Answer:
Step-by-step explanation:
f(x) = -2(x − 4^)2+ 2
The vertex is (4,2)
so the axis of symmetry is is x=4
g(x) = 5x^2− 10x + 7
h= -b/2a = 10/2(5) = 10/10 =1
The axis of symmetry is at x=1
h(x) the axis of symmetry is at x=-2
Bar graphs sorry if I’m not right
Answer:
3.6
Step-by-step explanation:
Pythagorean theorem:
a^2 + b^2 = c^2
(6 km)^2 + b^2 = (7 km)^2
36 + b^2 = 49
b^2 = 13
b = sqrt(13)
b = 3.6
Answer: 3.6 km
If its diameter is 443 square inches, then its circumference is:
443 π square inches, as C=πd.
Answer:
18 and 65
Step-by-step explanation:
under 18 would be 17 and under, therefore not including 18 year olds. obviously they are not 19 yet either, so they wouldn't fall into either category, therefore they may be unsure of what to answer.
same with 65 year olds; they are more than 64 year old, but not yet /over/ 65, therefore they would not fit into either category either.
