To multiply these numbers, the first step is to writhe "-8" as an improper fraction, to do so, divide it by 1
Next is to solve the multiplication, to do so, first multiply the first two terms of the multiplication:
The multiplication is between two negative numbers, when you multiply two negative numbers, the minus signs cancel each other and turn into a positive value, this is called "double-negative"
Next multiply the result by the third fraction -2/5
This time you are multiplying a positive and a negative number, so the result of the calculation will be negative
Final step is to simplify the result, both 144 and 15 are divisible by 3, so divide the numerator and denominator by 3 to simplify the result to the simplest form:
Answer:
Step-by-step explanation:
Let the quadratic function be
The given points must satisfy this function;
Substitute 
.
Substitute (0,-2)
Substitute (1,-4);
Put equation (2) into equation (1)
Put equation (2) into equation (3)
Add equation (4) and (5)
Divide both sides by 3
Put a=3 in equation 5.
The quadratic function is;
Answer:
It is after 4 explorations that the submarine's elevation would have changed by -3/2 miles
Step-by-step explanation:
From the question,
The elevation of the submarine changes by -3/8 mile after each exploration.
To determine the number of explorations it will take for the submarine's elevation to have changed by -3/2 miles, we will divide -3/2 miles by the number of miles the elevation of the submarine changes per exploration (that is, -3/8 mile),
That is,
-3/2 miles ÷ -3/8 mile
= 
= 
=
= 4
Hence, it is after 4 explorations that the submarine's elevation would have changed by -3/2 miles.
