Vector combinations linear combination a linear combination of the vectors is a vector w-a, +az7++a, definition the scalars , are called the coefficients of the linear combination. let 3 = []). 1: =(-1), and w = 23, + 3 write w as a column vector. when is written as a linear combination of , and 1, what are the coefficients of y, and ,? 7.2 is a linear combination of v, and 0? a linear combination of, and 7,? 74 is a linear combination of , and v? 7.5 can you find a vector in r2 that isn't a linear combination of y, and v? 7.6 can you find a vector in r that isn't a linear combination of

f(x) = y

f(-3) = -5

step-by-step explanation:

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.

7.9m and 4.3°

step-by-step explanation:

let east be +x and north be +y, x = distance * cos θ, y = distance * sin θ  

for 3.5 south, y = -3.5  

for 8.2, x = 8.2 * cos 30 and y = 8.2 * sin 30  

for 15 west, x = -15  

total x = 8.2 * cos 30 – 15 ≈ -7.9  

total y = -3.5 + 8.2 * sin 30 = 0.6  

magnitude = [(8.2 * cos 30 – 15)^2 + 0.6^2)]^0.5  

the magnitude is approximately 7.9 m  

tan θ = y/x = 0.6/-7.9  

the angle is approximately 4.3˚ north of west
