Which is an exponential decay function
F(x)= 0.2
The function F(x)=0.2F(x)=0.2 is not an exponential decay function. It is a constant function where the output value is always equal to 0.2, regardless of the input value xx.
An exponential decay function is typically in the form f(x)=a⋅bxf(x)=a⋅bx, where aa and bb are constants and bb is a value between 0 and 1. As xx increases, the exponential decay function decreases exponentially.
For example, an exponential decay function could be f(x)=0.2⋅(0.5)xf(x)=0.2⋅(0.5)x, where the base 0.50.5 represents the decay factor. As xx increases, the value of the function decreases rapidly.
In summary, an exponential decay function follows the pattern of decreasing values as xx increases, while the function F(x)=0.2F(x)=0.2 represents a constant value regardless of the input xx.

Suppose that y varies directly with x and y = 2 when x =16 write a direct variation equation that relates x and y
The equation of the direct variation is expressed as: y = 1/8x.
How to Write a Direct Variation Equation?The equation of a direct variation between two variables, say x and y, is expressed as y = kx, where k is the constant of proportionality, if y varies directly as x.
Therefore, substitute y = 2 and x = 16 into y = kx to find the value of k:
2 = k(16)
Divide both sides by 16
2/16 = k
1/8 = k
k = 1/8.
To write the equation of the direct variation, substitute k = 1/8 into y = kx:
y = 1/8x.

A. 345.4 feet
B. 172.7 feet
C. 86.35 feet
D. 2,323.1 feet
The approximate distance around the outside of the circular field is the circumference = 172.7 feet and the correct option is B.
How to evaluate for the circumference of a circleTo calculate the circumference of a circle, multiply the diameter of the circle with π (pi). The circumference can also be calculated by multiplying 2×radius with pi (π = 3.14).
We shall derive the approximate distance around the outside of the circular field by calculating for the circumference as follows:
Radius of the circular feild = 27.5
circumference of the circular feild = 2 × 27.5 feet × 3.14
circumference of the circular feild = 55 feet × 3.14
circumference of the circular feild = 172.7 feet.
Therefore, the approximate distance around the outside of the circular field is derived as the circumference which is equal to 172.7 feet.

Solve following modular equation, using reverse Euclidean algorithm:
\((5 * x) mod 91 = 32\)
The required reverse Euclidean algorithm is the solution to the modular equation (5x) mod 91 is
x = 6(mod 91).
Given that (5*x) mod 91 =32.
To solve the modular equation (5*x) mod 91 =32 using reverse Euclidean algorithm is to find the modular inverse of 5 modulo 91.
Consider (5*x) mod 91 =32.
5x = 32(mod 91)
Apply the Euclidean algorithm to find GCD of 5 and 91 is
91 = 18 * 5 + 1.
Rewrite it in congruence form,
1 = 91 - 18 *5
On simplifying the equation,
1 = 91 (mod 5)
The modular inverse of 5 modulo 91 is 18.
Multiply equation by 18 on both sides,
90x = 576 (mod91)
To obtain the smallest positive solution,
91:576 = 6 (mod 91)
Divide both sides by the coefficient of x:
x = 6 * 90^(-1).
Apply the Euclidean algorithm,
91 = 1*90 + 1.
Simplify the equation,
1 + 1 mod (90)
The modular inverse of 90 modulo 91 is 1.
Substitute the modular inverse in the given question gives,
x = 6*1(mod 91)
x= 6 (mod91)
Therefore, the solution to the modular equation (5x) mod 91 is
x = 6(mod 91).

Identify the mean, median, mode, and range of the data set. 7, 6, 8, 12, 9, 13, 8
The mean is approximately 9, the median is 9, the mode is 8, and the range is 7.
To find the mean, we add up all the numbers in the data set and divide by the total number of numbers:
Mean = (7 + 6 + 8 + 12 + 9 + 13 + 8) / 7 = 63 / 7 ≈ 9
So the mean is approximately 9.
To find the median, we need to arrange the numbers in order from smallest to largest:
6, 7, 8, 8, 9, 12, 13
Since there are an odd number of values in the data set, the median is the middle value, which is 9.
To find the mode, we need to look for the value that occurs most frequently in the data set. In this case, 8 occurs twice, which is more than any other value, so the mode is 8.
To find the range, we need to subtract the smallest value from the largest value:
Range = largest value - smallest value = 13 - 6 = 7

2. Which is NOT a necessary characteristic of a tessellation?
O repeating pattern
O congruent shapes
Ono gaps or overlaps
O creating your own shape
Step-by-step explanation:
Creating your own shape is NOT a necessary characteristic of a tessellation. A tessellation is a repeating pattern of congruent shapes without gaps or overlaps. The shapes used in a tessellation can be any regular or irregular polygon, but they must be congruent to each other. Creating your own shape would result in a non-congruent shape and therefore would not meet the definition of a tessellation.
The answer would be D. Tessellation involves tiling and is a display of shapes fitted together on a surface, which means that tessellation does not only compose of one shape. It has to have a repeating pattern with no gaps. That can be achieved with a variety of shapes.

what is the property of 3x(5x7)=(3x5)7
The property you are referring to is called the associative property of multiplication. According to this property, when multiplying three numbers, the grouping of the numbers does not affect the result. In other words, you can change the grouping of the factors without changing the product.
In the equation you provided: 3x(5x7) = (3x5)7
The associative property allows us to group the factors in different ways without changing the result. So, whether we multiply 5 and 7 first, or multiply 3 and 5 first, the final product will be the same.

The y-intercept is D) 3
The slope is C) -1/3
Answer:
Slope: [C] -1/3
Y-intercept: [D] 3
Step-by-step explanation:
Part A:
What is the slope of line t?
How to Find Slope:
Find any two order pairs on the line.I will be using:(0,3) (6,1)Then using these two order pairs we substitute it to- \({{\frac{y_2-y_1}{x_2-x_1}}\) to find slope.
Knowing that:
(0,3) ⇒ 0 = x₁ and 3 = y₁
(6,1) ⇒ 6 = x₂ and 1 = y₂
Now, using \({{\frac{y_2-y_1}{x_2-x_1}}=m\) to find slope:
\({{\frac{y_2-y_1}{x_2-x_1}}\\\\= {{\frac{1-3}{6-0}}=-\frac{2}{6} =-\frac{1}{3}\)
As a result, the slope of line t is -1/3. Which means the answer is [C] -1/3.
Part B:
Since we already find slope. We can use slope intercept form to find y-intercept.
Slope intercept form ⇒ y = mx + b
Note - b - in slope intercept form is the y-intercept
Using any given ordered pairs. I will be using (0,3) and substitute into slope intercept form:
Knowing that; 0 = x and 3 = y.
Thus,
3 = (-1/3)(0) + b { -1/3 × 0 = 0}
3 = b
Hence, y-intercept of line b is 3. Which means the answer is [D] 3.
