Hmm... That's hard!

Well, I ended up with 19 7/10 but I'm a bit sure its incorrect. Here's how I got my answer.

First, you look what's in the parentheses. -20 1/2. Hmm. Just that? Then look at the number outside. 4/5. Just subtract 20 1/2 and 4/5. If there was no subtraction sign, you could've just multiplied... but teachers just want to melt your brain...

Find f(0) and f(2) for the given exponential function. f(x) = (1/2)^-x
Aliun [14]
For 0 it will equal 1 because anything to the 0th power is 1 except 0 to the 0.

For 2, It will equal for because when you raise a fraction to the negative power you flip it and that gets rid of the negative number so then you will have 2 to the second and you will get 4.

f (0) = 1, f (2) = 4

Doomtown is 300 miles due west of Sagebrush and Joshua is due west of Doomtown. At 9 a.m. Mr. Archer leaves Sagebrush for Joshua
e-lub [12.9K]
Refer to the diagram shown below.

Let the distance that Sassoon travels is d miles.
Let his average speed be x mph.
The time of travel is from 1 p.m. to 4 p.m., which is 3 hours.
Therefore 
3x = d                            (1)

The distance that Archer travels is (d + 300) miles.
The time of travel is from 9 a.m. to 4 p.m., which is 7 hours.
The average traveling speed is (x + 20) mph, therefore
7(x + 20) = d + 300     
That is,
7x + 140 = d + 300
7x = d + 160                  (2)

Subtract (1) from (2).
7x - 3x = d + 160 - d
4x = 160
x = 40 mph  (Sassoon's average speed)
x+20 = 60 mph (Archer's average speed)
From (1), obtain d = 120 mi

Answer:
Archer's speed is 60 mph.
Sassoon's speed is 40 mph.
