Scientific notation of 5,000,039 is = 5.000039 x 10^6

When we have to write scientific notation then we have to put a point in the given number so that the number comes between 1 and 9. And after that put the power of the ten to how much point you have moved to get the resultant.

If you move a point in left side then power will be negative but if you move the point to the right side the power will be positive.

The answer is C. 5.000039x10^6.

In order to change something into scientific notation you have to move the decimal place enough times to get the first number to be between 1 and 9. After that, you must count how many space you moved it and that is your exponent. Moving the decimal space to the left gives you a positive exponent. Moving it to the right gives you a negative exponent.

8a - 4b = 20<br>5a - 8b = 62<br><br>What are the values of a and b?​
erastovalidia [21]

Answer:

a=2 , b= (-1)

Step-by-step explanation:

8a-4b=20/×(-2)

5a-8b=62

-16a+8b= -40

5a-8b=62

now -8+8=0 right? so the only parameter that we have is a.

-16a+5a= -40+62

11a = 22/(÷11)

a=2

in order to find b, we will replace a with its value in one of the original equations (it doesn't matter which one you will choose).For instance, I chose the first one.

8×2-4b=20

-4b=20-16

-4b=4/÷(-4)

b= -1

On a piece of paper , graph f(x)=2^x then determine which answer choice matches the graph you drew.
amid [387]

Answer:

The graph in the attached figure

Step-by-step explanation:

we have

f(x)=2^x

This is a exponential function of the form

y=a(b^x)

where

a is the initial value or the y-intercept

b is the base of the exponential function

If b>1 then is a exponential growth function

If b<1 then is a exponential decay function

In this problem

The y-intercept is equal to

For x=0

f(x)=2^0=1

The y-intercept is the point (0,1)

so

a=1

b=2

The value of b is greater than 1

so

Is a growth function

To plot the graph create a table with different values of x and y

For x=-1

f(x)=2^-1=0.5

point (-1,0.5)

For x=1

f(x)=2^1=2

point (1,2)

For x=2

f(x)=2^2=4

point (2,4)

For x=3

f(x)=2^3=8

point (3,8)

For x=4

f(x)=2^4=16

point (4,16)

Plot the y-intercept and the other points and connect them to graph the exponential function

Note that as x increases the value of y increases (exponential growth function)
