5x+20+16
the expression is 5x+36
Answer:
y = 4 sin( 0.5t - ) - 2
y = a sin ( 2t - ) + 2
Step-by-step explanation:
In the first question,
amplitude = 4
Period =
phase shift =
Vertical shift = -2
Angular velocity , w =
Here, w = = 0.5
The general equation of a wave is
y = a sin( wt + ∅ )
Putting above values in the equation,
y = 4 sin( 0.5t - ) - 2
In the second question,
Amplitude is not given so we will take it as a.
time period =
w = 2
Phase shift =
Vertical shift = 2
The equation is
y = a sin ( 2t - ) + 2
Explanation:
The equation is already in standard form.
A is 1. The number 1 is often unwritten.
B is -3. The negative or positive sign is included with the equation.
C is -6. (If using this for the quadratic formula, c is actually 6 because the equation should equate to 0).
Answer:
You will have to sell $7,667 worth of sales in a week in order for the straight commission offer to be at least as good
Step-by-step explanation:
Step 1: Get the total straight commission offer
We can express the straight total commission as follows;
A=R×T
where;
A=straight total commission
R=commission rate
T=total sales
In our case;
R=5%=5/100=0.05
T=t
replacing
A=0.05×t=0.05 t....equation 1
Step 2: Total amount of the second offer
We can express the total amount of the second offer as follows;
A=F+(R×T)
where;
A=amount of income the second company offers
F=fixed salary per week
R=commission rate
T=total sales
In our case;
F=$230 per week
R=2%=2/100=0.02
T=t
replacing;
A=230+(0.02×t)=0.02 t+230....equation 2
Step 3: Equate equation 1 and 2
0.05 t=0.02 t+230
(0.05 t-0.02 t)=230
0.03 t=230
t=230/0.03
t=7,666.67 rounded up=7,667
You will have to sell $7,667 worth of sales in a week in order for the straight commission offer to be at least as good
Because the 0 is not necessary. Usually the 0 is taken out and it would be written as 7.63. <span />
