Answer: 17.09

Step-by-step explanation:

Given: The ordered pair that represents the vector from A(-9 9) to B(7 3).

The length of vector from points $(x_1,y_1)$ and $(x_2,y_2)$ is given by using distance formula:-

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Now, the length of vector AB is given by:-

$AB=\sqrt{(7-(-9))^2+(3-9)^2}\\\\=\sqrt{(7+9)^2+(-6)^2}\\\\=\sqrt{(16^2)+36} \\\\=\sqrt{256+36} \\\\=\sqrt{292}=17.0880074906\approx17.09$

Therefore, the magnitude of Ab = 17.09

Moving from a to b, the x component of the desired vector is 7-(-9) = 16, and
the y component is 3-9 = -6.

So the vector from a to b is <16,-6>, and the magnitude is

sqrt(16^2 + (-6)^2 ), applying the Pythagorean Theorem.

How to find the area of composite polygon that have a base of 16 meters height of 18 meters and a height of 11 meters.

LenaWriter [7]

The area of the composite polygon is:

$\boxed{A_{T}=376 \ m^2}$

<h2>Explanation:</h2><h2 />

Hello! remember you have to write complete questions in order to get good and exact answers. Here you haven't provided any figure, so I'll choose the figure below in order to illustrate this problem. A composite polygon is a polygon that can be divided into two or more basic shapes. So here we have a composite polygon formed by a triangle and a rectangle. So:

$A_{total}=A_{T} \\ \\ A_{triangle}=A_{tr} \\ \\ A_{rectangulo}=A_{r} \\ \\ \\ A_{tr}=\frac{b\times h}{2} \\ \\ b:Base \ of \ the \ triangle \\ \\ h:height \ of \ the \ triangle \\ \\ \\ A_{r}=B\times H \\ \\ B:base \ of \ the \ rectangle \\ \\ H:height \ of \ the \ rectangle$

So the area of the composite figure is:

$A_{T}=\frac{16\times 11}{2} + 16\times 18 \\ \\ A_{T}=88+288 \\ \\ \boxed{A_{T}=376 \ m^2}$

Find the slope and the y -intercept of the line.

Eduardwww [97]

Answer:

The slope is: 3

The y-intercept is: $\frac{2}{3}$ or $0.66$

Step-by-step explanation:

The equation of the line in Slope-Intercept form is:

$y=mx+b$

Where "m" is the slope of the line and "b" is the y-intercept.

To write the given equation in this form, we need to solve for "y":

$9x - 3y = -2\\\\- 3y = -9x-2\\\\y=3x+\frac{2}{3}$

Therefore, you can identify that the slope of this line is:

$m=3$

And the y-intercept is:

$b=\frac{2}{3}=0.66$

Jack is placing glass bottles into boxes to recycle. He can fit 12 bottles in each box.

djverab [1.8K]

His estimation is not reasonable because if you can only fit 12 bottles in a box and he has 10 boxes then he could only fit 120 out of the 200 bottles so he is short on boxes
