What are the coordinates of the point (-9,10) after being reflected across the x-axis on a coordinate plane?

Answers

Answer:

-9,-10

Step-by-step explanation:

The X is on the axis and nothing will change, and the Y will flip sides.

The coordinates of the point after being reflected across the x-axis are (-9, -10).

When a point is reflected across the x-axis on a coordinate plane, its y-coordinate changes sign while its x-coordinate remains the same.

The original point is (-9, 10).

After reflecting across the x-axis, the y-coordinate changes sign, so the new point becomes:

(-9, -10).

So, the coordinates of the point after being reflected across the x-axis are (-9, -10).

evaluate the following expression log^6 8. round your answer to two decimal places
A.0.90
B.1.16
C.2.08
D.0.86

Answers

Answer:

B. 1.16

Step-by-step explanation:

Correct!

The following expression [tex]log^6 8[/tex] evaluates to 0.86. So, The correct  answer is 0.86.

We can evaluate the expression log^6 8 as follows:

[tex]log^6 8 = log 8 / log 6 = 0.90309...[/tex] which rounds to 0.86 to two decimal places.

Therefore, the correct answer is D.

Logs:

The exponential function's inverse is known as the logarithm, or log. In other terms, a number's logarithm is the power that a different number, b, must be raised to in order to equal that number.

The expression log x = b represents a logarithm and is symbolized by the symbol "log". This implies that b is equivalent to x when raised to the power of log b.

For instance, since 2 raised to the power of 3 is 8, the logarithm of 8 to the base 2 is 3.

Calculus, statistics, computer science, and other branches of mathematics all make use of logarithms. Numerous more practical uses include determining pH levels and decibel levels.
