So here we just use the Pythagorean Theorem and do: 9^2 + 6^2 = 117, then we square root that, and it gives us 10.8166538, which is the answer! Hope this helped! Brainliest is always appreciated!

Use pythagorean theorem to solve the problem. The distance of the two endpoints will be the hypotenuse. See image attached.
d² = Δx² + Δy²
d² = (x₂ - x₁)² + (y₂ - y₁)²
d² = (7 - (-2))² + (9 - 3)²
d² = (7 + 2)² + 6²
d² = 9² + 6²
d² = 81 + 36
d² = 117
d = √117
d = 10.81665..
to the nearest tenth
d = 10.8 units

The length of the segments is 10.8 units

If T={x:X is an integer between 1 and 4} (A) List down the elements of set T in set notation. B write down the number of element

GarryVolchara [31]

Answer:

The answer is given below

Step-by-step explanation:

A) Integers are whole numbers (without fraction) that are either positive or negative. If T={x:X is an integer between 1 and 4}, therefore the elements in set T = {2, 3}

B) Since the elements in set T = {2, 3}, then the number of elements in set T = 2

C) The subsets of set T are {}, {2}, {3} and {2,3}

D) Proper subset of set T are subsets of T that is not equal to T. The proper subsets of T are {2} and {3}

An improper subset of set T contains all the element of set T and a null element. The improper subset of set T are {2,3} and {}

What is the next number and why ? 1,3,11,35,99,_

Vladimir79 [104]

Answer: 241

Step-by-step explanation:

This is a simple problem when using Pascal's triangle. First you look at 1 - 3, what is the difference in these 2 numbers? Its 2, then you look at 3 and 11, the difference is 8, then 11 and 35, the difference is 24. If you keep doing this you get; 2 8 24 64 142. Next you find out how these numbers are different. In the end you keep doing this until you get to the triangles point or the differences converge.

1 3 11 35 99 241

2 8 24 64 142

6 16 40 78

10 24 38

14 14

In the end we get 14 but there is no difference in the numbers so we cant go any farther. Hope this helps!
