Answer:
Step-by-step explanation:
If you'd graph this function on a graphing calculator or graphing utility, you'd see quickly that the graph never touches or crosses the x-axis. This tells us immediately that there are no real roots; all four roots are complex or imaginary.
The answer is going to be 9300.
Answer:
48°
Step-by-step explanation:
We can solve this using our knowledge on tangents of an angle. Remember, tangents are the opposite leg divided by the leg adjacent to that angle.
This means the tangent of x° = 
. Now that we know the tangent ratio, we can find the angle with inverse trigonometric ratios. These kinds of ratios give us the opposite of the tangent - which would lead to the angle measure we're looking for. The equation would look like this:
Using a calculator, the answer would be:
Rounding this to the nearest degree would give us 48° as our answer! I hope this was clear enough.
98 is a composite number. 98 = 1 x 98, 2<span> x </span>49<span>, or </span>7<span> x </span>14<span>. Factors of 98: 1, </span>2<span>, </span>7<span>, </span>14<span>, </span>49<span>, 98. Prime factorization: 98 = </span>2<span> x </span>7<span> x </span>7<span>, which can also be written 98 = </span>2<span> x 7².</span>
