Answer:

<em>5 and 10</em>

Step-by-step explanation:  

You have all the information you need to find the area of the circle and then subtracting that from 77 you'll have the area of the rectangle and will be able to figure out the length and height by looking at the answer options.

So the area of a triangle is 1/2(b x h) or (b x h)/2 so the base is 6 and the height is 9 so the area is 54/2 which equals 27. 77 - 27 = 50 so the area of the rectangle is 50. With the answer options provided I can see that <em>the height of the rectangle is 5 and the length is 10.</em>

what is the base of the exponent in the function f(x)=3(3\8)^2x when the function is written using only rational numbers and is
NeX [460]
The answer:

by definition, an exponential function with base c is defined by <span>h (x) = ac^x</span><span> 
where a ≠0, c > 0 , b ≠1, and x is any real number.</span>
The base, c, is a constant and the exponent, x<span>, is a variable. 
</span>so if we have  f(x)=3(3\8)^2x, this equivalent to f(x)=3(3\8)^y(x),
where y (x)=2x, <span>
therefore, the base is  3/8, and the variable is the function </span>y (x)=2x,

I really don't get this type of math so can someone please help me with this thank you

The area for a trapezoid is A=1/2(b*1+b*2)h
Your base is your two parallel sides, and your parallel sides in this case is 5cm and 11cm, so that means your bases are 5&11. Your height is 4.
A=1/2(5+11)4
In order to do this you need to do the distributive property first.
1/2 x 5 = 2 1/2
1/2 x 11 = 5 1/2
Then next you need to do:
2 1/2 + 5 1/2 = 8
The last step is to do:
8 x 4 = 32
SO THE ANSWER IS 32.
