What quadrant would be ordered pair (-4,-6) fall in?
Can someone solve this???
Answer:
1. a)x² + y² = 29 ------------------(1)
y² - x² = 23 ----------------(2)
y² = 23 + x²
Using the value of y² in the first equation:
x² + y² = 29
x² + (23 + x²) = 29
2x² = 6
x² = 3
x = √3
Using the value of x in equation (2)
y² - x² = 23
y² - 3 = 23
y² = 26
y = √26 and x = √3
b) ( 1 - 12x) / 3 < 0 = 1-12x < 0 = x > 1 / 12
(1-x) / 2 ≤ (3-x) 3 = 3 - 3x ≤ 6 - 2x = -3 ≤ x
In these 2 equations, the value of x will be the values of x common to both the inequalities
Since the second equation starts at a much lower value than the first equation, and they are both going up, all the values for the first equation will also stand for the second equation
Hence, the value of x for the given system of equations is
x > 1/12
2.
3x² - 7x + 2 ≥ 0
3x² -6x -1x + 2 ≥ 0 (splitting the middle term)
3x(x - 2) -(x - 2) ≥ 0
(3x - 1)(x-2) ≥ 0
(3x-1) ≥ 0 or (x-2) ≥ 0
x ≥ 1/3 or x ≥ 2
Written above are the 2 solutions for the given equation

We are given that Sin α = (2√3) / 3 or 2/√3
According to the pythagorean law:
sin²α + cos²α = 1
4 / 3 + cos²α = 1
cos²α = (3-4)/3
cos²α = -1/3
cos α = √(-1/3) or i / √3 since √-1 is also known as i
Cosec α = 1/ Sin α
Cosec α = 1 / (2/√3)
Cosec α = √3 / 2
Sec α = 1 / cos α
Sec α = 1 / √(-1/3)
Sec α = (√3) / (√-1)
Since (√-1) is also known as i , we can write this as:
Sec α = (√3) / i
Tan α = Sin α / Cos α
Tan α = (2√3 / 3) / (i / √3)
Tan α = (2√3 * √3) / 3 * i)
Tan α = 2 / i
Cot α = 1/Tan α
Cot α = 1 / (2 / i)
Cot α = i / 2

6 - 4x = 6x - 8x + 2
6 - 4x = ___ + 2
6 = ___ + 2
___ = ___
___ = x
Answer:
6 − 4 x = 6 x − 8 x − 2 Since x
is on the right side of the equation, switch the sides so it is on the left side of the equation.
6 x − 8 x − 2 = 6− 4 x Subtract 8 x from 6 x . − 2 x − 2 = 6 − 4 x
Move all terms containing x
to the left side of the equation.
Tap for fewer steps...
Add 4 x
to both sides of the equation.
− 2 x − 2 + 4 x = 6 Add − 2 x and 4 x . 2 x − 2 = 6
Move all terms not containing
x to the right side of the equation.
Tap for fewer steps...
Add 2
to both sides of the equation.
2 x = 6 + 2 Add 6 and 2 . 2 x = 8
Divide each term by

The sides of the triangle do not satisfy the Pythagorean Theorem.
Step-by-step explanation:
If we are given the three sides to a triangle, and we are asked to find out if it is a right triangle, we will have to see if the sides of the triangle satisfies the Pythagorean Theorem. The Pythagorean Theorem is:
a² + b² = c²
where c is the hypotenuse and a and b are the other two sides.
So we can see from the image that 28 would be the length of the "hypotenuse" and 19 and 20 would be the lengths of the other two sides. Lets see if these values satisfy the Pythagorean Theorem:
19² + 20² = 28²
361 + 400 = 784
761 ≠ 784
So no, the triangle is not a right triangle because the sides does not satisfy the Pythagorean Theorem.
I hope you find my answer and explanation to be helpful. Happy studying.
A penguin walks 10 feet in 6 seconds. At this speed:
How far does the penguin walk in 45 seconds?
How long does it take the penguin to walk 45 feet?
Explain or show your reasoning.
75 feet the penguin walk in 45 seconds and in 27 seconds the penguin walk 45 feet.
What is Ratio?A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.
Given,
penguin walks 10 feet in 6 seconds
At the same rate we need to find the distance walked by penguin in 45 seconds
Let x be the distance travelled by penguin in 45 seconds
10/6=x/45
Apply cross multiplication
45(10)=6x
450=6x
Divide both sides by 6
x=75
So 75 feet the penguin walk in 45 seconds.
Now let us find how long it takes for penguin to walk 45 feet.
Let x be the time
10/6=45/x
Apply cross multiplication
10x=270
Divide both sides by 10
x=27
In 27 seconds the penguin walk 45 feet.
Hence, 75 feet the penguin walk in 45 seconds and in 27 seconds the penguin walk 45 feet.

