Answer: 1/1000
Step-by-step explanation:
Answer:
the first one
Step-by-step explanation:
Answer:
y =x^2 +8x +15
factories form
y =( x+5 )( x+3 )
x intercept where the graph meet the x axis
y = x^2 +8x +15
let y =0
0 = x^2 +8x +15
0 = ( x + 5) (x+3)
o = x+5 or 0 = x+3
-5 = x or x = - 3
x intercept
(-5;0)
(-3 ;0)
axis of symmetry : where you will cut the graph into two half
x = - b/2a
x = - 8/2(1)
x = - 8/2
x = - 4

Answer:
7) p=80
8)z= 19.2
Step-by-step explanation:
7th problem)
0.1p=8
p * 
=8
=8
p=80
8th problem)
=8
z=8*2.4
z=19.2
