Select all the sums that are positive.
A. –5 + (–2)
B. 5 + (–2)
C. –3 + 4
D. 0 + (–3)
E. –2 + 4
Answers
Answer:
The positive sums are:
B. 5 + (–2)
C. –3 + 4
E. –2 + 4
Step-by-step explanation:
We can simply observe the sums to conclude that the sum will be positive or negative.
A. –5 + (–2)
We can see that both numbers are negative, the sum of two nu=egative numbers is also negative.
-5+(-2) = -5-2 = -7
B. 5 + (–2)
The number with greater magnitude is positive so the sum will also be positive.
5 + (–2) = 5-2 = 3
C. –3 + 4
The number with greater magnitude is positive so the sum will also be positive.
-3+4 = 1
D. 0 + (–3)
The number with greater magnitude is negative so the sum will also be negative.
= 0-3 = -3
E. –2 + 4
The number with greater magnitude is positive so the sum will also be positive.
-2+4 = 2
Hence,
The positive sums are:
B. 5 + (–2)
C. –3 + 4
E. –2 + 4

A broker charges customers a fixed fee of £150 plus 5.50% of the amount of all investments made. If a customer invests £40 000 through the broker, what is the total brokerage payable?
(10 Marks)
Answers
Answer:
Total payable brokerage = £2350
Step-by-step explanation:
Given that:
Fixed fee charged by broker = £150
Percent of fee charged = 5.50%
Amount invested by customer = £40,000
Fee charged = [tex]\frac{5.50}{100}*40000[/tex]
Fee charged = 5.50 * 400 = £2200
Total brokerage payable = £150 + £2200 = £2350
Hence,
Total payable brokerage = £2350

Example 24 In a school there are 20 teachers who teach mathematics or physil
these, 12 teach mathematics and 4 teach both physics and mathematics. How Ex
teach physics ?
Answers
Answer:
The number of teachers who teach physics n(P) = 12
Step-by-step explanation:
Step(i):-
Given that the number of teachers who teach mathematics or physics
n(MUP) = 20
Given that the number of teachers who teach mathematics
n(M) = 12
Given that the number of teachers who teach both mathematics and physics
n(M∩P) = 4
Step(ii):-
By using n(A∪B) = n(A) + n(B) - n(A∩B)
n(M∪P) = n(M) +n(P) - n(M∩P)
20 = 12 + n(P) - 4
20 -12 +4 = n(P)
n(P) = 12
Final answer:-
The number of teachers who teach physics n(P) = 12

Step-by-step explanation:

This is arithmetic sequence
first term = 10
Common difference = 2nd term - first term
d = 4 - 10
d = -6
nth term = a₁ + (n -1)d
= 10 + (n - 1)*(-6)
= 10 + n*(-6) - 1*(-6)
= 10 - 6n + 6
= 10 + 6 - 6n
= 16 - 6n

skew-symmetric 3 x 3 matrices form as subspace of all 3 x 3 matrices and find a basis for this subspace.
Answers
Answer:
a) ∝A ∈ W
so by subspace, W is subspace of 3 × 3 matrix
b) therefore Basis of W is
={ [tex]{\left[\begin{array}{ccc}0&1&0\\-1&0&0\\0&0&0\end{array}\right][/tex] [tex],\left[\begin{array}{ccc}0&0&1\\0&0&0\\-1&0&0\end{array}\right][/tex] [tex],\left[\begin{array}{ccc}0&0&0\\0&0&1\\0&-1&0\end{array}\right][/tex]}
Step-by-step explanation:
Given the data in the question;
W = { A| Air Skew symmetric matrix}
= {A | A = -A^T }
A ; O⁻ = -O⁻^T O⁻ : Zero mstrix
O⁻ ∈ W
now let A, B ∈ W
A = -A^T B = -B^T
(A+B)^T = A^T + B^T
= -A - B
- ( A + B )
⇒ A + B = -( A + B)^T
∴ A + B ∈ W.
∝ ∈ | R
(∝.A)^T = ∝A^T
= ∝( -A)
= -( ∝A)
(∝A) = -( ∝A)^T
∴ ∝A ∈ W
so by subspace, W is subspace of 3 × 3 matrix
A ∈ W
A = -AT
A = [tex]\left[\begin{array}{ccc}o&a&b\\-a&o&c\\-b&-c&0\end{array}\right][/tex]
= [tex]a\left[\begin{array}{ccc}0&1&0\\-1&0&0\\0&0&0\end{array}\right][/tex] [tex]+b\left[\begin{array}{ccc}0&0&1\\0&0&0\\-1&0&0\end{array}\right][/tex] [tex]+c\left[\begin{array}{ccc}0&0&0\\0&0&1\\0&-1&0\end{array}\right][/tex]
therefore Basis of W is
={ [tex]{\left[\begin{array}{ccc}0&1&0\\-1&0&0\\0&0&0\end{array}\right][/tex] [tex],\left[\begin{array}{ccc}0&0&1\\0&0&0\\-1&0&0\end{array}\right][/tex] [tex],\left[\begin{array}{ccc}0&0&0\\0&0&1\\0&-1&0\end{array}\right][/tex]}
