Answer:
This number "four" is the maximum possible number of positive zeroes (that is, all the positive x-intercepts) for the polynomial f (x) = x 5 – x 4 + 3x 3 + 9x 2 – x + 5. Affiliate However, some of the roots may be generated by the Quadratic Formula , and these pairs of roots may be complex and thus not graphable as x -intercepts.
can calculate and graph the roots (x-intercepts), signs, Local Maxima and Minima, Increasing and Decreasing Intervals, Points of Inflection and Concave Up/Down intervals.

Answer:
here you go :)
Step-by-step explanation:
To round 0.833 to the nearest hundredth means to round the numbers so you only have two digits in the fractional part. We use the following rules to round 0.833 to the nearest hundredth: A) If the last digit in the fractional part of 0.833 is less than 5, then simply remove the last the digit of the fractional part.
Answer:
8
Step-by-step explanation:
5 = 40
1 = x
Then we multiply by the rule of crisscrossing
5 x X = 40 x 1
5x = 40 then divide both by 5
X = 8
Domain is how far it travels in the x axis. for this, it would be [0, infinity) usually you’d use an infinity sign, but i can’t find that on my phone. range is same as domain but for y axis. so here it’ll be (-infinity, infinity). you use these [] when you can be on the number. you use there () when you can’t be on the number (or it’s infinity). you use {} when you want to list them.
Answer:
About 84 % of the area is between z equals minus 2 and z equals 2
Step-by-step explanation:
A standard normal distribution refers to a normal distribution with a mean of 0 and a standard deviation of 1.
To find the percentage of area that is between -2<z<2, we are going to use a graphic calculator. We get that P(-2<z<2) = 0.84
Therefore, About 84 % of the area is between z equals minus 2 and z equals 2
