Answer:
No.
It's x^4 - 4x^3 + 7x^2 - 28x.
Step-by-step explanation:
(x - √7 i)(x +√7i)
= x^2 + √7x i - √7x i - 7 i^2
= x^2 - 7 * -1
= x^2 + 7
g(x) = x(x - 4)(x^2 + 7)
= x(x^3 + 7x - 4x^2 - 28)
= x^4 - 4x^3 + 7x^2 - 28x.
Answer:
1.5x ≤ 60
Step-by-step explanation:
He wants to run no more than 60 minutes a day
No more than means Less than or equal to with the inequality sign of ≤
Each lap = 1.5 minutes.
The greatest number of laps Peter could run = x
Therefore, the inequality that best represents the situation and represents x, the greatest number of laps Peter could run in a day
1.5 × x ≤ 60 minutes
= 1.5x ≤ 60
Solving for x
1.5x ≤ 60
x ≤ 60/1.5
x ≤ 40 laps
Hence, the Greatest number of laps = x that he can run is 40 laps
First we need to graph the given values.
there are total 16 data so x-value can be taken as 1,2,3,...,16
given values will be assigned as y-values as shown in attached table.
Now we just graph those points to see the type of skew.
From graph we see that points are very close and almost in the shape of a line. Lines seems to be moving upward when going to the right side.
Hence correct answer will be "positive skew".
A. True B. False it would take 5 hours to go 250 miles going at 50mph C. True going at 50mph in about 3 hours he would have driven 150 miles D. False 300 divide by 50 is 7 but it took him 7 hours to get to his destination so it is false
I may be wrong i used this website here: https://www.timecalculator.net/speed-distance-time-calculator
And this one as well: https://researchmaniacs.com/Calculator/miles-mph-to-time/50/how-long-does-it-take-to-drive-350-miles-at-50-mph.html
Yes yes i did look all of this up i didn't want to steer you wrong ._.
