Answer:

42.59 km

Step-by-step explanation:

Total distance = 17.9 + 6.03 + 15.66 + 3 = 42.59

Answer:

42.59 km

Step-by-step explanation:

When a question tells you to find the total of something it is usually means you need to add to add decimals you align the decimals and if a number doesn't have a decimal you add .0 on the end then line it up. It also might help to add a 0 in empty spots . Then you move the decimal to the same place in the solution and add like normal.

Answer:

3b/2 + 3

Step-by-step explanation:

The formula to calculate perimeter of rectangle is 2l + 2w

The length is half the width so length is 1/2 (b/2 +1), which when simplified is b/4 + 1/2

Using the formula to calculate perimeter you can substitute and calculate

p= 2l + 2w

p= 2(b/4 + 1/2) + 2(b/2 + 1)

p= 2b/4 +2/2 + 2b/2 +2

p= 1/2b + 1 + b + 2

p= 3/2b + 3

Simplified it's 3b/2 +3

ok done. Thank to me :>

The quadratic equation 2a^2 = -6 + 8a has two solutions: a = 3 and a = 1.

To solve the quadratic equation 2a^2 = -6 + 8a, we need to rearrange it into standard quadratic form, which is ax^2 + bx + c = 0, where a, b, and c are coefficients.

Step 1: Move all the terms to one side of the equation to set it equal to zero:

2a^2 - 8a + 6 = 0

Step 2: The equation is now in standard quadratic form, so we can apply the quadratic formula to find the solutions for 'a':

a = (-b ± √(b^2 - 4ac))/(2a)

Comparing with our equation, we have:

a = (-(-8) ± √((-8)^2 - 4(2)(6)))/(2(2))

Simplifying further:

a = (8 ± √(64 - 48))/(4)

a = (8 ± √16)/(4)

a = (8 ± 4)/(4)

Now, we can calculate the two possible solutions:

a1 = (8 + 4)/(4) = 12/4 = 3

a2 = (8 - 4)/(4) = 4/4 = 1

Therefore, the quadratic equation 2a^2 = -6 + 8a has two solutions: a = 3 and a = 1.

Answer:

140,000

Step-by-step explanation:

We know that the number is 143,699.

We are asked to round to the nearest ten thousand, which is the number bolded:

143,699

This means we have to look at the number to the right of the 4, which is 3.  If this number is below "5", then we round down to get 140,000.  

If this number was (and it's NOT) above "5" or "5" itself, we would round up to 150,000.  

Since "3" is below "5", we would round down to 140,000.

Bayes' rule involves three main elements:

Prior Probability: The prior probability represents our initial belief or knowledge about the probability of an event or hypothesis before considering any new evidence. It is typically denoted as P(H), where H represents the hypothesis or event. The prior probability is based on previous experience, background information, or subjective assessments.

Likelihood of the Evidence: The likelihood is the probability of observing the given evidence (E) assuming that the hypothesis (H) is true. It is denoted as P(E|H), where P(E|H) represents the probability of the evidence E given the hypothesis H. The likelihood quantifies how well the hypothesis explains the observed data or evidence.

Posterior Probability: The posterior probability represents the updated probability of the hypothesis or event given the observed evidence. It is denoted as P(H|E), where P(H|E) represents the probability of the hypothesis H given the evidence E. The posterior probability is the main result of applying Bayes' rule and combines the prior probability with the likelihood of the evidence.

Mathematically, Bayes' rule is expressed as:

P(H|E) = (P(E|H) * P(H)) / P(E)

Here, P(H|E) is the posterior probability, P(E|H) is the likelihood, P(H) is the prior probability, and P(E) is the probability of the evidence.

Answer:

A) sin(theta) = cos(theta).

Explanation:

The third quadrant is the quadrant where the angle is between 180 and 270 degrees.

Given that the angle 6 is in the third quadrant, we know that:

- sin(6) < 0 (negative in the y-axis)

- cos(6) < 0 (negative in the x-axis)

- tan(6) > 0 (positive in the 2nd quadrant)

- csc(6) < 0 (negative in the y-axis)

With this information, we can determine which of the given statements could never be true:

A) sin(theta) = cos(theta)

This statement is not true for any angle in any quadrant, since sine and cosine functions are different except for certain special angles.

B) tan(theta) < 0

This statement is true for angles between 180 and 270 degrees, including angle 6.

C) cos(theta) = cos(- theta)

This statement is true for any angle, since the cosine function is an even function.

D) csc(theta) < 0

This statement is true for angles between 180 and 270 degrees, including angle 6.

