Answer:
Step-by-step explanation:
The time constant of the isotope is:
The decay of the isotope is described by the following model:
Now, the time is cleared in the equation:
No because you are distributing and for 3(x+11/2), you multiply 3 times x is 3x and then 3 times 11/2 is 16 1/2 . All together 3x+16 1/2 or 16.5
It is not equal to 3x+11/2.
Answer:
Option C
Step-by-step explanation:
From the picture attached,
Given:
SE ≅ EP
∠ESA ≅ ∠ EPN
To Prove:
ΔSEA ≅ ΔPEN
Solution:
Statements Reasons
1). SE ≅ EP 1). Given
2). ∠ESA ≅ ∠ EPN 2). Given
3). ∠SEA ≅ ∠NEP 3). Vertical angles theorem
4). ΔSEA ≅ ΔPEN 4). By ASA postulate
Therefore, Option C is the correct option.
Answer:
<h3>Question 1</h3>
<u>Function given:</u>
<u>In the vertex form:</u>
- y = x² + 4x + 4 - 8 = (x + 2)² - 8
Axis of symmetry is the vertical line passing through the vertex.
<u>The vertex is</u>
<u>Axis of symmetry is </u>
<u>y- intercept is </u>
- x = 0 ⇒ y = -4, so the point (0, -4)
<u>Two other points are</u>
- x = 1 ⇒ y = (1 + 2)² - 8 = 9 - 8 = 1, the point is (1, 1)
- x = -1 ⇒ y = (-1 + 2)² - 8 = 1 - 8 = -7, the point is (-1, -7)
<em>See the graph with all the points plotted</em>
<h3>Question 2</h3>
<u>Function given:</u>
<u>In standard form:</u>
<u>In vertex form:</u>
- y = - 2x² + 4x - 2 + 8 = -2(x - 1)² + 8
<u>The vertex:</u>
<u>Axis of symmetry is </u>
<u>y - intercept </u>
- x = 0 ⇒ y = -2(-1)² + 8 = -2 + 8 = 6, the point is (0, 6)
<u>Two other pints:</u>
- x = -1 ⇒ y = -2(-1 - 1)² + 8 = -8 + 8 = 0, the point is (-1, 0)
- x = 2 ⇒ y = -2(2 - 1)² + 8 = -2 + 8 = 6, the point is (2, 6)
<em>The graph is attached with the points plotted.</em>
The answer is 40 because once you have 21 your just adding 19 and then that makes it 40.
