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.

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.

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.

Answer:
y = 0.9
Step-by-step explanation:
1.05 + 0.7y = 3.5y - 1.47

The vertices of ABC are Al-2, 2), B6, 2), and 90, 8). The perimeter of ABC is
units, and its area is
square units.
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

The height of the triangle is the difference in y-values between vertex C and line AB: 8 -2 = 6. The area is given by the formula ...

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.
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|

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.

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 value 1r is a measure of how closely two variables vary together. B. The value 1r is the percent of the predicted values that equal the actual data values. C. The value 1r is the percent of the variation that is unexplained. D. The value 1r is the percent of variation of y that is explained by the relationship between x and y.
Answer:
D. The coefficient of determination is the ratio of the explained variation to the total variation.
C. The coefficient of determination is the percent of variation of y that is explained by the relationship between x and y
Step-by-step explanation:
The Coefficient of determination is the ratio of the explained variation in y to the total variation in y.
Coefficient of determination, r² ;
r² = explained variation / total variation
The coefficient of determination is the proportion of variation in y (predicted value) which is due to the regression line ; Hence, it is the percent of variation of y that is explained by the relationship between x and y.

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.

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]

How much total money would Annabelle have to pay for her family if she were to buy 6 snacks for everybody to share? How much would Annabelle have to pay if she bought x snacks for everybody to share?
Cost for 6 snacks:
Cost for x snacks:
Answer:
(a) $83 for 6 snacks
(b) [tex]y = 65 + 3x[/tex] --- for x snacks
Step-by-step explanation:
Given
Let:
[tex]n \to people[/tex]
[tex]ticket =\$13[/tex] --- per individual
[tex]snacks = \$3[/tex] --- per individual
Solving (a): Amount for 6 snacks
The amount paid (y) is:
[tex]y = ticket * n + snacks * 6[/tex] ---- because she bought 6 snacks
[tex]y = 13 * n + 3 * 6[/tex]
[tex]y = 13n + 18[/tex]
[tex]n = 5[/tex] ---- Annabelle and the 4 kids.
So:
[tex]y =13*5+18[/tex]
[tex]y =65+18[/tex]
[tex]y =83[/tex]
Solving (b): For x snacks
The amount paid (y) is:
[tex]y = ticket * n + snacks * x[/tex] ---- because she bought x snacks
[tex]y = 13* 5 + 3* x[/tex]
[tex]y = 65 + 3x[/tex]
