The following are the answers to
the questions presented:
Part 1:
Vertex: <span>(<span><span>−3</span>/ 2</span>,<span> 11/2</span>)</span>
Axis of
symmetry = x = -3/2
Domain = all
real numbers
Range = <span>y </span><span>≤ </span>11/2
Part 2:
A quadratic equation is symmetrical around its vertex. The
equation for the axis of symmetry is x = -3/2 since the equation is in terms of
x. Since no value of x is undefined, then the domain of the equation is clearly
all real numbers. Since the value of “a” is negative, then that means the y
coordinate of the vertex is the maximum value so the range will never get above
11/2. I am hoping that these answers have satisfied your queries and it
will be able to help you in your endeavors, and if you would like, feel free to
ask another question.
Answer:
$10452958
Step-by-step explanation:
Initial profit = $11900848
Fall rate= $48263 per year
Equation:
- P(x)= 11900848 - (x-1990)*48263,
where P(x)= profit at year of x, and 1990<x<2020
- P(2020)= 11900848- 30*48263= $10452958
Answer:
= $3,888.89
Step-by-step explanation:
First, calculate the money multiplier(MM); which is the amount of money that is generated by the banks for each dollar of reserve. In this case, it describes how a deposited amount increases the total supply of money.
Money Multiplier = 1 / reserve ratio
Reserve ratio = 9% or 0.09
Therefore, money multiplier = 1/0.09 = 11.1111
Next, use the reserve ratio to calculate the amount of increase in money supply;
= 11.1111 * $350
= $3,888.89
Answer: First option
12 candy bars were sold
Step-by-step explanation:
Call x the amount of candy sold and call z the amount of cookies sold. Then we know that
We also know that candy bars sell for $ 3 and cookies sell for $ 5. The profit was $ 76
So:
To find the quantity of candy bars sold we must solve the system of equations:
Multiply the first equation by -5 and add it to the second equation
+
