A kite is flying 99 ft off the ground, and it's strong is pulled taut. The angle of elevation of the kite is 41°. Find the lengt

Luba_88 [7]

Answer:

the length of the string=150.9

Step-by-step explanation:

height of a kite=99 ft

angle of elevation =41

use formula

sin 41= opposite/hypotenuse( opp is the elevation, hypotenuse is the string)

sin 41 = 99/hyp.

hyp.=99/sin41

hyp= (99)/(0.65605902)

hyp.=150.9( rounded to the nearest tenth)

La edad de Alejandro equivale a las dos quintas partes de la edad de Andrea. Si la suma de

Mariana [72]

Las edades de Andrea y Alejandro son 40 y 16 años, respectivamente.

En esta pregunta debemos traducir el enunciado en ecuaciones algebraicas y resolver el sistema resultante. Tras una lectura cuidadosa tenemos el siguiente sistema de ecuaciones:

$y = \frac{2}{5}\cdot x$ (1)

$x + y = 56$ (2)

Donde:

$x$ - Edad de Andrea, en años.
$y$ - Edad de Alejandro, en años.

A continuación, procedemos a resolver el sistema:

(1) en (2):

$x + \frac{2}{5}\cdot x = 56$

$\frac{7}{5}\cdot x = 56$

$7\cdot x = 280$

$x = 40$

Por (1):

$y = \frac{2}{5}\cdot 40$

$y = 16$

Las edades de Andrea y Alejandro son 40 y 16 años, respectivamente.

Slope is -2 and (5, 3) is on the line. What is the equation in slope intercept form?

Kruka [31]

$\bf \begin{array}{lllll}
&x_1&y_1\\
% (a,b)
&({{ 5}}\quad ,&{{ 3}})
\end{array}
\\\\\\
% slope = m
slope = {{ m}}= \cfrac{rise}{run} \implies -2
\\\\\\
% point-slope intercept
\stackrel{\textit{point-slope form}}{y-{{ y_1}}={{ m}}(x-{{ x_1}})}\implies y-3=-2(x-5)
\\\\\\
y-3=-2x+10\implies y=-2x+13$
