Use the unit circle to find sec (-90)
andreyandreev [35.5K]

Using the unit circle, you can visualise the secant as follows:

  1. Draw the vertical line passing trough (1,0)
  2. Extend the radius until it meets this line at point P
  3. The length of OP is the secant of your angle.

Since -90 means that the radius points downwards, it means that the radius is vertical as well, and thus it never meets the vertical line through (1,0).

Thus, the secant is not defined at -90.

In fact, if we switch back to the function notation, we can confirm this claim, since we have

\sec(x)=\dfrac{1}{\cos(x)}\implies \sec(-90)=\dfrac{1}{\cos(-90)}=\dfrac{1}{0}

which is undefined.

Answer:

70, I think

Step-by-step explanation:

f(10)= -10^2- 3(10)

f(10)= 100-30

f(10) = 70

PLZ HELP ME my teacher be buggin
Bumek [7]

2.

We have a transversal across parallel lines so we get the usual array of congruent and supplementary angles.  We just have to figure out which is which, and the diagram, even though not to scale, makes it pretty obvious.

Angle x isn't the same as the 40° angle so it must be its supplement.

Answer: C 140°

3.

r=1.2, h=2.9, V = (1/3) πr²h

Nothing hard here, we just plug in the numbers,

V = (1/3) π (1.2)² (2.9) ≈ 4.37310

Answer: B. 4.4 cubic inches

4.

Dilation by .5 makes a similar triangle, and reflection is an isomorphism (i.e. it doesn't change the size or shape) so the answer is

Answer: B similar not congruent

5.

The corresponding interior and exterior angles of a triangle form a linear pair, so supplementary angles. x=180-110 = 70°

Answer: A 70°

There are 350 members in a swimming club. Of them, 2/7 are new members. Of the new members, 3/10 are females. How many new femal
djyliett [7]
350 / 7 = 50
50 * 2 = 100

100 new members

100 / 10 = 10
10 * 3 = 30

30 are new female members
