What is piecewise function?Piecewise function is a function built from pieces of different functions over different intervals.
The given function is: f(x)= [tex]\left \{ {{2x, \;\; x < 1} \atop {-4, \;\; x=1} \right \atop {x+8, \;\; x > 1}[/tex]
As, piecewise function is a function built from pieces of different functions over different intervals.
As per the above discussion we can say that,
Take function for limit 1 minus, as f(x) = 2x
put x=1,
f(x)=2, exits.
Take function for limit 1 plus, as f(x) = x+8
put x=1,
f(x)=9, exits.
As both satisfies the definition and part (A)
As well as both limit exist and are not equal.
So, Limit of f (x) = 2 as x approaches 1 minus. Limit of f (x) = 9 as x approaches 1 plus for the given f(x).

the length is 3 inches less than twice the width and the permiter is 42 inches. Find dimensions
Answer:
Here
Step-by-step explanation:
length = x
width = 2x - 3
Perimeter = 2length + 2 width
2x + 2(2x - 3) = 42
2x + 4x - 6 =42
6x - 6 = 42
Add 6 to both sides
6x = 48
Divide both sides by 6
x = 8
Length = 8 inches
Width = 2(8) - 3 = 16-3 = 13 inches

The area of a square floor on a scale drawing is 25 square centimeters, and the scale drawing is 1 centimeter:5 ft. What is the area of the actual floor? What is the ratio of the area in the drawing to the actual area?
Answer:
[tex]625ft^{2}[/tex]
Step-by-step explanation:
First get the l by finding the square root of the area
[tex]\sqrt{25}[/tex] = 5cm
since 1cm = 5ft
what about 5cm =?
(5cm×5ft)/1cm
l=25ft

What is slope intercept form of line?The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
Let x represents the number of minutes and y represents the number of miles.
Slope =2-1/16-8
=1/8
We have to find the y intercept
1=1/8(8)+b
b=0
y=1/8x is the equation.
We have to find the time taken to run 4 miles
So y=4
4=1/8x
x=32
Hence, it would take 32 minutes to run 4 miles.

A) 83%
B) 93%
C) 7%
D) 17%
Answer:
The Answer is A. 83%
Step-by-step explanation:
The Probability a certain event= 1- Probability of that certain event not to happen.
According to this, it is true that:
Probability (not rolling 5)=1- P(rolling 5) = 1=60/350= 1-6/35 =35-6/35=29/35=0.83
Ms. Parker determined that the mean test score in her first-period class
was 81 with a standard deviation of 7.06. The mean test score in her
second-period class was 88 with a standard deviation of 8.24. Which
conclusion can be made about her students' test scores?
A Period 2 had scores that were less spread out around the mean than
Period 1.
B. Period 1 had scores that were less spread out around the mean than
Period 2.
C. Period 2 had scores that were less spread out around the median than
Period 1.
D
Period 1 had scores that were less spread out around the median than
Period 2.
Answer:
B. Period 1 had scores that were less spread out around the mean than
Period 2
Step-by-step explanation:
Because the standard deviation of Period 2's scores is greater than that of Period 1's, the test scores for Period 2 are going to be more spread out than Period 1's test scores. B is the most logical choice in this case.

[tex] \displaystyle V_{ \text{H - prism}} = 351 {yd}^{3} [/tex]
Step-by-step explanation:
we are given a hexagonal prism
we want to figure out the Volume
remember that,
[tex] \displaystyle V_{ \text{H - prism}} = {a}^{} sh[/tex]
where a is the asymptote ,s is the side length and h is the height
given that,s=9,a=7.8 and h=5
substitute:
[tex] \displaystyle V_{ \text{H - prism}} = {7.8}^{} \times 9 \times 5[/tex]
simplify multiplication:
[tex] \displaystyle V_{ \text{H - prism}} = 351[/tex]
hence the Volume of the given figure is 351 yd³

An IQ test is designed so that the mean is 100 and the standard deviation is 19 for the population of normal adults. Find the sample size necessary to estimate the
mean IQ score of statistics students such that it can be said with 95% confidence that the sample mean is within 7 IQ points of the true mean. Assume that o = 19 and
determine the required sample size using technology. Then determine if this is a reasonable sample size for a real world calculation.
Step-by-step explanation:
To solve this question, we use this formula:
x± s t_(1−c)/2 / √n = 5
(1 - c)/2 = (1 - 0.95) / 2 = 0.025
Using a t score calculator at this value, at the 95% confidence internval,
t = 0.5080, So
100 - 19(0.5080) / √n = 5
Solving for n
n = 97
a) 97
b) yes
