Lana71 [14]

Answer:

dV(t)/dt = kV(t)

Step-by-step explanation:

Since the rate of change of the car’s value in dollars per year dV(t)/dt is proportional to the car’s value V(t), ten

dV(t)/dt ∝ V(t)

dV(t)/dt = kV(t)

A manufacturer earns Rs4500 in the first month and Rs 6000 in second month. On plotting these points a manufacturer observes a l

UkoKoshka [18]

Answer:

$f(x) = 1500x +3000$

Step-by-step explanation:

Given

Represent the months with x and the earnings with y.

So:

$(x_1,y_1) = (1,4500)$

$(x_2,y_2) = (2,6000)$

Required

Determine the linear function

First, calculate slope (m)

$m = \frac{y_2 - y_1}{x_2 - x_1}$

$m = \frac{6000 - 4500}{2 - 1}$

$m = \frac{1500}{1}$

$m = 1500$

The equation is then calculated using:

$y = m(x - x_1) + y_1$

$y = 1500(x - 1) + 4500$

$y = 1500x - 1500 + 4500$

$y = 1500x +3000$

As a function, we have:

$f(x) = 1500x +3000$

Circle O is shown. 2 tangents intersect at a point outside of the circle which is labeled Satellite. The angle formed is 20 degr

TiliK225 [7]

Answer:

The arc measure, x, that the satellite can see is 160°

Step-by-step explanation:

Given that the two tangents intersect at a point outside the with circle center O

The angle formed between between the two tangent = 20°

The first arc formed is measured as x°, which is the arc opposite the point where the two tangents meet = The arc the satellite can see

The angle x is given by the relationship;

x = 2 × (90 - v/2)

Where;

v = The angle formed at the point where the two tangent meet = 20°

Therefore;

x = 2 × (90 - 20/2) = 2 × (90 - 10) = 2 × 80 = 160°

The arc measure, x, that the satellite can see = 160°.
