280°

Answers

Let's consider what the problem wants us to find:

fractional part covered by the labeled angleangle in radians

Let's find the fractional part:

 ⇒ the fractional part is equal:

       [tex]\frac{degree-covered-by-angle}{total-angle} =\frac{280}{180} =\frac{2*2*7*10}{2*2*3*3*5} =\frac{7*10}{3*3*5} =\frac{70}{45}=\frac{14}{9}[/tex]

  Answer: The angle 280 degrees covers 14/9 of a semicircle.

Let's find the angle measure in radians:

 ⇒ we know that [tex]2\pi[/tex] radians are equal to 360 degrees

    ⇒ to convert any degree to radians, you must multiply [tex]\frac{\pi }{180}[/tex]

        so [tex]280*\frac{\pi }{180} =\frac{28}{18}*\pi =\frac{28\pi }{18}=\frac{2*14*\pi }{2*9} =\frac{14\pi }{9}[/tex]

 Answer: The angle 280 degrees in radians is [tex]\frac{14\pi} {9}[/tex] which in terms of [tex]\pi[/tex] is

Charles needs a $10,000 loan in order to buy a car. Which loan option would allow him to pay the LEAST in interest? A) A 2-year loan with a 4. 75% interest rate compounded annually. B) A 3-year loan with a 4. 00% interest rate compounded annually. C) A 4-year loan with a 3. 75% interest rate compounded annually. D) A 5-year loan with a 3. 00% interest rate compounded annually

Answers

The loan option that would allow Charles to pay the LEAST in interest is option A.

What is Compound Interest?

Compound Interest is a process where the interest is credited to the initial amount and interest, on the whole, is charged again. and this continues for t period of time.

It is given by the formula,

[tex]A=P(1+r\%)^n[/tex]

where A is the value after t period of time, P is the principal amount, and,

r is the rate of interest.

A.) Principle amount = $10,000

Time Period of loan = 2 years

Rate of Interest = 4.75% per annum

Now, the total amount can be written as

[tex]=P(1+r\%)^n\\\\= \$10,000 \times (1+0.0475)^2\\\\= \$10,972.56[/tex]

The interest will be = $10,972.56 - $10,000 = $972.56

B.)  Principle amount = $10,000

Time Period of loan = 3 years

Rate of Interest = 4.00% per annum

Now, the total amount can be written as

[tex]=P(1+r\%)^n\\\\= \$10,000 \times (1+0.04)^2\\\\= \$11,248.64[/tex]

The interest will be = $11,248.64 - $10,000 = $1,248.64

C.) Principle amount = $10,000

Time Period of loan = 4 years

Rate of Interest = 3.75% per annum

Now, the total amount can be written as

[tex]=P(1+r\%)^n\\\\= \$10,000 \times (1+0.0375)^2\\\\= \$11,586.5[/tex]

The interest will be = $11,586.5- $10,000 = $1,586.5

D.) Principle amount = $10,000

Time Period of loan = 5 years

Rate of Interest = 3.00% per annum

Now, the total amount can be written as

[tex]=P(1+r\%)^n\\\\= \$10,000 \times (1+0.03)^5\\\\= \$11,592.74[/tex]

The interest will be = $11,592.74 - $10,000 = $1,592.74

Hence, the loan option that would allow Charles to pay the LEAST in interest is option A.

Answers

The answer will be t=-35Sin{[tex]\pi[/tex]/6m)+55 average daily temperature, t, in degrees Fahrenheit for a city as a function of the month of the year.

What is temperature?

Temperature is the degree or intensity of heat present in a substance or object, especially as expressed according to a comparative scale and shown by a thermometer or perceived by touch.

For the equation: 35cos(pi/6(m+3)+55)

Simplify it by multiplying pi/6 in the bracket values:  

[tex]=35 Cos (\dfrac{\pi m}{6}+\dfrac{3\pi }{6}+55)[/tex]

[tex]=35 Cos(\dfrac{\pi m}{6}+55+\dfrac{\pi}{2})[/tex]

Now suppose x = m.pi/6+55, while pi/2 = 90⁰

As per law cos(x+90⁰)=-sin(x)

so,cos((m.pi/6)+55+90⁰=-sin((m.pi/6)+55)

Hence answer will be

[tex]=-35Sin(\dfrac{\pi m}{6}+55)[/tex]

The law cos(x+90⁰)=-sin(x) can be proved by putting y=90⁰ in the following formula,

cos(x+y)=cos(x).cos(y)-sin(x).sin(y)

Hence the answer will be t=-35Sin{[tex]\pi[/tex]/6m)+55 average daily temperature, t, in degrees Fahrenheit for a city as a function of the month of the year.

How to calculate the distance between two points

The formula for calculating the distance between two coordinates is expressed as:

D = √(x2-x1)²+(y2-y1)²

Given the coordinate points A (-3,2) and B (1,0), the length of the line segment that has the endpoint is given as:

D = √(0-2)²+(1+3)²
D = √(2)²+(4)²
D = √16+4

For w :

The formula of Ohm's low is V=IR

[tex]I=\dfrac{V}{R}[/tex]

[tex]I=\dfrac{18\ V}{38\ \Omega}[/tex]

I=0.47

[tex]q=0.47\times8[/tex]

So charge,q=It

q=3.76\ C

For x :

Voltage, V=24\ V

[tex]resistance, R=34\ \Omega[/tex]

so, V=IR...(Ohm's low)

[tex]I=\dfrac{V}{R}[/tex]

[tex]I=\dfrac{24\ V}{34\ \Omega}[/tex]

I=0.705

[tex]q=0.705\times8[/tex]

So charge,q=It

q=5.64\ C

For y :

Voltage, V=34\ V

resistance, [tex]R=70\ \Omega[/tex]

so, V=IR.......(Ohm's low)

[tex]I=\dfrac{V}{R}[/tex]

[tex]I=\dfrac{34\ V}{70\ \Omega}[/tex]

I=0.485

[tex]q=0.485\times8[/tex]

So charge,q=It

q=3.88\ C

For z :

Voltage, V=12\ V

resistance, [tex]R=18\ \Omega[/tex]

so, V=IR......(Ohm's low)

[tex]I=\dfrac{V}{R}[/tex]

[tex]I=\dfrac{12\ V}{18\ \Omega}[/tex]

I=0.66

[tex]q=0.66\times8[/tex]

So charge,q=It

q=5.28\ C

Therefore, the circuits X and Z deliver 5.64 C and 5.28 C of charge.

Answer:

Radius of the cylinder is 18 yards

Step-by-step explanation:

Given:

Height of cylinder (H) = 15 yardsVolume of cylinder = 15,260 yd³

To Find:

Radius of the cylinder

Solution:

Here we are given height and volume of the cylinder. To find the radius of the cylinder We will substitute the value of height and volume in give formula:

Volume of cylinder = πr²h

➝ 15,260.4 = 22/7 × (r)² × 15

➝ 15,260.4 = (r)² × 330/7

➝ 15,260.4 = (r)² × 47.1

➝ 15,260.4/47.1 = (r)²

➝ 324 = (r)²

➝ √324 = r

➝ 18 = r

Hence,

Radius of cylinder is 18 yards
