Answer:
-1
Step-by-step explanation:
Rewrite i 14 as ( i 4 ) 3 × i 2 . If i = √ − 1 , then i 2 = − 1 .
From here ( i 2 ) 2 = ( − 1 ) 2 , so i 4 = 1 . If i 4 = 1 ,
then we can say that: i 14 = ( 1 ) 3 × i 2 = i 2 = − 1
C(x)=- 0.3x^2+600x
y=ax^2+bx+c
it shows a upside down parabola equation.
to find maximum value we need to find its vertex(h,k)
as this is a standard quadratic equation we need to see parabolis equation too
y=a(x-h)^2+k
if u see this eq^n K would be the maximum value of Y if x=h.
where h,k are vertex of parabola.
h=-b/2a(derived standard formula)
C(x)=- 0.3x^2+600x
y=ax^2+bx+c
a= -0.3 b=600
h=-600/-0.3
h= 2000
put h in place of x to get K
K= -0.3(2000)^2+600(2000)
K= - 1200000+1200000
K=0
u gets k=0
means C(x)=0
600x= -0.3x^2
600= 0.3x
x=6000/3
x= 2000 units
Answer:
n = 5m + 10 = 5(m + 2), since m + 2 is an integer, then the n is divisible by 5.

Answer:
a=13 b=13
Step-by-step explanation:
Because the triangles are congruent, their corresponding angles will be congruent, too.
So, ∠Y≅∠S and ∠Z≅∠T.
Set the values of these angles equal to each other and solve.
∠Y≅∠S ∠Z≅∠T
4a-4= 48 5b-3= 62
4a=52 5b= 65
a=13 b= 13
