Una avioneta vuela entre las ciudades A y B. Su altura viene dada por la siguiente funcion: h(t)=840t-30t elevado al 2,, siendo h(T) la altura de la avioneta( en metros) a los t (minutos) de haber despegado. a) cuanto dura la avioneta para ir desde la ciudad A hasta la ciudad B?
b) a que altura la avioneta inicia el descenso?
c) grafique la funcion e indique su dominio e imagen

3.4 pizzas

step-by-step explanation:

given is a scatter plot showing number of pizzas sold during weeks for different issues of coupon

y represents number of pizzas sold and x number of coupons issued

y is marked verticaly and x horizontally

the trend line is given as

y =3.4x+43

this says that even when no coupon is issued pizzas sold will be 43

and rate of change of pizza sold for 1 unit of coupon = slope = 3.4

i.e. when x increases by 1 unit y increases by 3.4 units

hence for each additional coupon issued 3.4 pizzas more will be sold

rounding to the nearest thousandth would be 452,000

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
