Round to the nearest whole number.<br> 432.846
Gelneren [198K]

Answer: 433 of course

432 is the whole number and 846 is the decimal,

the number closest to the whole number is 8

we can only round the number forward if the number is 5 or more than 5 (6,7,8,9)

so 432.856 rounds to 433

Anybody good in math ?
swat32

Answer:

y=-0.3(x-2)^2+2

Step-by-step explanation:

We know that the parabola faces downard, and hence must have a negative first term, so that eliminates the first and third options.

The vertex of the parabola has an x-value of 2, so it must be of the form a(x-3)^2+c.

Combining these, we have that the answer is \boxed{y=-0.3(x-2)^2+2}
