g(x) is a polynomial that has a leading coefficient of 3, and the following roots -1,1,2. Write g(x) in standard form
The standard form of the polynomial is written as:
p(x) = 3*x^3 - 6*x^2 - 3x + 6
How to write the polynomial in standard form?We know that a polynomial of degree N is with the zeros {x₁, x₂, ...} and a leading coefficient a can be written as:
p(x) = a*(x - x₁)*(x - x₂)*...*(x - xₙ)
In this case, we know that the leading coefficient is 3, and the zeros of the polynomial are {-1, 1, 2}
Then we can write:
p(x) = 3*(x + 1)*(x - 1)*(x - 2)
Now we need to expand that, we will get:
p(x) = 3*(x + 1)*(x - 1)*(x - 2)
p(x) = 3*(x^2 + 1*x + x*(-1) + 1*(-1))*(x - 2)
p(x) = 3*(x^2 - 1)*(x - 2)
p(x) = 3*(x^3 + x^2*(-2) - x + 2)
p(x) = 3*x^3 - 6*x^2 - 3x + 6
That is the polynomial in standard form.

one isotope of chromium has a half life of 18 hours. How long does it take 100 grams to decay to 20 grams?
Answer:
41.79 hours
Step-by-step explanation:
The Half-time Decay Formula: [tex]N=N_0(\frac{1}{2})^\frac{t}{d}[/tex]
Where [tex]N_0[/tex] is the original number, and t = time, and d = time it takes to half
18 would be d
100 would be [tex]N_0[/tex]
and 20 would be N
[tex]20=100(\frac{1}{2})^\frac{t}{18}[/tex]
[tex]0.2=(\frac{1}{2})^\frac{t}{18}[/tex]
[tex]log_\frac{1}{2}0.2=\frac{t}{18}[/tex]
[tex]18* log_\frac{1}{2}0.2=t[/tex]
[tex]18* \frac{log_{10}0.2}{log_{10}\frac{1}{2}}=t[/tex]
= 41.79470571
The hypotenuse of a right triangle is 30 inches. With one of the sides being 18 inches. Find the missing side length. Round to the nearest hundredth if necessary
Answer:
24 inches
Step-by-step explanation:
We can find different sides of a right angle triangle using Pythagorean theorem: [tex]c^2 = a^2+b^2[/tex], where [tex]c[/tex] is the hypotenuse and [tex]a[/tex] and [tex]b[/tex] are the other sides.
Therefore, we can re-arrange the equation for one of the other sides.
[tex]c^2-b^2=a^2[/tex].
Since we know these two sides all we have to do is put them into the equation:
[tex](30)^2-(18)^2=a^2[/tex]
[tex]a^2 = 576\\a= 24[/tex]
Therefore, the missing side is 24 inches.

The sum of 85 + w is less than or equal to 6 multiplied by y.
A. 85 + w ≤ 6y
B. 85 + w ≥ 6y
C. 6 x y ≤ 85 + w
D. 85 + w ≠ 6y
Given:
The sum of 85 + w is less than or equal to 6 multiplied by y.
To find:
The inequality for the given situation.
Solution:
We know that,
The sum of 85 and w means "85+w".
Less than or equal means "≤".
6 multiplied by y means "6y".
So, the inequality for the statement "the sum of 85 + w is less than or equal to 6 multiplied by y", is:
[tex]85+w\leq 6y[/tex]
Therefore, the correct option is A.

z=31°
stay safe healthy and happy.Answer:
31 degrees = x
Step-by-step explanation:
a triangle's sum is 180 degrees
let's form an equation that allows us to work backwards and find this
add the other two angle measures to x and let the sum be 180
32+117+x=180
31 is the difference and therefore the missing angle measure

3. My sister is 12 years older than lam Our combined age is half the age of our
grandfather. Our grandfather is 68 years old. How old am
Answer:
11
Step-by-step explanation:
First, write an equation to represent the situation.
34 = 2a + 12
This equation works because your combined age is half of 68, so 34. If your age is a, then yours sister's age is a + 12. if you add your age to your sister's, you get 2a + 12.
Now just solve for a.
34 = 2a + 12
First, subtract 12 from both sides.
22 = 2a
Then divide both sides by 2.
11 = a
So you are 11 years old. If you need to check your work, your age (11) plus your sister's age (11 + 12, which is 23) is 34, which is half of your grandfather's age.
Find the length of ST. Round your answer to the nearest tenth of an inch.
Answer:
7.1
Step-by-step explanation:
Once again we can use trig ratios to solve for ST
First we must recall the trig function
Sin = Opposite over Hypotenuse
Cos = Adjacent over Hypotenuse
Tan = Opposite over Adjacent
We are given the measure of an angle and the length of the hypotenuse
Of the given angle we need to find the adjacent side length
When working with the hypotenuse and adjacent we use trig function cosine
That being said we want to create an equation ( remember cos = adjacent over hypotenuse ) ( let ST = x)
[tex]cos(42)=\frac{x}{9.5}[/tex]
now we solve for x
Step 1 multiply each side by 9.5
[tex]cos(42)*9.5=9.5cos(42)=7.059875842\\\frac{x}{9.5} *9.5=x[/tex]
we're left with x = 7.059875842
Finally we round to the nearest tenth and get that the answer is 7.1

1. Are the two expressions below
equivalent
25x + 20y = 5x(5+4y)
Answer:
No.
Step-by-step explanation:
25x + 20y = 5x(5 + 4y)
Distribute the 5x inside the (5 + 4y).
5x * 5 = 25x
5x * 4y = 20xy
25x + 20y ≠ 25 + 20xy, so the two expressions below are not equal.
