Can someone please help me with these two Pre-Calc questions? 1. Write the equations of the circles that satisfy the following conditions (note: there are two circles)
• Radius = 5
• Center is on the line 2x + y - 4 = 0
The circles are tangent to the line 3x + 4y - 6 = 0

2. A tractor trailer is carrying a cargo that is covered with a tarp and is rectangular shaped when viewed from the rear. The entire width of the truck and its cargo is 14 feet. The driver needs to drive through a semi circular Archway (underpass of a bridge) whose maximum height is 25 feet. If the overall height of the truck and its cargo is 24.5 feet, Will it fit under the bridge safely? Assume the driver realizes that she must drive down the center of the road in order to do this. Please explain in detail your choice.

i can you answer this question sweetie!

step-by-step explanation:

la parábola es el lugar

geométrico en el cual los puntos tienen una distancia idéntica, equidistantes,

de un punto denominado foco, f, y una recta denominada directriz

el radio vector de una

parábola es el segmento que existe entre un punto cualquiera y el foco.

por la ecuación se observa

que la parábola abre hacia la derecha, por lo cual podemos usar las siguientes fórmulas

la ecuación ordinaria de la

parábola es y^2 = 4px, donde p es la longitud desde el vértice de la parábola al

foco.

la fórmula de la directriz

es x + p = 0

resolviendo:

y^2-9x = 0

y^2 = 9x

4p = 9, entonces p = 9/4

entonces el foco tendrá la

coordenada f(9/4,0)

la directriz vendrá

expresada por

x + p = 0

x = -p

x = -9/4

el problema indica que la

ordenada es igual a 6, entonces

(6)^2=9x

x = 36/9

x = 4

entonces el punto al cual

hay que obtener la distancia será p(4,6)

calculando se tendrá: pf = 

pf = 6,25 u
