Answer:
Option 3 -
Step-by-step explanation:
Given : Options in the figure.
To find : Which of the following is a complex number?
Solution :
Complex number is defined as the number which contains real number along with imaginary number.
The complex number is in the form of a+ib.
Now, we determine one by one.
Option 1 - -7
-7 is the real number not complex.
Option 2 -
is the real number not complex.
Option 3 -
is in the form a+ib so it is a complex number.
Option 4 -
is the real number not complex.
Therefore, Only option 3 is the complex number.
Answer:
4 hours
Step-by-step explanation:
In order to solve this problem, you need to write down the equation. The equation is 3 +8x=35. In this equation, x represents the number of hours. The coefficient is 8, and that represents the number of kilograms per hour. You subtract 3 from both sides to get 32. Next, we solve for x. Divide both sides by 8 to get x=4 hours.
Answer:
12.82 feet
Step-by-step explanation:
To find the length of a 46-degree arc of a circle with a radius of 10 feet, you can use the formula for finding the length of a circular arc:
Arc Length = (θ/360) * 2πr
Where:
θ is the central angle in degrees.
r is the radius of the circle.
In this case, θ = 46 degrees and r = 10 feet. Plug these values into the formula:
Arc Length = (46/360) * 2π * 10
Arc Length = (23/180) * π * 10
Arc Length ≈ 12.82 feet
So, the length of a 46-degree arc of a circle with a radius of 10 feet is approximately 12.82 feet.
