1 + sec^2(x)sin^2(x) = sec^2(x)
This becomes
1+tan^2(x) = sec^2(x) which is an identity
You could
1 + sin^2(x)/cos^2(x) = sec^2(x)
then
cos^2(x) + sin^2(x) = cos^2(x)sec^2(x)
1 = 1

Greeley [361]

Answer:

$12\dfrac{1}{8}\ feet$

Step-by-step explanation:

Sonya drops a marble while standing on a deck $7 \dfrac{7}{8}$ feet above the ground.

The marble falls $4 \dfrac{1}{4}$ feet from Sonya's hand to the deck, and then rolls and falls to the ground.

So, the ball falls $4 \dfrac{1}{4}$ feet from Sonya's hand to the deck and $7 \dfrac{7}{8}$ from the deck to the ground, in total

$4\dfrac{1}{4}+7\dfrac{7}{8}=4\dfrac{2}{8}+7\dfrac{7}{8}=(4+7)+\dfrac{2+7}{8}=11+\dfrac{9}{8}=11+1\dfrac{1}{8}=12\dfrac{1}{8}\ feet$

Y=4x+8x, Solve for x.<br><br> It's x=y/12, I just need to know how to work it out.

Scrat [10]

Step-by-step explanation:

<h2>Answer:-</h2>

$\tt{y = 4x+8x}$

First, we need to add up the x.

We know that 4+8 = 12, so

$\tt{4x+8x=12x}$

Now, equating it to y,

$\tt{y = 12x}$

Now, if I multiply $\tt{\dfrac{1}{12}}$ on both sides,

I get,

$\tt{\dfrac{y}{12}= \dfrac{\cancel{12}x}{\cancel{12}}}$

Now, as 12 got cancelled , I got the final answer as

$\boxed{\tt{x =\dfrac{y}{12}}}$

Hope it helps :)
