Mathematics
1 answer:
ANEK [815]3 years ago

Multiplying a vector by a scalar means to multiply each coordinate of the vector by said scalar.

So, we must multiply both entries by 7:

u=(-8, -9)\implies 7u=(-8\cdot 7, -9\cdot 7) = (-56, -63)

Jamie deposits $1,600 into two different savings accounts. Account I is compounded annually at an interest rate of 2.75%. Accoun
GrogVix [38]

Answer:

Step-by-step explanation:

Considering account I, we would apply the formula for determining compound interest which is expressed as

A = P(1 + r/n)^nt

Where

A = total amount in the account at the end of t years

r represents the interest rate.

n represents the periodic interval at which it was compounded.

P represents the principal or initial amount deposited

From the information given,

P = $1600

r = 2.75% = 2.75/100 = 0.0275

n = 1 because it was compounded once in a year.

t = 2 years

Therefore,

A = 1600(1 + 0.0275/12)^1 × 2

A = 1600(1.0275)^2

A = $1689.21

Considering account II, we would apply the formula for determining simple interest which is expressed as

I = PRT/100

Where

I represents interest paid on the investment.

P represents the principal or amount invested

R represents interest rate

T represents the duration of the investment in years.

From the information given,

P = 1600

R = 3.5

T = 2 years

I = (1600 × 3.5 × 2)/100 = $112

Total balance after 2 years is

112 + 1600 = $1712

the difference between the two accounts after 2 years is

1712 - 1689.21 = $22.79

A rectangle has a length of 42 inches and a width of 14 inches. Which of the following is not equal to the ratio of the rectangl
Temka [501]
The ratio of the rectangle's length to its width is 42/14 which simplifies to 3/1 by factoring out 14 out of the numerator and denominator.
Any ratio that is not 3:1, or a multiple of 3:1, is not equal.

List of Equal Ratios: 6:2, 9:3, 12:4, etc.
