What is the area of trapezoid ABCD? A(-2,2) B(2,5) C(11,-7) D(1,-2)

Ksenya-84 [330]

Answer:

50 sq. units

Step-by-step explanation:

Join one diagonal of the trapezoid ABCD.

Assume that AC is the diagonal.

So, Area of the trapezoid = Area of Δ ABC + Area of Δ CAD.

Now, coordinates of A(-2,2), B(2,5), C(11,-7) and D(1,-2) are given.

We know, that three vertices of a triangle are $(x_{1},y_{1} )$ , $(x_{2},y_{2} )$ and $(x_{3},y_{3} )$ respectively, then the area of the triangle will be given by

$\frac{1}{2} |x_{1}(y_{2}-y_{3})+x_{2}(y_{3}-y_{1})+ x_{3}(y_{1}-y_{2} ) |$

Hence, area of Δ ABC will be

$\frac{1}{2} |-2(5-(-7))+2(-7-2)+11(2-5)|= 37.5$ sq units.

Again, area of Δ CAD will be

$\frac{1}{2} |11(2-(-2))-2(-2-(-7))+1(-7-2)|= 12.5$ sq units.

Therefore, the area of the trapezoid ABCD will be (37.5 + 12.5) = 50 sq, units. (Answer)

Zarrin [17]

Based on the information given, there’ll be 8 white t-shirts in the laundry basket so we need to exclude that from the rest since we’re looking for a chance of NOT getting a white t-shirt, that’ll give us 16 out of 24 which is 66%

Identity the function that models a ball being thrown in the air with an initial velocity of 32ft/s, from a hight of 20 ft

Salsk061 [2.6K]

$\bf \qquad \textit{initial velocity}\\\\
h = -16t^2+v_ot+h_o \qquad \text{in feet}\\
h = -4.9t^2+v_ot+h_o \qquad \text{in meters}
\\ \quad \\

v_o=\textit{initial velocity of the object}\\
h_o=\textit{initial height of the object}\\
h=\textit{height of the object at "t" seconds}\\\\
-----------------------------\\\\

\begin{cases}
v_o=32\\
h_o=20
\end{cases}\implies \boxed{h(t)=-16t^2+32t+20}$
