Answer:
Step-by-step explanation:
Start with where it tells you the value of x. The value of x is 3. That's given by f(x) = f(3)
Next see which one of the functions you use. x > 0 is given by x^4 - 7. Since 3 is greater than zero you use x^4 - 7
f(3) means that wherever you see an x on the right side, you put a 3.
f(x) = x^4 - 7
f(3) = 3^4 - 7
f(3) = 81 - 7
f(3) = 74
Answer:
The answer is 66.5
Step-by-step explanation:
To get the mean, you add all the numbers together, then you divide by the # of numbers their are. So you add 34,56,78,98, and then you divide by 4.
Answer:
x = 9.7
Step-by-step explanation:
The area of a triangle is A = b * h / 2 where A, b, and h are the area, base and height respectively. We know that A, b, and h equal 47, x, and x respectively so we can write:
47 = x * x / 2
47 = x² / 2
94 = x²
x = ±√94
In context, x can't be negative so the answer is x = √94 = 9.7.
Answer:
y 0.4
x 0.3
Step-by-step explanation:
Answer: $4850
Step-by-step explanation:
The other information related to the question is:
Direct materials = $3.50
Direct labor = $1.10
Variable overhead = $0.45
Fixed overhead = $2.80
Total = $7.85
Based on the information given in the question, the increase in the profit will be calculated as the contribution from the 3000 extra units minus the worker's salary.
Contribution from 3000 units will be:
= (Selling price - Direct materials - Direct labor - Variable overhead) × 3000
= ($25 - $3.50 - $1.10 - $0.45) × 3000
= $19.95 × 3000
= $59850
Increase on Profit:
= $59850 - $55000
= $4850
