what is the question for the problem.................
Answer:
x = 3
Step-by-step explanation:
Given a tangent and a secant from an external point to the circle, then
The square of the tangent is equal to the product of the secant's external part and the entire secant, that is
8(8 + 2x + 4) = 12²
8(12 + 2x) = 144 ( divide both sides by 8 )
12 + 2x = 18 ( subtract 12 from both sides )
2x = 6 ( divide both sides by 2 )
x = 3

3 * 3 = 9, that alone is bigger than 7.
3 * 3 + 1 = 10.
10 is bigger than 7.
Answer:
No
Step-by-step explanation:
To know if (3, 7) is a solution, plug 3 into the x and 7 into the y.
[tex](3)^{2} +1=7[/tex]
9 + 1 = 7
[tex]10\neq 7[/tex]
Therefore, (3, 7) is not a solution.

Answer:
x = 5.006 (approximate answer)
Step-by-step explanation:
According to the instructions, the two triangles are similar. Thus, we can write and solve an equation of ratios:
2x - 10 39
-------------- = ------------
78 169
x - 5 1
This reduces to ------------ = -----------
1 169
or (after cross-multiplication) 169x - 845 = 1
Solve for x: Add 845 to both sides, which results in 169x = 846
Dividing both sides by 169 results in x = 5.006 (approximate answer)

I need help! ABCD is a rectangle.
m<1 =
m<6 =
m<3 =
Answers
Answer:
m∠1 = 24°
m∠3 = 66°
m∠6 = 66°
Step-by-step explanation:
They are all near the corners of the rectangle
The corners always equal 90°
But as you can see, they are split down the middle by the X in the rectangle and we have only one angle to go off of; 24°
Since m∠1 is in the same triangle as that angle, and it looks exactly the same, the angle is exactly the same.
m∠3 and m∠6, if you look closely, are also the same. And as I said before, the corners always are 90°. Since 24° is taken from the neighboring triangle, the amount left is 66°, and remember, 24° + x° HAS to equal EXACTLY 90°. So
90 - 24 = 66
So both m∠3 and m∠6 = 66°

A drawbridge will sometimes open up to let boats and other water traffic pass
through. As it opens, the surface of the drawbridge raises above the level of
the roadway, as modeled by the function:
h+2
If the length of the drawbridge, r, is 25 meters, and the point Pis 16 meters
above the roadway, what is the distance d?
ANSWER IS 19.2
Answers
Answer:19.2
Step-by-step explanation:
The distance d is 19.2 meters.
What is Pythagoras theorem?The Pythagoras theorem states that if a triangle is right-angled (90 degrees), then the square of the hypotenuse is equal to the sum of the squares of the other two sides.
The model forms a right angle triangle with the model given as
r = [tex]\sqrt{h^{2} -d^{2} }[/tex]
From the question we were asked to find d when r = 25 meters and the
h = 16 meters.
Make d the subject of the formula
r = [tex]\sqrt{h^{2} -d^{2} }[/tex]
square both sides
r² = h² + d²
d² = r² - h²
where
r = 25 m
h = 16 m
d² = r² - h²
d² = 25² - 16²
d² = 625 - 256
d² = 369
square root both sides
d = [tex]\sqrt{369}[/tex]
d = 19.2 meters
Hence, the distance d is 19.2 meters.

Answers
Answer:

One tank is 25 buckets of water, so 2/5 of a tank is 10 buckets of water.
Answer:
62.5
Step-by-step explanation:
Let the capacity of 1 bucket = x.
Then, the capacity of tank = 25x.
New capacity of bucket = 2x/5
Required number of buckets = 25x / (2x/5)
= 25x * 5/2x
= 125/2 = 62.5

Radius of the Inner circle:
5.4 is the diameter so find the radius, divide by 2 = 2.7
Next, take pi (3.14) and multiply with the radius (2.7), and use a power of 2.
3.14(2.7)^2 = 22.8906. Then round to the nearest tenth: 23.
Radius of Outer circle:
2.2 is the diameter so find the radius, divide by 2 = 1.1
Next, take pi (3.14) and multiply with the radius (1.1), and use a power of 2.
3.14(1.1)^2 = 3.7994. Then round to the nearest tenth: 4.
Radius of the Inner circle: 23

To find:
The value of [tex]f(x+h)[/tex] in simplified form.
Solution:
We have,
[tex]f(x)=x^2+2x+1[/tex]
Putting [tex]x=x+h[/tex], we get
[tex]f(x+h)=(x+h)^2+2(x+h)+1[/tex]
[tex]f(x+h)=x^2+2xh+h^2+2x+2h+1[/tex]
[tex]f(x+h)=x^2+h^2+2xh+2x+2h+1[/tex]
