Answer:

yes

Step-by-step explanation:

A function is any graph that the x values do not repeat.

You can check this by using this vertical line test

Run your finger or a pencil down a specific vertical (top to bottom) line on the graph, if you can see that it intersects into the graph more than once, then it's not a function.

Write an equation in standard form for the line that has undefined slope and passes through (-6, 4)

Nikitich [7]

Answer:

y = ix + 6i + 4

Step-by-step explanation:

Since the line has undefined slope or indefinite slope we connote that the slope is (i)

Slope(m) of straight line = change in y ÷ change in x

Taking another point (x,y) on the line:

i = $\frac{y - 4}{x - -6}$

i = $\frac{y - 4}{x + 6}$

Cross multiplying gives;

y - 4 = ix + 6i

y = ix + 6i + 4

Which proportion can be used to find the arc length, s, in units?

Alinara [238K]

Answer:

Option B

Step-by-step explanation:

Formula to be used to calculate the length of an arc,

Length of arc = $\frac{\theta}{360}(2\pi r)$

Here, θ = Angle subtended at the center by the arc

r = radius of the circle

By substituting values in the formula,

s = $\frac{150}{360}(2\pi )(42)$

$\frac{s}{2\times 42\pi }=\frac{150}{360}(\frac{2\times 24\pi }{2\times 24\pi } )$

$\frac{s}{84 \pi }=\frac{150}{360}$

Therefore, Option B will be the answer.
