Answer:
y=x^2+2
Step-by-step explanation:
Quadratic function has a general function:
And you can calculate the axis of symmetry with:
x1=-b/2a
Then you calculate the axis for each equation:
1. y = x^2 + 2x
x1=-2/(2*1)=-1
2. y = x^2 − 16x + 58
x1=-(-16)/(2*1)=8
3. y = x^2 + 2
<em>notice: you don't have b term</em>
x1=-0/(2*1)=0
4. y = x ^2 − 4x + 2
x1=-(-4)/(2*1)=2
720 miles.
Going 60 miles per hour for 12 hours would amount to driving 720 miles in total.
Answer: The answer is 0.1076923 per dollar.
The set A = { 1,2,3,4,5,6,7,8,9}
<u><em>Step(i):-</em></u>
Given that the set
{ x/x/ is a natural number less than 10 }
<u><em>Natural numbers :</em></u>
The natural numbers are
{ 1,2,3,4,5,6,7,8,9,10,.........}
The set A = { x/x/ is a natural number less than 10 }
500 miles
81-11 is 70. 70 divided by .14 is 500 so that's 500 miles she can bike.
The correct option is A
The missing number is 34
By inspection, the third number is obtained by adding the two preceding numbers.
1 + 1 = 2
The next number is obtained by adding the two preceding numbers.
2 + 1 = 3
This continues as:
3 + 2 = 5
8 + 5 = 13
13 + 8 = 21
21 + 13 = 34
