Step-by-step explanation:

Arc length is defined as:

s = rθ

where r is the radius and θ is the angle in radians

A unit circle has a radius of 1, so the arc length is equal to the radian measure of the angle.

The radian measure determines the arc length on the unit circle using the formula s = θ for a unit circle (radius = 1). Radians, being a ratio of arc length to radius, allow for direct conversion between angle and arc length, facilitating calculations and conversions between radians and degrees.

The radian measure of an angle can determine the arc length on the unit circle by using the formula arc length (s) = radius (r) × angle in radians (θ). Since the unit circle has a radius of 1, this simplifies to s = θ. The concept of radians is crucial here; a radian is defined as the ratio of the arc length to the radius of the circle, making it a dimensionless unit. This relationship remains constant regardless of the circle's size, meaning the radian measure directly gives the arc length on the unit circle.

For a full revolution of 2π radians (360 degrees), the arc length is equal to the circumference of the circle, which is 2πr. In the case of the unit circle, this equates to an arc length of 2π. This principle allows for the conversion between radians and degrees, and calculation of arc lengths for any given angle measured in radians.

Answer:

8 years

Step-by-step explanation:

An initial investment of $100 is now valued at $150. The annual interest rate is 5%, compounded continuously. The equation [tex]100e^{0.05t} = 150[/tex] represents the situation, where t is the number of years the money has been invested.

To find out how long has the money invested we need to find out 't'

[tex]100e^{0.05t} = 150[/tex] , solve for t

divide both sides by 100

[tex]e^{0.05t} = 1.5[/tex]

Now to remove 'e' we take ln on both sides

[tex]ln(e^{0.05t) = ln 1.5[/tex]

the value of [tex]ln(e)= 1[/tex]

[tex]0.05t = ln 1.5[/tex]

Now divide by 0.05 on both sides

t = 8.10930

The money is invested for 8 years

I took the test.

Answer:

No, the answer is not reasonable. It should be about 10 pounds.

Step-by-step explanation:

Given,

The quantity of hot dog bought by Jill's club = [tex]4\frac{2}{5}[/tex] pounds,

Hot dog = [tex]3\frac{1}{2}[/tex] pounds

Hamburger = [tex]2\frac{3}{10}[/tex] pounds

So, the total quantity of meat they bought

[tex]=4\frac{2}{5}+3\frac{1}{2}+2\frac{3}{10}[/tex]

[tex]=\frac{22}{5}+\frac{7}{2}+\frac{23}{10}[/tex]

[tex]=\frac{44+35+23}{10}[/tex]  ( Adding fractions ),

[tex]=\frac{102}{10}[/tex]

[tex]=10.2\text{ pounds}[/tex]

Since, [tex]8\frac{1}{2}=\frac{17}{2}=8.5[/tex]

[tex]\implies 8.5\neq 10.2[/tex]

Hence, the student's answer is not reasonable it should be about 10 pounds.

Answer:

x = 46°

Step-by-step explanation:

The angle 69° and z form a straight angle and are supplementary, thus

z = 180° - 69° = 111°

The sum of the 3 angles in a triangle = 180°, hence

x = 180° - (111 + 23)° = 180° - 134° = 46°

Question 1: x = 0,6,4

Step-by-step explanation:

#1. If we let x be the side of the cut-out square, the formula for the volume of the box is

[tex]\text{Volume} = (12 - 2x)(8 - 2x)(x).[/tex]

Expanding gives us

[tex]\text{Volume} = 4x^3 - 40x^2 + 96x. [/tex]

To find the zeros, we need to set the equation to 0, and the values of x that would result to zero would be:

[tex]x = 0, 6, 4[/tex]

As how it is told 'he' wanted to make a box with no lid for his marble connection, 'he' wants to cut out four "Identical" squares from all of the corners of the sheet (which I'm assuming is that there is four corners) and by doing so he then wants to fold all the sides...

So he buys one that is 8 by 12 inches, so you can draw a box that is (8, 12) put an 'x' at all four corners and 'cut' it the corners out.

