Given rectangle ABCD with vertices A(1, 4), B(3, 6), C(6, 3), and D(4, 1), what is the
Hitman42 [59]

Answer:

  10√2

Step-by-step explanation:

A(1, 4), B(3, 6), C(6, 3), D(4, 1)

The distance formula tells you the distance d between two points (x1, y1) and (x2, y2) is given by ...

  d = √((x2-x1)² +(y2-y1)²

Then the side lengths are ...

  AB = √(2² +2²) = √8 = 2√2

  BC = √(3² +(-3)²) = √18 = 3√2

The perimeter is twice the sum of these sides, so is ...

  P = 2(2√2 +3√2) = 10√2 . . . the perimeter of the rectangle

In ΔSTU, u = 23 inches, ∠T=158° and ∠U=17°. Find the length of t, to the nearest 10th of an inch.
Evgesh-ka [11]

Answer: t = 29.5 inches

Step-by-step explanation:

Given that the ΔSTU, u = 23 inches, ∠T=158° and ∠U=17°. 

We can Find the length of t by using sine rule

t/saint = u/sinU

t/sin158 = 23/sin17

t = sin158 × 23/sin17

t = 29.47 inches

t = 29.5 inches

Write the equation of the line, in slope intercept form, through the following points:
lakkis [162]

Hey!

------------------------------------------------

First, find the slope.

y2-y1/x2-x1

-20-(-5)/21-16

-15/5

-3

------------------------------------------------

Second, find the y-intercept.

We can solve for b with one of the points.

Put into slope-intercept form,

y = -3x + b

Substitute x and y with (16, -5)

-5 = -3(16) + b

-5 = -48 + b

-5 + 48 = -48 + b + 48

43 = b

------------------------------------------------

Third, put in slope-intercept form.

y = mx + b

m = slope

b = y-intercept

y = -3x + 43

------------------------------------------------

Hope This Helped! Good Luck!
