What type of exponential function is f(x)=0.6(2.4)^x?
What is the function's percent rate of change?
Select from the drop-down menus to correctly complete each statement.
The function is an exponential CHOOSE function.
The percent rate of change of the function is CHOOSE%.
Answer:
growth
140%
Step-by-step explanation:
The function f(x) is an exponential growth function as f(x) increases when x increases.
The percent rate of change of the function f(x) is 201.6%.
What is a function?A function is a relationship between inputs where each input is related to exactly one output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
f(x) = 0.6 [tex](2.4)^x[/tex]
For x = 1,
f(1) = 0.6 x 2.4 = 1.44
For x = 2,
f(2) = 0.6 x 2.4² = 0.6 x 5.76 = 3.456
For x = 3,
f(3) = 0.6 x 2.4³ = 0.6 x 18.824 = 8.2944
We see that,
As the value of x increases, the value of f(x) increases.
f(x) is an exponential growth function.
Now,
The percentage rate of change of function f(x).
= (f(2) - f(1)) / (2 - 1) x 100
= (3.456 - 1.44) x 100
= 2.016 x 100
= 201.6 %
Thus,
f(x) is an exponential growth function.
f(x) percent rate of change is 201.6%

What is a function?A function has an input and an output.
A function can be one-to-one or onto one.
It simply indicated the relationships between the input and the output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
The zero of a function is a value of the independent variable (usually denoted as x) for which the value of the function (denoted as f(x)) is equal to zero.
In other words, the zero of a function is the value of x that makes the function equal to zero.
It is also known as a root or a solution of the function.
Geometrically, the zero of a function is the x-intercept of its graph, which is the point where the function crosses the x-axis.
Now,
From the function graph,
The graph has f(x) = y = 0 at the x = -5.
Thus,
The zero of the function represented by this graph is at x = -5.

Which athletes, if any, would qualify for the finals if the length of a jump that qualifies for the finals were at least 20 feet?
Answer:
Amir and ryan would qualifiey
Step-by-step explanation:
The Johnson family decides to take a trip to the theater over the holiday break. Theater tickets for adults cost $22. Children's tickets cost $15. 11 people went to see the play and the total cost was $228.
Let x= # of adults
Let y = # of children
Part A
Which equation represents the total number of people who went to see the play?
a.11x + 22 = 228
b.y = 15x + 11
c.22x + 15y = 228
d.x + y = 11
Part B
Which equation represents the total cost of the trip to the theater?
a.11x + 22 = 228
b.x + y = 11
c.y = 15x + 11
d.22x + 15y = 228
Answer:
a. 11 people went to see the play. the equation for the number of people who went is x + y = 11 because we don't know how many adults or children.
b. 22 dollars per adult, 15 dollars per child. since we don't know how many kids or how many adults, they're represented by x and y (as shown in part a)
the equation to represent the total cost is 22x + 15y =228 because the total cost to go was 228 and that's the only equation that has both variables and the total cost

In a batch of 440 water purifiers, 8 were found to be defective. What is the probability that a water purifier chosen at random will be defective? Write the probability as a percent. Round to the nearest tenth of a percent if necessary!
please help
Answer:
1.8% or 1.818181%
Step-by-step explanation:
If in a batch of 440 water purifiers, we find 8 to be defective.
Then the probability of the next purifier being defective is 8/440
In percentage = 8/440 * 100
=> 8/44 * 10
=> 8/22 * 5
=> 40/22
=> 20 / 11
20/11 is roughly 1.8181818
Rounding it to the nearest tenth, we get 1.8%

For an experiment, a scientist needs 1/2 cup baking soda for 4/5 liter of water. Using this ratio, how much baking soda is needed for one liter of water?
Answer choices-
4/10 cup
5/8 cup
8/5 cups
10/4 cups
Answer:
5/8 cup of baking powder.
Step-by-step explanation:
Hence, using the ration given in the above question:
4/5 liter of water = 1/2 cup of baking soda
1 liter of water = x cup of baking powder
Cross Multiply
4/5 liter of water × x cup of baking powder = 1 liter of water × 1/2cup of baking powder
x cup of baking powder = 1 liter of water × 1/2cup of baking powder/4/5 liter of water
x cup of baking powder = 1/2 ÷ 4/5
x cup of baking powder = 1/2 × 5/4
x cup of baking powder = 5/8 cup of baking powder.
Therefore,
5/8 cup of baking soda is needed for one liter of water.

