Answer:
D sqrt( A ) sqrt(pi) / pi = r
Step-by-step explanation:
The area of a circle is given by
A = pi r^2
To find r
Divide each side of the equation by pi
A / pi = pi r^2 /pi
A / pi = r^2
Take the square root of each side
sqrt(A / pi )= sqrt( r^2)
sqrt(A / pi )= r
We do not like leaving square roots in the denominator, so multiply by sqrt(pi)/sqrt(pi))
sqrt(A / pi ) *sqrt(pi)/sqrt(pi))
sqrt( A ) sqrt(pi) / pi = r
Answer: it is an exponential decay function
Step-by-step explanation:
Since 0.3 is less than 1 then increasing the value of the x will lead to the decrease of the value function y
Answer:
independent, 1/4
Step-by-step explanation:
The events are independent because what occurs on the first flip does not affect the second flip
P(heads) = 1/2
P(heads, heads) = 1/2*1/2 = 1/4
Answer:
50
Step-by-step explanation:
<em>Substitute</em> 7 as x in the original equation, (9x-13)
<u>9(7)-13</u>
1) Multiply 9 and 7:
63-13
2) Subtract:
50
Answer:
Hey you were the one I helped before right?
