Answer:
(-pi, 0)
Step-by-step explanation:
From the graph, we have 3 stationary point; the first one at x = 0, the second one at x = 1 and the last one at x = 2.
The function is increasing at two intervals.
The first increase is between x = -1 and x = 0.
The second increase is between x = 1 and x = 2.
From the choices give the interval that represent increase is (-pi, 0)
Answer:
x = 20
Step-by-step explanation:
In similar polygons, all corresponding sides are proportional. The scale factor between AB and DE is the same as between AC and DF.
You can confirm that by plugging it back into the original equation:
1/2x+9=2x/2-1. I hope this meets ur criteria. It works and equals 20.
Answer:
-108
Literally just put what you wrote in the calculator
Step-by-step explanation:
4 • (-9) • (-3) • (-1)
In a right triangle the biggest angle is 90°.
Then the two smaller angles sum up 180° - 90° = 90 °.
Now you can use this equation: 3x + 6 + 2x - 1 = 90 and solve for x:
5 x + 5 = 90
5x = 85
x = 85/5
x = 17
Then, the smallest angle is 2(17) - 1 = 33°
