True or false: (a) If A2 is defined then A is necessarily square. (b) If AB and BA are defined then A and Bare square. (c) If AB and BA are defined then AB and BA are square. (d) If AB
Answers
(a) True. Suppose A is a not a square matrix, with m rows and n columns. Then A² is not defined, because you can't multiply an m×n matrix by another m×n matrix.
(b) False. As an example, consider the matrices
[tex]A_{3\times2} = \begin{bmatrix}1&0\\0&1\\0&0\end{bmatrix}[/tex]
[tex]B_{2\times3} = \begin{bmatrix}-1&0&1\\0&0&1\end{bmatrix}[/tex]
Then both AB and BA are defined, with
[tex]AB_{3\times3} = \begin{bmatrix}-1&0&1\\0&0&1\\0&0&0\end{bmatrix}[/tex]
[tex]BA_{2\times2} = \begin{bmatrix}-1&0\\0&0\end{bmatrix}[/tex]
In general, you can multiply any m×n by any n×m matrix.
(c) True. Multiplying a m×n matrix by a n×m matrix always yields a m×m matrix, and multiplying a n×m matrix by a m×n matrix always yields a n×n matrix.
jenny is a 60 percent free-throw shooter She gets to shoot a second free throw if and only if she makes her first shot. She can score 0 points( if she misses her first shot), 1 point (she makes her first but misses her second), or 2 points ( she makes both shots.)
Assuming that the probability for each shot is independent, what number of points is Jenny most likely to make?
Assuming that the probability for each shot is independent,how many points on average, can jenny expect to make when she shoots a one-and-one (when she only gets a second shot if she makes the first)?
suppose jenny gains confidence after making her first free throw and the probability of her making the second free throw goes up to 70%. now, what number of points is jenny most likely to make when she shoots a one-and-one?

Answer:
[tex]x=\sqrt{40}, y=\sqrt{104}[/tex]
Step-by-step explanation:
Note the triangle formed by x, y, and 8 is similar to the largest triangle
so x : c = 8 : y = y : 13, where c is the rightmost vertical length, c² = x² + 5²
From 8 : y = y : 13, we get
y² = 13*8 = 104, so
[tex]y=\sqrt{104}[/tex]
From x : c = 8 : y, we have xy = 8c
x²y² = 64c²
104x² = 64(25 + x²)
104x² = 1600 + 64x²
40x² = 1600
x² = 40
[tex]x=\sqrt{40}[/tex]
A cylinder has a cross-section circumference of 56cm. The height of the cylinder is 3.2cm. Calculate the volume and surface area of the cylinder.
Answers
Answer:
volume = 798.58 cm³ (nearest hundredth)
surface area = 678.31 cm³ (nearest hundredth)
Step-by-step explanation:
Volume of a cylinder: [tex]V=\pi r^2h[/tex]
Surface area of a cylinder: [tex]SA=2\pi r^2+2\pi rh[/tex]
Circumference: [tex]C=2\pi r[/tex]
(where r is the radius and h is the height)
Given circumference = 56
⇒ [tex]56 = 2\pi r[/tex]
⇒ [tex]r=\dfrac{56}{2\pi }=\dfrac{28}{\pi }[/tex]
[tex]V=\pi \left(\dfrac{28}{\pi}\right)^2 \times3.2=\dfrac{2508.8}{\pi}=798.58 \textsf{ cm}^3 \textsf{ (nearest hundredth)}[/tex]
[tex]SA=2\pi \left(\dfrac{28}{\pi}\right)^2+56 \times3.2=\dfrac{1568}{\pi}+179.2=678.31 \textsf{ cm}^3 \textsf{ (nearest hundredth)}[/tex]

A shipping container will be used to transport several 60-kilogram crates across the country by rail. The greatest weight that can be loaded into the container is 24000 kilograms. Other shipments weighing 3300 kilograms have already been loaded into the container. Write and solve an inequality which can be used to determine xx, the number of 60-kilogram crates that can be loaded into the shipping container.
Answers
Step-by-step explanation:
60x + 3300 = 24000
60x = 24000 - 3300
60x = 20700
x = 20700 ÷ 60
x = 345
x ≤345

A cell phone company charges $50 plus $40 per line each month. Luke must spend under $170 on his family's cell phone bill each month. How many cell phones can his family have?
Answers
The equation that's been computed shows that the number of cell phones that his family can have will be 2.
How to solve the equationFrom the question, it was stated that the cell phone company charges $50 plus $40 per line each month and that Luke must spend under $170 on his family's cell phone bill each month.
Let the number of cell phones that can be bought be represented by x.
The equation to solve the question will be:
50 + 40(x) < 170
50 + 40x < 170
Collect like terms
40x < 170 - 50
40x < 120
x < 120/40
x < 3
Therefore, the number of cell phones has to be less than 3. Hence, this will be 2.
