Answer: In 2 seconds the car covered a distance of 55.56 meters.

Uniform rectilinear motion (also known as uniform linear motion or straight-line motion) is a type of motion in which an object moves along a straight line with a constant speed.

This means that the object's position changes by the same amount in a given period of time, regardless of the time that has elapsed. This type of motion is different from accelerated motion, in which the speed of an object changes over time. In uniform rectilinear motion, the speed of the object is constant, and the direction of motion does not change.

Data:

V = 100 km/h = 27.78 m/s

t = 2 s

d = ?

Since it asks us to calculate the distance in meters, we must convert from km/h to m/s.

        \(\boxed{\large\displaystyle\text{$\begin{gathered}\sf \bf{V=100 \ \frac{\not{km}}{\not{h}}*\left(\frac{1000 \ m}{1\not{km}}\right)*\left(\frac{1\not{h}}{3600 \ s}\right)= 27.78 \ m/s } \end{gathered}$} }\)

The uniform motion formula is: V=d/t

We clear for the distance, since it is the value that asks us to calculate.

\(\boxed{\large\displaystyle\text{$\begin{gathered}\sf \bf{V=\frac{d}{t} \iff \ d=v*t} \end{gathered}$}}\)

                          \(\boxed{\large\displaystyle\text{$\begin{gathered}\sf \bf{d=27.78 \ \frac{m}{\not{s}}*2\not{s} } \end{gathered}$}}\)

Answer:

The length of the diagonal is 11.879 units

Step-by-step explanation:

On any rectangle or square, any 2 adjacent sides and the diagonal that connects them makes a right triangle. The diagonal is the hypotenuse of that right triangle, and you can find it using the pythagorean theorem:

\(a^2+b^2=c^2\)

where a and b are the sides, and c is the diagonal.

\(\rightarrow8.4^2+8.4^2=c^2\\\rightarrow70.56+70.56=c^2\\\rightarrow c^2=141.12\\\rightarrow c\approx11.879\)

The graph represents the system of equations -3x + y = 3 and -x + 2y = -4 is option (b) On a coordinate plane, 2 lines intersect at (negative 2, negative 3).

The system of equation are

-3x + y = 3

-x + 2y = -4

Here we have to use the substitution method

-3x + y = 3

y = 3 + 3x

Substitute the value of y in the second equation

-x + 2(3 + 3x) = -4

-x + 6 + 6x = -4

-x + 6x = -4-6

5x = -10

x = -10/5

x = -2

Substitute the value of x in the first equation

-3x + y = 3

-3(-2) + y = 3

6 + y = 3

y = 3 - 6

y = -3

Hence, the graph represents the system of equations -3x + y = 3 and -x + 2y = -4 is option (b) On a coordinate plane, 2 lines intersect at (negative 2, negative 3).

The complete question is:

Which graph represents the system of equations –3x + y = 3 and –x + 2y = –4?

a) On a coordinate plane, 2 lines intersect at (3, 0).

b) On a coordinate plane, 2 lines intersect at (negative 2, negative 3).

c) On a coordinate plane, 2 lines intersect at (negative 1.5, 1).

The smallest sample size n that provides the desired accuracy is 10.

To find the smallest sample size n that provides the desired accuracy, we can use the formula:

n = (Z-value * standard deviation / margin of error)²

Where:
Z-value = the critical value for the desired confidence level (in this case, 1.96 for 95% confidence)
Standard deviation = the preliminary sample standard deviation (1.5 in this case)
Margin of error = the desired accuracy (0.3 units in this case)

Substituting the values, we get:

n = (1.96 * 1.5 / 0.3)²
n = 9.8

Since we cannot have a fractional sample size, we round up to the nearest whole number, giving us:

n = 10

Therefore, the smallest sample size n that provides the desired accuracy is 10.

Hey, there!

You just need is formula for slope (m) ok.

given that the points are A(9,3)) and B (-2,4).

Using formula for slope,

\(slope(m) = \frac{y2 - y1}{x2 - x1} \)

\(m = \frac{4 - 3}{ - 2 - 9} \)

\(or ,\: m = \frac{1}{ - 11} \)

Therefore, the slope of the points A(9,3) and B (-2,4) is (-1/11).

This is quite and easy one, but also vague at the same time.

A polygon is a shape with 5 or more sides, so, if she were drawing a pentagon, then the second polygon has to be an octagon. A pentagon has 5 sides, and an octagon has 5 + 3 sides

In the same vein, if she were drawing a hexagon, with 6 sides, the other polygon has to be monsoon, with 6 + 3 sides.

