SUPER EASY MATH! WILL MARK BRAINLIEST!Given the vectors in component form: r = ⟨8, 4⟩

s = ⟨–3, –4⟩

t = ⟨–5, 1⟩

Perform the operations.

5r – 3s + 8t

What is the magnitude and direction angle of the resultant vector?

A. 10.8, θ = 56.3°
B. 18.4, θ = 119.4°
C. 41.0, θ = 77.3°
D. 97.6, θ = 24.2°

9514 1404 393

  C.  41.0, θ = 77.3°

Step-by-step explanation:

The sum is ...

  5(8, 4) -3(-3, -4) +8(-5, 1) = (5·8-3(-3)+8(-5), 5·4-3(-4)+8·1)

  = (40+9-40, 20+12+8) = (9, 40)

The magnitude is ...

  √(9² +40²) = √1681 = 41

The angle is ...

  arctan(40/9) ≈ 77.3°

The resultant magnitude and direction is 41∠77.3°.

answer: 26

step-by-step explanation:

well, michelle wanted to measure the height of her school's flagpole she placed a mirror on the ground 48 feet from the flagpole then walk backwards until she was able to see the top of the pole in the mirror her eyes were 5 feet above the ground and she was 12 ft from the mirror using similar triangles find the height of the flagpole to the nearest tenth of a foot find the geometric mean of them pair of numbers. its easy math

439400

step-by-step explanation:

130^2 = 16900

16900*26 = 439400
