WHAT DOES THIS MEAN GIMME THE ANSWER

Answer:

(1,6)

Step-by-step explanation:

In order to reflect a point over a horizontal line, you need to count how many units it takes to reach that line (going vertically). Once you have that number, count that many units starting from that point on the line (again, going vertically), then that is your reflected point.

Counting from point Q to the line y = 2, it takes 4 units. So starting from that point on the line where I left off, I would count another 4 units, taking me to (1,6). The picture below explains it better visually.

The two real solutions to this quadratic equation are -2 and 3/2.

The Quadratic Formula is the most popular method for solving quadratic equations of the form ax²+bx+c=0. It is derived from the quadratic equation which states that if a, b, and c are real numbers, and a is not equal to zero, then the roots of the quadratic equation ax²+bx+c=0 can be determined by the following equation:

x = (-b ± √(b² - 4ac))/(2a)

The quadratic formula can be used to solve for the two real solutions of any quadratic equation. It works by determining the discriminant, which is the number under the square root in the equation. The discriminant is calculated by subtracting 4ac from b². The ± symbol indicates that there are two solutions, one with the plus sign and one with the minus sign.

For example, if we have a quadratic equation 2x²+5x-3=0, the discriminant can be calculated as follows:

b² - 4ac = (5)² - 4(2)(-3) = 25 + 24 = 49

The two solutions can then be found using the formula:

x = (-5 ± √49)/(2(2))

x = (-5 ± 7)/(4)

x = -2 or 3/2

Therefore, the two real solutions to this quadratic equation are -2 and 3/2.

Answer:

Step-by-step explanation:

To write a recursive sequence that represents the sequence defined by the explicit formula an = 10 + 4(n + 1), we need to find a recursive formula that relates each term in the sequence to the previous term.

We can start by noticing that the explicit formula for the first term (a1) is:

a1 = 10 + 4(1 + 1) = 18

To find the next term (a2), we substitute n = 2 into the explicit formula:

a2 = 10 + 4(2 + 1) = 22

To find the third term (a3), we substitute n = 3 into the explicit formula:

a3 = 10 + 4(3 + 1) = 26

We can see that each term in the sequence is obtained by adding 4 to the previous term. Therefore, we can define the recursive formula as follows:

a1 = 18

an+1 = an + 4

This recursive formula states that the first term of the sequence is 18, and that each subsequent term is obtained by adding 4 to the previous term. This recursive formula generates the same sequence as the original explicit formula, and can be used to calculate any term in the sequence.

The positive integer representing possible values for third side length of the triangle as per given measure of two side length are 45.

Two side length of a triangle be 'x' and 'y'

Side length 'x' = 23

Side length 'y' = 53

Third side length be 'n'

Using triangle inequality we have ,

x + y > n

⇒ 23 + 53 > n

⇒ 76 > n ___(1)

And x + n > y

⇒ 23 + n > 53

⇒ n > 53 - 23

⇒ n > 30 ___(2)

We know 'n' is a positive integer .

30 < n < 76

All the positive integer between 30 and 76 are possible values for 'n'.

Possible values are : 75 - 30 = 45

Therefore, there are 45 possible values for the third side of a triangle.

Step-by-step explanation:

The height of the kite is approximately 68.4 ft.

To solve the problem, we can use trigonometry. We know that the string is the hypotenuse of a right triangle, with the height of the kite as one of the legs. The angle of elevation, which is the angle between the string and the ground, is also given. We can use the tangent function to find the height of the kite:

tan(46°) = height / 94

Solving for height, we get:

height = 94 * tan(46°)

Using a calculator, we get:

height ≈ 68.4 ft

Therefore, the height of the kite is approximately 68.4 ft.

We use the given angle of elevation and the length of the string to set up a right triangle with the height of the kite as one of the legs. Then, we use the tangent function to relate the angle to the height of the kite. Finally, we solve for the height using a calculator and round to the nearest tenth as requested.

The expected value of the number of Republicans in the sample is 22.5 by using the concept of expected value.

The expected value is calculated by multiplying each possible outcome by its corresponding probability and summing them up.

