Perimeter of the room left after removing the corner, using the Pythagoras theorem = 76ft.

According to the Pythagoras theorem, the square of the hypotenuse of a right-angled triangle is equal to the sum of the squares of the other two sides. Imagine that BC² = AB² + AC² exists in the ABC triangle.

In this equation, AB stands for the base, AC for the altitude, and BC for the hypotenuse. It should be remembered that a right-angled triangle's hypotenuse is its longest side.

Now here, sides of the rectangle are, l = 22ft and b = 19ft.

A right triangle is removed from the corner.

The dimension of the triangle becomes height =12ft and base = 9ft.

As it's a right triangle, the hypotenuse using the Pythagoras theorem =

√ (12² + 9²)

=√ 225

= 15ft.

Now, the perimeter of the shape left after removing the triangle =

22ft + 19ft + 10ft + 15ft + 10ft

= 76ft.

Therefore, the perimeter of the room =76feet.

Step-by-step explanation:

This is the same as y = 2.5x+10 since 5/2 = 2.5

============================================

Explanation:

Let's find the slope of the line through those given points

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

m = (7-3)/(-9-1)

m = 4/(-10)

m = -2/5

To find the perpendicular slope, we flip the fraction and flip the sign

flip the fraction: -2/5 turns into -5/2

flip the sign: -5/2 turns into 5/2

The perpendicular slope is 5/2

Side note: The original slope (-2/5) and the perpendicular slope (5/2) multiply to -1.

-------------------------

Now find the midpoint

We add the x coordinates of the original points to get 1+(-9) = -8, which cuts in half to -8/2 = -4. This is the x coordinate of the midpoint.

Do the same for the y coordinates. First add: 3+7 = 10, then cut in half: 10/2 = 5. The y coordinate of the midpoint is 5.

The midpoint is (-4,5)

-------------------------

The perpendicular bisector will go through this midpoint. It has a slope of m = 5/2

Turn to point slope form to find the equation we need

y - y1 = m(x - x1)

y - 5 = (5/2)(x - (-4))

y - 5 = (5/2)(x + 4)

y - 5 = (5/2)x + (5/2)*4

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

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

y = (5/2)x + 15

y = 2.5x + 15 ... since 5/2 = 2.5

True. In game theory and decision theory, the Hurwicz criterion is a decision-making rule between the minimax and maximin criteria.

The Hurwicz criterion is a hybrid of the minimax and maximin criterion. The minimax criterion is concerned with minimising the most potential loss, whereas the maximin criterion is concerned with maximising the least possible gain. The Hurwicz criterion is expressed as a weighted average of the greatest and worst outcomes:

Decision value = α(best payoff) + (1-α)(worst payoff)

where alpha is coefficient representing the decision-maker's optimism or pessimism. The Hurwicz criterion provides a more versatile decision-making tool than the minimax or maximin criteria alone, allowing for a balance between risk-taking and risk-aversion.

The number of moles of Cu2+ in the 16.0 g sample of the soluble plant fertilizer can be calculated as follows:

First, we need to determine the mass of Cu2+ in the sample. Since the concentration of Cu2+ in the fertilizer is given as a percentage by weight, we can simply multiply the mass of the sample by the concentration to obtain the mass of Cu2+ in the sample:

Mass of Cu2+ = 16.0 g x 0.0700% = 0.0112 g

Next, we need to convert the mass of Cu2+ to moles. The molar mass of Cu2+ is 63.55 g/mol. Therefore, the number of moles of Cu2+ in the sample is:

Moles of Cu2+ = Mass of Cu2+ / Molar mass of Cu2+ = 0.0112 g / 63.55 g/mol = 0.0001767 mol

Thus, the number of moles of Cu2+ in the 16.0 g sample of the soluble plant fertilizer is 0.0001767 mol.

Answer:

y=2/3x-11/3

Step-by-step explanation:

Hi there!

We are given the equation 2x-3y=9 and we want to write an equation that is parallel to it and that passes through (4,-1)

Parallel lines have the same slopes

So we need to first find the slope of 2x-3y=9

We can do this by converting the equation of the line from standard form (ax+by=c where a, b, and c are integers) to slope-intercept form (y=mx+b, where m is the slope and b is the y intercept)

To do this, we need to isolate y on one side

2x-3y=9

subtract 2x from both sides

-3y=-2x+9

divide both sides by -3

y=2/3x-3

as 2/3 is in the place where m is, 2/3 is the slope of the line

It's also the slope of the line parallel to it that passes through (4,-1).

