Answer:
A. 4x¹² + 9x⁷ + 3x³ -x
Step-by-step explanation:
Hi!
<em>==================================================================</em>
To write a polynomial in descending order, we write the terms with higher degrees, or exponents, first.
3x³ + 9x⁷ -x + 4x¹²
4x¹² has the highest degree, so it is written as the first term.
⇒4x¹²
9x⁷ has the next highest degree, so it is written next.
⇒4x¹² + 9x⁷
3x³ has the next highest degree, so it is written next.
⇒4x¹² + 9x⁷ + 3x³
-x has the lowest degree, so it is written last.
⇒4x¹² + 9x⁷ + 3x³ -x
<u>4x¹² + 9x⁷ + 3x³ -x</u>

Independent variable = $20
dependent variable = $0.05 cents per min
y = total month cost
x = month minutes used
y = 20 + 0.05x
Start with with original price and find 30% of that price:
30% of 810: (0.30)(810) = 243
Now take that 30% away:
810 - 243 = 567
That's the sale price: $567
Find 30% of the sale price:
30% of 567: (0.30)(567) = 170.10
Now add that 30% on to the sale price:
567 + 1701.0 = 737.10
The final price described is $737.10.
Now we need to relate that final price to the original price:
737.10 ÷ 810 = 0.91
This means that the final price is 91% of the original price.

Answer:
v = 2√2i -2√2j
Step-by-step explanation:
v = ||v||·cos(θ)i +||v||·sin(θ)j
v = 4cos(315°)i +4sin(315°)j . . . . . . fill in the numbers
v = 2√2i -2√2j . . . . . . . . . . . . . . . put in desired form
