solve for x
The radius is 10, so the diameter is 20. This means the parts of the diameter (the chord through the center P) to the left and right of the vertical chord have lengths 16 and 4, respectively.
Because the horizontal chord is a diameter, the vertical chord is cut in half, so its parts above and below the diameter both have length x.
Now, by the intersecting chord theorem,
16×4 = x × x
or
x ² = 64
so that
x = 8
The equation has a solution of x = 5.

What is 6 ( 8 + w). Use the distributive property to remove the parentheses.
Answer:
42 + 6w
Step-by-step explanation:
Basically,
6(8+w) is 6 x (8+w)
OR 6(8) + 6(w)
Hence 42 + 6w
help me please i dont know what to do
Answer:
x = 14.4
Step-by-step explanation:
First of all, the triangle has three sides, so let's use hero's formula to find the area.
A = √[p(p - a)(p - b)(p - c)]
Where;
a, b and c are the 3 given sides of the triangle and;
p = (a + b + c)/2
p = (18 + 30 + 24)/2
p = 72/2
p = 36
Thus;
A = √(36(36 - 18)(36 - 30)(36 - 24))
A = √46656
A = 216 Sq.units
Now, we also know from general formula of a triangle that;
A = ½bh
Where;
b is base and h is height
In the given image;
b = 30
h = x
Thus;
½ × 30 × x = 216
Rearranging, we have;
x = 216 × 2/30
x = 14.4
Can anyone help me out??

Answer:
p(1) = 6
Step-by-step explanation:
The basic idea is to put 1 wherever you see x. That gives you ...
p(1) = 2·1² +3·1 +1
The powers of x are all 1 when x=1, so the value of p(1) is just the sum of the coefficients:
p(1) = 2 + 3 + 1
p(1) = 6

A)
mZA = 950
B)
mZB = 65
C)
mZC = 959
D)
AD = 8
E)
DC = 12
Answer: I know that DC is 12 and AD=8 the others i dont know.
Step-by-step explanation:
This is because opposite sides of a parallelogram are parallel and congruent. therefore AB and DC are equal/congruent.

Write the equation of the quadratic function shown in the graph.
Answer:
Step-by-step explanation:
y = a(x-h)² + k, where (h,k) is the vertex.
vertex is clearly (0,0), so y = ax².
Plug in (3,3) and solve for a:
3 = a3²
a = ⅓
y = ⅓x²
Given the points A (-3, -1), B (1, 4) C (4, -1) what is the x coordinate of D, if ABCD is a parallelogram?
Given:
ABCD is a parallelogram, A(-3,-1), B(1,4), C(4,-1).
To find:
The x-coordinate of point D.
Solution:
Let the point D be (x,y).
We know that the diagonals of a parallelogram bisect each other. So, third midpoints are same.
Midpoint formula:
[tex]Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]
In parallelogram ABCD, AC and BD are two diagonals.
Midpoint of AC = Midpoint of BD
[tex]\left(\dfrac{-3+4}{2},\dfrac{-1+(-1)}{2}\right)=\left(\dfrac{1+x}{2},\dfrac{4+y}{2}\right)[/tex]
[tex]\left(\dfrac{1}{2},\dfrac{-2}{2}\right)=\left(\dfrac{1+x}{2},\dfrac{4+y}{2}\right)[/tex]
[tex]\left(\dfrac{1}{2},-1\right)=\left(\dfrac{1+x}{2},\dfrac{4+y}{2}\right)[/tex]
On comparing both sides, we get
[tex]\dfrac{1}{2}=\dfrac{1+x}{2}[/tex]
[tex]1=1+x[/tex]
[tex]1-1=x[/tex]
[tex]0=x[/tex]
Similarly,
[tex]-1=\dfrac{4+y}{2}[/tex]
[tex]-2=4+y[/tex]
[tex]-2-4=y[/tex]
[tex]-6=y[/tex]
The coordinates of point D are (0,-6).
Therefore, the x-coordinate of point D is 0.

A tennis tournament has 342 players. A single match involves 2 players. The winner of a match will play the winner of a match in the next round, whereas losers are eliminated from the tournament. The 2 players who have won all previous rounds play in the final game, and the winner wins the tournament. What is the total number of matches
Answer:
341 matches
Step-by-step explanation:
Given
[tex]Players = 342[/tex]
[tex]Match = 2\ players[/tex]
Required
Total number of matches.
The total number of matches is calculated by getting the number of matches in each round.
i.e.
[tex]Matches = \frac{Players}{2}[/tex]
So, we have:
Round 1
[tex]Matches = \frac{342}{2} = 171[/tex]
Round 2
[tex]Matches = \frac{171}{2} = 85\ R\ 1[/tex] [R 1 means remainder 1]
Round 3
[tex]Matches = \frac{85 + 1}{2} = \frac{86}{2} = 43[/tex]
[The remainder is added to each round]
Round 4
[tex]Matches = \frac{43}{2} = 21\ R\ 1[/tex]
Round 5
[tex]Matches = \frac{21+1}{2} = \frac{22}{2} = 11[/tex]
Round 6
[tex]Matches = \frac{11}{2} = 5\ R\ 1[/tex]
Round 7
[tex]Matches = \frac{5+1}{2} = \frac{6}{2} =3[/tex]
Round 8
[tex]Matches =\frac{3}{2} = 1 + 1[/tex]
Round 9
[tex]Matches = \frac{1+1}{2} =\frac{2}{2} = 1[/tex]
So, the total is:
[tex]Total = 171 + 85 + 43 +21 + 11 + 5 + 3 + 1+1[/tex]
[tex]Total = 341[/tex]

A rocket is launched from a tower. The height of the rocket, y in feet, is related to the time after launch, x in seconds, by the given equation. Using this equation, find out the time at which the rocket will reach its max, to the nearest 100th of a second.
y=-16x^2+161x+108
y=−16x
2
+161x+108
Answer:
5.03secs
Step-by-step explanation:
Given the height reached by the rocket expressed as;
y = -16x^2 + 161x + 108
The rocket reaches it max height when its velocity is zero
Velocity is expressed as;
V(x) = dy/dx = 0
dy/dx = -32x + 161
0 = -32x + 161
32x = 161
x = 161/32
x = 5.03
Hence it will take 5.03secs for the rocket to reach its maximum height
