Answer:

The address of the element 14 in matrix D is d23 (First option)

Step-by-step explanation:

The address of an element of Matrix D is written as dfc, where "f" is the number of the row the element belongs and "c" is the number of the column the element belong.

In this case the element 14 is in the second row, then f=2

and it is in the third column, then c=3

Then, the address of the element 14 is dfc=d23

for this problem you just multiply the 20 by 2=40
and then you add 40+3=43
which will equal
$\frac{43}{20}$

35.G
if you divide
$58 \div 25 = 2.32$
so G
$\frac{58}{25}$

36. C
$\frac{5}{5} = 1$
so if you subtract
$\frac{6}{5} - \frac{5}{5}$
will equal

$\frac{1}{5}$
$1 \frac{1}{5}$

A telephone pole has a wire to its top that is anchored to the ground. The distance from the bottom of the pole to the anchor po

Bumek [7]

Answer:

The height of the pole is 105ft,

Step-by-step explanation:

Let us call $h$ the height of the pole, then we know that the distance from the bottom of the pole to the anchor point is 49, or it is $h - 49$ .

The wire length $d$ is 14 ft longer than height $h$ , hence

$d= h+14$ .

Thus we get a right triangle with hypotenuse $d= y+14$ , perpendicular $h$ , and base $h-49$ ; therefore, the Pythagorean theorem gives

$(h-49)^2+h^2 = (h+14)^2$

which upon expanding we get:

$h^2-98h+2401 = h^2+28h+196$

further simplification gives

$h^2-126h+2205=0$ ,

which is a quadratic equation with solutions

$h =21ft\\h = 105ft.$

Since the first solution $h =21ft$ will give the triangle base length of $21ft-49ft = -28ft$ which is negative; therefore, we disregard it and pick the solution $h = 105ft$ .
