Answer:
about 2.9° north of east
Step-by-step explanation:
If we orient the directions so north is in the +y direction and east is in the +x direction, the car is traveling 13 km at an angle of -45°, then 16 km at an angle of +40°. We can add these vectors by adding their components in the x- and y-directions.
13(cos(-45°), sin(-45°)) ≈ (9.19239, -9.19239)
16(cos(40°), sin(40°)) ≈ (12.25671, 10.28460)
The sum of these vectors is then ...
= (21.44910, 1.09221)
and the resultant angle is ...
arctan(1.09221/21.44910) ≈ 2.915° . . . . measured north of east
The resultant direction is about 2.9° north of east.
You add 1/4 each year:
800 to 1000 in one year
1000 to 1250 in 2
1250 to around 1812.5
Answer:
The unknown number is -3
Step-by-step explanation:
Represent unknown as x
Write as an equation
12 + (x * 5) = -3
Multiply
12 + 5x = -3
Subtract -5x from both sides of the equation
12 = -3 - 5x
Add 3 to both sides of the equation
15 = -5x
Divide both sides by -5
x = -3
The unknown number is -3
Hope this helps :)
Answer:
52
Step-by-step explanation:
First find out how many beads cover 1 inch of the string which is 4 beads then multiply that number, 4, by the length of the string, 13. You should get 52.
