Answer:
p(x) = 2*x^4 - 2*x^3 - 52*x^2 - 48*x
Step-by-step explanation:
For a polynomial p(x) with leading coefficient A, and zeros: {x₁, x₂, ...,xₙ}
The polynomial can be written in the factored form as:
P(x) = A*(x - x₁)*(x - x₂)*...*(x - xₙ)
In this case, we know:
Leading coefficient equal to 2, and the zeros are: 0, -1, 6, and -4
Then the polynomial can be written as:
p(x) = 2*(x - 0)*(x - (-1))*(x - 6)*(x - (-4))
p(x) = 2*x*(x + 1)*(x - 6)*(x + 4)
The wanted polynomial is this one, and we can expand it to get:
p(x) = (2*x^2 + 2*x)*(x - 6)*(x + 4)
p(x) = (2*x^3 - 12*x^2 + 2*x^2 - 12*x)*(x + 4)
p(x) = (2*x^3 - 10*x^2 - 12*x)*(x + 4)
p(x) = 2*x^4 + 8*x^3 - 10*x^3 - 40*x^2 - 12*x^2 - 48*x
p(x) = 2*x^4 - 2*x^3 - 52*x^2 - 48*x
pLEASE HELP ME ASAP FOR 9 AND 10
Answer:
9)
x^2 + 2x + 1 = (x + 1)^2
10)
x^2 - 6x + 9 = (x - 3)^2
Step-by-step explanation:
To complete the square, add the square of half of the x-term coefficient.
Then use the factoring of a perfect square trinomial.
a^2 + 2ab + b^2 = (a + b)^2
a^2 - 2ab + b^2 = (a - b)^2
9)
x^2 + 2x + 1 = (x + 1)^2
10)
x^2 - 6x + 9 = (x - 3)^2

ratios that are equivalent to 9:6.
Answer:
3:2
Step-by-step explanation:
Answer:
3:2 , 18:12 , 27:18
Step-by-step explanation:
There are endless ratios that are equal to 9:6.
Such as 3:2 , 18:12 , and 27:18.
To find equivalent ratios, simply divide or multiply the two numbers in the ratio by the same number.
For example, the ratio is 9:6.
9/3 = 3
And, 6/3 =2
So therefore an equivalent ratio is 3:2.

379.00 - 15.00 + 154.00 x 3 + 65.00 + 13.00 = 904
0.55 x 63 = 34.65
34.65 + 904 = 938.65
Answer:
Your answer is D
Step-by-step explanation:
because 379-15+154x3+65+13+0.55x63=938.65

Felix puts 6000 into saving bonds that pay a simple interest rate of 4.4 how much money will the bonds be worth at the end of 6 years
Answer:
$7,584
Step-by-step explanation:
The computation of the amount worth at the end of 6 years is shown below:
As we know that
SImple interest = Principal amount × rate of interest × time period
= $6,000 × 4.4% × 6
= $1,584
Now the amount at the end of 6 years is
= Principal amount + simple interest
= $6,000 + $1,584
= $7,584
Hence, the amount would be $7,584

can someone please help me is the answer-8
Answer:
h(-8)=-8
Step-by-step explanation:
Since we are finding h(-8), we plug -8 into the equation:
h(-8)=((-8)²+3(-8))/(4(-8)+27)
h(-8)=(64-24)/(-32+27)
h(-8)=40/-5
h(-8)=-8
Therefore, h(-8)=-8, which means your answer is correct!
After 2014 the sales of new cell phones without cameras began declining. The number of people y (in thousands) who bought a cell phone without a camera can be estimated by the equation y=-30x+240, where x is the number of years after 2014
Answer:
60,000 people
Step-by-step explanation:
Given the number of people y (in thousands) who bought a cell phone without a camera can be estimated by the equation y=-30x+240,
x is the number of years after 2014
We can find the number of people that bought the cell phone in 2020. In year 2020, that will be after 6years
Substitute x = 6 into the expression
y=-30x+240
y=-30(6)+240,=
y = -180 + 240
y = 60
Since y is in thousands, hence the the number of people that have bought the cell phone by 2020 is 60,000 people

Theo has x beach toys. He shares them with 6 other friends. Each of them got 4 beach toys. Find x. Show all work
Answer:
24 beach toys
Step-by-step explanation:
We don't know how many beach toys Theo has, but we know that 6 of his friends each got 4 toys. The equation could be set up as x/6 = y, where x is equal to the total amount of toys Theo had, and y is equal to the amount of toys each friend received. We know that y = 4, so now you could say x/6 = 4, and now using opposite operations, 6 × 4 = 24, hence Theo had 24 toys.

firstly u can take the value of x=3 then put the value of x in equation..then u will get y = 0 so from this equation u get this(3,0)
then do same thing take value x = 6 and then u will get the value of y = -1 therefore u will get (6,-1)
Now plot these two points (3,0) and (6,-1) on graph..
Hope it helps u..!!
