Considering that each input is related to only one output, the correct option regarding whether the relation is a function is:

A. yes.

<h3>When does a relation represent a function?</h3>

A relation represents a function when each value of the input is mapped to only one value of the output.

For this problem, we have that:

The input is a number.

The output is an activity.

There are no repeated inputs, hence the relation is a function and option A is correct.

<h2>A)t=6.7</h2>

Step-by-step explanation:

<h3>to understand this</h3><h3>you need to know about:</h3>

quadratic equation
quadratic equation word problems
solving quadratic

<h3>given:</h3>

h(t) = -4t² + 12t + 100

<h3>to solve:</h3>

t

<h3>tips and formulas:</h3>

<u>the</u><u> </u><u>Ball</u><u> </u><u>will</u><u> </u><u>hit </u><u>the</u><u> ground</u><u> </u><u>when</u><u> </u><u>the</u><u> height</u><u> is</u><u> </u><u>0</u>
<u>solving</u><u> </u><u>quadratics </u><u>using</u><u> </u><u>quadratic</u><u> formula</u>
<u>PEMDAS</u>

<h3>let's solve: </h3>

$step - 1 : \: define$

$- 4 {t}^{2} + 12t + 100 = 0$

$step - 2 : \\ divide \: both \: sides \: by \: - 4$

${t}^{2} - 3t - 25 = 0$

$step - 3 : \\ solve \: the \: quadratic$

$formula : \\ x = \frac{ - b± \sqrt{ {b}^{2} - 4ac } }{2a}$

$define \: a ,b \: and \: c \\ which \: are \: 1, - 3 \: and \: - 25 \: respectively$

$t = \frac{ - ( - 3)± \sqrt{ {( - 3)}^{2} - 4.1. - 25 } }{2.1}$

$t = \frac{ 3± \sqrt{ 9 + 100} }{2}$

$t = \frac{3 + \sqrt{ 109 } }{2}$

$t = \frac{3 - \sqrt{ 109 } }{2}$

$t = 6.7 \\ t = - 3.7$

$as \: we \: know \: time \: cannot \: be \: negative$

$\huge \therefore \: t = 6.7$

El agua de una psicina alcanza 250 cm de altura. Si la estatura de pablo es 1520 mm dentro de la piscina sin que el agua lo cubr

Andrews [41]

Respuesta:

Pablo se cubrirá de agua si se para en la piscina

Explicación paso a paso:

El nivel del agua en la piscina = 250cm.

Altura de Pablo = 1520 mm

Para saber si pablo podría pararse en la piscina sin estar cubierto de agua, necesitamos determinar la altura de Pablo en centímetros.

Convertir la altura de Pablo de milímetro a centímetro;

1 mm hasta 0,1 cm

1520 mm = (1520 * 0,1) = 152 cm

Por lo tanto, pablo mide 152 cm.

Esto significa que la altura del agua en la piscina es mayor que la altura de Pablo y esto lo cubrirá el agua si se para en la piscina.

2x+3y=9<br> 2x+y=7<br> simultaneous equation

Marat540 [252]

Answer:

x=3 and y=1

Step-by-step explanation:

subtract equation 2 from 1

then (2x+3y) -(2x+y) =9-7

2x-2x+3y-y =2

2y=2 therefore y=1

substitute y value in 2x+y=7

2x+1=7

2x=7-1

2x=6

x=3
