's depth is equal to
cm
Hence, option D is correct
