Answer:
y = 2x^2 +1
Step-by-step explanation:
This is a parabola so it is in the form
y = a( x-h) ^2 + k
where ( h,k) is the vertex which is at ( 0,1)
y = a (x - 0)^2 + 1
y = ax^2 +1
Pick another point on the graph to determine a
(1,3)
3 = a(1)^2 +1
Subtract 1 from each side
3-1 = a(1)
2 =a
y = 2x^2 +1
Answer:
0.88
Step-by-step explanation:
You first multiply the fraction by 11 which is 88/99. Then, from common knowledge, you'll know that anything over 99 is repeating itself so it is 0.88 repeating.
Find the value of any expressions (within) parentheses first. Then evaluate all powers. Then multiply or (divide) from left to right, and finally add or (subtract) from left to right.
Answer:
71
Step-by-step explanation:
in a triangle all the angles together equal 180°. So all you have to do is add 43 + 66=109 and then subtract that from 180
