X^2 + 5x = -2
x^2 + 5x + 2 = 0
x = -b (+-) sqrt (b^2 - 4ac) / 2a
a = 1, b = 5, and c = 2
x = -5 (+-) sqrt (5^2 - 4(1)(2)) / 2(1)
x = -5 (+-) sqrt (25 - 8) / 2
x = -5 (+-) sqrt (17) / 2
answer is : negative 5 plus or minus the square root of 17 divided by 2
You have to tell them what you think would happen to the earth if the sun disappeared.<span />
Answer:
Lol this is my first time seeing someone saying I bet no one will answer this. Ok coming back to the topic answers are :-
Initial value = -18
Initial value is the output value or the y variable. Looking in the table the y variable is -18 since x is 0.
Rate of change = 0.5
You have to use the formula of rate of change to find the answer. You can choose any pairs from the table and will give you the same answer. I pick the first pair and the last pair to find my rate of change.
(0, -18) and (36, 0)
x1, y1 x2, y2
Rate of change = y2 - y 1 / x2 - x1
Rate of change = 0 - (-18) / 36 - 0
Rate of change = 18 / 36
Rate of change = 0.5
Hope this helps, thank you :) !!
X = 180 - 104 - 22 = 180 - 126 = 54 degrees
y = 180 - 54 = 126 degrees
z = 180 - 126 - 19 = 180 - 145 = 35 degrees
