The pay, P, at a certain job is calculated by the formula P=Bh, where B is the base pay an h is the number of hours worked. If an employee works more than40 hours in a week, the formula changes to P=40B+1.5B(h-40). If Susan had a base pay of $6.35 and worked 28 hours, what would be his pay for the week?

Answers

If you would like to know the Susan's pay for the week, you can calculate this using the following steps:

P = B * h
P ... the pay
B ... the base pay
h ... the number of hours worked

B = $6.35
h = 28 hours
P = B * h = $6.35 * 28 hours = $177.8

Susan's pay for the week would be $177.8.

Which equation can be used to model simple harmonic motion? A. d=acos[w(t+k)] B. d=acos(wt) C. d=asin(wt)+k D. d=sin(awt)

Answers

B. d=acos(wt)
Hope it helps

Answer:

Correct option is B.

Step-by-step explanation:

Given some equations we have to choose the equation which can be used to model simple harmonic motion.

The basic equation for simple harmonic motion are

x = acos(wt)  and x=asin(wt)

where x is displacement from resting position,  

a is the amplitude, which is the largest displacement the object experienced, w is the angular velocity or angular frequency and t is the time.

From the given options B option matches i.e

d=acos(wt)

is the equation can be used to model simple harmonic motion.

So, correct option is B.

How do I solve a quadratic equation like this: x squared minus 9x = -14?

Answers

x^2-9x=-14\n\nx^2-9x+14=0\n--------------------\n-9=-7+(-2)\n14=-7\cdot(-2)\n--------------------\n\nx^2-9x+14=(x-7)(x-2)\n\n(x-7)(x-2)=0\iff x-7=0\ or\ x-2=0\n\nx=7\ or\ x=2



x^2-9x+14=0\n\na=1;\ b=-9;\ c=14\n\n\Delta=b^2-4ac\n\n\Delta=(-9)^2-4\cdot1\cdot14=81-56=25\n\nx_1=(-b-\sqrt\Delta)/(2a)\to x_1=(9-√(25))/(2\cdot1)=(9-5)/(2)=(4)/(2)=2\n\nx_2=(-b+\sqrt\Delta)/(2a)\to x_2=(9+√(25))/(2\cdot1)=(9+5)/(2)=(14)/(2)=7
Bring everything over to one side.
    x² -9x=-14
x²-9x+14=0
Now it is an easy trinomial so you need to find two numbers that add up to -9 and multiply to equal 14. The two numbers are -7 and -2. 
 x²-9x+14=0
 (x-7)(x-2)=0
            x= 7 and 2
