A quadratic function and an exponential function are graphed below. Which graph most likely represents the exponential function?
A. p(x), because an increasing exponential function will always exceed an increasing quadratic function until their graphs intersect
B. t(x), because an increasing quadratic function will always exceed an increasing exponential function until their graphs intersect
C. p(x), because an increasing quadratic function will eventually exceed an increasing exponential function
D. t(x), because an increasing exponential function will eventually exceed an increasing quadratic function
Answer:
A. p(x) , because an increasing exponential function will always exceed an increasing quadratic function untill their graph intersect.Step-by-step explanation:
Given two functions are one is quadratic function and other is exponential function.
From the given graph of quadratic function and exponential function we can see that the graph of exponential function intersect y -axis at (0,1) and can never be zero and the graph of quadratic function intersect axis at origin (0,0).
From the given graph we can see that graph of exponential function increasing greater than an increasing quadratic function untill their graph intersect.
From the given graph we can see that the graph of an increasing quadratic function eventually exceed after intersection the graph of an increasing exponential function.

Therefore, it is false.We can see from given graph.
C. p(x) , because an increasing quadratic function will eventually exceed an increasing exponential function . It is false , because after intersection not eventually ,the graph of an increasing quadratic function will exceed an increasing exponential function .
D. t(x) , because an increasing exponential function will eventually exceed an increasing quadratic function . It is false , we can see from given graphs of two functions.
In the circle graph, what is the measure of the central angle for corn?
Round your answer to the nearest whole number
multiply the percentage of the corn by 360 degrees
15% × 360° = 54°
Answer:
54°
Step-by-step explanation:
In the given pie chart which shows variation of vegetable.
Pie chart is a circular. Complete angle of circular is 360°.
100% of pie chart is equal to 360° of central angle.
Here, we need to find the central angle of corn.
In graph, corn is only 15%
100% of central angle = 360°
1% of central angle [tex]=\dfrac{360^\circ}{100}[/tex]
15% of central angle [tex]=\dfrac{360^\circ}{100}\times 15[/tex]
[tex]=54^\circ[/tex]
Hence, The central angle of corn is 54°

The Three Stooges (Larry, Moe, and Curly) and the four Marx Brothers (Chico, Harpo, Groucho, and Zeppo) are randomly assigned a place in line. What is the probability the first three in line will be Moe, Larry, and Curly in that order?
Answer:
[tex]\frac{1}{210}[/tex]
Step-by-step explanation:
We can use the probability that one person will be assigned to one place.
For the first place in line, what is the probability that Moe will stand there?
[tex]\frac{1}{7}[/tex] because there is 7 people and 1 of Moe.
Then, for the second place in line, what is the probability that Larry will stand there?
[tex]\frac{1}{6}[/tex] because there are 6 people now and one of Larry.
Finally, for the third place in line, what is the probability that Curly will stand there?
[tex]\frac{1}{5}[/tex] because there are 5 people now and one of Curly.
To find the probability that they'll stand in that order, we can multiply the probabilities together.
[tex]\frac{1}{7}*\frac{1}{6}*\frac{1}{5}=\frac{1}{210}[/tex]
A taxi cab charges $1.75 for the flat fee and $0.25 for each time. Write an in equality to determine how many miles Eddie can travel if he has $15 to spend.
Answer:
53 miles
Step-by-step explanation:
I'm going to assume "$0.25 for each time" is "$0.25 per mile."
$1.75 is the flat fee. It costs 25 cents for each mile. We can represent this as:
1.75 + 0.25m
The sum of this equation has to be less than or equal to $15. We can display this as:
1.75 + 0.25m ≤ 15.
To solve, we must first isolate 0.25m. To do this, we subtract 1.75 from each side.
0.25m ≤ 15 - 1.75
0.25m ≤ 13.25.
Now, we must isolate the variable 'm' to determine how many miles Eddie can travel. To do this, we divide 0.25 from each side.
m ≤ 13.25 / 0.25
m ≤ 53.
Therefore, Eddie can travel 53 miles if he has $15 to spend.
Figure ABCD is a parallelogram. What are the measures of angles B and D?
Answer:
c
Step-by-step explanation:
The measures of angle B and angle D of the given parallelogram will be 55°, i.e. option A.
What is parallelogram?Parallelogram is a 2D shape, having opposite sides parallel and equal. Also the opposite angles of parallelogram are congruent means equal.
We have,
A Parallelogram with,
Angle B = (2n + 15)° and,
Angle D = (3n - 5)°
So,
As mentioned above in the definition that the opposite angles of parallelogram are congruent means equal.
i.e.
Angle B = Angle D
i.e.
2n + 15 = 3n - 5
On solving we get,
20 = n
⇒ n = 20,
So,
Angle B = (2n + 15)° = (2 * 20 + 15)° = 55°
And,
Angle D = (3n - 5)° = (3 * 20 - 5)° = 55°
Hence, we can say that the measures of angle B and angle D of the given parallelogram will be 55°, i.e. option A.

