Image of A (2-8, 6+4) =(-6,10)
image of B (-1-8, 5+4)=(-9,9)
Answer:
<h2><u><em>
Area = x² + 8x + 12</em></u></h2><h2><u><em>
Perimeter = 4x + 16</em></u></h2>
Step-by-step explanation:
The area of a rectangle is given by the formula:
Area=width×height
The perimeter of a rectangle is given by the formula
Perimeter=2(width+height)
Area
(x + 6) × (x+2) =
x² + 2x + 6x + 12
x² + 8x + 12
------------------
Perimeter
2 × (x + 6 + x + 2) =
2 × (2x + 8) =
4x + 16
Answer:
0.108
Step-by-step explanation:
0.66 × 0.33 × 0.5 = 0.108.
Formula: L × W × H × 1/6.
L = 4
W = 2
H = 3
4×2×3.
We then have you multiply that by 1/6.
4×1/6 = 0.66.
2×1/6 = 0.33
3×1/6 = 0.5
0.66 × 0.33 × 0.5 = 0.108.
Now, onto the correct answers.
7) (4×1/6cm) × (2×1/6cm) × (3×1/6cm)
7 is correct, because the answer is diving each number by 1/6, and multiplying them with each other.
1) 1/216 × 24
1 is correct, because the answer when the question is evaluated is around 0.108. 1/216 × 24 = 0.11111111111. It is very close to the answer. This, indeed is correct.
Answer:what happened to c and a
Step-by-step explanation:
The pH of the weak acid is 3.21
Butyric acid is known as a weak acid, we need the concentration of [H+] formula of weak acid which is given by this equation :
![[H^{+}]=\sqrt{Ka . Ma}](https://tex.z-dn.net/?f=%5BH%5E%7B%2B%7D%5D%3D%5Csqrt%7BKa%20.%20Ma%7D)
where [H+] is the concentration of ion H+, Ka is the weak acid ionization constant, and Ma is the acid concentration.
Since we know the concentration of H+, the pH can be calculated by using
pH = -log[H+]
From question above, we know that :
Ma = 0.0250M
Ka = 1.5 x 10¯⁵
By using the equation, we can determine the concentration of [H+]
[H+] = √(Ka . Ma)
[H+] = √(1.5 x 10¯⁵ . 0.0250)
[H+] = 6.12 x 10¯⁴ M
Substituting the value of [H+] to get the pH
pH = -log[H+]
pH = -log(6.12 x 10¯⁴)
pH = 3.21
Hence, the pH of the weak acid c3h7cooh is 3.21
