Zohar is using scissors to cut a rectangle with a length of 5x – 2 and a width of 3x + 1 out of a larger piece of paper. The per

imeter of the rectangle is 2(5x – 2) + 2(3x + 1). If x = 4 centimeters, what is the total distance Zohar needs to cut with the scissors? 31 centimeters 36 centimeters 62 centimeters 70 centimeters

They give you the equation: 2(5x-2)+2(3x+1)

and they give you x. x=4

just substitute and solve: 2((5•4)-2)+2((3•4)+1)=2(20-2)+2(12+1)=2(18)+2(13)=36+26=62

A satellite dish is the shape of a paraboloid. The dish is 38 inches wide, and 10 inches deep. How many inches should the receiv
vitfil [10]

Answer:

9 in approx

Step-by-step explanation:

Step one:

given data

the shape of the satellite dish takes the form of a paraboloid.

the diameter of the dish is 38in wide

and 10 inches deep.

step two:

The expression for the paraboloid is

4ay=x^2

where y is the vertical axis of the  paraboloid

a is vertex to focus.

and x is the radius of the dish

x= 38/2= 19in

substituting we have

4a10 =19^2\\\\40a=361 \\\\

divide both sides by 40

a=361/40\\\\a=9.025

vertex to focus= 9 in approx

Which expression can be simplified to find the slope of the trend line in the scatterplot?
Maslowich

Answer:

1. \frac{24-79}{12-2}

Step-by-step explanation:

We have been given a graph of a scatter-plot and we are asked to find the correct expression than can be solved to find the slope of the trend line in the scatter-plot.

Since we know that slope of a line can be found by dividing the difference of the y-coordinates of 2 points on a line by difference of the x-coordinates of these same points.  

\text{Slope}=\frac{y_2-y_1}{x_2-x_1}  

We can see that (2,79) and (12,24) are two given points of our trend line. So let us substitute x and y-coordinates of our given points in slope formula to find the our desired expression.    

x_1=2

x_2=12

y_1=79

y_2=24

\text{Slope}=\frac{24-79}{12-2}

Therefore, the expression \text{Slope}=\frac{24-79}{12-2} can be solved to find the slope of the trend line in the scatter-plot and 1st option is the correct choice.

1. If x=3-√3,<br> prove that x²<br> +36<br> x²<br> = x²
valentina_108 [34]

Answer:

we get x^2=12-6\sqrt{3}

Step-by-step explanation:

We are given: x=3-\sqrt{3}

We need to find x^2

Note: Since question is not clear, I am assuming that we need to find x^2

Solving:

x=3-\sqrt{3} \\Taking \ square \ on \ both \ sides\\x^2=(3-\sqrt{3})^2\\

We know that (a-b)^2= a^2-2ab+b^2

Using formula and simplifying

x^2=(3)^2-2(3)(\sqrt{3})+(\sqrt{3})^2\\x^2=9-6\sqrt{3} +3\\x^2=12-6\sqrt{3} \\

So, we get x^2=12-6\sqrt{3}
