Answer:
f(3) = -20
Step-by-step explanation:
To find the value of a function, substitute the number for the variable and do the arithmetic.
f(x) = -2x^2 +x -5 . . . . . . given
f(3) = -2(3^2) +(3) -5 . . . . function value for x = 3
f(3) = -2(9) +3 -5 = -18 +3 -5
f(3) = -20
The apothem of this is 13
You can write it as:
-4≥x≤6
*The '≥' and '≤' just means that it is greater than or less than but it can still be equal to the number you are comparing it to.
Hope this helps! :)
Answer:
¾
Step-by-step explanation:
More than 3: 9
P(more than 3) = 9/12 = ¾
Prism volume = lbh
= 10*8*12
= 960cm^3
Note: I'm assuming the hole was cut right through it...
Hole volume = lbh
= 2*3*12
= 72cm^3
Final volume = 960 - 72 = 888cm^3
