GarryVolchara [31]3 years ago
8 0

Answer:

Step-by-step explanation:

y = \frac{1}{5}x + 2

Find two points

When x = 0 ,  y = 0 + 2 = 2

D(0 , 2)

When x = 5;

    y=\frac{1}{5}*5+2= 1 + 2 = 3

E(5, 3)

Plot (0, 2 ) and (5 , 3) in the graph and join the points. This will be the line for the equation y =(1/5)x + 2

y = -x + 8

When x =4 ,  y = -4 + 8 = 4

A(4 , 4)

When x = 6 ;   y = -6 + 8 = 2

B(6 , 2)

Plot (4,4) and (6, 2) in the graph and join the points. This will be the line for the equation y = - x + 8.

This lines will intersect at  point (5,3) and  that point will be the solution of the equation.

Under certain conditions, the number of bacteria present in a colony is approximated by f(t) = Age 0.023t, where t is in minutes
AleksandrR [38]

Answer:

  • 5 min: 3,029,058
  • 10 min: 3,398,220
  • 60 min: 10,732,234

Step-by-step explanation:

The given function is evaluated by substituting the given values of t. This requires using the exponential function of your calculator with a base of 'e'. Many calculators have that value built in, or have an e^x function (often associated with the Ln function).

<h3>5 minutes</h3>

The number of bacteria present after 5 minutes is about ...

  f(5) = 2.7×10^6×e^(0.023×5) ≈ 3,029,058

<h3>10 minutes</h3>

The number of bacteria present after 10 minutes is about ...

  f(10) = 2.7×10^6×e^(0.023×10) ≈ 3,398,220

<h3>60 minutes</h3>

The number of bacteria present after 60 minutes is about ...

  f(60) = 2.7×10^6×e^(0.023×60) ≈ 10,732,234

It took John 12 hours riding his bike to make the round trip to his uncle's. If he averaged 20 mph out and 30 mph back, how long
notsponge [240]

Answer:

Step-by-step explanation:

Let the time taken by the john to get to his uncle be x.

Let the time taken by the john to get back from his uncle be y.

So,

x+y=12 ------ equation 1

According to the given velocities:

20x=30y

x=3/2y

Put the value x=3/2y in equation 1

3/2y+y =12

3y+2y/2=12

3y+2y=12*2

5y=24

y=24/5

y=4.8h

Now put the value of y in x=3/2y

x=3/2*4.8

x=14.4/2

x=7.2h ....

That it satisfies x = 0

Step-by-step explanation:
