Let u = < -9, 4> , v = < 8, -5> . find u - v.

<8, -5>

Step-by-step explanation:

We know that the formula for the substraction of two vectors is:

(a, b) - (c, d) = (a-c, b - d), it means you need to subtract

If u = (-9, 4) and v= (8, -5), then the result is:

(-9, 4) - (8, -5) = (-9 -8, 4- (-5)) = (-17, 9)

i think the answer is b.

step-by-step explanation:

not 100% sure though.

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

hope this ! ~
