8 0

Answer:

192 yd³

Step-by-step explanation:

The volume of a rectangular pyramid is given by the formula:

$V=\frac{1}{3} lwh\text{ where } l \text{ is the base length, }w \text{ is the base width, and }h \text{ is the pyramid height}$

In this case: $l = 9, w=8, h = 8$

$\therefore V=\frac{1}{3}(9\text{ yd})(8\text{ yd})(8\text{ yd})=192\text{ yd}^3$

Find the midpoint of the line joining A (3,5) and B(1,3)

MaRussiya [10]

Answer:

(-1 , -1)

Step-by-step explanation:

$x_1= 3 \\ y_1= 5 \\ x_2=1 \\ y_2= 3$

$midpoint \: = ( \frac{x_2 - x_1}{2} \: \frac{y_2 -y_1}{2} )$

$=( \frac{1 - 3}{2} \: \frac{3 - 5}{2} ) \\ = ( \frac{ - 2}{2} \: \frac{ - 2}{2} ) = \\ ( - 1 \: - 1)$

ASAP can somebody answer this? SCREEN SHOT OF QUESTION ATTACHED

Natasha2012 [34]

Answer:

A. $(-\infty, -4]\ or\ (2,\infty)$

Step-by-step explanation:

Given:

The inequality is given as:

$x\leq-4\ or\ x>2$

Now, consider the first inequality

$x\leq-4$

Here, 'x' is less than or equal to -4. The values that are less than -4 are -5, -6, -7... so on. The inequality used is 'less than or equal to'. This means that -4 is included in the solution. So, we use a square bracket (closed interval) at the other end.

The inequality in notation form is thus, $(-\infty,-4]$

Now, consider the other inequality $x>2$

The values of 'x' are greater than 2. The values that are greater than 2 are 3, 4, 5... and so on. Also, 2 is not included in the solution. So, we use open interval on either side.

Therefore, $x>2$ in interval notation form is $(2,\infty)$

There is a conjunction 'or' used in the inequality. Therefore, the answer is:

A. $(-\infty, -4]\ or\ (2,\infty)$

The graph on the number line is shown below.
