Since multiplying by 0.5 is the same as dividing by 2, the problem is described by the sentence
"Half the sum of a number and 40 equals 200"
10^12 in standard number is 1000000000000
<h3>How to convert the number?</h3>
The number is given as:

Expand the expression

Evaluate the product

Hence, 10^12 in standard number is 1000000000000

So... let's say, we have two numbers "a" and "b",
"a" is the smaller one, "b" is the larger one
so, their sum is 6
a + b = 6
3 times the smaller => 3 * a or 3a
now, two less than that
3a - 2
that equals the larger "b"
3a - 2 = b
solve for "a",
now, what's "b"? well, 3a - 2 = b :)
Answer:
Domain: all real numbers
The interval on which the function is increasing is : (0 , infinity)
The interval on which the function is decreasing is : (-infinity , 0)
The interval on which the function is constant is : ( 0,0 )
Step-by-step explanation:
f(r)=5r^2−4
This is a quadratic function.
vertex at (0, -4) and with positive coefficient for r^2
The interval on which the function is increasing is : (0 , infinity)
The interval on which the function is decreasing is : (-infinity , 0)
The interval on which the function is constant is : ( 0,0 )