The value of x will be:

or
[tex]x = 31.1[/tex]
Step-by-step explanation:
Given
a = 22b = 22To determine
hypotenuse x = ?
For a right-angled triangle with sides, a and b the hypotenuse c is defined as
[tex]c=\sqrt{a^2+b^2}[/tex]
substituting a = 22, b = 22 and c = x
[tex]x=\sqrt{22^2+22^2}[/tex]
[tex]x=\sqrt{22^2\cdot \:2}[/tex]
Apply radical rule: [tex]\sqrt[n]{ab}=\sqrt[n]{a}\sqrt[n]{b},\:\quad \mathrm{\:assuming\:}a\ge 0,\:b\ge 0[/tex]
[tex]x=\sqrt{2}\sqrt{22^2}[/tex]
[tex]x=22\sqrt{2}[/tex]
or
[tex]x = 31.1[/tex]
Therefore, the value of x will be:
[tex]x=22\sqrt{2}[/tex]
or
[tex]x = 31.1[/tex]

Given:
The graph of linear function.
To find:
The rate of change the given linear function.
Solution:
From the given graph it is clear that the line passes through the points (0,1) and (1,-1). So, rate of change is
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\dfrac{-1-1}{1-0}[/tex]

Help ASAP.. Find the measure of each missing angle .. M<1? M<2? M<3? M<4? M<5?
Answer:
m<1=62°
m<2=23°
m<3=157°
m<4=23°
m<5=62°
Step-by-step explanation:
m<1= 180-118=62
m<2=180-95-62=23
m<3=180-23=157
m<4=m<2=23
m<5=m<1=62
Measures of the missing angles
m∠1 = 62° , m∠2 = 23°, m∠3 = 157° , m∠4 = 23° , m∠5= 62°
What is an angle?An angle is the figure formed by two rays called sides of the angle sharing a common endpoint called the vertex of the angle.
Given,
In the figure
sum of angles on a straight line is 180° .
m∠1 + 118° = 180°
m∠1 = 180° - 118°
m∠1 = 62°
In a triangle, measurement of all interior angles is 180°
m∠1 + m∠2 + 95° = 180°
62° + m∠2 + 95° = 180°
m∠2 + 157° = 180°
m∠2 = 180° - 157°
m∠2 = 23°
Sum of angles on a straight line is 180°
m∠2 + m∠3 = 180°
23° + m∠3 = 180
m∠3 = 180° - 23°
m∠3 = 157°
Since ∠2 and ∠4 are supplementary angles
m∠4 = m∠2
m∠4 = 23°
Sum of all interior angles of a quadrilateral is 360°
m∠3 + m∠4 + m∠5 + 118° = 360°
157 + 23 + m∠5 +118 = 360
m∠5 + 298 = 360
m∠5 = 360 - 298
m∠5 = 62°
Hence, m∠1 = 62°, m∠2 = 23°, m∠3 = 157°, m∠4 = 23°, m∠5= 62° are the measures of the missing angles.

Marvel use 864 beads to make necklaces for the art Club she made 24 necklaces with the beads if each necklace has the same amount of beads how many babies did Markle used to make each necklace
Answer:
I think the answer is 20736 beads?
Step-by-step explanation:
If the last sentence is supposed to say beads instead of babies, the answer is 20736 beads. This is because if u multiply the amount of beads used in one bracelet by the amount of bracelets, you should get the total amount of beads. So the two quantities are 864 and 24. If you multiply the two, then you get the total amount of 20736 beads.

Where
H is Hypotenuse
b is base
h is perpendicular height
If we put b = 3. h = 4, then

Answer:
The value of f(x) - g(x) is:
f(x) - g(x) = 2x² + 6x - 4
Step-by-step explanation:
Given
f(x) = 3x² + x - 3
g(x) = x² - 5x + 1
To determine
f(x) - g(x)
Using the formula
f(x) - g(x) = 3x² + x - 3 - ( x² - 5x + 1)
= 3x² + x - 3 - x² + 5x - 1
= 2x² + 6x - 4
Therefore, the value of f(x) - g(x) is:
f(x) - g(x) = 2x² + 6x - 4
