Answer:
w^2 + 13w + 39
Step-by-step explanation:
Multiplying Polynomials (FOIL- Firsts, Outs, Inners, Lasts)
(w+9) (w+4) Multiply- Firsts (w*w) Outs (w*4) Inners (9*w) Lasts (9*4)
w*w + w*4 + 9*w + 9*4 Multiply the FOIL
w^2 + 4w + 9w + 36 Combine like terms (same variables, numbers)
w^2 + 13w + 39
B- use Desmos it helps a lot!
Answer:
D) -1.8, -1 1/2 , 0.3 , 3/4 , 1
Step-by-step explanation:
Change all of the given terms to either fractions or decimals. Generally decimals are easier:
3/4 = 0.75
-1.8 = -1.8
1 = 1.0
-1 1/2 = -1.5
0.3 = 0.3
Order from least to greatest:
-1.8 , -1.5, 0.3 , 0.75 , 1.0
or
-1.8, -1 1/2 , 0.3 , 3/4 , 1

Answer:
6.66%
Step-by-step explanation:
((1 + r/m)^n) - 1
Interest rate , r = 6.5%
m = number of compounding times per period = 4 (quarterly interest)
((1 + 0.065/4)^4) - 1
((1 + 0.01625) ^4) - 1
((1.01625)^4) - 1
1.06660 - 1
= 0.0666
0.0666 * 100%
= 6.66%
