Convert the equation:
[tex]6x ^{2} - 3y ^{2} + 12x - 18y - 3 = 0[/tex]
to the standard form of a hyperbola.
Answer:
(x+1)²/6 - (y+3)²/12 = 1
Step-by-step explanation:
The standard form of writing the equation of an hyperbola is expressed as;
(x-h)²/a² - (y-b)²/b² = 1 where (h,k) is the centre of the hyperbola.
Given the equation:
6x²-3y²+12x-18y-3 = 0
We are to convert it to the standard form of writing the equation of a hyperbola.
Collecting the like terms will give;
(6x²+12x)-(3y²+18y)-3 = 0
Divide through by 3
(2x²+4x)-(y²+6y)-1 = 0
Completing the square of the equation in parenthesis and adding the constants to the other side of the equation:
(2x²+4x)-(y²+6y+(6/2)²)-1 = 0+(6/2)²
(2x²+4x)-(y²+6y+9)-1 = 9
2x²+4x -{(y+3)²} = 9+1
2x²+4x - (y+3)² = 10
Divide through by 2
x²+2x -(y+3)²/2 = 5
(x²+2x+(2/2)²)-(y+3)²/2 = 5+(2/2)²
(x²+2x+1) - (y+3)²/2 = 5+1
(x+1)²-(y+3)²/2 = 6
Divide through by 6
(x+1)²/6 - (y+3)²/12 = 1
The resulting equation is the required standard form of a hyperbola with centre at (-1, -3)

if the farm needs to pack 12,70,224 litchis in boxes that hold 144 litchis ,how many boxes would be required .
For this, we will divide 1,270,224 by 144.
1,270,224 ÷ 144 = 8,821.
For this result, we can conclude that the number of boxes required to pack 1,270,224 litchis is 8,821 boxes.

Solve for R: 16 + 8(R-6) = 5R + 50.
Answer:
82/3
Step-by-step explanation:
Hi! I'm back!
16+8r-48=5r+50
8r-32=5r+50
3r=82
r=82/3
Answer:
R = 82/3
Step-by-step explanation:
16 + 8(R - 6) = 5R + 50.
16 + 8 × R - 8 × 6 = 5R + 50
16 + 8R - 48 = 5R + 50
8R - 5R = 50 + 48 - 16
3R = 82
R = 82/3
R = 82/3
Thus, the value of R is 82/3
ASAP! equation of the line in slope-intercept form
Line through (2,6) and perpendicular to y+4=3x
Answer:
y = -1/3x + 6[tex]\frac{2}{3}[/tex]
Step-by-step explanation:
First, change the original equation to slope intercept form:
y + 4 = 3x
y = 3x - 4
Now, find the slope of the perpendicular line. It will be the opposite reciprocal:
The opposite reciprocal of 3 is -1/3.
Next, plug this into the slope intercept equation along with the given point, so we can solve for b:
y = mx + b
6 = -1/3(2) + b
6 = -2/3 + b
6.67 = b
So, the equation will be y = -1/3x + 6[tex]\frac{2}{3}[/tex]

What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

1-1 Relations and Functions Marcus drives 32 miles to work each day. He records the number of minutes it takes him to drive and writes his average speed as the input and the number of minutes as the output. He recorded his information in a table, like the one shown below. Speed (mph) Time (minutes) 60 32 45 43 55 35 50 38 62 31 If Marcus drives no faster than 65 miles per hour, what is the domain that includes all possible average speeds using interval notation? O A. [0, 65] B. [65,-) O C. (0, 65) D. (65,-)
Answer:
A. [0, 65]
Step-by-step explanation:
Given that
Distance that Marcus drives every day = 32 miles.
The table having average speed as input and time taken as output is shown below in the table format:
[tex]\begin{center}\begin{tabular}{ c c}Speed(mph) & Time(minutes) \\ 60 & 32 \\ 45 & 43 \\ 55 & 35 \\ 50 & 38 \\ 62 & 31 \\\end{tabular}\end{center}[/tex]
To find:
The domain that includes all possible average speeds using interval notation = ?
Solution:
First of all, let us understand what is a domain of a function.
Domain of a function is set of valid input values that can be provided to the function so that it has a valid output.
If a function is written as:
[tex]y=f(x)[/tex] then values of [tex]x[/tex] are the input given to the function.
In the given question statement, we are given that maximum Average speed attained by Marcus is 65 miles per hour.
That means domain has a maximum value of 65.
Let us learn something about interval notation.
( or ) means the value is not inclusive.
[ or ] means the value is inclusive.
Here 65 will be inclusive.
On the left side of comma, lower value is written and on the right side of comma, larger value is written.
So, domain for the current situation will be:
[0, 65]
0 is taken as the minimum value of domain here, because average speed value can not be negative.
This interval will contain all the possible values of input (average speed) as shown in the above table of values.
X has a normal distribution with the given mean and standard deviation. Find the indicated probability. (Round your answer to four decimal places.) μ = 51, σ = 10, find P(36 ≤ X ≤ 56)
Answer:
0.6247
Step-by-step explanation:
The formula for calculating a Z-score is Z = (X - μ)/σ,
where x is the raw score
μ is the population mean
σ is the population standard deviation.
From the question,
μ = 51, σ = 10. We are to find P(36 ≤ X ≤ 56)
Step 1
Find the Probability of X ≤ 36
μ = 51, σ = 10
Z = (X - μ)/σ
Z = 36 - 51/ 10
Z = -15/10
Z = -1.5
We find the Probability of Z = -1.5 from Z-Table
P(X <36) = P(X = 36) = P(Z = -1.5)
= 0.066807
Step 2
Find the Probability of X ≤ 56
μ = 51, σ = 10
Z = (X - μ)/σ
Z = 56 - 51/ 10
Z = 5/10
Z = 0.5
We find the Probability of Z = 0.5 from Z-Table:
P(X < 56) = P(X = 56) = P(Z = 0.5)= 0.69146
Step 3
Find P(36 ≤ X ≤ 56)
P(36 ≤ X ≤ 56) = P(X ≤ 56) - P(X ≤ 36)
= P( Z = 0.5) - P(Z = -1.5)
= 0.69146 - 0.066807
= 0.624653
Approximately to 4 decimal places , P(36 ≤ X ≤ 56) = 0.6247

Answer:
25 cubes
Step-by-step explanation:
Conditions are:
Each layer must be a perfect squareThe layers must be smaller starting from the bottom layerThere are 54 cubes and all of them must be stackedThen the the option is:
