Answer: Choice C</h3>
==================================================
Explanation:
We can rewrite the exponent 9.969 as 9 + 0.9 + 0.06 + 0.009
Then convert each decimal to a fraction
- 0.9 = 9/10
- 0.06 = 6/100
- 0.009 = 9/1000
Your teacher is choosing not to reduce any of these fractions.
Then you'll use this rule to break up the exponent into the pieces mentioned.
So,

Answer:
p = 11.2
Step-by-step explanation:
2.6(5.5p – 12.4) = 127.92,
5.5p - 12.4 = 49.2,
5.5p = 61.6,
p = 11.2
The x value of the vertex in
ax^2+bx+c is -b/2a
y value is just sub for x
3x^2-6x+5
x value of vertex is -(-6)/(2*3)=6/6=1
sub back
y=3(1)^2-6(1)+5
y=3(1)-6+5
y=3-1
y=2
vertex is (1,2)
