Answer:

Point on the line: (0, 15)

Slope: 3

Step-by-step explanation:

Step 1: Put the equation in slope-intercept form

    The slope-intercept form is written like this: y = mx + b

    m = slope

    b = y-intercept

    1. y = 3 + 3(x + 4) → y = 3x + 15

Step 2: Retrieve the values from the equation

    y-intercept = 15

    slope = 3

If the partial derivative is equal to zero for all values of x then it indicates that the function is constant.

What is a partial derivative?

In differential calculus, partial derivative is defined as the rate of change of multivariable functions concerning change in just one of its variables.

Consider the restriction of f to a line y=c,

then

[tex] \frac{∂f}{∂x}(x \: c) = fx(f \: c) = 0[/tex]

Pick 2 points a and b, then by mean value theorem there is x0, such that

[tex]fx(x \: c) = \frac{f(b \: c) - f(a \: c)}{b - a} = 0[/tex]

[tex]⟹f(b \: c) - f( \: a \: c) = 0⟹f(b \: c) = f(a \: c)⟹f(x \: c) = const.[/tex]

We can show the same way that f(c,y)=const.

Combining f(x,c)=const and f(c,y)=const to get f(x, y)=const.

Hence, If the partial derivative is equal to zero for all values of x then it indicates that the function is constant.

Step-by-step explanation:

constant of proportionality = 10/20 = 1/2

Variable, x, represents the independent variable and the dependent variable is the distance, because the distance depends on the time. A function relating these variables is R(x) = 60x. So R(3) = 180 miles, meaning after 3, a distance of 180 miles was covered.

The dependent variable is the outcome or result that is being measured or observed, while the independent variable is the factor that is manipulated or changed to see its effect on the dependent variable.

Therefore, we can say that: the independent variable, x, represents the time and the dependent variable is the distance, because the distance depends on the time.

A function relating these variables is R(x) = 60x, representing the distance covered as a function of time at a constant speed of 60 miles per hour.

So, R(3) = 60 * 3 = 180 miles, meaning after 3 hours of driving, Hannah will have covered a distance of 180 miles.

The independent variable x represents time in hours and the dependent variable R(x) represents distance in miles. The relationship between these variables is expressed by the function R(x) = 60x, signifying the distance (in miles) Hannah would have driven after x hours. For instance, R(3) equals 180, implying that after 3 hours, Hannah would have driven 180 miles.

In this context, the independent variable, x, represents the time in hours and the dependent variable, R(x), is the distance in miles, because the distance depends on the time. A function relating these variables is R(x) = 60x. This is because Hannah's speed is 60 miles per hour, so the formula for distance (Rate x Time) becomes 60 times the number of hours (x). So R(3) equals 180, meaning after 3 hours, Hannah would have driven 180 miles.

A triangle is a polygon with three vertices and three sides.

The angles of the triangle are formed by the connection of the three sides end to end at a point.

The triangle's three angles add up to 180 degrees in total.

So, knowing that the third side of a triangle must be longer than the sum of the first two sides and shorter than the difference between the first two sides allows us to obtain:

x > (9-6) so x > 3 and x < (9+6) so x < 15

 The height of the top change when the lower end is feet from the wall by -4.5 ft/sec.

Given,

Assume that the horizontal floor is x and the vertical wall is y in distance (6 ft).

This creates a triangle, with the ladder serving as the 10 foot hypotenuse.

dy/dt = 6 feet per second.

Pythagoras' law states that there is a link between x and y.

(x²) + (y²) = (hypothenus²) = 10².

When both sides of the equation are distinct,

0 = 2x(dx/dt) + 2y(dy/dt)

(x/y) × (dx/dt) = dy/dt

y = √(10²) - (6²) = 8ft

Consequently, dy/dt = (6/8) × (6/1)= -4.5 ft/sec.

F(-2, -2, 2)  =   -2j +2i

F(-2, 2, -2) =  -2j -2i

The width of the river is 1700m

What is the time, distance & speed relation?

