Part 1) 
Part 2) 
Part 3) 
Step-by-step explanation:
<u><em>The question in English is</em></u>
Expressed in algebraic language.
Symbolically write the following expressions:
Three times a number:
Four times a number:
Two-thirds of a number
Let
n ----> the number
Part 1) we have
Three times a number:
we know that
The algebraic expression is equal to multiply 3 by the number n
so

Part 2) we have
Four times a number:
we know that
The algebraic expression is equal to multiply 4 by the number n
so

Part 3) we have
Two-thirds of a number
we know that
The algebraic expression is equal to multiply the fraction 2/3 by the number n
so

Answer:
The length of the waterline when hull speed is 4 knots per hour in feet is 2.985 feet.
Step-by-step explanation:
Let the function
, where
is the length of the waterline, measured in feet and
is the hull speed of the boat, measured in knots per hour. If we know that
, then the length of the waterline is:



The length of the waterline when hull speed is 4 knots per hour in feet is 2.985 feet.
Prime numbers are 2,3,5,7,11,13,17,19,23 that's 9 of them the other 16 are not prime (1,4,6,8,9,10,12,14,15,16,18,20,21,22,24,25)
so 16/25 or 64% is the probability of not getting a prime number
set x=0 to get insights.
at x=0 to the functions are
-2(0-2)²+3 = -5
-2(0+2)²-3 = -11
-2(0-2)²+3 = -5
-2(0-2)²-3 = -11
weird, for some reason option 1 and 3 seem to be the same, maybe that's an accident by the author.
maybe a + was intended inside the parentheses, dunno.
option 1 and 3 seem fine, although I think there is an error in the options. they shouldn't be exactly the same
