For a 2x2 matrix, the determinant is the absolute value of ad-bc
in this case, a=4, b=-7, c=3, d=-2
4*(-2)=-8
-7*3=-21
-8-(-21)=13
so the answer is D

Is 0.2487 a interger
BabaBlast [244]

No.  0.2487 is not an interger.

There are two big reasons for this:

1).  There is no such thing as an ' interger ',
       so no number could be one.
       You probably mean ' integer '.

2).  An integer is a whole number ... a number
      with no fraction part and no decimal part.
      0.2847  is all decimal, and not even big enough
      to make the smallest whole number.  (That's ' 1 '.)

A kite is flying above the ground
andriy [413]

The height of the kite above the ground is 90.63 feet.

<u>Step-by-step explanation:</u>

The angle of elevation of the kite is (θ) 65°.

The distance between the kite and its end is (hypotenuse)100 feet.

To find the height (x) of the kite flying above the ground.

we know that sin(θ) =\frac{height}{hypotenuse}.

sin 65°=\frac{x}{100} .

sin 65° =  0.90631.

0.90631 ×100=x.

90.63=x.

∴The height of the kite above the ground is 90.63 feet.
