Whic one is further from zero -3 or -2

Bond [772]

-3 is further away from 0 because if you graph it on a number line, it will show that -3 is one unit further from 0 than -2.

I WILL GIVE YOU BRAINLY PLSS <br><br><br> Worth 19 points

Pavel [41]

Answer:

942

Step-by-step explanation :

so your d is 300 so your r = 300/2= 150

a=3.14*r*r= 3.14*150*150= 70650

c= 3.14*d= 3.14*300= 942

The curved surface area of solid cylinder is

As we are given that:

Diameter of solid cylinder = 8 cm

Length or Height o solid cylinder = 140 cm

Formula used to calculate the curved surface area of cylinder is:2n x h

Curved surface area of cylinder =2r x h

where,

r = radius of cylinder

h = height or length of cylinder

Radius of cylinder = daimeter

Now putting all the given values in above formula, we get:

Curved surface area of cylinder = 2x 22/7 x 140cm

Curved surface area of cylinder = $3520cm^{2}$

Therefore, the curved surface area of solid cylinder is3520cm^{2}

If f(x)=2(3x-5) when f(x) =74,what is the value of x??

Zinaida [17]

Answer:

x = 14

Step-by-step explanation:

given f(x) = 2(3x - 5) and f(x) = 74 , then equating gives

2(3x - 5) = 74 ( divide both sides by 2 )

3x - 5 = 37 ( add 5 to both sides )

3x = 42 ( divide both sides by 3 )

x = 14

1. Consider the population model dP dt = 0.2P 1 − P 135 , where P(t) is the population at time t. (a) For what values of P is th

Kryger [21]

Answer:

a

$P = 0$ OR $P = 135$

b

$P > 0$ and $P < 135$

OR

$P > 0$ and $P < 135$

c

Generally the carrying capacity is can be defined as the highest amount of population and environment can support for an unlimited duration or time period

d

$P = 67.5$

Step-by-step explanation:

From the question we are told that

The population model is $\frac{dP}{dt} = 0.2P(1 - \frac{P}{135} )$

Generally at equilibrium

$\frac{dP}{dt} = 0$

So

$0.2P = 0$

=> $P = 0$

Or

$(1 - \frac{P}{135} ) = 0$

=> $P = 135$

Thus at equilibrium P = 0 or P = 135

Generally when the population is increasing we have that

$\frac{dP}{dt} > 0$

So

$0.2P > 0$

=> $P > 0$

and

$(1 - \frac{P}{135} ) > 0$

$P < 135$

Now when the first value of P i.e $P< 0$ for $\frac{dP}{dt} > 0$

$P_2 > 135$

So when population increasing the values of P are

$P > 0$ and $P < 135$

OR

$P > 0$ and $P < 135$

So to obtain initial values of P where the population converge to the carrying capacity as $t \to [\infty]$

The rate equation can be represented as

$\frac{dP}{dt} = \frac{1}{5}P (1 - \frac{P}{135} )$

So we will differentiate the equation again we have that

$\frac{d^2 P}{dt^2} = \frac{(1 - \frac{P}{135} )}{5} - \frac{P}{675}$

Now as $t \to [\infty]$

$\frac{d^2 P}{dt^2} \to 0$

So

$\frac{(1 - \frac{P}{135} )}{5} - \frac{P}{675} = 0$

=> $\frac{(1 - \frac{P}{135} )}{5} = \frac{P}{675}$

=> $P = 67.5$

I need help with two questions, and an explanation on how to do them please

Lilit [14]

$39 multiply that by 1/3 OR 39 divide that by 3 . That will get 13 .

39 multiply that by 1/3 OR 39 divide that by 4 . You will get 9.75

Add 13 and 9.75

13+9.75=22.75

Now you subtract 39 - 22.75

You will get 16.25
