What is the square root of 0.4 repeating?

Which statement is true about the end behavior of the graphed function?

Alik [6]

Answer with explanation:

When you will look at the graph of function, suppose it is denoted by , f(x),

represented by, y=f(x)

$\lim_{x \to \infty} f(x)=+\infty\\\\ \lim_{x \to -\infty} f(x)=+\infty$

At, x=0,the value of f(x)=0.

At, x= -∞, y= +∞

Option A: As the x-values go to positive infinity, the function’s values go to positive infinity.

is true .

A uranium mining town reported population declines of 3.2%, 5.2%, and 4.7% for the three successive five-year periods 1985–89, 1

KATRIN_1 [288]

Answer:

Step-by-step explanation:

Heres the complete question:

A uranium mining town reported population declines of 3.2%, 5.2%, and 4.7% for the three successive five-year periods 1985–89, 1990–94, and 1995–99. If the population at the end of 1999 was 9,320:

How many people lived in the town at the beginning of 1985? (Round your answer to the nearest whole number.)

solution:

Let the population of the town at the beginning of 1985 be P. Then, given that in the first five-year period the population declined by 3.2%, i.e., 0.032, the population of the town at the end of 1989 would be

(1 – 0.032)P = 0.968P.

Again, given that in the second five-year period the population declined by 5.2%, i.e., 0.052, the population of the town at the end of 1994 would be

(1 – 0.052)(0.968P) = 0.948 x 0.968P = 0.917664P.

Finally, given that in the third five-year period the population declined by 4.7%, i.e., 0.047, the population of the town at the end of 1999 would be

(1 – 0.047)(0.917664P) = 0.874533792P.

We are given, 0.874533792P = 9320 or

P = 9320/0.874533792 = 10657.11.

Thus, 10657 people lived in the town at the beginning of 1985

The total of 36, 78, 198, 475, and 620 is A. 1,187. B. 1,407. C. 2,109. D. 1,731.

Otrada [13]

The question is asking for the total of 36, 78, 198, 475 and 620. The correct option is B, that is, 1,407. Total refers to summation of a set of number, thus if the given numbers are added together, the sum total will be 1, 407. That is, 36 + 78 +198+475 + 620 =1, 407. Other words that can be used in place of total are: summation, addition or plus.

Solve A=B+C/D for C

andrew-mc [135]

Answer:

C= D(A-B)

Step-by-step explanation:

A=B+C/D

-B on both sides

A-B=C/D

*D on both sides

D(A-B)=C

Flip the equation

C= D(A-B)

A sine function has the following key features:

lakkis [162]

Answer: f(x) = 6*sin( (1/8)*π*x) + 3

Step-by-step explanation:

A sine function is written as:

f(x) = A*sin(w*x + f) + M

where:

A = amplitude

w = frequency

f = phase

M = midline

Here we know that:

Frequency = 1/8π, then: w = (1/8)*π

Amplitde = 6, then A = 6

midline = 3, then M = 3

So our equation is:

f(x) = 6*sin( (1/8)*π*x + f) + 3.

Now we also know that:

y-inercept: (0,3)

This means that:

f(0) = 3 = 6*sin( (1/8)*π*0 + f) + 3 = 6*sin(f) + 3

Now we can remember that sin(0) = 0

Then we must have f = 0.

This means that the equation is:

f(x) = 6*sin( (1/8)*π*x) + 3

So the image of the function is:
