Answer:

The answer would be B

Step-by-step explanation:

The charge on the object a is 0.00017 micro Coulombs (0.00017 μC) to two significant figures.

The electric force between two objects is given by Coulomb's law: F = k[tex]q_1[/tex][tex]q_2[/tex] /[tex]r^2[/tex], where k is the Coulomb constant, [tex]q_1[/tex]and [tex]q_2[/tex]  are the charges of the two objects, and r is the distance between them.

We have , [tex]q_2[/tex] = b

r = 50cm = 0.5m

k = 9 x [tex]10^9[/tex] [tex]Nm^2/C^2[/tex]

We know that b has a mass of 300 g and that a has twice the charge of b. So we can substitute these values and solve for [tex]q_1[/tex]:

[tex]q_1[/tex]= 2 * [tex]q_2[/tex]

[tex]q_2[/tex] = 0.38 N * [tex]0.5^2[/tex] / k

Substituting the values in Coulomb's law we get,

[tex]F = k q_1 q_2/r^2[/tex]

0.38 N = k * [tex]q_1[/tex] * [tex]q_2[/tex] /  [tex]0.5^2[/tex]

[tex]q_2[/tex]  = 0.38 N * [tex]0.5^2[/tex] / (9 x      [tex]10^9[/tex])

[tex]q_2[/tex]  = 0.00085 *  [tex]10^{-6}[/tex]

then we can multiply [tex]q_2[/tex]  by 2 to find the charge on object a:

[tex]q_1[/tex] = 2 * [tex]q_2[/tex]

[tex]q_1[/tex]= 0.00017 x [tex]10^{-6}[/tex] C

So, the charge on the object a is 0.00017 micro Coulombs (0.00017 μC) to two significant figures.

The quotient of the expression is 8 × 10² and option C is the correct answer.

The way of representing huge numbers in terms of powers is known as an exponent. Exponent, then, is the number of times a number has been multiplied by itself.

Adding exponents while maintaining the same base is the rule for multiplying like bases.

Exponents should be multiplied while bases are kept constant when bases are raised by a power of two or more.

Division Rule: When dividing like bases, maintain the base constant and deduct the exponent of the denominator from the exponent of the numerator.

Rewrite as fraction:

[tex]\frac{(5.04) (10^{12})}{(6.3)(10^9)}[/tex]

Simplify using exponent rule with same base [tex]\frac{a^n}{a^m} = a^{(n-m)}[/tex]:

[tex]\frac{(5.04) (10^{12-9})}{(6.3)}[/tex]

Calculate the sum or difference:

[tex]\frac{(5.04) (10^{3})}{(6.3)}[/tex]

Convert fraction into decimal: 0. 8 × 10³ = 8 × 10².

If a bus company usually transports 12 000 people per day at a ticket price of $1. The ticket price that will maximize revenue is $2 per ticket.

Equation to find the ticket price is:

y = (12000 - 400x)(1 + .1x)

Take the derivative of the function by product rule

y' = (12000 - 400x)(.1) + (-400)(1 + .1x)

y' = 1200 - 40x - 400 - 40x

y' = 800 - 80x

Let y' = 0

0 = 800 - 80x

Solving for x

80x = 800

Divide both side by 80x

x = 800/80

x = 10

Point at x = 10

Substitute x with 10 for 1 + .1x

The amount of interest due on the account is $8.36.

The interest on a loan or deposit can be calculated using simple interest. In order to calculate it, multiply the principal amount by the interest rate and then by the number of time periods (usually in years).

We must first determine the number of days for which the interest will accrue in order to calculate the amount of interest owed on the account. Since the charge was made on the 28th day after the payment was made on the 9th day, the interest will accrue for 19 days instead of the 28 since the payment was made.

We then use the formula for simple interest: Interest = Principal x Rate x Time

In this instance, the Principal is the initial balance of $660, the Rate is the annual percentage rate (APR), which needs to be converted to decimal form by dividing by 100, and the Time is the total number of days over which interest will accrue (19 days).

The Interest = $660 × 0.26 × (19/365) = $8.36

Thus, the total amount of interest due on the account is $8.36.

