Answer: ok so
quadrilateral-4 sides
1. not a paralellogram
A. trapezoid (1 pair of paralell sides)
2. paralellogram (2 pairs of paralell sides)
A. rectangle-4 right angles
B. rhombus-4 equal sides
C. squaer - 4 equal sides and 4 right angles (both a rhombus and rectangle)
D. kite. 2 pairs of paralell sides that are next to each other (looks like a kite)

5. 4 equal sides, no right angle: rhombus
6. 4 right angles, all sides equal legnth:squaer
7. 1 pair of paralel sides:trapezoid
8. 4 right angles:rectangle
9. if a rectangle has 4 equal sides it is technically a squaer and a rhombus
all squares are recangles and rhombuses, but not all rhombuses and rectangles are squaers

5. rhombus
6. square
7. trapezoid
8. rectangle
9. it is has 4 equal sides, then yes

The sum of the interior angles of any regular polygon is (n - 2) X 180
30 = n
[(30) - 2] × 180
28 X 180
5040

The interior angle of a regular polygon = the sum of interior angles ÷ number of sides
5040 ÷ 30 = 168

Therefore the measure of each interior angle in a regular 30-sided polygon is 168°

Find the measure of Angle 2.

Find n.
2/9=14/n
n=_____

Answers

2/9 = 14/n
14÷2/9 = 14/n÷14
63 = n

So, n=63

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!
