What is the meaning of the t-intercept of the altitude graph? The y-intercept?
Gnom [1K]

Answer: Hello mate!

We know that you have a graph of y vs t, and we know that this is an "altitude" graph.

Then we can assume that the y represents the altitude, and t represents the time, and this graph shows the altitude of something as a function of the time.

the t-intercept means that the graph passes through the y-axis, this means that, in this point, y is equal to zero:

Then, at the t-intercept, we have y = 0, which means that at this time (where is the intersection) the altitude is equal to zero.

The y-intercept means that the graph passes through the y-axis, where t = 0

this is the initial value of the altitude, where t = 0 usually denotes the time where we start to measure.

I need help. Work has to be shown but i don’t know how to do them
mote1985 [20]

Step-by-step explanation:

1.

1% of 500 is 5 so multiply 5 by 8 for one year. which is 40 so multiply that by 2.

1% of 500 = 5

5 × 8 = 40

40 × 2 = 80

2.

1% of 1000 = 10

10 × 5 = 50

50 × 3 = 150

3.

12 months = 6%

6/12 = 1 month

0.5 = 1 month

0.5 × 9 = 4.5 (the amount of interest for 9 months.)

800 × 4.5% = 36

4.

12 months = 7%

7/12 = 1 month ( i'll leave this in fraction form because of the decimal points.)

7/12 x 8 = 4.666667 or 4.7 rounded.

1200 × 4.7% = 56.40
