Suppose you have two 3 by 3 matrices ,say A and B How can the square of the A and B be mathematically expressed a).AB² b).[AB]² Which one the two is correct?
Answer:
[tex][AB]^2[/tex]
Step-by-step explanation:
Given
Matrices A and B
Required
Represents the square of A and B
The interpretation of the question is that:
The square of the product of A and B
This can be represented as:
The square(product of A and B)
Product means *
So, we have:
The square(A * B)
The square means ^2
So, we have:
[tex][A * B]^2[/tex]
This gives:
[tex][AB]^2[/tex]
Hence, the second option is correct

3. Sue's average for 9 games of bowling is 108. What is the lowest score she can receive for the
tenth game to have an average of 110?
Answer: 128
Step-by-step explanation:
Sue's average for 9 games of bowling is 108. Therefore, the total scores for the 9 games is:
= 108 × 9
= 972
To have an average of 110 in 10 games, her total score will be:
= 110 × 10
= 1100
Therefore, the lowest score that she can get will be the difference between the values calculated above and this will be:
= 1100 - 972
= 128
please help !! thank you so much!!
Step-by-step explanation:
we know that:
[tex]tan(x - y) = \frac{tanx - tany}{1 + tanx \times tany} [/tex]
using this, we can see that x = 73 and y = 13
using this, tan(x-y) = tan(73-13) = tan(60)
therefore, A = 60
we know that tan(60) = √3
therefore, B = 3

Answer:
[tex] - 12288 \div {2}^{11} = - 6 \\ forth \: answer \: is \: correct[/tex]
Answer:
4th option
Step-by-step explanation:
The nth term of a geometric sequence is
[tex]a_{n}[/tex] = a₁ [tex](r)^{n-1}[/tex]
where a₁ is the first term and r the common ratio
To find a₁ use a₁₂ = - 12288 , then
a₁ [tex](2)^{11}[/tex] = - 12288 , that is
a₁ × 2048 = - 12288 ( divide both sides by 2048 )
a₁ = - 6
Then the explicit formula is
[tex]a_{n}[/tex] = - 6 . [tex]2^{n-1}[/tex]

A magazine contains fourteen pages. You open to a random page.
Find the probability that the page number is 3 or 7.
“Or” meaning they want both. Since they each represent 1/14 add them together. 1/14+1/14=2/14. Then simplify 2/14 to get 1/7
So, the answer the 1/7

Scarlett needs to order 6,318 binder clips for an upcoming conference. If the binder clips come in
boxes of 39, how many boxes should Scarlett order?
boxes

Step-by-step explanation:
Divide 6,318 divided by 39 and you get 162.
Plus why defuk she need that manny binder clip. Does she eat them
Answer:
6318 / 39 = 162 boxes.
This question does not really make sense because you ask how many boxes are needed, then say that the clips are coming in 39 boxes.

