Answer:
[tex]\dfrac{155}{18} \pi \textrm{ cm}[/tex]
Step-by-step explanation:
This problem asks us to find the length of an arc ACB on the circumference of a circle with center O and a radius of 5 cm.
We first must solve for the total circumference (perimeter) of the circle. This is represented by the formula C = 2πr. Hence, the circumference of this circle is:
C = 2π(5) cm
C = 10π cm
Next, we have to find what fraction of 360º the major arc ACB is in order to deduce how much of the circle's total circumference the arc takes up.
[tex]\dfrac{(360 - 50)\textdegree}{360\textdegree} = \dfrac{31}{36}[/tex]
Finally, we can multiply the amount of circumference that arc ACB takes up by the length of the whole circumference to get the length of arc ACB.
[tex]\textrm{Length of arc } ABC = \dfrac{31}{36} \cdot 10\pi[/tex]
[tex]= \dfrac{310}{36} \pi[/tex]
[tex]= \dfrac{155}{18} \pi \textrm{ cm}[/tex]
Answer:
[tex]\textsf{Length of major arc $\overset{\frown}{ACB}$}: \;\; \boxed{\dfrac{155}{18}\pi\; \sf m}[/tex]
Step-by-step explanation:
[tex]\boxed{\begin{minipage}{6.4 cm}\underline{Arc length}\\\\Arc length $= \pi r\left(\dfrac{\theta}{180^{\circ}}\right)$\\\\where:\\ \phantom{ww}$\bullet$ $r$ is the radius. \\ \phantom{ww}$\bullet$ $\theta$ is the angle measured in degrees.\\\end{minipage}}[/tex]
Angles around a point sum to 360°. Therefore:
[tex]\begin{aligned}\implies m \angle BOA&=360^{\circ}-m \angle AOB\\&=360^{\circ}-50^{\circ}\\&=310^{\circ}\end{aligned}[/tex]
Therefore, the given values are:
r = 5 mθ = m∠BOA = 310°To find the length of the major arc ACB, substitute the given values into the arc length formula:
[tex]\begin{aligned}\implies \overset{\frown}{ACB}&=\pi \cdot 5 \cdot \left(\dfrac{310^{\circ}}{180^{\circ}}\right)\\\\&=5\pi \cdot \dfrac{31}{18}\\\\&=\dfrac{155}{18}\pi\; \sf m\end{aligned}[/tex]

If Jeremy needs 64 gallons of compost to plant his garden in the spring, how much brown material will he need? How much green material will he need?
The amount of Brown material: 39 gallons and Green material: 13 gallons.
What is a proportion?A proportion is a fraction of a total amount, and in problems involving it, basic arithmetic operations such as multiplication or division are used along with the unit rates to find the equivalent measures.
On the first column of the table, the total amount is:
12.75 + 4.25 = 17 gallons.
The fractions of each material are given as follows:
Brown material: 12.75/17 = 0.75
Green material: 4.25/17 = 0.22.
Therefore, the amount of brown material needed with 52 gallons is:
0.75 x 52 = 39 gallons.
The amount of green material needed with 52 gallons is:

write the equation for a cubic function that has been shifted up 2 units and left 10 units.
The polynomial f''(x) = 3 · (x + 10)³ + 2 · (x + 10)² - 4 · (x + 10) + 11 represents a cubic function equal to polynomial f''(x) = 3 · (x + 10)³ + 2 · (x + 10)² - 4 · (x + 10) + 11 shifted up two units and left ten units.
How cubic functions are modified by means of translations
Cubic equations are polynomials of grade 3, whose form is shown below:
y = a · x³ + b · x² + c · x + d
Where:
x - Independent variable.y - Dependent variable. a, b, c, d - Real coefficients.In this problem we need to apply horizontal and vertical translations to modify a given cubic polynomial:
Horizontal translation
f(x) → f(x - k)
Where k > 0 for a rightward translation.
Vertical translation
f(x) → f(x) + k
Where k > 0 for a upward translation.
First, assume a given cubic function:
(a, b, c, d) = (3, 2, - 4, 9)
f(x) = 3 · x³ + 2 · x² - 4 · x + 9
Second, apply a vertical translation two units up: (k₁ = 2)
f'(x) = 3 · x³ + 2 · x² - 4 · x + 9 + 2
f'(x) = 3 · x³ + 2 · x² - 4 · x + 11
Third, apply a horizontal translation ten units left:

