Answer: 12 pounds.
Step-by-step explanation:
To solve this question, we'll use the direct proportion which is.
y = kx
Where,
y = weight on moon = 48 pounds
x = weight on Earth = 300 pounds
k = Unknown
y = kx
48 = 300k
k = 48/300
k = 0.16
The weight that a 75 pound object on Earth would weigh on the moon will be:
y = kx
where,
y = weight on moon = Unknown
k = 0.16
x = weight on Earth = 75 pounds
y = kx
y= 0.16 × 75
y = 12 pounds
The weight on the moon will be 12 pounds.
Let f(x) be the real value function. Remember that:
→ Even: f(x) = f(-x) → Odd: -f(x) = f(-x)
If -f(x), then -f(x) = -x³ + 5x If x = -x, then f(-x) = -x³ + 5x
Since -f(x) = f(x), the function is therefore odd.
Answer:
7
Step-by-step explanation:
Note that
(g - 
)² = g² - 2 + 
= 51 - 2 = 49
Take the square root of both sides
g - = 
= 7 ← the positive value
