Answer:
y(x) = -2x -8
Step-by-step explanation:
using the hint, insert the points (x,y) in the equation:
-2 = -3m + b eq1
2 = -5m + b eq2
eq2 - eq1 :
4 = -2m ==> m = -2
insert m in eq1:
-2 = -3*(-2) +b ==> b = -8
Answer:
C. 48
Step-by-step explanation:
336/7 is 48
Cos x = 1/√10
sin x = √( 1 - 1 /10 ) = √9/10 = - 3/√10 ( because x is in Q IV )
cot 2 x = cos 2 x/sin 2x = ( cos²x - sin²x)/ (2 sinx cosx ) =
= ( 1/10 - 3/10 )/(2 * (-3/√10)*1/√10)= (- 8/10 ) / (-6/10 ) = 8/6 = 4/3
Answer:
I'm pretty sure the Volume of pyramid is

Step-by-step explanation:
Answer:
i believe the answer is C
Step-by-step explanation:
3.78 meters = 378 cm
5.25 meters = 525 cm
378 x 525 = 198,450
198,450 / 42 = 4725
4725 which is a whole number
