Answer:

Step-by-step explanation:

To be a function x can't repeat with a different y so in a every element of x is mapped to a different y so it is a function.

For choice B, -4 is paired with both 7 and 8 so it is not a function.

Choice C is a function since each x is paired with a different y.

For any nonnegative real number.
frutty [35]

Answer:

A

Step-by-step explanation:

We know that \sqrt{b}=b^{1/2}.

We also know that (a^b)^c=a^{bc}.

We can combine these facts to get (\sqrt{b})^2=(b^{1/2})^2=b^{1/2*2}=b^{1}=b.

So, the answer is \boxed{A} and we're done!

<em>Note: the non-negative part or the equation comes from the fact that you assume the square root of a negative number doesn't exist. You will change this assumption later in the year, or in further years.</em>

Given R = 10 and theta = 1.15 pi, find the Cartesian coordinates. ​
love history [14]

We have been given that r=10 and \theta =1.15\pi. We are asked to find the Cartesian coordinates.

We know that x=r\cdot \text{cos}(\theta) and y=r\cdot \text{sin}(\theta).  

Let us convert polar coordinates to Cartesian coordinates using above formula.

x=10\cdot \text{cos}(1.15\pi)

x=10\cdot (-0.891006524188)

x=-8.91006524188

Round to nearest hundredths:

x\approx -8.91

y=10\cdot \text{sin}(1.15\pi)

y=10\cdot (-0.45399049974)

y=-4.5399049974

Round to nearest hundredths:

y\approx -4.54

Therefore, the Cartesian coordinates will be (-8.91,-4.54) and option 'b' is the correct choice.

The indoor pool has a temperature of 24 The outdoor pool has a temperature of 23 Which pool has a higher temperature And which p
Ludmilka [50]

Answer:

The indoor pool has a higher temperature and also has the greatest absolute value.

Step-by-step explanation:

The indoor pool has a higher temperature becasue 24 is greater than 23.  It also has a bigger absolute value because the absolute value how much a number is from 0.

So the absolute value of 24 is 24.

The absolute value of 23 is 23.

24 is greater so the indoor pool also has a bigger absolute value.
