Plzzzzzzzz helpe out

Dvinal [7]

Answer:

$\frac{cos-sin^{2}+1 }{sin(1+cos)}\\\\=\frac{cos - sin^{2}+sin^{2}+cos^{2} }{sin(1+cos)}\\\\=\frac{cos+cos^{2} }{sin(1+cos)}\\\\=\frac{cos(1+cos)}{sin(1+cos)}\\\\=\frac{cos}{sin}\\\\=cot$

( 1 = sin² + cos²)

the temperature at noon was -27 degrees . the temperature increased by 13 degrees by 2pm . what was the temperature at 2pm

Aleks [24]

First, you would create an equation for this problem.
-27 + 13

Now, all you would have to do is solve it.
-27 + 13 = -14

By 2 pm the temperature was -14 degrees.

I hope this helps!

Which function is equivalent to <br> y = 3(x + 2)2 + 7 ?

Troyanec [42]

Step-by-step explanation:

<u>Our function:</u>

$y = 3(x + 2)^{2} + 7$

<u>Include the exponent:</u>

$y = 3(x^{2} + 4) + 7$

<u>Use the Distributive Property:</u>

$y = 3 {x}^{2} + 12 + 7$

<u>Add:</u>

$\boxed{y = 3 {x}^{2} + 19}$

Suppose that two electronic components in the guidance system for a missile operate independently and that each has a length of

lord [1]

Answer:

The probability density function for the average length of life of the two components is $f(x) = 0.5e^{-0.5x}$

Step-by-step explanation:

Exponential distribution:

The exponential probability distribution, with mean m, is described by the following probability density:

$f(x) = \mu e^{-\mu x}$

In which $\mu = \frac{1}{m}$ is the decay parameter.

Each missile has a length of life governed by the exponential distribution with mean 1 (with measurements in hundreds of hours). Find the probability density function for the average length of life of the two components.

2, each with mean 1 means that $m = 2*1 = 2, \mu = \frac{1}{2} = 0.5$

So the probability density function is:

$f(x) = 0.5e^{-0.5x}$
