Answer: D) (x+1)(x + 2)(x-3)
This is because the roots are x = -1, x = -2 and x = 3
Simply get all the numbers to each side to have 0 on the right side
x = -1 turns into x+1 = 0
x = -2 turns into x+2 = 0
x = 3 turns into x-3 = 0
The three factors are (x+1), (x+2) and (x-3)
Which leads to (x+1)(x+2)(x-3)
Answer:
B
Step-by-step explanation:
In this case you would use the pythagoram theorem.
A^2+B^2=C^2
8^2+B^2=10^2
64+B^2=100
subtract 64
B^2=36
square root both sides
B=6
Answer:
I can't give an answer directly due to no chart.
Step-by-step explanation: Switch spoons and forks from the graph and then plot the points going left or right (depending on whether the number is positive or negative) Then go up or down (depending on whether the number is positive or negative).
Answer:
The person must leave the money for 11.8 years until the investment reaches 1600 dollars.
Step-by-step explanation:
Given that a person invests 1000 dollars in a bank, and the bank pays 4% interest compounded quarterly, to determine to the nearest tenth of a year, how long must the person leave the money in the bank until it reaches 1600 dollars the following calculation must be done:
1000 x (1 + 0.04 / 4) ^ Xx4 = 1600
1000 x 1.01 ^ 4X = 1600
1010 ^ 4X = 1600
X = 11.8
Therefore, the person must leave the money for 11.8 years until the investment reaches 1600 dollars.
