The coordinates of the vertices of a quadrilateral are R(-1,3), S(3,3), T(5,-1), and U(-2,-1). Find the perimeter of the quadril

juin [17]

The distance between 2 points P(a,b) and Q(c,d) is given by the formula:

$|PQ|= \sqrt{ (a-c)^{2} + (b-d)^{2} }$

thus, the lengths of the sides of the quadrilateral can be calculated using the distance formula:

$|RS|= \sqrt{ (-1-3)^{2} + (3-3)^{2}}=\sqrt{ 16 + 0}=4$ units

$|ST|= \sqrt{ (3-5)^{2} + (3-(-1))^{2} }=\sqrt{ 4+16}=4.47$ units

$|TU|= \sqrt{ (5-(-2))^{2} + (-1-(-1))^{2} }=\sqrt{ 49 + 0}=7$ units

$|RU|= \sqrt{ (-1-(-2))^{2} + (3-(-1))^{2} }=\sqrt{ (1)^{2} + (4)^{2} }=4.12$ units

The perimeter of RSTU is 4+4.47+7+4.12=19.6

Answer: 19.6 units

Find the value of expression when b=9, c=5, d=1/2; expression is 1/2d + c^3 - b

Step2247 [10]

Answer:

115 3/4

Step-by-step explanation:

$\frac{1}{2} * \frac{1}{2}$ Because d=1/2. 1/2*1/2=1/4

C=5 so, C^3=5x5x5

C=125

Next, b=9

Then, you put everything together.

1/4+125-9=125 1/4-9

115 3/4

115 3/4+9 1/4
