Answer: C
<u>Step-by-step explanation:</u>
Let x represent the first term (a₁)
a₁ = x
a₂ = x(-√2) = -x√2
a₃ = -x√2(-√2) = 2x
a₄ = 2x(-√2) = -2x√2
a₅ = -2x√2(-√2) = 4x
Since it is given the a₅ = √2, then we can solve: 4x =√2
Divide both sides by 4 to get: x = 
this can also be written as: 
Answer:
the answer is 12x +3
Step-by-step explanation:
To find where on the hill the canonball lands
So 0.15x = 2 + 0.12x - 0.002x^2
Taking the LHS expression to the right and rearranging we have -0.002x^2 + 0.12x -
0.15x + 2 = 0.
So we have -0.002x^2 - 0.03x + 2 = 0
I'll multiply through by -1 so we have
0.002x^2 + 0.03x -2 = 0.
This is a quadratic eqn with two solutions x1 = 25 and x2 = -40 since x cannot be negative x = 25. The second solution y = 0.15 * 25 = 3.75
Answer:
One solution x = 2
Step-by-step explanation:
Given the equation:

Multiply this equation by 2:

Use distributive property:

Combine the like terms:

Thus, this equation has one solution x = 2
