Allison is making fruit drinks for her friends.
Svetllana [295]

The number of cups of fruit Allison will need is = 4 ⅘ cups of fruits

<h3>Calculation of total quantity of fruits</h3>

The quantity of strawberries needed for each fruit drink= 3/5 cup

The quantity of blueberries needed for each fruit drink = 1/5 cup

Therefore the total quantity of fruits needed for each drink = 3/5 + 1/5

= 4/5

If 4/5 = 1 fruit drink

X = 6 fruit drinks

Make X the subject of formula,

X = 4/5 × 6

X = 24/5

X= 4 ⅘

Therefore, the number of cups of fruit Allison will need is = 4 ⅘ cups of fruits

laila [671]

Answer:

As x increases , y decreases then increases

Step-by-step explanation:

There are two situation

1> when x < 0

2> when x>= 0

let see

when x < 0

we see that as value of x moves from -ve value towards zero (i.e x is increasing) then value of y is decreasing( value of x has moved from positive side of y( above x-axis) towards negative side of (below x-axis)\

Thus, we can say that

for x < 0

As x increases , y decreases

________________________________________

when x>= 0

we see that as value of x moves from 0  towards +ve  value(i.e x is increasing) then value of y is increasing( value of x has moved from negative side of y( below x-axis) towards positive side of (above x-axis)\

Thus, we can say that

for x >= 0

As x increases , y increases

_________________________________________

combining both observation it can be said that

As x increases , y decreases then increases which is equal to fouth option

The limit of sqrt(9x^4 + 1)/(x^2 - 3x + 5) as x approaches infinity is
Lerok [7]

Answer:

B. 3.

Step-by-step explanation:

At the limit we can take the numerator  to be √(9x^4) = 3x^2

The function is of the form ∞/ ∞ as x approaches ∞ so we can apply l'hopitals rule:

Differentiating top and bottom we have   6x / 2x - 3. Differentiating again we get 6 / 2 = 3.

Our limit as x  approaches infinity  is 3.
