The vertical height v, in feet, of a snowboarder jumping off of an overhang can be modeled by the function h(t)=15-10t-16t^2, where 15 is the initial height (in feet) of the overhang, -10 is the initial vertical velocity (in feet per second), and t is the time (in seconds). How long does it take the snowboarder to land after jumping off the overhang?"

Answers

Step-by-step explanation:

It is given that, the vertical height v, in feet, of a snowboarder jumping off of an overhang can be modeled by the function as :

$h(t)=15-10t-16t^2$

Where

15 is the initial height of the overhang

-10 is the initial vertical velocity

t is in second

We need to find the time taken by the snowboarder to land after jumping off the overhang. At this condition,

h(t) = 0

So, $15-10t-16t^2=0$

On solving above equation using online calculator, we get the value of t = 0.705 seconds. So, the time taken by the snowboarder to land after jumping off the overhang is 0.705 seconds.

I don't know for sure, but I think there might be an error in the way you copied your function. In all of my dealings with these types of problems, I have learned the formula to be h(t) = 15 + 10t - 16t^2. Notice the plus in front of the "10t". This is due to the fact that if he pushes off of the overhang he would have an upward force of 10 feet per second as soon as his feet left the ground. The only thing pulling him back to Earth is gravity, modeled by the "-16t^2". This is derived from a bit of slightly advanced physics involving the gravitational constant, but let's work under my formula for a second...

Either way, we will wind up using the Quadratic Formula (or possibly factoring if the numbers are easy enough to work with). So let's start.

h(t)= 15 +10t - 16t^2

In order to use the QF or factoring I will need to make h(t)=0. Simply done by:

0= 15 +10t -16t^2

Looking at the numbers, I'd prefer to use the QF so here it is:

$x= \frac{-b + or - \sqrt{b^(2)-4ac } }{2a}$

I know that my answer will need to be positive since you can't have a negative value when dealing with time, so I will eliminate the positive sign from the "+or-" part leaving me with:

$x= \frac{-b -\sqrt{b^(2)-4ac } }{2a}$

And I know that a= -16, b= 10, and c=15. So all that's left to do is substitute and solve.

$x= \frac{-10 -\sqrt{-16^(2)-4*-16*15 } }{2*-16}$

There's a decent amount of math that would be difficult and sloppy for me to do over the computer, but all you need to do is solve the rest of the equation and you would get your answer.

Exact answer: $(5-4 √(15) )/(8)$ or rounded answer: ≈1.31 seconds.

Hope this helps!

Olivia runs 15 miles in 3 hours how many miles will she run in 8 hours if she stays the same rate

Answers

Answer:

Olivia will run 40 miles in 8 hours if she maintains the same rate.

Step-by-step explanation:

If Olivia runs 15 miles in 3 hours at a constant rate, we can find her rate of running:

Rate = Distance / Time

Rate = 15 miles / 3 hours

Rate = 5 miles per hour

Now, we can use this rate to calculate how many miles Olivia will run in 8 hours:

Distance = Rate × Time

Distance = 5 miles/hour × 8 hours

Distance = 40 miles

Olivia will run 40 miles in 8 hours if she maintains the same rate.

Answer:

If Olivia stays running at the same rate, She will run 40 miles in 8 hours.

If this helped you let me know. If not, I will improve and make sure my work is correct. Have a nice day!

-(25) +(-30) -(10) +(-10) -(-50) show solution

Answers

Final answer:

The mathematical expression -(25) +(-30) -(10) +(-10) -(-50) simplifies to -25. This is calculated by simply applying the rules of arithmetic, including the rule that subtracting a negative is equivalent to adding.

Explanation:

The original equation is: -(25) +(-30) -(10) +(-10) -(-50). The calculation follows these steps:

Resolve each section individually, starting with -(25) which equals -25.
Next, +(-30) equals -30.
Then, -(10) equals -10.
Next, +(-10) equals -10.
Finally -(-50) equals +50 since subtracting a negative is equivalent to adding a positive.

Now, if we add all these numbers together, it equals:

-25 - 30 -10 -10 + 50 = -25.

cornerstone baker sold 78 pies on monday 96 pies tuesday 104 pies wednesday 40 pies thursday 77 pies friday on average how many pies did they sell per day

Answers

To find the average per day use this equation;

total number of pies ÷ total number of days = average of pies per day

78 + 96 + 104 + 40 + 77 = 395

Monday + Tuesday + Wednesday + Thursday + Friday = 5 days...

395 ÷ 5 = 79

so the average of pies sold per day is : 79 pies per day.
