Step-by-step explanation:
I hope this helps
Good luck ;)
The difference between the intercepted arc is 180°
What is an angle?An angle is formed from the intersection of two or more lines. Angles less than 90 degrees are called acute angles, angles greater than 90° are called obtuse angles while angles with a measure of 90° are called right angles.
Circle theorem states that if a tangent and a sectant, two tangent or two sectant meets outside a circle, the measure of the angle formed is half the difference between the intercepted arcs.
A secant and a tangent meet at a 90° angle outside the circle. Hence:
90° = (1/2) * difference between the intercepted arc
Difference between the intercepted arc = 180°
The difference between the intercepted arc is 180°

Can anyone tell me what this graph is in slope intercept form?
Answer:
the standard form equation is 1/2x^2-x-3/2=0
the vertex form equation is 1/2(x-1)^2-2=0
Step-by-step explanation:
Unfortunately, this can't be written in slope intercept form but I can write it in standard form(ax^2+bx+c) or vertex form (a(x-h)+k)
The vertex is (1,-2)
I estimate a=1/2 because the graph was widened and that can only be done by a fraction.
So, 1/2(x-1)^2-2=0
To find it in standard form
foil (x-1)(x-1)= x^2-2x+1
Then multiply by 1/2(x^2-2x+1)= 1/2x^2-x+1/2-2
To add 1/2-2. You mulitply -2 by 2/2 which equals 1/2-4/2 which equals -3/2
So the standard form equation is 1/2x^2-x-3/2=0

Answer:
The 17th term number of the arithmetic sequence will be: -97
i.e.
[tex]a_{17}=-97[/tex]Step-by-step explanation:
Given the arithmetic sequence
[tex]a_n=-6n+5[/tex]
Put [tex]n=17[/tex] in the arithemetic sequence to get the 17th term number
[tex]a_{17}=-6\left(17\right)+5[/tex]
[tex]a_{17}=-6\cdot \:17+5[/tex]
[tex]a_{17}=-102+5[/tex]
[tex]a_{17}=-97[/tex]
Therefore, the 17th term number of the arithmetic sequence will be: -97

7xy + 2x^2t
Step by step explanation:
You just group the like terms and simplify (pay attention to the signs)
5xy + 2xy = 7xy
-1x^2t + 3x^2t = 2x^2t
So the answer is : 7xy + 2x^2t

Answer:
x = 19 degrees
y = 84 degrees
Step-by-step explanation:
recall that for an isosceles triangle (which is pictured), the base angles have the same value.
In our case, we can see that the base angles are 48 deg and (3x-9) deg
if they are equal, we can equate them like this:
48 = 3x-9 (add 9 to each side)
48 + 9 = 3x
57 = 3x (divide both sides by 3)
x = 57/3
x = 19 degrees (answer)
also recall that the sum of the interior angles of a triangle add up to 180 deg, hence
48 deg + 48 deg + y deg = 180 deg
2(48) + y = 180
96 + y = 180
y = 180 - 96
y = 84 deg
2. What are the slope and y-intercept of the
line described by y = 3x - 6?
Answer:
If your trying to find the slope and y-int of that equation:
Slope: 3
y-int: (0, -6)
Identify the equation in point-slope form for the perpendicular bisector of the segment with endpoints J(−24,−4) and K(−4,6).
Option A:
y + 6 = 2(x − 4)
Option B:
y − 6 = 2(x + 4)
Option C:
y + 1 = −2(x − 14)
Option D:
y − 1 = −2(x + 14)
Given:
Endpoints of a segment are J(−24,−4) and K(−4,6).
To find:
The equation in point-slope form for the perpendicular bisector of JK.
Solution:
Slope of JK is
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\dfrac{6-(-4)}{-4-(-24)}[/tex]
[tex]m=\dfrac{6+4}{-4+24}[/tex]
[tex]m=\dfrac{10}{20}[/tex]
[tex]m=\dfrac{1}{2}[/tex]
Product of slopes of two perpendicular lines is -1. So, product of perpendicular line of JK is -2.
Perpendicular bisector of JK passes through the midpoint of JK.
[tex]Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]
[tex]Midpoint=\left(\dfrac{-24-4}{2},\dfrac{-4+6}{2}\right)[/tex]
[tex]Midpoint=\left(\dfrac{-28}{2},\dfrac{2}{2}\right)[/tex]
[tex]Midpoint=\left(-14,1\right)[/tex]
Point slope form:
[tex]y-y_1=m(x-x_1)[/tex]
where, m is slope.
Perpendicular bisector of JK passes through (-14,1) with slope -2. So, the point slope form of JK is
[tex]y-1=-2(x-(-14))[/tex]
[tex]y-1=-2(x+14)[/tex]
Therefore, the correct option is D.

