Answer:
y = sin(x + 90)
Step-by-step explanation:
If you graph the sine function and then translate the entire graph 90 degrees to the left, you obtain the cosine function, which is shown in this graph.
The first answer option is the correct one.

Answer:
Option B
Step-by-step explanation:
we know that
<u>SAS Similarity Theorem</u>: If two sides in one triangle are proportional to two sides in another triangle and the included angle in both are congruent, then the two triangles are similar.
In this problem
∠STR is congruent with ∠QTP
Verify if the corresponding sides are proportional
----> is true
therefore
The triangles TRS and TPQ are similar by SAS
Answer:
- Starting profit was twice the cost price or 2/3 of the selling price
Step-by-step explanation:
<u>Selling price is:</u>
<u>Then, profit:</u>
<u>Let profit be x, then</u>:
- x = SP - CP initial profit
- 7x = 5SP - CP new profit
- 6x = 4SP subtracting the above 2 equations
- x = 4/6SP
- x = 2/3SP profit in terms of selling price
<u>Finding profit relationship with cost:</u>
- CP = SP - 2/3SP = 1/3SP
- SP = 3CP
- x = 2CP profit in terms of cost
Starting profit was twice the cost price or 2/3 of the selling price
