Answer:
Step-by-step explanation:
First of all, the equation of the circle is
Where the radius is 17 units long.
Now, we need to find the slope of the radius OP,
Then, we use the perpendicular rule
Next, we use the point-slope formula, with the slope we found and the point (8,15).
Therefore, the equation of the tangent line is
Answer:
Step-by-step explanation:
The average profit expression is for 1 piece of furniture
The amount of furniture is another expression
So we have to multiply both expressions to get the total profit.
(2x-2) (2x-2) = 4x^2 - 4x - 4x + 4
= 4x^2 - 8x + 4
Answer:
The ratio of the distance of Pluto and the earth to the Sun is 40.
Time taken by light to travel from Sun to Pluto is 5.3 hours.
Step-by-step explanation:
Distance between Earth an Sun = 93,000,000 miles
Time from Sun to Earth = 8 minutes
Distance beteen Pluto and Sun = 3.7 x 10^9 miles
The ratio of the distance between Pluto and Sun to the Earth and Sun is
Now let the time taken by the light to move from Sun to Pluto is t.
