Answer:

Below in bold.

Step-by-step explanation:

speed = distance / time

2.4 * 10^4 = 3.2 * 10^6 /time

Time = 3.2 * 10^6 / 2.4 * 10^4

= 3.2/2.4 * 10^(6-4)

= 1.3333.. * 10^2 hours

= 133 hours  ( to 3 significant figures).

Factor the expression.
tiny-mole [99]
B. (k+10f)(k-5f) you can tell in 2 ways.  1. if the second sign is neg then the signs in the factors are going to be one neg and one positive so that knocks out C and D.  Then you look at the second term and since the 5 is positive then the 10 has to be positive so you end up with a positive 5kf.

The second way is to FOIL them out.  When you check B you get k^{2} -5kf+10kf- 50f^{2} combine your like terms and you have your original expression of k^{2} +5kf-50 f^{2}

Hope that helps

Solve for x<br><br> (picture is included below)
Anna11 [10]

Solve for x:

1.

4x - 7 = 3

Add 7 to both sides

4x = 10

Divide both sides by 4

x = 10/4

Simplify:

x = 5/2

Answer for question 1: x = 5/2

2.

13 + 2x/3 = 15

Multiply both sides by 3

39 + 2x = 45

Subtract 39 from both sides

2x = 6

Divide both sides by 2

x = 3

Answer for question 2: x = 3

3.

10x + 7 = 15

Subtract 7 from both sides

10x = 8

Divide both sides by 10

x = 8/10

Simplify

x = 4/5

Answer for question 3: x = 4/5

How to graph an exponential function
irina1246 [14]

Step-by-step explanation:

Exponential function is given by general form y=ab^x

Where a and b are constants.

say a=1 and b=2 then we can write function as :

y=1*2^x

or y=2^x

To graph this or any exponential function, we just need to find some points then join them by a curved line.

Like plug x=0, 1, 2,... into above function and find points:

plug x=1

y=2^x=2^1=2

Hence point is (1,2)

Find more points similarly then graph them to get the graph as shown below:
