I think number 9 is 8.34 x 10 with the exponent of -6
I think its thousend not sure tho
Answer:
6 ft
Step-by-step explanation:
10ft + 2ft = 12ft
12ft - 6ft = 6ft
She flies an additional 2ft so you add to 10ft which becomes 12ft. She goes down 6ft so you subtract from 12ft and get 6ft.
Answer:
y = 4
Step-by-step explanation:
Given that y varies jointly with x and z then the equation relating them is
y = kxz ← k is the constant of variation
To find k use the condition y = 16 when x = 4 and z =
, that is
16 = k × 4 ×
= 2k ( divide both sides by 2 )
8 = k
y = 8xz ← equation of variation
When x = 2 and z =
, then
y = 8 × 2 ×
= 16 ×
= 4
If x - 4 ≥ 0, then |x - 4| = x - 4, so
G(x) = F(x) ⇒ 3x + 2 = (x - 4) + 2
⇒ 3x + 2 = x - 2
⇒ 2x = -4
⇒ x = -2
Otherwise, if x - 4 < 0, then |x - 4| = -(x - 4), so
G(x) = F(x) ⇒ 3x + 2 = -(x - 4) + 2
⇒ 3x + 2 = -x + 6
⇒ 4x = 4
⇒ x = 1
However,
• when x = -2, we have
G(-2) = 3(-2) + 2 = -4
F(-2) = |-2 - 4| + 2 = 8
• when x = 1, we have
G(1) = 3(1) + 2 = 5
F(1) = |1 - 4| + 2 = 5
so only x = 1 is a solution to G(x) = F(x).
