The function f(x) will be sometimes positive and sometimes negative on the interval
Option (3) is correct.
What is a function?An arrangement known as a function connects inputs to essentially one output.
In other words, a function is a relationship between variables, and the nature of that relationship—for example, y = sinx and y = x +6—defines the function.
Given function:
f(x) = (x - 5) (2x - 7) (7x - 3)
The term (x - 5) will be negative if x < 5.
The term (2x - 7) will be negative if x<3.5
So, If x = 4, (x - 5) will be negative but (2x - 7) will be positive, resulting in a negative overall value.
Therefore, if x = 3, then (x - 5) will be negative, as well as (2x - 7), making the whole value negative.
Hence, the function f is sometimes positive and sometimes negative on the interval.

How much must be added to each of the three number 1, 11, and 23 so that together they form a geometric progression?
Answers
Answer:
49
Step-by-step explanation:
Let the three numbers be a1, a2, a3
Let the number to be added to form a geometric progression = x
a1 = 1 + x ; a2 = 11 + x ; a3 = 23 + x
For a geometric progression :
a2 = a1 * r
a2 = (1+x)r
11+x = (1+x)r - - (1)
r = (11+x) / (1+x) ---(1)
a3 = a2 * r
a3 = (11+x)r
23+x = (11+x)r - - -
r = (23+x) / (11+x) - - (2)
Equate (1) and (2)
(11+x) / (1+x) = (23+x) / (11+x)
(11+x) * (11+x) = (23+x) * (1+x)
121 + 22x + x² = 23 + 24x + x²
121 + 22x + x² - x² - 24x - 23 = 0
98 - 2x = 0

When building a house, the number of days required to build is inversely proportional to with the number of workers. One house was built in 147 days by 4 workers. How many days would it take to build a similar house with 42 workers?
Answers
Answer:
14
Step-by-step explanation:
[tex]147 \times 4 \div 42 = 14[/tex]
It would take 14 days to build a similar house with 42 workers
What is the fundamental principle of multiplication?Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
We are given that the number of days required to build is inversely proportional to with the number of workers.
One house was built in 147 days by 4 workers.
So,
147 x 4 = 588
Now the days to build a similar house with 42 workers
588/ 42 = 14

Triangle Inequality Theorem
Let y and z be two of the side lengths of a triangle. The length of the third side x cannot be any number. It must satisfy all the following restrictions:
x + y > z
x + z > y
y + z > x
Combining the above inequalities, and provided y>z, the third size must satisfy:
y - z < x < y + z
The two side lengths given in the triangle of the figure are y=8.5, z=8.0, thus the possible values of x lie in the interval
8.5 - 8.0 < x < 8.5 + 8.0
0.5 < x < 15.5
