What is the area of the trapezoid?<br><br> 80m2<br> 96m2<br> 100m2<br> 120 m2
never [62]

Answer:

100m^2

Step-by-step explanation:

area of trapezoid formula: ({b_{1} +b_{2})}{1/2h}

b=base

so

base #1= 8

base #2= 12

h(height)= 10

(8+12)=20(sum of bases)

20/2=10(sum of bases over 2)

10*10=100(height * whats remaining of bases)

100m^2

hope this helps

Elenna [48]
Multiply 12 by 37%.
12 × 0.37 = 4.44

B) at least 4

It could also be c... 4.44 is less than 8. But B is the closest answer to 4.44.

Evaluate the given integral by changing to polar coordinates. sin(x2 y2) dA R , where R is the region in the first quadrant betw
alexira [117]

Answer:

I = 1.47001

Step-by-step explanation:

we have the function

f(x,y)=sin(x^2y^2)\\

In polar coordinates we have

x=rcos\theta\\y=rsin\theta

and dA is given by

dA=rdrd\theta

Hence, the integral that we have to solve is

I=\int \limt_2^4 \int \limit_0^{\pi /2}sin(r^4cos^2\theta sin^2\theta)rdrd\theta

This integral can be solved in a convenient program of your choice (it is very difficult to solve in an analytical way, I use Wolfram Alpha on line)

I = 1.47001

Hope this helps!!!