Aisha collects 1p coins and 2p coins. 24 of these are 1p coins. The probability of choosing a 2p coin at random is 1/2 How much money does she have in total?
Answer:
Aisha has 24 2p coins and 24 1p coins, then she has in total:
2p*(24) + 1*p*(24) = 48p + 24p = 72p
Step-by-step explanation:
Suppose that we have a set of N elements in a bag (if the bag is closed and we put our hand inside to grab one element, we could not distinguish them apart), and K of these elements have a given property (for example, these are red).
The probability of selecting at random one of these red elements is equal to the quotient between the number of elements with that property (K) and the total number of elements in the bag (N)
P = K/N
Now let's go to our problem.
We have 24 1p coins.
We have X 2p coins.
Then the total number of coins is: (24 + X)
We know that the probability of choosing at random a 2p coin is then:
P = X/(24 + X)
And we know that this is equal to 1/2
Then:
X/(24 + X) = 1/2
X = (1/2)*(24 + X) = 24/2 + X/2
X = 12 + X/2
X - X/2 = 12
X/2 = 12
X = 2*12 = 24
Then Aisha has 24 2p coins.
Aisha has 24 2p coins and 24 1p coins, then she has in total:
2p*(24) + 1*p*(24) = 48p + 24p = 72p
The surface of a pedestrian bridge forms a parabola. Let the surface at one side of the bridge be represented by (4,0) and the surface at the other side be represented by (8,0). The center of the bridge is 3 feet higher than each side and can be represented by a vertex of (6,3). Write a function in vertex form that models the surface of the bridge.
Answer:
y = -3/4(x - 6)^2 + 3
Step-by-step explanation:
y = ax^2 + bx + c
(4, 0)
16a + 4b + c = 0 Eq. 1
(8, 0)
64a + 8b + c = 0 Eq. 2
(6, 3)
36a + 6b + c = 3 Eq. 3
We have a system of three equations in three variables.
Eq. 2 - Eq. 1
48a + 4b = 0 Eq. 4
Eq. 2 - Eq. 3
28a + 2b = -3 Eq. 5
Eq. 4 - 2 * Eq. 5
-8a = 6
a = -6/8
a = -3/4
48a + 4b = 0
48(-3/4) + 4b = 0
4b = 36
b = 9
16a + 4b + c = 0
16(-3/4) + 4(9) + c = 0
-12 + 36 + c = 0
c = -24
The equation of the parabola is
y = -3/4 x^2 + 9x - 24
y = -3/4(x^2 - 12x + 32)
y = -3/4(x^2 - 12x + 36) + (-3/4)32 - (-3/4)(36)
y = -3/4(x^2 - 12x + 36) -24 + 27
y = -3/4(x - 6)^2 + 3

What are the coordinates of Rx=3(G)?
Answer:
When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places. If you reflect over the line y = -x, the x-coordinate and y-coordinate change places and are negated (the signs are changed). the line y = x is the point (y, x). the line y = -x is the point (-y, -x).

Step-by-step explanation:
We can graph this line using the equation given to us. The equation is in slope-intercept form, [tex]y=mx+b[/tex]. In this form, [tex]m[/tex] = slope and [tex]b[/tex] = the y-intercept.
So, we can tell that the slope is -[tex]\frac{1}{5}[/tex] and the y-intercept is (2,0).
We begin by plotting on the graph the y-intercept, (2,0).
The slope also equals the [tex]\frac{rise}{run}[/tex]. The slope is negative, so the line will slope down. From the point we have plotted, we will rise negative 1 unit. This means to move down 1 unit. From this point, we will run 5 units. Because the line is negative, we will move 5 units to the left, not the right. We land on point (5,1).
Now, we will draw a line from these two points. This is the line shown in the equation.
Good luck ^^

Los ingresos de Mary en 2019 fueron un 20 por ciento mayores que sus ingresos en 2018. ¿Cuál es la relación entre los ingresos de Mary en 2019 con respecto a sus ingresos en 2018?
a) 1 a 5
b) 5 a 6
c) 6 a 5
d) 5 a 1
e) 20 a 1
Answer:
La respuesta correcta es la opción d) 5 a 1.
Step-by-step explanation:
Para calcular la relación entre los ingresos de Mary en 2019 ([tex]I_{2019}[/tex]) con respecto a sus ingresos en 2018 ([tex]I_{2018}[/tex]), partimos de que los ingresos de Mary en 2019 fueron un 20% mayores que sus ingresos en 2018:
[tex]I_{2019} = 20\% \: I_{2018}[/tex]
[tex] I_{2019} = \frac{20}{100}I_{2018} [/tex]
[tex] \frac{100}{20}I_{2019} = I_{2018} [/tex]
[tex] 5I_{2019} = I_{2018} [/tex]
Entonces, la relación entre los ingresos de Mary en 2019 es 5 veces los ingresos de Mary en 2018. Por lo tanto, la respuesta correcta es la opción d) 5 a 1.
