Answer:
The correct answer is d Both the observer's are correct
Explanation:
We know by postulates of relativity that laws of physics are same in different inertial frames.
Thus for each of the frames they make observations related to their frames and since the observations are true for their individual frames they both are correct. But when we compare the two frames we need to use transformation equations to compare both the results.

Answer:
The marginal revenue is positive when Roland sells 144 driers per week ( D
Explanation:
Elasticity of demand = -0.463
P = $127
116 hair dryers sold per week ( q )
demand function is differentiable
<u>prove the true statement below</u>
Revenue = price per unit * quantity
determine the Marginal revenue = dr / dq
∴ MR = P + q dp/dq
price elasticity of demand E(p) = - dq / dp * p/q
where : E ( p ) = - 0.463 , q = 116 , p = $127
q * dp/dq = P / 0.463
∴ MR = P * 1.463 / 0.463
= 127 * 3.16 = $401.32
since the Marginal revenue > 0 HENCE The marginal revenue will be positive when Roland sells 144 driers per week.
<span>m^(- 5) = 1/35 → you know that: x^(- a) = 1/x^(+ a) = 1/x^a
1/m^5 = 1/35 → you take the inverse
m^5 = 35
[m^5]^(1/5) = 35^(1/5) → recall: (x^a)^b = x^(ab)
m^[5 * (1/5)] = 35^(1/5)
m^[1)] = 35^(1/5)
m = 35^(1/5)
The scientific notation is a number between 1 and 9 with few numbers after coma (point) completed by a power 10.
= [1.4 * 10^(3)] * [2.5 * 10^(- 6)] → you remove the brackets
= 1.4 * 10^(3) * 2.5 * 10^(- 6) → you order
= 1.4 * 2.5 * 10^(3) * 10^(- 6) → you make the multiplication
= 3.5 * 10^(3) * 10^(- 6) → recall: (x^a) * (x^b) = x^(a + b)
= 3.5 * 10^(3 - 6)
= 3.5 * 10^(- 3) ← answer C</span><span>
