Answer:

174879 units

Step-by-step explanation:

Given that The Elmina Wilson Company produces spaghetti sauce.

Fixed costs =1,329,050 $

Selling price per 64 oz= $12.40$

Variable cost per can = $4.80$

Contribution = S-V=Selling price - var cost = 7.60 $

Break even poin in no of units = Fixed cost/Contribution per unit

= $\frac{1,39,050}{7.60} \\=174878.94\\=174879$

I really really really need help!!!!

For $f$ to be continuous at $x=1$ , you need to have the limit from either side as $x\to1$ to be the same.

$\displaystyle\lim_{x\to1^-}f(x)=\lim_{x\to1^-}(|x-1|+2)=2$
$\displaystyle\lim_{x\to1^+}f(x)=\lim_{x\to1^+}(ax^2+bx)=a+b$

If $a=2$ and $b=3$ , then the limit from the right would be $2+3=5\neq2$ , so the answer to part (1) is no, the function would not be continuous under those conditions.

This basically answers part (2). For the function to be continuous, you need to satisfy the relation $a+b=2$ .

Part (c) is done similarly to part (1). This time, you need to limits from either side as $x\to2$ to match. You have

$\displaystyle\lim_{x\to2^-}f(x)=\lim_{x\to2^-}(ax^2+bx)=4a+2b$
$\displaystyle\lim_{x\to2^+}f(x)=\lim_{x\to2^+}(5x-10)=0$

So, $a$ and $b$ have to satisfy the relation $4a+2b=0$ , or $2a+b=0$ .

Part (4) is done by solving the system of equations above for $a$ and $b$ . I'll leave that to you, as well as part (5) since that's just drawing your findings.

Answer:

55 ft... The ladder must extend 55ft

Step-by-step explanation:

$c = \sqrt{a ^{2} + b ^{2} } \\ = \sqrt{33 ^{2} + 44 ^{2} } \\ = \sqrt{1089 + 1936 } \\ = \sqrt{3025} \\ c = 55$

Analyze the zeros of f(x)=x^4-3x^3-2x^2+3x-5

ikadub [295]

Answer:

a. 2

Step-by-step explanation:

The given function is

$f(x)=x^4-3x^3-2x^2+3x-5$ .

We can see from the graph that the graph has two x-intercepts.

This means that the function has two real zeros.

By the fundamental theorem of Algebra, the function is supposed have four roots since it is a polynomial of degree 4.

Therefore, the other two zeros are complex.
