-3x^2+33=48x complete the square
The complete square form of - 3x² + 33 = 48x is [x + 8]² = 75
Completing the square:
To do this, we add and subtract a constant term to the quadratic expression to make it a perfect square.
In this case, we use the formula x² + 2bx + b² = (x + b)² to rewrite the quadratic expression as a perfect square trinomial, and then we solved for the variable by isolating the squared term and taking the square root.
Here we have
- 3x² + 33 = 48x
Keep 'x' terms on one side and constant terms sides on another side
=> - 3x² - 48x = - 33
Divide by - 3 on both sides
=> -3(x² + 4x)/3 = - 33/3
=> x² + 16x = 11
Take half of the 'x' term and square it and add on both sides
=> x² + 2(8x) (x) + (8)² = 11 + (8)²
Which is in the form of x² + 2bx + b² = (x + b)²
=> [x + 8]² = 75
Therefore,
The complete square form of - 3x² + 33 = 48x is [x + 8]² = 75

You would like to have $20,000 to use a down payment for a home in five years by making regular, end-of-month deposits into an annuity that pays 6% interest compounded monthly.
How much should you deposit each month?
Round your answer to the nearest cent. Do not include the dollar sign in the answer box below.
The calculation of this can be done by first determining the future value of the monthly payments of $327.50
The future value of an annuity can be determined using a financial calculator, mathematical formula, or spreadsheet software. The future value of an annuity is calculated by multiplying the periodic payment amount by the future value factor,
which is based on the number of payments and the interest rate.For example, suppose we want to know the future value of a $500 end-of-month deposit into an annuity that pays 6% interest compounded monthly for five years.
The future value factor for 60 periods at 0.5 percent per month is 80.9747, which can be multiplied by the monthly deposit amount to find the future value of the annuity.500 × 80.9747 = 40,487.35
This means that a $500 end-of-month deposit into an annuity paying 6% interest compounded monthly for five years will have a future value of $40,487.35.
Therefore, to accumulate a $20,000 down payment for a home in five years, you would need to deposit $327.50 per month into the annuity.
for 60 months using the formula and then solving for the monthly payment amount where FV = $20,000 and n = 60, r = 0.5%.FV = PMT [(1 + r)n – 1] / r$20,000 = PMT [(1 + 0.005)60 – 1] / 0.005PMT = $327.50 (rounded to the nearest cent).

The categorical data, in this case, refers to information that can be sorted into specific categories or groups. Among the options provided, hair color would be considered categorical data.Option c is correct
Hair color falls into distinct categories such as blonde, brown, black, red, or other variations. It is a qualitative characteristic that cannot be measured on a numerical scale.On the other hand, the other options can be classified as numerical data.
The number of siblings (option A) and age (option B) are both quantitative variables that can be represented numerically. They can be counted or measured using specific numerical values. Similarly, height (option D) is a quantitative measurement that can be expressed using numbers or units of length.

D. (-5, -2), (-7, 0), (-4, 1)
Answer:

Step-by-step explanation:
The following transformation is applied:
\((x,y) \rightarrow (y + 2, -x - 4)\)
To find the range:
We apply the transformation to the points in the domain. Thus:
\((1,-4) \rightarrow (-4 + 2, -1 - 4) = (-2, -5)\)
\((3,-2) \rightarrow (-2 + 2, -3 - 4) = (0, -7)\)
\((0,-1) \rightarrow (-1 + 2, 0 - 4) = (1, -4)\)

The 17th term is
Answer:
nth term = dn + (a - d) Where d is the difference between the terms, a is the first term and n is the term number.
Step-by-step explanation:
9*17 + (-6- 9)= 138
First find the common difference.
This can be found by subtracting the second term minus the
first term which in this case us 3 - (-6) or 3 + (+6) which is 9.
So we add 9 to reach the next term in this sequence.
Since this sequence isn't too long, continuing adding 9
until you reach the 17th term in this arithmetic sequence.
-6 ⇒ 1st term
3 ⇒ 2nd term
12 ⇒ 3rd term
21 ⇒ 4th term

If a wheel rotates by 1888 degrees, how many complete revolutions has it made?
The number of revolutions made by the wheel is 5.24 ≅ 5.
Finding number of revolutions:
One complete revolution is equal to 360 degrees, so to find the number of complete revolutions the wheel has made, we can divide the total number of degrees rotated by 360.
Here we have
A wheel rotated by 1888°
As we know One complete revolution is equal to 360 degrees
Hence, the angle can be rotated by the wheel in 1 rotate = 360°
Let the wheel make 'x' revolution to make 1888°
=> 360(x) = 1888
=> x = 1888/360
=> x = 5.24
Therefore,
The number of revolutions made by the wheel is 5.24 ≅ 5.

Answer:
=11/14
Step-by-step explanation:
Step-by-step explanation:
Number of blue marbles n(blue)=4
Number of red marbles n(red)=3
number of yellow marbles n(yellow)= 2
number of green marbles n(green)=5
total number of marbles n(S)=4+3+2+5=14
P(red)=n(red)/n(S)
P(red)=3/14
We have to determine the probability that the card picked is not red which means the card can be blue or yellow or green.
P(not red)=1-P(red)
=1-3/14
=11/14
Answer:
11/14
Step-by-step explanation:
These are all the marbles that are there:
4 blue
3 red
2 yellow
5 green
If you want to figure out the probability of a marble not being red, you can either find the probability that the marble is blue, yellow, or green or you could subtract the probability that the marble is red from 1 (same thing either way)
There are 14 marbles and 11 of them are not red, so the the probability that a marble drawn will not be red is 11/14.

What is equation?A mathematical equation links two statements and utilises the equals sign (=) to indicate equality. In algebra, an equation is a mathematical assertion that proves the equality of two mathematical expressions. For instance, in the equation 3x + 5 = 14, the equal sign separates the numbers by a gap. A mathematical formula may be used to determine how the two sentences on either side of a letter relate to one another. The logo and the particular piece of software are usually identical. like, for instance, 2x - 4 = 2.
The equation may be changed to read:
x = log base 3 of 81.
81 being equivalent to 3 to the power of 4, we get the following:
x Equals log base 3 of 34.

We know that the circumference is 8π inches. Thus, we can substitute 8π for C:
\(8\pi =2\pi r\)
To solve for r, the radius, we can divide both sides by 2π. Hence:

Therefore, let's find the value of x using the exterior angle theorem.
Hence,
