Step-by-step explanation:
Answer:
She paid back $192 in interest
Step-by-step explanation:
A = P(1+r)^n
P = $1,200
r = 10.5% = 0.105
n = 18 months = 18/12 = 1.5 years
A = 1,200(1+0.105)^1.5 = 1,200(1.105)^1.5 = 1,200×1.16 = 1,392
Amount = $1,392
Principal = $1,200
Interest = amount - principal = $1,392 - $1,200 = $192
Answer:
20.4
96
Step-by-step explanation:
The value of 5x² - 11x + 18 is
5(2.4)²-11(2.4) +18 = 5(5.76) -26.4+18
= 28.8 -26.4+18 = 20.4 (when x = 2.4)
and 5(-3)² -11(-3) +18 = 45+33+18 = 96
(when x = -3)
Answer: Let F(x, y, z) = x 2y 3 i+x 3y 2 j+ 2zk and C the curve parameterized by x(t) = cost, y(t) = sin t, and z(t) = t 2π
Step-by-step explanation:
Answer:
3^(k+2) = 9m/ 26
Step-by-step explanation:
Let 3^k = y :
y×3^3-y = m
26y = m
26×3^k = m
3^(k+2) = m/26×3^2
Therefore 3^(k+2) = 9m/26
