for In the given expression, calculate as indicated. Express your answer as a single polynomial in standard form. 4x^(3)-2x^(2)+9)-(6x^(2)-6x+5), what is the answer
Answer:
The polynomial in standard form is [tex]y = 14 + 6\cdot x - 8\cdot x^{2}+4\cdot x^{3}[/tex].

To simplify the expression 1/3 x (15+6),
we start by simplifying the addition inside the parentheses.
=15 + 6
= 21
Now, we can multiply the result by 1/3:
= 1/3 x 21
= 21/3
= 7
Therefore, 1/3 x (15+6) simplifies to 7.

What is the length of the side of the triangle opposite to theta if theta is equal to 30 degrees and the hypotenuse is 2 units
Answer:
1 unitStep-by-step explanation:
In a right angled triangle, the side opposite to the acute angle theta given is always the opposite side of the triangle and the longest side is the hypotenuse.
Given the angle theta in a triangle to be 30 degrees and the hypotenuse to be 2 units, to ge the opposite side, we will use the trig identity SOH in SOH, CAH, TOA
Sin(theta) = Opposite/Hypotenuse
Substitute the given parameters into the expression
sin30° = Opposite/2
cross multiply
Opposite = 2 * sin30°
Opposite = 2 * 0.5
Opposite = 1 unit
Hence the length of the side of the triangle opposite to theta is 1 unit.

In a box, there are black pens, red pens and green pens
the ratio of black pens to not black pens is 9:11
the ratio of green pens to not green pens is 3:5
fins the ratio of black pens to red pens to green pens
What do we know?
There are 9 black pens and 3 green pens.
What else do we know?
We know that 11 of the pens aren't black, and 5 of them aren't green.
Black pens (9) : red pens (6) : green pens (3)
How'd I get 6?
If 11 pens aren't black, they had to be green, but 5 of them weren't green. So, I subtracted 11 from 5 to get 6 red pens.
I hope that makes sense.
Final answer:
9:6:3

In a morning walk three persons step off together their steps measure 80cm,85cm and 90cm respectively. What is the minimum distance each should walk so that all can cover the same distance in complete steps?
Answer:
The minimum distance each should walk to cover the same distance is 12240 cm
Step-by-step explanation:
The minimum distance each should walk so that all can cover the same distance in complete steps is the same as the Lowest Common Multiple (LCM) of the three numbers, which is the least integer that is divisible by each of the three numbers.
To find the LCM, we will first find the lowest multiples of each of the numbers
80 ⇒ (2) × 2 × 2 × 2 × (5)
85 ⇒ 17 × (5)
90 ⇒ (2) × 3 × 3 × (5)
Note: in finding LCM, the numbers common to at least 2 (in bracket), out of the three terms is written just once.
∴ LCM = 2 × 2 x 2 × 2 × 3 × 3 × 5 × 17
= 16 x 9 x 85
= 12240 cm
Therefore, the minimum distance each should walk to cover the same distance is 12240 cm

Henry can paint a small house in 3 days, Ruby can paint a small house in 4 days, and Charlie can paint a small house in 5 days. How long will it take for Henry, Ruby and Charlie to paint one small house together? Give your answer as a fraction.
Answer:
So it will take them 1 day 6 hours and 39 minutes to paint one small house.
Step-by-step explanation:
Henry can paint 1 small house in 3 days so he can paint 1/3 or .3333 in a day
Ruby can paint 1 small house in 4 days so she can paint 1/4 or .25 in a day
Charlie can paint 1 small house in 5 days so he can paint 1/5 or .2 in a day
Together, that means they pain .3333 + .25 + .2 of a house per day. That's an daily rate of:
.3333 + .25 + .2 = .78333
The portion of the house they clean in x days is .78333x. We'd like to know how long it will take them to paint 100% or 1 of the house. So:
.78333x = 1 Divide each side by .78333
x = 1/.78333
x ≈ 1.277
Let's convert .277 to hours by multiplying by 24
.277 * 24 = 6.65
Let's convert .65 to minutes by multiplying by 60
.65 * 60 = 39
So it will take them 1 day 6 hours and 39 minutes to paint one small house.
Answer:
1.277 days
Step-by-step explanation:
H paint .3333 a day R paint .25 a day Charlie paint .2 a day
.3333 + .25 + .2 = .78333
x is number of days to paint.
.78333x = 1
x = 1/.78333 = 1.277
1.277 days

A bag of marbles contains 6 bluemarbles, 2 yeloow marbles, 4 red marbles, and 1 green marble. What is the [robability of reaching into the bag and selecting a yellow marble?
Answer:
The probability of picking a yellow marble is 2/13
Step-by-step explanation:
First of all, we need to know the total number of marbles that are in the bag. To do this, we will have to add up all the marble colors together.
This will give us 6 + 2 +4+ 1 = 13 marbles in total.
The next step is to find the number of yellow marbles in the bag.
We can get this from the question. There are 2 yellow marbles in the bag.
The probability of selecting a yellow marble can be obtained by dividing the number of yellow marbles by the total number of marbles in the bag
This will give us 2/13.
Therefore, the probability of picking a yellow marble is 2/13

Using the multiplication/product law of exponents, you can add the exponents up.
Answer:
3^10 and the law used would be the Product Rule for exponents.
Step-by-step explanation:
turning this question into an equation you would get:
3^8 * 3^2 = ?
The law you use in this situation is the product rule for exponents. If you have the same base number (in this case it is 3) with exponents and you are multiplying them, then you can add the exponent numbers and keep the base the same. This product rule looks like this:
A^x * A^y = A^(x+y)
Applying it to this question, you get
3^8 * 3^2 = 3^(8+2)
3^(8+2) is 3^10.
Therefore the simplified expression is 3^10.

Is it parrallel, perpendicular, or neither x=-3 y=3
Answer:
I think its neither because
Step-by-step explanation:
Parallel lines and their slopes are easy. Since slope is a measure of the angle of a line from the horizontal, and since parallel lines must have the same angle, then parallel lines have the same slope — and lines with the same slope are parallel. Perpendicular lines are a bit more complicated.
Answer:
perpendicular
Step-by-step explanation:
They form a 90 degree angle because one is vertical and the other is horizontal.