Here's the equation of that line so far:

y=2/3x+b

now we need to find b

as the line will pass through the point (4,-1), we can  4 as x and -1 as y in order to solve for b

-1=2/3(4)+b

multiply

-1=8/3+b

subtract 8/3 to both sides

-11/3=b

Substitute -11/3 as b into the equation

y=2/3x-11/3

There's the equation

The distance measured from one end to the other of an object's longer or longest side. additionally: any measured distance. the state or trait of being long. the duration of something duration of a visit. The length of something is defined as its measurement or extent from end to end. In other terms, it is the biggest of two or the highest of three geometrical forms or objects' dimensions.

Given,

x=9t-3t³, y=9t²

The loop starts from x=0 and with x=0

Therefore, x=0

9t-3t³=0

3t(3-t²)=0

3-t²=0

t=±√3

dx/dt=9-9t²

dy/dt=18t

Hence length of a loop of a curve,

By using the integration,

=\(\int\limits^a_b\)√(dx/dt)²+(dy/dt)²

Here a=√3, b= -√3

=\(\int\limits^a_b\)√(9-9t²)²+(18t)²dt

=\(\int\limits^a_b\)√(1-t²)²+4t²dt

=\(\int\limits^a_b\)√1-t⁴-2t²+4t²dt

=\(\int\limits^a_b\)√1+t⁴+2t²

=\(\int\limits^a_b\)√(1+t²)dt

=9(t+t²/3)

Therefore, each salary is followed by a 'K' which represents thousand.

Let’s begin by defining variables for each employee and start forming the equations which will help us to solve the system of linear equations.Let x1 be the salary of the first analyst.x2 be the salary of the second analyst.x3 be the salary of the third analyst.x4 be the salary of the first programmer.x5 be the salary of the second programmer.x6 be the salary of the salesperson.So we have, x1 + x2 + x3 = 264 ............(1)(The analysts are paid a combined total of $264K.)x3 = 0.5(x1 + x2) ...........................(2)(The third analyst makes 50% less than the first two analysts combined.)x1 = 1.2x2.........................................(3)(The first analyst makes 20% more than the second analyst.)x4 = x2 + 30.................................(4)(The first programmer makes $30K more than the second.)x5 = x4 - 20...................................(5)(The salesperson makes $20K less than the second programmer.)Adding all these equations, we get;x1 + x2 + 0.5(x1 + x2) + x2 + 1.2x2 + x2 + 30 + x4 - 20 = 5052.7x1 + 5.2x2 + x4 = 495............(6)Now using equations 1, 2 and 3;x1 + x2 + 0.5(x1 + x2) = 264

Substituting x3 from equation 2, we get;x1 + x2 + 0.5(x3) = 264Substituting the value of x3 from equation 2, we get;x1 + x2 + 0.5(x1 + x2) = 264x1 + x2 + 0.5x1 + 0.5x2 = 2641.5x1 + 1.5x2 = 264Substituting the value of x1 from equation 3;x1 = 1.2x21.2x2 + x2 + 0.5(1.2x2 + x2) = 2642.9x2 = 264x2 = 91.72Putting the value of x2 in equation 3x1 = 1.2(91.72)x1 = 110.06Putting the value of x2 in equation 4x4 = 91.72 + 30x4 = 121.72Putting the value of x2 in equation 5x5 = 91.72 - 20x5 = 71.72

Therefore, the salary (in $K) of each employee is:First analyst: x1 = 110.06 KSecond analyst: x2 = 91.72 KThird analyst: x3 = 101.89 KFirst programmer: x4 = 121.72 KSecond programmer: x5 = 71.72 KSalesperson: x6 = 66.89 K (x6 is found by subtracting total salaries of the other employees from total salary)Note: The salaries are in thousands.

Step-by-step explanation:

The slope of a velocity graph represents the acceleration of the object.

Why does slope make things go faster?

Gravity is what causes the change in speed on a slope. Objects accelerate (move faster) when traveling downhill, and decelerate (move slower) when moving uphill (slow down).

                       They will then continue moving at the same pace on a level surface, presuming there is little friction.

=  area of graph is 1/2 t₀a₀.

=  area is less than  1/2 t₀a₀.

= area is more than 1/2 t₀a₀.
