The answer would be the second one because of the 45-45-90 Right Triangle rule. If the side lengths are the same the the hypotenuse is just the square root of that number.
He had $450 dollars in his savings account. If 1/6 is equal to 75, you will multiply 75 by 6 to get the full amount, which is $450. I hope this helps!
Y=2x and y = x² - 3. To find the intersections of these 2 functions we proceed as follows:
2x= x²-3 → x² - 2x -3 =0
The zeros of this trinomial are x = 3 and x =-1
Now to find y-coordinates replace in any of the initial equation x by both values:
y = 2x . For x = 3 , y = 6
and for a = -1, y = -2
Answer:
x = 4 , y = 2
Step-by-step explanation:
Using the sine / tangent ratios in the right triangle and the exact values
sin60° = and tan60° = , then
sin60° = = = ( cross- multiply )
x = 4 ( divide both sides by )
x = 4
and
tan60° = = = ( multiply both sides by y )
y = 2 ( divide both sides by )
y = 2
C 12.5 hours it would take this long because it adds 3 more people and then you like do something and you subtract that Number by 20 and get 12.5 hours
