This is due in an hour! will give brainliest for correct answer!

For this, all you need to do is plug in the x and y values.

When adding, add the two x values together to get your final x value, and add your y values to get your final y value.

a + b = (3 + (-2), 2 + (-1))

a + b = (1, 1)

When subtracting, subtract the two x values from each other to get your final x value, and subtract your y values to get your final y value.

a - b = (3 - (-2), 2 - (-1))

a - b = (5, 3)

When multiplying set a by 2, all you need to do is distribute.

2a = (3x2, 2x2)

2a = (6, 4)

For this, all you need to do is multiply the x and y values in set a by 2, and multiply the x and y values in set b by 4. Then add the product of the x value in set a to the product of the x value in set b.

2a + 4b = (2(3) + 4(-2), 2(2)+ 4(-1))

2a + 4b = (6 + (-8), 4 + (-4))

2a + 4b = (-2, 0)

For the last one you just need to find the absolute value.

|a| = (3, 2)

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .

step-by-step explanation:

this is the formula: v = the value of investment at the end of the time period

p = the principal amount (the initial amount invested)

r = the annual interest rate

n = the annual frequency of compounding (how many times a year interest is added)

t = the number of years the money is invested

^ means raise to the power of
