Write 9x² - 36x = 4y² + 24y + 36 in standard form
this is a graph of a hyperbola, if this helps.
please include the steps on how you did it
Thank you!
Answer:
9·x² - 36·x = 4·y² + 24·y + 36 in standard form is;
(x - 2)²/2² - (y + 3)²/3² = 1
Step-by-step explanation:
The standard form of a hyperbola is given as follows;
(x - h)²/a² - (y - k)²/b² = 1 or (y - k)²/b² - (x - h)²/a² = 1
The given equation is presented as follows;
9·x² - 36·x = 4·y² + 24·y + 36
By completing the square, we get;
(3·x - 6)·(3·x - 6) - 36 = (2·y + 6)·(2·y + 6)
(3·x - 6)² - 36 = (2·y + 6)²
(3·x - 6)² - (2·y + 6)² = 36
(3·x - 6)²/36 - (2·y + 6)²/36 = 36/36 = 1
(3·x - 6)²/6² - (2·y + 6)²/6² = 1
3²·(x - 2)²/6² - 2²·(y + 3)²/6² = 1
(x - 2)²/2² - (y + 3)²/3² = 1
The equation of the hyperbola is (x - 2)²/2² - (y + 3)²/3² = 1.
The five marathon runners weigh an average weight of 92 pounds, Nicole weighs 89 pounds, Jon weighs 95 pounds, Jenny and Kim weigh 90 pounds each, How much does Jordin weigh?
Answer:
Jordin weighs 96 pounds
Step-by-step explanation:
The Mean Value of a Data Set
The mean or average of a data set is found by adding all numbers and then dividing by the number of values in the set. Written as a formula:
[tex]\displaystyle \bar x=\frac{\sum x_i}{n}[/tex]
Where xi is the value of each data and n is the total number of values.
We are given the average weight of n=5 marathon runners:
[tex]\bar x=92[/tex]
Multiplying the formula by n and expanding the sum:
[tex]n\bar x=\sum x_i=x_1+x_2+x_3+x_4+x_5[/tex]
We are given the weighs of four of the runners:
[tex]5*92=89+95+90+90+x_5[/tex]
[tex]460=364+x_5[/tex]
Solving for x5:
[tex]x_5 = 460-364=96[/tex]
Jordin weighs 96 pounds

Diane buys candy that costs $4 per pound. She will spend more than $20 on candy. What are the possible numbers of pounds she will buy?
Use
P
for the number of pounds Diane will buy.
Write your answer as an inequality solved for p.
Answer:
12 pounds
Step-by-step explanation:
We know that the candy costs $4 per pound
We also know that he will only spend up to $48
We can represent this as an equation:
4x = 48
Where as x = number of pounds
Solve the equation to find how many pounds he can buy.
4x = 48
Divide both sides by 4
x = 12
This means that Kareem can buy 12 pounds

Step-by-step explanation:
Well, first let's look at our trig identities. We can set up a cosine function using the given angle:
[tex]cos (46^{o} ) = \frac{x}{16}[/tex] (adjacent/hypotenuse)
Then, multiplying both sides by 16 gives us:

Last answer choice is 2 1/4
Answer:
-9 1/4
Step-by-step explanation:
So what I did was that I put it this for which was -((5+3)+(3/4+1/2)
which then you would get -(8+(3/4+1/2)) which gives you -(8+5/4) because you would convert the 1/2 into 2/4 making it to get 5/4. So then you add the -(8+5/4) which gives you -9 1/4.

Renting roller blades costs a flate fee of $5 plus an additional $2.50 per hour. Write a linear equation that models this.
Answer:
Linear equation : y = 2.50h + 5
Step-by-step explanation:
Given that:
Fee for renting roller blades = $5
Per hour charges = $2.50
Let,
h be the number of hours roller blades were rented
y be the total amount
Total amount = Per hour charges * Number of hours + Flat fee
y = 2.50h + 5
Hence,
Linear equation : y = 2.50h + 5

Chase thought that only 23 people Would come to the banquet but 48 people endd up coming what was his percent error
Answer:
the percent of people that end up coming as error is 12%
Chase made a miscalculation of 52.08% percent.
What is Percentage Error?
The percent error is the distinction between the estimated value and the actual value in relation to the actual value. In other words, the relative error is multiplied by 100 to calculate the percent error.
Given that, Chase anticipated that just 23 people would attend the event; however, 48 individuals showed up.
The general formula for percentage error:
Percentage Error(%e) = ((Estimated Number – Actual Number)/ Actual number) x 100.
Hence,
Percentage error done by chase = (23 - 48) * 100/48
Percentage error done by chase = -52.08%
Therefore, the Percentage error done by chase is 52.08%

0.1(0.5m+6)=2
Answer:
m = 28
Step-by-step explanation:
The given expression is :
0.1(0.5m+6)=2
Step 1.
Use distributive property:
0.1(0.5m) +0.1(6) = 2
0.05 m+ 0.6 = 2
Step 2.
Subtract 0.6 both sides
0.05 m+ 0.6 -0.6= 2 -0.6
0.05 m = 1.4
or
0.5 m = 14
Step 3.
Divide both sides by 0.5
[tex]m=\dfrac{14}{0.5}\\\\m= 28[/tex]
Gabi's third step is not correct. It should be m = 28 instead of m = 7.
LMNO is a parallelogram. If NM = x + 15 and OL = 3x + 5 find the value of x and then find NM and OL.
Answer:
x = 5 unit
NM = 20 unit
OL = 20 unit
Step-by-step explanation:
Given:
LMNO is parallelogram
NM = x + 15
OL = 3x + 5
Find:
x and NM and OL
So,
NM = OL
x + 15 = 3x + 5
2x = 10
x = 5
So,
NM = x + 15 = 5 + 15 = 20
OL = 3x + 5 =3(5)+5 = 20
