Answer:
x = 3/2 + root(3)/2 or x = 3/2 - root(3)/2
In vertex form the equation is y = (x - 3/2)^2 + 3/4
Step-by-step explanation:
y = x^2 - 3x + 3
y = x^2 - 3x + 9/4 - 9/4 + 3
y = (x - 3/2)^2 + 3/4
I think you want to find the roots to the equation, right?
so
y = (x - 3/2)^2 + 3/4 = 0
(x - 3/2)^2 = -3/4
x - 3/2 = root(-3/4)
x = 3/2 + root(3)/2 or x = 3/2 - root(3)/2
Caleb is a junior at JA Enterprise High School and plays rugby on the school team. He has a part-time job at a local fast-food restaurant and works 20 hours a week for $7.60 an hour. His gross monthly income is $608.00, and his take-home pay is $501.64. In his spare time, Caleb walks a dog belonging to an elderly neighbor. He earns an additional $40 per month for that chore. What is Caleb's net monthly income? Remember net income is your take home pay.
Answer:
$541.64
Step-by-step explanation:
Caleb's take Home Pay from the Restaurant =$501.64
He earns an additional $40 per month for dog-walking.
Therefore,
Caleb's net monthly income =$501.64+40 =$541.64
Final answer:
Caleb's net monthly income is $541.64 after factoring in his take-home pay and additional earnings.
Explanation:
Caleb's net monthly income is calculated by subtracting his take-home pay from his additional earnings from walking the dog:
Caleb's take-home pay = $501.64
Additional earnings from walking the dog = $40
Net income = Take-home pay + additional earnings = $501.64 + $40 = $541.64

To find the surface area of the triangular prism, you need to find the area of all the sides and add them together. The two triangular bases have already been established to have an area of 3 square units each, so together they have an area of 6 units. Two of the rectangular sides have dimensions of 3.5 by 2.5 units, while one has dimensions 3.5 by 3 units. Adding all of this together, you get a total of 34 square inches, or option e.

What is the distance from the origin to point A graphed on the complex plane below? On a coordinate plane, Point A is at (negative 3, negative 2). StartRoot 5 EndRoot StartRoot 13 EndRoot 9 13
Answer:
b on edge
Step-by-step explanation:
The distance between the origin and point A is √13.
How to find the distance?
We know that the distance between two points (a, b) and (c, d) is:
[tex]D = \sqrt{(a - c)^2 + (b - d)^2}[/tex]
Here we want to find the distance between the origin, (0, 0), and the point A, which has coordinates (-3, -2).
Using the above formula we will get:
[tex]D = \sqrt{(-2 - 0)^2 + (-3 - 0)^2} = \sqrt{4 + 9} = \sqrt{13}[/tex]
The distance between the origin and point A is √13.

A person places $5540 in an investment account earning an annual rate of 2.5%,
compounded continuously. Using the formula V = Pent, where V is the value of the
account in t years, P is the principal initially invested, e is the base of a natural
logarithm, and ris the rate of interest, determine the amount of money, to the
nearest cent, in the account after 20 years.
Answer:
$9,133.92
Step-by-step explanation:
V = P*e^(rt)
V = $5540 * e ^ (0.025*20)
V = 5540 * e^(0.5)
V = 5540 * 1.648721
V = $9,133.9158
about $9,133.92
Final answer:
The amount of money in the account after 20 years with continuous compounding at an annual rate of 2.5% is approximately $9138.13.
Explanation:
To calculate the amount of money in an investment account after 20 years with continuous compounding, we use the formula V = Pe^rt, where:
P is the principal amount ($5540),
e is the base of the natural logarithms (approximately 2.71828),
r is the annual interest rate (2.5% or 0.025 as a decimal), and
t is the number of years the money is invested (20 years).
Plugging these values into the formula, we get:
V = $5540 × e^(0.025 × 20)
Using a calculator with the capability to compute e raised to a power, we find:
V ≈ $5540 × 2.71828^0.5
V ≈ $5540 × 1.64872
V ≈ $9138.13
Hence, the value of the investment after 20 years, to the nearest cent, is approximately $9138.13.

Answer:
3.2
Step-by-step explanation:
First, you have to arrange them in proper numerical order (least to greatest).
84, 88,90,92,96
Next, find the mean by adding them all up and dividing them by 5.
84 + 88 + 90 + 92 + 96 = 450
450 divide by 5 equals 90.
Now, that we have our mean, we have to subtract it from each of the numbers in the data set. Remember this is absolute so there is no negatives.
84 - 90 = 6
88 - 90 = 2
90 - 90 = 0
92 - 90 =2
96 - 90 = 6
Next, line them up again.
2,2,6,6
Find the mean of them:
2 + 2 + 6 + 6 = 16
16 divided by 4 is 4.
Therefore, our answer would be the MAD is 4.0

?/27= 8/9
Answer: 24/27 = 8/9
When you divide 27÷3 you get 9. 24÷3=8 therefore 24/27 = 8/9
8/9 = 16/18 = 24/27 = 32/36
Answer:
24/27
Step-by-step explanation:
First you would need to find the common denominator.
Or you can divide 27 from 9 which would get you 3. That will be our number to get our missing number. So you would multiply 8 and 3 which gets you 24.

A section of a deck is shaped like a trapezoid. For this section, the length of one base is 53 feet, and the length of the other base is 46 feet. The height is 16 feet. What is the area of this section of the deck?
Answer:
792 ft²
Step-by-step explanation:
The formula for area of a trapezoid is A = [tex]\frac{a+b}{2}[/tex] * h, where a = length of base (a) and b = length of base (b) and h = height of trapezoid.
If we plug the shown values, the formula becomes
[tex]\frac{53 + 46}{2}[/tex] * 16
This simplifies to 49.5 * 16, which equals 792. The answer with units is 792 ft².

60.2 rounded to the nearest hundredth
To round 60.2 to the nearest hundredth, we need to look at the digit in the thousandth place, which is the second digit after the decimal point. If this digit is 5 or greater, we'll round up, and if it's less than 5, we'll round down. In this case, the digit in the thousandth place is 2, which is less than 5. So, when rounding 60.2 to the nearest hundredth, we round down to 60.20.

Solve for x. *
(5x + 13)
(9x - 31)
Answer:
x=11
Step-by-step explanation:
5x+13=9x-31
subtract 9 from both sides.
-4x+13=-31
you want to isolate the x value so subtract 13 from both sides.
-4x=-44
now divide both sides by -4.
x=11
The solution for the variable x for given the equation (5x + 13) = (9x - 31) is equal to x = 11.
For the equation (5x + 13) = (9x - 31)
Expand the equation: 5x + 13 = 9x - 31
Combine like terms: 13 = 4x - 31
Isolate x: 4x = 44, x = 11
Therefore, the value of the variable x in the given equation is x = 11.
The above question is incomplete, the complete question is:
Solve for x.

Answer:
vertex form
Step-by-step explanation:
y= -3(x-5)^2+7
This equation is written in vertex form
y = a(x-h)^2 +k
The vertex is (h,k)
Answer:
This equation is in vertex form.
Vertex form means that for a quadratic equation, the format is as shown:
y= ±a(b(x-h))²+k. This means that this equation will give you the vertex point directly from the equation.

George and Cameron went on a bicycle trip they took a bus to the starting point they bought the rest they traveled 350 km in total and they bite 80 km more than they were biased how many kilometers are they travel by bike
Answer:
215
Step-by-step explanation:
We assume that the "starting point" is the starting point for the entire trip, including bus travel.
If B is distance traveled by Bus, and "b" is distance traveled by bike, then we seem to have ...
B + b = 350
b -B = 80
Adding these two equations gives ...
2b = 430
b = 215
They traveled 215 km by bike.
