Give the required elements of the hyperbolas below.
1. x^2/9 - y^2/16 =1
a. 3
b. 4
c. 9
d. 16
2. 4x^2 - y^2 = 16
a. 1
b. 2
c. 4
d. 16
3. 2y^2 - 3x^2 =6
a. √ ̅2
b. √ ̅3
c. 2
d. 3
Final answer:
The hyperbolas' equations are analyzed to find the values of a² and b². For the first equation, a² is 9 and b² is 16; for the second, a² is 4 and b² is 16; and for the third, a² is 3 and b² is 2.
Explanation:
To identify the required elements for each of the hyperbolas, we need to look at the equations of the hyperbolas and determine the values of a and b, which are the square roots of the denominators of the x-squared and y-squared terms when they are in the standard form for a hyperbola, x²/a² - y²/b² = 1 for horizontal hyperbolas, and y²/a² - x²/b² = 1 for vertical hyperbolas.
1. For the hyperbola x²/9 - y²/16 = 1, the required elements are a² and b². Hence, a² = 9 and b² = 16, leading to the answers being c and d respectively.
2. The hyperbola 4x² - y² = 16 can be rearranged to x²/4 - y²/16 = 1. Here, a² = 4 and b² = 16, making the answers c and d respectively.
3. For hyperbola 2y² - 3x² = 6, it rearranges to y²/3 - x²/2 = 1. In this case, a² = 3 and b² = 2, so the answers are d and a respectively, since we are looking for a and b, not a² and b².

which equation below will produce a decay curve
y=2(4)^x
y=3^x-4
y=6(1/3)^x
y=1/2(3)^x
answer : y=6(1/3)^x, option C
Decay curve means when x value increases the y value will decrease.
We plug in 3 values for x and check the y value
Lets start with first option
[tex] y=2(4)^x [/tex]
x=0 , y= 2
x=1, y= 8
x=2, y=32
when x value increases the y value also increases. so option A is not a decay curve
[tex] y=3^x -4 [/tex]
x=0 , y= -4
x=1 , y= -1
x=2 , y = 5
when x value increases the y value also increases. so option B is not a decay curve.
[tex] y= 6(\frac{1}{3})^x [/tex]
x=0, y = 6
x=1, y = 2
x=2 , y= 0.67
when x value increases the y value decreases. so option C is a decay curve
The equation that will produce a decay curve is y = 6(1/3)^x.
Explanation:The equation that will produce a decay curve is y = 6(1/3)x.
A decay curve is characterized by exponential decay, where the base of the exponent is less than 1. In this equation, the base is 1/3, which is less than 1. As x increases, the value of (1/3)x decreases, resulting in a decay curve.
For example, if we substitute x = 0 into the equation, we have y = 6(1/3)0 = 6(1) = 6. As x increases, the value of y decreases exponentially.

Mel slides down waterslide A, and Victor slides down waterslide B. After 2 seconds, Mel was 50 feet in the air, and after 5 seconds, she was 35 feet in the air. After 1 second, Victor was 60 feet in the air, and after 4 seconds, he was 50 feet in the air. Who was descending at a faster rate?
Mel: (2, 50) and (5, 35)
Victor: (1, 60) and (4, 50)
Mel’s rate of change is____.That means that her height in the air decreases _____ feet every second.
Victor’s rate of change is _____ . That means that his height in the air decreases _____ feet every second.
The height of Mel in the air is decreasing at a faster rate than victor's height in the air.
Mel's rate of change is -5 feet per second. That means that her height in the air decreases 5 feet every second. Victor's rate of change is -3.33 feet per second. That means that his height in air decreases 3.33 feet every second.Given information:
Mel slides down water-slide A and Victor slides down water-slide B.
After 1 second, height achieved by [tex]\rm{Mel}= 50\; \text{Ft}[/tex]
After 5 seconds, the height remained is 35 feet.
In another case,
The height achieved by Victor after 1 second is 60 feet.The height remained after 4 second is 50 feet.Now, the expression is used for evaluating the slope of the equation are formulated below:
[tex]\bold{m=\dfrac{y_2-y_1}{x_2-x_1}}[/tex]
Where, [tex]m[/tex] is the slope and [tex]x[/tex] and [tex]y[/tex] are respective coordinates.
Hence, for Mel's case, apply the formula of slope and solve it further:
[tex]\begin{aligned}m_1&=\dfrac{35-50}{5-2} \\m_1&=-5 \end{aligned}[/tex]
So, the rate of change of Mel's height is 5 feet per second.
And for victor's case, slope will be:
[tex]m_2=\dfrac{50-60}{4-1} \\\\m_2=-3.33[/tex]
The rate of change of victor's height is 3.33 feet per second.
Mel's rate of change is -5 feet per second. That means that her height in the air decreases 5 feet every second.Victor's rate of change is -3.33 feet per second. That means that his height in air decreases 3.33 feet every second.For more information visit:

