The red vector has a magnitude of 22 and makes an angle of 39 degrees with the horizonal x-axis.
Converting to rectangular form: x = 22 cos 39 deg and y = 22 sin 39 deg
Answer:
Area = 324 ft²
Step-by-step explanation:
Given
Length = 15ft
Walkway = 3ft
Required
Determine the area of the pond + the walkway
To calculate the required area, we need to get the total length of a side .
This is calculated by adding the length of a side of the pond and the side of the walkway
Total Length = Pond Length + Walkway
Total Length = 15ft + 3ft
Total Length = 18ft
Now, the required area can be calculated as thus:
Area = Total Length * Total Length
Area = 18ft * 18ft
Area = 324 ft²
Answer: x³+2x²-15x
Step-by-step explanation:
1. Expand
(x²-3x)(x+5)
2. Use the FOIL method: (a+b)(c+d)=ac+ad+bc+bd
x³+5x²−3x²−15x
3. Collect like terms
x³+(5x²−3x²)−15x
4. Simplify
x³+2x²-15x
Hope this helps, have a BLESSED and wonderful day! ;-)
