Step-by-step explanation:

When studying sets of numbers students have certain misconception

1) the correct of writing the tabular notation form

2) the differentiation between sets ( example certain sets have zero and certain do not have a zero - example 2 all integers are rational numbers but all rational numbers are not integers)

3) types (kinds ) of sets . ( onto - into and binary relation)

4) Domain and Range of sets

A rectangle room is 12 1/2 feet long and 10 1/3 feet wide. what is the area of the room

Veronika [31]

Answer:

129 1/6 feet

Step-by-step explanation:

Formula for area is L*W

1. convert the mixed numbers to improper fractions

12 1/2 feet = 25/2

10 1/3 feet = 31/3

2. multiply numerator by numerator (25*31 = 775

3. multiply denominator by denominator (2*3=6

4. convert improper fraction 775/6 into a mixed number by dividing 775 by 6.

5. 775/6 = 129 r. 1 or 129 and 1/6

Evaluate the piecewise function for the given values.

adoni [48]

Answer:

f(-3) = -2

f(-2.6) = -2

f(0.6) = 2.4

f(4.5) = 8.5

Step-by-step explanation:

(Whole question:

Evaluate the piecewise function for the given values.

Find f(-3), f(-2,6), f(0.6), and f(4.5) for f(x)={ -2 If x ≤ 0 4x. If 0 <x <1. x + 4. If x ≥ 1)

As the piecewise function shows, the function f(x) has the value of -2 for values of x lesser or equal than 0, has the value of 4x if the value of x is between 0 and 1, and has the value of x+4 for values of x greater or equal than 1.

So, for f(-3), the value of x is lesser than 0, so we have that f(-3) = -2

For f(-2.6), the value of x is lesser than 0, so we have that f(-3) = -2

For f(0.6), the value of x is between 0 and 1, so we have that f(0.6) = 4*0.6 = 2.4

For f(4.5), the value of x is greater than 1, so we have that f(4.5) = 4.5 + 4 = 8.5

The perimeter of a rectangle is 44 m. The length is 4 m more than the twice the

mojhsa [17]

Step-by-step explanation:

perimeter is given by

p=2L +2W

but from the expression;The length is 4 m more than the twice the width

is written as L =4+2W

putting it in the formula

p= 2(4+2W) +2W

but perimeter was given as 44m

44= 8+4w+2w

44=8+6w

44-8=6w

36=6w

dividing through by 6

w=36/6

w=6m

thus, the width is 6m

put it in the expression L =4+2W to get the length

L =4+2(6)

L=4+12

L=16m

thus the length is 16m
