To find the equation of the drone's path, we can first find the coordinates of the center of the circle that the drone is flying around. We can do this by finding the midpoint between the two points the drone passes over:
Midpoint in the x-direction: (220 ft - 180 ft)/2 = 20 ft to the right of the origin.
Midpoint in the y-direction: (230 ft - 180 ft)/2 = 25 ft above the origin.
Therefore, the center of the circle is located at (20, 25) ft.
The radius of the circle can be found by calculating the distance between the center of the circle and either of the two points the drone passes over:
Radius: sqrt((20-(-180))^2 + (25-180)^2) = sqrt(40000 + 15625) = 205 ft (rounded to the nearest whole number)
So the equation for the drone's path is:
(x - 20)^2 + (y - 25)^2 = 205^2
To find how far north of Megan's position the drone is when it passes due north, we can substitute x = 0 into the equation:
(0 - 20)^2 + (y - 25)^2 = 205^2
400 + (y - 25)^2 = 42025
(y - 25)^2 = 41625
y - 25 = +/-sqrt(41625)
y = 25 +/- 204.06
So the drone is either 229.06 ft north or 22.94 ft south of Megan's position when it passes due north. Rounded to three decimal places, the answer is 229.06 ft north.
In triangle PQR is equal to QR and angle R is equal to 50° then find the measure of Q
Answer:
Step-by-step explanation:
Since PQR is a triangle with QR = PQ, we have:
∠PQR = ∠QPR (since the angles opposite to equal sides are equal)
Let x be the measure of ∠QPR. Then:
∠PQR + ∠QPR + ∠R = 180° (sum of angles in a triangle)
x + x + 50° = 180°
2x = 130°
x = 65°
Therefore, the measure of ∠QPR is 65°.
What is the Value of X?
The value of x is found by using the similarity theorem to create a proportion of the sides of the similar triangle, such that: x = 6 cm.
How to Find the Value of x Using Similarity Theorem?Both triangles in the image above are similar to each other based on the AA similarity theorem, which states if two angles of one triangle are congruent to two angles of another triangle, then the triangles are similar. This means that the corresponding sides of the triangles are proportional.
Therefore, we will have:
x/42 = 4/28
Cross multiply:
28x = 168
x = 168/28

A magician makes potions by combining maple syrup from a magical maple tree with ordinary water. The magician starts with a large supply of two potions: a red potion, which is 60% magical syrup by volume (and the rest is just water), and a blue potion, which is 30% magical syrup by volume. (Perhaps you're wondering how the same syrup can produce both red and blue potions. That's why it's magic syrup!)
(a) Find the amount of red potion (in mL) that must be added to 500 mL of blue potion in order to produce a potion that is 40% magical syrup by volume.
(b) Find the amounts of red potion and blue potion (in mL) that can be combined in order to produce 100 mL of a potion that is 54% magical syrup by volume.
(c) Does there exist a combination of red potion and blue potion that can produce a potion that is 75% magical syrup by volume?
Taking the quantities by volume of each potion into consideration, we can respectively answer 250ml (A), 40 mL of red and 60 mL of blue potion (B), and no (C).
How to find the solutionFor question A: Let x be the amount of red potion (in mL) that must be added to 500 mL of blue potion to produce a potion that is 40% magical syrup by volume. The amount of magical syrup in the red potion is 0.6x, and the amount of magical syrup in the blue potion is 0.3(500) = 150. The total amount of syrup in the final mixture is 0.4(500 + x), and the amount of magical syrup in the final mixture is 0.4x + 150. We can set up the equation:
0.4x + 150 = 0.4(500 + x)
Solving for x, we get x = 250 mL. Therefore, 250 mL of red potion must be added to 500 mL of blue potion to produce a potion that is 40% magical syrup by volume.
For question B: Let x be the amount of red potion (in mL) and y be the amount of blue potion (in mL) that must be combined to produce 100 mL of a potion that is 54% magical syrup by volume. The amount of magical syrup in the red potion is 0.6x, and the amount of magical syrup in the blue potion is 0.3y. The total amount of syrup in the final mixture is x + y, and the amount of magical syrup in the final mixture is 0.6x + 0.3y. We can set up the equations:
x + y = 100 (equation 1)
0.6x + 0.3y = 0.54(100) (equation 2)
Solving for x and y, we get x = 40 mL and y = 60 mL. Therefore, 40 mL of red potion and 60 mL of blue potion must be combined to produce 100 mL of a potion that is 54% magical syrup by volume.
For question C: No, there does not exist a combination of red potion and blue potion that can produce a potion that is 75% magical syrup by volume. The amount of magical syrup in the red potion is 60%, which is more than twice the amount of magical syrup in the blue potion (30%). Therefore, any combination of the two potions will always have less than 60% magical syrup by volume.

