I need help with these questions(see image).
Please show workings.
Answer:
see explanation
Step-by-step explanation:
(a)
The angle around the centre O of the circle = 360°, then
∠ AOB = 360° - 260° = 100°
Δ AOB is isosceles ( the radii OA and OB are congruent )
The altitude from O bisects ∠ AOB , thus
y = 50°
Since the triangle is isosceles the 2 base angles are congruent, so
x = [tex]\frac{180-100}{2}[/tex] = [tex]\frac{80}{2}[/tex] = 40°
(b)
∠ POR = 360° - 254° = 106°
Δ POR is isosceles (the radii OP and OR are congruent ) , then
the 2 base angles are congruent , thus
a = [tex]\frac{180-106}{2}[/tex] = [tex]\frac{74}{2}[/tex] = 37°

30 Points! A soccer ball hit from the ground into the air and is modeled by the function
h(t)=-16t^2+48t+2 (see attachment)
Answer:
A)
At t = 3/2
B)
36 feet
Step-by-step explanation:
The soccer ball is modeled by the function:
[tex]h(t)=-16t^2+48t[/tex]
Where h(t) represents the height in feet of the ball over time t.
Note that this is a quadratic equation.
Part A)
Since this is a quadratic, the maximum height will be reached when the ball reaches its vertex.
So, we will find the x-coordinate of the vertex.
The vertex is given by:
[tex]\displaystyle \Big (-\frac{b}{2a} , h( -\frac{b}{2a} ) \Big)[/tex]
In this case, a = -16 and b = 48. Thus, the t-coordinate is:
[tex]\displaystyle t=-\frac{48}{2(-16)}=-\frac{48}{-32}=\frac{3}{2}[/tex]
The ball will reach is maximum height at t = 3/2.
Part B)
To find the maximum height, we can simply substitute the value back into the function and evaluated. Therefore:
[tex]\displaystyle\begin{aligned} h(\frac{3}{2})&=-16\Big(\frac{3}{2}\Big)^2+48\Big(\frac{3}{2}\Big)\\\\ &=-16\Big(\frac{9}{4}\Big)+24(3)\\ \\ &=-36+72\\\\ &= 36 \end{aligned}[/tex]
The maximum height of the ball is 36 feet.
Write this percentage as a fraction in its simplest form.

6x + 3y = -12
-6x - 2y = 4
Answer:
x=2
y=-8
Step-by-step explanation:
6x+3y=-12
-6x-2y=4
3y=-12-6x
y=(-12-6x)/3
y=-4-2x
substitute y
-6x-2(-4-2x)=4
-6x+8+4x=4
-2x=-4
x=2
6(2)+3y=-12
12+3y=-12
3y=-24
y=-8
check:
6(2)+3(-8)=-12
12-24=-12
-6(2)-2(-8)=4
-12=16=4
2a=14 how do you solve this equation?

step two: divide 14 by 2
14/2 is 7 so a is equal to 7
Barry buys 200 pieces of stationery for £76.
Of the 200 pieces of stationery, x of them are rulers that cost 50p each and y of
them are pens that cost 20p each.
Find how many rulers Barry buys and how many pens he buys.
First, we take the first given information: 200 pieces = £76. Since the other unknowns are expressed in pence "p", we convert this amount to "p" = 76 x 100 = 7600p.
The information on "x" and "y" gives us 2 equations:
first:
x pieces + y pieces = 200 pieces (or x + y = 200)
placing "x" in terms of "y" gives us x = 200 - y
in terms of "y": y = 200 - x
50p(x) + 20p(y) = 7600p (or 50x + 20y = 7600)
solving for "x" gives:
x = (7600 - 20y) / 50
substituting y from our first equation gives:
x = (7600 - 20(200 - x)) / 50
x = (7600 - 4000 + 20x) / 50 (distribute - remember to distribute the negative sign)
x = (3600 + 20x) / 50 (simplify)
x = 360/5 + (2/5)x (subtract (2/5)x from both sides)
(3/5)x = 360/5
3x = 360
x = 120 (rulers bought)
substituting into our first equation:
y = 80 (pens bought)
check our solution using the second equation:
50x + 20y = 7600
50(120) + 20(80) = 7600
6000 + 1600 = 7600 (correct)
therefore:
x = 120 rulers Barry bought
y = 80 pens Barry bought
The number of rulers is 120 and the number of pens are 80 in number, bought by Barry.
What is an arithmetic operation?The four fundamental operations of arithmetic are addition, subtract, multiply, and division of two or more numbers. Included in them is the study of integers, especially the order of operations, which is important for all other aspects of mathematics, notably algebra, information management, and geometry.
x + y = 200 pieces
x = 200 - y (i)
y = 200 - x (ii)
50(x) + 20(y) = 7600p
Solve the equation for x,
x = (7600 - 20y) / 50
Substitute y from the equation,
x = (7600 - 20 (200 - x)) / 50
x = (7600 - 4000 + 20x) / 50
x = (3600 + 20x) / 50
x = 360/5 + (2/5)x
(3/5)x = 360/5
3x = 360
x = 120 is the number of scales.
Substitute the value of x in the first equation,
y = 80 is the number of pens.

I’m a 6th grader that needs help
Answer:
61 miles
Step-by-step explanation:
1 / 6 = 1/6
1/6 * 366 = 61
1/6 of 366 is 61
We can check our answer by multiplying 61 and 6 since we divided 366 and 6
61 * 6 = 366
Now that we have checked our answer, we can comfirm that 366 divided by 6 is 61 therefore, our answer is 61 miles in 1 hour

Find the derivative of f(x) = negative 8 divided by x at x = 11.
Answer: I think it’s
f ` (x) = - 8 / x²
f ` (11) = - 8 / 121
The value of the derivative at x = 11 is 8/121
The equation of the function is given as:
[tex]f(x) = -\frac 8x[/tex]
Rewrite the above equation as:
[tex]f(x) = -8x^{-1}[/tex]
Using the first principle, the derivative of f(x) is:
[tex]f'(x) = -1 \times -8x^{-1-1}[/tex]
[tex]f'(x) = -1 \times -8x^{-2}[/tex]
Evaluate the product
[tex]f'(x) = 8x^{-2}[/tex]
Rewrite the above equation as:
[tex]f'(x) = \frac{8}{x^2}[/tex]
Substitute 11 for x
[tex]f'(11) = \frac{8}{11^2}[/tex]
[tex]f'(11) = \frac{8}{121}[/tex]
Hence, the value of the derivative at x = 11 is 8/121
