The new price of the purchase after the 13% discount can also be expressed as 0.87x.

The new price of the purchase after the 13% discount is expressed as x - 0.13x.

We can factor out x as follows to simplify this expression by combining like terms:

x - 0.13x = x(1 - 0.13) (1 - 0.13).

We can simplify the expression in parentheses as follows:

1 - 0.13 = 0.87.

So, by combining like terms, the equivalent expression is:

x - 0.13x = 0.87x.

As a result, the new purchase price after the 13% discount can also be expressed as 0.87x.

Answer:

[tex]\textsf{C)} \quad \dfrac{23}{60}[/tex]

Step-by-step explanation:

The odd number outcomes are 1, 3 and 5.

The probability for rolling each of the odd numbers is the frequency of the outcome divided by the total number of rolls.

[tex]\implies \sf P(x=1)=\dfrac{8}{60}[/tex]

[tex]\implies \sf P(x=3)=\dfrac{6}{60}[/tex]

[tex]\implies \sf P(x=5)=\dfrac{9}{60}[/tex]

Therefore, the experimental probability that the number rolled was odd is:

[tex]\begin{aligned}\sf P(x\;is\;odd)&=\sf P(x=1)\;or\;P(x=3)\;or\;P(x=5)\\\\&=\sf \dfrac{8}{60}+\dfrac{6}{60}+\dfrac{9}{60}\\\\&=\sf \dfrac{8+6+9}{60}\\\\&=\sf \dfrac{23}{60}\end{aligned}[/tex]

The electric potential at the center of the circle formed by the plastic rod is -1.644V.

We know that the formula to find the electric potential V = KQ/R,

where K is Coulombs constant, Q is the charge, and R is the radius of the circle.  

According to the question,

The radius of the circle formed by the plastic rod on bending = 8.20 cm

(Converting cm to m by dividing by 100)               = (8.20)/100 = 0.082m

We know that Coulombs constant (K) =  8.99 × 10 ^ 9 N m^2/C^2

It is given that along one quarter of its circumference (Q1) =  +3.00 pC

and along the remaining circumference, the charge (Q2) = -6Q1

Therefore, electric potential (V) = K (Q1+KQ2) /R

= (8.99 × 10 ^ 9) (Q1 + (-6Q1)) / 0.082 = (8.99 × 10 ^ 9) (-5Q1)/ 0.082

= -5 (8.99 × 10 ^ 9) (3 X 10 ^ -12) / (0.082) = -1.644512V ≈ -1.644V

The formula to calculate the magic number in MLB is: Magic number = 163 - (number of wins by leading team) + (number of losses by trailing team) - 1.

The "magic number" in Major League Baseball (MLB) represents the combination of wins by the leading team and losses by the trailing team required for the leading team to clinch a playoff spot. To calculate the magic number, follow these steps:

1. Determine the total number of games in the season. In MLB, this is typically 162 games.

2. Subtract the number of games in the season from 163. For example, 163 - 162 = 1.

3. Subtract the number of wins by the leading team from 163. For example, if the leading team has 90 wins, 163 - 90 = 73.

4. Add the result from step 2 to the result from step 3. For example, 73 + 1 = 74.

5. Finally, subtract the number of losses by the trailing team from the result of step 4. For example, if the trailing team has 80 losses, 74 - 80 = -6. In this case, the magic number is zero, meaning that the leading team has already clinched a playoff spot.

Answer:

v = 1.165

Step-by-step explanation:

To find the value of v in the equation 0.4 = 0.167 + 0.2v, we can isolate v by subtracting 0.167 from both sides:0.4 - 0.167 = 0.2v0.233 = 0.2vNext, we can divide both sides by 0.2 to find the value of v:0.233 / 0.2 = 0.2v / 0.2v = 0.233 / 0.2v = 1.165So the value of v is 1.165.In conclusion, by subtracting 0.167 from both sides of the equation and dividing both sides by 0.2, we found that the value of v is 1.165.

Answer: The value of v that satisfies the equation 0.4 = 0.167 + 0.2v is 1.165.

Step-by-step explanation:

To find the value of v in the equation 0.4 = 0.167 + 0.2v, we can isolate v by subtracting 0.167 from both sides:

0.4 - 0.167 = 0.2v

0.233 = 0.2v

Next, we can divide both sides by 0.2 to solve for v:

0.233 / 0.2 = 0.2v / 0.2

v = 1.165

So, the value of v that satisfies the equation 0.4 = 0.167 + 0.2v is 1.165.

