Determine the length of a chord whose central angle is 65° in a circle with a radius of 9 feet.
Question 5 options:
1)
4.84 feet
2)
9 feet
3)
9.67 feet
4)
8.16 feet
Answer:
3)
9.67 feet
Step-by-step explanation:
The length of the chord is approximately 8.16 feet. The correct option is 4.
What is the length of the chord of the circle?A line segment connecting two points on a circle is referred to as a circle's chord in geometry. The circle's center is traversed by the longest segment that can be drawn between any two points on the circle.
To get the chord's length, we can utilize the formula for a circle's chord length. The equation is:
Length of chord = 2r sin(θ/2)
where r is the circle's radius, is its radian central angle, and sin is the sine function.
First, we need to convert the central angle from degrees to radians:
θ = 65° = (65/180)π = 1.14 radians
Now we can plug in the values:
Length of chord = 2(9 feet) sin(1.14/2) ≈ 8.16 feet
Therefore, the length of the chord is approximately 8.16 feet.

you are building a raft out of two by fours. How many two by fours do you need in your raft in order for you to float
Answer: 10 pieces of two by four woods.
Step-by-step explanation:
The number of woods that would be needed depends on the type of design chosen. A more complex design would require more wood to achieve it so it can satisfy the law of buoyancy and float on the water.
10 pieces of two by four would would be enough to build a raft that would float on water.

How can a number line help in ordering rational numbers:
How are number lines and the coordinate plane related:
Does the order of the numbers in an ordered pair matter when naming a point? Can that point be represented by more than one ordered pair?
A point is reflected across the x-axis. The new point is located at (4.75, -2.25). Write the ordered pair that represents the original point. Explain.
A point is reflected across the x-axis. The new point is (5, -3.5). What is the distance between the two points? Explain.
Answer:
1: It places them in an order sequentially relative to each other.
2: Number lines show the location of a number relative to each other on a one dimensional plane, and a coordinate plane does the same on two axis, or a two dimensional plane.
3: The order of the numbers do matter because the first one is the x coordinate and the second is the y. We nee a point of reference so we aren't able to make it so a single point can be represented by multiple ordered pairs, and vice versa so we can accurately share the information without additional interpretation.
4: (4.75, 2.25) Because to move across the x axis is to move in a direction perpendicular to it, meaning only the y coordinate will change. To be mirrored, it has to be copied and the absolute value of y (from both the x and y axis) must be maintained, just moved into the quadrant above or below it.
5: It is 7 units because the original coordinate would be 3.5 (as explained previously), and to move all the way to -3.5 you would need to cover the first 3.5 units to get to y=0, and then another 3.5 units down to get to y=-3.5. This is a total of 7 units moved.

Given that f(x) = x²-1,
a) Find f(5)
b) Find f-'(x)
c) Find f-'(8)
Answer:
step by step as shown
Step-by-step explanation:
f(x) = x²-1
f(5) = 5² - 1 = 24
f⁻¹(x)
y = x²-1
x = y² - 1 swap x and y
y² = x+1 ... x+1 ≥ 0 x≥-1
y = √x+1
f⁻¹(x) = √x+1
f⁻¹(8) =√8+1 = √9 = 3

Factor using the trinomial
10.
X2 + 13x + 12
Answer:
Factoring the trinomial: [tex]x^2+13x+12[/tex] we get the factors [tex]\mathbf{(x+1)(x+12)}[/tex]
Step-by-step explanation:
We need to factor the trinomial: [tex]x^2+13x+12[/tex]
We can factor the trinomial by breaking the middle term i.e 13x
Such that adding or subtracting gets the both terms we get 13x and multiplying both terms we get 12x^2
We can break 13x as: 12x and x
Adding them we get 13x and multiplying them we get 12x^2
So,
[tex]x^2+13x+12\\=x^2+12x+x+12\\=x(x+12)+1(x+12)\\=(x+1)(x+12)[/tex]
So, Factoring the trinomial: [tex]x^2+13x+12[/tex] we get the factors [tex]\mathbf{(x+1)(x+12)}[/tex]

