Answer:
x > 0
Step-by-step explanation:
The only thing that needs translation to symbols is "greater than". Your "word sentence" already uses the symbols x and 0. The symbol for greater than is >. Your inequality is ...

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

Step-by-step explanation:
Interest accrued is defined as the interest which we need to pay at the end of some time span. The interest accrued may be on daily basis as well as on monthly basis.
For calculating the interest accrued, we first multiply the principal amount with APR, this will give the interest of one year.
Then we will multiply it with the no. of months on which the interest is being calculated and divide it by total no. of months.
This will give the interest accrued every month.
When calculating interest accrued, you should <u>multiply the principal by the APR and number of months, then divide by the total number of months in the year.</u>
