Answer:

8 miles

Step-by-step explanation:

Britney went from -4 to 6, or 10 miles, and then from 10 to -14, or 24 miles. Add these together and Britney traveled 34 miles

Alice went straight from the library to school, so we need to find the hypotenuse of the triangle. Use the Pythagorean theorem (a^2 + b^2 = c^2) and substitute 10 for a and 24 for b to get 100 + 576 = c^2 or 676 = c^2

Take the square root of 676 to get 26 for Alice's distance.

34-26=8

Consider the line y=7x-3 fine the equation that pass through -5,6 of a perpendicular​
Pavel [41]

Answer:

y=-\frac{1}{7}x+\frac{37}{7}

Step-by-step explanation:

Your equation is in slope-intercept form, y = mx + b, where m is the slope and b is the y-intercept.  Your line has a slope of 7.  In order to find the line perpendicular to this line, we have to take the opposite reciprocal of the slope.  The perpendicular slope to m = 7 is m = -1/7.  Now we go through x = -5 and y = 6 to find the new equation.

6 = -1/7(-5) + b gives us

6 = 5/7 + b and

b = 37/7

Therefore, the equation of the line perpendicular to your original line is

y = -\frac{1}{7}x + \frac{37}{7}

Can someone explain in the clearest way possible how to solve this problem and also does it involve using sin cos tan formulas?
baherus [9]

Answer:

  480 ft

Step-by-step explanation:

The geometry involves two similar triangles. The ruler at arms length forms a triangle that has the opposite side 3 inches high and 24 inches (2 ft) away. That is, the distance from the eye to the ruler is 8 times the height of the ruler.

The triangle involving the lighthouse is similar. That is, the angles in it are the same, so the sides are proportional to those in the smaller (ruler) triangle. The distance to the lighthouse will be 8 times the height of the lighthouse, just as the distance to the ruler is 8 times the height of the ruler.

  8 × 60 ft = 480 ft

The lighthouse is 480 feet away.
