Cho ánh xạ tuyến tính f: R³⇒R³ và hai cơ sở của R³ B={b1=(1;3;3),b2=(-3;6;5),b3=(1;2;2 )}
C={c1=(2;0;3),c2=(-5;-1;-5).c3=(1;0 ;1)}
Biết f(b1)=(-5;6;4), f(b2)=(-8;5;2). f(b3)=(=9;-2;-5)
a) tìm ma trận A=[f]E3 từ đó suy ra biểu thức của f(x1;x2;x3)
b tìm ma trận [f]B
c từ [f]B tính ma trận[f]CB

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5

answer: none of these answers are correct only the second half is
