What is exponential function?As the name suggests, the exponential function contains an exponent. Note, however, that the exponential function has a constant as its base and a variable as its exponent, not vice versa (if a function has a variable as its base and a constant as its exponent, it is a power function). The exponential function can be in one of the following forms:
Definition of exponential function
In mathematics, an exponential function is a function of the form f(x) = aˣ. where "x" is a variable and "a" is a constant called the base of the function, which must be greater than 0.
Given, exponential function
f(x) = (1/4)4ˣ
exponential function is defined for x∈R
Putting x = 0
f(0) = (1/4)4⁰
f(0) = 1/4
Point on curve is (0,1/4)
Putting x = 1
f(1) = (1/4)4¹
f(1) = (1/4)4
f(1) = 1
Point on curve is (1,1)
Putting x = 2
f(2) = (1/4)4²
f(2) = (1/4)16
f(2) = 4
Point on curve is (2,4)
Putting x = 3
f(3) = (1/4)4³
f(3) = (1/4)64
f(3) = 16
Point on curve is (3,16)
Point (0, 1/4), (1, 1), (2, 4), (3, 16) can be used to draw graph of the function.
Hence, graph of the function is drawn as follows.

What is the product of 5.2×104 and 1.3×10-2?
Answer:
551.8
Step-by-step explanation:
5.2\times 104 is 540.8
1.3\times 10-2 is 11
540.8 + 11 =551.8
Answer:
The answer is 676.
Step-by-step explanation:
I think you mean 5.2 multiplied by [tex]10^{4}[/tex], and 1.3 multiplied by [tex]10^{-2}[/tex].
Or do you mean 5.2 multiplied by 104 and 1.3 multiplied by 10 then subtract 2? Not really clear, but I'm going to go with the first option.
5.2 * [tex]10^{4}[/tex] = 52,000
1.3 * [tex]10^{-2}[/tex] = 0.013
52,000 * 0.013 = 676
The answer is 676.

A delivery truck is transporting boxes of two sizes: large and small. The combined welght of a large box and a small box is 85 pounds. The truck is transporting
70 large boxes and 50 small boxes. If the truck is carrying a total of 5350 pounds in boxes, how much does each type of box weigh?
9514 1404 393
Answer:
large: 55 lbsmall: 30 lbStep-by-step explanation:
Let x and y represent the weights of the large and small boxes, respectively. The problem statement gives rise to the system of equations ...
x + y = 85 . . . . . combined weight of a large and small box
70x +50y = 5350 . . . . combined weight of 70 large and 50 small boxes
We can subtract 50 times the first equation from the second to find the weight of a large box.
(70x +50y) -50(x +y) = (5350) -50(85)
20x = 1100 . . . . simplify
x = 55 . . . . . . . divide by 20
Using this in the first equation, we can find the weight of a small box.
55 +y = 85
y = 30 . . . . . . . subtract 55
A large box weighs 55 pounds; a small box weighs 30 pounds.

A sample of 46 observations is selected from one population with a population standard deviation
of 4.1. The sample mean is 102.0. A sample of 48 observations is selected from a second
population with a population standard deviation of 5.8. The sample mean is 100.1. Using the 0.05
significance level, is there a difference between the two samples?
Answer:
there is no significant evidence to conclude that there is difference between the two samples.
Step-by-step explanation:
Given :
x1 = 102 ; σ1 = 4.1 ; n1 = 46
x2 = 100.1 ; σ2 = 5.8 ; n2 = 48
H0 : μ1 = μ2
H0 : μ1 ≠ μ2
The test statistic :
The test statistic :
(x1 - x2) / sqrt[(σ1²/n1 + σ2²/n2)]
(102 - 100) / sqrt[(4.1²/46 + 5.8²/48)]
2 / 1.0326025
Test statistic = 1.937
The Pvalue from test statistic score ;
Pvalue = 0.052745
Pvalue > α ; Fail to reject the null ; Hence, there is no significant evidence to conclude that there is difference between the two samples.
A farmer finds there is a linear relationship between the number of bean stalks, n, she plants and the yield, y, each plant produces (in ounces). When she plants 30 stalks, each plant yields 30 oz of beans. When she plants 34 stalks, each plant produces 28 oz of beans. Find an equation that gives the yield y when n stalks are planted.
Answer:
[tex]y = -\frac{1}{2}n + 15[/tex]
Step-by-step explanation:
Linear equation:
A linear equation has the following format:
[tex]y(n) = an + b[/tex]
In which a is the slope and b is the y-intercept.
When she plants 30 stalks, each plant yields 30 oz of beans. When she plants 34 stalks, each plant produces 28 oz of beans.
This means that we have these following two points: (30,30) and (34,28).
Finding the slope:
When we have two points, the slope is given by the change in the output y divided by the change in the input n.
Change in the output: 30 - 28 = 2.
Change in the input: 30 - 34 = -4. So
[tex]a = \frac{2}{-4} = -\frac{1}{2}[/tex]
So
[tex]y = -\frac{1}{2}n + b[/tex]
Finding b:
When [tex]n = 30, y = 30[/tex]. We replace this into the equation to find b. So
[tex]y = -\frac{1}{2}n + b[/tex]
[tex]b = -\frac{1}{2}(30) + 30[/tex]
[tex]b = -15 + 30 = 15[/tex]
So
[tex]y = -\frac{1}{2}n + 15[/tex]

