Hey there! :)

Answer:

d ≈ 3.49 units

Step-by-step explanation:

Use the distance formula for polar coordinates to determine the distance:

$d = \sqrt{r_{1} ^{2}+r_{2} ^{2}-2r_{1}r_{2}cos(0_{1}- 0_{2} ) }$ (The '0' is supposed to be theta)

Plug in the values given in the question. Convert radians to degrees to simplify the process.

217π/180 = 217°

-23π/36 = -115°.

Therefore:

$d = \sqrt{7 ^{2}+5 ^{2}-2(7)(5)cos(217-(-115) ) }$

Begin simplifying:

$d = \sqrt{74-70cos(332) }$

$d = \sqrt{74-61.81 }$

Solve:

$d = \sqrt{12.19 }$

d ≈ 3.49 units

Which graph has a domain of -∞ < x < ∞ and a range of -∞ < y

Alenkasestr [34]

The graph of the option in the question has a domain of -∞ < x < 3.5.

Please find attached the drawing of a graph that has a domain of -∞ < x < ∞

<h3>Which method can be used to find the graph that has a domain of -∞ < x < ∞?</h3>

The domain of a graph are the possible x-values that can be obtained from the graph.

A graph that has a domain given by the inequality, -∞ < x < ∞ does not have a vertical asymptote.

An asymptote is a straight line to which a graph approaches, as either the x or y-value approaches infinity.

The given graph has a vertical asymptote at y ≈ 3.5

The domain of the given graph is therefore, -∞ < x < 3.5

Similarly, the graph has a horizontal asymptote at x ≈ 3

The range of the given graph is therefore, -∞ < y < 3.

A graph that has a domain of -∞ < x < ∞, extends to infinity to the left and the right of the graph.

A function that has a graph with a domain of -∞ < x < ∞ is one of direct proportionality.

An example is, y = x

A graph that has a domain of -∞ < x < ∞ is attached.

aleksley [76]

Answer:

4:7

Step-by-step explanation:

4:7

they make 7 cakes in total (3:4 = 7).

there are 4 vanilla cakes.

therefore, the ratio of vanilla cakes to the total number of cakes is 4:7.

Solve for x and y. -4x + 8y = -4 4x = 3y + 14

algol13

Hello!! Lets do this step by step! :)
−4x+8y=−4;4x=3y+14 
To first get x:
−4x+8y+−8y=−4+−8y we are ganna add -8y to both sides
−4x=−8y−4−4x−4=−8y−4−4 we are ganna divide both sides by -4
x=2y+1
next just substitute 2y+1 for x in 4x=3y+14:4x=3y+144(2y+1)=3y+148y+4=3y+148y+4+−3y=3y+14+−3y
we are ganna add -3y to both sides 5y+4=145y+4+−4=14+−4
we are ganna add -4 to both sides 5y=105y5=105
now we are ganna divide both sides by 5 y=2substitute 2 for y in x=2y+1:x=2y+1x=(2)(2)+1x=5

And we get our answer!
x=5
y=2

Hope that helps! If you have any other questions or need further explanation just let me know! :)
