Sounds like a geometric progression. Initial value is $30,000; p is the annual increase, a percent, but expressed as a decimal fraction between 0 and 1; n is the number of years.
Total salary = $30,000 (1+p)^n, or, in shorthand and following the wording of this problem,
Total salary = $30,000 x^n, where x = 1 + p
A quadratic function is represented as ax² + bx + c. In this case, if you look at the coefficient of x, you'll see that b = -5.
Answer: Last option.
Step-by-step explanation:
Given the expression:

The Quotient of powers property states that:
And the Power of a powet property states that:
Then, applying these properties, you get:

Now you must remember that:
Therefore, simpliying the expression, you get:

Answer:
Value of equation = 26.25
Step-by-step explanation:
Given:
Equation given
-4a² + 3ab - (2a + 3b)
Given value of a = 1/4
Given value of b = -12
Find:
Value of equation
Computation:
-4a² + 3ab - (2a + 3b)
By putting value of a and b
-4(1/4)² + 3(1/4)(-12) - [2(1/4) + 3(-12)]
-4(1/16) - (36/4) - [2/4 - 36]
-4/16 - 36/4 - [-142/4]
- 0.25 - 9 + 142/4
-0.25 - 9 + 35.5
Value of equation = 26.25
Answer:factor of 9
Step-by-step explanation:
Given
prism were changed by a scale factor of 3
Suppose prism is rectangular in shape
So surface are is 
Where l=length
w=width
b=breadth
So new length,breadth and width is






So new surface area would change by a factor of 9
