Answer:
<u>(</u><u>-3.5, 2.3</u><u>)</u>
Step-by-step explanation:
Let the point P have coordinates : (x, y)
The line (from R to Q) is divided in the ratio :
Coordinates of :
Using section formula :
- x = mx₂ + nx₁ / m + n
- x = 5(-5) + 1(4) / 5 + 1
- x = -21/6 = -7/2
- x = -3.5
- y = my₂ + ny₁ / m + n
- y = 5(3) + 1(-1) / 5 + 1
- y = 14/6 = 7/3
- y = 2.3
The coordinates of the point P are : <u>(</u><u>-3.5, 2.3</u><u>)</u>
Vertex is calculated by -b/2a
So we have -(-5)/2(2)=5/4
The root is determined through the quadratic formula:
x=(-b+sqrt(b^2-4ac))/2a
x=(-(-5)+sqrt(-5^2-4(2)(-604)))/2(2)
x=(5+sqrt(25-4832))/4
x=(5+sqrt(-4807))/4
So the root is some imaginary number
Hope this helped!
Answer:
y < 2 is the inequality of this graph
Step-by-step explanation:
That is exactly 8 half lives.
After 8 half - lives only (1 / 2^8) or (1 / 256) of the original 30 grams will remain.
(1 / 256) =
<span>
<span>
<span>
0.003906250
</span>
</span>
</span>
So, 30 * <span>
<span>
0.003906250 = </span></span>
<span>
<span>
<span>
0.1171875 grams will remain.
