Letter D
1-sin^2(x) = cos^2(x)
= sin^2(x)/cos^2(x)
= tan^2(x)
Answer:
-3/2
Step-by-step explanation:
the slope of a line is expressed as ratio y/x showing how many units y changes, when x changes a certain number of units.
so, going from A to B, x changes 4 units (from -3 to +1), and y changes 6 units (down, from +3 to -3). that makes the y change negative.
so, the slope is
-6/4 = -3/2

3x-5y=20 the answer is y= 4x+-1/3
Answer:
Step-by-step explanation:
Use the equation 2,000 = 16,000(1-r)^t to solve for t;
2000 = 16000(1-0.35)^t
Divide both sides by 16000
2000/16000 = 0.65^t
0.125 =0.65^t
Introduce logarithm on both sides;
<em>ln</em> 0.125 = t <em>ln</em> 0.65
Divide both sides by <em>ln</em> 0.65;
(<em>ln</em> 0.125) / (<em>ln</em> 0.65) = t
-2.07944/ -0.4308 = t
4.827 = t
t= 5 (as a whole number)
Therefore, the car is about 5 years old.
