Classify the sequences as arithmetic geometric, Fibonacci -5,0,10,15,25
vovikov84 [41]

It is arithmetic.

It starts at - 5,

the next item is 0 then 5 and next is 15 ...

============

It isn't geometric. You  are not  multiplying by 5

The second term  must be and not- 5 * 5 = - 25

============

A Fibonacci series adds the previous two terms together to get the next term

Usually it starts at 0, but it doesn't need to.

0,1,1,2,3,5,8,13,21,34 ....

Task 1:
OleMash [197]

Answer:

maximum height is 4.058 metres

Time in air = 0.033 second

Step-by-step explanation:

Given that the equation height h

h = -212t^2 + 7t + 4

What is the toy's maximum height?

Let us assume that the equation is a perfect parabola

Time t at Maximum height will be

t = -b/2a

Where b = 7 and a = - 212

t = -7/ - 212 ×2

t = 7/ 424 = 0.0165s

Substitute t in the main equation

h = - 212(7/424)^2 + 7(7/424) + 4

h = - 0.05778 + 0.115567 + 4

h = 4.058 metres

Therefore the maximum height is 4.058 metres

How long is the toy in the air?​

The object will go up and return to the ground.

At ground level, h = 0

-212t^2 + 7t + 4 = 0

212t^2 - 7t - 4 = 0

You can factorize the above equation and pick the positive time t since time can't be negative

Or

Since we have assumed that it's a perfect parabola,

Total time in air = (-b/2a) × 2

Time in air = 0.0165 × 2 = 0.033 s
