Answer:
y = 2 - 5/4x
or
y = 2 - 1.25x
Step-by-step explanation:
Slope-intercept form is y=mx+b, where m=slope and b=y-intercept. Let's make this equation look more like that by isolating y on one side.
5x + 4y = 8
Subtract 5x from both sides.
4y = 8 - 5x
Divide both sides by 4.
y = 8/4 - 5/4x
y = 2 - 5/4x
Answer:
Area= 48 cm²
Step-by-step explanation:
Since the radius is 4, to get area, you must get 4 squared(4 x 4), which is 16. Then, multiply 16 to 3(pi), and the answer is 16 x 3 = 48.
You want to know how long it'll take for the bacteria to grow
to (800/500) = 1.6 times their initial population.
The number of double-times it'll take is
[ log(1.6) / (log(2) ] = 0.6781 .
The double-time for these particular critters is 12 hours,
so it'll take them
0.6781 x 12 hours = 8.137 hours
= 8 hours 8.2 minutes .
