Temka [501]
Hello!

This makes a triangle

The cat is 20 ft high

The triangle is 20 feet high

The is 6 ft between the ladder and the tree

The base is 6 ft long

You use the Pythagorean theorem to solve this

a^{2} + b^{2} =c^{2}

a and b are the base and height

put in the values you know

6^{2} + 20^{2} = c^{2}

square the numbers

36 + 400 = c^{2}

Add

436 = c^{2}

Take the square root of 436

20.9 = c

Since this is lower than the length of the ladder the ladder is long enough

The answer is yes

Hope this helps!

Which expression is equivalent to the following complex fraction?
True [87]

Answer:

<h2>A. -2y+5x/3x-2y</h2>

Step-by-step explanation:

Given the complex fraction;

-\frac{2}{x} +\frac{5}{y} / \frac{3}{y} - \frac{2}{x} \\

First we will find the LCM of the numerator and the denominator as shown below;

\frac{-2y+5x}{xy} /\frac{3x-2y}{xy}

Then we divide both equation by multiplying the numerator by the reciprocal of the denominator as shown;

= \frac{-2y+5x}{xy} * \frac{xy}{3x-2y}  \\= \frac{-2y+5x}{3x-2y} \\

This gives the required answer

Given matrices S and T below, which statement is true?
harina [27]
The matrices are
S =(4 11                           T= ( -8 11
      -3  -8)                                 3  4 )
Inverse of a matrix is a matrix derived from another matrix such that if you pre- multiply it with the original matrix you get a unit matrix.
if we multiply S and T
 ST will be 
        ( 4 11    ×      (-8 11   = ( 1 0
          -3 -8)           -3 -4)         0 1)
and also TS
          ( -8 11      ×     (4 11  = ( 1 0
             -3 -4)            -3 -8)       0 1)
therefore, matrices S and T are inverses of each other because ST = TS= I
