Answer:
discriminant: 241
2 real roots
Step-by-step explanation:
The discriminant is the part of the quadratic equation that is under the sqare root
x=(-b±√(b²-4ac))/2a
discriminant: b²-4ac
We also know that a quadratic equation is in the form ax²+bx+c = 0, so we can plug in the values we know from our equation to find the discriminant.
a=4
b=-17
c=3
(-17)^2-4(4)(3)
We also know that if the discriminant
is positive we have 2 real roots
is 0 we have 1 real root aka a repeated real solution
is negative we have no real roots
Answer:
0.085
Step-by-step explanation:
We know that 1/2=0.5. And to convert from percent to decimal you have to divide by 100.
Answer:
1/6.2
Step-by-step explanation:
1/(2+3 square root 2)
2+4.24264068712=6.24264068712
6.24264068712 Rounded to the nearest tenth is 6.2
1/6.2
Hope this helps.
$80 - $50 = $30
$30 * 100 / $ 80 = 37.5%
answer: 37.5% of decrease.
Find the total of the 3 CD's by multiplying 13.99 by 3:
13.99 x 3 = 41.97
Now add the tax:
41.97 x 1.04 = 43.65 ( total of 3 CD's with tax.)
Subtract the total of the CD's from the amount you have to find the change:
60 - 43.65 = 16.35
The answer is c. 16.35
