Answer:

The measure of arc SQ is 95° ⇒ (1)

Step-by-step explanation:

In the given circle

∵ S lies on the circumference of the circle

∴ ∠QSR is an inscribed angle

∵ ∠QSR is subtended by arc QR

→ By using the 2nd rule above

∴ m arc QR = 2 × m∠QSR

∵ m∠QSR = 95°

∴ m arc QR = 2 × 95

∴ m arc QR = 190°

→ By using the 1st rule above

∵ m of the circle = m arc QR + m arc SQ + m arc SR

∵ m arc SR = 75° and m arc QR = 190°

→ Substitute them in the equation above

∴ 360 = 190 + m arc SQ + 75

→ Add the like term in the right side

∴ 360 = 265 + m arc QS

→ Subtract 265 from both sides

∵ 360 - 265 = 265 - 265 + m arc SQ

∴ 95° = m arc SQ

∴ The measure of arc SQ is 95°

The probabilities are: a) P(B or Y) = 7/15, b) P(R or Y) = 2/3

To find the probability of certain events when drawing marbles from a jar, we need to consider the total number of possible outcomes and the number of favorable outcomes.

In this case, we have a jar containing 15 marbles, with 5 blue, 8 red, and 2 yellow marbles. Let's calculate the probabilities for the events:

a) P(B or Y) - The probability of drawing a blue or yellow marble.

Total number of marbles = 15

Number of blue marbles = 5

Number of yellow marbles = 2

Favorable outcomes = Number of blue marbles + Number of yellow marbles = 5 + 2 = 7

P(B or Y) = Favorable outcomes / Total number of marbles = 7 / 15

b) P(R or Y) - The probability of drawing a red or yellow marble.

Total number of marbles = 15

Number of red marbles = 8

Number of yellow marbles = 2

Favorable outcomes = Number of red marbles + Number of yellow marbles = 8 + 2 = 10

P(R or Y) = Favorable outcomes / Total number of marbles = 10 / 15

To simplify the fractions, we can check if there are any common factors between the numerator and denominator for each event.

For P(B or Y):

The numerator 7 and the denominator 15 have no common factors other than 1, so the fraction cannot be simplified further. Therefore, the probability P(B or Y) is 7/15.

For P(R or Y):

The numerator 10 and the denominator 15 both have a common factor of 5. By dividing both numerator and denominator by 5, we get 2/3. Therefore, the probability P(R or Y) is 2/3.

These probabilities represent the likelihood of drawing a blue or yellow marble (P(B or Y)) and a red or yellow marble (P(R or Y)) from the given jar, respectively.

a) The complete beta (ß) decay reaction for 60Co is 60 (superscript) 27 (subscript) Co → 60 (superscript) 28 (subscript) Ni + -1 (superscript) 0 (subscript) e.

b) The complete beta (ß) decay reaction for 18F is 18 (superscript) 9 (subscript) F → 18 (superscript) 10 (subscript) Ne + -1 (superscript) 0 (subscript) e.

Beta (ß) decay is a type of radioactive decay in which a beta particle, which can be either an electron or a positron, is emitted from the nucleus of an atom. It occurs when a neutron is converted into a proton or vice versa, along with the emission of a beta particle.

In the first given example, the beta (ß) decay of 60Co is represented as 60 (superscript) 27 (subscript) Co → 60 (superscript) 28 (subscript) Ni + -1 (superscript) 0 (subscript) e. This means that a cobalt-60 nucleus (with 27 protons and 33 neutrons) decays into a nickel-60 nucleus (with 28 protons and 32 neutrons) by emitting a beta particle, which is represented by -1 (superscript) 0 (subscript) e.

Similarly, in the second given example, the beta (ß) decay of 18F is represented as 18 (superscript) 9 (subscript) F → 18 (superscript) 10 (subscript) Ne + -1 (superscript) 0 (subscript) e. This indicates that a fluorine-18 nucleus (with 9 protons and 9 neutrons) decays into a neon-18 nucleus (with 10 protons and 8 neutrons) by emitting a beta particle.

Answer:

$130.7086

Step-by-step explanation:

List price of phone answering system = $99.86

Handset cord = $8.95

Telephone wire = 45 cent/foot ; length = 50 feet

Rebate on phone system = $5

Store coupon =$1 of each accessory

Sales tax = 6% on final price

Price before coupon = (99.86 + 8.95 + (50*0.45)) =$131. 31

Number of accessories = 3

Total coupon = $5 + ($1 * 3) = $8

Price after coupon = final price : $131.31 - $8 = $123.31

Sales tax = 0.06 * $123.31 = $7.3986

Amount paid = $123.31 + $7.3986 = $130.7086

Answer: 4 bags.

Step-by-step explanation:

50lb bag = 75sq.ft.

75*4= 300

50lb *4=200.

he required solution is \(y=c_1e^{2x}+c_2e^{-2x}+c_3\sqrt2\cos(\sqrt2x)+c_4\sqrt2\sin(\sqrt2x)\)

where \(c_1,c_2,c_3\) and \(c_4\) are constants.

Let’s assume the general solution of the given differential equation is,

y=e^{mx}

By taking the derivative of this equation, we get

\(\frac{dy}{dx} = me^{mx}\\\frac{d^2y}{dx^2} = m^2e^{mx}\\\frac{d^3y}{dx^3} = m^3e^{mx}\\\frac{d^4y}{dx^4} = m^4e^{mx}\\\)

Now substitute these values in the given differential equation.

