PLEASE HELP!!!!!!!! 50 POINTS!!!!!!!! IVE ASKED THIS QUESTION 3 TIMES PLEASE HELP ME!!!!!!!!!!!!!

ANSWER:

[vii] By tangent property,

2y + 11 = 7y – 9
2y – 7y = – 9 – 11
– 5y = – 20
y = 4

Now, 8x – 35 = 5x – 8

8x – 5x = – 8 + 35
3x = 27
x = 9

And LO = LM

LO = 32 – (2 × 4 + 11)

LO = 32 – (8 + 11)

LO = 32 – 19

LO = LM = 13

So, Perimeter = 13 + 32 + 37 + 37 + 19

138 units.

A population of 490 bacteria is introduced into a culture and grows in number according to the equation below, where t is measur

Lera25 [3.4K]

Answer:

Rate of growth of bacteria when t=2 is 3.09 bacteria/hour

Step-by-step explanation:

As equation is not given so considering the Equation of growth of bacteria as

$P=490(1+\frac{4t}{50+t^{2}})$

We have to find the rate at which population is growing. To do so differentiate above equation w.r.to 't'

$\frac{dP}{dt}=\frac{d}{dt}490(1+\frac{4t}{50+t^{2}})\\\\\frac{dP}{dt}=490(\frac{d}{dt}(1)+\frac{d}{dt}(\frac{4t}{50+t^{2}}))\\\\\frac{dP}{dt}=490(0+\frac{4(50+t^{2})-(4t)(2t)}{(50+t^{2})^{2}})\\\\\frac{dP}{dt}=490(\frac{200+4t^{2}-8t^{2}}{(50+t^{2})^{2}})\\\\\frac{dP}{dt}=490(\frac{4(50-t^{2})}{(50+t^{2})^{2}})\\\\at\,\,t=2hours\\\\\frac{dP}{dt}=490(\frac{4(50-(2)^{2})}{(50+(2)^{2})^{2}})\\\\\\\frac{dP}{dt}=490(\frac{4(50-4)}{(50+4)^{2}})\\\\=3.09$

Rate of growth of bacteria when t=2 is 3.09 bacteria/hour

Please answer this thank you

Stells [14]

Least to greatest: -3 < -2.5 < -3/4 < -3/8 < 1/4 < 8/5 < 3.1 < 6

Greatest to least: 6 > 3.1 > 8/5 > 1/4 > -3/8 > -3/4 > -2.5 > -3

Hoped this helped! :)
