how do u find the constant RATIO of the exponential curve
Answer:
We call base 2 the constant ratio. In fact, for any exponential function with the form f(x)=abx f ( x ) = a b x , b is the constant ratio of the function. This means that as the input increases by 1, the output value will be the product of the base and the previous output, regardless of the value of a.
Step-by-step explanation:
Notice from the table that:
the output values are positive for all values of x
as x increases, the output values increase without bound
as x decreases, the output values grow smaller, approaching zero
The graph below shows the exponential growth function
f(x)=2x
Find the equation of the hyperbola if y=2x−5 and y=−2x+3 are the asymptotes, and it is known that one of the vertices is on the y-axis.
Answer:
(x-2)^2/4 - (y+1)^2/16 = 1
Step-by-step explanation:
The first thing you want to do is find the center of the hyperbola. Since you have the two equations of the asymptotes, their intersection must be what you want. setting 2x - 5 equal to -2x + 3, you get that x = 2, meaning that 2 is the x-coord of your center. Plugging this value of x into the equations, you get that y = -1. Now that you have your center, you have the information that one of the vertices is on the y-axis. Since the distance from the center to the vertice must be a straight line, you know for sure that this hyperbola is a horizontal one (a vertical one would not have a vertice on the y-axis given this center). Knowing this, you have the equation form (x-2)^2/a^2 - (y+1)^2/b^2 = 1. I got a little confused here, but remember that you now know the center and the equations of the asymptotes. y = 2x - 5 is equal to 2(x - 2) - 1. The form of the asymptotes of a horizontal hyperbola is b/a(x-h) + k, which means that b/a must be equal to 2. This also means that 2a = b, and 4a^2 = b^2. Now you can substitute b^2 for 4a^2, leaving you with the equation (x-2)^2/a^2 - (y+1)^2/ 4a^2 = 1. Remember that vertice on the y-axis? Since it must be at the same y-coordinate (since you know that it must be a horizontal line from the center to the vertice), you know the vertice has to be (0, -1). You can plug these values into the previous equation, which gives you (0 - 2)^2 / a^2 - 0 = 1. This leaves you with 4/a^2 = 1, which means that a must be 2. Since you already know that b is 2a, b must be equal to 4. Plugging those values into the equation, you get your final answer, (x-2)^2/4 - (y+1)^2/16 = 1.

A robot can complete 8 tasks in ⅚ hour. Each task takes the same amount of time. How long does it take the robot to complete one task? It takes the robot ___1___ hour(s) to complete one task. How many tasks can the robot complete in one hour? The robot can complete ______ task(s) in one hour.
Answer:
1 task = 6.25 minutes
The robot can complete 9.6 task in 1 hour
Step-by-step explanation:
Number of task = 8
Time taken = 5/6 of 1 hour
5/8 of 1 hour = 5/6 × 60 minutes
= 300/6
= 50 minutes
8 task takes 50 minutes
1 task = 50 minutes / 8 task
= 6.25 minutes
1 task = 6.25 minutes
x task = 60 minutes
1 : 6.25 = x : 60
1/6.25 = x / 60
1*60 = 6.25*x
60 = 6.25x
x = 60/6.25
= 9.6
x= 9.6
The robot can complete 9.6 task in 1 hour

Answer:
The length of the third side is √73
Step-by-step explanation:
To find the third side, we use the Pythagorean Theorem: a² + b² = c²
a² and b² are the two smaller sides
c² is the longest side
The two shortest sides are 4√2 and ?
The longest side is 9
a² = 4√2²
b² = ?
c² = 9²
Now we put together the equation:
4(√2)² + b² = 9²
The square of √2 is 2
4 × 2 + b² = 9²
Multiply 4 and 2 to get 8
8 + b² = 9²
Calculate 9 to the power of 2 and get 81
8 + b² = 81
Subtract 8 from both sides
8 + b² - 8 = 81 - 8
Subtract 8 from 81 to get 73
b² = 73
Take the square root of both sides of the equation
√b² = √73
Simplify
b = √73
Length of third side: √73

The opposite angles of cyclic quadrilateral are(3X+10) and (2X+20). Find the angles.
Answer:
40°
Step-by-step explanation:
Opposite angles in a cyclic quadrilateral are equal
3x + 10 = 2x + 20
Take away 2x from both sides
x + 10 = 20
Take away 10 from both sides
x = 10
Now that we know the value of x, substitute it back into the equations
3x + 10 = 3 x 10 + 10 = 30 + 10 = 40
2x + 20 = 2 x 10 + 20 = 20 + 20 = 40
Both angles are equal to 40°
Step-by-step explanation:
Need to FinD :We have to find the angles.[tex] \red{\frak{Given}} \begin{cases} & \sf {We\ are\ given\ a\ cyclic\ quadrilateral.} \\ & \sf {The\ measures\ of\ the\ opposite\ angles\ of\ the\ quadrilateral\ are\ {\pmb{\sf{(3x\ +\ 10)^{\circ}}}}\ and\ {\pmb{\sf{(2x\ +\ 20)^{\circ}}}}.} \end{cases}[/tex]
We know that,
The opposite angles of the cyclic quadrilateral are (3x + 10)° and (2x + 20)°. And we have to find the angles.In a cyclic quadrilateral, all the four vertices of the quadrilateral lie on the circumference of the circle. The opposite angles in a cyclic quadrilateral add up to 180°. So simply, we just simplify the measures and find the value of x. And at last, we'll find the angles of the quadrilateral.
[tex]\rule{200}{3}[/tex]
[tex] \sf \dashrightarrow {(3x\ +\ 10)\ +\ (2x\ +\ 20)\ =\ 180} \\ \\ \\ \sf \dashrightarrow {3x\ +\ 10\ +\ 2x\ +\ 20\ =\ 180} \\ \\ \\ \sf \dashrightarrow {5x\ +\ 30\ =\ 180} \\ \\ \\ \sf \dashrightarrow {5x\ =\ 180\ -\ 30} \\ \\ \\ \sf \dashrightarrow {5x\ =\ 150} \\ \\ \\ \sf \dashrightarrow {x\ =\ \dfrac{\cancel{150}}{\cancel{5}}} \\ \\ \\ \dashrightarrow {\underbrace{\boxed{\pink{\frak{x\ =\ 30.}}}}_{\sf \blue{\tiny{Value\ of\ x}}}} [/tex]
∴ Hence, the required value of x is 30. Now, let us find out the angles.
[tex]\rule{200}{3}[/tex]
First AnglE :
3x + 103(30) + 1090 + 10100∴ Hence, the measure of the first angle of the quadrilateral is 100°.
[tex]\rule{200}{3}[/tex]
Second AnglE :
2x + 202(30) + 2060 + 2080∴ Hence, the measure of the second angle of the quadrilateral is 80°.
