To solve: 
Simplify 128x^5/8x first
16x^4

then divide by 1/4

Answer:

2x^4 is the simplified expression

Step-by-step explanation:

We have been given an expression:

(\frac{128x^5}{8x})^\frac{1}{4}

First simplify the terms inside the parenthesis we divide 128 by 8 we get:

(16x^4)^\frac{1}{4}

16 can be written as 2^4 so the given terms become

((2^4)(x^4))^\frac{1}{4}

powers will get cancel because 4\cdot \frac{1}{4}=1 hence, we get:

2x^4 is the simplified expression.

Determine if the described set is a subspace. Assume a, b, and c are real numbers. The subset of R3 consisting of vectors of the
Arte-miy333 [17]

This question is incomplete, the complete question is;

Determine if the described set is a subspace. Assume a, b, and c are real numbers.

The subset of R³ consisting of vectors of the form \left[\begin{array}{ccc}a\\b\\c\end{array}\right] , where abc = 0

  • The set is a subspace
  • The set is not a subspace

Answer:

Therefore; The set is not a subspace

Step-by-step explanation:

Given the data the question;

the subset R³;

S = {  \left[\begin{array}{ccc}a\\b\\c\end{array}\right] , where abc = 0 }

we know that a subset of R³ is a subspace if it stratifies the following properties;

  1. it contains additive identity
  2. it is closed under addition
  3. it is closed under scales multiplication

Looking at the properties, we can say that it is not a subspace

As;

         u = \left[\begin{array}{ccc}1\\1\\0\end{array}\right] ∈ S       and v = \left[\begin{array}{ccc}0\\1\\1\end{array}\right]  ∈ S

As    1×1×0=0                          0×1×1=0

But   u+v = \left[\begin{array}{ccc}1+0\\1+1\\0+1\end{array}\right] = \left[\begin{array}{ccc}1\\2\\1\end{array}\right]  ∉  S     as 1×2×1 ≠ 0

Hence, it is not closed under addition.

Therefore; The set is not a subspace

At Jefferson Elementary School, the number of teachers and students (kindergarten through sixth grade) totals 510. The ratio of
Taya2010 [7]

Answer:

C. 28 fewer

Step-by-step explanation: Total population of students and teachers = 510

Students : teacher = 16 : 1

Population of students = 16/17 × 510 = 480 students

Number of kindergarten students = 1/5 of 480 = 1/5×480 = 96

Number of grade 5 and 6 students = 1/3 of (480 - 96) = 1/3×384 = 128

Number of grade 1 and 2 students = 1/4 of 480 = 1/4×480 = 120

Number of grade 3 and 4 = 480 - (96+128+120) = 480 - 344 = 136

Number of grade 3 students = 136/2 = 68

Number of kindergarten students = 96

Therefore, the number of students in grade 3 is 28 (96 - 68 = 28) fewer than the number of students in kindergarten