Here's the formula that you can use... Which could be either one I guess..

-Cube = a 3

-- a is the side length

-Rectangular prism = a * b * c

-- a, b, c are the length, width, and height

The volume of a cube is side times side times side. Since each side of a square is the same, it can simply be the length of one side cubed. If a square has one side of 4 inches, the volume would be 4 inches times 4 inches times 4 inches, or 64 cubic inches.

Once you found a function I think you should use the quadratic equation, which is- y=x2-20x+96

And you could use that equation to graph it out... But if they want it to be the volume of 12 cubic inches then er-... Yeah that's were i'm stumped at... My apologies..

Answer:

25%

Step-by-step explanation:

350/1400 as a simplified fraction is 1/4 because you can divide 350 into 1400.

And now we know that 1/4 is 25%.

Or just divide 1 by 4. And you'll get .25 and then just move the decimal to the right 2 times.

Hope this helps!

Harold gave 1,400 stamps to his brother and sister. He gave 350 stamps to his brother. What percent of stamps did Harold give to his brother.

The percent[tex]\frac{350}{1,400}[/tex] represents the number of stamps that Harold gave to his brother out of all the stamps.

To find what percent of stamps that Harold gave to his brother, we can change the fraction [tex]\frac{350}{1,400}[/tex] to a percent.

We can first reduce this fraction by dividing both the numerator and denominator by the Greatest Common Factor of 350 and 1400 using 350.

350 ÷ 350 = 1

1400 ÷ 350 = 4

Our reduced fraction is [tex]\frac{1}{4}[/tex].

1 ÷ 4 = 0.25

0.25 × 100 = 25%

Therefore, Harold gave his brother 25% of his stamps.

Step-by-step explanation:

a. The problem tells me that for every 3 parts of red paint, I have 8 parts of yellow paint. To find the ratio of 1 part of yellow paint I can write the following statement

For 8 parts of yellow paint ------------ 3 parts of red paint

        1 part of yellow paint  -------------      x

So [tex]x=\frac{1 part of yellow paint * 3 parts of red paint }{8 parts of yellow paint}[/tex]

[tex]x= \frac{3}{8} parts of red paint[/tex]

b, I have the following relationship

3 parts of red paint ----- 8 parts of yellow paint

If I multiply the entire expression by 3 I have left

3 * 3 parts of red paint -------- 8 * 3 parts of yellow paint

So

9 parts of red paint ---------- 24 parts of yellow paint

c.I have the same relationship

3 parts of red paint ----- 8 parts of yellow paint

If I multiply the entire expression by 1/2 I have left

3/2 parts of red paint -------- 8/2 parts of yellow paint

So

3/2 parts of red paint ---------- 4 parts of yellow paint

as 3/2 is different from 10, then the approach is false

d. observing the relation of part a,

For 3 parts of red paint ------------ 8 parts of yellow paint

      1 part of red paint   -------------      x

So [tex]x=\frac{1 part of red paint * 8 parts of yellow paint }{3 parts of red paint}[/tex]

[tex]x= \frac{8}{3} parts of yellow paint[/tex]  that is different than 3/8 parts of yellow paint, then the approach is false

Step-by-step explanation:

The publisher should produce and sell approximately 4480 books in order to break even on the total costs of production.

The problem requires figuring out when the revenues from selling the book will equal the total cost of production. This is a problem in algebra.

The one-time fixed costs total $45,920, and the variable costs per book are $11.25. The books will be sold for $21.50 each.

Step 1: Set up an equation

Let x be the number of books that need to be sold. The equation is then: 45920 + 11.25x = 21.50x.

Step 2: Solve for x

Subtract 11.25x from each side to isolate the variable on one side giving you: 10.25x = 45920. Then, divide both sides by 10.25 to derive x. So, the equation is x = 45920 / 10.25.

Step 3: Derive the solution

By doing the calculation, x approximately equals 4480. Thus the publisher needs to sell just about 4480 books to break even.

