An expression is defined as a set of numbers, variables, and mathematical operations. The second student is correct.

<h3>What is an Expression?</h3>

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

Given One student simplified x⁵ + x⁵ to x¹⁰. The second student simplified x⁵+x⁵ to 2x⁵. Since the simplification of (x⁵+x⁵) is equal to 2x⁵. Therefore, the second student is correct.

kelly is using a bucket to fill up a barrel with water from a well. The barrel holds 25.5 liters.the bucket holds 800 millileter
SVEN [57.7K]
To determine how much of the barrel is left to fill, you must subtract the amount of water already in it from the total mass of the bucket. 

25.5 - 5.2 = 20.3 Litres  

In order to the fill the entire barrel, Kelly must collect 20.3 Litres of water. You must then covert the measurement from litres to millilitres so that the bucket and barrel are measured in the same units. 

20.3L = 20300mL

You must then divide the amount of space left by the mass of the bucket. This will determine the least number of buckets needed to fill the barrel. 

20300 <span>÷ 800 = 25.375 

That means the you would have to do a minimum on 25.375 buckets to fill the barrel, or 26. 

Hope this helps :) </span>

f\left(\dfrac\beta2\right)=\sin\dfrac\beta2

Recall the half-angle identity:

\sin^2\dfrac\beta2=\dfrac{1-\cos\beta}2\implies\sin\dfrac\beta2=\pm\sqrt{\dfrac{1-\cos\beta}2}

So in order to find f\left(\dfrac\beta2\right), we only need to know the value of \cos\beta. But there are two possible values. To decide which to take, we use the given information: we know that \beta lies in quadrant III, which means \pi, so \dfrac\pi2, which places \dfrac\beta2 in quadrant II. In this quadrant, the sine of angle is positive, and so

\sin\dfrac\beta2=\sqrt{\dfrac{1-\cos\beta}2}

\beta is an angle of a ray whose terminal point, \left(-\dfrac13,y\right) lies on the circle x^2+y^2=1. The x-coordinate is all we need to know in order to find that \cos\beta=-\dfrac13. So,

\sin\dfrac\beta2=\sqrt{\dfrac{1-\left(-\frac13\right)}2}=\sqrt{\dfrac46}=\dfrac{\sqrt2}{\sqrt3}=\dfrac{\sqrt6}3
