Maybe because you're finding the "difference" between the two numbers. We could also question why the answer to an addition problem is called sum.
Well, 'sum'body said that's what they should be called a long time ago, that's why we're using that term to call them now.

=sqrt(11316)

=106.3766 feet

=106.38

= 2. Given the quadratic equation 3x2 – 8x + k = 0 has no real roots. Find the range of values of k.

VashaNatasha [74]

$\text{If there are no real roots, then}\\\\~~~~~\text{Discriminant} < 0\\\\\implies b^2 -4ac < 0\\\\\implies (-8)^2 -4 \cdot 3 k < 0\\\\\implies 64-12k < 0\\\\\ \implies 12k > 64\\\\\implies k > \dfrac{64}{12}\\\\\implies k > \dfrac{16}3\\\\\text{Interval,}~ \left( \dfrac{16}3, ~\infty\right)$

Convert “6750.” into scientific notation

Sophie [7]

Answer:

6.75 × 10^3

Step-by-step explanation:

Move the decimal 3 times to the left so that the resulting number, m = 6.75, is greater than or equal to 1 but less than 10

Since we moved the decimal to the left the exponent n is positive

n = 3

Write in the scientific notation form, m × 10^n

6.75 × 10^3