\(\frac{d^4y}{dx^4}-2\frac{d^2y}{dx^2}-8y\\=0m^4e^{mx}-2m^2e^{mx}-8e^{mx}\\=0e^{mx}(m^4-2m^2-8)=0\)

Therefore, \(m^4-2m^2-8=0\)

\((m^2-4)(m^2+2)=0\)

Therefore, the roots are, \(m = ±\sqrt{2} and m=±2\)

By applying the formula for the general solution of a differential equation, we get

General solution is, \(y=c_1e^{2x}+c_2e^{-2x}+c_3\sqrt2\cos(\sqrt2x)+c_4\sqrt2\sin(\sqrt2x)\)

Hence, the required solution is \(y=c_1e^{2x}+c_2e^{-2x}+c_3\sqrt2\cos(\sqrt2x)+c_4\sqrt2\sin(\sqrt2x)\)

where \(c_1,c_2,c_3\) and \(c_4\) are constants.

Each twelve-inch square tile weighs approximately 27 ounces.

To calculate the weight of each tile in ounces, we need to convert the weight of the box from pounds to ounces and divide it by the number of tiles in the box. Since there are 16 ounces in a pound, the weight of each box is 36 pounds * 16 ounces/pound = 576 ounces.

If there are 20 tiles in each box, we divide the weight of the box (576 ounces) by the number of tiles (20) to get the weight of each tile: 576 ounces / 20 tiles = 28.8 ounces. Rounding to the nearest ounce, each twelve-inch square tile weighs approximately 27 ounces.

If the deposited amount is $2600 and amount after 4 years is $3238.17 then the annual rate of interest will be 6%.

Given that the deposited amount is $2600 and amount after 4 years is $3238.17.

We are required to find the rate of interest for the given data.

Compound interest is the interest that is calculated on the aggregate amount and the interest.

S=P\((1+r/m)^{mn}\), in which S is the amount after compounding, P is amount in the beginning, m is number of times of compounding and n is the number of periods of compounding.

We have to use the values in the above formula to get the rate of interest.

3238.17=2600\((1+r/12)^{48}\)      

(In our case the amount is compounded monthly so the value of m is 12)

3238.17/2600=\((1+r/12)^{48}\)

1.24545=\((1+r/12)^{48}\)

\(1.24545^{1/48}\)=1+r/12

Take log both sides.

log \(1.24545^{1/48}\)=log(1+r/12)

1/48 log (1.24545)=log (1+r/12)      (log \(m^{n}\)=n log m)

1/48 *0.09532=log(1+r/12)

0.00198=log(1+r/12)

Al(0.00198)=(1+r/12)            (Al=Antilog)

1.0045695=1+r/12

0.0045695=r/12

r=0.0548

r=5.5%

It will be 6% after rounding.

The percent decrease in the price of the headphones is 26.32%.

Explanation:

To find the percent change in price, we can use the following formula:

percent change = (new value - old value) / old value * 100%

     
In this case, the old value is the original price of the headphones, which is $95.
   

The new value is the sale price, which is $70. Plugging these values into the formula, we get:percent change = (70 - 95) / 95 * 100%

percent change = -25 / 95 * 100%

percent change = -0.2632 * 100%

percent change = -26.32%

   
The negative sign indicates that the price has decreased, and the magnitude of the percent change is 26.32%, which means that the sale price is 26.32% lower than the original price.

To calculate the distance needed to stop at the red light, we can use the kinematic equation:

v_f^2 = v_i^2 + 2aΔx

where:

v_f = final velocity (which is 0 m/s since the car needs to stop)

v_i = initial velocity (60 km/h converted to m/s)

a = acceleration (deceleration in this case, which is -2.5 m/s^2)

Δx = distance

Converting the initial velocity from km/h to m/s:

v_i = 60 km/h * (1000 m/1 km) * (1 h/3600 s) ≈ 16.67 m/s

Plugging the values into the equation and solving for Δx:

0^2 = (16.67 m/s)^2 + 2 * (-2.5 m/s^2) * Δx

Simplifying the equation:

0 = 277.89 m^2/s^2 - 5 m/s^2 * Δx

Rearranging the equation to solve for Δx:

5 m/s^2 * Δx = 277.89 m^2/s^2

Δx = 277.89 m^2/s^2 / 5 m/s^2

Δx ≈ 55.578 m

Therefore, the distance needed to stop at the red light is approximately 55.578 meters.

To find the value of the effective spring constant (k), we are given the masses of oxygen (16.0 atomic mass units) and carbon (12.0 atomic mass units). We will use this information to determine the value of k.

The effective spring constant (k) is a measure of the stiffness of the spring and is usually given in units of force per unit length or mass per unit time squared. In this case, we need to determine k based on the masses of oxygen and carbon.

To find k, we can use the formula for the effective spring constant in a molecular vibration system, which is given by:

K = (ω^2)(μ)

Where ω is the angular frequency of the vibration and μ is the reduced mass of the system.

Since we are given the masses of oxygen and carbon, we can calculate the reduced mass (μ) as follows:

Μ = (m1 * m2) / (m1 + m2)

Where m1 and m2 are the masses of oxygen and carbon, respectively.

Using the given masses:
M1 = 16.0 atomic mass units (oxygen)
M2 = 12.0 atomic mass units (carbon)

We can substitute these values into the equation for μ:

Μ = (16.0 * 12.0) / (16.0 + 12.0)
= 192.0 / 28.0
≈ 6.857 atomic mass units

Now, to find the value of k, we need the angular frequency (ω) of the vibration. Unfortunately, the angular frequency is not provided in the given information. Without the angular frequency, we cannot determine the exact value of k.

Therefore, we can calculate the reduced mass (μ) using the given masses of oxygen and carbon, but we cannot find the value of k without the angular frequency.
