Answer:
15.5
Step-by-step explanation:
-2 7/12 = -31/12
-31/12 ÷ -1/6 = 15 1/2 or 15.5
Answer:
mee too
Step-by-step explanation:
In this question, you have to form the equation given the formula of the volume : L x W x D
L = W+5
W = W
D = W-1
(W+5)(W)(W-1) = 20
(W^2+5W)(W-1) = 20
W^3+4W^2-5W-20 = 0
Get the roots by factoring it out.
<span>(w +4) *(w +2.236) *(w -2.236)
</span>
So the roots are: -4, -2.236, 2.236.
Since we're talking about dimensions, let's use the positive root..
L = 7.24
W = 2.24
D = 1.24

Step-by-step explanation:
Hi there!
<u>What we need to know:</u>
- Slope-intercept form: where m is the slope and b is the y-intercept (the value of y when the line crosses the y-axis)
- Parallel lines have the same slope (m) and different y-intercepts (b)
<u>1) Determine the slope (m)</u>
Rearrange this equation in slope-intercept form (so it's easier for us to identify the slope)
Subtract 6x from both sides to isolate 2y
Divide both sides by 2 to isolate y
Now, we can tell clearly that -3 is in the place of m. Therefore, because parallel lines have the same slope, we know that the line we're solving for will also have a slope of -3. Plug this into :
<u>2) Determine the y-intercept</u>
Plug in the given point (-1,7)
Subtract 3 from both sides
Therefore, the y-intercept of the line is 4. Plug this back into :
I hope this helps!
Answer:
Maximum number of turns: 3
Step-by-step explanation:
1. By definition, a polynomial of degree, has a maximum turning points of .
2. Therefore, if you have the polynomial given in the problem, which is a polynomial of degree 4 (, the maximum number of turns can be obtained as following:
3. Therefore, you can conclude that the maximum number of turns are 3.
