Write an expression that represents the height of a tree that began at 6 feet an increases by 2 feet per year. Let y represent the number of years
Answers
Answer:
Yes.
Step-by-step explanation:
The expression 2y + 6 could be used to denote the tree's height.
What is an expression?A number, a variable, or a mixture of numbers and variables, along with operation symbols, make up an expression. Two expressions joined by an equal sign form an equation.
Given, the height of a tree that began at 6 feet and increases by 2 feet per year. Let y represent the number of years
Expression = 2y + 6
Since the height of the tree starts at 6 feet thus positive 6 would be constant and it increases by 2 feet every year thus 2 would be the multiple of the variable that is y.
therefore, an Expression that represents the height of the tree would be 2y + 6.

If
f(x) = ax + 6,
where a is a constant, and f(2) = 8, calculate a.
Provide your answer below:
Answers
Answer:
1
Step-by-step explanation:
f(x) = a(2) + 6 = 2a + 6
Given f(2) = 8
so 2a + 6 = 8
2a = 8 - 6 = 2
so a = 1

The graph of f(x) shown below
Answers
Answer:
C
Step-by-step explanation:
the "-" sign can't be true, because that would have turned the whole graph of x² upside-down. but it is not.
so, we need a positive sign for the x term.
and the whole graph is shifted to the right. so the functional value of x of F(x) is now the same that happened "earlier" (for smaller x) with G(x). so, the argument "x" is now reduced (by 3 units, as the graph is shifted right by 3 units) in the calculation compared to the original G(x) calculation.
therefore, the ...(x-3)... expression is right.
so, positive sign and "(x-3)" is only in C.

A piñata is a container filled with candy and is broke by hitting it with a stick. The probability that Amanda will break a piñata on her first his is 0.58. She will continue to hit the piñata until it breaks. If she does not break the piñata on a particular hit, the piñata is weakened and the probability that she will break it on the next hit is 0.14 greater than the probability on the previous hit. For example, if the piñata does not break on the first hit, the probability that it will break on the second hit is 0.72 (found by 0.58 + 0.14 = 0.72). Calculate the probability that Amanda does not break the piñata on the first hit and does break the piñata on the second hit
Answers
Answer:
0.3024
Step-by-step explanation:
Given the following :
Probability of breaking pinata on first hit = 0.58;
P(first hit break) = 0.58
P(does not break on first hit) = 1 - p(first hit break) = 1 - 0.58 = 0.42
P(2nd hit break) = p(first hit break) + 0.14 = 0.58 + 0.14 = 0.72
Hence, Calculate the probability that Amanda does not break the piñata on the first hit and does break the piñata on the second hit
P(does not break on first hit) * p(2nd hit break)
0.42 * 0.72 = 0.3024

Radioactive isotope Carbon-14 decays at a rate proportional to the amount present. If the decay rate is 12.10% per thousand years and the current mass is 135.2 mg, what will the mass be 2.2 thousand years from now?
Answers
Using an exponential function, it is found that the mass 2.2 thousand years from now will be of 103.6 mg.
What is an exponential function?It is modeled by:
[tex]A(t) = A(0)e^{-k\frac{t}{n}}[/tex]
In which:
A(0) is the initial value.k is the decay rate per n years.In this problem:
The decay rate is 12.10% per thousand years, hence k = 0.121, n = 1000.The current mass is 135.2 mg, hence A(0) = 135.2.Then:
[tex]A(t) = A(0)e^{-k\frac{t}{n}}[/tex]
[tex]A(t) = 135.2e^{-0.121\frac{t}{1000}}[/tex]
The mass 2.2 thousand years from now will be given by:
[tex]A(2200) = 135.2e^{-0.121\frac{2200}{1000}} = 103.6[/tex]
The mass 2.2 thousand years from now will be of 103.6 mg.

Answers
The two numbers on the dot plot that will have the same number of dots would be: B. 8.0 and 8.2.
What is a Dot Plot?A dot plot can be described as a simple form of data visualization that shows the frequency at which each data points in the data set occurs, which are plotted as dots.
The data set of the measures of the fossils taken by the paleontologist include the following data points and the frequency at which they occur and how they are represented on a dot plot:
7.8 - 5 times (5 dots)7.9 - 6 times (6 dots)8.0 - 0 times (0 dot)8.1 - 3 times (3 dots)8.2 - 1 times (1 dot)We are told that the paleontologist found two errors, where a length of two fossils that measure 7.9 are recorded as 8.1 and 8.2.
Therefore, if the correct measures are used to draft a new dot plot, we would have the following data points and number of dots representing the correct frequency of each measures:
7.8 - 5 times (5 dots)7.9 - 8 times (8 dots)8.0 - 0 times (0 dot)8.1 - 2 times (2 dots)8.2 - 0 times (0 dot)Therefore, the two numbers on the dot plot that will have the same number of dots would be: B. 8.0 and 8.2.
