A#b = 2a(7-b)
(2#5)#3
Let us look at the parentheses first.
2#5 = 2*2(7-5)
= 4(2)
= 8
Now the equation becomes 8#3
8#3 = 2*8(7-3)
=16(4)
= 64
The value is 64. Hope this helps!
3/4 is the reduced form, also 12/16 is each doubled
1) 1/5x + 3=0
1/5x=-3
x=(-3)(5)=-15
2)6x-7=0
6x=7
x=7/6=1.17
3) -8/3x+9=0
-8/3x=-9
-8x=-27
x=27/8=3.375
Answer:
Solution given:
y=-1/2 x²
for
f(x)=-1/2 x².
differentiating each term with respect to x
f'(x)=-x
when
x=-4
f'(-4)=4>0 increasing
when
x=-2
f'(-2)=2 >0 increasing
when x=0
f'(0)=0 stationary point.
other points are decreasing
so
largest interval of increasing is
A.X<-2
Answer:
Cosine Ratio
Step-by-step explanation:
Cos = adjacent / hypotenuse
43 is the adjacent and the variable is the hypotenuse.
