What is the area of ABC? I need to find out how many units, please help

nikitadnepr [17]

To find the area of this figure, let's first split this into two triangles by drawing a vertical line from point B down to the bottom of the figure. We then have two triangles:

One triangle with a base of 6 units and a height of 6 units
And a second triangle with a base of 1 unit and a height of 6 units

We know that to find the area of a triangle, we must use the equation:

$A= \frac{1}{2}bh$

So let's solve for the first triangle:

$A= \frac{1}{2}(6)(6)=18 units^{2}$

The let's solve for the second triangle:

$A= \frac{1}{2}(1)(6)=3 units^{2}$

Now to find the total area of the figure, let's add them together:

$18units^{2}+ 3units^{2} = 21units^{2}$

Now we know that the area of this figure is $21 units^{2}$ .

Please answer my question

GarryVolchara [31]

Answer:

$\frac{8}{3}$

Step-by-step explanation:

mean: (22+12+14+14+13+9)=14

|22-14| + |12-14| + ... + |9-14| =16

MAD = 16/6 = $\frac{8}{3}$

If f(x)=2x and g(x)=−2x3+2x, then what is f(x)+g(x)?

Maurinko [17]

Answer:

$-2x^3+4x$

Step-by-step explanation:

I am assuming that the functions are:

$f(x)=2x\\\\g(x)=-2x^3+2x$

-----------------------

$f(x)+g(x)\\\\2x+-2x^3+2x\\\\2x+2x+-2x^3\\\\4x+-2x^3\\\\\boxed{-2x^3+4x}$

Hope this helps you!

A 6,000-liter cistern is empty when water begins flowing into it (at t = 0) at a rate (in L/min) given by Q`(t) = 9 √t, wher

lorasvet [3.4K]

Answer:

a) 6,455 L

b) V(t) = (18/3) * t^(1.5)

Step-by-step explanation:

Part a

Integrating the given relation from t = 0 to t= 105 mins

$V = \int {9 * \sqrt{t} } \, dt\\V = {\frac{9*2}{3}*t^(1.5) = \frac{18}{3}*t^(1.5)\\\\V = \frac{18}{3}*105^(1.5)\\\\\\V = 6,455L$

Part b

$V(t) = \frac{18}{3} * t^(1.5) + C\\Since V = 0 @ t = 0 ; hence, C = 0\\\\V(t) = \frac{18}{3} * t^(1.5)$
