TIMED QUESTION Which are the roots of the quadratic function f(b) = b2 – 75? Select TWO options.
Setler [38]

Answer:

b=5\sqrt{3} (b = 5 StartRoot 3 EndRoot)

and

b=-5\sqrt{3} (b = Negative 5 StartRoot 3 EndRoot)

Step-by-step explanation:

we have

f(b)=b^{2}-75

we know that

The roots of the quadratic function are the values of x when the value of the function is equal to zero

so

For f(b)=0

b^{2}-75=0

Solve for b

Adds 75 both sides

b^{2}=75

take square root both sides

b=(+/-)\sqrt{75}

Simplify

b=(+/-)5\sqrt{3}

therefore

b=5\sqrt{3} (b = 5 StartRoot 3 EndRoot)

and

b=-5\sqrt{3} (b = Negative 5 StartRoot 3 EndRoot)

Mean absolute deviation of 75, 89, 145, 85, 80, 92, 104, 90, 100?
Mama L [17]
First, compute the mean: m=\frac{75+89+145+85+80+92+104+90+100}9=\frac{860}9=95.555

Next compute the absolute deviations for each datapoint:
|75-95.555|=20.555
|89-95.555|=6.555
|145-95.555|=49.445
|85-95.555|=10.555
|80-95.555|=15.555
|92-95.555|=3.555
|104-95.555|=8.445
|90-95.555|=5.555
|100-95.555|=4.445

Next we'll take the mean of these deviations: \frac{20.555+6.555+49.445+10.555+15.555+3.555+8.445+5.555+4.445}9=\frac{124.665}9=13.8517

The mean absolute deviation of your data is 13.8517

PLSSS HELP IF YOU TURLY KNOW THISS
Alexandra [31]

Hello there! :)

6^8*6^3

Here, we have the same base, so we add the powers:

6^11

Now, our expression looks like this:

6^11/6^5

Subtract the powers now that we divide:

6^6

So the missing exponent is 6. Hope it helps!

If you have any query, feel free to ask!
