Answer:
a) y = (x - 3)²
b) y = x² - 4
c) y = (x + 2)²
d) y = x² + 5
e) y = (x + 6)² - 7
f) y = (x - 2)² + 5
Step-by-step explanation:
Parent equation: y = x²
Transformed equation: y = (x - h)² + k
h translates the parabola horizontally
If h > 0 then the translation is h units to the right.
If h < 0 then the translation is h units to the left.
If h = 0 then there is no horizontal translation.
k translates the parabola vertically
If k > 0 then the translation is k units up.
If k < 0 then the translation is k units down.
If k = 0 then there is no vertical translation.
a) The parabola moves 3 units to the right:
⇒ y = (x - 3)² + 0
⇒ y = (x - 3)²
b) The parabola moves 4 units down:
⇒ y = (x - 0)² - 4
⇒ y = x² - 4
c) The parabola moves 2 units left:
⇒ y = (x + 2)² + 0
⇒ y = (x + 2)²
d) The parabola moves 5 units up:
⇒ y = (x - 0)² + 5
⇒ y = x² + 5
e) The parabola moves 7 units down and 6 units left:
⇒ y = (x + 6)² - 7
f) The parabola moves 2 units right and 5 units up:
⇒ y = (x - 2)² + 5

It is predicted that by 2050, there will be 10^10 people living on Earth. At that time, it is predicted there will be approximately 10^12 trees. How many trees will there be for each person?
Answers
Answer:
100 trees per person
Step-by-step explanation:
10^12 trees / 10^10 persons = 10^(12-10) = 10^2 trees/person
Answer:
Step-by-step explanation:
Givens
There are 10^12 trees
There are 10^10 people
Solution
Number of trees / person = Number of trees / Number of people = 10^12/10^10= 10^(12 - 10) = 10^2 = 100
There will be 100 trees / every person on the planet.
The Sausage Hut is looking at a new sausage system with an installed cost of $330,000. This cost will be depreciated straight-line to zero over the project's three-year life, at the end of which the sausage system is estimated to have zero value. The project has no impact on net working capital. Each year during its three year life, the new system will increase the firm’s Sales by $455,000 and its Operating Cash Flow by $123,300.
If the tax rate is 30 percent and the discount rate is 9 percent, what is the NPV of this project?
Group of answer choices
-111,524
- $17,891
$19,405
$35,389
$1,136,217
Answers
Based on the net cashflow over the three year life, the NPV that Sausage Hut will realize is -$17,891.
What is the Net Present Value?First find the present value of the increased cashflows. As it is a constant amount of $123,300, we can treat it as an annuity.
Present value = Amount x (Present value of annuity interest factor, 9%, 3 years)
= 123,300 x 2.5313
= $312,109.29
The net present value is:
= Present value of cashflows - Amount invested
= 312,109.29 - 330,000
= -$17,890.71
= -$17,891.
In conclusion, option B is correct.

Answers
Answer:
x^2 – 4 = 0 AND 4x^2 = 16

a) x^2 – 4 = 0 --> (x + 2)(x - 2)=0 --> x= -2 AND x= +2
b) x^2 = -4 doesn't have any solution in the real numbers.
c) 3x^2 +12 = 0 -->(divide by 3)--> x^2 +4 =0 ---> x^2 = -4 as b)
d) 4x^2 = 16 -->(divide by 4)--> x^2 = 4 --> x^2 -4 = 0 as a)
e) 2(x -2)^2 =0 -->(divide by 2)--> (x-2)^2 =0 --> one solution that is x=+2
A balloon archway has been ordered for decorating the high school gym for a 1950's
style prom. The archway will contain 417 balloons, each holding 1.1 liters of helium.
Each balloon has a mass of 0.027 grams when empty, and all the string and fixings
that hold the balloons together total another 36 grams. If helium has a density of
0.1785 grams per liter, what is the mass of the entire archway.
Answers
We will see that the total mass of the entire archway is M = 129.1578g
What is the mass of the entire archway?We know that each ballon weighs 0.027 grams for the plastic.
Now, we also need to remember the relation:
mass = density*volume.
Here, the density of helium is 0.1785 g/L
And the volume of each ballon is 1.1 L, then the mass of helium in each ballon is:
m = (0.1785 g/L)*(1.1 L) = 0.1964 g
Then the total mass of each ballon is:
M = 0.1964 g + 0.027g = 0.2234g
And there are 417 ballons, so the total mass (also adding the 36 grams for the strings) is:
Mass = 417*0.2234g + 36g = 129.1578g

The GRE is an entrance exam that many students are required to take in order to apply to graduate school. In 2014, the combined scores for the Verbal and Quantitative sections were approximately normally distributed with a mean of 310 and a standard deviation of 12.
What is the probability that a randomly selected score is greater than 334? Write your answer as a decimal
Answers
Using the normal distribution, it is found that there is a 0.0228 probability that a randomly selected score is greater than 334.
Normal Probability DistributionThe z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.In this problem, the mean and the standard deviation are, respectively, given by [tex]\mu = 310, \sigma = 12[/tex]
The probability that a randomly selected score is greater than 334 is one subtracted by the p-value of Z when X = 334, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{334 - 310}{12}[/tex]
Z = 2
Z = 2 has a p-value of 0.9772
1 - 0.9772 = 0.0228.
0.0228 probability that a randomly selected score is greater than 334.

In how many ways can the word "calculus" be arrange so that two L's do not come together?
Answers
Count the total number of permutations of the word "calculus": there are 8 letters, hence 8! = 40,320 total permutations.
Count the number of permutations in which the two L's occur next to each other. Effectively we're now talking about words consisting of 7 letters, of which there are 7! = 5,040.
It follows that there are
8! - 7! = 35,280
words in which two L's do not appear next to each other.

Find the axis of symmetry and
the
vertex of the graph of y = 3x^2
-18x + 17
Answers
Answer:
vertex: (3, -10)
axis of symmetry: x = 3
Step-by-step explanation:
Vertex form of a quadratic equation: [tex]y=a(x-h)^2+k[/tex]
(where (h, k) is the vertex)
Rewrite the given equation in vertex form by completing the square.
Given equation:
[tex]y=3x^2-18x+17[/tex]
Add 10 to both sides:
[tex]y+10=3x^2-18x+27[/tex]
Factor RHS:
[tex]y+10=3(x^2-6x+9)[/tex]
[tex]y+10=3(x-3)^2[/tex]
Subtract 10 from both sides:
[tex]y=3(x-3)^2-10[/tex]
Therefore, the vertex is (3, -10)
The axis of symmetry is the x-value of the vertex.
Therefore, the axis of symmetry is x = 3.
Answer:
Axis of symmetry: x = 3
Vertex: (3, -10)
Step-by-step explanation:
y = 3x² - 18x + 17
Axis of symmetry formula: x = [tex]\sf{\frac{-b}{2a}}[/tex]
a = 3b = -18[tex]\sf x={\frac{-b}{2a}}\implies \textsf{Substitute -18 for b and 3 for a}\\\\\sf\ x={\frac{-(-18)}{2(3)}}\implies\textsf{multiplying 2 negatives makes a positive}\\\\\sf\ x={\frac{18}{6}}\implies \textsf{divide}\\\\\ \boxed{\sf x=3}\implies \textsf{axis of symmetry}[/tex]
Now, substitute 3 for x in your original equation to find the value of y:
y = 3x² - 18x + 17
y = 3(3)² - 18(3) + 17 <== exponents first
y = 3(9) - 54 + 17 <== multiply
y = 27 - 54 + 17 <== subtract
y = -27 + 17 <== add
y = -10
Vertex: (3, -10)
