Find the product .-2 [7 -4 0]

Mathematics
1 answer:
Makovka662 [10]3 years ago
4 0
It says find the product, so that means multiplication
-2[7 -4 0] = [-14 8 0]                                           solving: [-14 8 0] [-3 0 5]
                                                                           [42+0+70     -24+0+40   0+0+0]  
  [-14 8 0] * [-3 0 5] = [112 0 -30]                           = [112  16  0]
                                                                          [112  16  0]*[6  2  1]
[112 0 -30]* [6 2 1] = [1008 114 0]                  [672+224+112    96+32+16   +0]
                                                                          =[1008  114  0].

5x + 3y = -2
tamaranim1 [39]

Answer:

x = -1 , y = 1

Step-by-step explanation:

Solve the following system:

{5 x + 3 y = -2 | (equation 1)

3 x + 2 y = -1 | (equation 2)

Subtract 3/5 × (equation 1) from equation 2:

{5 x + 3 y = -2 | (equation 1)

0 x+y/5 = 1/5 | (equation 2)

Multiply equation 2 by 5:

{5 x + 3 y = -2 | (equation 1)

0 x+y = 1 | (equation 2)

Subtract 3 × (equation 2) from equation 1:

{5 x+0 y = -5 | (equation 1)

0 x+y = 1 | (equation 2)

Divide equation 1 by 5:

{x+0 y = -1 | (equation 1)

0 x+y = 1 | (equation 2)

Collect results:

Answer: {x = -1 , y = 1

What is the length of s?​
Serggg [28]

Answer:

10

Step-by-step explanation:

We will use trigonometry to solve this problem.

We see that the side provided is the hypotenuse and the side we are looking for is opposite to the angle provided. Thus, we will use sin since sin uses opposite/hypotenuse.

Now we solve.

sin45 = x/14

sin45 * 14 = x

x = 9.899494936611665
