Answer:
First, you would need to find 7% of $64.99 which can be calculated like this:
64.99 x 0.07 = 4.55, this means that the sales tax on the boots is $4.55.
Step-by-step explanation:
4/3-1/2
=8-3/6
=5/6
thanks for the question
The APR is the annual percentage rate
therefore the APR is 1.5x12=18%
Answer:
Area of a triangle is :
it's given that ;
base = 10 m
height = 16 cm
Therefore, the area of triangle is 80 m²
Step-by-step explanation:
F(x) = x - 2sinx
To find for what values of x graph has tangents we need to differentiate function f(x).
f'(x) = 1-2cosx
Now, if we want to have horizontal tangents we need to make function f'(x) equal to 0 because at minimum or maximum of function f(x) tangent is horizontal.
1-2cosx = 0
cosx = 1/2
x = pi/3 + 2*n*pi and
x = -pi/3 + 2*n*pi
Explanation: cosx = 1/2 for both 60° and -60°. If we make one circle cosx will be equal to 1/2 for 420 and 300 degrees. Writing degrees in radians (using pi) we can write formulas above where 2*pi represents one full circle and n is an integer which represents how many circles we made.
