I think it is D
Just the test, D and E are correct:
f(x)= 5(
)
f(x)= 5(5)
Answer:
Step-by-step explanation:
y=ax²+bx+c
x=0,y=0,c=0
y=ax²+bx
2=9a+3b (×-5)
3=25a+5b(×3)
add
9-10=75a-45a+15b-15b
30a=-1
a=-1/(30)
2=9×(-1/30)+3b
3b=2+3/10=23/10
b=23/30
y=-1/30 x²+23/30=-1/30(x²+23x+(23/2)²)+1/30 ×(529/4)
y=-1/30(x+23/2)²+529/120
Solution
What is the range of possible lengths, x, of this triangle?
Step-by-step explanation:
12 cm + 18 cm = 30 cm
18 cm - 12 cm = 6cm
The possible measures of the third side are any length between 6 cm and 30 cm
[tex]6cmHence the answer is
