8w^2=50
= w^2= (50÷8)
= w^2= 6.25
=w = √6.25
w= 2.5
Answer:
neither
Step-by-step explanation:
they are parallel when they have the same slope and perpendicular when the slope is completely different
Let the number of cups of onions Katrina still needs to chop = x
She has already chopped the onions = cups ≈ cups
So total amount of chopped onions = cups
Since, onion soup recipe calls for the chopped onions = cups ≈ cups
Therefore, equation which shows the number of cups of onions to be chopped more will be,
We further solve this equation for the value of x,
x =
= cups
≈ cups
we have a exponential function of the form
where
y is the population of bacteria
a is the initial value
r is the rate of growth
x is the number of hours
we have
a=3,000 bacteria
For x=2, y=3,300
substitute
Apply square root both sides
substitute in the equation
<u><em>Predict how many bacteria will be present after 16 hours</em></u>
For x=16 hours
1,4(0,5x + 4,2y) - 3,5(0,2x - 1,5y)
1,4.0,5x + 1,4.4,2y - 3,5.0,2x + 3,5.1,5y
0,7x + 5,88y - 0,7x + 5,25y
0,7x - 0,7x + 5,88y + 5,25y
11,13y
