Answer:
[tex] BD \approx 2.6[/tex]
Step-by-step explanation:
By angle bisector theorem:
[tex] \frac{3.4}{BD} = \frac{6.5}{4.9} \\ \\ BD = \frac{3.4 \times 4.9}{6.5} \\ \\ BD = \frac{16.66}{6.5} \\ \\ BD = 2.56307692 \\ \\ BD \approx 2.6[/tex]

write a quadratic function in the given form whose graph satisfies the given condition.
passes through (-4, 0), (2, 0), & (6, -20) in intercept form.
pls dont just steal points away...i rly need help with this...can you provide work to if not thats ok
Answer:
[tex]\displaystyle y=-\frac{1}{2}(x+4)(x-2)[/tex]
Step-by-step explanation:
We want to find a quadratic that passes through the points:
[tex](-4, 0), \, (2, 0), \text{ and } (6, -20)[/tex]
In intercept form.
First, note that the first two given points are the x-intercepts of our quadratic. Intercept or factored form is given by:
[tex]y=a(x-p)(x-q)[/tex]
Where p and q are the x-intercepts, and a is the leading coefficient.
So, we will substitute -4 and 2 for p and q:
[tex]y=a(x-(-4))(x-(2))[/tex]
Simplify:
[tex]y=a(x+4)(x-2)[/tex]
Next, the third point (6, -20) tells us that y = -20 when x = 6. So:
[tex](-20)=a(6+4)(6-2)[/tex]
Solve for a:
[tex]-20=10(4)a\Rightarrow 40a=-20[/tex]
Thus:
[tex]\displaystyle a=\frac{-20}{40}=-\frac{1}{2}[/tex]
Hence, our equation in intercept from is:
[tex]\displaystyle y=-\frac{1}{2}(x+4)(x-2)[/tex]
Complete the table and graph the solutions of the the equation is y = 2x + 1

Insert three rational and three irrationall
no. between 150 and
and 0
160
Answer:
Step-by-step explanation:
Rational numbers:
(150+160)/2 = 310/2 = 155
(150+155)/2 = 305/2= 152.5
(155 +160)/2 = 315/2= 157.5
155, 152.5 , 157.5 are rational numbers between 150 and 160
Irrational numbers:
Irrational numbers are numbers that are non terminating and non repeating numbers
155.502003000.....
155.202002000......
156.3120578.......
Answer:
Required Answer :-1st rational number
= a + b/2
= 150 + 160/2
= 310/2 (1)
2nd rational number
Middle term of 150 and 160 is 155
= 150 + 155/2
= 305/2
3rd rational number
= 160 + 155/2
= 315/2

Each exterior angle of a regular decagon has a measure of (3x + 6)°. What is the value of x? x = 8 x = 10 x = 13 x = 18
Answer:
x = 10
Step-by-step explanation:
Each exterior angle of a regular decagon has a measure of (3x + 6)°. What is the value of x?
The sum of the exterior angles of a decagon = 360°
Decagon = 10 sides
Each angle in a decagon = 360/10
= 36°
We are told that:
Each exterior angle of a regular decagon has a measure of (3x + 6)°.
Hence,
(3x + 6)° = 36°
Collect like terms
3x = 36 - 6
3x = 30
x = 30/3
x = 10

1 What is the solution to the system of equations? (2 Points) x + y = 8 and - x + 3y = 4 O a. (-2, 10) O b. (10,-2) c. (3,5) O d. (53)
Answer:
(5 , 3)
Step-by-step explanation:
x + y = 8 ----------------(I)
-x + 3y = 4 ----------(II)
Add equation (I) and (II) and so x will be eliminated and we can find the value of y
(I) x + y = 8
(II) -x + 3y = 4
4y = 12 {Divide both sides by 4}
y = 12/4
y = 3
Plugin y = 3 inn equation (I)
x + 3 = 8 {Subtract 3 from both sides}
x = 8 -3
x = 5

Answer:
12,300
Step-by-step explanation:
I'll right this as a function to make it easier on me.
f(x) = 7500(1 + 0.8)^x
f(2) = 7500(1 + 0.8)^2
f(2) = 7500(1 + 0.64)
f(2) = 7500(1.64)
f(2) = 12300
Answer:
$8700
Step-by-step explanation:
0.08 x 2 yrs = 0.16
7500 x 0.16 =1200
7500 + 1200 = 8700
How many negative numbers are in the expression in part H? What will the sign of the solution be? How do you know
Answer:
When you have two negative signs, one turns over, and they add together to make a positive. If you have a positive and a negative, there is one dash left over, and the answer is negative.
Step-by-step explanation:
Answer:
There is one negative number in the expression, so the solution will be negative. There isn't a -1 in the denominator to cancel out the -1 in the numerator.

Which equation describes a line that passes through the point (-6, 2) and is parallel to
the line represented by 2y - 4x = 10?
Anyone know??
Answer:
y = 2x +14
Step-by-step explanation:
2y - 4x = 10
=> 2y = 4x + 10
=> y = 2x + 5
↑ the slope of this equation
parallel lines have the same slope, thus, the equation in the 4 options must have the same slope: 2.
plug in point (-6, 2) & the slope "2" into the equation: y = ax + b to find "b."
=> 2 = -6(2) + b
=> b = 14
plug in the slope "2" and the y-intercept(or b) "14" into the equation: y = ax + b
=> y = 2x +14

Line BC is tangent to the circle centered at A. Find the measure of angle BCA. Explain or show your reasoning.
Answer:
[tex] m\angle BCA= 33\degree[/tex]
Step-by-step explanation:
[tex] In\: \odot A[/tex] BC is tangent to the circle at point B.
Therefore, by tangent-radius theorem:
[tex] \therefore AB\perp BC[/tex]
[tex] \therefore \angle ABC = 90\degree [/tex]
[tex] In\: \triangle ABC, [/tex]
[tex] m\angle ABC +m\angle BAC +m\angle BCA= 180\degree [/tex]
[tex] 90\degree+57\degree +m\angle BCA= 180\degree [/tex]
[tex] 147\degree +m\angle BCA= 180\degree [/tex]
[tex] m\angle BCA= 180\degree - 147\degree[/tex]
[tex] m\angle BCA= 33\degree[/tex]
