If the rate of decay is 6% per year, that means the motorcycle retains 93% of its value every year. Because there are 12 months in a year, you can use the following equation: 
 x^12 = 0.94, 
 where x = the rate of decay each month, 12 = the number of months, and 0.94 = the retained value each year. Next, set a logarithmic function on each side as such: 
 LOG(x^12) = LOG(0.94) 
 When applying log functions, exponentials (like the 12 in the equation) are moved outside of the function like so: 
 LOG(x^12) = 12(LOG(x)) 
 Therefore, 
 12(LOG(x)) = LOG(0.94) = -0.0268721464 
 When you divide both sides by 12, the equation becomes 
 LOG(x) = -0.00223934553 
 Finally, remove the LOG from the left side by applying both sides of the each by 10^() as such: 
 10^(LOG(X)) = 10^(-0.00223934553)
 X = 0.994856987 
 Therefore, the motorcycle retains that 0.994856987 of its value every year. 
 1 - 0.994856987 = 0.005143 
 Expressed as a percentage, this value is 0.5143013%

ΔPQR has angle measurements of 80°, 50°, and 50°. What kind of triangle is ΔPQR?
trasher [3.6K]

Answer:

Isosceles Triangle; Acute Triangle

Step-by-step explanation:

Review your definitions of the different types of triangles:

acute triangle- a triangle that has three acute (less than 90 degrees) angles

obtuse triangle- a triangle that has an obtuse (greater than 90 degrees) angle.

right triangle- a triangle that had one right (90 degrees) angles

isosceles triangle- a triangle with two congruent sides and one unique side and angle.

equilateral triangle-  a triangle with three congruent sides and three congruent angles.

scalene triangle- a triangle with no congruent sides and no congruent angles.

With these definitions, we can classify ΔPQR as an isosceles acute triangle.

Subtract.<br> 5x – 6x+2<br> - 1-2x - x - 2)
adell [148]

Answer:

7x^2 -5x + 4

Step-by-step explanation:

5x^2 – 6x+2

- (-2x^2 - x - 2)

We got 5x^2 - (-2x^2) = 5x^2 + 2x^2 = 7x^2

-6x - (-x) = -6x + x = -5x

2 - (-2) = 2+2 = 4

So the equation would be 7x^2 -5x + 4

Hope this help :3
