Y=-x²+12
This is a parabola opening downward because the coefficient of x² =1 >0
The domain (the value of the input of x) is all real numbers.
to find some points (& you can extend to 1,000,000 points) that are on the graph, replace x by any value & you'll find the related value of y
Example:
f(1)= 1²+12 = 13 ==> for x=1 y=13 & this points ∈ to the parabolas
f(2) = 2²+12 =16 ===> for x=2, y=16) this points ∈ to the parabolas
and so on & so forth
Answer: 60
Step-by-step explanation:
180 degrees because of the line so 180-120 = 60
<span>434.657, hundredth digit is 5, after the 5 is 7, since the 7 is more than 5, we add 1 to the hundredth digit 5, to make it become 6.
</span>434.657 ≈ 434.66 to the nearest hundreth.
102.494, hundredth digit is 9, after the 9 is 4, since the 4 is less than 5, we the hundredth digit remains as 9.
102.494 <span>≈ 102.49 </span>to the nearest hundreth.
Hope this helps.
Answer: 7 cm
Step-by-step explanation:
We know that, Triangle's area= 0.5 × Base × Height
So,
28 = 0.5 × 8 × Height
⇒Height= {28/(0.5 ×8)} = 7 cm
