Answer:
-1.0, 1.0
Step-by-step explanation:
The given polynomial function is
f(x) = 2 {x}^{4} - {x}^{3} + x - 2
According to the Rational Roots Theorem, the possible roots of this function are;
\pm1,\pm \frac{1}{2}
We now use the Remainder Theorem to obtain;
f(1) = 2 {(1)}^{4} - {(1)}^{3} + 1 - 2
f(1) = 2 - 1+ 1 - 2 = 0
f( - 1) = 2 {( - 1)}^{4} - {( - 1)}^{3} - 1 - 2
f( - 1) = 2 + 1 - 1 - 2 = 0
But;
f( \frac{1}{2} ) = - 1.5
f( - \frac{1}{2} ) = - 2.25
Since f(1)=0 and f(-1)=0, the real zeros to the nearest tenth are:
-1.0 and 1.0
Does y = 1 because x = 6 and xy=6 so 6 time 1 =6? not sure just what i think
Answer:
826.8 hours
Step-by-step explanation:
Given data
Lenght of video= 234minutes
number of times watched= 212 times
Based on the information given, we can estimate the number of hours spent watching the video
=234*212
=49608 minutes
in hours
=49608/60
=826.8 hours
in days
=826.8/24
=34.45 days
Answer:
y=-1/2n+44
Step-by-step explanation:
The number of bean stalks, n, represents the x values
The yield, y, represents the y values
After reading the problem, we have two coordinates: (30,29) and (32, 28) Because this problem is asking for y=mn+b, we have to find the slope. How do we find the slope? We do so by using the slope formula y2-y1/x2-x1. Now let's input the coordinates into this formula.
1.) 28-29/32-30 = -1/2
Let's plug -1/2 into y=mn +b
2.) y=-1/2n+b
Now we have to find what b ( y intercept) equals. To find B, we plug a coordinate into x and y. Let's use (30,29)
3.) 29 = -1/2(30)+b
29 = -15 +b
44 = b
We have now found the linear relationship form for this problem: y=-1/2n +44
Answer:
A about ten percent of the town is left handed
Step-by-step explanation:
20 of 200 is ten percent and this town could be an outlier in left handed populations.
