Answer:

1356cm3

Step-by-step explanation:

when the stone is dropped in to the water the new height is 17.4cm(14+3.4)

find the volume when the height is 14cm and when the height is 17.4cm

24*14*17.4=4716

24*14*14=3360

then subtract the two volumes

4716-3360=1356cm3

Answer:

816 cm^3

Step-by-step explanation:

First you want to find the volume of the container with the stone, and then without the stone.

The formula for finding the volume of a rectangular container is V= l x w x h

We substitue in:

With stone:

V= 24cm x 10 cm x (14+3.4 cm)

V= 4,176 cm^3

Without stone:

V= 24 cm x 10 cm x 14 cm

V= 3,360 cm^3

Then, you want to subtract the two volumes to get the stone by itself.

4,176 - 3,360= 816 cm^3

Hope this helps!

PS- I think the answer above me got their numbers mixed up, but they had the right idea.

If the parent function is f(x) =mx+b, what is the value 9f the parameter b for the line passing through the pings (2,0) and (0,-
andrew11 [14]

Answer:

B) -4

Step-by-step explanation:

m= (0 - (-4)) / (2 - 0) = 4 / 2 = 2

f(2) = 2 * 2 + b = 0

f(0) = 2 * 0 + b = -4

b = -4

Given f(x) =
sergejj [24]

Answer:

A

Step-by-step explanation:

We are given the function:

\displaystyle f(x) = \left\{        \begin{array}{ll}            2\cos(\pi x) \text{ for }  x \leq -1 \\ \\          \displaystyle   \frac{2}{\cos(\pi x)}\text{ for } x > -1        \end{array}    \right.

And we want to find:

\displaystyle \lim_{x\to -1}f(x)

So, we need to determine whether or not the limit exists. In other words, we will find the two one-sided limits.

Left-Hand Limit:

\displaystyle \lim_{x\to-1^-}f(x)

Since we are approaching from the left, we will use the first equation:

\displaystyle =\lim_{x\to -1^-}2\cos(\pi x)

By direct substitution:

=2\cos(\pi (-1))=2\cos(-\pi)=2(-1)=-2

Right-Hand Limit:

\displaystyle \lim_{x\to -1^+}f(x)

Since we are approaching from the right, we will use the second equation:

=\displaystyle \lim_{x\to -1^+}\frac{2}{\cos(\pi x)}

Direct substitution:

\displaystyle =\frac{2}{\cos(\pi (-1))}=\frac{2}{\cos(-\pi)}=\frac{2}{(-1)}=-2

So, we can see that:

\displaystyle \displaystyle \lim_{x\to-1^-}f(x)=\displaystyle \lim_{x\to -1^+}f(x) =-2

Since both the left- and right-hand limits exist and equal the same thing, we can conclude that:

\displaystyle \lim_{x \to -1}f(x)=-2

Our answer is A.
