Answer:
The formula 
Step-by-step explanation:
<em><u>Explanation</u></em>
Given W = x² - 2 y z
2 y z = x² + W
Dividing '2z' on both sides , we get

⇒ 
|-3|+|7|=10. The distance of the 2 numbers is 10, next multiply 3/5 into 10 and you get 6. -3+6 is 3, so the point you will end up on is 3.
Answer:
(a-1) *(a^2 +a-1) (a+2)
Step-by-step explanation:
a^4+2a^3-a-2
Lets factor by grouping
a^4-a + 2a^3-2
Factor out an a from the first group and a 2 from the second group
a(a^3 -1) +2(a^3-1)
Factor out (a^3-1)
(a^3-1)(a+2)
We need to recognize that a^3-1 is the difference of cubes
(x^3-y^3) = (x-y) (x^2+xy+y^2)
Let x=a and y=1
(a-1) *(a^2 +a-1) (a+2)
Solution :
The test is distributed normally with mean of 72.8 and the standard deviation of 7.3
Finding numerical limits for the D grade.
D grade : Scores below the top 80% and above the bottom 10%.
Let the bottom limit for D grade be
and the top limit for D grade be
.
First find the bottom numerical limit for a D grade is :



..........(1)
From (1)


= 63.45
≈ 64
Now the top numerical limit for D grade :





..........(2)
From (2)


= 66.668
≈ 67
Therefore, the numerical limit for a D grade is 64 to 67.
Answer:
When it comes to investing, compound interest is better since it allows funds to grow at a faster rate than they would in an account with a simple interest rate.
