Answer:

AB+AC

Step-by-step explanation:

Given: \frac{BX}{XC}=\frac{AB}{AC}

To determine: (BX+XC) : XC =? : AC

We need to find ? here

We have

\frac{BX}{XC}=\frac{AB}{AC}

Add 1 both sides

\frac{BX}{XC}+1=\frac{AB}{AC}+1

Taking LCM and simplify it

\frac{BX+XC}{XC}=\frac{AB+AC}{AC}

We can write fraction as ration

(BX+XC) : XC= (AB+AC) : AC

At place of "?" we get AB+AC

Thus, option 3 is correct. AB+AC

A certain population of bacteria has an initial population of 225. the bacteria triples every hour. determine the multiplier tha
dimaraw [331]

Using an exponential function, it is found that the multiplier that would allow you to predict the population of bacteria after 2 hours is of 9.

<h3>What is an exponential function?</h3>

An exponential function is modeled by:

y = ab^x

In which:

  • a is the initial value.
  • b is the growth rate.

In this problem, the bacteria triples every hour, hence the rate of change is b = 3, and the equation is:

y = a(3)^x

Hence, after 2 hours:

y = a(3)^2 = 9a

Which means that the multiplier is of 9.

3. The sum of three consecutive integers is 1,623.
TiliK225 [7]

Answer:

540, 541, 542

Step-by-step explanation:

let the number be n

hence the 3 consecutive numbers may be expressed as:

n , n+1, n+2

it is given that the sum of the 3 numbers is 1623

hence,

n + (n+1) + (n+2) = 1623

n + n + 1 + n + 2 = 1623

3n + 3 = 1623

3n = 1623 -3

3n = 1620

n = 1620 / 3

n = 540

hence the numbers are

540, (540 + 1) , (540 + 2)

or

540, 541, 542
