Answer:

81 cubic feet of wood

Step-by-step explanation:

Divide it into 5 sections, each 3 feet long because it is 15 feet long.

(1*3*3) + (2*3*3) + (3*3*3) + (2*3*3) + (1*3*3) =

9 + 18 + 27 + 18 + 9 = 81

Find the image of U'( -8 , 1) after a translation along < 2 , 0 > and a reflection in the x axis
Lana71 [14]

Given:

The point is U'(-8,1).

It is translated along <2,0> and reflected across the x-axis.

To find:

The image of U'.

Solution:

The given point is U'(-8,1).

It is translated along <2,0> . So, the rule of translation is:

(x,y)\to (x+2,y+0)

U'(-8,1)\to U_1(-8+2,1+0)

U'(-8,1)\to U_1(-6,1)

Then, it is reflected across the x-axis. So, the rule of reflection is:

(x,y)\to (x,-y)

U_1(-6,1)\to U''(-6,-1)

The image of U'( -8 , 1) is U''(-6,-1).

Therefore, the correct option is A.

Jerry has taken a random sample of students and determined the number of electives that each student in his sample took last yea
loris [4]
The sample proportion of the the students that took fewer than the mean number of electives is given by the number of people who took less that the mean number of electives (i.e. 7.63) divided by the total number of students in the sample (i.e. 19). The total number of people who took less than 7.63 electives is 10. Therefore, the required sample proportion is 10 / 19.
