Answer:

x ≈ 31.0°

Step-by-step explanation:

Using the tangent ratio in the right triangle

tanx = \frac{opposite}{adjacent} = \frac{9}{15}, then

x = tan^{-1} (\frac{9}{15} ) ≈ 31.0° ( to 1 dec. place )

Find the coefficients of the terms below in the expansion of (uu+vv)8. Explain your reasoning.
gladu [14]

Answer:

Remember, the expansion of (u+v)^n=\sum_{k=0}^n\binom{n}{k}u^{n-k}v^k.

Then,

(u+v)^8=\sum_{k=0}^8\binom{8}{k}u^{8-k}v^k

a) since u^{8-k}=u^2, then 8-k=2, k=6. Therefore, the coefficient of u^2v^6 is \binom{8}{6}=28

b) u^3v^5=u^{8-k}v^k. Then k=5 and the coefficient of the term is \binom{8}{5}=56

c) u^4v^4, then k=4 and the coefficient of the term is \binom{8}{4}=70

PLEASE Solve Fast |x+2|<4
castortr0y [4]
|x + 2| < 4
As neither x or 2 are negative, the bars do not matter and can be eliminated. 
x + 2 < 4
Minus 2 from both sides, and because you subtracted, make sure to turn the 'less than' sign into a 'greater than' sign.
x > 2 is your answer

The sum of a number and two times a smaller number is 98. The bigger number is 22 less than three times the smaller number.
IgorC [24]
B>a 

<span>b=3a-22, b+2a=98, using b from the left in the right: </span>

<span>3a-22+2a=98 </span>

<span>5a-22=98 </span>

<span>5a=120 </span>

<span>a=24, and since b=3a-22, </span>

<span>b=50 </span>

<span>So the smaller number is 24 and the larger number is 50.</span>

let the space be x

x + 27 + x + 27 + x = 150

3x + 54 = 150

3x = 96

x= 32
