To find the area of a trapezoid, we use the following formula:
a = \frac{1}{2} (b1 + b2) \times h
In this formula a represents the area and b1 and b2 each represent a base of the trapezoid.

So, we have got the following information
a = 150
b1 = 14
b2 = 16

Filling in the formula gives us:
150 = \frac{{1} }{2} \times (14 + 16) \times h
150 = \frac{1}{2} \times 30 \times h
150 = 15 \times h
Finally we have to divide both sides by 15.
h = 150 \div 15 = 10
Therefore, the height of the trapezoid is 10 meters.

The answer is about 27oz. and this is how you answer it.
<span>pi(d/2)^2 * h = V
3.14(3.6in./2)^2 * 5.9in. =
3.14(1.8in.)^2 * 5.9in.   =
3.14 * 3.24 * 5.9in. ~
10.17in. * 5.9in. ~ 60in.^2
and 1in.^2 = 0.45oz. so
60 * 0.45oz. = 27oz.
that is with rounding to the nearest hundredth.

What is the value of k in the equation?<br> 20^k/ 20^4 = 20^9
Luden [163]

Answer:

k = 13

Step-by-step explanation:

20 ^ k / 20^4 = 20^9

knowing the laws of exponents, diving two numbers of the same base with exponents is like subtracting the exponents, so

k^x / k^y

= k ^ (x - y)

apply that knowledge here

20 ^ k / 20 ^ 4 = 20 ^ 9

20 ^ ( k - 4 ) = 20 ^ 9

now the bases have no use here so ignore them, and just calculate the exponents

k - 4 = 9

solve using inverse operations

k - 4 = 9

+4       +4

k = 13

V=x(8-2x)(10-2x) or expanded

V=x(4x^2-36x+80)

V=4x^3-36x^2+80x

...

If you were to graph the above equation for V(x) you will see a maximum point where the "y" value is maximized, but be careful as V will increase without bound at values of x that are not part of the domain, ie, in this case x<8/2, x<4 to have any meaning...The proper domain of this function is:

x=(0,4), Mathematically finding this point quickly is by differentiating it with respect to x...

dV/dx=12x^2-72x+80, The maximum volume will occur when dV/dx=0 and the x value is within the correct domain...

12x^2-72x+80=0  (using the quadratic formula for ease)

x=(72±√1344)/24, and since x<4

x≈1.472in  (to the nearest one thousandth of an inch)
