Answer:

105 km

Step-by-step explanation:

so, 1 cm on the map is 7 km in real life.

15 cm is 15 times 1 cm

so, the real life distance is 15×7 = 105 km

What equation could generate the curve in the graph below

Marianna [84]

Answer:

Step-by-step explanation:

We know the y intercept is positive so that eliminates choice D.

y = 3x^2 -2x+1

This does not intercept the x axis

y = 3x^2 -6x+3

= 3(x^2 -2x+1)

3(x-1)^2

This intercepts the x axis at 1

This is not the equation for the graph

y = 3x^2 -7x+1

Let x = 1

y = 3-7+1

= -3

This will cross the x axis, so this cannot be the graph

Answer:

$\displaystyle \frac{\pi}{6}$

Explanation:

According to the unit circle, $\displaystyle \frac{\pi}{3}$ and $\displaystyle \frac{\pi}{6}$ are the radian measures you are looking for because all <em>y-coordinates</em> are associated with the <em>sine</em> function, so when evaluating, you will arrive at this:
