Answer:
0
Step-by-step explanation:
It is been considered that Discriminant is calculated by the following formula:
D = b*b - 4 * a * c
In order to simplify the calculations we can divide all the numbers by 2 and we will have the same quadratic equation:
-x^2 -4x+4=0
and as usual quadratic equation is presented as the following:
ax^2 - bx + c = 0
so in our case a = -1; b = -4; c = 4;
Then D = -4*4 -4*(-1) * 4 = -16+16 = 0
I am not quite understanding the following phrase:
"and what does it value mean about the number about the number"
but if the question was in regards of the following number '-2x^2' so number ^2 is actually the value of power so 'x' is multiplied on it is own and this equation basically means the following:
-2x^2 = -2 * (x) * (x)
Answer:
38.2842 m
Step-by-step explanation:
The acceleration is given by ...
a = ∆v/∆t
and the distance traveled is given by ...
d = 1/2at^2
So the distance we're looking for is ...
d = (1/2)(21.0366 m/s)/(8.06 s)(5.41632 s)^2 = 32.2842 m
This would be 400%. To get a percent you multiply the number by 100. For example, .62 x 100 equals 62%.
(a) With a unit rate of 8, repeated (iterated) 72 times, we can simply multiply 8 by 72 to get the net change: 8 × 72 = 576 fish.
(b) For the unit rate (i.e. rate of change per time - minutes in this case) we can simply divide the total water pumped out by the total time it took to perform this. So: 48 ÷ 8 = 6 gallons/min.
Hope I could help you! :)
Answer:
35%
Step-by-step explanation:
1. Multiply 78.75 by 100
78.75* 100 = 7875
2. Divide this by 225
7875/225 = 35
3. Make this number a precent 35%
