Answer:

Option A is correct.

Inverse operation of division is multiplication.

34 \times 3 = 102

Step-by-step explanation:

Verify the equation: 102 \div 3 = 34

Inverse operation of \div is \times

then;

102 \times \frac{1}{3} = 34

By cross multiply we get;

102 = 34 \times 3

therefore, the inverse operation would be used to verify the following equation is; 34 \times 3 = 102

An inelastic collision occurs between a large truck and smaller sedan. Calculate the final velocity of the objects and explain t
k0ka [10]

The final velocity is 15.8 m/s in the forward direction

Step-by-step explanation:

An inelastic collision occurs when the two object after the collision stick together.

In any case, the total momentum of the system is conserved before and after the collision, in absence of external forces. Therefore, we can write:

p_i = p_f\\m u + MU = (m+M)v

where in this problem:

m = 1300 kg is the mass of the small sedan

u = 20 m/s is the initial velocity of the small sedan

M = 7100 kg is the mass of the truck

U = 15 m/s is the initial velocity of the truck

v is the final combined velocity of the small sedan + truck

Here we have taken both the velocity of the sedan and the truck in the positive (forward) direction

Solving the equation for v, we find the final velocity:

v=\frac{mu+MU}{m+M}=\frac{(1300)(20)+(7100)(15)}{1300+7100}=15.8 m/s

And since the sign is positive, this means that is direction is the same as the initial direction of the sedan and the truck, so forward.

Solve the equation by finding square roots. To start, remember to isolate x^2. Equation= x^2+4=20
prohojiy [21]
Get the equation simplified. Subtract 4 by each side.
20-4= 16
and the square root of 16, is 4. 
Plug it in to check. 
(4)^2+4=20
16+4=20
20=20

Ultimately your final answer is X=4
