<u>Answer</u>
2. 40
<u>Explanation</u>
The angle subtended by the diameter to the circumference is equal to 90°.
∴ angle ABC = 90°
Angles in a triangle = 180°
50 + 90 + x = 180
90 + x = 180
x = 180 - 90
= 90°
Since the variable x is at the exponent, this is an exponential function.
To decide whether an exponential function is a growing or decaying one, we have to look at the base of the exponent.
If the base is between 0 and 1, we have exponential decay
If the base is larger than 1, we have exponential growth.
In your case the base is 3, which is larger than 1, so you have exponential growth.
Thus, <u>option d</u> is your answer
Answer: Choice B) she is not correct; the exponent should be 6
I'm assuming you meant to say 1.5006 x 10^4
The exponent 4 means we move the decimal point four spots to the right to go from 1.5006 to 15,006
This result is a little over 15 thousand when we want closer to 1.5 million
The exponent should be 6. We move the decimal point six places to the right to go from 1.5006 to 1,500,600 which is the proper value we want
So Sarah should have written 1.5006 x 10^6
