An artifact originally had 16 grams of carbon-14 present. The decay model A = 16 e -0.0001211 describes the amount of carbon-14 present after t years. Use the mode
to determine how many grams of carbon-14 will be present in 9088 years
The amount of carbon-14 present in 9088 years will be approximately
grams.
The mass of Carbon-14 left according to the decay model after 9088 years will be; 5.3229 grams
The decay model is given as;
A = 16 e^ (-0.0001211t)Therefore, after 9088 years; in which case; t = 9088.
The amount of Carbon-14 that will be present is;
A = 16e^ (-0.0001211 × 9088)A = 16e^(-1.1005)A = 5.3229gramsRead more:

find the zeros of y=x^3-x^2-9x+9
with explanation
Answer:
So, we have the equation:
[tex]y=x^3-x^2-9x+9[/tex]
Usually, we have to do trial-by-error methods like using the Rational Root Theorem to factor cubic polynomials. However, while this may seem like a complicated cubic equation to factor, it has a simple trick to make it much easier!
We can actually factor this polynomial through Factoring by Grouping. With this method, we can factor a cubic polynomial. We split the equation into two parts, like this:
[tex]y=x^3-x^2-9x+9[/tex]
[tex]y=(x^3-x^2)+(-9x+9)[/tex]
Which can be simplified to:
[tex]y=(x^2)(x-1)+(-9)(x-1)[/tex]
We took out a factor of x^2 for the first term and a negative 9 for the second term. As we can see, we now have two terms that are the same:
(x - 1)
We can factor out the (x - 1) like this:
[tex]y=(x^2)(x-1)+(-9)(x-1)[/tex]
[tex]y=(x-1)(x^2-9)[/tex]
Now, this is not the most simplified form. See the x^2-9 term? We can use the Difference of Squares.
In general:
[tex]a^2-b^2=(a-b)(a+b)[/tex]
We have the expression:
[tex](x^2-9)=(x^2-3^2)[/tex]
[tex](x^2-3^2)=(x-3)(x+3)[/tex]
Therefore:
[tex]y=(x-1)(x^2-9)[/tex]
[tex]y=(x-1)(x-3)(x+3)[/tex]
Our fully factored form for y=x^3-x^2-9x+9 is:
[tex]y=(x-1)(x-3)(x+3)[/tex]

Step-by-step explanation:
what do we need to do ? find the 0 solutions for x ?
if that is the case, let's just do all the multiplication first :
(3/2)² × (2/3)⁴x² = x
9/4 × 16/81 x² = x
4/9 x² = x
4/9 x² - x = 0
4x² - 9x = 0
x × (4x - 9) = 0
so, one solution is obviously x = 0.
the second solution is
4x - 9 = 0
4x = 9
x = 9/4

find f(9) if f(x) = 4^x + 12
Answer:
I think its 262156
Step-by-step explanation:
Answer:
If f(x) = 4ˣ + 12, f(9) = 262156.
Step-by-step explanation:
f(x) = 4ˣ + 12
Substitute input x = 9.
f(9) = 4⁹ + 12
Evaluate 4 to the 9th power.
f(9) = 262144 + 12
Add 262144 and 12.
f(9) = 262156.

Which statement explains how to correct the error that was made?
O The subtraction property of equality should have been applied to move m to the other side of the equation.
O The multiplication property of equality should have been applied in the last step.
The division property of equality should have been used to divide by k instead of m.
O The square root property should have been applied to both complete sides of the equation instead of to select
variables.
Solving for v in the given equation is performed by making v the equation's
subject.
Response:The statement that describes where the error was made is option;
The square root property should have been applied to both complete sides of the equation instead of to select variables.Method for solving for v in the given equation;v can be solved for from the given expression as follows;
[tex]\displaystyle k = \mathbf{\frac{1}{2} \cdot m \cdot v^2}[/tex]
[tex]\displaystyle k \div m = \mathbf{\left(\frac{1}{2} \cdot m \cdot v^2 \right) \div m}[/tex]
[tex]\displaystyle \frac{k}{m} \times 2 = \left( \frac{1}{2} \cdot v^2 \right) \times 2[/tex]
[tex]\displaystyle \frac{2 \cdot k}{m}= \mathbf{v^2}[/tex]
Taking the square root of both sides of the equation gives;
[tex]\pm \sqrt{\displaystyle \frac{2 \cdot k}{m}} = \mathbf{\sqrt{v^2}}[/tex]
Therefore;
[tex]\displaystyle \pm \sqrt{\frac{2 \cdot k}{m} } = v[/tex]
Therefore, the error was made in the step, [tex]\displaystyle \pm \frac{2 \cdot \sqrt{k} }{m} = \sqrt{v^2}[/tex] , which is by
applying the square root property was applied to only some of the
variables on the left hand side of the equation, rather than the combined
expression on the left hand side of the equation.

A group of people were asked whether they prefer soup or salad for lunch.
The table shows the probabilities of the results
Let A represent having soup and B represent having salad for lunch.
Which statement is true?
A. Having soup and salad for lunch are independent events because P(A]B) = P(A) and P(BA) = P(B)
B. Having soup and salad for lunch are independent events because P(A]B) + P(A) and P(BA) + P(B)
C. Having soup and salad are not independent events because P(A]B) + P(A) and P(BA) + P(B)
D. Having soup and salad for lunch are not independent events because P(A]B) = P(A) and P(BA) = P(B)
Answer:
Having soup and salad for lunch are independent events because P(A/B)=P(A) and P(B/A) = P(B)

what number is six more than 1/3 of 90? step by step I have a test tomorrow and I don't know any math
Answer:
36
Step-by-step explanation:
First, just multiply 90 by 1/3. 90 is equal to 90/1 as any number divided by 1 is still equal to itself.
[tex]\frac{90}{1}*\frac{1}{3}=\frac{90*1}{1*3}=\frac{90}{3}[/tex]
Now, 90/3 is just 90 ÷ 3.
[tex]90 \div 3 = 30[/tex]
Finally, just add 6 to it.
[tex]30+6=36[/tex]
Answer:
36
Step-by-step explanation:
1/3 of 90 is 30
6 more is 30+6=36
