I believe GCF is 36a^2b+6ab^3
1) 8 turning points means 8 vertices, which implies minimum degree 9 (when the polynomial is x^2 the degree is 2 and it has one turning point).
2) 5 turning points means minimum degree 6, 3 zeros means minimum degree 3, the multiplication implies minimum degree 6+3 = 9
3) 5 times crossing the x - axis is 5 zeros, then the minimum degree is 5.
4) f(x)=x^14 + x^6 + x^9 + x^3,maximum number of turning points 14 -1 = 3 (remember one less than the grade is the maximum posible number of turning points, but it could be less, for example f(x) = x^2 has one turning point).
Answer:
The statement is not reasonable.
Step-by-step explanation:
Josefina gave away 130% of her stamp collection.
We cannot give more than what we have.
lets understand it mathematically.
suppose i have x stamp.
according to question, i have to give 130% of my stamp collection
130% of x = 130/100 x = 1.3x
so, i have to given 1.3x stamp while i do have only x stamp which does not make any sense.
maximum i can give is x stamp.
x stamp in percentage of my total stamp collection which is also x will be
= x/x*100 = 100%
Thus, maximum one can give is 100% of what he has.
Thus, we can say that Josefina gave away 130% of her stamp collection is not reasonable.
Answer
1.8/125 cm³
2. 13
3a. x³-17
3b. 3x-5
5. A) Power
Step-by-step explanation:
1. (2/5)³= 2/5 * 2/5 * 2/5
= 4/25 *2/5
=8/125
2. b³+(10-a)
= (2)³ + (10-5)
=(2*2*2) + (5)
= 8 + 5
= 13
3a. a number cubed = x³
seventeen less than = -17
3b. three times a number = 3x
five = 5
5. product is when two values are multiplied (13 and 3+x)
Answer:
Blue pens: 30%
Black pens: 44.8%
Pencils: 25.2%
400 people: 280 people
Step-by-step explanation:
Begin by adding up everyone:
75+112+63= 250
Percentage of blue pens:
75/250= 30.0%
Percentage of black pens:
112/250= 44.8%
Percentage of pencils:
63/250= 25.2%
400 people:
280 people
