4b + 22 = 5 (b + 4) - 1 (remove the parantheses)
4b + 22 = 5b + 20 - 1 (calculate)
4b + 22 = 5b + 19 (move the terms)
4b - 5b = 19 - 22 (collect like terms and calculate)
-b = -3 (change the signs)
<em>b = 3</em>

Hi
1.4 × 10³ × 2.5 × 10⁻⁶ = 1.4 × 2.5 × 10³ × 10⁻⁶ = 3.5 × 10⁻³
1.4 × 2.5 = 3.5
10³ × 10⁻⁶ = 10³⁻⁶ = 10⁻³
Answer: C) 3.5 × 10⁻³
Answer:
<em>a) the angle of ascent is 8.2°</em>
<em>b) the horizontal distance traveled is 4375 m</em>
Step-by-step explanation:
depth of ocean = 626 m
distance traveled in the ascent = 4420 m
This is an angle of elevation problem with
opposite side to the angle = 626 m
hypotenuse side = 4420 m
a) angle of ascent ∅ is gotten from
sin ∅ = opp/hyp = 626/4420
sin ∅ = 0.142
∅ = 0.142
∅ = <em>8.2° this is the angle of ascent of the submarine.</em>
b) The horizontal distance traveled will be gotten from Pythagoras theorem
= +
The horizontal distance traveled will be the adjacent side of the right angle triangle formed by these distances
= +
adj =
adj = <em>4375 m this is the horizontal distance traveled.</em>
I’m not sure but I think it is AC
