Answer:

32  units^2

Step-by-step explanation:

To find the area of this irregular shape, you can split it into 3 triangles, and 1 square.

The formula for finding the area of a triangle is:

A = \frac{1}{2} bh

The formula for finding the area of a square is:

A = lw

<em><u>Finding area of large triangle:</u></em>

<em><u /></em>A = \frac{1}{2} (4)(10)\\\A = 20

<em><u>Finding area of bottom left triangle:</u></em>

<em><u /></em>A = \frac{1}{2} (2)(2)\\A=2

<em><u>Finding area of last triangle (bottom right):</u></em>

<em><u /></em>A = \frac{1}{2} (2)(6)\\A=6

<em><u>Finding area of square:</u></em>

<em><u /></em>A = (2)(2)\\A = 4

Answer:

32

Step-by-step explanation:

Area of a big right triangle = 1/2 * 4 * (2+2+6) = 1/2 * 4 *10 =20

Area of a left right triangle = 1/2* 2*2 = 2

Area of a right right triangle = 1/2 * 6*2 =6

Area of a square = 2*2 = 4

All together:

20+ 2+6+4 =32

Compound interest of $1000 is invested at 10% compounded continuously, the future value s at any time t in years is given by s=1
crimeas [40]

Answer: 6.93 years

Step-by-step explanation:

Given

Rate of interest is r=10\%

Future value is given by s=1000e^{0.1t}

For the investment to double itself, i.e. s=2000

\Rightarrow 2000=1000e^{0.1t}\\\Rightarrow 2=e^{0.1t}\\\\\text{Taking log both sides}\\\\\Rightarrow \ln 2=0.1t\\\\\Rightarrow t=\dfrac{\ln 2}{0.1}\\\\\Rightarrow t=6.93\ \text{years}

It takes around 6.93 years to double the investment.

Solve for the roots in simplest form using the quadratic formula:<br> 4x2 + 4x = -5
weqwewe [10]

Answer:

Step-by-step explanation:

Move all terms to one side

4x^2 + 4x + 5 = 0

Plug into quadratic formula

x = (-4 <u>+</u> \sqrt{16 - 4(4)(5)}) / 2(4)

  = (-4 <u>+</u> \sqrt{-64})/8

At this point, there are no real answers. The roots to this equation are complex.

x = (-4 <u>+</u> 8i)/8

  = (-1 <u>+</u> 2i)/2
