Does anyone know the answer

Answer:

The arrow will hit the ground approximately 10.5 seconds after launch.

Step-by-step explanation:

The arrow experiments a free fall motion, which is a particular form of uniform accelerated motion due to gravity and in which air friction and effects from Earth's rotation can be neglected. Then, the height as a function of time ([tex]h(t)[/tex]), measured in feet, is obtained by the following kinematic formula:

[tex]h(t) = h_{o}+v_{o}\cdot t + \frac{1}{2}\cdot g \cdot t^{2}[/tex] (1)

Where:

[tex]h_{o}[/tex] - Initial height of the arrow, measured in feet.

[tex]v_{o}[/tex] - Initial velocity of the arrow, measured in feet per second.

[tex]t[/tex] - Time, measured in seconds.

[tex]g[/tex] - Gravitational acceleration, measured in feet per square second.

If we know that [tex]h(t) = 0\,ft[/tex], [tex]h_{o} = 35\,ft[/tex], [tex]v_{o} = 166\,\frac{ft}{s}[/tex] and [tex]g = -32.174\,\frac{m}{s^{2}}[/tex], then the following polynomial is obtained:

[tex]35+166\cdot t -16.087\cdot t^{2}=0[/tex] (2)

Lastly, we find the roots of the given expression by the Quadratic Formula:

[tex]t_{1}\approx 10.526\,s[/tex] and [tex]t_{2} \approx -0.207\,s[/tex]

Time is a positive variable and then we conclude that the only solution that is physically reasonable is approximately 10.526 seconds.

The arrow will hit the ground approximately 10.5 seconds after launch.

Step-by-step explanation:

rate of change =y/x

= _5

rate of change = 1

Rate of Change: The speed at which a variable changes over a specific period of time. It is often used when speaking about momentum, and it can generally be expressed as a ratio between a change in one variable relative to a corresponding change in another. Graphically, this ratio is represented by the slope of a line.

Given equation:

y = x - 5

rate of change = m = ?

Comparing the equation with slope intercept form of line

y = mx + c

slope m = 1

c = -5

Hence the rate of change (slope m)  = 1

Answer: 26

Step-by-step explanation: Since you are given the measures of two legs which are 24 (XY) and 10 (XS), you just need to use the formula a^2+b^2=c^2 to find the hypotenuse which is RY.

10^2 + 24^2 = c^2

100 + 576 = c^2

676 = c^2

26 = c

RY = 26

Step-by-step explanation:

Answer: 81 consecutive free throws

Step-by-step explanation: Since 78 of 90 attempted free throws equals to 88.89%, then try adding 3 to 78, (78 + 3) which equals to 81. If you convert 81/90 to a percentage, you get 90%. So your final result or answer is 81 consecutive free throws.

Tip: To convert a fraction to a percentage, divide the denominator by the numerator and you should get a decimal quotient. Lastly, just add a percentage sign.

Given parameters:

Rate of the biker = 8mph

Unknown:

Time taken to travel 32miles  = ?

Solution:

We have been given the speed of the bike which is 8mp.

 Speed is the distance covered per unit of time. It is mathematically expressed as;

      Speed  = [tex]\frac{distance}{time}[/tex]

So,

  Time  = [tex]\frac{distance }{speed }[/tex]  

Now, insert the parameters and solve;

   time  = [tex]\frac{32}{8}[/tex]   = 4hrs

Answer:

-13

Step-by-step explanation:

-13

The evaluated value of the given function is -

│-9│+ │11│ - │-15│ + │-6│= 11.

A function is a relation between a dependent and independent variable. We can write the examples of functions as -

y = f(x) = ax + b

y = f(x, y, z) = ax + by + cz

We can define the modulus function as -

|x| = - x     {x < 0}

|x| = x       {x > 0}

Given is to evaluate the expression -

│-9│+ │11│ - │-15│ + │-6│

We can evaluate the function as -

│-9│+ │11│ - │-15│ + │-6│

9 + 11 - 15 + 6

20 - 9

11

So, we can write -

│-9│+ │11│ - │-15│ + │-6│= 11

Therefore, the evaluated value of the given function is -

│-9│+ │11│ - │-15│ + │-6│= 11.
