The standard form of an imaginary number is <span>a ± bi where a is the real number and b is the imaginary number. The answer hence is false. i related to an imaginary number is equal to square root of -1. Hence when i is squared, the answer should be -1. Answer is false. Complex numbers can be graphed only in an plane with an imaginary axis and a real axis/ Answer in 3 is false</span>

Answer.
1) False
2) False
3) False

Explanation
1) When a number is written as a+bi, a and b are real number. b is never considered as imaginary number.
The statement given is false.


2) The value of i is √(-1), when squared we get;

(√(-1))² = -1.
The answer given is false.

3) It is not possible to graph a complex number is XY coordinates. Complex number are graphed on an imaginary axis and real axis only. 
The statement given is false.

The function f(t)=-16 + 100 models the height of a ball, in feet, dropped from a 100-foot rooftop at time t, in seconds.
Mazyrski [523]

Using it's concept, it is found that the average rate of change of the function during the interval from 0 to 2 seconds is given by:

B. -32 ft/s; the average change in altitude of the ball each second over that interval.

<h3>What is the average rate of change of a function?</h3>

The average rate of change of a function is given by the change in the output divided by the change in the input. Hence, over an interval [a,b], the rate is given as follows:

r = \frac{f(b) - f(a)}{b - a}

In this problem, the function is given by:

f(t) = -16t² + 100.

The outputs are given as follows:

  • f(0) = -16(0)² + 100 = 100.
  • f(0) = -16(2)² + 100 = 36.

Hence the average rate of change is given by:

r = (36 - 100)/(2 - 0) = -32 ft/s.

And the correct option is:

B. -32 ft/s; the average change in altitude of the ball each second over that interval.

Explain why this statement is true:<br> 7a +4 – 2a = 7a + (-20)+4
MAVERICK [17]

Answer:

This equation has one solution so given statement is true.

Step-by-step explanation:

7a +4 – 2a = 7a + (-20)+4

5a + 4 = 7a - 16

5a - 7a = -16 - 4

- 2a = - 20

a = 10

This equation has one solution so given statement is true.
