What is the discriminant: 2x^2 + 3x + 10=0

Mathematics

The discriminant of a quadratic equation is:

b^2-4ac

Plug in the values. 

3^2-4(2)(10)

=9-80

=-71 

Since the discriminant is negative, you can tell that the quadratic has no real solutions. 

Hope that helped!

Question :
<span>What is the discriminant: 2x^2 + 3x + 10=0
</span>Answer :
from the matter we know that :
a = 2
b = 3
c = 10

discriminant formula is :
b^{2}-4ac

= 3^{2}-4(2) \times 10

= 9-8 \times 10

= 9-80

= -71

Answer:

B

Step-by-step explanation:

Help geometry what I m jlf <br> Picture provided
Zolol [24]

Answer:

\angle\,JLF = 114^o  which agrees with option"B" of the possible answers listed

Step-by-step explanation:

Notice that in order to solve this problem  (find angle JLF) , we need to find the value of the angle defined by JLG and subtract it from 180^o, since they are supplementary angles. So we focus on such, and start by drawing the radii that connects the center of the circle (point "O") to points G and H, in order to observe the central angles that are given to us as 90^o and 138^o. (see attached image)

We put our efforts into solving the right angle triangle denoted with green borders.

Notice as well, that the triangle JOH that is formed with the two radii and the segment that joins point J to point G, is an isosceles triangle, and therefore the two angles opposite to these equal radius sides, must be equal. We see that angle JOH can be calculated by : 360^o-90^o-138^o=132^o

Therefore, the two equal acute angles in the triangle JOH should add to:

180^o-132^o=48^o resulting then in each small acute angle of measure 24^o.

Now referring to the green sided right angle triangle we can find find angle JLG, using: 180^o-24^o-90^o=66^o

Finally, the requested measure of angle JLF is obtained via: 180^o-66^o=114^o

How many hours will it take to complete a 76km bike ride if you go bike ride if you go 14km per hour the whole time?
soldi70 [24.7K]

To find the number of hours, divide the total distance by the speed.

Hours = 76 km / 14 km per hour

Hours = 4.529

Round the answer as needed.
