First, we want to solve for b.
In order to solve for b, we plug in x=6 and f(x)=7 into the equation, since we know f(6)=7
7 = (3/2)(6) + b
7 = 9 + b
Subtract both sides by 9
b = -2
Now, let's insert this value into the equation
f(x) = (3/2)x - 2
Now, plug in x = -2 into the equation to calculate f(-2)
f(-2) = (3/2)(-2) - 2
= -3 -2
= -5
Thus, your answer is A.
Have an awesome day! :)
Answer:
an emt is an ambulance worker
Explanation: the ambulance saves lives they are a little less taught than a doctor
A) The x-component of the shot's acceleration while in flight is; aₓ = 0 m/s²
B) The y-component of the shot's acceleration while in flight is;
a_y = -9.8 m/s²
C) The x-component of the shot's velocity while in flight is; vₓ = 7.55 m/s
D) The y-component of the shot's velocity while in flight is;
a_y = 9.32 m/s
<h3>Projectile motion</h3>
A) The x-component of the shot's acceleration while in flight?
aₓ = 0 m/s²
B) Since the object is thrown vertically, it means that it is against gravity and as such acceleration due to gravity will be negative,
Thus, the y-component of the shot's acceleration while in flight is;
a_y = -9.8 m/s²
C) The x-component of the shot's velocity at the beginning of its trajectory is; v_x = v cos θ
v_x = 12 cos 51
v_x = 7.55 m/s
D) The y-component of the shot's velocity at the beginning of its trajectory is; v_y = v sin θ
v_y = 12 sin 51
v_y = 9.32 m/s

18 boxes of nails weighs 49.5 kg
So one box weighs 49.5/18=2.75 kg
Therefore each box weighs 2.75 kg
That means each box weighs 2 wholes and 3 by 4
