Answer:
I'm pretty sure that it's -i
For this case we have the following equation:
sin (40o) = b / 20
Clearing b we have:
20 * sin (40o) = b
Therefore, the length of the AC segment is given by:
b = 12.9
Answer:
the length of AC is:
b = 12.9
4.16 hours and 4 cups
Step-by-step explanation:
10. To find the % of something simply turn 5/6 in to a decimal (.83) then times it by the number you want .83 * 60 = 50 so its about 50 min each class, just times it by 5 =250 and lastly divide it by 60 for hours <u>4.16</u>
11. Simply times it by 6, 2/3*6= <u>4</u><u> </u><u>c</u><u>u</u><u>p</u><u>s</u>
Answer:
the negative exponent means that the decimal move to the left so the answer is 0.000025.
Step-by-step explanation:
2.5--->0.000025
For this case we have the following function:
we have:
Where:
By definition, the discriminant of a quadratic equation is given by:
Two different real roots
Two equal real roots
: Two different complex roots
Substituting the values we have:
We have two equal real roots.
To find the intersections with the x axis, we do 
We apply the quadratic formula:
Substituting the values we have:
The intersection with the x axis is
Answer:
The intersection with the x axis is
