The function has a maximum at (1, 3).
_____
You know it is not a minimum because the coefficient of the squared term is negative.
You know the vertex is (1, 3) because you match the pattern to
.. y = a(x -h)^2 +k
which has its vertex at (h, k).
2x+8–10=22
2x=24
x=24/2
x=12
yes! you’re absolutely right, i hope i helped you
Answer:
18m
Step-by-step explanation:
Since the given traingles are similar
We get
Hence the distance across river is 18m

Hello :
y² =x^3+3x²
the derivate is : 2yy' = 3x²+6x
where x= 1 and y = 2
2(2)y' = 3(1)²+6(1)
4y' = 9
y' = 9/4
an equation at (1.2) is : y = (9/4)(x-1)+2
y= (9/4)x-1/4
