Answer:
40/41
Step-by-step explanation:
tanB=opposite length/adjacent length
tanB=40/41
Answer:
Step-by-step explanation:
- 2· + 20 = 32
- 2· = 12
- = 6
- (v + 4) log 4 = log 6
- v + 4 = log 6 / log 4
- v + 4 = 1.29 (<em>rounded</em>)
- v = 1.29 - 4
- v = - 2.71
The correct option regarding the system of equations is given as follows:
B. The solution is nonviable because the time cannot be negative.
<h3>What is a system of equations?</h3>
A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
The systems use linear equations, and the solution is the intersection of the lines. In this problem, the curves intersect at (-4,0), that is, they have the same percentage at a time of -4 seconds, which is nonviable, as the time cannot be negative, hence option B is correct.
