Lets get started :)
We need to isolate t from x =
at²
Take 2 to the left-hand side { Do multiplication since you see division }
2x = at²
Take a to the left-hand side { Do division since you see multiplication }
= t²
Take square root since t is to the power of 2
= t
Answer: 98%
Step-by-step explanation:
First subtract the birth weight from the new weight (890-450=440). To find what percent of 450 that is, divide the difference by 450 (440/450=97.78). Round to the nearest whole number (97.78==>98).
Answer:
See below
Step-by-step explanation:
if b^2 - 4ac is greater than 0 then there are 2 answers that are not equal to each other, but both are real.
If b^2 - 4ac = 0 then you have two real answers that are equal
The real problem is what happens when b^2 - 4ac is less than 0? In this case the answer is a complex number of the form
a + bi
a - bi
where i is the square root of - 1
The given equation is
To solve for x, we have to subtract 8 to both sides
Now we need to get rid of -9 from the left side, and for that we do division
Answer:
Square numbers
Step-by-step explanation:
if 1 is squared, you get 1.
if 2 is squared, you get 4.
if 3 is squared, you get 9.
if 4 is squared, you get 16.
And thus square numbers.
