Answer:

The cost per pound for turkey is 0.87.

A 12-pound turkey would cost $10.44.

The turkey weighed 22 pounds.

Step-by-step explanation:

You know that the cost of a turkey, c, that is w pounds is represented by the equation c=0.87*w

<em>What is the cost per pound for the turkey?</em>

The direct proportionality function is called any function in which the dependent variable (y) is obtained by multiplying the independent (x) by a constant value. This type of function is called a linear function and has an expression of the form:

y=m*x

where m is the constant of proportionality.

Comparing both expressions, it is observed that the constant of proportionality for this case has a value of 0.87, and indicates the cost per pound for the turkey. That is, the cost per pound for turkey is 0.87.

<em>How much would a 12 pound turkey cost? </em>

Being c=0.87*w, then you know that the value of w is 12 pounds. Replacing:

c= 0.87*12

you get:

c=10.44

A 12-pound turkey would cost $10.44.

<em>Karen spent $19.14 on a turkey. How many pounds did it weigh?</em>

Being c=0.87*w, then you know that the value of the cost c is $19.14. Replacing:

19.14= 0.87*w

and solving you get:

w=19.14 ÷0.87

w= 22

The turkey weighed 22 pounds.

A. the series is absolutely convergent.
Dovator [93]
\displaystyle\sum_{n=1}^\infty\left(1+\frac5n\right)^n

Notice that

\displaystyle\lim_{n\to\infty}\left(1+\frac5n\right)^n=e^5\neq0

which means the series is divergent. So if this is one of those "select all that apply" questions, then both (c) and (j) are the only choices that do.
