The radian measure of an angle that is 25º 47' 31'' is D. .45 radians. This is the way how I've got the answer:
<span>25.7919*(pi/180) = 0.45 (approximately)</span>
So let f(x) = x^(2/3)
<span>Then let f'(x) = 2/3 x^(-1/3) = 2 / (3x^(1/3)) </span>
<span>When x = 8, </span>
<span>f(8) = 8^(2/3) = 4 </span>
<span>f'(8) = 2 / (3*8^(1/3)) = 1/3 </span>
<span>So near x = 8, the linear approximation is </span>
<span>f(x) ≈ f(8) + f'(8) (x - 8) </span>
<span>f(x) ≈ 4 + 1/3 (x - 8) </span>
<span>So the linear approximation for x = 8.03 is... </span>
<span>f(8.03) ≈ 4 + 1/3 (8.03 - 8) </span>
<span>f(8.03) ≈ 4 + 1/3 (0.03) </span>
<span>f(8.03) ≈ 4.01 </span>
<span>8.03^(2/3) ≈ 4.01 </span>
6 pounds.
First, find the amount she spent. 70 - 18.88 = 51.12
Now, just divide 51.12 by the cost per pound. 51.12 / 8.52 = 6
So, Karen purchased 6 pounds of coffee.

Answer:
x=18
Step-by-step explanation:
if x/6=3, the you can use the mulitplication property of equations to solve. so multiply each side by 6. it will eliminate the fraction on the left side of the equal side, leaving you with x and then 6x3=18, therefore
x=18
Answer: 2/3