Terrance run 6 miles every half hour Jesse runs 2 miles every 15 minutes and Sandra runs at a rate of 8 miles in 45 minutes. How does Sandra unit rate compare to terrance and Jesse
To compare Sandra's unit rate with Terrance's and Jesse's, we must calculate their speeds in mph. Terrance runs at 12 mph, Jesse at 8 mph, and Sandra at 10.67 mph. Therefore, Sandra is faster than Jesse but slower than Terrance.
To compare Sandra's unit rate to Terrance's and Jesse's, we need to determine the speed at which each person runs in miles per hour (mph). The given information is:
Terrance runs 6 miles every half hour.
Jesse runs 2 miles every 15 minutes.
Sandra runs 8 miles in 45 minutes.
First, we calculate each person's running speed:
Terrance: 6 miles in 0.5 hours (30 minutes), so we multiply by 2 to find his speed per hour: 6 miles ÷ 0.5 hours = 12 mph.
Jesse: 2 miles in 0.25 hours (15 minutes), so we multiply by 4 to find his speed per hour: 2 miles ÷ 0.25 hours = 8 mph.
Sandra: 8 miles in 0.75 hours (45 minutes), so we divide her distance by the time in hours: 8 miles ÷ 0.75 hours = 10.67 mph.
Therefore, compared to Terrance and Jesse, Sandra's running speed is:
Faster than Jesse's (10.67 mph > 8 mph)
Slower than Terrance's (10.67 mph < 12 mph)

Which ordered pair is the best estimate for the solution of the system of equations? y = −1/5x + 1 y = x + 4
Final answer:
The solution to the system of equations y = -1/5x + 1 and y = x + 4 is found by setting the equations equal to each other, solving for x, and then substituting back to find y. The solution is the ordered pair (-5, -1).
Explanation:
The student is asking to find the ordered pair that represents the best estimate for the solution to a system of linear equations. The given system of equations is: y = −1/5x + 1 and y = x + 4. To find the solution, we need to determine where the two lines intersect, which will give us the coordinates (x, y) of the solution.
To find the intersection, we can set the two equations equal to each other since they both equal y: −1/5x + 1 = x + 4. Then, we would solve for x:
Add 1/5x to both sides to get 1 = 6/5x + 4
Subtract 4 from both sides to get −3 = 6/5x
Multiply both sides by 5/6 to get x = −3 × (5/6)
Which simplifies to x = −5
Now we substitute x back into either of the original equations to find y. For instance, using the second equation y = x + 4, we find that:
y = (−5) + 4 = −1
Therefore, the ordered pair that is the solution to the system of equations is (-5, -1).
determine which fraction goes in the middle to make the comparison true. 5/8< ? < 8/10. so the answer to pick from are 1/2,1/3,7/10,1/4
The fraction that goes in the middle to make the comparison true is 7/10.
5/8 < 7/10 < 8/10
Option C is the correct answer.
What is a fraction?A fraction is written in the form of a numerator and a denominator where the denominator is greater that the numerator.
Example: 1/2, 1/3 is a fraction.
We have,
5/8 < x < 8/10
The value for x is greater than 5/8 but less than 8/10.
1/2 is less than 5/8.
1/3 is less than 5/8.
7/10 is greater than 5/8 and less than 8/10.
1/4 is less than 5/8.
