<h3>
Answer: (2,0)</h3>
Explanation:
The vector (0,2) points directly north and the length of this vector is 2 units. It's the distance from (0,0) to (0,2).
When rotating 270 degrees counterclockwise, we'll turn to the left or westward direction (90 degrees so far) then at some point aim directly south (180 degrees so far) and finally ultimately end up pointing directly east (after getting to 270). So that's how we go from (0,2) to (2,0).
If you were to go clockwise, then everything flips and you'll ultimately end up pointing directly west. The length of the vector stays the same the whole time.
X= width of the path.
we can suggest this equation:
(20+2x)(28+2x)=1584
we solve this equation:
(20+2x)(28+2x)=1584
560+40x+56x+4x²=1584
4x²+96x-1024=0
4/4x²+96/4x-1024/4=0/4
x²+24x-256=0
We solve this square equation:
x=[-24⁺₋√(576+1024)]/2=(-24⁺₋40)/2
we have two solutions:
x₁=(-24-40)/2=-32 this solution is not valid.
x₂=(-24+40)/2=8
Answer: the width of the path is 8 m.
Answer:
a. (2+3)×4²+1=81
b. (2+3)×(4²+1)=85
c. 2+(3×4²)+1=51
d. 2+3×(4²+1)=53
Step-by-step explanation:
a. Parentheses about the 2 + 3 - then use PEMDAS to give 5 * 16.
b Inserting 2 parentheses makes it 5 * 17 = 85.
c.Inserting the parentheses simplifies it to 2 + 48 + 1 = 51.
d. Inserting the parentheses makes it 2 + 3*17 = 53
A tad more than 29 years, but that depends on the number of times it is being compounded