At the beginning of a class period, half of the students in a class go to the library. Later in the period, half of the remaining students go to the computer lab. If there are eight students remaining in class, how many students were originally in the class?
Answer:
32 students
Step-by-step explanation:
We are given that at the beginning of a class period, half of the students in a class go to the library and half of the remaining to the computer lab.
Given that there are 8 students remaining, we are to find the total number of students in the class initially.
At beginning = [tex]x[/tex] students
After half of them leave = [tex]\frac{x}{2}[/tex] students
After half of the remaining leave = [tex]\frac{x}{4}[/tex] students
So, [tex]\frac{x}{4} = 8[/tex]
[tex]x=8\times 4[/tex]
x = 32
Therefore, there were 32 students in the class originally.
there were 32 students in the class originally.
because in the computer lab before there were 16. 16 times 2 equals 32.

Answer:
f(5) = 7.5
Step-by-step explanation:
The recursive formula allows a term in the sequence to be found from the previous term, thus
f(2) = - 0.5 f(1) = - 0.5 × 120 = - 60
f(3) = - 0.5f(2) = - 0.5 × - 60 = 30
f(4) = - 0.5f(3) = - 0.5 × 30 = - 15
f(5) = - 0.5f(4) = - 0.5 × - 15 = 7.5

The volume of a triangular prism is the area of the triangular base times the height of the prism.
We calculate the volume using the formula:
[tex]volume = \frac{1}{2} bh \times H[/tex]
where b=4 is the base of the triangle and h=3 is the height of the triangle.
H=11 is the height of the prism.
We substitute these values to get;

Which of the following shows the graph of y=2e^x
The answer is:
The first option shows the graph of the given function.
Why?Since the given function is an exponential function, we are looking for an exponential function graph, with a function that intercepts the y-axis at y equal to 2, or the point (0,2).
So, since we are given just one exponential graph, let's find the y-axis intercept in order to assure that the correct option is the first graph.
The function is:
[tex]y=2e^{x}[/tex]
Finding the y-axis intercept, we need to make "x" equal to 0, so:
[tex]y=2e^{0}[/tex]
We need to remember that any number elevated or powered to 0 is equal to 1, so:
[tex]y=2*1=2[/tex]
We have that the function intercepts the y-axis at y equal to 2, or the point (0,2).
Finding the x-axis intercept, we need to make "y" equal to 0, so:
[tex]y=2e^{x}[/tex]
[tex]0=2e^{x}[/tex]
[tex]Ln(0)=Ln(2e^{x})[/tex]
Now, since the natural logarithm of "0" does not exist in the real numbers, we can see that there is not x-axis intercept for this function.
Hence, the first option shows the graph of the given function.

Which expression is a factor of 12x2 + 29x – 8?
x – 8
2x – 1
3x + 8
4x + 1
Answer:
3x + 8
Step-by-step explanation:
Please use the symbol " ^ " to indicate exponentiation: 12x^2 + 29x – 8.
To answer this question, try dividing this 12x^2 + 29x – 8 by each of the given possible factors, one by one. If the end result is a zero remainder, that indicates that the particular factor is in fact a factor of 12x^2 + 29x – 8.
Alternatively, use synthetic division; if the end result is zero, then you have identified a root of 12x^2 + 29x – 8, as well as a factor.
Let's focus on x - 8: Is this a factor? Is 8 a root? Set up synthetic division as follows:
8 ) 12 29 -8
96 1000
-----------------
12 125 992
The non-zero remainder (992) indicates that 8 is not a root of 12x^2 + 29x – 8, and that x - 8 is not a factor.
Continuing onto the next given possible factor, 2x - 1, we set this = to 0 and solve for x, obtaining x = 1/2. Use synthetic division again:
1/2 ) 12 29 -8
6 35/2
------------------------
12 35 19/2 No, 1/2 is not a root and
2x - 1 is not a factor of 12x^2 + 29x – 8.
Try possible root x = -8/3:
-8/3 ) 12 29 -8
-32 8
----------------------------
12 -3 0
This zero remainder tells us that 3x + 8 is a factor of 12x^2 + 29x – 8.

Answer:
The second option
Step-by-step explanation:
4x - 2 > 6x + 8
add 2 to both sides
4x - 2 + 2 > 6x + 8 + 2
2 cancel -2 and it remains
4x > 6x + 10
Now, subtract 6x from both sides
4x -6x > 6x -6x + 10
it remains
-2x > 10
divide via by -2
x > 10/-2
x < -5
