Answer:

The maximum of the parabola lands at (2,5).

The coordinates of the turning point of the parabola whose equation is y=-x²+4x+1 are (2, 5)

A coordinate system is a system that uses one or more numbers, or coordinates, to uniquely determine the position of the points.

The equation of Parabola is y=-x²+4x+1

The turning point (vertex) is the point where the derivative is equal to zero.

y=-x²+4x+1

Differentiate the equation

dy/dx=-2x+4

Now equate dy/dx with zero

dy/dx=0

-2x+4=0

-2x=-4

x=2

Now put x value in the equation

y=-(2)²+4(2)+1

y=-4+8+1

y=5

Hence the coordinates of the turning point of the parabola whose equation is y=-x²+4x+1 are (2, 5)

Confidence Interval =-0.76,+1.56

Step-by-step explanation:

The confidence interval can be determined by

(x1`- x2`) ± z∝/2 √s1²/n1 + s2²/n2

z∝/2 for 93% is 1.81

The mean and the standard deviations can be calculated using the calculator.

The mean x1`= ∑x/ n=  5+ 5+ 6+ 6+ 6+ 3+ 4+ 6+ 6+ 6

                                  = 53/10= 5.3

Standard deviation = s1`=   1.0049= 1.005

The mean x2`= ∑x/ n=  7+ 3+ 4 +7+ 4+ 7+ 3+ 3+ 7+ 4/10

                                  = 49/10= 4.9

Standard Deviation = s2= 1.75783= 1.76

Putting the values

(x1`- x2`) ± z∝/2   √s1²/n1 + s2²/n2

(5.3-4.9 ) ± 1.81 √1.005²/10 +1.76²/10

0.4 ± 1.81 √ 1.010025/10 + 3.0976/10

-0.76,+1.56

The confidence interval for 93% two tailed test is [-0.76,+1.56]

Answer:

Step-by-step explanation:

You want the solution to the system of equations ...

We notice that each of these equations has a leading minus sign, and has coefficients that have a common factor. We can multiply by -1 to make the leading coefficient positive, and we can divide by the common factor. Doing this puts the equations in standard form:

  2x -y = -6

  x -y = -4

Subtracting the second equation from the first gives ...

  (2x -y) -(x -y) = (-6) -(-4)

  x = -2

Rearranging the second equation to find y, we have ...

  y = x +4

  y = -2 +4 = 2

The solution is (x, y) = (-2, 2).

D. social security: 6621.60, Medicare: 1812.50

Step-by-step explanation:

Social security tax: 106800 x .062=6621.60

medicare tax: 125000 x .0145=1812.50

The Social Security tax is $6,621.60 and  Medicare tax is $1,812.50.

The given parameters:

This is a tax levied on both employers and employees to fund the Social Security programs.

The social security tax on the given earnings is calculated as follows;

Social security tax = 0.062 x 106,800 = $6,621.6

Medicare tax = 0.0145 x 125,000 = $1,812.5

Thus, the Social Security tax is $6,621.60 and  Medicare tax is $1,812.50.

Answer:

Step-by-step explanation:

If the overall area of the square is 30 units with a width of 6 units, all you need to do is divide 30 by 6. Or, if you add 6 till you get 30, which is much simpler.

If we start from six and count up till we get to/close to 30 without passing the number, we can do this.

6, 12, 18, 24, 30

Right on the dot of thirty! How lucky! Now we notice that while counting up, there were 5 variables (Don't know if I'm using this word correctly :\) of thirty in total. Then, if you want to double check, multiply 5 by 6 to get thirty and show proof that your answer is correct!

Good job! You survived the maths!

Anyways, here's the answer: The missing length of the 30 unit square is 5.

Answer:

5 is its length, divide the given length to the total area to get your missing length

Whenever given an area and a length or a width either ONE of those, you always divide the given length. Why? Because the number you get from dividing will make sense! That number you got from dividing times the give length will equal your area! Which is why you divide your given length to your total area.

Step-by-step explanation:

The amount of time taken to print by 3 printers is 2¹/₂₈ hours.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that It takes 4³/₄ hours to print some letters when 7 printers are used.

The amount of time will be calculated as,

Time = ( 4³/₄ x 3 )  ÷ 7

Time = (19 / 4 x 3 )  ÷ 7

Time =  57 / 28

Time = 2¹/₂₈ hours

Ed's answer of [tex]\frac{3}{8}[/tex] is correct because he divided [tex]\frac{1}{4}[/tex] by [tex]\frac{2}{3}[/tex] to get his answer.

Step-by-step explanation:

To solve for m in [tex]\frac{2}{3}m=\frac{1}{4}[/tex] you want to isolate m by dividing by [tex]\frac{2}{3}[/tex] on both sides, therefore he divided [tex]\frac{1}{4}[/tex] by [tex]\frac{2}{3}[/tex] to get his answer of [tex]\frac{3}{8}[/tex], and his answer is correct.

Rounded: $478.06

Step-by-step explanation:

Set up an equation:

Variable x = original price

62/100 = 296.40/x

Cross multiply

62 × x = 100 × 296.40

62x = 29,640

Divide both sides by 62:

x = 478.064516....

Round to nearest cent (hundredths place):

x = 478.06

Check your work (using the rounded estimate will be close to $296.40 but not exact because it is rounded; once you round your answer and it should match):
