Answer:
The value of m is 
.
Step-by-step explanation:
If two vectors 
and 
are perpendicular to each other then their dot product will be zero i.e 
If two vectors and are parallel to each other then their cross product will be zero i.e 
Given vectors are a= (3,4) and b=(m,2)
The position vector of 
is =
The position vector of 
is =
Since and are perpendicular.
Then,
⇒3.m +4.2=0
⇒3m+8=0
⇒3m= -8
The value of m is .
Edit: I have poor vision! My anwser was incorrect
Answer: m= -3/4
Step-by-step explanation:
can start by looking at the squares of the graph and do the rise over run
. Since it goes down it’s fall over crawl. -3/4
The area of the composite figure = 10,874.1 sq. m.
The perimeter of the composite figure = 406.9 m
<h3>What is the Area and Perimeter of a Rectangle and Circle?</h3>
Perimeter of a rectangle = 2(length + width)
Area of a rectangle = length × width
Perimeter of a circle = 2πr
Area of a circle = πr²
<h3>
What is Area of the
composite figure?</h3>
The figure is made up of two semicircles (1 full circle) and a rectangle.
Area of the composite figure = area of circle + area of rectangle
= πr² + length × width
r = 36.5 + 1.2 = 37.7 m
length = 85.0 m
width = 2(36.5) + 2(1.2) = 75.4 m
Substitute
Area of the composite figure = π(37.7)² + 85.0 × 75.4 = 10,874.1 sq. m.
<h3>
What is Perimeter of the
Composite Figure?</h3>
Perimeter of the composite figure = perimeter of circle + 2(length of the rectangle)
= 2πr + 2(L)
Plug in the values
= 2π(37.7) + 2(85.0)
Perimeter of the composite figure = 406.9 m
