Answer:
Inflation is the continuing reduction of the purchasing power or price level rise in a given time period.
Therefore, keeping money in a savings account that gives an interest rate that is lower than the inflation rate, in a period of high inflation will result in a reduction of the purchasing power of the amount of money plus interest in the savings account.
If the interest rate is 10%, the amount, A, in the account after a given time will be 1.1A
If the inflation rate is 15%, the value of the goods sold initially at A, will become 1.15A after the given period and the amount in the account will no longer be able to purchase the goods it was initially able to purchase, or the amount in the savings account will lose value
Step-by-step explanation:
The correct answer is option D which is the second coordinate of the vertex of the quadratic function that represents the maximum height of the baseball.
<h3>What is a quadratic equation?</h3>
The polynomial having a degree of two or the maximum power of the variable in a polynomial will be 2 is defined as the quadratic equation and it will cut two intercepts on the graph at the x-axis.
The second coordinate of the vertex of the quadratic function represents the maximum height of the ball.
The height of a baseball hit from a bat is modeled by a quadratic function of time, h(t)
General form of h(t) will be -16x² + v(t) + h
Where v represents initial velocity and h represents the initial height
h(t) represents the height of the baseball
h(t) is negative so the height reaches the maximum
vertex (h,k) represents maximum height (k) when time t=h
So the second coordinate of the vertex of the quadratic function represents the maximum height of the ball.

Answer:
-4 and -10
Step-by-step explanation:
-4 * -10 = 40 because two negatives multiplied equals a positive.
-4 + -10 = -14 because when two negatives added together, you get a negative.
Answer: 12
Step-by-step explanation:
1 1/4 + 3/4 = 2
1 1/2 - 1 1/3 = 1/6
= 12
