x
Step-by-step explanation:
I AM WRONG I THINK....... THANKS FOR DEM POINTS BRODA OR SISTA
The answer is 65° because 115° and another number has to add up to 180°
I see your last line is : c(x) = 0.9(x^2-10)^2 + 101.1
Let y = x^2, then c(y) = 0.9(y-10)^2 + 101.1
Apparently, c(y) is a parabola, min is 101.1 when y = 10, max is infinity
So let x^2 = 10 -> x = sqrt(10) or -sqrt(10), min is 101.1, max is infinity
Answer:
840
Step-by-step explanation:
(−30)(−7) − (210)(−3)
=210 − (210)(−3)
=210 − (−630)
=840
Hope this helps!
brainliest?

Answer:
Step-by-step explanation:
The graph is done using Desmos. Just by substitution x = 1 will force the graph to go to y = 0, but graphs are not always that good. This one gets 1.111
to get y = 0. I'd use 1 if you had to answer it and a computer will mark it.