If one order of fries and five burgers cost twice as much as three orders of fries and two burgers, how many times as much does a burger cost compared to one order of fries? to start the problem is 1f+5b=2 (3f+2b)
Answer:
A burger cost five times as much as a fries.
Step-by-step explanation:
Let F represent fries
Let b represent burgers
From the question:
An order of fries and five burger can be written as:
f + 5b
Three orders of fries and two burgers can be written as:
3f + 2b
But an order of fries and five burgers cost twice as much as three orders of fries and two burgers. This can be written as:
f + 5b = 2(3f + 2b)
Now, we shall make b the subject of the above equation. This is illustrated below:
f + 5b = 2(3f + 2b)
Clear bracket
f + 5b = 6f + 4b
Collect like terms
5b – 4b = 6f – f
b = 5f
Thus, a burger cost five times as much as a fries.
if ta=16 & mh= 18 what is the lenth of mr?
Answer:
the length of MR = 9
Step-by-step explanation:
Looking at the figure, we can tell that segment TR is congruent to segment RA, meaning TR has equal length to RA and the same goes to MR and RH. Since the problem gives us the total length of line TA and line MH, we can say that the length of MR is half of the total length of MH. Therefore, length of MR is 9.

To buy a car, you borrow $25,000 with a term of three years at an APR of 6.5%. What is your monthly
payment? Show all work
Answer:
$766.23
Step-by-step explanation:
The amortization formula is appropriate for this. (Better, use a financial calculator or spreadsheet.)
A = P(r/12)/(1 -(1 +r/12)^-(12t))
where P is the amount borrowed (25,000), r is the annual rate (0.065), and t is the number of years (3).
Putting the given numbers into the formula, we have ...
A = $25,000(0.065/12)/(1 -(1 +0.065/12)^(-36))
A = $25,000(.00541667)/(1 -1.00541667^-36)
A = $25,000(0.00541667)/(0.1767322)
A = $766.23
The monthly payment is $766.23.

The authors of a certain paper describe a study to evaluate the effect of mobile phone use by taxi drivers in Greece. Fifty taxi drivers drove in a driving simulator where they were following a lead car. The drivers were asked to carry on a conversation on a mobile phone while driving, and the following distance (the distance between the taxi and the lead car) was recorded. The sample mean following distance was 3.80 meters and the sample standard deviation was 1.19 meters.
Construct a 95% confidence interval (in meters) for μ, the population mean following distance while talking on a mobile phone for the population of taxi drivers. (Round your answers to three decimal places.)
Answer:
CI = (3.462, 4.138)
Step-by-step explanation:
We are given;
Sample mean; x¯ = 3.8
Sample standard deviation; s = 1.19
Sample size; n = 50
DF = n - 1 = 50 - 1 = 49
Confidence level; CL = 95%
Significance level = (1 - 0.95)/2 = 0.025
Now,from the table attached using DF = 49, significance level = 0.025, one tail and by interpolation, we have; t = 2.01
Now, formula for confidence interval is;
CI = x¯ ± t(s/√n)
CI = 3.8 ± 2.01(1.19/√50)
CI = 3.8 ± 0.338
CI = (3.8 - 0.338, 3.8 + 0.338)
CI = (3.462, 4.138)
