If AABC is reflected across the y-axis, what are the coordinates of A'?
Answer:
(-4, -2)
Step-by-step explanation:
A is initially (-4, 2); when we reflect over the y-axis, we will change from (x, y) to (x, -y). This gives us (-4, -2).
The coordinates of A' are (-5,-3).
What are coordinates?A coordinate system in geometry is a system that uses one or more integers, or coordinates, to define the position of points or other geometric components on a manifold such as Euclidean space. The order of the coordinates matters and they are sometimes identified by their position in an ordered tuple, and other times by a letter, as in "the x-coordinate." In elementary mathematics, the coordinates are assumed to be real numbers, but they can also be complex numbers or members of a more abstract system, such as a commutative ring. The use of a coordinate system allows geometry issues to be transformed into numerical problems and vice versa; this is the foundation of analytic geometry.Solution -If AABC is reflected across the y-axis, the coordinates of A' are (-5,-3).
The reflected graph is given below.
Therefore, the coordinates of A' are (-5,-3).

10/y=2/9, find the solution of y. stat.
Answer:
y=45
Step-by-step explanation:
Let's solve your equation step-by-step.
10 y = 2 /9
Step 1: Cross-multiply.
10 y = 2 /9
(10)*(9)=2*y
90=2y
Step 2: Flip the equation.
2y=90
Step 3: Divide both sides by 2.
2y /2 = 90 /2
y=45
brainliest please?
Answer:
y = 45
Step-by-step explanation:
10/y=2/9
10 = y * 2/9
10 = 2/9y
10 * 9 = 2/9y * 9
90 = 2y
90/2 = 2y/2
y = 45

Solving Exponential and Logarithmic Equations: What are the potential solutions to the equation below? 2ln(x+3)= 0 X=-3 and X=-4 O x=-2 and x=-4 X= 2 and X=-3 O x=2 and X= 4
Answer:
x = -2.

the annual
The present population of
of a town is 66550. If the annual population growth
rate is 10% what was
the Population growth of town 3 years ago ?
Answer:
Population (t=-3)= 50,000
Step-by-step explanation:
Giving the following information:
Annual growth rate (g)= 10%
Number of periods (n)= 3 years
Present Value (PV)= 66,550 people
To calculate the population three years ago, we need to use the following formula:
Population (t=-3)= PV / (1 + g)^n
Population (t=-3)= 66,550 / (1.1^3)
Population (t=-3)= 50,000

Write a quadratic equation given the x intercepts and other other point. Put steps together. Find the factors. Solve for a by substituting in the extra point. Write the equation in factored form.
Answer:
This question is clearly incomplete, so i will answer it in a really general way.
Suppose that for a quadratic function, we know that the x-intercepts are a and b.
And we also know that this function passes through the point (c, d).
First a definition, for a n-degree polynomial with the x-intercepts {x₁, x₂, ...,xₙ} and a leading coefficient K, we can write this polynomial in the factorized form as:
p(x) = K*(x - x₁)*(x - x₂)*...*(x - xₙ)
Now let's do the same for our quadratic function, we can write it as:
f(x) = K*(x - a)*(x - b)
(where a and b are known numbers)
Now we also know that this function passes through the point (c, d)
This means that:
f(c) = d
then:
d = K*(c - a)*(c - b)
With this equation we can find the value of K,
K = d/( (c-a)*(c - b))
Then the quadratic function is:
[tex]f(x) = d\frac{(x-a)}{(c-a)} \frac{(x-b)}{(c-b)}[/tex]
Where again, it is supposed that you know the values of a and b, and also the point (c, d)

What is the area of kite ABCD?
sq yd
Answer:
51.5?
Step-by-step explanation:
I think it's just length times width divided by 2
The area of the kite ABCD is 51.56 square yards.
What is the area of the kite?A kite's area is the amount of space enclosed or surrounded by a kite in a two-dimensional plane.
A kite's area equals half the product of its diagonal lengths. The formula for calculating a kite's area is:
Area = 1/2 × d₁ × d₂
Where d₁ and d₂ are long and short diagonals of a kite.
Here, AC = 12.5 yards and BD = 8.25 yards
Substitute the values of d₁ = 12.5 yards and d₂ in the formula of the kite's area:
The area of the kite = 1/2 × 12.5 × 8.25
The area of the kite = 51.5625
The area of the kite ≈ 51.56 square yards
Thus, the area of the kite ABCD is 51.56 square yards.

given:quadrillateral ABCD inscribed in a circle
prove angel A and angel C are supplementary angel B and D are supplementary
Answer:
Step-by-step explanation:
Given: quadrilateral ABCD inscribed in a circle
To Prove:
1. ∠A and ∠C are supplementary.
2. ∠B and ∠D are supplementary.
Construction : Join AC and BD.
Proof: As, angle in same segment of circle are equal.Considering AB, BC, CD and DA as Segments, which are inside the circle,
∠1=∠2-----(1)
∠3=∠4-----(2)
∠5=∠6-------(3)
∠7=∠8------(4)
Also, sum of angles of quadrilateral is 360°.
⇒∠A+∠B+∠C+∠D=360°
→→∠1+∠2+∠3+∠4+∠5+∠6+∠7+∠8=360°→→→using 1,2,3,and 4
→→→2∠1+2∠4+2∠6+2∠8=360°
→→→→2( ∠1 +∠6) +2(∠4+∠8)=360°⇒Dividing both sides by 2,
→→→∠B + ∠D=180°as, ∠1 +∠6=∠B , ∠4+∠8=∠B------(A)
As, ∠A+∠B+∠C+∠D=360°
∠A+∠C+180°=360°
∠A+∠C=360°-180°------Using A
∠A+∠C=180°
Hence proved.
