En la figura a continuación tenemos un circulo cuyo centro es R. (a) Identificar un diámetro: RU W T (b) Identificar un radio: (c) Identificar una cuerda: (d) si la longitud de ST es 8 unidades, S ¿cuál es la longitud de RU? U unidades Х 5 ?​

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

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,

the answer is 5/14.

hope this .