An equation of the line that satisfies the given conditions is x = 2y + 13.

To find the equation of the line that passes through the point (-9, -11) and is perpendicular to the line passing through (-6, 1) and (-2, -1), we can use the slope-point form of a line.

First, we find the slope of the line passing through (-6, 1) and (-2, -1). The slope of this line can be found using the formula:

m = (y2 - y1) / (x2 - x1)

where (x1, y1) and (x2, y2) are the coordinates of the two points.

Plugging in the values, we have:

m = (-1 - 1) / (-2 - (-6)) = -2 / 4 = -1/2

The slope of a line perpendicular to this line has a negative reciprocal, so the slope of the line through (-9, -11) that is perpendicular to this line is 1/2.

Next, we use the point-slope form of a line to find the equation of the line:

y - y1 = m (x - x1)

where (x1, y1) is a point on the line and m is the slope.

Plugging in the values, we have:

y - (-11) = 1/2 (x - (-9))

Expanding and simplifying, we get:

y + 11 = 1/2 (x + 9)

Multiplying both sides by 2, we get:

2y + 22 = x + 9

Subtracting 9 from both sides, we get:

2y + 13 = x

So, the equation of the line that satisfies the given conditions is:

x = 2y + 13

Step-by-step explanation:

Answer:

Step-by-step explanation:

The first step is to find the slope of the tangent line. To do that, we need to find the derivative of f(x):

f(x) = sin(x) + 2cos(x)

f'(x) = cos(x) - 2sin(x)

Now we can find the slope of the tangent line at x=0 by plugging in x=0 into f'(x):

f'(0) = cos(0) - 2sin(0) = 1

Therefore, the slope of the tangent line at x=0 is 1.

Next, we need to find the y-coordinate of the point on the graph where x=0. To do that, we simply plug in x=0 into f(x):

f(0) = sin(0) + 2cos(0) = 2

Therefore, the point on the graph where x=0 is (0, 2).

Now we can use the point-slope form of the equation of a line to find the equation of the tangent line:

y - y1 = m(x - x1)

where m is the slope and (x1, y1) is the point on the line. Plugging in m=1 and (x1, y1) = (0, 2), we get:

y - 2 = 1(x - 0)

Simplifying, we get:

y = x + 2

Therefore, the equation of the tangent line is y = x + 2.

Answer:

The equation of the tangent line at x = 0 can be found by differentiating the function f(x) and using the point-slope form of a line.

The derivative of f(x) is f'(x) = cos(x) - 2sin(x). Substituting x = 0 into f'(x) gives f'(0) = cos(0) - 2sin(0) = 1 - 0 = 1.

Therefore, the equation of the tangent line is y = 1x + b, or y = x + b.

To find the value of b, we can plug in x = 0 and y = f(0) = sin(0) + 2cos(0) = 2 into the equation. Solving for b, we get 2 = 0 + b, so b = 2.

Therefore, the slope-intercept equation of the line tangent to the graph of y = f(x) at the point (0,2) is y = x + 2.

The first part of the summary will simply list the current price of the house. This information is stored in the database and is retrieved by the program when it starts.

The next part of the summary will be the change in the house price since last month. This information is also stored in the database and is calculated by subtracting the price from last month from the current price.

Finally, the program will output the estimated monthly mortgage payment for the house. This is calculated by multiplying the current price of the house by 0.051 and then dividing the result by 12. This information is also stored in the database and is retrieved by the program when it starts.

So Ms. Shaw will completely fill 6 fish tanks and have 1 fish left.

Step-by-step explanation:

Ms. Shaw has 16 fish and each fish tank can hold 3 fish. To find out how many fish tanks she needs, we can divide the total number of fish by the capacity of each tank:

16 fish / 3 fish per tank ≈ 5.33 tanks

Since we cannot have a fraction of a tank, we need to round up to the nearest whole number. Therefore, Ms. Shaw needs 6 fish tanks to completely fill all her fish.

To find out how many fish are left, we need to subtract the number of fish in the full tanks from the total number of fish:

16 fish - (5 tanks * 3 fish per tank) = 1 fish left

So Ms. Shaw will completely fill 6 fish tanks and have 1 fish left.
