Answer:

3 33/56

Step-by-step explanation:

16 3/4 convert to fraction: 67/4

4 2/3 convert to fraction: 14/3

67/4 divided by 14/3 = 67(3) / 4(14)

201/56

simplify

Answer:

Step-by-step explanation:

First turn them into improper fractions.

16 3/4 ----> 67/4

4 2/3 -----> 14/3

67/4÷14/3= ?

Now use keep, change, flip strategy

67/4×3/14= 201/56

Now simplify 3 33/56

Answer Step-by-step explanation:

$\huge\boxed{A)-1}$

$The~average~rate~of~change~of~the~given~quadratic~function~on~the$ $interval~0$ ≤ x ≤ $4$ $is~the~slope~of~the~secant~line~connecting~the~points~(0,f(0))~and~(4,f(4)).$

$The~average~rate~of~change~is:$

$=\frac{f(4)-f(0)}{4-0}$

$Now,from~the~graph,f(0)~is~0~and~f(4)~is~-4.$

$We~plug~in~these~values~to~obtain;$

$=\frac{-4-0}{4-0}$

$And~then,this~simplifies~to:$

$=\frac{-4}{4}$

$which~is~obviously:$

$=-1$

$Thus,~the~average~rate~of~change~for~the~given~quadratic~function$ $whose~graph~is~shown~on~0$ ≤ x ≤ $4~is~=-1.$

is the following statement sometimes,always or never true?negative - positive =negative defend your answer

Elanso [62]

It is always negative, because it keeps going down on the number line. Say it is negative 8 minus 5, it would be negative 13, because it adds to the negatives, so it would go deeper into the negatives.

At the beginning of an environmental study, a forest covered an area of 1500km^2. Since then, the area has decreased by 6.3% eac

geniusboy [140]

The <em><u>correct answer</u></em> is:

$y=1500(0.937)^t$

Explanation:

An exponential function is of the form

$y=a\times b^x$ , where a is the initial population, b is 1 plus the amount of yearly change, and x is the number of years.

For our problem, a, the initial population, is 1500.

The yearly change is 6.3%; 6.3% = 6.3/100 = 0.063. Since it is decreasing, this is negative; 1+(-0.063) = 0.937.

We use t as the number of years.

This gives us

$y=1500(0.937)^t$
