Answer:
(a) 9
Step-by-step explanation:

substitute r = 4, t = 2

simplify

cubic of 2 is 8

simplify

Density = Mass/Volume
Density = 6/12 = 0.5 g/mL or 0.5 kg/L
Answer:
0
Step-by-step explanation:
A= (4-1)^3
simplify A to be 3^3
Which gives us 27
B=(2*3)^2-9
simplify B
first multiply the 2 numbers in paranthesis which gives us 6. raise it to the power of 2 which is 39 and then subtract 9. Gives us 27.
C=15^3*4-12
Simplify the exponent first. 3*4 gives us 12 and 12-12 equals 0. Anything raised to the power of 0=1
If A-B^C is the equation we can write 27-27 raised to the power of 1 which is 0
Blinding is part of this, as the participants do not know whether they received the competitor's product.
For this case we have a function of the form
, where
. We must find the values of "and" according to the following function:
So:

Thus, the values are:
24,8, -12
Answer:
24,8, -12
