Answer: there are 200 nickels in 1 kilogram of nickels
Step-by-step explanation:
For this case we must take into account the following conversion:
1Kg = 1000 g
Therefore, we can make the following rule of three:
5 grams ---------> 1 nickel
1000 grams ----> x
Clearing x we have:
x = (1000/5) * (1)
x = 200 nickels
Part (a)
Plug in y = 0 and solve for x. Use the zero product property
y = x(x+3)(x-2)
0 = x(x+3)(x-2)
x(x+3)(x-2) = 0
x = 0 or x+3 = 0 or x-2 = 0 .... zero product property
x = 0 or x = -3 or x = 2
The three roots or zeros are x = 0 or x = -3 or x = 2
================================================
Part (b)
The roots of the graph are: x = -2, x = 1, x = 3. Each root is where the graph crosses or touches the horizontal x axis.
Note how x = 0 is found in part (a), but not found here. This is one example where the graphs don't match. Another would be x = -3 is in part (a), but not here.
So that's why the graph does <u>not</u> match with the function in part (a)
Answer:
2.5
Step-by-step explanation:
1: -27/45. 2 : -1/2 hope this helps
The number of ways by which exactly 2 people are taller than the person behind them is; 6.
<h3>What number of ways can they line so that exactly two people are taller than the person behind them?</h3>
It follows from content that since 4 individuals with different heights are to line up, the 2 individuals who must be taller than the person behind them are represented as one entity and must be in the 1st and 2nd position or the 2nd and 3rd position.
Hence, the number of ways is; 6 upon counting the number of possible outcomes.