Graph f(x)=3/2x+2. plz help
Answer:
draw a line trough (2,3) and (0, 2)
Step-by-step explanation:
f(x)=(3/2)x+2
so 3/2 is your slope and 2 is your y coordinate of y-intercept
pick any point to start for example (0, 0) and go slope=rise/run=3/2 and you will end-up at (2,3)
now you have a point (2,3) and a second the y-intercept (0,2)
draw a line trough those points
The length of a rectangular park is 20 feet longer than the width of the park. If the length of the park is 36 feet, what is the width of the park?
A.
4 feet
B.
16 feet
C.
42 feet
D.
56 feet
Answer: B. 16 feet
Step-by-step explanation:
We know that the length is 20 feet longer that the width. If the length of the park is 36 feet, the width is 20 feet less.
36 - 20 = 16 feet
So, the width of the park is 16 feet.

Find the supplementary angle of an angle measuring 183. If the supplementary angle does not exist, explain why. (1 point)
The supplementary angle is 177,
The given angle does not have a supplementary angle because supplementary angles add to the sum of 360'. The supplementary angle would need
to be 177 , and the supplement for it cannot be greater than 90° based on the definition of supplementary angles.
The supplementary angle is 107
The given angle does not have a supplementary angle because supplementary angles add to the sum of 180°. The supplementary angle would then
need to be -3, and negative angles are not allowed based on the definition of supplementary angles.
Answer:
"The given angle does not have a supplementary angle because supplementary angles add to the sum of 180°. The supplementary angle would then need to be -3, and negative angles are not allowed based on the definition of supplementary angles."
Step-by-step explanation:
A supplementary angle completes an angle less than 180 degrees by filling in what's left. Ex. 170 and 10 are supplementary angles because they add up to a straight line, 180.
Since 183 is greater than 180, no angle (a negative angle isn't an angle) can complete it.

if f(x) = 2(x – 3) + 4, findf (-8).
Answer:
f(-8) = -18
Step-by-step explanation:
given :
f(x) = 2(x – 3) + 4
to find f(-8), simply substitute x= -8 into the function:
f(x) = 2(x – 3) + 4
f(-8) = 2[(-8) – 3] + 4
= 2[-8 – 3] + 4
= 2[-11] + 4
= -22+4
= -18

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+163x+148
Answer:
x=5.09 seconds (times at max)
Step-by-step explanation:
The time at which the height of the rocket is maximum is 5.09 seconds and the maximum height is 563.14 feet.
What is a quadratic equation?It is a polynomial that is equal to zero. Polynomial of variable power 2, 1, and 0 terms are there. Any equation having one term in which the power of the variable is a maximum of 2 then it is called a quadratic equation.
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.
The quadratic equation is given below.
[tex]\rm y=-16x^2+163x+148[/tex]
Differentiate the equation with respect to x, then we have
[tex]\rm y' = \dfrac{dy}{dx}=\dfrac{d}{dx}(-16x^2+163x+148)\\\\y' =-32x + 163[/tex]
For y' = 0, then we have
32x = 163
x = 5.09
Then the maximum value of the rocket will be
[tex]\rm y=-16(5.09)^2+163(5.09)+148\\\\y = - 414.53 + 829.67 + 148\\\\y = 563.14\ ft[/tex]

You bought your friend's bike and owe $60.00 to your friend to finish paying for it. You do chores and earn $4.00 per day (7 days per week). If you give your friend all your money how much money would you have after 3 weeks of working?
Answer:
$24.
Step-by-step explanation:
I multiplied 4 by 7 to get 28. Then I multiplied $28 by three weeks and got $84. Since $84 is more than I owe I subtracted $84 by $60 and got $24. I would give my friend $60 and keep $24. Hope this helps! Have a great day!

Answer:
The coordinates of triangle A"B"C" will become
A( 5,-3 ) B( 9,6 ) C( -12 ,-4 )
Step-by-step explanation:
Original vertices of triangle ABC are ;
