Using displacement as a vector quantity, the change or displacement of the car is 3 blocks

Distance is the total movement of an object without any regard to direction. We can define distance as to how much ground an object has covered despite its starting or ending point.  is a vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position. Distance and displacement are two quantities that seem to mean the same but are distinctly different with different meanings and definitions. Distance is the measure of “how much ground an object has covered during its motion” while displacement refers to the measure of “how far out of place is an object.”

The displacement of the car will the change in it's position from starting to it's present position.

This can be calculated mathematically as

2 + 3 - 2 = 5 - 2 = 3

The displacement is 3 blocks.

Answer:

[tex] \displaystyle{y' = \dfrac{ - 3x( {x}^{3} + 6) }{( {x}^{3} + 3)^{2} }}[/tex]

Step-by-step explanation:

We can use the quotient rule:

[tex] \displaystyle{y = \frac{u}{v} \to y '= \dfrac{u'v - uv'}{ {v}^{2} }}[/tex]

In this case, u and v both are functions. By applying formula above, we will have:

[tex] \displaystyle{y' = \dfrac{(3 {x}^{2})' ( {x}^{3} + 3) - (3 {x}^{2} )( {x}^{3} + 3)' }{( {x}^{3} + 3)^{2} }}[/tex]

Then apply power rule to derive functions, we have to know that:

[tex] \displaystyle{y = {x}^{n} \to y' = n {x}^{n - 1} } \\ \\ \displaystyle{y = c \to y' = 0 \: \: \: (c \in \mathbb{R})}[/tex]

Therefore, we will have:

[tex] \displaystyle{y' = \dfrac{6x ( {x}^{3} + 3) - (3 {x}^{2} )3 {x}^{2} }{( {x}^{3} + 3)^{2} }}[/tex]

Expand the terms in:

[tex] \displaystyle{y' = \dfrac{6 {x}^{4} + 18x - 9 {x}^{4} }{( {x}^{3} + 3)^{2} }} \\ \\ \displaystyle{y' = \dfrac{ - 3 {x}^{4} + 18x }{( {x}^{3} + 3)^{2} }} \\ \\ \displaystyle{y' = \dfrac{ - 3x( {x}^{3} + 6) }{( {x}^{3} + 3)^{2} }}[/tex]

The probability that an athlete used steroids, given that they tested positive, is approximately 0.5025%.

In order to calculate the probability that an athlete used steroids given the information provided, we need to know the probability that they tested positive. To do this, we can use the formula for conditional probability:

P(A|B) = P(A and B) / P(B)

In this case, we are trying to find the probability that an athlete used steroids (A) given that they tested positive (B). We know that the probability of A is 1% and the probability of B is 0.5%, so we can calculate P(A and B) by multiplying these two probabilities together:

P(A and B) = 1% * 0.5% = 0.005%

Next, we need to calculate P(B), which is the probability that the athlete tested positive. Since we know the false positive rate and the true positive rate of the test, we can use these to calculate P(B) using the formula:

P(B) = P(A and B) + P(not A and B)

P(B) = P(A|B) * P(B) + P(not A|B) * P(B)

P(B) = 0.99 * 0.005% + 0.005 * (1 - 0.005%)

P(B) = 0.00495% + 0.005 * 0.999

P(B) = 0.0099495%

Now that we have P(A and B) and P(B), we can plug these values into the formula for conditional probability to calculate the probability that an athlete used steroids, given that they tested positive:

P(A|B) = P(A and B) / P(B)

P(A|B) = 0.005% / 0.0099495%

P(A|B) = 0.5025%

Step-by-step explanation:

In equations, you need to get the variable on one side and the answer on the other. In this instance, you divide both sides by 5.24 so you're left with w = 3.15.

Hope this helps, have an amazing day!

Answer:

d) 3.15

Step-by-step explanation:

Given equation,

Point slope form of the new line would be

(y -2) = m (x-3)      from the given formula

From the GIVEN line....its slope, m , is 1/2

      perpendicular slope is  - 1/m = -2    ( this is something you have to remember/learn)

then the NEW Line becomes

(y-2) = -2 ( x-3)       expand and simplify

y-2 = -2x+ 6

y = -2x + 8      Done !

