Answer:
Step-by-step explanation:
In order to find the notation of a number find the total number of 0's that the number has, and realize that all whole numbers have a invisible decimal point.
Exponent is positive to move the decimal point to the right four times
Hope this helps.
Cos(42)=x/17000
X=17000*cos(42)
X=17000*0.743
X==12,631
5)
= - i - 2 - 3i
= - 4i - 2
= - 2 (2i + 1)
7)
= - 4 [(2 -2i - i (8 - 4i)]
= - 4 (2 - 2i - 8i + 4i^2)
= - 4 (4i^2 - 10i + 2)
= (- 4) (2) (2i^2 - 5i + 1)
= - 8 (2i^2 - 5i + 1)
9)
= p^2 - 4p - 4p + 16
= p (p - 4) - 4 (p - 4)
= (p - 4) (p - 4)
= (p - 4) ^2
11)
= p^2 - 8p - 8p + 64
= b (b - 8) - 8 (b - 8)
= (b - 8) (b - 8)
= (b - 8)^2
