Answer:
≥≤ are used when the number is less/greater or equal than some thing.
>< are used when a number is strictly less/greater than some thing.
1) a number x is less than 0 or at least 3
A number x is less than 0 is written as: x < 0.
x is at least 3 is written as: x ≥ 3.
Then we can write the statement as:
x < 0 ∨ x ≥ 3.
where ∨ means "or"
2) a number x is less than or equal to 4 and greater than -1
x less than or equal to 4 is written as: x ≤ 4
x is greater than -1 is written as: x > - 1.
We can write the statement as:
-1 < x ≤ 4
3) a number x is less than 8 and greater than or equal to 5
x is less than 8 is written as: x < 8
x is greater than or equal to 5 is written as: x ≥ 5.
Then the statement can be written as:
5 ≤ x < 8,
Well, there's really no such thing as the "distance between integers",
because numbers are not physical things that you can set on a table.
One way of representing integers is to draw a picture of a "number line",
and put marks at the positions of the integers. When you do that, the
difference between two integers and the distance between their marks
on the number line are exactly the same.
Answer:
Answer:
$8,706
Step-by-step explanation:
Lionnel is considering doing some long term investments with the money she inherited
She would like to have $50,000 at the end of 30 years
The interest is 6%
Therefore the amount that Lionnel would need to put into the account can be calculated as follows
A= P(1+r)^t
50,000 = P(1+6/100)^30
50,000 = P (1+0.06)^30
50,000 = P(1.06)^30
50,000= 5.7434P
P = 50,000/5.7434
P= $8,706
Hence Lionnel will need to put $8,706 into an account earning 6% interest
Step-by-step explanation:
Probability of rolling an odd number is 3/6
(f-g)(x)= f(x)-g(x)
(f-g)(x)= x⁴-x²+9-(x³+3x²+12)
(f-g)(x)= x⁴-x²+9-x³-3x²+12
(f-g)(x)=x⁴-x³-4x²+21
