Answer:
viii. 2x(1 - 2x)(1 + 2x)(1 + 4x²)
ix. 4xy
Step-by-step explanation:
viii. 2x - 32x⁵
= 2x(1 - 16x⁴)
= 2x(1² - (4x²)²)
= 2x(1 + 4x²)(1 - 4x²) ( a² - b² = (a + b)(a - b))
= 2x(1 + 4x²)(1² - (2x)²)
= 2x(1 + 4x²)(1 - 2x)(1 + 2x)
ix. (x+y)² - (x - y)²
= (x+ y + x - y)( x + y - x + y)
= 2x x 2y
= 4xy

The faculty of a certain four-year college consists of 179 teachers. There are 663 first-year students. The student-to-faculty ratio for the entire college is 15 to 1. What is the total number of second-, third-, and fourth-year students?
A 1,989
B 2,022
C 2,652
D 2,685
9514 1404 393
Answer:
B. 2,022
Step-by-step explanation:
The student/faculty ratio tells you the total number of students in the school is ...
(15 students/teacher)×(179 teachers) = 2685 students
If 663 of those are first-year, then the number of upper-level students is ...
upper-level students = total students - first-year students
upper-level students = 2685 -663 = 2022
The total number of upper-level students is 2,022.

2. The German Shepard actually weighs 28 pounds. Lisa thought the
dog weighed 44 pounds. What is the percent error?
Answer:
Lisa's percentage of error regarding the weight of the dog was 57.14%.
Step-by-step explanation:
Given that the German Shepard actually weighs 28 pounds, but Lisa thought the dog weighed 44 pounds, to determine what is the percent error the following calculation must be performed:
28 = 100
44 = X
(44 x 100) / 28 = X
4,400 / 28 = X
157.14 = X
157.14 - 100 = 57.14
Thus, Lisa's percentage of error regarding the weight of the dog was 57.14%.

A towns population went from 40,000 to 50,000. What was the percent of change in the population?
Answer:
The percent of change in the population was of 25%.
Step-by-step explanation:
Percent change:
The percent change is given by the change multiplied by 100, and divided by the initial value.
A towns population went from 40,000 to 50,000.
Change: 50000 - 40000 = 10000
Initial value: 40000
10000*100/40000 = 25%
The percent of change in the population was of 25%.

What is Unit of Measurement?A Unit of measure is the actual unit in which the associated values are measured.
Given,
If you jog 8 times around a track that is 600 meters long,
We need to find how many kilometers you have covered.
8 times around a track that is 600
It means we have to multiply eight with six hundred.
8×600
=4800
We know that 1 km is 1000 m
So divide 4800 by 1000 to find in kilometers
4800/1000=4.8km
Hence If you jog 8 times around a track that is 600 meters long, Then 4.8 Kilometers you have covered.
