Answer: $49.4
Step-by-step explanation:
Simple interest is calculated thus:
Principal × Rate × Time
Principal= $380
Rate= 13%= 13/100=
Time= 1
Therefore interest earned =380× 0.13×1
=$49.4
Answer:
D = $8637.45
Step-by-step explanation:
Rate = 3.65% = 0.0365
Principal = 5000
Time (t) = 15 years
N = 12 (since its compounded monthly)
Compound interest (A) = P(1 + r/n)^nt
A = 5000(1 + 0.0365 / 12)^15*12
A = 5000(1 + 0.00304)¹⁸⁰
A = 5000(1.00304)¹⁸⁰
A = 5000 * 1.7269
A = 8634.86
The investment would worth $8634.86

When x=1 and -2 so it is C
Answer:
y=-2x-13
Step-by-step explanation:
y-y1=m(x-x1)
y-(-13)=-2(x-0)
y+13=-2x
y=-2x-13
