Answer:

As x → -∞, f(x) → 0.5; as x → ∞, f(x) → 0.5

Step-by-step explanation:

Given function:

$f(x)=\dfrac{4x-7}{8x+8}$

<u>Asymptote</u>: a line that the curve gets infinitely close to, but never touches.

As the degrees of the numerator and denominator of the given function are equal, there is a horizontal asymptote at $y=\dfrac{a}{b}$ (where a is the leading coefficient of the numerator, and b is the leading coefficient of the denominator). This is the end behavior.

$\textsf{Horizontal asymptote}:y=\dfrac{4}{8}=\dfrac{1}{2}$

This is because as $x \rightarrow \infty$ the -7 of the numerator and the +8 of the denominator become negligible. Therefore, we are left with:

$f(x) \rightarrow \dfrac{4x}{8x}$

Therefore:

$\textsf{As }\:x \rightarrow - \infty, f(x) \rightarrow 0.5$

$\textsf{As }\:x \rightarrow \infty, f(x) \rightarrow 0.5$

There are 280 pieces of fruit in a fruit salad. There are twice as many raspberries as blueberries, three times as many grapes a

dedylja [7]

Answer:

64 cherries

Step-by-step explanation:

Given that

There are 280 pieces of fruit in a fruit salad

There are twice as many raspberries as blueberries,

three times as many grapes as cherries,

and four times as many cherries as raspberries

We need to find out the number of cherries in the fruit salad

So,

Let us assume the blueberries be x

So, the raspberries be 2x

Cherries be 8x

And, grapes be 24x

Now

x + 2x + 24x + 8x = 280

35x = 280

x = 8

hence, the No of cherries in the salad

= 8 x

= 8(8)

= 64 cherries

Answer: 8

Step-by-step explanation:

Given: A bag contains three red marbles, two green ones, one lavender one, two yellows, and two orange marbles.

Total marbles other than green = 8

Total marbles other than green and yellow = 6

Then the number of sets of seven marbles include at least one yellow one but no green ones:-

$^{2}C_1\times^{6}C_6+ ^2C_2\times^6C_5\\\\= 2\times 1+1\times6\\\\=2+6=8$

Number of sets of seven marbles include at least one yellow one but no green ones = 8
