There are no real numbers that can do that job.
There's a pair of complex numbers that can do it.
They are
5.5 + i4.97
and
5.5 - i4.97 .
' i ' = the imaginary unit = √(-1)

Answer:
To solve for the zeros of the function equate f(x) = 0
That's
- 2x² + x + 5 = 0
Using the quadratic formula
a = - 2 b = 1 c = 5
And from the question
b² - 4ac = 41
So we have
We have the final answer as
Hope this helps you
Answer:
15.66
Step-by-step explanation:
2.7 x 11.6/2 is your answer
Answer: 30
Step-by-step explanation:
If you notice that multiplying by 0.5 is the same as dividing by 2, all you need to do is multiply 18 by 2, giving you 36, then subtract 6 from that, therefore giving you 30 as the answer
Correct.
The number 0.0090 has two significant figures in it, as we can represent the placeholder zeros (the ones between the decimal and the first 'significant' number - in this case, the 9) with a power of ten: 9.0x10^-3. Additionally, it is a measured number, meaning whatever instrument was used to measure displayed the zero in the ten thousandths place.
The number 87.10 has four significant figures. There are no placeholder zeros between the decimal and a 'significant' number, and it is also a measurement made by an instrument which displayed a zero in the hundredths place.
When numbers are multiplied or divided, the answer should be rounded to the same number of significant figures as the value with the least number of sig figs in the calculation.
0.0090 x 87.10 = 0.7839
= 0.78 rounded to 2 sig figs
or
7.8 x 10^-1 in scientific notation
