16m because if you use the pythagorean therum the rest of the pole is 10m long, which you add to the base of the pole.

Answer:

4.5

Step-by-step explanation:

First we need to turn the ratio of 1 : 3 into a fraction

1:3 = 1/3

Next we need to square that fraction

1 x 1 = 1

3 x 3 = 9

Then we turn those numbers into a fraction

1/9

We turn the .5 into a fraction

.5/x

And cross multiply both fraction by each other

1/9 x .5/x

1 x X = X

9 x .5 = 4.5

So

4.5 = X

Answer:

B) 0.85

Step-by-step explanation:

By definition, complementary angles add to 90 degrees.

The given angle 58 degrees is complementary to 90-58 = 32 degrees. The two angles 58 and 32 add to 90.

Therefore, cos(32) = 0.848 = 0.85

Answer:

A. $(x^{2/7})(y^{-3/5})$

Step-by-step explanation:

<u>The numerator is:</u>

$\sqrt[7]{x^2} = (x^2)^{1/7} = x^{2/7}\\$

<u>The denominator is:</u>

$\sqrt[5]{y^3} = (y^3)^{1/5} = y^{3/5}$

<u>The fraction is equivalent to:</u>

$\frac{x^{2/7}}{y^{3/5}} =$
$(x^{2/7})(y^{-3/5})$

Correct choice is A
