Find the missing side. Write as an exact answer in simplest radical form.
Eddi Din [679]

Answer:

b = 36

Step-by-step explanation:

Assuming this is a right triangle with hypotenuse = c and legs a and b

Then using Pythagoras' identity.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

a² + b² = c², and substituting values

15² + b² = 39², that is

225 + b² = 1521 ( subtract 225 from both sides )

b² = 1296 ( take the square root of both sides )

b = \sqrt{1296} = 36

Integral (x pangkat 3 - cos x) dx
ch4aika [34]

You can break the integral of a sum/difference into the sum/difference of the integrals:


\int (x^3-\cos(x))\;dx = \int x^3\; dx - \int \cos(x)\; dx


The first integral can be solved using the power rule for integrations:


\int x^n\; dx = \frac{x^{n+1}}{n+1} \implies \int x^3\; dx = \frac{x^4}{4}


As for the second, remember the chain of derivation of trigonometric functions:


\sin(x) \to \cos(x) \to -\sin(x) \to -\cos(x) \to \sin(x) \ldots


The integration chain is the same, but it follows the opposite direction: the integral of the cosine function is the sine function. So, you have


- \int \cos(x)\; dx = -\sin(x)


Since this is an indefinite integral, we must add the generic costant to the answer:


\frac{x^4}{4} -\sin(x) + C

Using substitution how do you solve -5x+y=-3 3x-8y=24
levacccp [35]
-5x+y=-3. (1) isolate y 1.First isolate a variable.( I isolated y because it was already isolated)
3x-8y=24. (2). 2.Then substitute that into the other equation
—————. 3. Then solve for X
Sub y=5x-3 into (2). 4. Then substitute X into one of the equations
5. Then solve for Y and ta-da you find the answer.
3x-8(5x-3)=24.
3x-40x+24=24. Hope this helped! :)
3x-40x=24-24
-37x=0
X=0
——————
Sub x=0 into (1)

-5(0)+y=-3
Y=-3

.: (0,-3)
