Answer:

A -60i - 14j

Step-by-step explanation:

u = -9i + 8j

v = 7i + 5j

2u = 2(-9i + 8j) = -18i + 16j

6v = 6(7i + 5j) = 42i + 30j

2u - 6v

(-18i + 16j) - (42i + 30j)

(-18i - 42i) + (16j-30j)

-60i - 14j

Mama L [17]

Answer:

Option B.

Step-by-step explanation:

Eric states the applied interest is simple interest. We need to check whether the this statement is true or false.

In simple interest, the amount of deposit increased at a constant rate. It means the difference between future values of any two consecutive years will same.

Difference between future values of first two years.

d_1=210.13-205.00=5.13

Difference between future values of 2nd and 3rd year is

d_2=215.38-210.13=5.25

Since d₁≠d₂, therefore, the given statement is false.

Thus, the correct option is B.
