Answer: no solution or zero solutions.
Step-by-step explanation:
(-5x^5)(a) = 25x^7 + 100x^5
<u>+5x^5 +5x^5</u>
a = 25x^7
Answer:
Simplifying
5x + x = 54
Combine like terms: 5x + x = 6x
6x = 54
Solving
6x = 54
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Divide each side by '6'.
x = 9
Simplifying
x = 9
Step-by-step explanation:
The Z-score (z) is calculated according to the formula: z = (x - μ) / σ
Where: x is the raw score value, μ is the mean of the population, σ is the standard deviation of the population.
x = 80, μ = 5, σ = 4
z = (80 - 5) / 4
z = 75 / 4 = 18.7500
Z-score is 18.7500
Answer:
The answer is (d) ⇒ e = 1/7 , k = 12 , conic ellipse
Step-by-step explanation:
∵ r = ek/(1 ± ecosФ)
∵ r = 12/(7 - cosФ) ⇒ ÷ 7 up and down
∴ r = 12/7 ÷ 1 - 1/7 (cosФ)
∴ e = 1/7
∵ 12/7 = ke ⇒ 12/7 = k(1/7)
∴ k = 12
∵ 0 < e < 1
∴ The conic is ellipse
