First, you need to find the trend line that you are going to use before you can answer question 9 and 10. 

To do that select 2 points from your list and find the y = mx + b equation. 

After you have your equation, all you need to do is plug in the values that you are given for x. Evaluate the expression and you will have your answer.

point a has the coordinates(2,5) point B has the coordinates (6,17) how long is segment ab in simplified radical form
IRISSAK [1]

Answer:

4\sqrt{10}

Step-by-step explanation:

We have been given that point A has the coordinates(2,5) point B has the coordinates (6,17).

To find the length of segment AB we will use distance formula.

\text{Distance}=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Upon substituting coordinates of point A and point B in distance formula we will get,

\text{Distance between point A and point B}=\sqrt{(6-2)^2+(17-5)^2}

\text{Distance between point A and point B}=\sqrt{(4)^2+(12)^2}

\text{Distance between point A and point B}=\sqrt{16+144}

\text{Distance between point A and point B}=\sqrt{160}

\text{Distance between point A and point B}=4\sqrt{10}

Therefore, the length of segment AB is 4\sqrt{10}.

Solve for x.<br><br> 5/6 x = 10/3<br><br> x = 4/3<br><br> x = 2<br><br> x = 25/9<br><br> x = 4
SashulF [63]

Answer: LAST OPTION.

Step-by-step explanation:

In order to solve for the variable "x" from the expression \frac{5}{6}x=\frac{10}{3}, you need to follow these steps:

1) You need to multiply both sides of the equation by 3:

3(\frac{5}{6}x)=(\frac{10}{3})(3)\\\\\frac{15}{6}x=10

2)  You need to multiply both sides of the equation by 6:

(6)(\frac{15}{6}x)=(10)(6)\\\\15x=60

3) Finally, you can divide both sides of the equation by 15:

\frac{15x}{15}=\frac{60}{15}\\\\x=4

An archway is modeled by the equation y = -2x2 + 8x. A rod is to be placed across the archway at an angle defined by the equatio
Nata [24]
1) y= - 2x² + 8x. It's a parabola open downward (a<0)  
2) x - 2.23.y + 10.34 = 0 . Re-write it : y = (x/2.23) + (10.34/2.23), a linear equation.
To find the intersections between 1) & 2), let 1) = 2)
-2x² + 8x = (x/2.23) + (10.34/2.23) 
-2x² + 8x - (x/2.23) - (10.34/2.23) =0 ; solve this quadratic for x values:

x' (that is A) = 0.772 & x" (that is B) = 3. (these are the values of x-intercept (parabola with line). To calculate the y-values, plug x' & x' in the equation:
for x' = 0.772, y = 0.34 → B(0.772 , 0.34)
for x" = 3, y = 0.016     → A(3 , 0.O16)
So B IS AT 0.34 Unit from the ground

The ratio of the corresponding side lengths is 10:7 What is the ratio of the areas?
algol [13]
100 to 49. Because area is units squared, and it is finding by multiplying the side lengths, you would simply square the ratio.
