Probably the easiest way to do this is to use synthetic division. We already know one of the zeros of the quadratic so we can use that number to find the other zero. If the point is (4, 0), then when y = 0, x = 4. Thus, 4 is a zero. Put 4 outside the "box" and put the coefficients from the quadratic inside, like this: 4 (1 -1 -12). Draw a line and bring down the first one under it. Multiply that 1 by the 4 to get 4. Put that 4 up under the -1 and add to get 3. Multiply 3 by 4 to get 12. Put that 12 up under the -12 and add to get 0. The numbers left under the line are the coefficients for the next polynomial, called the depressed polynomial, and this polyomial is one degree less than the one we started with. Those coefficients are 1 and 3. Therefore, the polynomial is x + 3 = 0. That means that the other zero, or x-intercept, is x = -3.
Answer:
1 = m - 2/9 + 7/10
Step-by-step explanation:
We have to, a wall represents unity, therefore to climb a wall, it would then be 1/1 of that wall.
They tell us that the majority has risen, they do not tell us how much, therefore, we will assume that the majority with a value m.
So, when it fell, it lost 2/9 of the wall but then resumed 7/10, that is:
- (2/9) + (7/10) = -20 + 63/90 = 43/90
That is, it had an advance of 43/90 of the wall, we know that the wall is 1/1, therefore:
p = m + 43/90
m = 1/1 - 43/90 = 90-43 / 90
m = 47/90
It means that most of the wall is 47/90
The function would be
1 = m - 2/9 + 7/10
Question 36.
Given the function:
Let's graph the function.
Let's graph the function using desmos, then label the following:
• 1. Points of inflection
,
• 2. Critical points
,
• 3. Local extremes
• 4. Asymptotes
• The inflection points are the points the function changes concavity.
,
• The local minimum is the point where the minimum value is obtained.
,
• The critical point is the point the function changes direction.
• There is no vertical or horizontal asymptote.
ANSWER:
• The inflection points are the points the function changes concavity.
,
• The local minimum is the point where the minimum value is obtained.
,
• The critical point is the point the function changes direction.
• There is no vertical or horizontal asymptote.
Answer:
if they are proportional he will give away 20
