Answer:
The relation between battery capacity and time is:
The graph is attached.
Step-by-step explanation:
We will graph the charged capacity of the battery in function of time.
The rate of charge is constant, so we can conclude the relation is linear.
At time t=0, the battery capacity is at 0.2 (or 20%).
Every minute that passes, an additional 5% percent of its capacity is charged. So we can say that at t=1, the battery capacity is 0.2+0.05=0.25 (or 25%).
We can calculate the slope of the linear function as:
Then, the relation between battery capacity and time is:
Answer:
The angles are: 25°, 25°, 155° and 155°.
Step-by-step explanation:
1. By definition, the intersection of two lines forms four angles. Each opposite pairs of them are known as "Vertical angles" and they are congruent, which means than they have the same measure.
2. The sum of the four angles is 360°.
3. If the sum of the two angles is 50°, you can calculate the measure of each one of them by dividing 50° by 2:
4. To find each measure of the other two angles, you must subtract 360° and 50° and divide this by 2:
