Answer:

The answer is

<h2> $\alpha = - \frac{1}{2}$ </h2>

Step-by-step explanation:

From the question

$\alpha$ is inversely proportional to $\beta$ is written as

<h2> $\alpha = \frac{k}{ \beta }$ </h2>

where k is the constant of proportionality

When

<h3> $\alpha$ = 4</h3><h3> $\beta$ = 9</h3>

Substituting the values into the formula

we have

$4 = \frac{k}{9}$

cross multiply

k = 4 × 9

k = 36

So the formula for the variation is

$\alpha = \frac{36}{ \beta } [/tex]when [tex]\beta$ = - 72

That's

$\alpha = \frac{36}{ - 72}$

Simplify

We have the final answer as

<h3> $\alpha = - \frac{ 1}{2}$ </h3>

Hope this helps you

(200 – 100) ÷ 4 + 5 what's the answer?

Softa [21]

Answer:

Step-by-step explanation:

PEMDAS

Parenthesis first which equals:100

Exponents are not in the problem so no calculations here:

Multiplication and Division sit on the same thing so think of PEMDAS like this

Its the same thing for Addition and Subtraction

Anyways there is no multiplication so skip that step and got too division 100 divided by 4=25

Then lastly Addition skip subtraction because you don't need and 25+5=30

__________ ____________

_________________________ Yep that's the answer 30.

Answer: $x=\frac{\pi}{4}\ or\ \frac{7\pi}{4}$

Step-by-step explanation:

Given equation is

$\sqrt{2}\cos x-1=0$

solving this

$\sqrt{2}\cos x=1\\\cos x=\frac{1}{\sqrt{2}}$

There can be two solution because $0$

$\cos x=\cos \frac{\pi }{4}\ or\ \cos (2\pi -\frac{\pi}{4})\\$

so, $x=\frac{\pi}{4}\ or\ \frac{7\pi}{4}$
