Answer:

m = -3

Step-by-step explanation:

We Know

Slope = rise/run or (y2 - y1) / (x2 - x1)

Pick 2 points (0,15) (2,9)

We see the y decrease by 6, and the x increase by 2, so the slope is

m = -6/2 = -3

So, the slope of the line representing the data is -3.

Answer:

134° + (2x)° = 180°

(2x)° = 46°

x = 23

So angles 1, 2, 3, and 4 all measure 23°.

If the commission rate is ​%6.5 for the real estate agency, the real estate agency made $20,475 on the house. The agent earned $4,095 in commission.

First, let's determine the commission earned by the real estate agency. To do this, we'll multiply the house price ($315,000) by the commission rate (6.5%).

$315,000 * 6.5% = $20,475

The real estate agency made $20,475 on the house.

Next, let's determine the commission earned by the agent. We'll multiply the commission earned by the real estate agency ($20,475) by the agent's commission rate (20%).

$20,475 * 20% = $4,095

The agent earned $4,095 in commission.

So, the real estate agency made $20,475 on the house, and the agent earned $4,095 in commission.

The expression equation y = sin x + cos x / csc x can be simplified to y = cos x sin^2 x + cos^2 x.

To simplify the expression, we can first replace csc x with 1/sin x. This gives us y = sin x cos x + cos^2 x / sin x.

Next, we can factor out cos x from the numerator of the second term to get y = cos x (sin x + cos x) / sin x.

Using the identity sin^2 x + cos^2 x = 1, we can replace sin^2 x with 1 - cos^2 x in the numerator of the first term. This gives us y = cos x (1 - cos^2 x) / sin x + cos x (sin x + cos x) / sin x.

Simplifying the expression further, we get y = cos x (1 - cos^2 x + sin x + cos x) / sin x.

Finally, we can combine the terms in the numerator to get y = cos x (sin^2 x + 2cos x sin x + 1) / sin x.

Using the identity sin^2 x = 1 - cos^2 x, we get y = cos x (3cos^2 x + 2cos x) / sin x.

Simplifying the expression, we arrive at y = cos x (cos x + 2) (3cos x + 2) / sin x.

Therefore, the simplified expression is y = cos x sin^2 x + cos^2 x, which can also be written as y = cos x (sin x)^2 + cos^2 x.

To the nearest tenth of an inch, the length of the shorter leg of each right triangle will be 2.7 inches.

A triangle is a polygon with three sides and three angles. The sum of the three angles in a triangle always adds up to 180 degrees. There are many different types of triangles, including equilateral triangles (where all three sides are equal in length and all three angles are 60 degrees), isosceles triangles (where two sides are equal in length and two angles are equal in measure), and scalene triangles (where no sides are equal in length and no angles are equal in measure).

Let x be the length of the shorter leg of each right triangle. Then, the longer leg will be twice as long, so its length will be 2x. Using the Pythagorean theorem, we can write:

x² + (2x)² = 6²

Simplifying and solving for x, we get:

x² + 4x² = 36

5x² = 36

x² = 7.2

x ≈ 2.7

Therefore, to the nearest tenth of an inch, the length of the shorter leg of each right triangle will be 2.7 inches.

Note that the first coordinate of M is -1. (Option D)

Given :- coordinates of F = (-4,-2) = (x1,y1)

coordinates  of G = (2,-2) = (x2,y2)

coordinates of P = (2,-8) = (x3,y3)

and distance between point M and P is half of the distance between FG

To find :- first coordinate of point M

solution :- let the coordinate of M be (x4,y4)

as we know that distance between of the opposite point of parallel line segments are equal

so, second coordinate of M = -8

now by distance formula

FG = √(x2-x1)² + (y2-y1²)

= √[2-(-4)]² + [-2-(-2)]²

= √(2+4)² + (2-2)²

= √(6)² + (0)²

=√36

F G = 6

so, distance between point M and P = 1/2 × F G

= 1/2 × 6

= 3units

again, by distance formula

MP = √(x3-x⁴)² + (y3-y4)²

3 = √(2-x⁴)² + [-8-(-8)]²

squaring on both side

(3)² = (√(2-x⁴)² + [-8-(-8)]²)²

9 = (2-x⁴)² + [-8-(-8)]²

9 = (2-x⁴)²+(0)²

9 = (2-x⁴)²

The divergence of F is 2y cos(z) + eˣ cos(z) + 3xe³, and the curl of F is -eˣcos(z)i - 3xe³j + (eˣsin(z) + 2cos(z))k.

