Answer:
0.3. and 2
Step-by-step explanation:
For this equation: a=1, b=0.3333333333333333, c=0.8333333333333334
1x2+0.333333x+0.833333=0
Step 1: Use quadratic formula with a=1, b=0.3333333333333333, c=0.8333333333333334.
x=
−b±√b2−4ac
2a
x=
−(0.333333)±√(0.333333)2−4(1)(0.833333)
2(1)
x=
−0.3333333333333333±√−3.222222
2
i think this is right :)
Answer:
simplified is 6x-20
Step-by-step explanation:
Answer:
The function is nonlinear
Step-by-step explanation:
Given
x --- y
1 --- 6
2 --- 24
3 --- 54
4 --- 96
Required
Determine if the function is linear of not
A function is linear if the difference in the successive y values are the same for corresponding values of x
When x = 1; y = 6 and when x = 2; y = 24
When x = 2; y = 24 and when x = 3; y = 54
When x = 3; y = 54 and when x = 4; y = 96
Note that the calculated differences are not equal.
<em>Hence, the function is nonlinear</em>
Answer: See the Venn diagram below
Explanation:
The numbers 1, 2, and 6 are in both set X and set Y. These numbers go in the overlapped region of the circles.
Since 1,2,6 is already taken care of, the remaining values in set X (3 and 8) will go in circle X, but outside circle Y.
The value 5 goes in circle Y, but it's outside circle X.
So far we talked about the numbers 1,2,3,5,6,8. But we're missing 4 and 7. These numbers go outside both circles. Everything is inside the universal set, i.e. the rectangle.
Ground: y = 0
- 16t² + 128t + 50 = 0
Apply quadratic equation.
t = 0, 8 (rounded to the nearest second)
