Question 1

The distance between the chords is sum of the distances between the center and the midpoint of the chords

The segments between the center to the midpoints of the chords for right triangles with one side being the radius.

The distance is:

------------------------------------------

Question 2

Midpoint of the side, the center and the vertex form a right triangle with 30° angle at the vertex.

Let the radius be r, the distance from the center to the side be h

Then we have:

As per property of 30°-60°=90° triangle, the side opposite to 30° is half of the hypotenuse. In this case, h = r/2 or r = 2h

Substitute r into equation above and solve for h:

Find the value of r:

x = - 4, x = 1

Step-by-step explanation:

The solutions to the quadratic are the values of x where the graph crosses the x- axis.

The graph crosses the x- axis at x = - 4, x = 1

Thus the solutions are x = - 4 , x = 1

Answer:

$80

Step-by-step explanation:

100/1.25 = 80

The cost price of the article that makes a profit of $100 will be $400.

The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates for one hundred percent. It is symbolized by the character '%'.

The percentage is given as,

Percentage (P) = [Final value - Initial value] / Initial value x 100

When an article is sold for $100 a profit of 25% is made on the cost price.

Let 'x' be the cost price of the article. Then the equation is given as,

25% of x = $100

Simplify the expression, then we have

0.25x = $100

x = $100 / 0.25

x = $400

The cost price of the article that makes a profit of $100 will be $400.

the equation is now 4 + 8 / 2 · 3

divide 8 and 2 = 4

4 + 4 · 3

multiply 4 and 3 = 12

4 + 12

add 4 and 12 = 16

Answer: y= 0.5x + 5.5

Step-by-step explanation: Y = mx + C

SLOPE INTERCEPT FORM:

First we need to find the slope of the two points. Which is y2-y1 / x2-x1.

8 is Y2 and 2 is Y1. 5 is Y2 and -7 is Y1. Plug those numbers into a calculator and solve. The slope (m) is 1/2 or 0.5

Then we have to find C as the slope intercept form is Y = mx + C. To find C we replace x and y with one of the points, and solve as an algebric equation. C will be 5.5

Answer:

No because the given numbers do not satisfy the equation a² + b² = c²

Answer:

No, because the given numbers satisfy the equation a^2+b^2=c^2.

Step-by-step explanation:

The Pythagorean triple 2, 3, 4. We can put it in our formula, a^2+b^2=c^2. So, that will equal:

2^2+3^2=4^2

(4+9.....16)?

And 4+9=13, which does not equal 16. So No, because the given numbers satisfy the equation a^2+b^2=c^2 is correct.

Step-by-step explanation:

The images is where I showed all the work

The solution is given below.

An equation is a  mathematical statement that is made up of two expressions connected by an equal sign.

here, we have,

One-Step Equations:

Number one: x + 6 = 8

Solve: To begin, you must subtract 6 on both sides to get x by itself.

x = 8 When you subtract 6 on both sides, you get x = 8 which is your answer.

This is a one-step equation, meaning it only took us a single step in order to solve this equation.

Number two: x - 5 = 15

Solve: To solve this one-step equation, first, start off by adding 5 on both sides.

Since it's only one step, your answer will be x = 20. All we had to do was add 5 to isolate the variable.

Two equations that contain fractions:

Number one: x - 1/2 = 2/4

Solve: x - 1/2 = 2/4

To begin, we have to add 1/2 to get x by itself. Since 2/4 and 1/2 don't have common denominators, all we have to do is multiply 1/2 by 2/2 to get a common denominator of 4. 1/2 x 2/2 is equal to 2/4. 2/4 + 2/4 is 4/4 which is equal to 1. Your answer is x = 1.

Number two: x + 3/4 = 2/4

Solve: To begin, we have to subtract 3/4 on both sides. Since 2/4 and 3/4 have a common denominator of 4, we can go ahead and subtract right away. 2/4 - 3/4 is equal to -1/4. x = -1/4.

One equation using distributive property:

Number one: 3(x + 2) = 18

Solve: To begin, we have to distribute the 3 to x and 2 (multiply). We get 3x + 6 = 18. To get x by itself, we have to first subtract 6 on both sides. We then get 3x = 12. Now, divide by 3 on both sides so that x is completely isolated, and we get x = 4.

One equation with decimals:

Number one: x + 0.25 = 0.75

Solve: To begin, we have to subtract 0.25 on both sides. When we do this, 0.75 - 0.25, we get x = .50 We can also write this as a fraction .50 is the same thing as 1/2. x = 1/2 or .50

One real-world problem:

Number one: Maria went to the store and she had 20 dollars to spend. She got a notebook for 5 dollars, and she wanted to buy pens with the rest. Each ben cost 5 dollars, how many pens can she buy in total?

Solve: We know that Maria had a total of 20 dollars in total and she already spent 5 dollars. We also know that each pen cost 5 dollars. When knowing this we can write this equation: 5x + 5 = 20. Since we don't know how many pens she's going to buy, we can just write a variable, in this case, x. Now we solve. Just like always, we need to isolate the variable. To do this, we have to first subtract 5. We then get, 5x = 15. Now, divide by 5 on both sides and we get x = 3. That means that Maria can buy a total of 3 pens.

Answer:

  s(t) = 2^(t-1)

Step-by-step explanation:

The amount in the account is the sum of the series ...

  1 + 1 +2 +4 +8 +16 +...

We note that terms after the first are a geometric sequence with a first term 1 and a common ratio 2. The sum of such a sequence is ...

  Sn = a1×(r^n -1)/(r -1) . . . . where n is the number of terms being summed

For our values, this simplifies to ...

  Sn = 1×(2^n -1)/(2 -1) = 2^n -1

We notice here that the account balance is 1 more than this sum, and that n = t-1, so the balance a(t) is ...

  s(t) = 1 +(2^(t -1) -1)

  s(t) = 2^(t -1) . . . . . . the function showing how much Jerry has
