The correct question is
What is the value of x in the following equation (1/5)^x=5^8 

Applying logarithms both members
log(1/5)^x=log(5^8) 
x*log(1/5)=8*log(5)
x=8*log(5)/log(1/5)

we know that
log (1/5)----> log (1)-log (5)----> 0-log (5)-----> -log (5)
so
x=8*log(5)/-log (5)------> x=-8

the answer is
-8

Step-by-step explanation:

As per the problem, the given triangle is a right triangle. This is signified by the box around one of its angles, this box states that the angle it is surrounding is a right angle.

Since it is a right triangle, one can use the Pythagorean theorem to solve this problem. The Pythagorean theorem states that; (a^2 + b^2 = c^2), where (a) and (b) are the legs of the right triangle, or the sides adjacent to the right angle. (c) is the hypotenuse or the side opposite the right angle.

Substitute in the given values and solve, note that (a) represents the unknown leg (side).

a^2 + b^2 = c^2\\\\a^2 + (\sqrt{19})^2 = (100)^2\\\\a^2 + 19 = 100

Inverse operations,

a^2 + 19 = 100\\-19\\\\a^2 = 81\\\\a = \sqrt{81}\\\\a = 9

Find the surface area of the cylinder to the nearest tenth of a square unit. use 3.14 for pi
Alborosie

Given:

  • Height of cylinder is 18.2 cm
  • Radius of cylinder is 3 cm

~

To Find?

  • Surface area

~

Solution:

Using formula:

  • Surface area of cylinder = 2πr (h + r)

~

Substituting values in the formula:

\longrightarrow \sf 2 × 3.14 × 3 (18.2 + 3)

\longrightarrow \sf 6.28 × 3 (21.2)

\longrightarrow \sf 18.84 × 21.2

\longrightarrow \sf 399.4 cm²

~

  • Hence, (B) 399.4 cm² is right answer.
