How do you find the area of a circular park and the radius is 18 yards
Answer:
The area of the circular park is about 1017.88
Step-by-step explanation:
First, we recall the area of a circle.
A= πr^2
Next, we plug in the radius
A= π*18^2
A= π*324
A= 1017.88
To conclude, that is how you find the area of a circular park.

∠1 and ∠2 are supplementary. ∠1=3x°∠2=(2x−25)° What is the value of x? Select from the drop down menu to correctly answer the question. X = Choose.
Answer:
x=41
Step-by-step explanation:
supplementary angles add to 180
3x + (2x-25) = 180
5x = 205
x= 41
angle1 3x41 = 123
angle 2 (2x41) -25 = 57
123 +57 = 180

Answer:
x = 1 +√5
Step-by-step explanation:
There are different formulas for the area of a triangle available, depending on the given information.
FormulasWhen two sides and the angle between them are given, the relevant area formula is ...
Area = 1/2(ab)sin(C)
When the base and height of a triangle are given, the relevant area formula is ...
Area = 1/2bh
Equal AreasThe problem statement tells us the two triangles shown have equal areas. That means the two formulas will give the same result.
Area from angle = Area from base/height
1/2(x·x)sin(30°) = 1/2(x-2)(x+1)
x² = 2(x² -x -2) . . . . . . . . . . . use sin(30°) = 1/2, multiply by 4
x² -2x -4 = 0 . . . . . . . . subtract x², eliminate parentheses
(x -1)² = 5 . . . . . . . . . add 4+1 to complete the square
Value of xx = 1 ± √5 . . . . . . take the square root, add 1
The value of x must be greater than 2 in order for the triangle side lengths to be positive. (x-2 > 0) This means x = 1-√5 is an extraneous solution.
The value of x is 1 +√5.
what are the x-intercepts of 2x+10
Answer:
-5
Step-by-step explanation:
x-intercepts occur when y = 0
⇒ 2x + 10 = 0
⇒ 2x = -10
⇒ x = -5
So the x intercept of 2x + 10 is (-5, 0)
Answer:
-5
Step-by-step explanation:
To find the x intercepts we must replace y with 0 and solve for X
So our equation is 0=2x+10
Now we must get x by itself by subtracting 10 on both sides. We subtract 10 because it is being added.
We are left with -10=2xSo now we ask ourselves, what times 2 will give us -10Well, instead of guessing we can solve :)
Divide 2 on both sides, this cancels out the two on the right and makes the -10 on the left turn into a -5.
Now we are left with x=-5
Thus, our answer is -5
Hope this helps!

Equilateral triangle
scalene triangle
Isosceles
======================================================
Explanation:
Use the distance formula to calculate the distance from R to S. This is identical to the length of segment RS.
[tex]R = (x_1,y_1) = (-3,-1) \text{ and } S = (x_2, y_2) = (0,3)\\\\d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(-3-0)^2 + (-1-3)^2}\\\\d = \sqrt{(-3)^2 + (-4)^2}\\\\d = \sqrt{9 + 16}\\\\d = \sqrt{25}\\\\d = 5\\\\[/tex]
Segment RS is exactly 5 units long.
-----------------------
Repeat similar steps to find the length of segment ST
[tex]S = (x_1,y_1) = (0,3) \text{ and } T = (x_2, y_2) = (3,0)\\\\d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(0-3)^2 + (3-0)^2}\\\\d = \sqrt{(-3)^2 + (3)^2}\\\\d = \sqrt{9 + 9}\\\\d = \sqrt{18}\\\\d \approx 4.2426\\\\[/tex]
ST is roughly 4.2426 units long.
------------------------
Lastly, let's calculate the length of segment TR.
[tex]T = (x_1,y_1) = (3,0) \text{ and } R = (x_2, y_2) = (-3,-1)\\\\d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(3-(-3))^2 + (0-(-1))^2}\\\\d = \sqrt{(3+3)^2 + (0+1)^2}\\\\d = \sqrt{(6)^2 + (1)^2}\\\\d = \sqrt{36 + 1}\\\\d = \sqrt{37}\\\\d \approx 6.0828\\\\[/tex]
TR is about 6.0828 units long.
------------------------
Summary of the segment lengths:
RS = 5 exactlyST = 4.2426 approximatelyTR = 6.0828 approximatelyThe three sides are different lengths.
Therefore, the triangle is scalene.