A heptagon also gives us a 7 + 3 polygon, in decagon.

All in all, it depends on the first polygon she's drawing as the question is vague in that aspect.

Answer:

PQ=17.088

Step-by-step explanation:

If M is the midpoint of PQ, then PM is half the length of PQ. So we cna find our answer by first finding PM.

Imagine a right angle triangle with PM as its hypotenuse. Since P(x,y)=(5,-15), and M(x,y)=(13,-18), we know that the length of the vertical side of this triangle is the difference between P and M's y (vertical) coordinates, and the length of the horizontal side of this triangle is the difference between P and M's x (horizontal) coordinates. This means the vertical side is equal to -15-(-18)=3 and the horizontal side is equal to 13-5=8. Since we know the lengths of the other two sides and PM is the hypotenuse, we can use pythagorus to find the length of PM:

PM = \(\sqrt{3^{2} +8^{2} } =\sqrt{9 +64 }=\sqrt{73} =\)8.544

Since PM is half PQ, PQ=2(8.544)=17.088

8 square unit to find the area of the parallelogram with vertices A(-4, 2), B(-2, 5), C(2, 3), and D(0, 0), follow these steps:

Step 1: Find the base and height vectors of the parallelogram. Let's use AB and AD as the base and height vectors, respectively.
AB = B - A = (-2 - (-4), 5 - 2) = (2, 3)
AD = D - A = (0 - (-4), 0 - 2) = (4, -2)

Step 2: Calculate the cross-product of the base and height vectors.
Cross product = AB_x * AD_y - AB_y * AD_x = (2 * -2) - (3 * 4) = -4 - 12 = -16

Step 3: Find the area by taking the absolute value of the cross product divided by 2.
Area = |Cross product| / 2 = |-16| / 2 = 8

Answer:

Hard to  see this....but

Midpoint of  AB =  [ (3 -5)/2,  (6 + 2) / 2  ]  =   [ -1, 4 ]  =  F

Midpoint of  of  BC  =  [ (-5 + 7)/2 , (2- 8)/2 ] =  [ 1 , -3]   =  D

Midpoint  of  AC   =   [ (3 + 7)/2 , ( 6 - 8)/2 ] =  [ 5, -1]  =  E

Slope of  CF =   [ -8 - 4 ]  / [ 7 - -1] =  -12/8 =  -3/2

Equation of  line  containing  CF =

y= -(3/2) ( x -  - 1)  + 4

y = -(3/2) ( x + 1)  + 4

y= (3/2)x - 3/2 + 4

y = -(3/2)x  +  5/2       (1)

Slope of AD  = [ 6 - -3 ] / [ 3 -  1] =  9/ 2

Equation of  line  containing AD  =

y = (9/2) (x -3) + 6

y =(9/2)x - 27/2  + 12/2

y= (9/2)x - 15/2      (2)

We  can  the  find  x intersection  of  medians  CF  and AD   by setting (1)  = (2)....so we have

-(3/2)x + 5/2 =  (9/2)x  - 15/2

10 = 6x

5 = 3x

x = 5/3

And using  (1)  the y value of the intersections is

y = -(3/2)(5/3) + 5/2  =  0

So....the intersection of the  medians  =  (5/3 ,  0)

We can check  this  by  writing an equation for  the  remaining median,  BE

Slope of line  containing  BE  =

[ 2 - -1 ]  / [ -5 - 5] =  3 / -10  =  -3/10

So the   equation of this line is

y = -(3/10)(x - - 5) + 2

y = - (3/10)x - 15/10  + 20/10

y= -(3/10)x +  5/10

y = -(3/10)x + 1/2

Note that when  x = (5/3)  we have that

y = -(3/10)(5/3) + 1/2

y =  - (5/10)  +  1/2

y=  -1/2 +  1/2  

y  =  0  

So.....this confirms that the  intersction of the  medians = ( 5/3, 0 )

Step-by-step explanation:

In the graph of the simple linear regression equation, the parameter ß1 is the slope of the true regression line.

The simple linear regression equation represents a linear relationship between a dependent variable and an independent variable. It can be written as y = ß0 + ß1x, where ß0 is the intercept and ß1 is the slope of the regression line.

The slope (ß1) determines the rate of change in the dependent variable (y) for each unit change in the independent variable (x). It represents the steepness or inclination of the regression line. The sign of ß1 indicates whether the line has a positive or negative slope, indicating the direction of the relationship between the variables.

Thus, in the context of the simple linear regression equation, the parameter ß1 is the slope of the true regression line.
