Answer:
Step-by-step explanation:
V, r, h are the volume, radius, and height, respectively.
V = πr²h = 9πr²
The only error in your previous answers was that you forgot the π.
if r = 1, V = 9π1² = 9π ≅ 28 in³
if r = 2, V = 9π2² = 36π ≅ 113 in³
if r = 3, V = 9π3² = 81π ≅ 254 in³
Answer:
Step-by-step explanation:
f(h(-2) =
h(-2)= 5(-2)= -10
f(-10)= -10 - 2 = -12
A variety of genes are involved in the control of cell growth and division. ... Tight regulation of this process ensures that a dividing cell's DNA is copied properly, any errors in the DNA are repaired, and each daughter cell receives a full set of chromosomes.
Step-by-step explanation:
I am not fully sure what your teacher is aiming for. it friends very much on what you were just discussing in class (which I don't know).
but the first thing coming to mind is a minus sign ("-"). squaring a negative number removed the minus and makes the result equal to squaring the same positive number.
just for the undoing the 1/2 :
that is, because a fraction as exponent specifies in its denominator the root to be calculated for the basic value or expression.
so, 1/2 means square root. and yes, square is the inverse function of a square root, and it "undoes" the square root.
in exponent calculation it just means that for exponent 1 to the power of exponent 2 we simply multiply both exponents. and so, 1/2 × 2 = 1
FYI - the numerator still represents an original "to the power of" operation.
so, e.g. 3/2 would mean put the basis to the power of 3 and then do the square root of that result. or the other way around. these operations are commutative (the sequence does not matter).
