Answer:
![2\sqrt[4]{3}](https://tex.z-dn.net/?f=2%5Csqrt%5B4%5D%7B3%7D)
Step-by-step explanation:
![48^\frac{1}{4} = \sqrt[4]{48}](https://tex.z-dn.net/?f=48%5E%5Cfrac%7B1%7D%7B4%7D%20%3D%20%5Csqrt%5B4%5D%7B48%7D)
Expanding
gives
which is equal to ![2\sqrt[4]{3}](https://tex.z-dn.net/?f=2%5Csqrt%5B4%5D%7B3%7D)
Answer:
0.16
Step-by-step explanation:
We can convert 4 / 25 to 16 / 100. Since 100 ends in 2 zeroes, we know that there will be 2 digits after the decimal point, therefore, the answer is 0.16.
Answer:
363 feet
Step-by-step explanation:
Tan(19) = 125/d
d = 125/tan(19)
d = 363.0263597
Answer:
first group x's with x's and y's with y's
then complete the squra with x's and y's
2x^2-8x+2y^2+10y+2=0
2(x^2-4x)+2(y^2+5y)+2=0
take 1/2 of linear coeficient and square
-4/2=-2, (-2)^2=4
5/2=2.5, 2.5^2=6.25
add that and negative inside
2(x^2-4x+4-4)+2(y^2+5y+6.25-6.25)+2=0
factor perfect squares
2((x-2)^2-4)+2((y+2.5)^2-6.25)+2=0
distribute
2(x-2)^2-8+2(y+2.5)^2-12.5+2=0
2(x-2)^2+2(y+2.5)^2-18.5=0
add 18.5 both sides
2(x-2)^2+2(y+2.5)^2=18.5
divide both sides by 2
(x-2)^2+(y+2.5)^2=9.25
that is a circle center (2,-2.5) with radius √9.25
