Answer:
(a) h = A/2πr
(b) 360.375
Step-by-step explanation:
(a) divide both sides by 2πr
h = A/2πr
(b) h= 93 / 2*3.1*2.5
= 360.375
Answers:
1) (s o t)(x)=4x^2-x-4
2) (t o s)(x)=4(x-7)^2-(x-7)+3
Solution:
1) (s o t)(x)=s(t(x))=s(4x^2-x+3)=(4x^2-x+3)-7=4x^2-x+3-7
(s o t)(x)=4x^2-x-4
2) (t o s)(x)=t(s(x))=t(x-7)=4(x-7)^2-(x-7)+3
(t o s)(x)=4(x-7)^2-(x-7)+3

Answer:
Step-by-step explanation:
The formula for simple interest is expressed as
I = PRT/100
Where
I represent the interest
P represents the principal or amount invested
R represents interest rate on the principal.
T represents time in years.
From the information provided,
P = $250
R = 16%
T = 18 years
Therefore
I = (250 × 16 × 18)/100 = $720
Total amount after 18 years would be 250 + 720 = $970
