Jet001 [13]

Answer:

157286400 bacteria

Step-by-step explanation:

We are given the following in the question:

The bacteria increases 4 times every 6 hours.

Initially there are 150 bacteria.

Thus, we can write the function for number of bacteria after x hours,

$f(x) = 150(4)^{\frac{x}{6}}$

We have to find the number of bacteria in 2.5 days.

1 day = 24 hours

Thus,

$2.5\text{ days} = 24\times 2.5 = 60\text{ hours}$

Putting x = 60 in the above equation, we get,

$f(60) = 150(4)^{\frac{60}{6}} = 150(4)^{10} = 157286400$

Thus, there will be 157286400 bacteria in two and a half days.

Ostrovityanka [42]

Answer:

dC/dt = 2 mg*cm³/s

Step-by-step explanation:

Given

C(t)= (1/2)*(4t+ 4)- (1/2)

we apply dC/dt as follows

dC/dt = d((1/2)*(4t+ 4)- (1/2))/dt = (1/2)*(4) = 2

⇒ dC/dt = 2 mg*cm³/s

URGENT!!!Find the value of x.

Debora [2.8K]

a x=12

the sum of angles in a triangle is 180

53+39+4+7x=180

96+7x=180

7x=86

x=84/7

x=12

b. sum of angles in a triangle is 180

5x+(6x-5)+75=180

5x+6x-5+75=180

11x+70=180

11x=180-70

11x=110

x=110/11

x=10

that's how to solve it
