Answer:
x= -6
Step-by-step explanation:
2(x+5)=x+4 (given)
2x+10=x+4 (distribute)
x+10=4 (simplify)
x= -6 (simplify again)
Answer
Step-by-step explanation:
C
Radius of cone is2.39cmor 2.4cm
volume of cone=45.19cm^3
Pi×r^2×h/3=45.19
22×r^2×7.5/7=45.19×3
r^2=45.19×3×7/22×7.5
r^2=948.99/165
r^2=5.7514545
r=2.39
Or we can say r=2.4cm
Answer:
(f ο g)(-1) = 1
Step-by-step explanation:
Given

f ο g)(-1) = f(g(-1) = f(4(-1)² + 2)
= f(6)
= 
= 
= 1
<u><em>Final answer</em></u>:-
(f ο g)(-1) = 1
