The length of the arc will be 10.5 ft. The arc length is the measurement of how long an arc is.
What is an arc?An arc is a smooth curve that links two locations. The arc length is the measurement of how long an arc is.
A graph arc is an ordered pair of neighboring vertices in a graph. An arc, in particular, is any piece of a circle's circumference.
The given data in the problem is;
r is the radius= 2 ft
s is the arc length=?
[tex]\rm \theta[/tex] is the angle in radian= [tex]\frac{5 \pi}{3}[/tex]
The arc of the circle is given by;
[tex]\rm s = r\theta \\\\ \rm s = 2\times\frac{5 \pi}{3} \\\\ \rm s = \frac{10 \pi}{3} \\\\ \rm s = =10.5 \ ft[/tex]

Answer:
In explanation.
Step-by-step explanation:
what are you exactly looking for here are some of my ideas.
How many pounds did it drop=?
from 87 to 16 pounds it dropped a total of 71 pounds.
what was the percent increase=?
The percentage of the pound increase is 81.6092.
you calculate this bu - value 2 by value 1 the divided your answer with value 1 you then times that answer by 100.
Maybe the decimal form,written form,fraction form, of the awnser after you subtract.
decimal form is 0.71
written form is seventy one pounds.
fraction form=71/100 after subtract.
are any of these the things your looking for?

21) The graph of the function f(x) = x3 - 2x2 + 4x – 8 intersects the x-axis at the point (2,0) as shown.
Which statement is true?
A) The function has 3 different zeros.
B) The function has 1 real zero that occurs 1 time.
C) The function has 1 real zero that occurs 2 times.
D) The function has 1 real zero that occurs 3 times.
The true statement about the graph of the function f(x) = x3 - 2x2 + 4x – 8 is (B) The function has 1 real zero that occurs 1 time.
How to determine the true statementThe function of f(x) is represented as:
[tex]f(x)=x^3-2x^2+4x-8[/tex]
Differentiate the function f(x)
[tex]f'(x)=3x^2-4x+4[/tex]
Calculate the minimum value using:
[tex]x = -\frac b{2a}[/tex]
So, we have:
[tex]x = -\frac {-4}{2*3}[/tex]
[tex]x = \frac {2}{3}[/tex]
Substitute 2/3 in f'(x)
[tex]f'(2/3)=3*(2/3)^2-4(2/3)+4[/tex]
[tex]f'(2/3)=\frac 83[/tex]
The value of f'(2/3) is greater than 0.
This means that the function f(x) has 1 real zero, and it occurs once at point (2,0)
Hence, the true statement is (b)

4. SSS (Side to Side to Side Congruence rule)
Step-by-step explanation:
this is D reflexive property of SSS
3. Any geometric figure compared to itself is congruent to itself so this is why:
4. Since we have a parallelogram, therefore we can say:
Both triangles ABC and CDA satisfy the side to side to side congruence, since their 3 sides are congruent.
So, It's D.

Answer:
Distance between Gas Station and House = 7.81 miles.
Step-by-step explanation:
The distance between the two locations is 7.81 miles
Distance between two pointsGiven the point at (4,3) represents the location of her house, and the point at (10, 8) represents the location of the gas station.
The distance between the two locations will be determined using the formula
D [tex]=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Substitute the given coordinate into the formula
[tex]D=\sqrt{(-6)^2+(-5)^2}\\D=\sqrt{(4-10)^2+(3-8)^2}\\D=\sqrt{36+25}\\ D=\sqrt{61}\\ D=7.81miles[/tex]

Factor the polynomial completely using the X method. X2 11x 24 An x-method chart shows the product a c at the top of x and b at the bottom of x. Above the chart is the expression x squared 11 x 24. The value of ac is. The value of b is. The equivalent factored form of the polynomial is.

How to find the factors of a quadratic expression?If the given quadratic expression is of the form
[tex]ax^2 + bx + c[/tex]
then its factored form is obtained by two numbers alpha( α ) and beta( β) such that:
[tex]b = \alpha + \beta \\ ac =\alpha \times \beta[/tex]
Then writing b in terms of alpha and beta would help us getting common factors out.
For the considered polynomial, we've got the quadratic expression as:
[tex]x^2 + 11x + 24[/tex]
Comparing this with [tex]ax^2 + bx + c[/tex], we get:
a = 1 (since [tex]x^2 = 1\times x^2[/tex] )b = 11c= 24Therefore, we have : ac = c = 24
Two numbers whose multiplication gives 24 and and whose addition gives 11.
24 = [tex]2 \times 2 \times 2 \times 3[/tex]
If we take first three 2s, and 3, then:
[tex]24 = 8 \times 3 = (2 \times 2 \times 2) \times 3\\11 = 8 + 3 = (2 \times 2 \times 2) + 3[/tex]
Thus, we need to write 11 in the middle in terms of 8 and 3:
[tex]x^2 + 11x + 24 = x^2 + 8x + 3x + 24 = x(x+8) + 3(x+8) = (x+3)(x+8)[/tex]
Thus, the factored form of the considered polynomial is [tex](x+3)(x+8)[/tex]

The 2 above regular hexagons are similar. (see figures) The smaller hexagon was
increased by a factor of 5:7. What is the length of each side of the larger hexagon?
The smaller and the larger hexagons both have 6 sides
The length of each side of the larger hexagon
How to determine the length of each side of the larger hexagon
The given parameters are:
Smaller side, l = 10
Scale factor = 5 : 7
Represent the length of each side of the larger hexagon with L.
So, we have:
l : L = 5 : 7
Substitute 10 for l
10 : L = 5 : 7
Multiply the ratio by 2
10 : L = 5 *2 : 7 *2
Evaluate the product
10 : L = 10 : 14
By comparison, we have:
L = 14
Hence, the length of each side of the larger hexagon
