Answer:
94°
Step-by-step explanation:
it is a similar triangle and corresponding angles of similar triangles are equal. and interior angles of triangles always equal to 180°
Let's pick two points on the line, the
y-intercept, and the
x-intercept. These are the points at which x=0, and y=0.
When x=0:

So one point is
(0,6)When y=0:

So another point is
(10,0)
So mark the points
(0,6) and
(10,0) on a pair of axes, and draw a straight line between them, and past them to infinity. This is a graphing of the line y=-3/5 x + 6
Answer:
377
Step-by-step explanation:
5 / 32 = 59 / x
x = 377.6
Answer:
Step-by-step explanation:
Let the speed of the roller coaster at the bottom is v.
radius, r = 47 m
Let the mass is m and the force at the bottom is 2.5 times the weight.
F = 2.5 mg
So, the force is



v² = 1.5 gr
v² = 1.5 x 9.8 x 47
v = 26.3 m/s
9514 1404 393
Answer:
(c) Both equations have the same potential solutions, but equation A might have extraneous solutions.
Step-by-step explanation:
The general approach to solving an equation like either of these is to raise both sides of the equation to a power that will remove the radical. In both cases, the result is a quadratic with roots of x=-4 and x=2.
Of these two potential solutions, x = -4 is an extraneous solution for equation A. Both values of x are solutions for equation B. An appropriate description is ...
Both equations have the same potential solutions, but equation A might have extraneous solutions.

<em>Additional comment</em>
The attached graph shows the equations cast into the form f(x) = 0, so x-intercepts are the solutions to the equation. The radical versions of the equations have only x-intercepts that are actual solutions. The version with the radicals removed is a parabola with two solutions (orange). Only one of those matches the solution to equation A (red). Both match the solutions of equation B (purple).
