Quadratic Function help?
Harlamova29_29 [7]
A) The T-shirt will be at its maximum height when the velocity is at zero, because its velocity will be at zero when it reaches the top of its arc.
You have the position function, y= -16t^2 + 72t + 5, so the velocity function is its derivative, v= -32t + 72.
Set that equal to zero, 0= -32t + 72, and solve for t.
0= -32t + 72
32t = 72
t = <u>9/4</u> or <u>2.25 seconds</u>.

b) Plug what you found in part a) back into your position equation.
-16(2.25)^2 + 72(2.25) + 5 = -81 + 162 + 5 = <u>86 feet
</u>
c) The t-shirt's lowest point is 5 feet above the ground (that's the '+ 5' in the position equation) and its highest point is 86 feet, which you found in part b). So the range is <u>[5,86]</u>

216 raised to the power 1/3 can also be written as cube root of 216. 

Changing the given expression to radical form, we can write:

(216)^{ \frac{1}{3} }  \\  \\ &#10;= \sqrt[3]{216}

216 is the cube of 6 i.e. multiply 6 three times (6 x 6 x 6), you will get 216.
So we can write the above expression as:

\sqrt[3]{(6)^{3} }

The cube root and cube cancel out each other, leaving the answer equal to 6.

So, the correct answer is option B

Se desea construir una letra "ene" mayúscula de tal manera que sus segmentos paralelos midan 25 cm y el
Anna71 [15]

Answer:

La distancia en línea recta que separa los segmentos paralelos es 60cm.

Step-by-step explanation:

Esta pregunta se puede resolver usando el <em>teorema de Pitágoras</em>:

\\ c^2 = a^2 + b^2 [1]

Es decir, en <em>triángulos rectágulos</em>, el cuadrado de la hipotenusa es igual a la suma de los cuadrados de los catetos de dicho triángulo. Un triángulo es rectángulo cuando el ángulo que forman sus dos catetos es recto o de 90 grados sexagesimales.

Es importante notar que la letra N tiene dos lados paralelos y el lado oblicuo (o inclinado) une ambos lados paralelos. Pues bien, la letra N puede formar dos triángulos iguales. Escojamos uno de ellos para obtener la respuesta, es decir, <em>la distancia en línea recta que separa los segmentos paralelos</em> (segmentos verticales de la N)

El <em>lado oblicuo</em> (inclinado) es la <em>hipotenusa de ese triángulo </em>(es decir, c)<em>. </em>De los catetos, uno está representado por uno de los <em>segmentos paralelos</em> (verticales) de la N (digamos que es b), y, el otro cateto, es la <em>distancia horizontal</em> que une ambos segmentos verticales (digamos que es a).

Si unimos el segmento inferior del <em>cateto b</em> con el extremo inferior de la <em>hipotenusa</em>, se forma el <em>cateto </em><em>a</em>. Este <em>cateto a</em> forma un ángulo recto con el cateto b y, por lo tanto, forma un triángulo recto. Los lados de un triángulo recto pueden resolverse usando el <em>teorema de Pitágoras</em>, descrito en [1].

Usando [1] y despejando a, tenemos:

\\ c^2 = a^2 + b^2

Restamos \\ b^2 de ambos lados de la igualdad:

\\ c^2 - b^2 = a^2 + b^2 - b^2

\\ c^2 - b^2 = a^2 + 0

\\ c^2 - b^2 = a^2

Luego

\\ a^2 = c^2 - b^2

Extrayendo la <em>raíz cuadrada</em> en cada lado de la igualdad:

\\ \sqrt{a^2} = \sqrt{c^2 - b^2}

Entonces

\\ a = \sqrt{c^2 - b^2}

Asimismo, tenemos que \\ c = 65cm y \\ b = 25cm

Entonces,

\\ a = \sqrt{65^2 - 25^2}

\\ a = \sqrt{4225 - 625}

\\ a = \sqrt{3600}

\\ a = 60cm

De esta manera, el valor de a, o <em>la distancia en línea recta que separa los segmentos paralelos</em>, es 60cm.

Podemos comprobar el resultado anterior haciendo uso del mismo <em>teorema de Pitágoras</em>:

\\ 65^2 = 60^2 + 25^2

\\ 4225 = 3600 + 625

\\ 4225 = 4225

En la figura anexa se aprecia gráficamente lo anteriormente explicado.
