Answer: 20% increase
Step-by-step explanation:
Think about it this way 1/5 of 100 is 20. 1/5 of 15 is 3. So 15+3=18
You can use zero as a starting point and then plot based on the direction of your number, so say you have a -1. You would plot that -1 to the left of 0 and any other negative numbers you have. Regarding positive numbers, they would all go to the right of zero so if you had to plot +1 you would plot that to the right of zero. I attached a photo to help you :)
Answer:
Domain: [0,∞)
Range: (-∞, 4]
Step-by-step explanation:
Answer: The other root of the given polynomial equation is a - bi, because complex roots always occur in conjugate pairs.
Step-by-step explanation: Given that a quadratic polynomial equation with real coefficients has a complex solution of the form a + bi with b ≠ 0.
We are given to find the a number that must be the other solution with reason.
We know that the complex roots of a quadratic equation always occur in conjugate pairs. That is,
if x + yi is one of the roots of a quadratic equation, then its conjugate x - yi is the other root of the equation.
According to this, we can say that the other root of the given quadratic polynomial is a - bi.
Thus, the other root of the given polynomial equation is a - bi, because complex roots always occur in conjugate pairs.
Answer:
Circumference = πd
where d = diameter
Step-by-step explanation:
When using this formula you don't need to multiply by 2 like you do when using the radius because the diameter is twice the radius of a circle.
