Which of these is another way to write the function f(x)=5x?

a. f(x)=1/4(625x)

b. f(x)=(625x)1/125

c. f(x)=(625x)1/4

d. f(x)=1/125(625x)

Answers

Answer:

d

Step-by-step explanation:

when f(x)=5......It can also be

f(x)=1/125(625x)

every whole number over one...1(625x)=625x

also 125(1)=125 therefore (625/125)x=5x

4.05 x 10^-2 Standard Form

Answers

Answer:

0.0405

Step-by-step explanation:

10^-2 is the same as 1/100, so if you multiply 4.05 x 1/100, you get 0.0405.

Another way to think about it is by looking at the exponent -2.  You need to move the decimal point 2 spaces to the left -- and add zeroes to any spaces that don't already have numbers.

So if you start with 4.05, and move the decimal one space to the left, you get 0.405, and then you move it one more space, and you get 0.0405.

What is the distance, d, between the points (3,5/2) and (5/3,1)?

Enter your answer in the box. Enter your answer in simplest radical form.

Answers

The distance between the two points is of:

[tex]D = \frac{\sqrt{145}}{6}[/tex]

------------------------------

Distance between two points:

Two points, [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]. The distance between them is given by:

[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

------------------------------

The points are [tex](3, \frac{5}{2})[/tex] and [tex](\frac{5}{3},1)[/tex].Thus, the distance between them is given by:

[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

[tex]D = \sqrt{(\frac{5}{3} - 3)^2+(1 - \frac{5}{2})^2}[/tex]

[tex]D = \sqrt{(\frac{5}{3} - \frac{9}{3})^2 + (\frac{2}{2} - \frac{5}{2})^2}[/tex]

[tex]D = \sqrt{(-\frac{4}{3})^2 + (-\frac{3}{2})^2}[/tex]

[tex]D = \sqrt{\frac{16}{9} + \frac{9}{4}}[/tex]

[tex]D = \sqrt{\frac{64 + 81}{36}}[/tex]

[tex]D = \sqrt{\frac{145}{36}}[/tex]

[tex]D = \frac{\sqrt{145}}{6}[/tex]

what is the slope???

Answers

Rise is 4 and run is 5. The line is also going left so it will be negative. The answer is -4/5

drag numbers to write an equation for the line in slope intercept form number is may be used once more than once or not at all

Answers

Answer:

y = -4x + 5

Step-by-step explanation:

The equation for the line, in slope-intercept form will take the following equation format which is y = mx + b.

Where,

b = y-intercept = 5 (this is where the line intercepts the y-axis, and also, x = 0 here)

m = [tex] \frac{y_2 - y_1}{x_2 - x_1} [/tex]

Use any two points on the line. Using (0, 5) and (1, 1), calculate m as follows:

m = [tex] \frac{1 - 5}{1 - 0} = \frac{-4}{1} = -4 [/tex]

Substitute m = -4, and b = 5 into y = mx + b.

y = -4x + 5

Step-by-step explanation:

Who is relatively taller based on their comparison to their gender, LeBron James at 81 inches or Candace Parker at 76 inches

Answers

Answer:

2. LeBron is relatively taller because he has a larger z-score.

Step-by-step explanation:

Given that ,

mean =[tex]\mu[/tex]  = 69.5

standard deviation [tex]=\sigma[/tex]  = 2.7

x = 81

Now use the formula of   z-score

[tex]z = x - \frac{\mu}{\sigma}[/tex]

z =[tex]81 - \frac{69.5}{2.7}[/tex]

z = 4.26  LeBron  

mean = [tex]\mu[/tex] = 64.2

standard deviation =[tex]\sigma[/tex]  = 3.2

x = 76

Now use the formula of   z-score

[tex]z = x - \frac{\mu}{\sigma}[/tex]

[tex]z = 76 - \frac{64.2}{3.2}[/tex]

z = 3.69 Candace  

As it can be seen that the lebron is taller as he has more z-score as compared to the Candace

If x<0 and y>0, determine the sign of the real number.​

Answers

Answer:

both negative because y is negative and make both answers negative

Answers:

6) B. Negative7) A. Positive

==============================================

Explanation:

x < 0 means x is negative

y > 0 tells us y is positive

Dividing a positive by a negative, or vice versa, means the result is negative. It's similar to how positive times negative = negative. So that is why the answer to problem 6 is "negative".

---------------

In problem 7, we square x to get some positive result.

Consider something like x = -7. Squaring this leads to

x^2 = (-7)^2 = (-7)*(-7) = 49

The two negatives cancel out when we square.

Since x^2 is positive, and y is positive, this means x^2*y is positive as well.

One inlet pipe can fill an empty pool in 6 hours, and a drain can empty the pool in 8 hours. How long will it take the pipe to fill the pool if the drain is left open? Express your answer as a reduced fraction.

Answers

Answer:

24 hours

Step-by-step explanation:

Let x represent the time required to fill both pipes if they are left open

1/6 + (-1/8)= 1/x

1/6 - 1/8= 1/x

Divide through by 48

48(1/6) -48(1/8) = 48(1/x)

8 - 6 = 48 x

2= 48/x

2x= 48

x= 48/2

x= 24

Hence it will take 24 hours to fill the pipe if the drain is left open
