Answer:
98
Step-by-step explanation:
Step 1: Define
2(x + y)²
x = 3
y = 4
Step 2: Substitute and Evaluate
2(3 + 4)²
2(7)²
2(49)
98
Answer:
1. Rotate DEF 90 degrees clockwise about point D (8,1).
2. Translate DEF 8 units up.
3. Reflect DEF about the line x = 6.5.
Step-by-step explanation:
Sample answer for PLATO!
You would have to solve this by Lxwxh.
25.4*19.05*76.2= 36870.89 centimeters
1 in= 2.54 centimeters
36870.89 centimeters*1 in/2.54 centimeters= 14516.09843 inches.
I hope this is helpful :)
Answer:
rotation
Step-by-step explanation:
"Isometric" means all measures stay the same.
- dilation changes all lengths
- <em>rotation changes no measures -- an isometric transformation</em>
- side length change obviously changes the length of a side
- angle change obviously changes the measure of an angle
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