solve consult limit n·(e^-n)
Answer:
The value of the limit is 0.
Step-by-step explanation:
We are given the following limit:
[tex]\lim_{n \rightarrow \infty} ne^{-n}[/tex]
Simplifying the function:
[tex]\lim_{n \rightarrow \infty} \frac{n}{e^{n}}[/tex]
Replacing infinity at the numerator and denominator, we get infinity divided by infinity. Thus, L'Hospital Theorem can be applied, which means that we find the limit of the derivative of the numerator and the denominator.
Derivative of n is 1, of [tex]e^n[/tex] is [tex]e^n[/tex]
Then
[tex]\lim_{n \rightarrow \infty} \frac{n}{e^{n}} = \lim_{n \rightarrow \infty} \frac{1}{e^{n}} = \frac{1}{\infty} = 0[/tex]
The value of the limit is 0.

The dean of the UTC Engineering School at a small Florida college wishes to determine whether the grade-point average (GPA) of a graduating student can be used to predict the graduate's starting salary. More specifically, the dean wants to know whether higher GPAs lead to higher starting salaries. Records for 23 of last year's Engineering School graduates are selected at random, and data on GPA and starting salary ( in $thousands) for each graduate were used to fit the model The dependent variable is____________________________.
Answer:
grade-point average (GPA).
Step-by-step explanation:
The Independent variable may be explained as the variable which is used to manipulate the variable to be predicted. The Independent variable also called the predictor variable takes up several input values in other to observe how the predicted variable changes due to this independent variable. In the scenario described above, the independent variable is the Grade - point average, as it is used to make prediction or manipulate the value of the starting salary earned by a graduate. The starting salary earned is the predicted variable or dependent variable in this scenario.

Dennis walks from (–5, –2) to (–5, 5) on the map. Which expression represents the distance that he walked? |-2| + |5| |-5 + 5| |-2| - |5| |-5| + |-5|
Answer:
|-2| + |5|
Step-by-step explanation:
Dennis walks from (–5, –2) to (–5, 5) on the map.
Point on the format (x,y). On the x-coordinate, he stayed at the same position, x = -5, so it does not enter the distance calculation.
On the y-coordinate, he went from -2 to 5, so the distance is of:
[tex]d = 5 - (-2) = 5 + 2 = |5| + |2| = |5| + |-2| = 7[/tex]
So the correct option is |-2| + |5|

We have to convert it into Single logarithm.
What is Logarithm?Logarithm is a quantity representing the power to which a fixed number (the base) must be raised to produce a given number.
[tex]log_{b} (b^{x} ) = x[/tex]
According to the question, We can write the given statement in the mathematical form as follows -
f(x) = [tex]3\;log_{2} (x )-[log_{2} (3) -log_{2} (x+4)][/tex]
Using the property of logarithm -
log (A) - log(B) = log ([tex]\frac{A}{B}[/tex]), we get -
f(x) = [tex]3\;log_{2} (x )-log_{2} (\frac{3}{x+4} )[/tex]
Using the property of logarithm -
[tex]a\;log (b) = log(b^{a})[/tex]
f(x) = [tex]log_{2} (x^{3} )-log_{2} (\frac{3}{x+4} )[/tex]
f(x) = [tex]log_{2} (\frac{x^{3}}{\frac{3}{x+4}} )[/tex]
f(x) = [tex]log_{2} (\frac{x^{3} (x+4)}{3}})[/tex]
Hence, the simplified expression is - f(x) = [tex]log_{2} (\frac{x^{3} (x+4)}{3}})[/tex]

Answer:
A) -1/2
Step-by-step explanation:
the slope is defined by the ratio of y/x.
that means that for a change of a certain number of units in x, y changes this number of units.
e.g. a slope of 5/3 means, if x changes by 3 units, y changes by 5.
the graphic shows a line that goes "down" with increasing x.
that means the slope is negative.
that eliminates C and D.
and we see that when x increases by 2 units, y decreases by 1 unit.
that means the slope is -1/2.

9514 1404 393
Answer:
perimeter: 22.81 unitsarea: 24 square unitsStep-by-step explanation:
The lengths of the sides can be found using the distance formula.
d = √((x2 -x1)^2 +(y2 -y1)^2)
AC = √((0 -(-2))^2 +(8 -2)^2) = √(4+36) = 2√10
BC = √((0 -6)^2 +(8 -2)^2) = √(36+36) = 6√2
The distance AB is the difference of the x-coordinates of the points: 6-(-2) = 8.
Then the perimeter is ...
P = a + b + c = 6√2 +2√10 +8 = 8.49 +6.32 +8 = 22.81 . . . units

I made a fort by two boxes. The first box is 4 meters long, 8 meters wide, and 8 meters high. The second box is 2 meters long, 7 meters wide, and 1 meter high. How many cubic meters of space does my fort have?
Answer:
242 m³ of space is there in the fort.
Step-by-step explanation:
Given that,
The dimensions of first box is 4 meters long, 8 meters wide, and 8 meters high.
The dimensions of the second box is 2 meters long, 7 meters wide, and 1 meter high.
Space left = Volume of first box - volume of second box
= (4)(8)(8) - 2(7)(1)
= 242 m³
So, 242 m³ of space is there in the fort.
