Answer:
B. 8
Step-by-step explanation:
The principal square root is another word for the positive square root. The square root of a number is the number that equals a given number when multiplied by itself.
In this case, 8*8 = 64. -8*-8 also equals 64, but we are looking for the principal square root here, so the only answer is 8.
Hope this helps!
Answer:
In geometry, Thales's theorem states that if A, B, and C are distinct points on a circle where the line AC is a diameter, then the angle ∠ABC is a right angle.
or in simpler words ;
angles formed in a <u>semicircle</u> that <u>includes </u>the <u>diameter</u> forms a 90 degree angle at the <u>angle opposite to the diamete</u>r. since the diameter divides it into two equal halves we reffer to it as a semicircle .
IF U STILL DIDNT UNDERSTAND , THEN :
- remember that when we talk about thales thorem , you should focus at some main things:
- angles are constructed inside a circle.
- the diameter is dividing the circle into two equal halves.(two semicircles)
- the angles formed are using the diameter as a base.
- so the thorem says that, in the semicircle formed by a diameter .
- when an angle is made opposite the base , it makes a 90 degree angle
or
- all angles made in a semicircle, form a 90 degree angle , opposte the diameter.

We will determine the roots of the given equation by rational root theorem.
Rational root theorem states:
"If P(x) is a polynomial with integer coefficients, then p is a factor of the constant term of P(x) and q is a factor of the leading coefficient of P(x).Then all the possible values of are the factors of the given polynomial".
Therefore, the given equation is:
The factors of the leading coefficient of = q =
The factors of the constant = p =
So, the possible values of .
Therefore, the roots of the given polynomial are .
The initial term of this geometric series is 4, and the common ratio is -1/2. The sum is given by
The sum is
approximately 2.66.

6 seconds
Step-by-step explanation:
h(x)=-(x-2)^2+16
We want h(x) to be 0 ( that is when the ball hits the ground)
0 = -(x-2)^2+16
Subtract 16 from each side
-16 = -(x-2)^2+16-16
-16 = -(x-2)^2
Divide by -1
16 = (x-2)^2
Take the square root of each side
sqrt(16) = sqrt((x-2)^2)
±4 = x-2
Add 2 to each side
2±4 = x-2+2
2±4 =x
2+4 = x 2-4 = x
6 =x -2 =x
Time cannot be negative so x=6
