Answer:

B,C

Step-by-step explanation:

So all you have to do is use the pythagorean theorem to solve this (a²+b²=c²).

Plug in the two shorter sides for a and b and the long side for c. If both sides equal the same thing then it will make a right triangle.

A) 5²+6²=9²

25+36=81

61≠81

B) 0.25+1.44=1.69

C)49+576=625

D) 100+256≠361

E)1+4≠9

Una poblacion es atacada por una epidemia de gripe sea N(t)= numero de personas enfermas al tiempo t. En dias la epidemia inicio

Lisa [10]

Answer:

<em>Habrán 10175 enfermos a los 15 dias.</em>

Step-by-step explanation:

La tasa de cambio de la población enferma por la epidemia de gripe es:

$N'(t)=120t-3t^2$

Donde t es el tiempo en dias, y se sabe que la epidemia inició en N(0)=50.

Para encontrar la función original que describe el comportamiento de la epidemia, debemos integrar la función:

$N(t)=\int N'(t)dt$

$N(t)=\int (120t-3t^2)dt$

Integrando:

$\displaystyle N(t)=120\frac{t^2}{2}-3\frac{t^3}{3}+C$

Simplificando:

$\displaystyle N(t)=60t^2-t^3+C$

Para determinar el valor de C, usamos la condición inicial N(0)=50:

$\displaystyle 50=60(0)^2-(0)^3+C$

Se tiene que C=50, y la función queda determinada como:

$\displaystyle N(t)=60t^2-t^3+50$

b) El número de enfermos a los t=15 dias se determina substituyendo el valor en la función original:

$\displaystyle N(15)=60(15)^2-(15)^3+50$

Calculando:

$N(15)=13500-3375+50=10175$

Habrán 10175 enfermos a los 15 dias.

A horizontal curve is being designed around a pond with a tangent length of 1200 ft and a central angle of 29.86 degrees. If the

lara31 [8.8K]

Answer:

The correct answer is "1287.02 ft"

Step-by-step explanation:

Given that:

T = 1200 ft

PI = 145+00

$\Theta$ = 29.86°

or,

= 0.5211 rad

As we know,

The radius of curve is:

⇒ $T = R \ tan\frac{\Theta}{2}$

$1200=R \ tan(\frac{0.5211}{2} )$

$1200=R \ tan(0.267)$

$R = 4494.38 \ ft$

The length of curve will be:

⇒ $L=R \Theta$

$=449.38\times 0.5211$

$=2342.01 \ ft$

hence,

Station PT will be:

= $PI-T+L$

= $145-1200+2341.01$

= $1287.02 \ ft$

Help plz can’t figure this out

xxMikexx [17]

Answer:

The publisher must sell 4,632 books in order to break even(total sold equals production costs).

Step-by-step explanation:

So the bookstores are really making $24-10.25 in profit off of each book. This equals $13.75 profit for every book sold.

So you set up an equation:

13.75x=$63,690

x=63690/13.75

x=4632
