Answer:
x = -pi/2
Step-by-step explanation:
hello :
f(x)=sin x x⋲(-2pi,0)
the derivate for f is : f'(x) = cosx
f(x) achieve a minimum when : f'(x) =0
cosx = 0 genral solution is :
x = pi/2 +kpi .. k in Z
but : x⋲(-2pi,0) so : x = -pi/2.....(k = -1)
Answer:
Please see below :)
Step-by-step explanation:
The slope is just what's in front of the x!
So:
1.) slope = -1/4
2.) slope = undefined
3.) slope = -9
4.) slope = 9/2
Hope this helps!
Answer:
☑ The area of the circle depends on the square of the radius.
☑ The area of circle D is 324π cm²
Step-by-step explanation:
The area of a trapezium is the product of height and average base length. The average base length is
(126 cm^2)/(9 cm) = 14 cm
One base is half the difference longer than this, 16.5 cm; the other is half the difference shorter, 11.5 cm.
You answer should be 7/12, or aprox. 0.58 (I could be wrong)
You need to divid the number of outcomes that will satisfy your probability (anything that’s not 4,10,2,3, or 11, so there are 7 numbers left) by the total number of outcomes, (12), and that’s your answer
