Step-by-step explanation:

you can use the rise over run technique, where you count how many units you go down or up, left or right to get to the next point. or use the slope formula :

(y2-y1)/(x2-x1)

the pairs given :

(1,6) and (3,2)

(2-6)/(3-1) = -4/2 = -2

-2 is the slope. the line is going downwards so there is a negative slope

Please help! I thought it was 90º but it says thats wrong.

Answers

Answer:

30°

Step-by-step explanation:

As the chord has same length of radius, the chord and the two radius form a equilateral triangle. Each angle of triangle is 60.So the chord subtended  at the center is 60. So the angle subtended at the remaining part of the circle = 30°

The measure of angle between the tangent and chord = 30  {Alternate segment theorem}

Answer:

Step-by-step explanation:

I posted a picture at the bottom of the post that you need to look at in order to understand this problem. I labeled everything inside that circle and then created a triangle. That triangle is made up of 3 sides that are all the same length, and that length is the length of the radius. By definition, if a triangle has all 3 of its sides the same length, it is equilateral. It is also equiangular. That means that every angle inside that triangle measures 60 degrees. The central angle, the one that comes off the center, intercepts an arc. The arc measure is the same measure as this angle, so the intercepted arc measures 60 degrees. To find the measure of the angle in question, the one you need that is labeled with a pink θ, has a rule that says the angle is going to be half the measure of the intercepted arc. That means that your angle is going to measure 30 degrees.

The length L of the base of a rectangle is 5 less than twice its height H. Write the algebraic expression to model the area of the rectangle.

Answers

Answer: 2H^2 - 5H

Explanation:
1. L = 2H - 5
2. Area of a rectangle is length (L) times height (H), so in this case, it would be (H) x (2H - 5)
3. Multiply H by everything in the parenthesis
4. You should get 2H^2 - 5H

The length L of the base of a rectangle is 5 less than twice its height H. Then the algebraic expression be, area of rectangle = 2H² - 5H.

What is the algebraic expression to model the area of the rectangle?

Let, the given information be "The length L of the base of a rectangle is 5 less than twice its height H".

L be the length of the rectangle

H be the height of the rectangle

By converting the given information into an algebraic expression, we get

Length = 2H - 5

The area of a rectangle is given by the formula;

Area of rectangle = L [tex]*[/tex] H

Where L is the Length.

H is the Height.

Substituting the values into the formula, we have;

Area of rectangle = (2H - 5) [tex]*[/tex] H

Area of rectangle = 2H² - 5H

Therefore, the area of rectangle = 2H² - 5H.

Determine if the following system of equations has no solutions, infinitely many solutions or exactly one solution. 5x + 6y = 1; - 5x - 8y = 2

Answers

Answer:

One solution

Step-by-step explanation:

Hi there!

We are given this system of equations:

5x+6y=1

-5x-8y=2

And we want to see how many solutions the equation has.

Let's solve the system in order to see how many solutions it has

Let's solve this system by elimination, where we will clear one variable by adding or subtracting the equations, solve for the other variable which wasn't cleared, and then use the value of the un-cleared variable to find the value of the variable we cleared earlier.

In order to clear a variable, the coefficients in front of those variables need to be opposites of each other (ex. if we wanted to clear y, the coefficients in front of y need to be -2 and 2 respectively). In this case, the coefficients in front of x are 5 and -5, so we can immediately add the equations

Add both equations together

-2y=3

Divide both sides by -2

y=-3/2

Now substitute -3/2 as y in either one of the equations to solve for x

If we were to do it in 5x+6y=1 for instance:

5x+6(-3/2)=1

multiply

5x-9=1

add 9 to both sides

5x=10

divide both sides by 5

x=2

So we solved the system and got x=2, y=-3/2 (or as a point, (2, -3/2)). This is the point of intersection of the two equations (in case you didn't notice, the equations are actually linear equations written in standard form). This is the ONLY point at which the lines will intersect.

Therefore, the system has one solution.

The number of music CDs sold in 1993 by one company was approximately 2.3×10^6.The number of music CDs sold by the same company in 2001 was approximately 7.9×10^7. What is the difference in CDs sold between 1993 and 2001?

The difference between  CDs sold between 1993 and 2001 will be 76.7 × 10⁵.

What is subtraction?

To subtract in mathematics is to take something away from a group or a number of objects.

In another meaning subtraction is a mathematical operation such that two values are going to subtract and give a resultant value.

The group's total number of items decreases or becomes lower when we subtract from it.

Given that sell of CDs in 1993 is 2.3 × 10⁶.

Sell of CDs in 2001 is 7.9 × 10⁷.

The difference between sell is = 7.9 × 10⁷ - 2.3 × 10⁶

76.7 × 10⁵ hence it will the correct option.

Find the size of one interior angle of a regular 10-sided polygon.

Answers

Answer:

Step-by-step explanation:

Exterior angle = [tex]\frac{360}{number \ of \ sides}[/tex]

                       [tex]=\frac{360}{10}[/tex]

                       = 36

Interior angle and exterior angles are supplementary.

interior angle + exterior angle = 180

Interior angle + 36 = 180

Interior angle = 180 - 36

Step-by-step explanation:

because we have a right triangle we apply the Pythagorean theorem

hypothenuse² = side² + side²

AB² = BC² + AC², substitute the given sides BC=8 and AC=22

AB² = 8² + 22² , square the numbers and apply the square root to both side

AB = √(64 + 484), add the numbers

AB = √548, simplify the square root

AB= 2√137 cm

Answers

Answer:

B ((2.-1), (5,3), (8, 7). (11.11 )}

Step-by-step explanation:

Linear function:

The rate of change is always the same.

Item a:

x = 2 to x = 5 -> y = 1 to y = 3. Rate of change of 2/3.

x = 5 to x = 6 -> y = 3 to y = 7. Rate of change of 4.

Different rates of change, so not linear.

Item b:

We can look that for each point, when x changes by 3, y changes by 4, so the rate of change is the same and this set of points represents a linear function, and the answer is option b.

Describe how you would determine the x-intercepts from the factored form of a quadratic equation

Answers

Answer:

Please check explanations

Step-by-step explanation:

Given the factored form, all we have to do is to equate each of the factor to zero, then solve for x

The particular value of x represents the solution that shows the value of the x-intercept

for example

In a case of a quadratic equation where we have

(x-a)(x-b) = 0

Then we can have

(x-a) = 0 or ((x-b) = 0

Then we have x = a or x = b

a and b are the x intercepts in this case