The half-life of a radioactive element is five years. A scientist has 18 grams of the element. The equation
representing the number of grams, g, after x years is §. What is the annual rate of decay?
g=18(0.5)
The annual rate of decay is r = 0.87
How to use the half-life?
We know that if a quantity has a half-life of T, then the rate of decay must be such that:
r^T = 0.5
This means that when a time T passes, the original quantity becomes half of what it originally was.
In this case we know that the half-life is T = 5 years, then we have:
r^5 = 0.5
r = 0.5^(1/5) = 0.87
Then the annual rate of decay is r = 0.87, and if the initial quantity is 18 grams, we can write the exponential decay as:
f(t) = 18g*(0.87)^t

Problem 3: Two rectangular gardens are made from 200 yards of fencing. The
gardens are planted beside each other so they share a common fence. If the
farmer wants the total area of the gardens to be as large as possible, what
dimensions should be used to make the gardens, and what will the largest area
possible be?
The area of a shape is the amount of space on the shape
The largest possible area of the garden is 1666.67 square yards
How to determine the maximum areaRepresent the length of the gardens with y, and the widths of the whole garden with x.
So, the perimeter of the garden is:
[tex]P = 3y + 2x[/tex]
The farmer has 200 yards.
So, we have:
[tex]3y + 2x= 200[/tex]
The area of the garden is:
[tex]Area = xy[/tex]
Divide the amount of fencing equally to maximize the area.
So, we have:
[tex]3y + 2x = 100 + 100[/tex]
This gives
[tex]3y = 100 \to y = \frac{100}3[/tex]
[tex]2x = 100 \to x = 50[/tex]
Recall that:
[tex]Area = xy[/tex]
So, we have:
[tex]Area = 50 * \frac{100}3[/tex]
Evaluate the product
[tex]Area = \frac{5000}3[/tex]
[tex]Area = 1666.67[/tex]
Hence, the largest possible area of the garden is 1666.67 square yards

Dion bought 3 pounds of oranges and 2 pounds of grapefruit. Write an expression to represent the amount of money Dion spent on the fruit. Then evaluate the expression. How much did Dion spend?
Solution:
Given:
Dion bought 3 pounds of oranges, and 2 pounds of grapefruit1 pound of oranges = o = $0.991 pound of grapefruit = g = $1.59Let's represent the number of oranges and grapefruits by the letters o and g.
This means that...
Dion purchase: 3o + 2gNow, let's solve the expression to find out how much does Dion has to pay.
Substituting o and g with the given values:
3o + 2g=> 3(0.99) + 2(1.59)=> 3(1.00 - 0.01) + 2(1.60 - 0.01)=> (3 - 0.03) + (3.20 - 0.02)=> 2.97 + 3.18=> $6.15We also know that Dion gave a $20. To find the change, subtract the money Dion gave with the money required to pay for the fruits.
=> 20 - 6.15=> $13.85Thus, Dion got $13.85 as change.

Chord AB is 3cm from the center of a circle, the radius of the circle is 5cm, calculate the length of the chord.
Answer:
[tex]\large{\boxed{\sf Chord = 8cm }}[/tex]
Step-by-step explanation:
First see figure in attachment . As we know that ,Perpendicular from centre of the circle bisects the chord . Hence here ,
OC is the perpendicular bisector of chord AB . Let us assume that AC = x , therefore ,[tex]\sf\qquad\longrightarrow AB = 2AC = 2x [/tex]
Now in ∆OAC , by Pythagoras Theorem , we have ;
[tex]\sf\qquad\longrightarrow (5cm)^2= x^2+(3cm)^2\\ [/tex]
[tex]\sf\qquad\longrightarrow 25cm^2=x^2+9cm^2\\[/tex]
[tex]\sf\qquad\longrightarrow x^2=25cm^2-9cm^2\\[/tex]
[tex]\sf\qquad\longrightarrow x^2=16cm^2\\ [/tex]
[tex]\sf\qquad\longrightarrow \pink{ x = 4cm } [/tex]
Therefore , the length of chord will be ,
[tex]\sf\qquad\longrightarrow AB = 2x \\ [/tex]
