Answer and Step-by-step explanation:
A) False, take (1,-1) and (1,1) both in V, but the sum (2,0) is not
B) True, if A,B are symmetric then A+kB is symmetric as well for k scalar, and zero matrix is symmetric.
C) True. The zero polynom is in V and P+kQ verifies (P+kQ)(0)=P(0)+kQ(0)=0
D) True. zero is solution and f+kg is since all coefficients are linear.
E) True, same than C)
F) False , the zero function doesn't verify that ( and the closure for sum will fail anyway 4+4=8)
G) False, the zero function fail to satisfy this ODE
Answer:
Step-by-step explanation:
For correct scientific notation, we need to have 1 number to the left of the decimal, and everything else to the right. Since our number is already less than 1, the exponent representing the number of places we move the decimal will be negative. We have to move the decimal 5 places to the right to get the 5 to the left of the decimal and everything else to the right, making this:
Answer:
D) 24x + 52
Step-by-step explanation:
The perimeter of the purple rectangle is
P =2(l+w)
=2 (4x+5 + 2x+7)
Combine like terms
=2 (6x+12)
Distribute
= 12x +24
The perimeter of the white rectangle is
P =2(l+w)
P =2(3x+14 +3x)
Combine like terms
=2(6x+14)
Distribute
12x +28
Add the perimeters
12x +24 + 12x +28
24x +52
Answer:
15 muffins are cinnamon.
Step-by-step explanation:
Given that:
Number of muffins baked = 50 muffins
Chocolate chip muffins = 1/5 of 50 =
Chocolate chip muffins = 10 muffins
Blueberry muffins = 1/2 of 50 =
Blueberry muffins = 25
Cinnamon muffins = Muffins baked - chocolate chip muffins - blueberry muffins
Cinnamon muffins = 50 - 10 - 25
Cinnamon muffins = 50 - 35 = 15
Hence,
15 muffins are cinnamon.
