Is this right? find the equation of the tangent line to the graph of f(x)=sec(x) at the point (0,1). i took the derivative of secx and got secxtanx. then, i plugged in 0 for x and got 1x0, which is 0. y=0i think it's wrong, but i don't understand why.

What is the product? (x2+3y+7) [yy+1)

Which statement is true? the given sides and angles cannot be used to show similarity by either the sss or sas similarity theorems. the given sides and angles can be used to show similarity by the sss similarity theorem only. the given sides and angles can be used to show similarity by the sas similarity theorem only. the given sides and angles can be used to show similarity by both the sss and sas similarity theorems.

Solve the problem. a student earned grades of c, a, b, and a in four different courses. those courses had these corresponding numbers of credit hours: 4, 5, 1, and 5. the grading system assigns quality points to letter grades as follows: a = 4, b = 3, c = 2, d = 1, and f = 0. compute the grade point average (gpa) and round the result to two decimal places. 3.40 3.50 8.75 2.18
