Answer:
zero, because the discriminant is negative
Step-by-step explanation:
By writing the quadratic formula, we have the discriminant written in the root as;
b^2-4ac
Now, given the expression, we can see that the discriminant here is -19
What this mean is that we have a negative discriminant
Hence, we can conclude that the roots are complex and as such, none of the roots are real

Answer:
m∠BPD = 120
mBC + mAD = 120°
Step-by-step explanation:
according to intersecting chord theorem: The measure of the angle formed by two chords that intersect inside the circle is the sum of the chords' intercepted arcs.
m∠BPD = (M∠BD + M∠CA)
= (70 + 170)
= (240)
m∠BPD = 120
We know that a circle has a total of 360° around the center of circle. To find the measure of the remaining measure of angle of arcs, subtract them from the whole that is 360°
mBC + mAD = 360 - ( 70 + 170 )
= 360 - 240
mBC + mAD = 120°
Hi there! The answer is y = 1/6x + 1/2
To find the inverse function x and y need to switch places.
Now rewrite the equation, until it will be in standard form (slope-intercept form) again.
Add 3.
Switch sides.
Divide both sides by 6.
Hence, the answer is y = 1/6x + 1/2.
~ Hope this helps you!
Answer:
Answer is 11.89
Step-by-step explanation:
Let the missing number be w
9w < 31 = 3318
9w × 31 = 3318
9w = 3318\31
9w = 107.03
divide both sides by 9
9w\9 = 107.03\9
w = 11.89