Therefore, the statement that could never be true is A) sin(theta) = cos(theta).

Answer:

Coordinate of Point A is (-11, 15)

Step-by-step explanation:

M -- (-3, 7)

B -- (5, -1)

Therefore, (5 + x)/2  = -3

x = -11

(-1 + y)/2 = 7

y = 15

Therefore Point A is (-11, 15)

Answer:

Solution given;

mid point (x,y)=(-3,7)

coordinate of B(x1,y1)=(5,-1)

coordinate of A(x2,y2)=(a,b)

we have

midpoint (x,y)={(x1+x2)/2,(y1+y2)/2}

(-3,7)={(a+5)/2,(b-1)/2}

equating corresponding value

(a+5)/2=-3

a+5=-6

a=-6-5

a=-11

again

7=(b-1)/2

b-1=14

b=14+1

b=15

So

coordinate of the point A is (-11,15).

Answer:

number 5:4/12

#6: 25/45

#7: 26/44

#8: 52/30

Step-by-step explanation:

Answer:

5) 1/3=x/12

12=3x

3x=12 (divide both sides)

12 divided by 3 = 4

therefore, x = 4

6) 5/9=25/y (cross multiply the numbers)

after cross multiplying you should get: 5y=225

divide both sides to get 45

therefore, y = 45

7) 26/z = 13/22 (cross multiply numbers)

after cross multiplying, you should get: 572=13z (swap the numbers)

after swapping the number, you should get: 13z=572 (divide both sides)

after dividing you should get 44

therefore, z = 44

8) b/30 = 2.6/1.5 (simplify expression)

after simplifying you should get: b/30=26/15 (cross multiply after)

after cross multiplying you should get: 15b = 780 (divide both sides)

after dividing both sides, you should get: 52

therefore, b = 52

The area of the region d is 1 square unit.

Given that the region d is bounded by y=x^3, y=x^3+1.The area of the region d can be calculated using a double integral. We know that the area is given by A= ∬d dA.

Here, dA is the differential area element, which can be represented as dA=dxdy.

We can write the above equation asA= ∫∫d dxdy. From the given bounds, we know that the limits of integration for y are x^3 to x^3+1, and for x, the limits are from 0 to 1.

\(Thus,A= ∫0^1∫x³^(x³+1) dxdy.\)

Now, we can perform the integration with respect to x and then with respect to y.

\(A= ∫0^1 [(x³+1)-(x³)] dy= ∫0^1 (1) dy= 1\)

The required area is 1 square unit.

Step-by-step explanation:

(a) The length of wire that should be used for the square in order to maximize the total area is 9 meters.

(b) Using the same 9 meters of wire for the square will result in the minimum total area as well as the maximum total area.

(a) To maximize the total area, we need to use as much wire as possible for the square and as little as possible for the triangle. Let x be the length of wire used for the square, then the length of wire used for the triangle is 9 - x.

For the square, we have:

4s = x, where s is the side length of the square.

For the equilateral triangle, we have:

3t = 9 - x, where t is the side length of the equilateral triangle.

Solving for x in terms of s and t, we get:

x = 4s and x = 9 - 3t/2.

Substituting x = 4s into x = 9 - 3t/2, we get:

4s = 9 - 3t/2

8s = 18 - 3t

t = (18 - 8s)/3

The area of the square is given by A = s^2, and the area of the equilateral triangle is given by A = (\(\sqrt{3}\)/4)t^2.

Substituting t = (18 - 8s)/3, we get:

A = (\(\sqrt{3}\)/4)((18 - 8s)/3)^2

To maximize the total area, we need to maximize A, which is a function of s. Taking the derivative of A with respect to s, we get:

dA/ds = -4\(\sqrt{3}\)(4s-9)/27

Setting dA/ds = 0, we get:

4s - 9 = 0

Solving for s, we get:

s = 9/4

Therefore, the length of wire that should be used for the square in order to maximize the total area is:

x = 4s = 9 meters.

(b) To minimize the total area, we need to use as little wire as possible for the square and as much as possible for the triangle. Let x be the length of wire used for the square, then the length of wire used for the triangle is 9 - x.

Using the same equations as in part (a), we get:

t = (18 - 8s)/3

A = (\(\sqrt{3}\)/4)((18 - 8s)/3)^2

Taking the derivative of A with respect to s, we get:

\(dA/ds = -4\sqrt{3}(4s-9)/27\)

Setting dA/ds = 0, we get:

4s - 9 = 0

Solving for s, we get:

s = 9/4

This is the same value as in part (a), which means that using 9 meters of wire for the square will result in the minimum total area as well as the maximum total area.
