Answer:
35
Step-by-step explanation:
1kg= 1000g
1 hectare = 10 000 m²
1 kg/hct = 1000/10 000 g/m²
1 kg/hct = 1 / 10 g/m²
350 kg per hectare is equal to 350 / 10 = 35 g/m²
The x-intercept will be the value of x when y=0. The solutions to (x+1)(x+2)=0 are -1 and -2 since we can substitute them in to have one of the values in parentheses equal to zero, so our x-intercepts are (-1, 0) and (-2, 0). The y-intercept is the value of y when x=0, or (0+1)(0+2)=2. Therefore, the y-intercept is (0, 2).
Ways to spot if an expression is not a polynomial:
1) If there is a negative exponent
2) If there is division by a variable
3) If the power is something other than a non-negative integer
If any of these conditions exist, the expression will not be a polynomial. Now consider the options. Option A has negative exponent, Option B involves division by a variable and Option D has a exponent which is not a number.
So, from the given options, option C is the only polynomial
It would be 1. You add all the temperatures. Get the sum and divide it by the amount of temperatures.
B is just simply the y intercept
