find the measures of an angle between 0°and 360° coterminal with an angle of -271° in standard position
alisha [4.7K]

We are given angle in standard position as

\theta=-271

we know that one complete rotation is 360

so, to find angle between 0 and 360

so, we will add 360 to get co-terminal angle

so, co-terminal angle is

=\theta +360

now, we can plug value

co-terminal angle is

=-271 +360

Si colocan en 16 pisos, 16 ladrillos. ¿Cuántos ladrillos pusieron en total?. (expresarlo en forma de potencia)
inn [45]

Answer:

Númer total de ladrillos= 256

Step-by-step explanation:

<u>Dada la siguiente información:</u>

Total de pisos= 16

Total de ladrillos por piso= 16

<u>Para calcular cantidad de ladrillos en total, tenemos que usar la siguiente formula:</u>

Número total de ladrillos= total de ladrillos^2

Número total de ladrillos= 16^2

Númer total de ladrillos= 256

En este caso lo hace al cuadrado por que la cantidad de pisos y ladrillos por piso es la misma. Sino, es mejor expresarlo como una multiplicación.

What is the graph of the function x^2-9x+20 over x-4
Greeley [361]

Answer:

  a straight line: y = x -5, with a hole at (4, -1)

Step-by-step explanation:

The rational function can be simplified to ...

  f(x)=\dfrac{x^2-9x+20}{x-4}=\dfrac{(x-5)(x-4)}{(x-4)}\\\\f(x)=x-5\qquad\text{$x\ne 4$}

The graph of this is a straight line, with a hole at x=4, where the function is not defined.
