b) 5.2 in
c) 3.3 in
d) 20.9 in
Answer: its A
Step-by-step explanation:
Any smooth curve connecting two points is called an arc. The length of arc s to the nearest tenth is 10.5 in.
What is the Length of an Arc?Any smooth curve connecting two points is called an arc. The arc length is the measurement of how long an arc is. The length of an arc is given by the formula,
[tex]\rm{ Length\ of\ an\ Arc = 2\times \pi \times(radius)\times\dfrac{\theta}{360} = 2\pi r \times \dfrac{\theta}{2\pi}[/tex]
where θ is the angle, which arc creates at the center of the circle in degree.
The length of the given arc s, with an angle made at the center equal to (2/3)π and radius of 5 inches can be represented as,
[tex]\text{Length of Arc} = 2\pi r \times \dfrac{\theta}{2\pi}[/tex]
[tex]\text{Length of Arc s} = 2\pi \times (5)\times \dfrac{\frac23\pi}{2\pi}[/tex]
[tex]=10.472\approx 10.5\rm\ in[/tex]
Thus, the length of arc s to the nearest tenth is 10.5 in.

mike had a balance of $175 in his bank account at the start of the week.He withdrew $65.00 on Monday, $43.25 on Wednesday, and $56.45 on Thursday.On Friday he deposited $165.30.
1.At the end of the week, does Mike have more or less money in his savings account than he had at the beginning of the week?
2.How much more or less?
3.Show all of your work to support your answers.
Answer:
1. Mike has more money in his savings account than he had at the beginning of he week
2. $0.6 more
3. Current Balance is $175 + $165.30 - $164.7 = $175.6
Step-by-step explanation:
The question is of the format of a word problem, hence we have;
Initial balance in Mike's bank account = $175
Withdrawal on Monday = $65.00
Withdrawal on Wednesday = $43.25
Withdrawal on Thursday = $56.45
Deposit on Friday = $165.30
Total withdrawal = $164.7
Therefore we have;
Current Balance = Initial balance + total deposit - total withdrawal
∴ Current Balance = $175 + $165.30 - $164.7 = $175.6
1. Therefore, based on the above calculations, Mike has more money in his savings account than he had at the beginning of he week
2. Mike has $0.6 more.
3. Current Balance = Initial balance + total deposit - total withdrawal
∴ Current Balance = $175 + $165.30 - $164.7 = $175.6.

Answer:
To find x, y, z, p and q, you need to know about the property of Rhombus.
13y + 10 = 7y + 16 (pair of equal opposite sides)
=> 6y = 6
=> y = 1
x = 7x + 16 (2 equal adjacent sides)
= 7*1 + 16
=23
z = 90 deg (angle between 2 diagonals)
q = 22 deg (isosceles triangle)
p = 90 - 22 = 68 deg (right triangle)

consider the following three equations:
linear: y=20x+300
Quadratic: y=5x^2
Exponential: y=10(1.4)^x
use the equations to answer the following questions. Support your answers with work.
1. At an x-value of 11, which equation has the largest y-value?
2. what is the smallest integer value of x for which the value of the exponential equation is greater than the values of both the linear and quadratic functions?
Answer:
1.
y = 20(11) + 300 = 520
y = 5(11)(11) = 605
y = 10(1.4)^11 = 404.96
hence the quadratic formula - y = 5x^2 has the largest y-value
2.
y = 20 (14) + 300 = 580
y = 5 (14) (14) = 980
y = 10(1.4)^ 14 = 1111.20 > this is greater than both equations above
14 is the smallest value of x for which the value of the exponential equation is greater than the values of both the linear and quadratic functions
Step-by-step explanation:
Answer:
1. Quadratic
2. x = 14
Step-by-step explanation:
1. At x = 11
linear: y=20(11) + 300 = 520
Quadratic: y=5× 11² = 605
Exponential: y=10(1.4)¹¹ = 404.956517
2. 10(1.4^x) > 20x + 300
1.4^x > 2x + 30
1.4^x - 2x - 30 > 0
Using trial method:
x > 11
10(1.4^x) > 5x²
1.4^x - 0.5x² > 0
Using trail method:
x > 13
The smallest positive integer which satisfies both inequalities is 14

Dana is purchasing a new car that costs $24,650. The bank is charging 4% simple interest for 6 years to finance the car. Using I = PRT, where I represents the amount of interest, P equals the amount financed, R represents the interest rate as a decimal, and T represents the number of years the car is financed, how much interest will Dana pay?
Answer:
5,916
[tex]24650 \times 0.04 \times 6 = 5916[/tex]
The interest that should be paid by Dana at the time when the new car cost should be $24,650. So it is $5,916.
Calculation of the interest:Since Dana is purchasing a new car that costs $24,650. The bank is charging 4% simple interest for 6 years to finance the car.
So here the calculation is
= $24,650 (4%)(6 year)
= $5,916
Hence, The interest that should be paid by Dana at the time when the new car cost should be $24,650. So it is $5,916.

Answer:
Let x be the number of tickets sold to adults and y the number sold to students:
x + y = 315. But we know that y was double x, then :
y = 2x
Plug the value of y (in the 1st equation) by 2x:
x+ 2x = 315

PLEASE MARK BRAINIEST!!
The required value of cos θ is approximately -0.95.
What are Trigonometric functions?Trigonometric functions are defined as the functions which show the relationship between the angle and sides of a right-angled triangle.
We are given that sin θ = -0.31 and π < θ < 3π/2.
Since sin θ = -0.31 is negative, we know that θ is in the third quadrant.
Using the identity 2θ + 2θ = 1,
We can rewrite it as:
2θ = 1 - 2θ.
Squaring both sides, we get:
4θ² = 1 - 4θ + 4θ²
Simplifying, we get 8θ = 1, which means θ = 1/8π.
Since θ is in the third quadrant, we have cos θ < 0.
Using the identity cos² θ + sin² θ = 1, we can solve for cos θ as follows: cos² θ = 1 - sin² θ
cos² θ = 1 - (-0.31)²
cos² θ = 0.9039
cos² θ ≈ -0.95
Therefore, the value of cos θ is approximately -0.95.

Pi ends after how many decimal places?
Answer:
31.4 trillion decimal places but no one really knows how many decimal places there are. 31.4 trillion decimal places is a world record set by google
Step-by-step explanation:
Answer:
`31.4 trillion decimal places.
Explanation:
As far as we know Google found out that there is about 31.4 trillion decimal places which is rounded to 3.14. Google is not 100% accurate though, Pi is a mathematical number that never ends so we just use what we know which is 3.14. Pi is an ideal that in numerical terms can be approached, but never reached. In order to calculate Pi simply involves taking any circle and dividing its circumference by its diameter. William Jones is the "founder" of Pi in 1706. Jones was a British little-known mathematics teacher, Jones was the first person to use a symbol to represent the platonic concept of Pi.
