Answer:
D) h = A/2πr - r
Step-by-step explanation:
A = 2πr(r+h)
A = 2πr² + 2πrh
2πrh = A - 2πr²
h = (A-2πr²)/2πr
=A/2πr - 2πr²/2πr
=A/2πr - r
Answer:
y = x2 - 4x + 2 ; y=x²-4
Step-by-step explanation:
Axis of symmetry = - b /2a
y=x²-2
a = 1 ; b = - 2
x = - (-2) / 2(1)
x = 2/2 = 1
y = x2 - 4x + 2
a = 1 ; b = - 4
x = - (-4) / 2(1)
x = 4/2 = 2
y = x2 + 4x + 2
a = 1 ; b = 4
x = - 4 / 2(1)
x = - 4/2 = - 2
y=x²-4
a = 1 ; b = - 4
x = - (-4) / 2(1)
x = 4/2 = 2
Step-by-step explanation:
set up a proportion for a.
225/30=x/195. x=1462.5 milligrams daily
for b, if he gets 700 mg every 8 hours he only gets it 3 times a day. 700*3 is 2100, which means he is overdosing
Answer:
The stack is inches high.
Step-by-step explanation:
Given date:-
A stack of 7 crates means
1 stack=7 crates
Total number of crate=7
Height of 1 crate =
Height of 1 crate = inches
Height of 1 crate = inches
To find height of stack=?
Now,
Height of a stack = Height of 1 crate Total number of crates
Height of a stack =
Height of a stack =
Height of stack = inches
Therefore the stack is inches high.
Answer:
(a)0.5
(b)0.17
(c)0.625
(b)0.375
Step-by-step explanation:
Pr(E)=0.6
Pr(F)=0.2
(a)Pr (E|F )
(b)Pr (F|E )
(c)Pr (E|F')
Pr(F')=1-P(F)
=1-0.2=0.8
Therefore:
(d)Pr(E'|F')
Therefore:
