Answer:
A
Step-by-step explanation:
P^T is transpote matrix. So the rows of matrix P you write like columns in P^T.
So we have first row: 2, 5, it will be firsl column
2nd row: 8,1 will be 2nd column.
It is matrix:
2 8
5 1
This is matrix a)
Answer:
A
Step-by-step explanation:
Answer:
1. B) Figure B.
2. C) Figure C.
3. D) Figure D.
4. C) Figure C.
Step-by-step explanation:
Given: Radius of Circle A= 4
Radius of Circle B= 5
Radius of circle C= 6
Radius of circle D= 7
Now, finding circumference and area of all the circle.
We know, circumference of circle=
Area of circle=
Where, r= radius of circle and π = 3.14
First, solving for figure A
Circumference=
Area=
Solving for Figure B
Circumference=
Area=
Solving for Figure C
Circumference=
Area=
Solving for Figure D
Circumference=
Area=
∴ 1. Answer is Figure B.
2. Answer is figure C.
3. Answer is Figure D
4. Answer is Figure C.
Answer:
x=2
Step-by-step explanation:
5x +(3-1) =12
5x +2 =12
5x =12-2
5x =10
x =10÷5
x =2
Answer:
11 cm
Step-by-step explanation:
As Y is midpoint if XZ
XY=YZ=2a+1
WZ=WX+XY+YZ=28
a+1+2a+1+2a+1=28
5a+3= 28
5a=25
a=5
XY=2a+1
=2(5)+1
=10+1
=11 cm
