If sin(θ -π/2) = 0.73.. find cos (-θ) plz explain how to solve

Temka [501]

Answer:

$cos(-\theta) = -0.73$

Step-by-step explanation:

It is given that:

$sin(\theta -\dfrac{\pi}{2}) = 0.73$

Formula to be used:

$1.\ sin(-x) = -sinx\\2.\ sin(\dfrac{\pi}{2}-x) = cosx\\3.\ cos(-x) = cosx$

Using Formula (1) written above:

$\Rightarrow sin (\theta - \dfrac{\pi}{2})=sin(-(\dfrac{\pi}{2}-\theta ))\\\Rightarrow -sin(\dfrac{\pi}{2}-\theta)$

Now, using Formula (2) written above:

$\Rightarrow -sin(\dfrac{\pi}{2}-\theta) = -cos \theta$

So, we can say that:

$sin(\theta -\dfrac{\pi}{2}) = -cos\theta = 0.73 ...... (1)$

We have to find the value of $cos(-\theta)$ .

Using Formula (3) written above:

$cos(-\theta) = cos\theta$

So, ultimately we need to find the value of $cos\theta$

Using equation (1):

$-cos\theta = 0.73\\\Rightarrow cos\theta = -0.73$

So, the answer is $cos(-\theta) = -0.73$ .

Answer:

$x < -20$

Step-by-step explanation:

Given the following question:

$x+8 < -12$

In order to solve one step inequalities, we solve how we would normally solve a one-step equation and then graph the answer on a number line.

$x+8 < -12$
$8-8=0$
$-12-8=-20$
$x < -20$

Now to graph the inequality on a number line, keep a few things in mind:
. x is less than -20 which means the line would go the opposite way of the negative 20.
. < is a greater than sign, not a greater than or equal sign (≤) so the number line will have a open point.
. The number line will have a point on -20.

Hope this helps.