Speed is calculated by dividing the distance traveled by the amount of time it took to get there. Divide the distance by the speed to find the passing time. To get the distance, multiply the speed by time.

Let 'x' be the distance from THE far bank where 700 is the distance to the NEAR bank

boat one has travelled 700 (rate = 700/unit time) boat two has travelled   x rate = x / unit time

boat one then travels   x  + 400  more      and boat two travels   700 + (700+x -400) more    when they meet

The time is the same:    

rate x time = distance  

distance/rate = time    

equate the distances divided by the respective rates

(700 + x + 400)/700     =    (  x  +  700     +  (700+x-400) )/x

1100x + x^2 = 1400x + 700000

x^2 - 300x - 700000 = 0                        

quadratic formula yields  x = 1000  

One boat travels 700 the other 1000 when they first meet.....width of the river =   700+ 1000 = 1700 m

Hence, the width of the river is 1700m

"The scatter plot shows a linear association."  

What is scatter plot ?

Several dots are plotted on horizontal and vertical axes to form a scatter plot. In statistics, scatter plots are crucial because they can demonstrate the degree of correlation, if any, between the values of observed quantities or occurrences (called variables).

But how?  Well, linear means: "arranged in or extending along a straight or nearly straight line." Which if you didn't notice.. All the points on the graph, make up a generally straight line.

"No association" means there is no line or association with any of the points.  So, you'd pick that if the points were all over the graph in no order, line or combination; which isn't the case.  

"Negative association" is when the top of the points come from the left of the graph lowering into the right. While Positive association would be from right to left.  So, it couldn't be choice "Negative Association" since it's coming from right to the left of the graph.

"The point  (2, 14) is an outlier."  If you didn't know, an outlier is one dot out of a whole group.  Think of it as if EVERYONE was wearing pink except one; who wore black.  It's just the out of placed kind of dot; but it's supposed to be there.  When you look at the graph, there is no dot or outlier at point (2,14) so, that's automatically out as well.

Probability is that the branch of arithmetic regarding numerical descriptions of however possible an occasion is to occur, or however possible it's that a proposition is true.

Main body:

Two dice are thrown  S = { (i,j) / i, j =1:6}

a) X : Number observed from the fair die.

   Y : Number observed from the unfair die.

   P(X=1, Y=1) = 1/6 * 1/9 =1/54  

Similarly we can obtained remaining probabilities.

P(X=2, Y=2 ) = 1/6 * 1/9 =1/54    

P(X=3, Y=3 ) = 1/6 * 1/9 =1/54

P(X=4, Y=4 ) = 1/6 * 1/9 =1/54

P(X=5, Y=5 ) = 1/6 * 3/9 =3/54 = 1/18

P(X=6, Y=6 ) = 1/6 * 2/9 =2/54 = 1/27

the joint distribution of X and Y is  =

⇒P(X=1, Y=1) = 1/6 * 1/9 =1/54  + P(X=2,  Y=2 )+ P(X=3, Y=3 ) +  P(X=4, Y=4)+

The squirrel was at its highest point when, v=0, which occurred 2.25 seconds after it jumped.

Squirrel reaches the ground in 5.5 seconds.

What is the relation between height and velocity?

We can find velocity if equation of height is given by differentiating the equation with respect to time.

According to the given question:

The squirrel can only have reached its maximum height when its velocity equals zero.

If h=-2t^2+9t-11

Then dh/dT=v=-4t+9

A) Therefore ,at the maximum height, the velocity ,v=0.

That is, 4t=9 , consequently, t=2.25s

Therefore, when t=2.25s

h=-2(2.25)^2 + 9(2.25)-11

The maximum height reached is then h=21.125ft

B) As explained above, the squirrel was at its highest point when, v=0, which occurred 2.25seconds after it jumped.

C) The squirrel reaches the ground when h=0...

0=-2t^2+9t+11

-2t^2-2t+11t+11=0

-2t(t+1)+11(t+1)=0

(-2t+11)(t+1)=0, since t>0 for this problem...
