Hello!
You put -1 in for x
F(-1) = (-1)^5 + (-1 + 3)^2
F(-1) = -1 + (2)^2
F(-1) = -1 + 4
F(-1) = 3
The answer is 3
Hope this helps!

Answer:
68
Step-by-step explanation:
Find the vanilla first by dividing 420 by 7 and multiplying the quotient by 2 to get 120.
Then find the banana using the equation 35/100 = x/420, cross multiply to get 147.
Add 120 and 147 to get 267.
Subtract 267 from 420 to get 153.
Divide 153 by 9 to get 17.
Get the number of lemon cakes by multiplying 17 by 4. 
The number of lemon cakes is 68!
(and chocolate cakes is 85)
 
        
             
        
        
        
A. False. Consider the identity matrix, which is diagonalizable (it's already diagonal) but all its eigenvalues are the same (1).
b. True. Suppose 

 is the matrix of the eigenvectors of 

, and 

 is the diagonal matrix of the eigenvalues of 

:


Then

In other words, the columns of 

 are 

, which are identically 

, and these are the columns of 

.
c. False. A counterexample is the matrix

which is nonsingular, but it has only one eigenvalue.
d. False. Consider the matrix

with eigenvalue 

 and eigenvector 

, where 

. But the matrix can't be diagonalized.
