The graph of f(x) = ax2 opens upward and is narrower than the graph of f(x) = x2. Which of the following could be the value of a? a)-6
b)-0.7
c)0.4
d)3

answer: your correct answer is b. d.

step-by-step explanation:

where is the diagram? shown below where? ?

step-by-step explanation:

answer:   (s+1)(s+4)

step-by-step explanation:

factor s2+5s+4

s2+5s+4

=(s+1)(s+4)

perimeter = 10 +  √10  units

explanation:

first, we will need to get the length of each line using the distance formula which is as follows:

distance = 

1- length of ab:

ab =   = 5 units

2- length of ac

length of ac is the same as ab = 5 units

3- length of bc:

bc =   =  √10  units

now, we can get the perimeter by adding the side lengths as follows:

perimeter = 5 + 5 +  √10

perimeter = 10 +  √10  units

hope this : )
