Complete Question

A juggler tosses a bowling pin in the air with an initial velocity of 18 ft per second. It leaves his hand when it is five feet from the ground and he catches it when it is four feet from the ground,How long is the ball in the air?

Answer:

t\approx 0.1s

Step-by-step explanation:

From the question we are told that

Initial velocity  V_0= 18 ft/s

Initial Height    h_1=5feet

Final Height     h_2=4feet

Generally the Newtons equation for motion is mathematically given by

   V^2 = U^2 + 2as

Where

    s=h_2-h_1\\s=4-5\\s=-1ft

And

   a=g=>9.81\\a=32.2ft/s^2

Therefore

   V^2 = (18)^2 + 2(-32.2)(-1)

   V^2 = 388.4

   V =19.70786645\\V=19.71ft/s

Generally the equation for Time is mathematically Given as

   t=\frac{V-U}{a}

   t=\frac{19.71-18}{32.2}

   t=0.05310559006

   t\approx 0.1s

Therefore the time spent on air by the ball is

    t=0.05310559006s

bija089 [108]
A parallelogram

Because...
-opposite angles are congruent
-four sides
-angles must equal 360
       100 + 100 +80 + y = 360

       280 + y = 360

       y = 80
-the angle we don't know is 80 degrees

Determine if the equation y = 2(0.45)x represents exponential growth or decay
djverab [1.8K]
We have that
y = 2(0.45)^x

in this problem 
2-----------> is the Coefficient
0.45-------> is the Base
<span>x-----------> is the Exponent

we know that
</span><span>If the base  is less than 1 (but always greater than 0), the function will be exponential decay
</span>It is decay because as x values increase, y values decrease.
<span>0.45 < 1  and 0.45 > 0
therefore

the equation
</span>y = 2(0.45)^x
represents <span>exponential decay
</span>
the answer is
exponential decay<span>

</span>

If ƒ(x) = -5n + 1 and g(x) = -6n + 2, find (ƒ + g)(-2).
Stels [109]

(f+g) (n) = (–5n +1 ) + (- 6n +2) = –11n +3

(f+g) (n) = –11n +3

(f+g) (–2) = – 11 (–2) +3 = 22 +3 = 25

I hope I helped you^_^
