Answer:Therefore, f(−1)=6.
Step-by-step explanation:
So, if f(x)=x+7 then f(−1)=(−1)+7
Therefore, f(−1)=6.
Answer:
Step-by-step explanation:
In order to solve this quadratic, we have many methods. We can factor, complete the square, or use the quadratic formula. I'm going to factor since it's the easiest method.
To factor, find two numbers that when multiplied equal a(c) and when added equal b.
a=1, b=-4, and c=-5.
So we want two numbers that when multiplied equals 1(-5)=-5 and when added equals -4.
-5 and 1 are the possible numbers. Therefore:
Step-by-step explanation:
Given diameter (d) = 28 inches
π = 3.14
Radius (r) = 28/2= 14 inches
Now
Area of the circle
= πr²
= 3.14 * 14²
= 615.44 inch ²
Answer:
Salaried pay. Salaried employees make more per week than hourly employees.
Step-by-step explanation:
A salaried employee makes $67,000 per year. To know which option is better, we need to calculate how much hourly employees make in year.
An hourly employee needs to work 44 hours a week (0+10+8+8+7+6.5+4.5 = 40). So the first 40 hours will be paid 25$ per hour and the next 4 will be paid $37.50 per hour. So an hourly employee will make $1150 a week (40*$25 + 4*$37.50 = $1150).
Considering that a month has 4 weeks, and a year has 12 months, an hourly employee will make $55,200 a year ($1150*4*12=$55,200).
An hourly employee makes $55,200 a year, while a salaried employee makes $67,000. So I would recommend the option c) to a new employee.
Answer:
