Answer:
f[g(x)] = 7x2+27
Step-by-step explanation:
This represents the function of f[g(x)] because it replaces the x in f(x) with g(x)
f[g(x)] = 7(x2+2)+13
f[g(x)] = 7x2+14+13
f[g(x)] = 7x2 +27
The first one is irrational because it is a repeating fraction.
the third is square root of 7 is less than 14/5
the fourth is <span>negative 5 over 6, negative 5, negative 31 over 6, negative square root 26

Answer:
Mean
Step-by-step explanation:
If Wanda has 80 baseball cards and Kyle has 110 baseball cards. Given that they know the total value of all their individual base ball cards, the worth of each baseball card will be derived by dividing the Total Worth of the cards by the number of cards. This is an example of Mean. Therefore they should use Mean to compare the worth of the cards.
Illustrative Example
If the Total Value of their cards are $500,
For Wanda, Value Per Card= $500/80 Cards =$6.25 per card
Similarly,
For Kyle, Value Per Card= $500/110 Cards =$4.55 per card
So we can see from this illustration whose card is with an higher price using the mean.
Cost times 1.28 gives total cost
Answer:
0.30
Step-by-step explanation:
Each marker costs 30 cents each (0.30$)
you have to divide the amount of money (6) by the amount of markers (20)
6 ÷ 20= 0.30
