How will you know whether a solution is a percent increase or a percent decrease?
chubhunter [2.5K]

Step-by-step explanation:

First, work out the difference (decrease) between the two numbers you are comparing. Next, divide the decrease by the original number and multiply the answer by 100. If the answer is a negative number, this is a percentage increase.

A^2/5 x a^-3 in the form a^n
leonid [27]

Answer:

a^(-2 3/5)

Step-by-step explanation:

When you multiply two numbers together with the same base, you can add the two exponents together. In this case, a^{\frac{2}{5}}\cdot a^{-3}=a^{-2\frac{3}{5}}. Hope this helps!

I need help with numbers 15 and 18!!! what does x equal? help asap!!
Sav [38]

Answer:

15. x = 112 degrees

18. x = 120 degrees

Step-by-step explanation:

<u>15.</u>

A triangle's angles always equal 180 degrees so we can find the two unknown angles by subtracting 44 from 180 and then dividing it by 2.

2a + 44 = 180

2a = 136

a = 68

Each unknown angle equals 68 degrees. The line from 44 degrees to x degrees segments a line that has a 180 degree angle so we can subtract 68 from 180 to get x.

x + 68 = 180

x = 112

<u>18.</u>

We can use the same concept here but now every angle equals each other so we can divide 180 by 3 to get the measure of those angles.

3a = 180

a = 60

Now we do the same thing as last time to find x.

x + 60 = 180

x = 120

Suppose theta= 11pi/12. How do you use the sum identity to find the exact value of sin theta?
SIZIF [17.4K]
The better way is, first we have to find the equivalent in degrees

2\pi=360\º

\frac{11\pi}{12}=345\º

now we can change this value to -15\º

how do we get an angle like this?!

30\º-45\º=-15\º

then

sin(30\º-45\º)=sin(30\º)*cos(45\º)-sin(45\º)*cos(30\º)

\begin{Bmatrix}sin(30\º)&=&\frac{1}{2}\\\\sin(45\º)&=&cos(45\º)&=&\frac{\sqrt{2}}{2}}\end{matrix}\\\\cos(30\º)&=&\frac{\sqrt{3}}{2}\end{matrix}

now we replace this values

sin(-15\º)=\frac{1}{2}*\frac{\sqrt{2}}{2}-\frac{\sqrt{2}}{2}*\frac{\sqrt{3}}{2}

sin(-15\º)=\frac{\sqrt{2}}{4}-\frac{\sqrt{6}}{4}

\boxed{\boxed{sin(-15\º)=sin(345\º)=\frac{\sqrt{2}-\sqrt{6}}{4}}}
