Answer:

x = 0.4

Step-by-step explanation:

Hello, great question. These types are questions are the beginning steps for learning more advanced Algebraic Equations.

Assuming that (2x2) means 2 being multiplied by 2. Then we can use the following process to solve the equation given to us in the question.

$2*2-5x+1 = 3$ .... First, multiply both 2's together

$4-5x+1 = 3$ ....combine 4 and 1

$5-5x = 3$ ....subtract 5 on both sides

$-5x= -2$ ... divide both sides by -5

$x = 0.4$

After following the process and solving for x we can see that the value of x is 0.4

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.

During the exponential phase, E. coli bacteria in a culture increase in number at a rate proportional to the current population.

NikAS [45]

Answer:

197.2 million

Step-by-step explanation:

The appropriate exponential equation for the population is ...

p(t) = 172.0e^(0.019t)

Then we can compute for t=7.2:

p(7.2) = 172.0e^(0.019·7.2) ≈ 172.0·1.146599 ≈ 197.2

7.2 minutes from now, the population will be about 197.2 million.

___

For continuous growth (or continuous compounding), the exponential formula is ...

f(t) = (value at t=0)×e^(rt)

where r is the growth rate in one unit of time, and t is the number of time periods.

Answer:

Option A. one rectangle and two triangles

Option E. one triangle and one trapezoid

Step-by-step explanation:

step 1

we know that

The area of the polygon can be decomposed into one rectangle and two triangles

see the attached figure N 1

therefore

Te area of the composite figure is equal to the area of one rectangle plus the area of two triangles

$A=(8)(4)+2[\frac{1}{2}((8)(4)]=32+32=64\ yd^2$

step 2

we know that

The area of the polygon can be decomposed into one triangle and one trapezoid

see the attached figure N 2

therefore

Te area of the composite figure is equal to the area of one triangle plus the area of one trapezoid

$A=\frac{1}{2}(8)(4)+\frac{1}{2}((4+8)(8)=16+48=64\ yd^2$

Which Venn diagram correctly describes the relationship between the set of integers and the set of whole numbers

Brums [2.3K]

Answer:

Option (A).

Step-by-step explanation:

Option (A).

All whole numbers are integers.

True.

Option (B).

Whole numbers and integers have no element in common.

False. All whole numbers are integers. Therefore, whole numbers are contained in integers on Venn diagram.

Option (C).

All integers are whole numbers.

False. All whole numbers are integers.

Option (D).

Some whole numbers are integers.

False. All whole numbers are integers.
