April shoots an arrow upward at a speed of 80 feet per second from a platform 25 feet high. The pathway of the

zaharov [31]

Answer:

The maximum height of the arrow is 125 feet.

Step-by-step explanation:

The pathway of the arrow can be represented by the equation,

$h = -16t^2 +80t + 25$ .....(1)

Where h is height in in feet and t is time in seconds.

It is required to find the maximum height of the arrow. For maximum height, $\dfrac{dh}{dt}=0$ .

So,

$\dfrac{d(-16t^2 +80t + 25)}{dt}=0\\\\-32t+80=0\\\\t=\dfrac{80}{32}\\\\t=2.5\ s$

Put t = 2.5 s in equation (1). So,

$h = -16(2.5)^2 +80(2.5) + 25\\\\h=125\ \text{feet}$

So, the maximum height of the arrow is 125 feet.

Please help me to find the answer Y=2X 3X+4Y=22 Y=2X 3X+4Y=22

RSB [31]

<h3>System of equations.</h3>

$\left\{\begin{array}{ccc}y=2x&(1)\\3x+4y=22&(2)\end{array}\right$

Put (1) to (2):

$3x+4(2x)=22\\3x+8x=22\\11x=22\qquad|\text{divide both sides by 11}\\\boxed{x=2}$

Substitute the value of x to (1):

$y=2\cdot2\\\boxed{y=4}$

Solution:

$\huge\boxed{\left\{\begin{array}{ccc}x=2\\y=4\end{array}\right}$
