Answer:
It is 55.85. that is the answer.
Answer:
Step-by-step explanation:
To find the best place to buy the video game, we need to find the price for each store, and see which is least. To do this, find the percents of each and subtract.
To find the percent, simply multiply your original number by a decimal version of the percent
Ex: 160* .4=64
155*.3=46.5
160*.2=32.
Then, subtract the amounts from each price.
160-64=96
155-46.5=108.5
160-32=128
Clearly, store a is the best place to buy the system.
Hope this helps!
Answer:
59
Step-by-step explanation:
![\sqrt{ {6}^{2} + {5}^{2} } = \sqrt{36 + 25} = \sqrt{61}](https://tex.z-dn.net/?f=%20%5Csqrt%7B%20%7B6%7D%5E%7B2%7D%20%20%2B%20%20%7B5%7D%5E%7B2%7D%20%7D%20%20%3D%20%20%5Csqrt%7B36%20%2B%2025%7D%20%20%3D%20%20%5Csqrt%7B61%7D%20)
![\cos(p) = \frac{4}{ \sqrt{61} }](https://tex.z-dn.net/?f=%20%5Ccos%28p%29%20%20%3D%20%20%5Cfrac%7B4%7D%7B%20%5Csqrt%7B61%7D%20%7D%20)
![p = {cos}^{ - 1} \frac{4}{ \sqrt{61} } = 59](https://tex.z-dn.net/?f=p%20%3D%20%20%7Bcos%7D%5E%7B%20-%201%7D%20%20%5Cfrac%7B4%7D%7B%20%5Csqrt%7B61%7D%20%7D%20%20%3D%2059)
Make sure your calculator is in degree mode.
Answer:
sin x = 0 at x = 0°, 180°, and 360°
Step-by-step explanation:
What we are going to do with this problem is combine all the like terms.
so to begin, we notice that there are two numbers with a^2 involved, and two numbers with an a.
thus:
8
![a^{2}](https://tex.z-dn.net/?f=%20a%5E%7B2%7D%20)
+(-3
![a^{2}](https://tex.z-dn.net/?f=%20a%5E%7B2%7D%20)
is going to equal
5
because adding a negative is just like subtracting.
then we move on to (6a)-(2a) giving us 4a
5 is the only term that stays the same because there are no other similar terms.
last but not least, put the equation together!
answer: 5
+4a+5
