Suppose that cos(t) = 2/3. Find the exact value of sec(t).

1 answer:

3 0

Secant(sec) = $\frac{1}{cos}$

So if cos(t) = $\frac{2}{3}$ , $\frac{1}{cos(t)}$ = $\frac{3}{2}$ .

Once again, since secant(sec) = $\frac{1}{cos}$ :

Sec(t)= $\frac{3}{2}$ .

laiz [17]

Given:

The two functions are:

$g(b)=5b-9$

$h(b)=(b-1)^2$

To find:

The value of $(h\circ g)(-6)$ .

Solution:

We have,

$g(b)=5b-9$

$h(b)=(b-1)^2$

We know that,

$(h\circ g)(b)=h(g(b))$

$(h\circ g)(b)=h(5b-9)$

$(h\circ g)(b)=[(5b-9)-1]^2$

$(h\circ g)(b)=[5b-10]^2$

Putting $b=-6$ , we get

$(h\circ g)(-6)=[5(-6)-10]^2$

$(h\circ g)(-6)=[-39-10]^2$

$(h\circ g)(-6)=[-49]^2$

$(h\circ g)(-6)=2401$

Therefore, the value of $(h\circ g)(-6)$ is 2401.

{x+2y+2z=0
{2x+y+z=3
{x-3y-z=1

{x+2y+2z=0
-
{4x+2y+2z=6
{-3x=-6 → x=2

{-3y-z=-1
+
{y+z=-1
{-2y=-2 → y=1

{2+2+2z=0 → 2z=-4 → z=-2
Final triple is
(2; 1; -2)
