The amount of total distance walked (in miles) has walked by Eric in a man made circular lake is 62.8 miles.
A circle's circumference is the length of its perimeter. The circumference of a circle can be calculated using length units such as centimeters, meters, or kilometers by opening a circle and measuring the boundary in the same way that we would measure a straight line.
Let's now discover the components of circumference. The three most crucial components of a circle are those three.
Center: The circle's center is a point that is set apart from the other points on the circumference by a predetermined amount.Diameter: The diameter is the distance across the circle that must pass through the center; it is a line that must meet the circumference at both ends.Radius: The radius of a circle is the distance a circle's center is from any point along its perimeter.Circumference = D*π
Total distance walked two times = 2.C
=2* D* π
=2x10x3.14
=62.8 miles

If angle b is two more than three times angle c, angle b and c are complimentary what is the measure of each angle
Step-by-step explanation:
"∠B is 2 more than 3 times the measure of ∠C" translates into B = 3C + 2....(1)
"...∠B and ∠C are complementary angles" translates to B + C = 90...............(2)
Now, all that's left to do is to solve for B and C. So, we'll take equation (1) and substitute it into equation (2) as follows:
(3C + 2) + C = 90
4C + 2 = 90
4C = 88
C = 22
Plugging C = 22 back into either equation (1) or (2) gives us
B = 90 - 22 = 68 (or B = 3(22) + 2 = 68)
Thus, ∠B = 68º; ∠C = 22º
Write y=2/5x−2 in standard form.
Answer:
2x - 5y = 10
Step-by-step explanation:
the equation of a line in standard form is
Ax + By = C ( A is a positive integer and B, C are integers )
given
y = [tex]\frac{2}{5}[/tex] x - 2 ( multiply through by 5 to clear the fraction )

distinct vertices of an octagon are chosen at random. what is the probability that they are adjacent?
If distinct vertices of an octagon are chosen at random , then the probability that they are adjacent is 2/7 .
An Octagon has 8 vertices, so there are 8 possible vertices to choose from. To find the probability that two chosen vertices are adjacent, we need to determine the number of ways in which two adjacent vertices can be chosen,
Since there are 8 vertices and each vertex has 2 adjacent vertices,
The total number of pairs of vertices in octagon is = ⁸C₂ = 28;
the possible Adjacent pairs are : {(1,8),(1,2),(2,3),(3,4),(4,5),(5,6),(6,7),(7,8)} ;
So , probability of vertices being adjacent is = 8/28 ;
Simplifying further , we get ;
Probability ⇒ 2/7 .
Therefore , the probability that vertices are adjacent is 2/7 .

consider a function with three variables: a, b, c. convert to sum-of-minterms form:
The sum-of-minterms form of the function f(a,b,c) = a'b + ac is (a'b + ac).
To convert a function with three variables to sum-of-minterms form, we first need to determine the truth table of the function, which lists all possible combinations of inputs and the corresponding outputs. Then, we identify the minterms (i.e., combinations of inputs that result in a 1 output) and represent each minterm as a binary number. The sum-of-minterms form of the function is then the sum of all the binary numbers representing the minterms.
For example, consider the function f(a,b,c) = a'b + ac. (The truth table for this function is attached below)
From the truth table, we can see that the minterms are (0,1,1) and (1,0,1), which can be represented as binary numbers 011 and 101, respectively. The sum-of-minterms form of the function is then:
f(a,b,c) = 011 + 101 = (a'b + ac)
So, the sum-of-minterms form of the function f(a,b,c) = a'b + ac is (a'b + ac).

if 0≤b≤2, for what value of b is ∫b0cos(ex)dx a minimum?
The value of b for which ∫b0cos(ex)dx is minimum is π/2e..
To find the value of b for which the definite integral ∫b0cos(ex)dx is a minimum, we can find the critical points (i.e. local extrema) of the integrand cos(ex) in the interval [0, 2].
Since cos(ex) is a periodic function with period 2π/e, it suffices to consider the interval [0, 2π/e]. In this interval, cos(ex) has its maximum value of 1 at x = 0, and its minimum value of -1 at x = π/2e and x = 3π/2e.
Since e is positive, the function cos(ex) is increasing on the interval [0, π/2e) and decreasing on the interval (π/2e, π/e].
Therefore, if b is in the interval [0, π/2e), the integral is minimized when b = 0. If b is in the interval [π/2e, π/e], the integral is minimized when b = π/2e.
Since the maximum value of b is 2, and 2 < π/e, it follows that the integral ∫b0cos(ex)dx is minimized when b = π/2e.

use property 8 to estimate the value of the integral ∫1147xdx.
Using property 8 and the midpoint rule, we have estimated the value of the integral ∫1147xdx to be approximately 14.
Property 8 of the definite integral states that if a < b and 0 < c < d, then:
∫baf(x)dx = ∫dcf(x)dx - ∫caf(x)dx
We can use this property to estimate the value of the integral ∫1147xdx. Let's choose c = 1 and d = 4, so that 0 < c < d and a < b. Then:
∫1147xdx = ∫447xdx - ∫11x dx
Next, we can use a numerical method, such as the midpoint rule or trapezoidal rule, to estimate the value of each of the integrals on the right side of the equation.
For example, using the midpoint rule with n = 4 subintervals for each integral:
∫447xdx ≈ (4 - 4/2) + (4 - 3/2) + (4 - 2/2) + (4 - 1/2) = 4 + 4 + 4 + 4 = 16
∫11x dx ≈ (1 - 1/2) + (1 - 2/2) = 1 + 1 = 2
So, our estimate of ∫1147xdx becomes:
∫1147xdx ≈ 16 - 2 = 14
Therefore, using property 8 and the midpoint rule, we have estimated the value of the integral ∫1147xdx to be approximately 14.

The perimeter of the actual triangle is 74 and option D is the correct answer.
What is scale factor?The scale factor is the difference in size between the original item's scale and that of the new object, which is a representation of it (bigger or smaller).
Given that the scaled dimension of the triangular face has the following dimensions:
PQ = 12
QR = PQ(1 + 25/100) = 12(125/100) = 15
PR = 2/3 (QR) = 2/3 (15) = 10
The scaling factor is 1/2 hence the actual dimensions of the triangle would be:
Original segments (1/2) = Scaled segment
Scaled (2) = Original
Using the above we have:
PQ = (12)(2) = 24
QR = (15)(2) = 30
PR =(10) (2) = 20
