The element on the position (1,1) in the product matrix FC is a scalar product of the first row in F and the first column in C.
Therefore the element in the position (1,1) in FC will be a scalar product of (-2,0) and (12,1):
The only matrix that has a value of -24 in the position (1,1) is matrix B.
Therefore, the answer is matrix B.
Answer:
<h2><em><u> 42.8 in</u></em></h2>Step-by-step explanation:
Step one:
given data
we are told that the expression for the depth of a lake after x years is given by
Required
The value of y when x= 4
Step two:
substitute the value of x in the expression to get y
<em><u>After 4 years the depth will increase by 42.8 in</u></em>
It'll be 8 |a^3|.
we don't use modulus on 8 cuz it is obviously positive but we do not know about a^6 when rooted it can be +ve or -ve.
