A(n) = 1 + (n - 1)(-4.1)
a(1) = 1 + (1 - 1)(-4.1) = 1
a(4) = 1 + (4 - 1)(-4.1) = 1+(3)(-4.1)=1 - 12.3 = -11.3
a(10) = 1 + (10 - 1)(-4.1) = 1 + (9)(-4.1) = 1 - 36.9 = -35.9
The initial height of the ball is the y-intercept of the function
The initial height she threw the ball from is 35
<h3>How to determine the initial height</h3>
The function is given as:

Set x = 0.
So, we have:

Evaluate the exponent

Evaluate the products

Evaluate the sum

Hence, the initial height she threw the ball from is 35

Answer:
approximately 42.05
Step-by-step explanation:
We know that the distance formula is
, so if we use (3,8) as point 2 and (21, -30) as point 1 (note that these are interchangeable), we know that
x₂=3
y₂=8
x₁=21
y₁=-30
Then, we can plug it into the formula to get 
To the nearest whole number it would be 35
Step-by-step explanation:
Answer:
B. all whole integers
Step-by-step explanation:
the question and x is talking about people, meaning that people cannot be decimals"" , so its b
