Answer:

Step-by-step explanation:

Mean is when you add all the numbers and divide by the number of items there are.

Example:

1,5,4,3,2

(So you first add 1+5+4+3+2=15. Then, divide by 5-which is the amount of numbers counted there- 15 divided by 5 and you get 3)

Foil: (x+9)(3x-4)

QveST [7]

QUESTION 1

The given binomial is;

$(x+9)(3x-4)$

First terms are multiplied: $x\times 3x=3x^2$

Outside terms are multiplied: $x\times -4=-4x$

Inside terms are multiplied: $9\times 3x=27x$

Last terms are Multiplied: $9\times -4=-36$

This gives us;

$=3x^2-4x+27x-36$

$=3x^2+23x-36$

QUESTION 2

We want to factor

$6r^5s+4r^4s^2-8r^2s$

The HCF is $2r^2s$

We factor to get;

$2r^2s(3r^3+2r^2s-4)$

QUESTION 3;

$x^2+x-2=0$

Split the middle term;

$x^2+2x-x-2=0$

Factor

$x(x+2)-1(x+2)=0$

$(x+2)(x-1)=0$

$(x+2)=0,(x-1)=0$

$x=-2,x=1$

The solutions are;

$x=-2$ and $x=1$

These are the x-intercepts of the graph of the function

$f(x)=x^2+x-2$

Please please help, need this done by 1:45!!!!

Answer:

option B. MB/AM=NC/AN

Step-by-step explanation:

we know that

The <u><em>Triangle Proportionality Theorem</em></u> states that if a line is parallel to one side of a triangle and it intersects the other two sides, then it divides those sides proportionally

In this problem

MN is parallel to BC

MN intersect AC and divide into AN and NC

MN intersect AB and divide into AM and MB

Applying the Triangle Proportionality Theorem

$\frac{AN}{NC}=\frac{AM}{MB}$

Rewrite

$\frac{MB}{AM}=\frac{NC}{AN}$

As a part of their weather unit, Anoki’s science class took a hot air balloon ride. As they passed over a fenced field, the angl

yulyashka [42]

Please refer to the figure attached for the diagram of this problem.

Steps needed to find the width of the field (CD):

First, we should note that angle d would be equal to 27 degrees because there are two parallel lines that are cut by a transversal. Furthermore, angle a would be equal to 5 degrees since we just need to subtract 27 from 32.

We then subtract 27 and 5 from 180 to get angle c. $180-27-5=148$ . Angle c is therefore 148 degrees.

Next, we need to find angle e which is just the supplementary of angle c. Angle e therefore measures $180-148=32$ degrees.

For the next step we use sine law to find the length of segment AC:
$\frac{sin(32)}{800} = \frac{sin(90)}{AC}$
$AC=1509.66$

Lastly, we need to utilize the sine law again to find the length of segment CD or the width of the field:
$\frac{sin(27)}{1509.66} = \frac{sin(5)}{CD}$
$CD=290$

ANSWER: The width of the field is 290 ft.
