The aircraft A330 flies at an average speed of 400 miles per hchor. The expression, 400t gives the distance traveled by the airc
Olenka [21]

The expression:

d(t)=400t

gives the distance traveled by the aircraft in t hours, so, for t = 6:

\begin{gathered} t=6 \\ d(6)=400(6) \\ d(6)=\frac{2400mi}{h} \end{gathered}

A pharmacist is filling small empty bottles with cough syrup from a larger bottle. He can solve the inequality to find the numbe
andrey2020 [161]

Let us assume capacity of large bottle = 1000 ml.

And capacity of each small bottle = 25 ml.

Reaming milliliters in large bottle = 250 milliliters.

Number of bottles = x bottles.

Total capacity of large bottle - capacity of a small bottle × number of bottles > Reamining milliliters in large bottle.

Therefore, we can setup an inequality.

1000 - 25 × x > 250.

1000 -25x >250.

Easy!!!
aksik [14]

Step-by-step explanation:

f(g(10))

This is called a composite function.  It's when you plug one function into another.

First, find g(10):

g(x) = √(x-9)

g(10) = √(10-9)

g(10) = √1

g(10) = 1

Then plug that into f(x):

f(x) = -9x - 9

f(g(10)) = -9 g(10) - 9

f(g(10)) = -9 (1) - 9

f(g(10)) = -9 - 9

f(g(10)) = -18
