8 more than half of n is 8 + n/2. That is c.
So,
c = n/2 + 8
or c = 8 + n/2.
The answer is a. 

hope this helps!! :)

Suzette deposited $800 into a bank account earning simple interest of 2.5% each year. After 5 years, how much interest had her a
Blababa [14]

Answer:

\boxed {\boxed {\sf \$ 100.00}}

Step-by-step explanation:

The formula for simple interest is

I=prt

where <em>p</em> is the principal, <em>r </em>is the rate, and <em>t</em> is the time.

The principal, or initial amount is $800 and the time is 5 years The interest rate is 2.5%, but we must convert to a decimal.

Divide by 100 or move the decimal place two spots to the left.

  • 2.5/100=0.025       or          2.5 ⇒  0.25 ⇒ 0.025

Substitute the known values into the formula.

p= 800 \\r= 0.025 \\t= 5

I= (800)(0.025)(5)

Multiply.

I=20(5)\\I=100

After 5 years, Suzette's account has earned $100.00

A ball rolls over the edge of a platform with only a horizontal velocity. The height of the platform is 1.6 m and the horizontal
Sever21 [200]

Answer:

35 m/s

Step-by-step explanation:

Let gravitational acceleration g = 9.8m/s2. We can calculate the amount of time for the ball to fall vertically a distance of 1.6 m

1.6 = 9.8t^2/2

t^2 = 2*1.6/9.8 = 0.327

t = \sqrt{0.327} = 0.571s

This is also the time it takes for the ball to fly horizontally, assume constant horizontal speed, we can calculate the speed it takes to travel across 20m in 0.571s

v = 20 / 0.571 = 35 m/s

Given the following linear function sketch the graph of the function and find the domain and range f(x)=-3x+7
natka813 [3]
<h3>Answer:</h3>

see attached for a graph

domain and range: all real numbers

<h3>Step-by-step explanation:</h3>

The function is written in slope-intercept form, showing that it has a slope of -3 and a y-intercept of +7. The y-intercept (0, 7) is a point on the line, as is a point 1 unit to the right and down 3 units, (1, 4).

The graph will be the line through these two points.

_____

As with any odd-degree polynomial function, both domain and range are all real numbers: (-∞, ∞).
