Answer:
( 0 < y < 23 / 6 ) mins
Step-by-step explanation:
Solution:-
We will define a variable ( x ) as the time it took for Jo Anne to give her speech at home.
The time taken to give her speech must always be less than 4 minutes. We can express this mathematically using an inequality as follows:
( 0 < x < 4 ) minutes
Jo Anne gave her speech which was 10 seconds less than the one she practised at home. We will convert the time in seconds to minutes as follows:

The time taken by Jo Anne to complete her speech in English class can be represented as:
y = x - 1/6
Using the range of time that Jo Anne could take in delivering her speech in the class would be:
0 < x < 4
0 - 1/6 < y < 4 - 1/6
-1/6 < y < 23 / 6
Since time can not be less than zero. We correct the lower limit to " 0 " as follows:
( 0 < y < 23 / 6 ) mins
Answer:
∠KNC = 99°
Step-by-step explanation:
∠JNM + ∠KNC = 180 (it is a straight line)
∠KNC = 180 - ∠JNM
∠KNC = 180 - 81
∠KNC = 99°
Answer:
ez Triangle is the answer
Answer:

Step-by-step explanation:
Given

Interval: (-2,4)
Required
Determine the average rate of change
This is calculated using:

Where:

So, we have:



Calculate g(4) and g(-2)


So:



<em>Hence, the average rate of change is 1</em>
There are 3 terms in this expression. You can determine this answer by knowing that terms are either a single number or variable or numbers and variables multiplied together. Here's a picture example below:
