A food packet is dropped from a helicopter and is modeled by the function f(x) = −15x2 + 6000. The graph below shows the height

Dafna1 [17]

The given function f(x)=-15x²+6000 represent a parabola or a quadratic equation.

Where x= time (in seconds) and f(x)= height (in feet).

Domain is the set of values of x at which the function must be defined. But there is no restriction for a quadratic function because it can take any value of x. Hence, domain of all quadratic functions or parabola are always

-∞≤x≤∞ or all real numbers.

So, domain of given function is " all real values of x".

If you know that log5 (2) - log5 (12) = 0, which of the following is false?

garri49 [273]

Answer:

B

Step-by-step explanation:

A is correct because $log_5(12)$ was added on both sides, which is supported by the Additive Property of Equality

C is correct because the Quotient Property of Logarithms states that $log_bM-log_bN=log_b(\frac{M}{N} )$

so $log_5(x)-log_5(12)=log_5(\frac{x}{12} )$ is correct

D is correct because using the fact that $log_5x=log_512$ it is easy to figure out that x=12

For B, there is no property supporting that statement.

Samantha works at an animal shelter. She decides to track the total number of kittens that are brought in. The equation k=4w+3 r

mel-nik [20]

Answer:

B

Step-by-step explanation:

The equation $k=4w+3$ represents the total number of kittens, where $w$ represents <u>the number of weeks that have passed since Samantha started counting.</u>

This means options C and D are false, because they say <u>the total number of kittens that have come into the shelter</u>.

$w$ represents the number of weeks, weeks can be counted 0 weeks, first week, second week and so on, so option B is true (the domain is all whole numbers) because 0, 1, 2, 3, ... are whole numbers.

Number of weeks can't be a negative number. Since "real numbers" include negatives, therefore, we exclude option A.
