Answer:
4,415.1515...
Step-by-step explanation:
To find the value of the number that 1457 is 33% of, we can change the percentage into a decimal then divide.
33% = 0.33
1457 / 0.33 = 4,415.1515...
Best of Luck!
Answer:
Completing the square. I mean, you can, for some values of a and b, but it's not going to help much if it is messy. Nope!
Factoring. Yes. It's really easy since there is an obvious common factor.
Square root theorem. No idea what this is. And I don't know how it would help.
Quadratic equation. This works, but is a little long for what you have to do.\
To solve this equation , we need to write it in quadratic form
To get the equation in quadratic form we replace x^2 with u
can be written as
, Replace u for x^2
So equation becomes
Now we factor the left hand side
-16 and -1 are the two factors whose product is +16 and sum is -17
(u-16) (u-1) = 0
u -16 = 0 so u=16
u-1 =0 so u=1
WE assume u = x^2, Now we replace u with x^2
Now take square root on both sides , x= +4 and x=-4
Now take square root on both sides , x= +1 and x=-1
So zeros of the function are -4, -1, 1, 4
Answer:
s = 1.35 (See explanation!)
Step-by-step explanation:
To write an equation, you need to know that all four sides of a square are equal. Since each side is equal, it can be represented by the same variable or value. I'll use s for the variable:
Equation:
4s = 5.4
Note: the 4s is the total perimeter (4 * side)
Now, solve:
4s = 5.4
Divide by four to isolate the s:
4s/4 = 5.4/4
Finally:
s = 1.35
