Answer:
B: 5.6 x 10 to the 12th power.
Step-by-step explanation:
8* 10^7 * 7* 10^4
Multiply the first terms and add the powers of 10
56 * 10 ^(7+4)
56. * 10 ^11
This is not proper scientific notation
We can only have one number in front of the decimal. We have to move the decimal one place to the left, which means we add one to the exponent
5.6 * 10^ (11+1)
5.6 * 10^12
Answer:
a) 1.24 g/ml
b) 2.4%
Step-by-step explanation:
density = mass/volume
volume of sample = 28.4 - 15 = 13.4mL
density = 13.4/10.8
=1.24 g/ml
percent error
1.27 - 1.24 = 0.03
0.03/1.24 *100% = 2.4% error

x < 14
x > −14
x < −14
The required solution to the given inequality is x < -14. which is the correct answer would be an option (D).
Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.
To solve the inequality x − 2 > 2x + 12, we first need to isolate the x-term on one side of the inequality. We can do this by adding 2 to both sides, which gives us:
x − 2 + 2 > 2x + 12 + 2
x > 2x + 14
Then, we can subtract 2x from both sides to isolate the x-term on the left-hand side:
x - 2x > 2x + 14 - 2x
-x > 14
Finally, we can divide both sides by -1 to get x < -14.
Therefore, the required solution to the given inequality is x < -14.

The given logarithm is
Recall that the common logarithm has a base of 10.
Recall also that;
Answer: Here's my answer
Step-by-step explanation:
The given information can be written as:
1. X^2 + k + l = 5x - 6
2. kl = 5x - 6
3. jk = 3x
Let's break it down step by step and analyze each equation:
1. X^2 + k + l = 5x - 6: This equation represents a quadratic equation, as it contains the term X^2. It relates the variables X, k, and l to the expression 5x - 6. To solve this equation, we would need additional information or constraints.
2. kl = 5x - 6: This equation shows that the product of k and l is equal to 5x - 6. It relates the variables k, l, and x. However, without specific values or constraints, we cannot determine the exact values of k, l, or x.
3. jk = 3x: This equation relates the variables j, k, and x. It states that the product of j and k is equal to 3x. Similarly to the previous equation, we need additional information or constraints to find specific values for j, k, or x.
In summary, the given equations represent relationships between different variables (X, k, l, j, and x), but without further information or constraints, we cannot solve them for specific values. It is important to have additional context or equations to determine the values of the variables or to find a specific solution.
