Answer:
x = 6 , AC = [tex]\sqrt{89}[/tex]
Step-by-step explanation:
(3)
Tangents to a circle from an external point are congruent, then
4x - 9 = 15 ( add 9 to both sides )
4x = 24 ( divide both sides by 4 )
x = 6
(4)
the angle between a tangent and a radius at the point of contact is right , so
Δ ABC is a right triangle with hypotenuse AC
Using Pythagoras' identity in the right triangle
AC² = AB² + BC² = 5² + 8² = 25 + 64 = 89 ( square root both sides )
AC = [tex]\sqrt{89}[/tex] ≈ 9.4 ( to 1 dec. place )

What is the perimeter of this triangle?
A. 33 units
B. 36 units
C. 39 units
D. 42 units
Selecr the correct answer.
What is the value of x in the triangle?
Answer:
[tex]Isosceles \ triangle \ two \ sides\ are \ equal \\\\(3\sqrt{2})^{2} = x^2 + x^2\\9 \times 2 = 2x^2\\x^2 = 9\\x = 3[/tex]
The value of x, length of base is B) 3.
The answer must be the length of the base of the triangle. Since the two other angles are equal, the triangle is an isosceles right triangle. This means that the two shorter sides of the triangle are congruent.
We can use the Pythagorean theorem to find the length of the base of the triangle. The Pythagorean theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides. In this case, the hypotenuse is 3√2, so the square of the hypotenuse is 18. The other two sides of the triangle are congruent, so let the length of each side be x. The square of each side is x². Therefore, we can write the following equation:
18 = x² + x²
Solve for x:
2x² = 18
x² = 9
x = 3
Therefore, the length of the base of the triangle is 3. So the answer is B.

Each of the letters of the word ALABAMA are written on a piece of paper and then
put into a bag. A piece of paper is drawn at random. What is the theoretical
probability of NOT drawing an A?
Answer:
3/7
Step-by-step explanation:
There are 7 letters in ALABAMA. And there are 4 A's in ALABAMA. So if you're trying to not get an A then you would subtract 4 from 7. Which you would get 3/7 of the letters in ALABAMA are not A.

Answer:
t = 0.0475p
Step-by-step explanation:
From the options provided, the answer would be ...
t = 0.0475p
Lets say Tonia's paycheck is 25,000 she needs to pay 5% of this to her 401k, meaning she should have 95% left
25,000 * 0.95 = 23,750
Now, 5% of this remainder goes to income tax which would be...
23,750 * 0.05 = 1,187.5
Now if we use the formula and plug in 25,000 for p which is Tonia's paycheck we see that we get the same income tax amount. Therefore, we know it is the correct formula.
t = 0.0475 * 25000
t = 1,187.5

Twice a number increased by 12 is 20. What is the number?
Answer:
2x+12 = 20
x = 4
Step-by-step explanation:
Twice a number = 2x
increased by 12 = +12
Format:
2x + 12 = 20
Solve
Subtract 12 from both sides
2x + 12 - 12 = 20 - 12
2x = 8
divide both sides by 2
2x/2 = 8/2
x = 4

Answer:
B) 63 ft.
Step-by-step explanation:
To find how long it takes for a rotation, we need to find the circumference.
To do so, we use the formula 2(pi)r
To find the radius, we divide the diameter in half :
d = 20
r = d/2
r = 20 / 2
r = 10
Then, we plug that into the formula :
2(pi)10
Insert that into your calculator :
2(pi)10 = 62.83
Simplify :
62.83 = 63 ft.
