While setting up a fireworks display, you have a tool at the top of the

building and need to drop it to a coworker below. Given the equation:

h(t) = -16t^2 + h0

h = 84 feet

it will take the tool to fall to the ground 2.29 time unit

-84 = -16t^2 – 0

<span>t = 2.29 time unit</span>

After putting $5,500 as a down payment on a car, you pay $400 per month for 60 months to pay off your car. What was the total yo
Y_Kistochka [10]

Answer:

$29500

Step-by-step explanation:

Given data

The number of months is 60

the downpayment is $5,500

the monthly payment is $400

Let the function for the total payment be given as

y=mx+c

y= 400(60)+5500

y=24000+5500

y= 29500

Hence the total paid for the car is $29500

6. Consider the polynomial p(x) = x^2 + kr^2 +x+6. Find a value of k so that x+1 is a factor of P. Find all the zeros of P.​
Nikitich [7]

If <em>x</em> + 1 is a factor of <em>p(x)</em> = <em>x</em>³ + <em>k</em> <em>x</em>² + <em>x</em> + 6, then by the remainder theorem, we have

<em>p</em> (-1) = (-1)³ + <em>k</em> (-1)² + (-1) + 6 = 0   →   <em>k</em> = -4

So we have

<em>p(x)</em> = <em>x</em>³ - 4<em>x</em>² + <em>x</em> + 6

Dividing <em>p(x)</em> by <em>x</em> + 1 (using whatever method you prefer) gives

<em>p(x)</em> / (<em>x</em> + 1) = <em>x</em>² - 5<em>x</em> + 6

Synthetic division, for instance, might go like this:

-1   |   1    -4     1     6

...   |         -1    5    -6

----------------------------

...   |   1    -5    6     0

Next, we have

<em>x</em>² - 5<em>x</em> + 6 = (<em>x</em> - 3) (<em>x</em> - 2)

so that, in addition to <em>x</em> = -1, the other two zeros of <em>p(x)</em> are <em>x</em> = 3 and <em>x</em> = 2
