b)12.042 units
c)√97
d)6√2

Answers

Answer 1

Answer:

The exact distance between two points (-2,-1) and (6,8) is = √145 units

= 12.042 units.

What is the distance between two points on a plane?

If two points on a plane is mentioned as (x₁, y₁) and (x₂, y₂), then the distance between them is √[(x₁ - x₂)² + (y₁ - y₂)²] units.

Give, two points are (-2,-1) and (6,8).

Therefore, the distance between them is

= √[(- 2 - 6)² + (- 1 - 8)²] units

= √[(- 8)² + (- 9)²] units

= √(64 + 81) units

= √145 units

= 12.042 units

Dinesh thinks that the point (1,3) is on the line y = 4x - 2.State whether Dinesh is correct and give a reason to justify your answer.
pls help me thanks

Answers

To see if the point is on the line, plug in one of the point values to see if it equals out.

y = 4x - 2 I will plug in 1 for x to see if y does = 3

y = 4(1) - 2

y = 4 - 2

y = 2 so (1, 2)

Dinesh is not correct because the point on the line when x = 1 is (1, 2) not (1, 3)

The measure,in degrees,of the three angles of a triangle are given by 2x + 1,3x - 3, and 9x.Whar is the measure of the smallest angle

Answers

(2x+1)+(3x-3)+9x = 180

14x-2 = 180

14x = 182

x = 13

Plugging back in, your angles are 27 degrees, 36 degrees, and 117 degrees, respectively. So the 2x+1 angle is the smallest.

What times itself equals 7

Answers

The answer is about 2.65. If you come up with the square root of 7 it would be around that. But, if you use the fraction trick, you would have 2 as the whole number, then having 7 subtracted by 4(because the square of two is 4) which is 3, then find the denominator which is 9(because the square of 3 is 9), so the answer is 2 1/3. So, the approximate values are 2.65 and 2 1/3.
