what is the domain of the function s=-4r^2 if the range is s <_ 0

Answer:

r≤0

Step-by-step explanation:

if the range is s≤0, (that means the value of s is all negative integers &0) to find the domain we have to replace that some negative integers &0.

we can replace some values of s as the following

s=‒4(0)^2 s=‒4(‒1)^2

=‒4(0) =‒4(1)

=0 =‒4

s=‒4(‒2)^2 s=‒4(‒3)^2

=‒4(4) =‒4(9)

=‒16 =‒36

so we can understand easly that the domain is negative integer&0,it can't be positive because the square of any integer is positive.

therefore the answer is r≤0

i think &i hope it is clear.

The domain is the set of values for which the given function is defined. The domain of the function s=-4r² if the range is s≤0 is r∈R. The correct option is B.

For the given function s=-4r², the domain of the function when s≤0 will be all the real numbers. This is because, for any value of r whether it is positive or negative, the value of r² will be positive, but at the same time this quantity is needed to be multiplied by -4.

Thus, the result of -4r² will be always negative, which is less than zero.

Hence, the domain of the function s=-4r² if the range is s ≤0 is r∈R.

_____________
2x = 14, - 5x and 5x will canceled out because it is equal to 0

Step 2: 2x = 14, Multiply both sides by 2

2x (2) = 12 (2)
x = 24
Step 3: Final Answer: x = 24

Eagletrons are all electric cars produced by Mogul motors. One of the concernsof Mogul is that the Eagletrons be capable of achieving appropriate maximumspeeds. To monitor this, Mogul executives take samples of 8 Eagletrons at atime. For each sample, they determine the average maximum speed and the rangeof the maximum speeds within the sample. They repeat this with 35 samples toobtain 35 sample means and 35 ranges. They find that the average sample mean is88.50 mph and the average range is 3.25 mph. Using these results, theexecutives decide to establish an R chart. They would like this chart to beestablished so that when it shows that the range of a sample is not within thecontrol limits, there is only approximately a .0027 probability that this is dueto natural variation. What will the upper control limit (UCL) and the lowercontrol limit (LCL) in this chart?

Trying to confirm that what I came up with is correct.

So, I have a question if anyone can answer soon.

The question: Jill jumped 6 1/3 feet in the long jump. Jill’s best friend jump 6 5/7 feet. How much farther did Jill’s best friend jump?

Now I know the answer is 8/21 but every-time I look up the decimal it’s like 0.3823. But, the next question that talked about if she jumped more than 6.5 feet then the seventh graders get fifty points. Now, I have tried to look up the answer cause I though I was missing something and it all has said the best friend jumped more than 6.5. How? If the decimal was like 0.3823.
