Need help with exponential functions quick <br> 30 points
lisov135 [29]

Answer:

Since the independent variable x is not the exponent, y = - 7 x^{8} does not represent an exponential function.

Step-by-step explanation:

The general expression of an exponential function is f(x) = a^{x}, where a > 0 and a ≠ 1

Now the given function is y = - 7 x^{8} ..... (1)

So, we can say that the function f(x) = y is not an exponential function as x is not in power of any constant.

Therefore, since the independent variable x is not the exponent, y = - 7 x^{8} does not represent an exponential function. (Answer)

What is the height, x, of the equilateral triangle?
e-lub [12.9K]

Using the Pythagorean Theorem, the height of the equilateral triangle is given by:

A. h = 7\sqrt{3} inches.

<h3>What is the Pythagorean Theorem?</h3>

The Pythagorean Theorem relates the length of the legs l_1 and l_2 of a right triangle with the length of the hypotenuse h, according to the following equation:

h^2 = l_1^2 + l_2^2

For this problem, we have that:

  • The height is one side of the triangle.
  • The other side is half the length, of 7 in.
  • The hypotenuse is the length, of 14 in.

Hence the height is found as follows:

h^2 + 7^2 = 14^2

h = \sqrt{147}

h = \sqrt{49 \times 3}

h = 7\sqrt{3} inches.
