The formula for the length of a polar curve is<span>∫<span>r2+(dr/dθ<span>)2 from a to b. 

In this case, dr/d</span></span></span>θ is the derivative of the function r which is equal to -cos (theta/2) * sin (theta/2)<span> which is equal to -1/2 cos theta. Since there are no limits defined, we leave the formula as it is but one can use the calculator if there are limits present already</span>

Jamal filled his gas tank and then use 7/16 of the tank for traveling to visit his grandfather. He then used 1/3 of the remainin
alisha [4.7K]

Answer:

The fraction of the tank is filled with gasoline is \frac{3}{8}.

Step-by-step explanation:

Consider the provided information.

Jamal filled his gas tank and then use 7/16 of the tank for traveling to visit his grandfather.

After his first traveling the amount of gas left can be calculated as:

1-\frac{7}{16}

\frac{16-7}{16}

\frac{9}{16}

He then used 1/3 of the remaining gas in the tank to run around town.

That means he left with 2/3 of gas.

\frac{9}{16}\times \frac{2}{3}

\frac{3}{8}

Hence, the fraction of the tank is filled with gasoline is \frac{3}{8}.

Simplify - root (9+y)^2 if y &lt;-10
nevsk [136]

Answer:

− √ ( 9 + y ) 2 > 1

Explanation:

− √ ( 9 + y ) 2 , where  y < − 10

Simplify the expression,

− √ ( 9 + y ) 2 = − ( 9 + y ) = − 9 − y

When  y < − 10 , − y > 10

Subtract  9  from both sides,

− 9 − y > 1  Hence,

− √ ( 9 + y ) 2 > 1

Does (3x+5)+5x+7=180?? and if it does what is the value of x?
Ostrovityanka [42]

Answer:  

x=21

Step-by-step explanation:

Let's solve your equation step-by-step.

3x+5+5x+7=180

Step 1: Simplify both sides of the equation.

3x+5+5x+7=180

(3x+5x)+(5+7)=180(Combine Like Terms)

8x+12=180

8x+12=180

Step 2: Subtract 12 from both sides.

8x+12−12=180−12

8x=168

Step 3: Divide both sides by 8.

8x /8 = 168 /8

x=21
