Answer:

  -864

Step-by-step explanation:

The determinant of a matrix product is the product of the determinants. The determinant of a transpose is the same as the determinant of the original. Hence ...

  |AB^5C^T|=(4)(-2)^5(\frac{1}{4})=-32

The multiplication of an n×n matrix by a scalar 'a' multiplies its determinant by a^n, so the desired determinant is ...

  |3AB^5C^T|=3^3(-32) = \boxed{-864}

I need help ASAP pleaseee helppp I’ll maker brainliest:((<br> It’s number 2
siniylev [52]

Answer:

J

Step-by-step explanation:

When finding the distance between the two points you use the formula

d(distance)= square root of ( x2-x1)^2+(y2-y1)^2. So since you have the two points you just plug them into the formula to get

square root of (5-(-3))^2+(2-(-5))^2 and if you put that in a calculator you get 10.63014581. Then you just round to the nearest tenth and get the final answer of 10.6 (J)