To find the divergence and curl of the vector field F(x, y, z) = 2y cos(z)i + eˣ sin(z)j + xe³k, we need to apply the appropriate operators.

The divergence of F is given by:

div F = ∇ · F = (∂/∂x)i + (∂/∂y)j + (∂/∂z)k · (2y cos(z)i + eˣ sin(z)j + xe³k)

where ∇ is the del operator.

Calculating the dot product, we get:

div F = 2y cos(z) + eˣ cos(z) + 3xe³

Therefore, the divergence of F is:

div F = 2y cos(z) + eˣ cos(z) + 3xe³

Now, let's find the curl of F. The curl of F is given by:

curl F = ∇ × F = ( (∂/∂y)(xe³) - (∂/∂z)(eˣsin(z)) )i - ( (∂/∂x)(2ycos(z)) - (∂/∂z)(xe³) )j + ( (∂/∂x)(eˣsin(z)) - (∂/∂y)(2ycos(z)) )k

Calculating the partial derivatives, we get:

(∂/∂y)(xe³) = 0

(∂/∂z)(eˣsin(z)) = eˣcos(z)

(∂/∂x)(2ycos(z)) = 0

(∂/∂z)(xe³) = 3xe³

(∂/∂x)(eˣsin(z)) = eˣsin(z)

(∂/∂y)(2ycos(z)) = -2cos(z)

Substituting these values, we get:

curl F = (0 - eˣcos(z))i - (0 - 3xe³)j + (eˣsin(z) - (-2cos(z)))k

Simplifying, we get:

curl F = -eˣcos(z)i - 3xe³j + (eˣsin(z) + 2cos(z))k

Therefore, the divergence of F is 2y cos(z) + eˣ cos(z) + 3xe³, and the curl of F is -eˣcos(z)i - 3xe³j + (eˣsin(z) + 2cos(z))k.

The customer can choose from 21 different gifts if they want to order only 1 item, 138 different gifts if they want to order 2 items of different kinds, and 280 different gifts if they want to order 3 items of different kinds.

To find the different number of gifts, we use the fundamental counting principle, which states that the total number of ways to choose a sequence of items is equal to the product of the number of choices available for each item.

⇒ If a customer wants to order only 1 item, they can choose from:

10 varieties of "greeting-cards"

4 types of "fruit-baskets"

7 flower arrangements

So, total number of different gifts that can be created is: 10 + 4 + 7 = 21.

⇒ If a customer wants to order 2 items of different kinds, they can choose from:

10 varieties of greeting-cards and 4 types of fruit baskets :

(10 × 4 = 40 choices)

10 varieties of greeting cards and 7 flower arrangements :

(10 × 7 = 70 choices)

4 types of fruit-baskets and 7 flower arrangements :

(4 × 7 = 28 choices)

So, number of different gifts that can be created is: 40 + 70 + 28 = 138.

⇒ If a customer wants to order 3 items of different kinds, they can choose from:

If Shen drives fewer than 80 miles, the first plan will be cheaper. If he drives more than 80 miles, the second plan will be cheaper.

Let's denote the number of miles driven by "m".

Under the first plan, Shen will pay an initial fee of $40, and then an additional $0.30 for each mile driven. So the total cost, C1, can be expressed as:

C1 = 0.3m + 40

Under the second plan, Shen will not have to pay an initial fee, but he will be charged $0.80 for each mile driven. So the total cost, C2, can be expressed as:

C2 = 0.8m

To determine which plan is cheaper for a given number of miles driven, we can set the two expressions for cost equal to each other and solve for "m":

0.3m + 40 = 0.8m

Subtracting 0.3m from both sides, we get:

40 = 0.5m

Dividing both sides by 0.5, we get:

m = 80

So if Shen drives fewer than 80 miles, the first plan will be cheaper. If he drives more than 80 miles, the second plan will be cheaper.

It's worth noting that this assumes that Shen is only considering the cost of the rental when making his decision. If there are other factors he is considering, such as convenience or availability, he may choose a different plan even if it ends up being slightly more expensive.

