Verify which of the following are identities. 1) 8 cos theta tan theta csc theta = 8

2) 13 sec^2 theta/cos^2 theta- tan^2 theta/ cos^2 theta=2

a. Only the first equation is an identity.
b. Only the second equation is an identity.
c. Both the equations are identities.
d. None of the equations are identities.

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)

0.85 or 85%

step-by-step explanation:

1) divide 23 by 27

2) round the decimal to the nearest 10

3) so your answer would be 0.85 or 85%

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

the answer is 62.8 cubic units