Answer:

y = - 2x + 8

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = [tex]\frac{1}{2}[/tex] x - 9 ← is in slope- intercept form

with slope m = [tex]\frac{1}{2}[/tex]

given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{1}{2} }[/tex] = - 2 , then

y = - 2x + c ← is the partial equation

to find c substitute the point (3, 2 ) into the partial equation

2 = - 2(3) + c = - 6 + c ( add 6 to both sides )

8 = c

y = - 2x + 8 ← equation of perpendicular line

The four fundamental operations of arithmetic are addition, subtraction, multiplication, and division of two or more quantities. Included in them is the study of numbers, especially the order of operations, which is important for all other areas of mathematics, including algebra, data management, and geometry. The rules of arithmetic operations are required in order to answer the problem.

Let the Bethan's income be x

Amrit's income is 32% more than Bethan's income.

So, Amrit's income=x+32%

Amrit and Bethan's combined income is £54868.

According to given question we have

x+x+32%=£54868

2x+32/100=£54868

2x=54868-0.32

2x=54867.68

x=27433.84

Bethan's income=£ 27433.84

Amrit's income

=x+32%

What is an angle of a triangle?

An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices, respectively. Angles created by two rays are in the plane where the rays are located. The meeting of two planes also creates angles. We refer to these as dihedral angles.

Given that ∠JKI = (5x−3)⁰, ∠KIJ=(2x+8)⁰, and ∠IJK=(x−1)⁰.

The sum of all angles of a triangle is 180⁰.

(5x−3)⁰ + (2x+8)⁰ + (x−1)⁰ = 180⁰

(5x + 2x + x) + ( - 3 + 8 -1) = 180

8x + 4 = 180

Subtract 4 from both sides:

8x = 176

x = 22

Putting x = 22 in ∠JKI = (5x−3)⁰:

∠JKI = (5×22 − 3)⁰

It is given that, Lucia draws a square and plots the center of the square.

Lucia claims that " any rotation about the center of the square that is a multiple of 45° will carry the square onto itself".

To verify this claim, we need to construct a square (ABCD) as shown in the figure.

When the square ABCD is rotated about 45° where we can it is 1 × 45°, the square formed is A'B'C'D' is not the same as the actual one. So, they are not in symmetry after the rotation n this case.

If we rotate again, that is for the second multiple of 45° (2 × 45°), we get a square A''B''C''D''. But, now the square is similar to the actual one. So, they are in symmetry.

It is given to us that -

If the price of admission was $17, the attendance was about 1150 customers per day

When the price of admission was dropped to $12, attendance increased to about 1250 per day

We have to write a write a linear equation for the attendance in terms of the price.

Let us say that -

Price of admission is given as "p"

and, attendance of customers is given as "q"

It is given to u that -

For p = $17, q = 1150 customers per day

For p = $12, q = 1250 customers per day

We know that the point-slope form of a linear equation can be represented as -

m = slope of the linear equation = [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex] ----- (2)

From the given information, we can represent the points as -

([tex]x_{1} ,y_{1}[/tex]) = (17, 1150)

and, ([tex]x_{2} ,y_{2}[/tex]) = (12, 1250)

Substituting the values of ([tex]x_{1} ,y_{1}[/tex]) and ([tex]x_{2} ,y_{2}[/tex]) in equation (2), we have -

[tex]m = \frac{y_{2} -y_{1} }{x_{2} -x_{1} }\\= > m = \frac{1250-1150}{12-17}\\= > m = \frac{100}{-5} \\= > m = -20[/tex]------ (3)

Now, substituting the values of ([tex]x_{1} ,y_{1}[/tex]) and m from equation (3) in the point-slope form of the linear equation (1), we have

[tex]y-y_{1} =m(x-x_{1} )\\= > y-1150=(-20)(x-17)\\= > y-1150=-20x+340\\= > y=-20x+340+1150\\= > y=-20x+1490[/tex]

In terms of price, p we can write the above linear equation as -

So, to find the number of miles of land being displayed on the map, you would do the following calculation: 12 inches * (200 miles / 2 inches) = 600 miles.

Answer:4.50t + 6.75b = 576

Step-by-step explanation:

Well said. I 100% know what this is.

The equation is y = 2.5. And the actual distance in the third case and the distance on the map in the fourth case will be 120 miles and 90 mm, respectively.

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

Let 'x' be the distance on the map and 'y' be the actual distance. Then the equation of the line is given as,

(y - 25) = [(50 - 25) / (20 - 10)](x - 10)

y - 25 = 2.5x - 25

y = 2.5x

If x = 48 mm, then the actual distance is given as,

y = 2.5(48)

y = 120 miles

If y = 225 miles, then the distance on the map is given as,

225 = 2.5x

x = 90 mm