The publisher must produce and sell 4,478 books to cover total production costs. They need to break even by equating total costs with total revenue, using the formula FC + (VC × N) = P × N, and solving for N after substituting the given fixed costs, variable costs per book, and price per book.

To determine how many books a publisher must produce and sell to cover production costs, the following formula is used:

To break even, TC must equal TR. This can be expressed as:

FC + (VC × N) = P × N

Now we substitute the given values:

$45,920 + ($11.25 × N) = $21.50 × N

To find N, we solve the equation for N:

Therefore, the publisher must produce and sell 4,478 books to cover total production costs.

The rocket exceed the height of 500 ft in 1.46 seconds or 8.43 seconds.

Standard form of the quadratic equation in the variable x is an equation of the form a[tex]x^{2}[/tex] + bx + c = 0, where a, b, c are real numbers and a ≠ 0. Any equation of the form P(x) = 0, Where P(x) is a polynomial of degree 2, is a quadratic equation.

Given equation of height is:

h(t)= -[tex]16t^{2} +160t+300[/tex]

Now, the exceeded to 500 feet.

So,

-[tex]16t^{2} +160t+300[/tex]=500

16[tex]t^{2}[/tex] -160 t +200=0

Now, solve for t: a=16, b= -160, c= 200

D= [tex]\sqrt{b^{2}-4ac }[/tex]

 = [tex]\sqrt{(-160)^{2}-4*16*200 }[/tex]

As D>0 then,

x= [tex]\frac{-b\pm \sqrt{b^{2}-4ac }}{2a}[/tex]

x= (160 ±80√2)/32

x=  (160 +80√2)/32   or x= (160 -80√2)/32

Step-by-step explanation:

R can be as small as -1 to display a perfect negative linear relationship or as large as 1 to display a perfect positive linear relationship. The closer the r-value is to 0 the weaker the correlation so therefore 0.2 is closest to 0 making it the answer choice with the weakest correlation.

Answer:

On the graph B, at 0 seconds the graph will be at [tex]y=0.[/tex]

The graph will be going down until 2 seconds, when the diver reaches her deepest point. At 2 seconds the height of the graph will be -8ft.

Step-by-step explanation:

In graph B we are measuring the distance from the surface, that is we are setting the surface to be y=0. Thus if the diver reaches her deepest point 8ft down, she will be below y=0 and at -8ft.

Thus, in shape the graph B will be similar to graph A, but it will be shifted downed by 8ft.

Answer:

On Graph B, at 0 seconds, the graph will be at 0 feet.

Then the graph will increase until 2 seconds, when the diver reaches her deepest point. At 2 seconds the height of Graph B will be at 8 feet.

Answer:4/5

Step-by-step explanation:

Answer:

I believe the answer is 110.

Answer:

Step-by-step explanation:

In this problem we need to use the Inscribed Angle theorem, which states that an inscribed angle is one-half its subtended arc.

[tex]\angle C=\frac{1}{2}arc(DB)=70\°[/tex]

Then, we use the theorem about a cyclic quadrilateral, which is an inscribed quadrilateral: "the opposite angles in a cyclic quadrilateral are supplementary".

[tex]\angle C + \angle A = 180\°\\\angle A = 180\° - \angle C\\\angle A = 180\° - 70\° \\\angle A = 110\°[/tex]

Therefore, the answer is 110°

given sides,

a=36

b=45

c=27

From cosine law,

cosA=

[tex] \frac{ {b}^{2} + {c}^{2} - {a}^{2} }{2bc} \\ = \frac{ {45}^{2} + {27}^{2} - {36}^{2} }{2 \times 45 \times 27} \\ = \frac{3}{5} = 0.6[/tex]

or, A= cos^-1(0.6)=53.13°

similarly, cosB=

[tex] \frac{ {a}^{2} + {c}^{2} - {b}^{2} }{2ac} \\ = \frac{ {36}^{2} + {27}^{2} - {45}^{2} }{2 \times 36 \times 27} \\ = 0[/tex]

or, B= cos^-1(0)=90°

Since, B=90, the given triangle is right angled triangle.
