Answer:
The distance between the givens points is 9 unit
Step-by-step explanation:
Given points are as :
A = ( 1 , 5 )
B = ( 1 , - 4 )
So, The Distance between points A and B = AB
Now, From Distance formula
AB =
Or, AB =
Or, AB =
Or, AB = = 9
Hence The distance between the givens points is 9 unit Answer
The density of a substance is the ratio of its mass and its volume. The mass of the rod is 10,666.67 grams or 10.67 kgs.
<h3>What is the density of a substance?</h3>The density of a substance is the ratio of its mass and its volume. Therefore we can write,
mass of substance = m kg
density of substance = d kg/m³
volume of that substance = v m³
The length of the rod is 4 meters, therefore, the length of the rod in centimeters will be 400 centimeters. Thus, The mass in terms of density can be written as,
Hence, the mass of the rod is 10,666.67 grams or 10.67 kgs.

If you move the decimal point left until it is just to the right of the most-significant digit, the number of places you moved it is the power of ten that your new number is multiplied by.
Then multiplication can proceed in the usual way, taking into account the rules of exponents.
Answer:
Step-by-step explanation:
Set g(x)=y
y=-2/5x+3
5y=-2x+3
2x=3-5y
x=3-5y/2
So g^-1(x)=
