Answer:
The original price was $36,000.
It depreciates by $2,400 each year.
It’ll take 15 years for it to fully depreciate to zero
Step-by-step explanation:
To get how much the original price was, you replace x with 0 in the equation y=-2,400x+36,000 since it is 0 years at that time. When you do that, you get 36,000. It declines by $2,400 each year because the coefficient is 2,400x. To get the last part, you have to divide 36,000 by 2,400 and then you get 15.
Answer:
The answer for both blanks is lower and lower
Step-by-step explanation:
If you draw a number line, zero is in the middle and to the left you have negative numbers and to the right of zero will be the positive numbers. -6 is lower (left) of -1, -1 is left of positive 4. Hopes this helps!
Since the bases are the same, set the exponents equal to each other. X = 3
Answer:
Step-by-step explanation:
It is an obtuse triangle because one angle (5) takes up more than the sum of the other two (3+1=4).
The angles are:
5+3+1 = 9
Each angles is
5/9 * 180 = 100°
3/9 * 180 = 60°
1/9 * 180 = 20°
Total = 100+60+20 = 180 degrees.
Step-by-step explanation:
Using SOHCAHTOA
Second Question Explanation:
a. The base angles of an isosceles triangle are equal so angle ABC is also 32°
but the sum of angles in a triangle = 180° therefore
let angle CAB be x
b. If you share a triangle in half you get 2 right angles so I'll use SOHCAHTOA to find the length AB
First the base of the right angled triangle will be 20/2 = 10
c. To find the are we'll need to get the height first
using the right angled triangle With base 10cm and hypotenuse 11. 8 to find the height we'll use the Pythagorean theorem
now to find the area
