We know that imaginary roots always come in pairs, so we already know 4 solutions
-2, 2, 4 + i and a pair of 4 + i
Since imaginary roots always come in pairs we wont have more than 2 imaginary roots, since its a fifth degree root and we can only have 5 roots
So for sure, we will have 3 real roots and 2 imaginary roots
Last option, f(x) has three real roots and two imaginary roots
No, since it is absolute value. The answer would simply be 5, since 5 - 10 is in the absolute value bars.
Answer:
cos A=

Step-by-step explanation:
We know,
cotA=

Substituting the value of cot A in the given equation, we get











The width of a rectangle is going to be equal on both sides, as they’re parallel in a rectangular shape. We know the width is 86 yards, and we have two lots of these, therefore 86 multiplied by 2 is equal to 172 yards.
We still have two more sides, but once again, because this is a rectangle, those sides must be equal. Therefore if we subtract the 172 yards we know from the total perimeter of 438 yards we will end up with an answer of 266 yards. This figure is divided by two because we have a length on either side of the perimeter. Therefore the answer is 133 yards.
Hope this helps!
Answer:
The cost would be 22.75
Step-by-step explanation:
To find the cost of each topping, we simply take the excess cost and divide it by the number of toppings. To find the excess cost, take the new cost and subtract the original cost.
17.50 - 14.00 = 3.50
Now divide that by the amount of toppings.
3.50/2 = 1.75
Now we can multiply the new number of toppings by that amount and add the cost of the pizza.
5(1.75) + 14.00
8.75 + 14.00
22.75
