(72÷2)³ - 7 · 9 ÷ 9
First, parenthesis
72÷2 is 36
Next, exponents.
36³ is 46656.
Then, multiplication.
7 · 9= 63
After that, division.
63 ÷ 9 is 7
Finally, subtraction.
46656 - 7 is 46649
Answer:
4.8
Step-by-step explanation:
Find rates of change until you find a constant.
dy/dx=1,2,3,4,5,6
d2y/dx2=1,1,1,1,1
So the acceleration, d2y/d2x, is constant. This means that this is a quadratic sequence of the form a(n)=an^2+bn+c. So we can set up a system of equations to solve for the values of a,b, and c. Using the first three points, (1,1), (2,2), and (3,4) we have:
9a+3b+c=4, 4a+2b+c=2, and a+b+c=1 getting the differences...
5a+b=2 and 3a+b=1 and getting this difference...
2a=1, so a=1/2 making 5a+b=2 become:
2.5+b=2, so b=-1/2, making a+b+c=1 become:
1/2-1/2+c=1, so c=1 so the rule is:
a(n)=0.5x^2-0.5x+1 or if you prefer to not have decimals
a(n)=(x^2-x+2)/2
Answer:
C. The meeting will be in Los Angeles California on July, 17.
Step-by-step explanation:
This doesn't use commas correctly because there should be a comma after Los Angeles because it is a location. Also, there should not be a comma after 17 because the comma goes after the date when the year is included, which it is not.
Answer: D. y = x^2
Step-by-step explanation:
Linear functions are functions in which the power of the unknown variable is 1 , that is the other of the unknown variable will be 1
A. y = x
This is a linear function because both x and y has 1 has their power
B. y = 2x
This is also linear
C. y = x + 2
This is also linear
D. y = x^2
This is not linear , although the power of y is 1 but the power of x is 2 , for it to be linear , the highest power of the unknown must be 1
