Answer:

Step-by-step explanation:

r =  3 km

Ф = 90°

Area of a sector = \frac{theta}{360}*\pi *r^{2}

                           =  \frac{90}{360}* 3.14 * 3 * 3\\\\=  \frac{3.14*3*3}{4}\\

                           = 7.065 sq.km

Terry sees this offer refurbished phone 35% off now only ?78 what was the original price
Ronch [10]

Answer:

$223.

Step-by-step explanation:

Let x be the original price of phone.          

We are told that Terry sees this offer refurbished phone 35% off now only $78.

We need to find x such that 35% of x is 78. We can represent this information as:

\frac{35}{100} x=78

0.35 x=78

x=\frac{78}{0.35}    

x=222.8571428571428571\approx 223

Therefore, the original price of phone was $223.

Which graph represents the function f(x)=-|x|-2?
skad [1K]

Answer:

ind the absolute value vertex. In this case, the vertex for y=−|x|−2 is (0,−2).

(0,−2)

The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined.

Interval Notation:

(−∞,∞)

Set-Builder Notation:  {x|x ∈ R}

For each x value, there is one y value. Select few x values from the domain. It would be more useful to select the values so that they are around the x value of the absolute value vertex.

 x     y

−2   −4

−1    −3

 0   −2

 1    −3

 2   −4
