Answer:
50.2 in^2
Step-by-step explanation:
Using the Formula
A=πr2
d=2r
Solving for A
A= 1/4 π d^2 = 1/4*π*8^2 = 50.26548
=50.2in^2
Answer:
5%
Step-by-step explanation:
Divide the commission by the selling price of the car:
$500
------------- = 0.05.

This 0.05 translates into 5%. That's the commission rate.
Answer:
The table is a quadratic function
Step-by-step explanation:
Given
The attached table
Required
Tell if it is a quadratic function
The difference in the x values are uniform (i.e. difference of 1), so the following method can be applied.
(1) Subtract adjacent y values.




(2) Subtract adjacent differences in (1) above



Notice the calculated differences in (2) are the same.
<em>Hence, the table is a quadratic function</em>
Answer:

Step-by-step explanation:




The imaginary unit, i, which represents the square root of -1 raised to power 4 is 1
The organized steps are;
- Choice F; Therefore, Sebastian is incorrect
Reason:
The given expression Sebastian simplified is; -4·i²¹²
The result Sebastian got = 4
The organized steps are presented as follows;
We have that 212 ÷ 4 = 3
Since i⁴ = 1
Then -4·1 = -4
Therefore, Sebastian is incorrect
The order of the steps are therefore;
Given -4·i²¹²
Choice E; Since i⁴ = 1
Choice B; Then -4·1 = -4
Choice F; Therefore, Sebastian is incorrect
