Answer:
The answer is D: -y^4
Step-by-step explanation:
(-1/y^-4) = -1(y^4)/1 = -y^4
As a ratio, 5:86 represents students to teachers
We can set up the equation as 5/86=x/9460
Multiply 9460 to both sides
5x9460/86=x
47300/86=x
x=550
There are 550 professors
Answer:
I think it's G
Step-by-step explanation:
Since a=8 root 3=8×3=24cm
Yh so I multiplied the 24cm by 12cm
12cm×24cm=288cm squared
and the square root of 288cm is 96 root 3 cm squared
-4(-4) = positive 16
Positive 16(-4) = -64
-64 is your answer
Answer:

Step-by-step explanation:
If AB = 5 , then AE = 5 [Radii of the same circle]
So,
AC = AE + EC
AC = 8+5
AC = 13 units
Now, Using Pythagorean theorem to find the missing side i.e. BD because tangent strikes the circle at 90 degrees making the triangle a right angled triangle

Where c = AC , a = BD and b = AB

169 = BD² + 25
Subtracting 25 to both sides
169 - 25 = BD²
BD² = 144
Taking square root on both sides
BD = 12 units
