where vertex (h,k) p is the distance from vertex to focus
Answer: 10
Step-by-step explanation:
45x = 180
divide by 45
x=4
yes
420 /d = 30
multiply by d
420 =30d
divide by 30
14 =d
no d=14
37+s = 80/2
37+s =40
subtract 37 from each side
s =3
no s=3
52+g =45+11
52+g = 56
subtract 52 from each side
g=4
no g=4
13+14 = 3f
27 = 3f
divide by 3
9=f
yes f=9
Answer:
x = 70.71
Step-by-step explanation:
log 2x² + 2 = 6.
log 2x² + log 100= log 10⁶.
2x² × 100 = 10⁶
2x² = 10⁶/100
2x² = 10⁴
x² = 10⁴/2
x² = 5000
x = √5000
x is approximately 70.71
x = 70.71
