Answer:
A) False - not a right angle
B) True - it is a right angle
C) True - it is a right angle
D) False-not a right angle
Step-by-step explanation:
A) a*a+b*b=c*c (Asquared+Bsquared=C squared)
2*2+ 3*3 = 4*4
4+9=16
13 does not equal 16
B) 5*5+12*12=13+13
25+144=169
169=169 - True
C) 3*3+4*4=5*5
9+16=25
25=25 (True)
D) 4+ Root of 3 = Root of 19
False - square root of a prime number is irrational
Answer:
C

I did this question today, pls lmk if u get it right
Depends on what kind of a triangle
Answer:
x= -11/4 is a maximum.
Step-by-step explanation:
Remember that a function has its critical points where the derivative equal zero. Therefore we need to compute the derivative of this function and find the points where the derivative is zero. Using the chain rule and the product rule we get that

And then we get that if
then
. So it has a critical point at
.
Now, if the second derivative evaluated at that point is less than 0 then the point is a maximum and if is greater than zero the point is a minimum.
Since
x= -11/4 is a maximum.
