A ball is thrown in the air from a ledge. Its height in feet is represented by f(x) = –16(x2 – 7x – 8), where x is the number of
lbvjy [14]
f(x)=-16( x^{2} -7x-8)

is the functions that determines the height of the ball in Feet, after x seconds being thrown.

so for example to calculate how many feet above the ground in the ball 5 seconds after being thrown, we calculate f(5)

f(5)=-16( 5^{2} -7*5-8)=-16(25-35-8)=-16(-18)=288 feet

to solve our problem we need to find x such that f(x)=0

so we solve :

-16( x^{2} -7x-8)=0

x^{2} -7x-8=0

using the quadratic formula, le a=1, b=-7, c=-8

\sqrt{D} = \sqrt{ b^{2}-4ac}= \sqrt{ (-7)^{2}-4(1)(-8) }= \sqrt{49+32}= \sqrt{81}=9

so 

x_1= \frac{-b+ \sqrt{D} }{2a}= \frac{7+9}{2}= \frac{16}{2}=8

x_1= \frac{-b- \sqrt{D} }{2a}= \frac{7-9}{2}= \frac{-2}{2}=-1, which cannot be the solution to our problem.

The balance of errands average balance checking account at the beginning of last cycle was $400 and the only transaction for the
Tom [10]

Answer:

$300

Step-by-step explanation:

Here we are given:

Balance at the beginning of last cycle(first half) = $400

Balance halfway through the cycle(second half cycle) = $200

To find the amount Aaron's checking account pay interest last cycle, let's find the average balance.

Use the formula for average:

\frac{Bal 1 + Bal 2}{2}

\frac{400 + 200}{2}

\frac{600}{2} = 300

Average = $300

Therefore, the amount Aaron's checking account pay interest last cycle is $300

The sales tax rate in Wilson County is 6.75%.  Suppose total price of an item that you bought in Wilson County including taxes i
schepotkina [342]
Sales Tax rate: 6.75%
Total price of item including tax: $14.93Original price of item: ?
Let x be the original price
x+0.0675x = 14.93  -- we change the percent to decimal

1.0675x = 14.93  -- simplify 
1.0675x/ 1.0675 = 14.93/1.0675  --isolate x
x = 14.93/1.0675  --divide
x = 13.98595  
Then rounded to two decimal points, the answer would be $13.99.