In this case, we have a population of 500 voters, with 225 Republicans, 230 Democrats, and 45 independents/other party members. We will be drawing a simple random sample of 50 voters.

The probability of selecting a Republican in the sample can be calculated as the ratio of Republicans in the population to the total population size:

P(Republican) = Number of Republicans / Total population size

= 225 / 500

= 0.45

Now, we can calculate the expected value using the formula:

Expected value = Number of trials (sample size) * Probability of success (P(Republican))

Expected value = 50 * 0.45

= 22.5

Therefore, the expected value of the number of Republicans in the sample is 22.5.

If Kim has health insurance with a deductible of $500 and 80/20 coinsurance then amount she pay if she incurs a loss of $1500 is (c)$700 .

In an 80/20 coinsurance, the insurance company pays 80% of covered expenses after the deductible has been met, and the policyholder is responsible for paying the remaining 20%.

So , if Kim incurs a loss of $1500, she first needs to pay the $500 deductible before her insurance kicks in. After that, she will pay for 20% of the remaining $1000 in covered expenses:

⇒ 20% of $1,000 = $200

So, in total, Kim will pay $500 for the deductible plus $200 in coinsurance, for a total of:

Answer:

he faked too much

Step-by-step explanation:

If the stock of Company A lost $5. 31 throughout the day and ended at a value of $112. 69. The stock of Company A declined by 4.5% throughout the day.

The percentage decline in stock price is calculated by dividing the loss in value by the original value of the stock. To find out the percentage loss of stock A, we can use the formula:

(Loss in value / Original value) x 100%

Let us substitute the values we know:

Loss in value = $5.31

Original value = $118.00

Percent change = (5.31 / 118.00) x 100%

Percent change = 0.045 or 4.5%

Answer:

The answer is D) Undefined because the equation is x=-11.

If 2 angles are formed on a line, then they make a supplementary / linear pair of angles, i.e, both the angles form 180°.

Here,

Angle A = 80°

Angle B = x°

So,

Angle A + Angle B = 180°

80° + x° = 180°

x° = 180° - 80°

x° = 100°

Working with the right hand side (RHS):

Recall the half-angle identities,

sin²(x/2) = (1 - cos(x))/2

cos²(x/2) = (1 + cos(x))/2

so that

RHS = tan²(x/2)

RHS = sin²(x/2) / cos²(x/2)

RHS = (1 - cos(x)) / (1 + cos(x))

Multiply the numerator and denominator by 1 - cos(x).

RHS = (1 - cos(x)) / (1 + cos(x)) • (1 - cos(x)) / (1 - cos(x))

RHS = (1 - cos(x))² / (1 - cos²(x))

Recall that

sin²(x) + cos²(x) = 1

so that

RHS = (1 - cos(x))² / (1 - cos²(x))

RHS = (1 - cos(x))² / sin²(x)

Expanding the numerator yields

RHS = (1 - 2 cos(x) + cos²(x)) / sin²(x)

RHS = 1/sin²(x) - 2 cos(x)/sin²(x) + cos²(x)/sin²(x)

RHS = 1/sin²(x) - 2 cos(x)/sin(x) • 1/sin(x) + cos²(x)/sin²(x)

and by definition of csc and cot,

RHS = csc²(x) - 2 cot(x) csc(x) + cot²(x)

OC. $57.28

Step-by-step explanation:

It depends on how much she sells them for.

Let's say Anne sells them for $x.

Then her profit is:

8x-(8*7.16)

=8x-57.28

To make a minimum to at least make even is $57.28 and sell for $7.16 a piece.

Anne makes a profit of $57.28 on the sale of these 8 canvases. which is the correct answer would be option (C).

The profit is equal to the difference between the selling price and the original cost price.

Anne purchases art supplies for her business from a wholesaler. She spends $7.16 on eight 16 by 20-inch canvases.

To calculate the profit that Anne makes on the sale of these 8 canvases, you need to know the price at which she sells them and the cost of buying them from the wholesaler. If the cost of each canvas is $7.16 and she buys 8 of them, the total cost of the canvases is :

⇒ 8 × $7.16

Apply the multiplication operation and we get

⇒ $57.28.

Therefore, she makes a profit of $57.28 on the sale of these 8 canvases.
