Answer:
A
Step-by-step explanation:
Let x = Tan
dx = sec²d
sqrt(1 + ) = sec
So I = Tan(theta) * sec(theta)
but Tan(theta) = sin(theta) / cos(theta) = sin(theta)*sec(theta)
So I = integral sin(theta)*sec^2(theta) d theta
Answer A
Answer:
D)
A = x(x + 4)
Step-by-step explanation:
Area of a rectangular map = width × length
Length of the rectangular map = (x + 4) miles
Width of the rectangular map = x miles
Area of a rectangular map = width × length
= x(x + 4)
= x² + 4x
D)
A = x(x + 4)
Answer:
There is no solution, y-int of one line is positive
Step-by-step explanation:
There is no solution because there are no shared points between both lines, and the y intercept of the blue line is positive, because it is above the x-axis.
Answer:
A =153.86
Step-by-step explanation:
The area of a circle is given by
A = pi r^2
We know pi = 3.14 and the radius is 7
A = 3.14 * 7^2
A =153.86
