Let the leading term of the polynomial, f(x), be axⁿ.

Examine the possibilities.
n a x -> - ∞ x -> +∞
------- ---- ----------- ------------
even a>0 f -> +∞ f -> +∞ Not true
even a<0 f-> - ∞ f-> -∞ True
odd a>0 f-> -∞ f-> +∞ Not true
odd a<0 f-> +∞ f-> -∞ Not true

Answer:
(a) the degree of the polynomial is even, and
(b) the coefficient of the leading term is negative.

50 POINTS!!!!! HELP Soybean meal is 16% protein; cornmeal is 8% protein.How many pounds of each should be mixed together in orde

tia_tia [17]

The first thing we are going to do for this case is define variables.
We have then:
x: Amount of soybean meal
320 - x: quantity of cornmeal
We now write the equation that models the problem:
$0.16x + 0.08 (320-x) = 0.09 (320)
$
Rewriting we have:
$0.16x + 25.6 - 0.08x = 28.8
$
From here, we clear x:
$0.16x - 0.08x = 28.8 - 25.6

0.08x = 3.2

x = 3.2 / 0.08

x = 40$
Then, the amount of Soybean meal is:
$x = 40 lb
$
The amount of cornmeal is:
$320 - x = 320 - 40 = 280 lb
$
Answer:
cornmeal: 280 lb
Soybean: 40 lb.

What is (7x-2y)(3x+5y)

Ymorist [56]

(7x - 2y) (3x +5y) ( First open brackets)

= 21x² + 35xy - 6xy - 10y² ( solve like terms)

= 21 x² - 10y² + 29xy.

Biologists have noticed that the chirping rate of crickets of a certain species is related to temperature, and the relationship

Step2247 [10]

Answer:

$y=\frac{1}{6}x+\frac{307}{6}$

Step-by-step explanation:

Basically the word problem here is trying to get us to find the line using the two points (113,70) and (173,80).

It also tells us by saying that we're modeling the temperature that we're going to be using the y = mx + b formula. m and b are what we'll mainly be looking for.

Let's start by finding m, the slope. We'll be using the point slope formula:

$\frac{y_2-y_1}{x_2-x_1} \\\frac{70-80}{113-173}\\\frac{10}{60}\\ \frac{1}{6}$

So m = 1/6.

Now let's use that m and choose one of the points (I chose (113,70) ) to plug in everything but b in the original formula

$y=\frac{1}{6} x+b\\70=\frac{1}{6}113+b\\420=113+6b\\307=6b\\\frac{307}{6}=b$

so now that we know our b and our m, we can plug those into the original equation to get our answer!

$y=\frac{1}{6}x+\frac{307}{6}$