Step-by-step explanation:

Let's use the formula for the perimeter of a rectangle, which is P = 2l + 2w, where P is the perimeter, l is the length, and w is the width.In this case, we have:P = 16 cm (given)

l = k cm (given)

w = 5 cm (given)Substituting these values into the formula, we get:

16 cm = 2(k cm) + 2(5 cm)

Simplifying, we get:

16 cm = 2k cm + 10 cm

Subtracting 10 cm from both sides, we get:6 cm = 2k cm

Dividing both sides by 2, we get:

3 cm = k

The probability of TJ pulling 2 white socks is 0.125 or 12.5%.

There are 16 socks in total, so the probability of the first sock being white is 6/16.

Since we are not replacing the first sock, there are now 15 socks left, including 5 white socks.

So the probability of the second sock being white, given that the first sock was white, is 5/15.

To find the probability of both events occurring, we multiply the probabilities:

P(white and white) = P(white on first draw) × P(white on second draw, given that the first was white)

P(white and white) = (6/16) × (5/15)

P(white and white) = 1/8

Let's consider the equation a⁴ + b⁴ + c⁴ + 54 = 11abc. Due to the fact that the total of four even numbers is also even, the left-hand side is always even. As a result, since 2 is the only even prime, one of the factors a, b, or c must be 2 for 11abc to likewise be even.

Let's examine each instance,

b⁴ + c⁴ - 22bc + 38 = 0

Since b and c are primes, they must be odd. Let b = 3 and c = 5, we have,

3⁴ + 5⁴ - 2235 + 38 = 0

81 + 625 - 330 + 38 = 0

Case 2: b = 2

Substituting b = 2 into the equation, we get,

a⁴ + c⁴ - 22ac + 70 = 0

Since a and c are primes, they must be odd. Let a = 3 and c = 5, we have,

Case 3: c = 2

Substituting c = 2 into the equation, we get,

a⁴ + b⁴ + 16 + 54 = 22ab

a⁴ + b⁴ - 22ab + 70 = 0

However, for any odd number x, x⁴ mod 16 = 1, which means that a⁴ and b⁴ are both corrosponds to 1 mod 16. So, as the conclusion, a = 3, b = 2, and c = 5.

Answer: 48 inches

Step-by-step explanation:

At the end of the weekend, Elisa had the most biscuits (168). So, the answer is (E) Elisa baked the most biscuits on Saturday.

To determine who baked the most biscuits on Saturday, we need to calculate how many biscuits each child had at the end of the weekend.

Anna had 24 biscuits, Berta had 25, Charlie had 26, David had 27, and Elisa had 28.

Let's start with the child who had twice as many biscuits as on Saturday. We can divide their total number of biscuits by 2 to get the number they had on Saturday.

If we try this calculation for each child, we find that only Elisa's total number of biscuits (28) is evenly divisible by 2. Therefore, Elisa must be the child who had twice as many biscuits as on Saturday, meaning she had 14 biscuits on Saturday.

We can use a similar process to determine how many biscuits each child had on Saturday:

- The child who had three times as many biscuits as on Saturday must have had a total of 42 biscuits, which means they had 14 biscuits on Saturday.
- The child who had four times as many biscuits as on Saturday must have had a total of 56 biscuits, which means they had 14 biscuits on Saturday.
- The child who had five times as many biscuits as on Saturday must have had a total of 70 biscuits, which means they had 14 biscuits on Saturday.
- The child who had six times as many biscuits as on Saturday must have had a total of 84 biscuits, which means they had 14 biscuits on Saturday.

Now we can add up the number of biscuits each child had on Saturday:

- Anna had 24 biscuits.
- Berta had 25 biscuits.
- Charlie had 26 biscuits.
- David had 27 biscuits.
- Elisa had 14 biscuits.

Therefore, David baked the most biscuits on Saturday with 27.
To determine who baked the most biscuits on Saturday, we need to consider the information given about the multiplication factors (twice, 3 times, 4 times, 5 times, and 6 times) and the initial number of biscuits baked by each child.

1. Anna baked 24 biscuits.
2. Berta baked 25 biscuits.
3. Charlie baked 26 biscuits.
4. David baked 27 biscuits.
5. Elisa baked 28 biscuits.

Now, let's apply the multiplication factors and see which child had the most biscuits at the end of the weekend:

1. Anna: 24 x 2 = 48
2. Berta: 25 x 3 = 75
3. Charlie: 26 x 4 = 104
4. David: 27 x 5 = 135
5. Elisa: 28 x 6 = 168

At the end of the weekend, Elisa had the most biscuits (168). So, the answer is (E) Elisa baked the most biscuits on Saturday.
