Answer:

The correct option is C.

Step-by-step explanation:

The given expression is

0.8^{x-3}

According to the property of exponent.

x^{a-b}=\frac{x^a}{x^b}

Using this property we get,

0.8^{x-3}=\frac{0.8^x}{0.8^3}

Therefore the correct option is C.

What are the coordinates of the terminal point for 0=330
Ira Lisetskai [31]

Answer: Option C.

Step-by-step explanation:

The coordinates (x,y) of a terminal point for an angle θ are:

x = cos(θ) and y = sin(θ).

In this case, we have θ = 330°.

Then we have:

x = cos(330°) = 0.866 = (√3)/2

y = sin(330°) = -0.5 = -1/2

then the coordinates of the terminal point are ((√3)/2, -1/2)

Then the correct option is c.

The cost for each car entering President George Bush Turnpike at Beltline road is $0.75. The equation that represents this relat
vesna_86 [32]

From the definition of a function, a function associates every element of the domain to a unique element in the codomain.

In other words, if two elements are equal in the domain, then their images should also be equal.

Since, x represents the number of cars, we consider the universal set as N, the set of all natural numbers.

Let x, y ∈ N and x = y

Then, 0.75x = 0.75y

⇒ f(x) = f(y)

Therefore, images are equal, whenever elements are equal.

Hence, the function f(x) = 0.75x is a function. Also, note that the domain of the function is the set of all natural numbers and the range is the set of real numbers.
