Answers

Using a graph tool

Let's proceed to analyze each case

case a) The equation|-x- 4| = 8 will have two solutions

Is true

The solutions are

x=-12\n x=4

see the attached figure N 1

case b) The equation 3.4|0.5x- 42.1| = -20.6 will have one solution

Is False

The equation has no solution

The term 3.4|0.5x- 42.1|

always will be positive

case c) Is not a equation

case d) The equation |2x- 10| = -20 will have two solutions.

Is False

The equation has no solution

The term |2x- 10|

always will be positive

case e) The equation |0.5x – 0.75| + 4.6 = 0.25 will have no solutions.

Is True

The left side of the equation always will be greater than or equal to 4.6

case f) The equation = 5 will have infinitely many solutions.

Is not a equation

therefore

the answer is

case a) and case e) are true

The air quality index, or AQI, measures how polluted the air is in your city and assigns a number based on the quality of the air. Over 100 is unhealthy. . . Given the following quadratic regression equation, estimate the number of days the AQI exceeded 100 in the year 1988. . . n = 1.76t^2 - 13.32t + 41.00. (let t represent the number of years since 1990. therefore, t = 0 corresponds the year 1990. round to the nearest whole day.). . A. 60 days. B. 75 days. C. 61 days. D. 21 days

Answers

There are several information's already given in the question. The answer to the question can be easily deduced using those given information's. 

From the given question we come to know that
t = -2
Then
n = 1.76t^2 - 13.32t + 41.00
   = [1.76 * (-2)^2] - [13.32 * (-2) + 41
   = 7.04 - ( - 26.64) + 41
   = 7.04 + 26.64 + 41
   = 74.68
   = 75
From the above deduction, we can conclude that the correct option among all the options that are given in the question is the second option or option "B".

Answer:

b. 75 days

The domain of the following relation: R: {(−4, 8), (8, 10), (5, 4), (1, 6), (5, −9)} is{8, 10, 4, 6, −9}

{−4, 1, 5, 8}

{−4, 8, 5, 1, 5}

No domain exists

so lets say you have a number, x

to get to the next counting number, you add one so
x+1 is the next counting number

product means the result of multiplying os