Elizabeth bought 0.75 pound of sliced turkey for $3.45 and 1.5 pounds of sliced ham for $6.60. How much more was the turkey per pound?
Answer:
$0.20
Step-by-step explanation:
To find the difference per pound, we need to find how much each item costs per pound first.
Sliced turkey:
0.75 pound --- $3.45
1 pound --- × $3.45 = $4.60
Sliced Ham:
1.5 pounds --- $6.60
1 pound --- × $6.60 = $4.40
Difference:
$4.60 - $4.40 = $0.20
Answer:
$0.20

Totally blanking on how medians work
===============================================
The three medians of this triangle are:
PFREQDThese segments go from one vertex to the midpoint of the opposite side.
The median we'll focus on is PF.
The point C is the centroid of the triangle. It's where the three medians intersect. It turns out that C divides PF such that CF is twice as long as PC
In other words,
CF = 2*PC
This means,
PF = PC+CF .... segment addition postulate
PF = PC+2*PC ... replace CF with 2*PC
PF = 3*PC .... combine like terms
So the median PF is three times the length of its portion PC
We're told that PF = 24
We can then find the following:
PF = 3*PC
24 = 3*PC
3*PC = 24
PC = 24/3
PC = 8
Then we double this to get the length of CF
CF = 2*PC
CF = 2*8
CF = 16
This is the same as FC because the order of the endpoints don't matter when it comes to naming a segment.
The final answer is 16.
If 2x +9= 23, then 3x =
Answer:
21
Step-by-step explanation:
First you have to solve for x in the equation 2x + 9 = 23. Cancel 9 on both sides. You cancel 9 by subtracting 9 on the left side and on the right side:
23 - 9 = 14.
Now, you have 2x = 14. To isolate the variable, divide by 2 to cancel out 2.
14 / 2 = 7.
This will give you x = 7. Now that you know what x equals, you can substitute x in 3x. This would make it 3(7), or in other words 3 x 7.
3 x 7 = 21.
This means that 3x would be equal to 21. Hope it helps!
Answer:
to solve typical question like this first u have to find (x)[tex]2x + 9 = 23 \\ x = \frac{23 - 9}{2 } \\ x = \frac{14}{2} = 7[/tex]
therefore x = 7 then substitute the answer u got for (x) to the 3(x)3x3×7 = 21Please help me answer this :)

Describe the triple constraint. What are the three components and what is the relationship between them
Answer:
The triple constraint represents the three constraints or inputs which control the project's capacity to produce.
The three components are Budget, time, and scope.
The relationship between them is an interdependent or triangular shape.
Step-by-step explanation:
The triple constraint represents the three constraints or inputs which control the project's capacity to produce. Budget, Scope and Time.
Budget - The budget describes the estimated cost of the project. Time: The time represents the deadline to complete the project.Scope: This is simply what needs to be provided.These 3 components are dependent to each other.
For example, if time is restricted then scope and budget will be affected. similarly.
The relationship between the three is that one of the two other components must decrease while one component increases for the project to succeed as expected.

Dan is getting balloons for his grandfather's birthday party. He wants each balloon string to be 9 feet long. At the party store, string is sold by the yard. If Dan wants to get 83 balloons, how many yards of string will he need?
Answer:
I would think its 249 because 9 divided 3= 3 because 3 feet is 1 yard and then you do 83x3 and then you get 249.

In an arithmetic sequence, a3=15 and a8=0. What is the value of a5?
Answer:
a3=15 , n=3
a8=0, n=8
a5 = ?
an = a1+ (n-1)d
a3 = a1 + (3-1) d
a3=a1+2d
and a8 = a1 + (8-1 )d
a8= a1+ 7d
15 = a1 + 2 d-------1
0= a1 +7 d----------2
substacting eq 2 from eq 1
15= - 5d
- 5d = 15
divide by - 5
d = -3
putting the value of d in eq 1
15 = a1 + 7 (-3)
15 = a1 -21
adding 21 on both sides
a1-21+21= 15+21
a1 = 36
a5 = ?, n=5, d= -3, a1=36
a5 = 36 + (5-1) (-3)
= 36+(4)(-3)
= 36-12
= 24
