Draw or Cut two  similar squares with sides b+c units long.


Draw or cut four  pairs of similar right triangles with side lengths as indicated in the diagram.

Now arrange the similar triangles at the corners of the squares such that the sides b of one similar triangle plus the side c  of a second similar triangle coincides with the length of the square.


We do another arrangement of the similar triangles. This time arrange another 4 similar triangles in the opposite corners, such that each pair forms a square.

Now comparing the two different arrangements we got two different areas that are equal.

The area of the uncovered squares in the first arrangement is a^2

The area of the two uncovered squares in the second arrangement is b^2+c^2

Equating the two areas gives the Pythagoras Theorem

a^2=b^2+c^2

Note that  a is the hypotenuse, b and c are two shorter sides of the similar right triangles.

<span>(a) At the end of Month 0, about how many more insects were in Pod A than Pod B? Explain.
In Pod A, the point is higher than 50, it could be 60 to 70 insects. Pod B has 20 insects. So, Pod A has at least 40 insects more than Pod B.

(b) Find and compare the growth rates of each pod. Show your work.
Pod A: (0,60) ; (1,80) ; (2,100) 
(80-60)/60 = 0.33
(100-80)/80 =  0.25

Pod B: (0,20) ; (1,44) ; (2,97)
(44-20)/20 = 1.2
(97-44)/44 = 1.2

Based on my computation, the rate of Pod A is lower than the rate of Pod B. 

(c) When does the population in Pod B exceed the population in Pod A? Explain. 
Pob B exceeds the population of Pod A at the END OF MONTH 4.

Pod A has a population of less than 200 while Pod B has a population of 469.</span>

Please help with this practice quiz!!

Answer:

slope is 9

Step-by-step explanation:

use the formula y=mx+b wherein m is the slope and b is the y-intercept

to solve for m, use formula (y2-y1)/(x2-x1):

\frac{127-1}{5-(-9)} = \frac{126}{14} (you add 5 and 9 together because negative + negative is positive)

126/14 = 9

The function f(x)=50⋅0.8x models the number of ants in Jonathan's ant farm after it is stricken by a deadly ant disease, where x
alina1380 [7]

Answer:

Step-by-step explanation:

In the exponential growth/decay function

y=a(b)^x, in our situation,

y is the number of ants remaining in the colony after the growth or decay,

a is the initial number of ants in the colony, and

b is the growth/decay rate.  Rule:  if b is greater than 1, the function is growth; if b is greater than 0 but less than 1, the function is decay.

Our equation looks like this (it's given):

y=50(.8)^x

a = 50, which is the initial number of ants in the colony.

b = .8 (which actually means that then number of ants is declining by 20% each week).  Since .8 is a fraction of 1, this is decay.

So far, we know that 1 and 4 are true.  Let's look at 5.  We have to do some solving to find out if it's true or not.  If the number of ants after x = 2 weeks is 32, then we plug in 2 for x and see if the y we get as the answer is 32:

y=50(.8)^2  and

y = 50(.64) so

y = 32

5 is true as well.  Let's test 6 by replacing x with 8 and seeing if y = 10:

y=50(.8)^8 and

y = 50(.16777216) so

y = 8.388

6 is not true.

1, 4, 5 are true
