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}

a + 2b =11---------(2)

on mutlplying by7 in eq 2

= 7a+14b=77-------(3)

from eq(1) and (3) (on substracting)

7a+14b=77

7a-3b=26

________

=-17b=51

b=51/17

b=3

on putting value of b in eq 1

7a-3b = 26

=7a-9=26

7a=35

a=5

Novay_Z [31]

Answer:

Interest rate is about 12.246%

The initial deposit doesn't matter because when you divide both sides by the initial deposit you're always left with (1+i)ⁿ=2

Step-by-step explanation:

4000(1+i)^6=8000\\(1+i)^6=2\\1+i=\sqrt[6]{2} \\1+i=1.122462048\\i=.12246

<span>15l - 27c = 18 </span>
<span>62c = 31 </span>

<span>c = 1/2 pint </span>
<span>l = 2.1 pint </span>
