Answer:
Number one is 4p+8-9. 8-9= -1 So, 4p-1. Divide both by 4. p=.25
I'm assuming that the matrix is a 2 x 2 matrix.
| -2 5 |
| 4 3 |
To determine the determinant of the matrix, we simply find the difference of the product of its diagonals.
| a b |
| c d | → ad - bc = determinant
| -2 5 |
| <span>4 3 | </span>→ [(-2) * 3] - (5*4) = -6 - 20 = -26
Even though the determinants are place in an absolute-value bars, they can still be negative form.
The determinant in the above matrix is -26.
Answer:
The answer matches with option A.
Step-by-step explanation:
We have to find the product of 100,000 and 1,000,000 using scientific notations.
Now, 100,000 can be written as and
1,000,000 can also be written as .
So, the product will give
100,000 × 1,000,000
=
=
=
So, the answer matches with option A. (Answer)

Answer:
sin(2*36.86989765) and get .96 or 24/25
7/25
Step-by-step explanation:
Start by solving for P
sinP=3/5
take the arcsin or sin^-1 and get
p=36.86989765
Then multiply by 2 and take the sin and get
sin(2*36.86989765) and get .96 or 24/25
Then take cos(2*36.86989765)=.28 or 7/25
