The cosine function is negative in 2nd and 3rd quadrants, So you know that you will have 2 solutions. One between pi/2 and pi, the other between pi and 3pi/2.
Refer to a unit circle to find that
Final Answer:
Area of polygon = (number of sides × length of one side × apothem)/2
Answer:
y-int=(0,40.5), x-int=(-18,0)
Step-by-step explanation: First you need to calculate the slope, which is 9/4. Then plug in a point into the y=mx+b, or slope intercept, equation using that slope.
9=(9/4)x+b. You'll get b is 40.5 which is y-int. Then plug in 0 for y and solve for x, which is your x int coordinate.
Answer:
p = 11145.96
Step-by-step explanation:
If x is an exponent and 1.01 its base then we are looking at a case of compound increments and the profit can be said to be earning compound interest at a rate of 1%. The profit of the store after 6 months is found by simply substituting x with 6 in the equation of p; p = 10500(1.01)^6
Y- (5+0)= 2+3(x-2)
Y-5=6(x-2)
y-5=6x-2
+5 +5
y=6x+7
6x+7=x-2
-x -7 -x -7
5x=9
9/5
the answer is 1.8
