What is the midpoint of the line segment with endpoints (3.5, 2.2) and (1.5, –4.8)?

Answers

Answer 1
Answer:

Answer:

A midpoint is a point on a line segment that divide the segment into two equal segments.

Formula for finding midpoint with any two endpoints is;

(x, y) = ((x_1+x_2)/(2) , (y_1+y_2)/(2) )

Given two end points:

(3.5 , 2.2) and (1.5 , -4.8).

Let P(x, y) be the midpoint of (3.5 , 2.2) and (1.5 , -4.8).

By midpoint formula we have;

(x, y) = ((3.5+1.5)/(2) , (2.2-4.8)/(2) )

(x, y) = ((5)/(2) , -(2.6)/(2) )

Simplify:

(x, y) = (2.5 , -1.3)

Therefore, the midpoint of the line segment with given endpoints is, (2.5, -1.3)


Answer 2
Answer: X₁ + X₂ / 2   & Y₁ + Y₂ / 2 ------------- This is the formula to plug in the coordinates.


3.5 + 1.5 / 2= 2.5      2.2 + (-4.8) / 2= -1.3

Answer = (2.5,-1.3)

Peter wants to buy a coat that costs $87 at full price.The coat is now on sale for 40% offPart A: Explain how Peter can use the fact that 10% of $87 is $8.70 to find the amount he will save on the coat


Part B: Use the same method to find the amount Peter would save on a $64 coat that is on sale for 40% off

Answers

Step-by-step explanation:

Hello!

        Part A            

Peter can use the fact that 10% of 87 is 8.70 to find the amount he would save because 40% is just 4 times bigger than 10% so he can take 8.70 from to total of the coat 4 times to find out how much it cost.

        Part B            

Using the same method we know that 10% of 64 is 6.40 so we subtract that from the price of the coat 4 times to find out how much it cost

64 - 6.40 = 57.6

57.6 - 6.40 = 51.2

51.2 - 6.40 = 44.8

44.8 - 6.40 - 38.4

The price of the coat is $38.4

Hope this helps!

Enter the degree of the polynomial below.7x7 + 10x4 + 4x3 - 5x11 - 10x6 - 6x7

A. 6
B. 7
C. 11
D. 10 ...?

Answers

I bet, you can define it by the highest degree number. So the answer is C. 11

Answer:

degree of the polynomial is 11.

C is the correct option.

Step-by-step explanation:

We have been given the polynomial

7x^7+10x^4+4x^3-5x^(11)-10x^6-6x^7

Rewrite this polynomial in standard form i.e from descending exponents

-5x^(11)-6x^7+7x^7-10x^6+10x^4+4x^3

On simplifying, we get

-5x^(11)+x^7-10x^6+10x^4+4x^3

Now, we know that the degree of the polynomial is the highest exponent.

Here, the highest exponent is 11.

Therefore, the degree of the polynomial is 11.

C is the correct option.
