Well the formula for the quadratic equation is y = -b + √b² - 4ac / 2a
Fill in the variables with the information where a = 2, b = 2, and c = -12.

The final answer is y = -2 + √2² - 4(2)(-12) / 2(2)
A simplified answer would be y = -2 + √4 + 96 / 4, which further simplifies to
y = -2 + 10 / 4

This can be simplified into two answers, either y = -3 or y = 2

Step-by-step explanation:

X interprets (0,0), (-5, 0) all you must do is divide 5 by 2 so 5÷2=2.5 that is your answer

Lim (sin(pi/x)) as x tends to 0 from both sides

strojnjashka [21]

Hello from MrBillDoesMath!

Answer:

Limit does not exist.

Discussion:

The function 1/x has a vertical asymptote as x approaches 0 so

sin (pi/x) has no limit as x approaches 0. In fact, it oscillates wildly between -1 and 1 as x approaches 0. See attached graph of function

Thank you,

Answer:

x = 8
BF = 45

Step-by-step explanation:

Using the given information, we have ...

BH = 2·HF

3x +6 = 2(2x -1)

3x +6 = 4x -2

8 = x

The length of the median is ...

BF = BH + HF

BF = (3x +6) +(2x -1) = 5x +5

BF = 5·8 +5

BF = 45
