If your looking looking for the y-intercept its y=-3

I don't really understand what you are asking though....

You want to get the x to the right side of the equal sign, so to do so you have to flip the sign,which gets you

Y=-x-3

So you would start at negative three(on the graph) and then go down 1, over to the right one.

What is the area of this figure?

insens350 [35]

Answer:

54 units squared

Step-by-step explanation:

You have to divide the shape into simpler shapes such as rectangles and triangles that you can easily find the area of. Then, add those areas together. I divided it into one rectangle and three triangles.

Rectangle 1: length=7 width=6 6(7)=42

Triangle 1: base=6 height=2 1/2(6)2=6

Triangle 2: base=3 height=2 1/2(3)2=3

Triangle 3: base=6 height=1 1/2(6)1=3

Area= R1+T1+T2+T3= 42+6+3+3= 54 units squared

trasher [3.6K]

Answer:

The answer is "26179.4".

Step-by-step explanation:

Assume year 2000 as t, that is t =0.

Formula:

$A= A_0e^{rt}$

Where,

$A_0 = \ initial \ pop \\\\r= \ rate \ in \ decimal \\\\t= \ time \ in \ year$

for doubling time,

$r = \frac{log (2)}{t} \\$

$r = \frac{\log (2)}{ 40} \\\\r= \frac{0.301}{40}\\\\r= 0.007$

Given value:

$A = A_0e^{rt} \\\\$

$A_0 = 13000$

$t= 40 \ years$

when year is 2000, t=0 so, year is 2100 year as t = 100.

$A = 13000 \times e^{et}\\\\A = 13000 \times e^{e \times t}\\\\A = 13000 \times e^{0.007 \times 100}\\\\A = 13000 \times e^{0.7}\\\\A= 13000\times 2.0138\\\\A = 26179.4$
