Step-by-step explanation:
obtuse angle is an angle whose measure is more than 90 degree but less than 180 degree..
So,
170°
Check the picture below.
the piecewise function, has two subfunctions or behaviours, one if x < 1, meaning less, not equals, but less than 1, so it doesn't include one, so it has a "hole" on that endpoint.
and the second behaviour of the piecewise is if x ⩾ 1, larger or equals than 1, so it includes 1, so it has a solid ball on that endpoint.
Answer:
a. shown below
b. 9x+14
Step-by-step explanation:
a. (on the bottom)
b. (3x+7)(3x+2)
multiply the terms:
9x+14
thats the area
