Answer:

The first equation: f = negative 2

The second equation: p = 2

Step-by-step explanation:

do you have to subtract from both sides then isolate the variable by dividing.

Simplify the expression.

Marizza181 [45]

$\bf \textit{Cofunction Identities}
\\ \quad \\
sin\left(\frac{\pi}{2}-{{ \theta}}\right)=cos({{ \theta}})\qquad 
\boxed{cos\left(\frac{\pi}{2}-{{ \theta}}\right)=sin({{ \theta}})}
\\ \quad \\ \quad \\
tan\left(\frac{\pi}{2}-{{ \theta}}\right)=cot({{ \theta}})\qquad 
cot\left(\frac{\pi}{2}-{{ \theta}}\right)=tan({{ \theta}})
\\ \quad \\ \quad \\
sec\left(\frac{\pi}{2}-{{ \theta}}\right)=csc({{ \theta}})\qquad 
csc\left(\frac{\pi}{2}-{{ \theta}}\right)=sec({{ \theta}})$

$\bf \\\\
-------------------------------\\\\
sin^2(\theta)+cos^2(\theta)=1\implies cos^2(\theta)=1-sin^2(\theta )
\\\\\\
\boxed{cos(\theta )=\sqrt{1-sin^2(\theta )}}$

$\bf \\\\
-------------------------------\\\\
\cfrac{cos^2\left(\frac{\pi }{2}-x \right)}{\sqrt{1-sin^2(x)}}\implies \cfrac{\left[ cos\left(\frac{\pi }{2}-x \right)\right]^2}{cos(x)}\implies \cfrac{[sin(x)]^2}{cos(x)}\implies \cfrac{sin(x)sin(x)}{cos(x)}
\\\\\\
sin(x)\cdot \cfrac{sin(x)}{cos(x)}\implies sin(x)tan(x)$

To find the average of a student’s test scores, add the scores and divide by the number of tests. Suppose Ryan scored 85, 92, 88

Lilit [14]

X= (85+92+88+98)/4
The slash means to divide. So you’re making a fraction with all the scores on top and the number of scores on the bottom.

So like tell me the answer I think it’s like either 3 or 6a^9 but I’m not sure

Iteru [2.4K]

I'm not sure what you mean by 3 or 6a^9, since there are only variables in the photo, but we can try breaking it down.

Let's start with the bottom,

a^2 * a^3 would be a^5 because for exponents you add the exponents of what's multiplied (product rule)

Then using the quotient rule, where you subtract the exponents, a^5/a^5 = a^(5-5)

And anything to the 0th power is 1, so your answer should be 1

Hope that helps!
