What is exponential function?

The exponential function is a mathematical function denoted by f(x)=\exp or e^{x}. Unless otherwise specified, the term generally refers to the positive-valued function of a real variable, although it can be extended to the complex numbers or generalized to other mathematical objects like matrices or Lie algebras.

here, we have,

given that,

the approximate population P of a bacteria colony is given by

P = 15t ^ (5/3)

where t is the number of days start of the experiment .

now,

the population of the colony on the 8th day is,

15×8^(5/3)

= 15×∛8^5 ]

= 15×2^5

= 15×32

= 480

hence, Population after 8 days is 480.

Write the complete factorization of 22xy^2

Answers

Answer:

2 * 11 * x * y * y

Step-by-step explanation:

The numerical part is 22, whose prime factor form is: 2 * 11

Then the complete factorization of 22 x y^2 is:

2 * 11 * x * y * y

The complete factorization of [tex]22xy^2[/tex] is [tex]2 \times 11 \timesx \times y \times y[/tex]

Given that,

The equation is [tex]22xy^2[/tex]

Based on the above information, the calculation is as follows:

Here the numerical part should be 22 whose prime factor should be 2 and 11.

Now  the complete factor should be [tex]2 \times 11 \timesx \times y \times y[/tex]

Answers

Answer:

B. 3.6

Step-by-step explanation:

I have no idea if this is right but my logic is 3.6 - 3.6 = 0

Answer:

B. 3.6

Step-by-step explanation:

The equation is

w - 3.6 = 0

That means start with some number. Then subtract 3.6 from that number. The result is 0. What number is it that when you subtract 3.6 from it you get 0? That number is 3.6 since 3.6 - 3.6 = 0. That means w, the unknown, must equal 3.6.

That is the explanation.

The way to solve the equation is to see what is being done to the unknown. The unknown here is w. On the left side, you see 3.6 being subtracted from w. In order to undo a subtraction, you must do the opposite operation which is an addition. In order to undo a subtraction of 3.6, you must add 3.6. The rule with equations is that you must do the same operation to both sides of the equation, so add 3.6 to both sides of the equation.

w - 3.6 = 0

Add 3.6 to both sides.

w - 3.6 + 3.6 = 0 + 3.6

w = 3.6

Answer: B. 3.6

In the email data set in Chapter 1, the number variable de- scribed whether no number (labeled none), only one or more small numbers (small), or whether at least one big number appeared in an email (big). Of the 3,921 emails, 549 had no numbers, 2,827 had only one or more small numbers, and 545 had at least one big number. (a) Are the outcomes none, small, and big disjoint

Answers

Answer:

These outcomes are disjoint.

Step-by-step explanation:

(a) Are the outcomes none, small, and big disjoint

If they are disjoint, the sum of the total number of each has to be equals to the number of emails.

We have:

3921 emails.

549 with no numbers.

2827 with only one or more small numbers

545 had at least one big number.

549 + 2827 + 545 = 3921

Since the sum is equals to the number of emails, these outcomes are disjoint.

10. A rectangle has a perimeter of 22 cm. If the length of the rectangle is 2 cm more than two times the
width, what are its dimensions?

Answers

Answer:

w = 3 cm

l = 8 cm

Step-by-step explanation:

let 'w' = width

let '2 + 2w' = length

P = 2l + 2w

22 = 2(2 + 2w) + 2w

22 = 4 + 4w + 2w

22 = 4 = 6w

18 = 6w

w = 3

length = 2 + 2(3) = 18

At a football stadium, 4% of the fans in attendance were teenagers. If there were 260 teenagers at the football stadium, what was the total number of people at the stadium?

Answers

Answer:

solution

4%=260

100%=?

=(100x260)/4

=6500

Percentage of fans in the stadium who were teenagers = 4%

Number of teenagers in the match = 260

Let the total number of people at the stadium be x.

Which means :

[tex] =\tt 4\% \: \: of \: \: x = 260[/tex]

[tex] =\tt \frac{4}{100} \times x = 260[/tex]

[tex] =\tt \frac{4 \times x}{100} = 260 [/tex]

[tex] = \tt \frac{4x}{100} = 260[/tex]

[tex] = \tt4x = 260 \times 100 \\ \tt \: \: \: = 26000[/tex]

[tex] =\tt x = \frac{26000}{4} [/tex]

[tex]\color{plum} =\tt x = 6500[/tex]

▪︎Therefore, number of people at the stadium = 6500

The number of measles cases decreases by 9 percent to 508 cases. What was the number of cases before the decrease

Answers

Answer:

558

Step-by-step explanation:

The original number of cases of measles was x.

x was 100% of the number of cases of measles.

The number of cases then went down by 9%.

100% - 9% = 91%

The number of cases now is 91% of the original number, or 91% of x. We are told the number now is 508, so 91% of x must equal 508.

91% of x = 508

0.91x = 508

x = 508/0.91

x = 558.241...

Answer: 558
