Answer:
The value of
is
.
Step-by-step explanation:
We need to simplify the numeric expression using property. The expression is as follows :

The property to be used is : 
This property is valid if the base is same. Here, base is x.
In this given problem, x = 4, a = 1/3 and b = 1/5
So,

So, the value of
is
.
<u>Answer:</u>
The horizontal number line that could be used to show number of centimeters of ribbon Hilary unraveled is 3cm to 4.5cm
<u>Explanation:</u>
Given that Hilary has already unraveled 3.0 centimeters of ribbon and then continues to unravel 1.5 more.
So starting will be 3.0 cm and maximum ribbon unravelled will be equal to 4.5cm so the horizontal number line that could be used would be from 3cm to 4.5cm including both fractional and integral values.
Your answer is x={-1, 11/3}
The answer to the question
Answer:
Option A: For each increase of 1 gram in mass, A increases by approximately 0.3433 square centimeter.
Step-by-step explanation:
We are given the function;
A= 1321 + 0.3433m
To find the rate of increase of the area, we will find the derivative of the function. Thus;
dA/dm = 0.3433
This means that the area increases at the rate of 0.3433 Sq.metre for each additional 1 gram added to the mass.
Looking at the given options, the one that corresponds to our answer is Option A
