Determine the equation of straight line which passes through the point (a, b)and perpendicular to ax+by=5

Citrus2011 [14]

Answer:

$y=\frac{b}{a} x.$

Step-by-step explanation:

1) if the required straight line is 'l', the given point is A(a;b), then the required equation of line can be written in form:

$\frac{x-a}{x_1-a} =\frac{y-b}{y_1-b},$

where (x₁;y₁) is other point B, which belongs to the 'l';

2) from the equation it is possible to detect the coordinates of the perpendicular, they are (x₁-a;y₁-b);

3) if the given perpendicular is ax+by=5, then the coordinates of the vector (a;b) are coordinates of the vector, which belongs to the required line 'l', and then: x₁-a=a and y₁-b=b;

4) if to substitute the a=x₁-a and b=y₁-b into the required equation of line 'l', then:

$\frac{x-a}{a} =\frac{y-b}{b};$

5) finally, the equation is: ay=bx, or y=b/a *x (slope-interception form).

note: the suggested solution is not the only way.

Bethanie's daily drive to work involves driving through some steep terrain. She came up with the following graph to model her el

shtirl [24]

Answer:

Option D.

Step-by-step explanation:

-If the attached graph shows the distance above sea level to which Bethanie's leads as a function of time, then we can observe that after having elapsed 8 minutes Bethanie's is a distance of 0 from sea level.

The graph shows that the value of B(t) is always less than 1 during the 8 minutes of travel.

-On the other hand, the function $M(t) = t ^ 3-6t ^ 2 + 11t-6$ that models the distance above sea level that Mike drives as a function of time, shows us that after 3 minutes the distance M(t) begins to increase rapidly until at t = 8 minutes:
