2,2.5

Answer: Between <u>2</u> and <u>2.5</u> seconds

How am I getting those values? Those values are selected from the 't' column on the left side of the table. These are time values in seconds. Note how t = 2 corresponds to h = 0.4; while t = 2.5 corresponds to h = -10.6

The change in sign for the height, from positive to negative, means that the height h must be zero at some point between t = 2 seconds and t = 2.5 seconds. We don't know where exactly, but we know that h = 0 at least once in this interval. This is because the height is a continuous function. There are no jumps or gaps in the height (the object can't teleport or anything)

Answer:

3

Step-by-step explanation:

j(2) means that x equals 2...

the first inequality in the function says that x is greater than or equal to 2

the second inequality states that x is greater than 2(not equal to) and is less than or equal to 5

the third one states that x is greater than 5

x applies to the first inequality since we know that x can be equal to 2

Now, to the number before the if

there is a 3 before the if in the first inequality

This means that if x is greater than or equal to 2 the y or the function would equal 3

therefore, j(2) would equal 3

I hope this helps!!!

If f(1) =7 and f(n)=-5f(n-1)-n<br><br> then find the value of <br> f(4)
jolli1 [7]

Answer:

-914

Step-by-step explanation:

f(n)=-5f(n-1)-n

f(2)= -5f(1) -2 = -5(7) - 2 = -37

f(3) = -5f(2) - 3 = -5(-37) - 3 = 182

f(4) = -5f(3) - 4 = -5(182) - 4 = -914
