Question

(-9,3-1,7)•(2,6+(-5,9)-4/5-4/7):(5 7/3 -7 11/12)​

Answer 1

Ответ:

(-9.3 - 1.7) * (2.6 + (-5.9)) = -136.62

(-4/5 - 4/7) / (5 7/3 - 7 11/12) = -0.007918

Answer 2

To calculate the given expression, you need to perform the vector dot product and scalar division. Let's break it down step by step:

1. Dot Product: (-9, 3-1,7) • (2, 6+(-5,9)-4/5-4/7)

   First, we simplify the vectors: Vector 1: (-9, 1.3) Vector 2: (2, 6 - 5.9 - 4/5 - 4/7)

   Vector 2 simplifies to: (2, 0.1 - 5.9 - 0.8 - 0.5714)

   Now, let's calculate the dot product: Dot Product = (-9 * 2) + (1.3 * (0.1 - 5.9 - 0.8 - 0.5714))

   Dot Product = -18 + (1.3 * (-6.2714))

   Dot Product ≈ -18 - 8.16482

2. Scalar Division: (5 7/3 - 7 11/12)

   To divide by a scalar, you simply divide each component by that scalar. Scalar Division = (5 7/3 - 7 11/12) ÷ 8.16482

   For each component, divide by 8.16482: (5 7/3) ÷ 8.16482 = (5 7/3) / 8.16482 (7 11/12) ÷ 8.16482 = (7 11/12) / 8.16482

   Calculate each component individually: (5 7/3) / 8.16482 ≈ 0.6614 (7 11/12) / 8.16482 ≈ 0.9096

Now, you have the result of the dot product and the scalar division:

Dot Product ≈ -26.16482 Scalar Division ≈ (0.6614, 0.9096)

So, the final result of the expression is approximately -26.16482 divided by the vector (0.6614, 0.9096):

Result ≈ (-26.16482 / 0.6614, -26.16482 / 0.9096) Result ≈ (-39.5533, -28.761)

The final result is approximately (-39.5533, -28.761).
