Answer:
4) 1400 
5) 304
or 954.56
6) 315 
Step-by-step explanation:
<span>What is the axis of symmetry for f(x)=5(x+7)(x-5)? Multiply out this polynomial to obtain the equation of a parabola in the form y = ax^2 + bx + c.
f(x) = 5(x^2 - 5x + 7x -35)
Holding the coefficient 5, we have 1x^2 - 2x - 35. Here a = 1 and b = -2, and
thus x = -b / (2a) provides the x-coord. of the axis of symm. It is:
x = -(-2) / (2*1) = 1.
The axis of symmetry is the vertical line x = 1.</span>
Answer: $ 436.81
Step-by-step explanation:
Given: Hourly rate for Peggy= $7.50
Also, she receives 9% of the gratuities earned by all the staff.
Total hours she worked = 35 hours
Total gratuities = $1936.80
Gross pay = (Hourly rate ) x (Number of hours worked)+ 9% of (Total gratuities )
= $ [(7.50 ×35)+(0.09 ×1936.80)]
= $ (262.5 +174.31)
= $ 436.81
Hence, her gross pay = $436.81
2 = 25%. 25% also means 1/4. So, it is a quarter of something. So. So find 100%, you have to multiply 2 by 4. 2 * 4 = 8. Roman has 8 pencils in his backpack.
