12) What is the degree of the resulting polynomial when a 3rd degree binomial is added to a 4th degree

1 answer:

7 0

Since adding polynomials doesn't change the degree (unless the two highest degree terms match and cancel each other out), the result will just be the degree of the highest degree polynomial.

In your case, the result will be a 4th degree polynomial.

Joanne's Dress Shop received an invoice dated July 25 for $1,400, with terms of 2/10, 1/15, n/60. On August 8, Joanne's Dress Sh

The actual amount that should be credited is $757.58.

Solution:

Given that,

2% Discount if paid in 10 days.

1% Discount if paid in 15 days, (but greater that 10 days)

Net due in 60 days.

That is,

$\bold{1400\times0.98 = 1372}$ will close the acount on days 1-10

$\bold{1400\times0.99 = 1386}$ will close the acount on days 11-15

And August 8 is Day 15 and falls under the 1% discount rule.

Therefore, we have to divide the partial payment by the complement of the discount rate.

$\bold{\Rightarrow\frac{750}{0.99} = 757.58}$ from the balance, and $\bold{1400.00 - 757.58 = 642.42}$ is due by day 60.

Answer:

m∠B < m∠A < m∠C

Step-by-step explanation:

We can work with the triangle inequality to find that the side measures form a triangle when n > 5/4. For the given value of n ≥ 4, we don't need to be concerned with whether a triangle is formed or not.

For n = 4, the side lengths are ...

a = 2(4) = 8

b = (4) +3 = 7

c = 3(4) -2 = 10

The longest side is opposite the largest angle, so the ordering of angles is ...

m∠B < m∠A < m∠C

_____

The triangle inequality requires all of these inequalities be true:

a+b > c ⇒ 3n+3 > 3n-2 . . . always true
b+c > a ⇒ 4n+1 > 2n ⇒ n > -1/2
c+a > b ⇒ 5n-2 > n+3 ⇒ n > 5/4

That will be the case for n > 5/4. The attached graph shows the sides and angles keep the same order for n > 3.

4. If DF = 9x - 39, find EF. Help I’m so confused!!!!

topjm [15]

Answer:

EF =58

Step-by-step explanation:

from the illustration,

EF =DF - DE

given that DF =9x-39 , DE =47 EF=3x +10

substitute them into the formula,

3x +10=9x-39 - 47

solving for x

3x +10 =9x -86

grouping like terms

3x - 9x =-86 -10

-6x=-96

dividing through by -6

 $\frac{ - 6x}{ - 6} = \frac{ - 96}{ - 6}$ 

 $x = \frac{96}{6}$ 

 $x = 16$ 

but EF=3x+10

substitute x=16 into it to get the EF

EF= 3(16)+10

EF=48+10

EF=58
