Answer:
First Option 
Step-by-step explanation:
To graphically add two vectors a and b using the -tail and tip-method, you must draw the tail of b at the tip of the vector a. Then you must draw a line that goes from the tail of a to the tip of b. This line represents the sum of
.
In this problem, notice that the tail of the vector w is on the tip of the vector v. The line that joins the tail of v with the tip of w is u.
Therefore we can say that
.
The answer is the first option
Answer:
In Euclidean geometry, a regular polygon is a polygon that is equiangular (all angles are equal in measure) and equilateral (all sides have the same length).
Dual polygon: Self-dual
Step-by-step explanation:
Answer:
let length be l
breadth=l-10m
area of rectangular park=236m²
Step-by-step explanation:
area of rectangular park=236m²
l×(l-10)=236
l²-10l-236=0
l²-2.l.5+5²-236-5²=0
(l-5)²-236-25=0
(l-5)²=261
(l-5)=√261
(l-5)=16.15
l=16.15+5=21.15
b=l-10=21.15-10=11.15
Answer:
9.48
Step-by-step explanation:
The perimeter of a rectangle is the distance around the the shape. It can be found by adding each side of the shape to find a total. In contrast, the area of a shape is the amount inside a shape. It is found using multiplication or A = l*w. Since the width is w and the length is twice its width or 2w, use these expressions in the area formula to find their amount. Then add them together to find the perimeter.

The width of the rectangle is w = 1.58. The length is 2w = 2 (1.58) = 3.16.
Add these amounts by P = l + l + w + w to find the perimeter.
P = 3.16 + 3.16 + 1.58 + 1.58 = 9.48
Answer:
a¹⁰
Step-by-step explanation:
So here we have (a⁵)², meaning we need to multiply the exponents to get a¹⁰
