If you mean getting a 2 on a dice then the answer would be
4/6 or 2/3
Answer: 2.66 × 10⁻¹³
<u>Step-by-step explanation:</u>
First, use the decay formula where
- A is the final amount (amount left)
- A₀ is the initial amount (amount you started with)
- k is the rate of decay (you need to solve for this)
- t is the time
Given:
- A = 1/2(300) = 150
- A₀ = 300
- k = unknown
- t = 28.8
Next, input the k-value and the new t-value to solve for A.
- A = unknown
- A₀ = 300
- k = -0.0240676
- t = 1440
Answer:
Step-by-step explanation:
- Temperature drop = - 1.6°C / hr
- Time = 4 1/4 hr
<u>Temperature change is:</u>
- -1.6 * 4 1/4 =
- -1.6 * 4.25 =
- - 6.8°C
You can translate to:
F ÷ 28 = 24
F/28 = 24 Cross Multiply
F = 28 * 24
F = 672
Answer:
9
Step-by-step explanation:
Since the axis of symmetry is vertical and the vertex of the parabola is at (12,-4), the vertical line x=12 is the axis of symmertry. The x-distance between the axis of symmetry and the first x intercept (15,0) is equal to 15-12=3. Hence, this x-intercept is 3 units to the right of the axis, and because it is symmetric, the other x-intercept must be 3 units to the left of the axis, so its x-coordinate must be 12-3=9. Then, the other x-intercept is at the point (9,0)