A square is a two-dimensional plane figure with four equal sides and all four angles are equal to 90 degrees. The properties of the rectangle are somewhat similar to a square, but the difference between the two is, a rectangle has only its opposite sides equal. Therefore, a rectangle is called a square only if all its four sides are of equal length.
The most important properties of a square are listed below:
All four interior angles are equal to 90°.All four sides of the square are congruent or equal to each other.The opposite sides of the square are parallel to each other.The diagonals of the square bisect each other at 90°.The two diagonals of the square are equal to each other.The square has 4 vertices and 4 sides.The diagonal of the square divides into two similar isosceles triangles.The length of diagonals is greater than the sides of the square.Area of square=(side)²

2)
is the difference from 1.0 if the test-statistic is negative.
3)
is correct if the test-statistic is zero.
4)
is correct if the test-statistic is positive.
For a lower-tail test, a t-statistic that is negative and far from zero would then lead us to favor the alternative hypothesis
An alternative way to conduct a hypothesis test is to again assume initially that the null hypothesis is true, but then to calculate the probability of observing a t-statistic as extreme as the one observed or even more extreme
For a lower-tail test, the p-value is the area under the curve of the t-distribution (with n−1 degrees of freedom) to the left of the observed t-statistic.
Lower-tail tests work in a similar way to upper-tail tests, but all the calculations are performed in the negative (left-hand) tail of the t-distribution density curve
A lower-tail test would result in an inconclusive result for the home prices example (since the large, positive t-statistic means that the data favor neither the null hypothesis, NH: E(Y) = 255, nor the alternative hypothesis, AH: E(Y) < 255).

how to solve 98,060 x 4
The value of 98,060 × 4 = 392240.
Distributive Property of Multiplication:
The distributive property of multiplication states that when we multiply a number by the total of two or more addends, the outcome is the same as when we multiply the number by each addend separately.
The sum and difference of two more numbers are both subject to the distributive property of multiplication.
According to the Distributive Property of Multiplication:
(A + B)C = AC + BC
Here we have
98,060 × 4
As we know 98060 = (98000 + 60)
= (98000 + 60) × 4
= (98000 × 4) + (60 × 4) [ ∵ (A + B)C = AC + BC ]

A rectangle has a length of 2X +4 and a width of X -7 what is the value of X if the perimeter of the rectangle measures 48
Answer:
Step-by-step explanation:
2(2x + 4) + 2(x-7) = 48
4x+8 +2x-14=48
6x-6 = 48
6x = 48+6
6x = 54
x = 54/6
x = 9
For the following two numbers, find two factors of the first number such that their product is the first number and their sum is the second number.
40,13
Answer: For the first number 40, one possible set of factors that have a product of 40 and a sum of 13 is (1,40) or (40,1) . Because 1*40=40 and 1+40 = 41
We can not have any other pair whose product is 40 and sum is 13 as it is not possible for any pair of factors of 40 to sum up to 13 as the only pair is (1,40) or (40,1) and their sum is 41
Step-by-step explanation:
An ice rink charges hockey teams for ice time to practice. The ice rink charges $10 for the first hour
and $12 for each additional hour. Write a function that represents the charges for up to 5 hours.
The function that represents the charges is [tex]t_{n}=[/tex] 10 + (n- 1 )12
What is the function representing the charges ?Here, let us apply Arithmetic sequence Let the charges for the first hour = a = $10 Let the common difference = d = $12The formula for the nth term is given by
[tex]t_{n}=[/tex] a +(n-1)d
The function that represents the charges is given by,[tex]t_{n}=[/tex] a +(n-1)d
[tex]t_{n}=[/tex] 10 + (n- 1 ) 12
a ) First hour
n = 1
[tex]t_{1 }=[/tex] 10 + (1- 1 ) 12
= 10
b ) Second hour
n = 2
[tex]t_{2 }=[/tex] 10 + (2- 1 ) 12
= 10 + 12
= 22
c ) Third hour
n = 3
[tex]t_{3}=[/tex] 10 + (3- 1 ) 12
= 10 + 24
= 34
d ) Fourth hour
n = 4
[tex]t_{4 }=[/tex] 10 + (4- 1 ) 12
= 10 + 36
= 46
e ) Fifth hour
n = 5
[tex]t_{4 }=[/tex] 10 + (5- 1 ) 12
= 10 + 48
= 58