Using Angle Sum property, the measure of 3 angles is ∠Q = 35°, ∠R = 19°, ∠S = 126°.

According to the triangle's "angle sum property," a triangle's angles add up to 180 degrees. Three sides and three angles, one at each vertex, make up a triangle. The sum of the interior angles in a triangle is always 180o, regardless of whether it is acute, obtuse, or right.

One of the most commonly applied properties in geometry is the triangle's angle sum property. Most often, the unknown angles are calculated using this attribute.

As given the measure of 3 angles is -

∠Q = 4x - 17

∠R = x + 6

∠S = 10x - 4

We know that by angle - sum property,

The sum of 3 angles of triangle = 180°

⇒ 4x - 17 + x + 6 + 10x - 4 = 180

⇒ 15x -15 = 180

⇒ 15x = 180 + 15

⇒ 15x = 195

⇒ x = 13

∠Q = 4x - 17 = 4 × 13 - 17 = 35°

∠R = x + 6 = 13 + 6 = 19°

Answer: Yes

Step-by-step explanation:

First You need to find a common denominator between 5/8 and 3/5 so you can add them together.

The earliest common denominator between 8 and 5 is 40.

So you have to Multiply the numerator by whatever it takes the denomintor to reach 40.

So for 8 to reach 40 you have to multiply 8 by 5 so you must also multiple the numerator by 5 giving you 25 so your fraction becomes 25/40.

If you do the same for the other fraction you end with 24/40.

so 25/40 + 24/40 = 49/40 which is greater than 1

y = $40 is the equation of the line that represents the information. The line has no slope.

A linear equation can be used to represent the equation that represents Mr. Williams' total payment for city water. A linear equation is one that is composed of a single variable raised to the power of one.

Step-by-step explanation:

the easiest way might be the approach to calculate the area of the whole rectangle and then subtract the area of the triangle.

the area of the whole rectangle is

18×16 = 288 m²

the area of a triangle is

baseline × height / 2

in a case like this (right-angled triangle) we can use one leg as baseline, and the other leg (90°) as height.

so, the height is the same as the width of the rectangle : 16 m.

how long is the baseline ?

it is on the 18 m length of the rectangle, and there are two 3 m "gaps", one left, and one right.

so, what's left for the baseline of the triangle itself ?

baseline = 18 - 3 - 3 = 12 m

therefore the area of the triangle is

12×16/2 = 12×8 = 96 m²

so, the total area of the shaded region is

288 - 96 = 192 m²

Answer: The elimination method is a method for solving a system of equations by eliminating one of the variables. One way to do this is to multiply one equation by a constant and then add or subtract it from the other equation to cancel out one of the variables.

We will start by multiplying the first equation by 3:

2x + 6y = 2 ----> 6x + 18y = 6

Now we will subtract the second equation from the modified first equation:

6x + 18y = 6

(2x + 2y = 2)

4x + 16y = 4

Now we can solve for one of the variables, we will solve for x:

4x = 4

x = 1

Now that we know x = 1, we can substitute this back into one of the original equations, for example the first one:

2x + 6y = 2

2(1) + 6y = 2

6y = 0

y = 0

So the solution to the system of equations is x = 1 and y = 0

Therefore, the solution is (1,0)

Declare a vector of doubles named swimming logs with size of num students. Initialize first element to first student and last element to last student. Fill the middle elements with zeros.

Firstly, declare a vector of doubles named swimming logs with a size of num students. This is done by writing "vector swimming logs(num students);". This creates a vector with the size specified by num students, which can be read from input.

Next, initialize the first element of the vector to first student. This is done by writing "swimming logs[0] = first student;". This sets the first element of the vector to the value of first student, which can be read from input.

Then, initialize the last element of the vector to last student. This is done by writing "swimming logs[num students - 1] = last student;". This sets the last element of the vector to the value of last student, which can be read from input.

Finally, fill the middle elements of the vector with zeros. This is done by writing "for (int i = 1; i < num students - 1; i++) { swimming logs[i] = 0; }". This loop iterates from the second element to the second last element of the vector, setting each element to 0. This completes the initialization of swimming logs with the specified values.
