Find the distance between each pair of points. (-8, -2) and (6,-1) d=/(x2 – x,)? +(y2 – y,)?

Answers

Answer 1

Answer:

Answer:

d ≈ 14 units

Step-by-step explanation:

calculate the distance d using the distance formula

d = $\sqrt{(x_(2)-x_(1))^2+(y_(2)-y_(1))^2 }$

let (x₁, y₁ ) = (- 8, - 2 ) and (x₂, y₂ ) = (6, - 1 )

substitute these values into the formula for d

d = $√((6-(-8))^2+(-1-(-2))^2)$

= $√((6+8)^2+(-1+2)^2)$

= $√(14^2+1^2)$

= $√(196+1)$

= $√(197)$

≈ 14 units ( to the nearest whole number )

1.75 = 12.3 - x / 2.8

Solve for x

Answers

1.75=12.3-x/2.8
x=(12.3-1.75)2.8
x=29.54

1.75 = 12.3 - x / 2.81.75-12.3=-x/2.8

-10.55=-x/2.8

-10,55*-2.8=x

x=29.54

The measure of W is 134°, the measure of Y is 46°, and the measure of Z is 134°.What is the measure of X?
a 40°
b 46°
c 134°
d 90°

Answers

The angles in any quadrilateral must add up to 360 degrees.
A trapezoid is a quadrilateral, because it has four sides.

$W+X+Y+Z=360 \n \n (134)+X+(46)+(134)=360 \n \n 314+X=360 \n \n X=46$

Angle X is (b) 46 degrees.

B. 46 because the measure of all of the angles in a quadrilateral is 360. If you add 134+46+134 it equals 314, and 360-314 is 46.

Answers

Answer:

increase 15% = 1+(15/100)=1.15

increase 1.8% =1+(1.8/100)=1.018

evolution coefficient: 1.15*1.018=1.1707

overall percentage increase
