What is the domain of the function represented by the following graph?
Svetllana [295]

Hello!

The domain of the function are the x-values that make the function true.

Since the graph has open circles and filled in circles, the open circles make the function false (written as <) , and the filled in circles make it true (written as ≤).

From the graph, the x value -3, and 2 are open circles. While the value -0.5 are filled in circles. Also, from the interval (-0.5, 2), there is gap, so it is part of the domain.

Therefore, the domain of the function is: {x | -3 < x ≤ -0.5} ∪ {x | 2 < x < ∞}, which is the third choice.

Identify the missing numbers below:
IRISSAK [1]

Answer:

A = 7.7

b = 26

Step-by-step explanation:

(3.5  \times 10^{16})(2.2  \times  10^{10}) = A  \times  10^b \\ 3.5 \times 2.2 \times 10^{16} \times 10^{10}= A  \times  10^b \\ 7.7 \times  {10}^{16 + 10} = A  \times  10^b \\ 7.7 \times  {10}^{26} = A  \times  10^b \\ equating \: like \: terms \: on \: both \: sides \\  A = 7.7  \\  10^b = {10}^{26}  \\  \implies \: b = 26

Whoever answers my question will get a brainliest.
Maurinko [17]

Answer:

see explanation

Step-by-step explanation:

Calculate the distance d using the distance formula

d = \sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2    }

with (x₁, y₁ ) = ((- 2, - 3 ) and (x₂, y₂ ) = (x, 5x + 9 )

d = \sqrt{(x-(-2))^2+(5x+9-(-3))^2}

   = \sqrt{(x+2)^2+(5x+9+3)^2}

   = \sqrt{(x+2)^2+(5x+12)^2}
