I need some help with this problem​

Distance = 13 units

Point A: (8, -7)

Point B: (-4, -2)

[tex]\sqrt{(8 + 4)^{2} + (-7 + 2)^{2} }[/tex]

[tex]\sqrt{(12)^{2} + (-5)^{2} }[/tex]

[tex]\sqrt{144 + 25 }[/tex]

[tex]\sqrt{169}[/tex]

[tex]13[/tex]

Answer:

[tex]\boxed {d = 13}[/tex]

Step-by-step explanation:

Use the Distance Formula to help you find the distance between the two following points:

[tex]d = \sqrt{(x_{2} - x_{1})^{2} + (y_{2} - y_{1})^{2}}[/tex]

(where [tex](x_{1}, y_{1})[/tex] represents the first point and [tex](x_{2}, y_{2})[/tex] represents the second point)

-Apply the two following onto the formula:

[tex](x_{1}, y_{1}) = (8, -7)[/tex]

[tex](x_{2}, y_{2}) = (-4, -2)[/tex]

[tex]d = \sqrt{(-4 - 8)^{2} + (-2 + 7)^{2}}[/tex]

-Solve for the distance:

[tex]d = \sqrt{(-4 - 8)^{2} + (-2 + 7)^{2}}[/tex]

[tex]d = \sqrt{(-12)^{2} + 5^{2}}[/tex]

[tex]d = \sqrt{144 + 25}[/tex]

[tex]d = \sqrt{169}[/tex]

[tex]\boxed {d = 13}[/tex]

Therefore, the distance is [tex]13[/tex].

Answer:

The most quickly reveals the vertex is g(x) = -2(x + 4)² + 18 ⇒ b

The vertex = (-4, 18)

Step-by-step explanation:

The vertex form of the quadratic function f(x) is:

f(x) = a(x - h)² + k, where

The most quickly reveals to find the vertex is the vertex form above

Look at the answer and try to find a similar form to the vertex form above

∵ g(x) = -2(x + 4)² + 18

∴ a = -2

∴ h = -4

∴ k = 18

⇒ That means this form is similar to the form above

∴ The most quickly reveals the vertex is g(x) = -2(x + 4)² + 18

∴ The vertex = (-4, 18)

Answer:

302.4

Step-by-step explanation:

252% × 120 =

(252 ÷ 100) × 120 =

(252 × 120) ÷ 100 =

30,240 ÷ 100 =

302.4

Answer: 302.4

Step-by-step explanation:

Write 252% as  

252/100

Since, finding the fraction of a number is same as multiplying the fraction with the number, we have

252/100 of 120 = 252/100 x 120 =

Therefore, the answer is 302.4

Answer:

Angle AOB and angle DOC are identical because they share 2 parallels considering it is a bisection

Step-by-step explanation:

Answer: a= x+14 /b+3

Step-by-step explanation:

Answer:

Step-by-step explanation:

Simplifying

14 + x = 3a + ab

Solving

14 + x = 3a + ab

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-14' to each side of the equation.

14 + -14 + x = 3a + -14 + ab

Combine like terms: 14 + -14 = 0

0 + x = 3a + -14 + ab

x = 3a + -14 + ab

Reorder the terms:

x = -14 + 3a + ab

Simplifying

x = -14 + 3a + ab

Answer:

[tex]40x+25y=19,000[/tex]

Step-by-step explanation:

[tex]x[/tex] denotes the number of adult admission tickets sold and [tex]y[/tex] denotes the number of child admission tickets sold.

Cost of an adult admission ticket = $40

Cost of [tex]x[/tex] adult admission tickets = $40[tex]x[/tex]

Cost of a child admission ticket = $25

Cost of [tex]y[/tex] child admission tickets = $25[tex]y[/tex]

Total amount paid by 625 people = $19,000

So,

[tex]40x+25y=19,000[/tex]

Hope This Helps!

Plz Mark Brainlies!

Answer:

D is for sure a function and just so you know A is never a function.

Step-by-step explanation:

Answer:

I think it would be -2 or h(x)=-2

Step-by-step explanation:

because if x=3 then that would be 5 x 3 and that would be 15 so 15-17=-2

hope this helps if not sorry!! :)

Step-by-step explanation:

41.25 because you divide the cost into the profit and that equals 41.25

Answer:

$41.25

Step-by-step explanation:

recall that the formula for percent markup is

% Markup = [ (price - cost) / cost ]     x     100%   (also see attached for reference)

we are given:

% Markup = 65%

Cost = $25

Simply substitute the known values into the formula above

% Markup = [ (price - cost) / cost ]       x     100%

65 = [ (price - 25) / 25]     x 100

65/100 = (price - 25) / 25

0.65 = (price - 25 ) / 25

0.65 (25) = price - 25

price - 25 = 16.25

price = 25 + 16.25

price = $41.25

Answer:

A. 14,406. it runs by a -7 sequence, so D would be the 6th in the sequence.

Step-by-step explanation:

Incomplete question. Here's the full question:

At the beginning of the day, the stock market goes up 30 1/2 points. At the end of the day, the stock market goes down 120 1/4 points. What is the total change in the stock market from the beginning of the day to the end of the day?

Answer:

-15%

Step-by-step explanation:

First, we convert the fraction to a whole number;

At the beginning of the day: [tex]30\frac{1}{2}[/tex] = 15 (30*1 / 2)

At the end of the day:  [tex]120\frac{1}{4}[/tex] = 30 (120 * 1 / 4)

Next, since we are told that at the end of the day, the stock market goes down, it means we will subtract any gain it had by the change;

[tex]15-30 = -15%[/tex]%

Hence, the total change in the stock market from the beginning of the day to the end of the​ day is -15%.

Answer:

D. -3 and 3

Step-by-step explanation:

We are given an output of 2. This means this is the value we need an input for. We need to find a number(s) that lie on the x axis and when we move up, you get an output of 2.

Option A:

If we are given an input of -2, we start at (-2, 0) and move up until we reach a point on the line. We end up lying on the point (-2, 3). Thus, the output for having an input of -2 is 3 which proves that this answer is incorrect.

Option B:

As stated above -2 has an output of 3 which is wrong. Since we know this, we can eliminate this as an option.

Option C:

If we are given an input of -3, we start at (-3, 0) and move up until we reach a point on the line. We end up lying on the point (-3, 2). Thus, the output for having an input of -2 is 2 which proves that this answer is correct.

Option D:

We know that -3 is a possible input so we just need to check 3 as an input.

If we are given an input of 3, we start at (3, 0) and move up until we reach a point on the line. We end up lying on the point (3, 2). Thus, the output for having an input of 3 is 2 which proves that this answer is also correct.

Since we know that -3 and 3 are possible inputs for an output of 2 on the graph, we need to include them both in our answer. Thus, the answer is D.

Best of Luck!

y= 3/4z + 25/4

Step-by-step explanation:

Answer:

18 sides

Step-by-step explanation:

Exterior angle = 360° ÷ n

20° = 360°/n

n× 20 = 360/n ×n

20n = 360

n= 360/20

n = 18
