Answer:

15 3/4t^2 + 5 1/4

Explanation:

h(t)=-16t^2+400

We can add 400 then - 64 and show as 8^2

= h(t)=-16t^2+400 - 8^2

But we also need to change 16t^2;

We divide 64 into 16 = 16/64 =0.25

and show 16t^2 changes by 0.25 = 1/4

15 3/4t^2 + 400-64

Can now look like

15 3/4t^2 + 5 1/4

As 5 1/4 = 64 x 5 1/4 = 336

Write the equation for Chelsea's graph in

xeze [42]

Answer:

$y=-4x+16$ .

Step-by-step explanation:

From the given graph it is clear that the y-intercept is 16.

The line passes through (-2,24) and (2,8). So, slope of line is

$Slope=\dfrac{y_2-y_1}{x_2-x_1}$

$Slope=\dfrac{8-24}{2-(-2)}$

$Slope=\dfrac{-16}{4}$

$Slope=-4$

Slope intercept form of a line is

$y=mx+b$

where, m is slope and b is y-intercept.

Substitute m=-4 and b=16 in the above equation.

$y=(-4)x+(16)$

$y=-4x+16$

Therefore, the required equation is $y=-4x+16$ .

Como se resuelve el problema que dice " Iara leyó una novela de 540 páginas en tres semanas. La segunda semana leyó el triple qu

Vladimir79 [104]

Answer:

72, 216 , 252

Step-by-step explanation:

Deje que lo que ella leyó inicialmente sea x páginas.

La segunda semana leyó 3 veces esto = 3 * x = 3x.

La tercera semana leyó 5 veces la primera semana menos 108 = 5x-108.

Así que agreguemos todos juntos para obtener x. 3x + x + 5x-108 = 540.

9x = 540 + 108 9x = 648 x = 648/9 = 72 páginas.

Leyó 72 páginas la primera semana.

Ella leyó 3 * 72 en la segunda semana = 216 páginas En la tercera semana leyó 5 (72) -108 = 360-108 = 252 páginas
