Set y=0 for the x intercepts, so expanding it we get x^2+4x+4+5=0 and x^2+4x+9 =0. Using the quadratic formula, we get that x= (-4+-sqrt(16-36))
right here, we see that the square root of something would be negative, so there are no x intercepts.
for the y intercepts, we set x=0 to get 2^2-5=-1.
for the vertex, we use x^2+4x+9 and -b/2a=the x value of the vertex =-4.
Plugging -4 into it, we get -16+16+9=9 for the y value of the vertex, getting (-4,9). Since -1 from (0, -1) is smaller than 9, the parabola forms a frowny face and goes downwards. Plug some random points in, and you'll have it down!

Answer:
Step-by-step explanation:
Desde el concepto de conservación de la energía mecánica, es decir, la energía asociada con el movimiento coherente de un objeto, la energía cinética del objeto, junto con su momento, están conectadas entre sí. Entonces, si un bloque rueda sobre un plano irregular, tiene pérdida de energía mecánica, esto significa que la energía cinética se compensa con las ganancias o pérdidas de la energía potencial de la interacción del objeto.
Hello,
There are 24 hours in a day. If 25% of your day is spent at school, then you spent (24)(0.25) = 6 hours at school.
If 8% of your day is spent eating, then you spent (24)(0.08) = 1.92 hours eating.
Together, this is 6 + 1.92 = 7.92 hours ≈ 7.9 hours spent at school and eating in one day.
Hope this helps!
Answer:
-1/cd
b = -a/cd
Step-by-step explanation:
a = -bcd
Multiplication and division are inverse operations
Multiply each side by -1/cd
a* -1/cd = -bcd * -1/cd
-a /cd = b
