Answer:
The temperature will be at 40 degrees by 7:00
Answer: h(3.2) =753.44 units represents the height after 3.2 seconds .
Step-by-step explanation:
Since we have given that the function

where t represents the time in seconds .
And we need to find the value of h(3.2)
So,
we just substitute the value of 3.2 in the function,

So, after 3.2 seconds the height will be 753.44 units.
280 = 7 x 2^3 x 5
882 = 7^2 x 2 x 3^2
For 280k to be perfect square , their powers need to be even
For 882 to be a cube, their powers need to be in multiple of 3,
To satisfy both parties,
K = 7 x 2^5 x 3^4 x 5^3 = 2268000
A rational number stops and can be turned into a fraction and doesn’t repeat while an irrational number does the opposite
