Answer:
19.
h=0, the result is 1000×2⁰ = 1000
this is the population of bacteria the excitement started with at the very beginning.
h=-3, the result is 1000×2-³ = 1000/(2³) = 1000/8 = 125
this is a calculation 3 hours backwards from the very start of the experiment, saying that if we started the experiment 3 hours earlier, this would have had to be the starting population of the bacteria so we would arrive at the same amount of population at any given time (value of h).
20.
D 25x⁶
Step-by-step explanation:
for 19 there is not more explanation. it is all ashtray in the answer.
for 20 we see that we are dealing with a square, so ask 4 sides have the same length.
one side is 5x³.
the area of a square is simply side².
so, here (5x³)² = 25x⁶
Answer:
5 degrees
Step-by-step explanation:
Complementary angles sum up to 90 degrees.
If one angle is 85 degrees, then its complement is (90 - 85), or 5, degrees.
By pythagoras
53^2 = h^2 + 45^2 where h is the height of the television.
h^2 = 53^2 - 45^2 = 784
h = sqrt 784 = 28 inches Answer
Answer:
2/3
Step-by-step explanation:
Slope is rise over run which is 2/3
$1.00 per 8 ounces
This is not the unit rate , because this $1.00 is the rate for 8 units , not for 1 unit , while all other options have rate for 1 unit only.
