Answer:
Step-by-step explanation:
Please use " ^ " to indicate exponentation: y= x^2 + 11x + 24. Thanks.
Because x^2 is positive, the graph of this parabola opens up.
We can find the vertex and roots (zeros) as follows, using the quadratic formula:
With a = 1, b = 11 and c = 24,
-11 ± √ [ (11^2-4(1)(24) ] -11 ± √25
x = ------------------------------------ = --------------- = -3 and x = -8
2(1) 2
This tells us that the x-intercepts are at (-3, 0) and (-8, 0). The minimum value is at x = -b / (2a), which here is x = -11 / [2] = -5 1/2 (which is halfway between the zeros).
The vertex (and thus, the minimum) is at (-5 1/2, f(-5 1/2) ).
Answer: The average is 22
Step-by-step explanation: To calculate any average from a database like this one, add all the numbers to find your total, which in this case would be 132. Then divide the total by however many numeric values you had to add, which would be 6. This gives you your final equation, (132 divided by 6 = 22).
Answer
false
Step-by-step explanation:
False; h could be anything. For example, it could be pi, which is irriational.
Answer:
x = 23°
Step-by-step explanation:
90 = 3x - 9 + x + 7
90 = 4x - 2
92 = 4x
x = 23°

3/x=15/40
solve for x
multiply both sides by x
3=15x/40
multiply both sides by 40
120=15x
dvide both sdies by 15
8=x
the answer is 8
or you could simplifyy 15/40 to get 3/8
