Answer:
surface area= 36
Step-by-step explanation:
Step-by-step explanation:
let the amount that Krutika gets be x, therefore, gets him the amount that jim get will be x +40
therefore 3/1=x+40/x
hence 3x=x+40
therefore x=40/2
x=20
I believe the answer is D
Answer:
f(-6)= -4
Step-by-step explanation:
f(x)=8+2x for f(-6)
-----
x= -6
substitute: 8+2(-6)
simplify using PEMDAS: 8+ (-12)
simplify using PEMDAS: -4
Since the vertex form of a parabola is y=a(x-h)^2+k with h and k being the vertex (the x and y values, respectively), we get a(x-0)^2+20=ax^2+20. Plugging (10, 8) in to find a, we get 8=a(10)^2+20=a*100+20. Subtracting 20 from both sides, we get -12=100*a. Next, we divide 100 from both sides to get a=-12/100. Since h=0 and k=20, we have your answer!
