Your answer is the first option, -10

Laws of Indices states that a^b x a^c = a^(b + c), therefore 9^-8 x 9^-2 = 9^(-8 - 2) = 9^-10

Answer:

-10

Step-by-step explanation:

9^-8 x 9^-2 = a^b

We know that x^y * x^z = x^(y+z)

9^-8 x 9^-2 = 9^(-8+-2) = 9^(-10)

a= 9  

b = -10

Can some one please help me

Given:

A figure of a right triangle with perpendicular 500 m  and hypotenuse x.

To find:

The value of x.

Solution:

If a transversal line intersect two parallel lines, then alternate interior angles are congruent.

Using the above definition the measure of angle opposite to the perpendicular is 40 degrees.

In a right angle triangle,

\sin \theta =\dfrac{Perpendicular}{Hypotenuse}

In the given triangle,

\sin 40^\circ =\dfrac{500}{x}

x=\dfrac{500}{\sin 40^\circ }

x=\dfrac{500}{0.6427876}

x=777.8619

Round the value to the nearest tenth.

x\approx 777.9

Therefore, the value of x is 777.9 m.
