Answer:
2a) the # of terms are 11
2b) the term with x^3 is 262440x^3
Step-by-step explanation:
(x+3)^10 expansion: x^10+30x^9+405x^8+3240x^7+17010x^6+61236x^5+153090x^4+262440x^3+295245x^2+196830x+59049
Answer:
(8,90°)
Step-by-step explanation:
To get this answer, you multiply the r values together to get 2*4 = 8. At the same time, you add the theta angles to get 45° + 45° = 90°
The general rule is that if A = (r,theta) and B = (s,phi) then
A*B = (r*s,theta+phi)
where the point (s,phi) is a polar form point.
Answer:
yes all
Step-by-step explanation:
Answer:
$5400
$45
Step-by-step explanation:
Interest = principal x interest rate x time
principal = p
interest rate = 15%
time = 20/365 = 0.054795
Interest = 5445 - p
5445 - p = 0.15 x p x 0.054795
5445 - p = 0.008219p
Collect like terms and solve for p
p = $5400
Interest = 5445 - 5400 = $45