3 x minus 4 y = 16. 2 x + 3 y = 5.
Answer:
It's 5
Step-by-step explanation:
i tootk the test
Step-by-step explanation:
To solve the system of equations:
3x - 4y = 16
2x + 3y = 5
We can use either substitution or elimination method. Here, we will use the elimination method:
Multiply the second equation by 4 to get:
8x + 12y = 20
Now we can add this equation to the first equation:
3x - 4y + 8x + 12y = 16 + 20
Simplifying the left side and adding the right side, we get:
11x = 36
Dividing both sides by 11, we get:
x = 36/11
Substituting this value of x into the second equation, we get:
2(36/11) + 3y = 5
Multiplying through by 11 to eliminate the fraction, we get:
72/11 + 3y = 55/11
Subtracting 72/11 from both sides, we get:
3y = -17/11
Dividing both sides by 3, we get:
y = -17/33
Therefore, the solution to the system of equations is:
x = 36/11, y = -17/33
or in decimal form,
x ≈ 3.27, y ≈ -0.52
3.) The line which is the graph of y = 2x -4 is transformed by the rule (x,y) (-x, -y). What is the

The slope of the image of the original line y = 2x - 4 after the transformation (x,y) (-x, -y) is -2.
What is slope intercept form of line?The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of the original line y = 2x - 4 is 2.
To find the slope of the image after the transformation, we can apply the transformation rule to two points on the original line, and then find the slope of the line passing through the images of those two points.
Let's choose two points on the original line:
Point 1: (0, -4)
Point 2: (1, -2)
Now we apply the transformation rule to each of these points:
Point 1 image: (-0, -(-4)) = (0, 4)
Point 2 image: (-1, -(-2)) = (1, 2)
The images of these two points lie on the line y = -2x + 4. The slope of this line is -2.
Therefore, the slope of the image of the original line y = 2x - 4 after the transformation (x,y) (-x, -y) is -2.

The area of a plane shape is given by A=(10x-2)cm square. The area is not greater or equal to 12cm square. It is however not less than 2cm. Find the smallest possible area of this shape
Answer:
Step-by-step explanation:
We know that the area of the plane shape is given by A = (10x - 2) cm^2, and we also know that:
A is not greater than or equal to 12 cm^2 (i.e., A < 12), and
A is not less than 2 cm^2 (i.e., A > 2).
To find the smallest possible area of the shape, we need to find the smallest possible value of x that satisfies these conditions.
From the given conditions, we have:
10x - 2 < 12
10x < 14
x < 1.4
and
10x - 2 > 2
10x > 4
x > 0.4
Therefore, the smallest possible value of x that satisfies both conditions is:
0.4 < x < 1.4
To find the smallest possible area, we can substitute the lower bound of x into the area formula:
A = (10x - 2) cm^2
A = (10 × 0.4 - 2) cm^2
A = 2 cm^2
Therefore, the smallest possible area of the shape is 2 cm^2.

Ryan wishes to purchase a new boat and can afford monthly payments of up to $500 per month. Finance is available, and the terms are that the loan lasts for 10 years and the annual interest rate is 13%. What is the maximum price for a boat that Ryan's budget can afford? Round your answer to the nearest hundred dollars.
Answer:
First, we need to calculate the total number of payments Ryan will make over 10 years, which is 10 years x 12 months/year = 120 months.
Next, we can use the formula for the present value of an annuity to calculate the maximum price of the boat:
PV = PMT x [1 - (1 + r/n)^(-nt)] / (r/n)
where PV is the present value, PMT is the monthly payment, r is the annual interest rate, n is the number of compounding periods per year, and t is the number of years.
Plugging in the values we have:
PMT = $500
r = 0.13
n = 12 (since the loan is monthly)
t = 10
PV = $500 x [1 - (1 + 0.13/12)^(-12x10)] / (0.13/12)
PV = $44,484.72
Therefore, the maximum price for a boat that Ryan's budget can afford, rounded to the nearest hundred dollars, is $44,500.

Dirk and Steve both plan to run to a spot on the school board in their city. They must each collect a certain number of signatures to get their name on the ballot. So far, Dirk has 20 signatures, but Steve just started and doesn't have any yet. Kirk is collecting signatures at an average rate of 6 per hour, while Steve can get 10 signatures every hour. Assuming that their rate of collection stays the same, eventually the two will have collected the same number of signatures. How many hours will have gone by?
Answer: 2.5 hours
Step-by-step explanation:
Let's call the number of signatures that Steve needs to collect "x". We know that Dirk has 20 signatures, so he needs to collect "x - 20" more signatures to have the same number as Steve.
We can set up an equation to represent this:
6h + 20 = 10h + x - 20
Simplifying this equation, we get:
x = 4h + 40
So, Steve needs to collect 4 signatures more per hour than Dirk to eventually collect the same number of signatures. We can solve for "h", the number of hours it will take for them to have the same number of signatures:
6h + 20 = 10h + (4h + 40)
6h + 20 = 14h + 40
8h = 20
h = 2.5
So, it will take 2.5 hours for Dirk and Steve to have collected the same number of signatures.
willka can cover 13.5 m^2 with 3L of paint
Willka would need 6 liters of paint to cover an area of 27 square meters according to the ratio.
What is ratio?A ratio is a comparison of two or more values or quantities. It is a way of expressing the relationship between two or more quantities in a mathematical form. A ratio is typically expressed in the form of "a:b" or "a to b", where a and b are two values being compared.
According to question:
To find the coverage per liter of paint, we can divide the total area covered by the amount of paint used.
In this case, we can divide 13.5 m² by 3 L:
Coverage per liter = 13.5 m² / 3 L = 4.5 m²/L
This means that with 1 liter of paint, Willka can cover an area of 4.5 square meters.
If we know the area to be painted, we can use this ratio to determine how much paint is needed.
For example, if we want to paint an area of 27 square meters, we can calculate:
Paint needed = area to be painted / coverage per liter = 27 m² / 4.5 m²/L = 6 L
So Willka would need 6 liters of paint to cover an area of 27 square meters.
