Answer: 15(30 +33) = 945

Step-by-step explanation:

First, you have to distribute the 63 and make it smaller to become 30 + 33. So, the equation would be 15(30 + 33) = 450 + 495 = 945

A population of insects increases at the rate of 200 10t 13t2 what is the change in the population of insects between day 0 and

RUDIKE [14]

Answer:

762 days

Step-by-step explanation:

Given

$Rate = 200 + 10t + 13t^2$

Let the rate be R.

So the rate change with time is represented as:

$\frac{dR}{dt} = 200 +10t + 13t^2$

So:

$dR = (200 + 10t + 13t^2)\ dt$

To get the number of insects between day 0 and day 3, we need to integrate dR and set the bounds to 0 and 3

i.e.

$dR = (200 + 10t + 13t^2)\ dt$ becomes

$\int\limits^3_0 {dR} \, =\int\limits^3_0 (200 + 10t + 13t^2)\ dt$

$R =\int\limits^3_0 (200 + 10t + 13t^2)\ dt$

Integrate

$R = 200t + \frac{10t^2}{2} + \frac{13t^3}{3} [3,0]$

Solve for R by substituting 0 and 3 for t

$R = (200*3 + \frac{10*3^2}{2} + \frac{13*3^3}{3}) - ( 200*0 + \frac{10*0^2}{2} + \frac{13*0^3}{3})$

$R = (200*3 + \frac{10*9}{2} + \frac{13*27}{3}) - (0 + \frac{10}{2} + \frac{0}{3})$

$R = (200*3 + 5*9 + 13*9) - (0)$

$R = 600 + 45 + 117 - 0$

$R =762$

<em>The population of insect between the required interval is 762</em>

What is the total number of outcomes if you there are three sizes of milk shakes (S,M.L) and five flavors of ice cream (Vanilla,

Elis [28]

5 small milkshake outcomes

5 medium milkshake outcomes

and

5 large milkshake outcomes

since there are only 5 flavors you can only make 5 different milkshakes unless you want to mix the flavors to make

5+10= 15 so you could make 15 that mixing each ice cream with each other and then mixing all of them.

ss7ja [257]

Answer:

y=-7x-22

Step-by-step explanation:

y-y1=m(x-x1)

y-6=-7(x-(-4))

y-6=-7(x+4)

y=-7x-28+6

y=-7x-22
