Answer:
3
Step-by-step explanation:
all numbers except from zero
that would mean 7 4 and 3
so there would be 3 significant figures
I hope it goes well
Answer:
The solutions are 
and 
Step-by-step explanation:
we have
Divide by 
both sides
------> 
we know that
The formula to solve a quadratic equation of the form 
is equal to
in this problem we have
so
substitute
Let one of the numbers be x. The other number cab then be represented as 36-x (x+36-x = 36).
The product can then be represented as y = x(36-x) or y=36x-x2
The maximum or minimum is always on the axis of symmetry which has the formula x=-b/2a.
In our case, the axis of symmetry is -36/-2, so x=18.
If one number is 18 and the 2 numbers add to 36, the other number is 18 as well.
So the 2 numbers are 18 and 18 and the maximum product is 324,
10 because x+x = 20
a+b=c
Answer:
7740° / 45
Step-by-step explanation:
The sum of the interior angles is given by this formula: (n - 2) * 180°. So a regular 45-gon would have interior angles that add up to: (45 - 2) * 180°. = 43 * 180°. = 7740°. Now divide that by the 45 angles to find the measure of one interior angle
hope that helped :(
