Anastaziya [24]

Answer:

$C = 1000S + 500B$

Step-by-step explanation:

Given

$S = Banana\ Splits$

$B=Bacon\ Rolls$

Reading through the question, we have:

Number of calories per serving:

$S \to 1000$

$B \to 500$

Let

$x = Cholesterol$

$y =Sugar$

So, we have:

Each serving of S

$x \to 1S$

$y \to 3S$

Each serving of B

$x \to 4B$

$y \to 1B$

Recommendation

$x \to \le 10$ - i.e. not more than 10 units of cholesterol

$y \to \ge 2 \& \le 9$ i.e. At least 2units but not more than 9 units of sugar

So, the constraints are:

$S + 4B \le 10$

$3S + B \ge 2$

$3S + B \le 9$

Recall that the calories per serving is:

$S \to 1000$

$B \to 500$

Hence, the objective function is:

$C = 1000S + 500B$

Evaluate each expression. Determine if the final simplified form of the expression is positive or negative -42 (-4)2 42

Sati [7]

Answer:

Given the expression:

$-4^2$

we know:

$4^2 = 4 \times 4 = 16$

then;

$-4^2 = -16$

Therefore, the value of expression $-4^2$ is -16 i.e negative.

$(-4)^2$

we know:

$4^2 = 4 \times 4 = 16$

$(-1)^2 = 1$

then;

$(-4)^2 = (-1)^2 \cdot (4)^2= 16$

Therefore, the expression $(-4)^2$ is 16 i.e Positive.

$4^2$

we know:

$4^2 = 4 \times 4 = 16$

then;

$4^2 = 16$

Therefore, the expression $4^2$ is 16 i.e Positive.

Suppose a principal amount of $2079 were invested into a simple interest account that pays an annual rate of 2.31% then the amou

Anna35 [415]

Answer:

The amount of interest earned at the end of 14 years would be $672.3486

Step-by-step explanation:

This is a simple interest problem.

The simple interest formula is given by:

$E = P*I*t$

In which E are the earnings, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.

In this problem, we have that:

$P = 2079, I = 0.0231, t = 14$

$E = 2079*0.0231*14 = 672.3486$

The amount of interest earned at the end of 14 years would be $672.3486
