To find the minimum value of function 1, we need to find the vertex. The formula for the x-coordinate of the vertex is -b/2a, which is -1 in this equation. However, to find minimum and maximum values, we need to look at the y-coordinate. f(-1) is 4, which we know is a minimum (rather than a maximum), because the leading coefficient is positive -- so the parabola opens upwards. So, the minimum value of f(x) is 4, and the coordinate is (-1, 4).
From the table, the minimum value of g(x) is 3, and the coordinate is (0, 3).
Therefore, function 2 has the lowest minimum value, with coordinates (0, 3).
V = 25,364.4 cm^3 Is volume
r = 2.7g/cm^3 Is density
To calculate mass you use formula:
m= V*r
To avoid remembering this formula you can see the type of unit on each given variable. We can see that we have g/cm^3 and cm^3. If we multiply them, we negate cm^3 and cm^3 and we are left with g which is unit for mass.
m = 68,486,6 g is the answer.
The answer is the last one option: y+6=-34(x+2). I told you the reason in the other similar question.
Add 1 to both sides and then split the parentheses to (x+3) and (x+3) then multiply them to get x^2+6x+9=36
To find the total snow fall you would multiply the amount of snow per hour by the number of hours it snows:
Total = 3/4 inch per hour x hours: Total = 3/4h
h = 12 hours:
Total = 3/4(12) = 9 inches total.
