Answer: Let's solve your equation step-by-step.

2h−3=3

Step 1: Add 3 to both sides.

2h−3+3=3+3

2h=6

Step 2: Divide both sides by 2.

2h/2 = 6/2

h = 3.

Given:

The growth of a sample of bacteria can be modeled by the function

[tex]b(t)=100(1.06)^t[/tex]

where, b is the number of bacteria and t is time in hours.

To find:

The number of total bacteria after 3 hours.

Solution:

We have,

[tex]b(t)=100(1.06)^t[/tex]

Here, b(t) number of total bacteria after t hours.

Substitute t=3 in the given function, to find the number of total bacteria after 3 hours.

[tex]b(t)=100(1.06)^3[/tex]

[tex]b(t)=100(1.191016)[/tex]

[tex]b(t)=119.1016 [/tex]

Therefore, the number of total bacteria after 3 hours is 119.1016.

Answer:

d-2x-3

Step-by-step explanation:

The factor of the trinomial will be (2x + 3) and (2x + 3). Then the correct option is D.

It is a method for dividing a polynomial into pieces that will be multiplied together. At this moment, the polynomial's value will be zero.

The trinomial is given below.

⇒ 4x² + 12x + 9

Then the factor of the trinomial will be

⇒ 4x² + 12x + 9

⇒ 4x² + 6x + 6x + 9

⇒ 2x(2x + 3) + 3(2x + 3)

⇒ (2x + 3)(2x + 3)

⇒ (2x + 3)²

Then the correct option is D.

Answer:

a. 1/5

b. (3, 3/5)

c. 1/5x = y

Step-by-step explanation:

Remember: (x, y)

0.5 = 1/2

(1/2, 1/10) = 1/10 ÷ 1/2 = 1/10 • 2 = 1/5, you can divide y/x = constant of proportionality. 1/10 ÷ 1/2.

1 2/5 = 7/5

(7, 7/5) = 7/5 ÷ 7 = 7/5 • 1/7 = 1/5, y/x = constant of proportionality. 7/5 ÷ 7.

Answer:

The first car reaches its destination in 6 hours.

Step-by-step explanation:

Speed of the first car = 50 miles per hour

Time taken = t hours

Distance travelled = Speed × Time = 50 t

Speed of the second car = 60 miles per hour

Time taken = [tex](t-1)[/tex] hours

Distance travelled = Speed × Time = [tex]60(t-1)[/tex]

As two cars travel the same distance,

[tex]50t=60(t-1)\\50t=60t-60\\60=60t-50t\\60=10t\\t=\frac{60}{10}\\t=6[/tex]

So, the first car reaches its destination in 6 hours.

It would take the first car 6 hours to reach its destination.

Speed is the ratio of distance to time. It is given by:

Speed = distance /time

Since the two cars travel at the same distance, let d represent this distance.

The first car travel at 50 miles per hour and reaches its destination at t hours. Hence:

50 = d / t

d = 50t   (1)

The second car travels at a rate of 60 miles per hour and reaches its destination 1 hour earlier than the first car. Hence the time = t - 1. Hence:

60 = d / (t - 1)

d = 60(t - 1)

d = 60t - 60   (2)

Equating both equations gives:

50t = 60t - 60

10t = 60

t = 6 hours

Hence it would take the first car 6 hours to reach its destination
