I would classify that shape as a pentagon because it has 5 sides/edges.

It is shaped like the houses in the old times.

Hope I helped :) :)

Find the ordered pairs for the x- and y-intercepts of the equation 3x − 2y = 18 and select the appropriate option below.

Answer:

B)

Step-by-step explanation:

Y intercept:

Simply substitute all the x values with 0:

When x = 0:

3(0) - 2y = 18

Move the - 2y over to the other side making it a +2y:

0 = 18 + 2y

Move the +18 over to the other side making it a -18:

-18 = 2y

Divide both sides by 2:

$\frac{-18}{2} = \frac{2y}{2}$

-9 = y

So y intercept is:

<h3> (0 , -9)</h3>

X - intercept:

Simply substitute all the Y's with 0:

3x - 3(0) = 18

3x = 18

Divide both sides by 3:

$\frac{3x}{3} = \frac{18}{3}$

x = 6

So the X intercept is:

<h3>(6 , 0)</h3>

This means that your guess of B is correct.

Haeden observed that 65% of her coworkers prefer the local talk news radio station. If 28 of her coworkers do not prefer talk ne

vekshin1

Part A

Let x represent the number of coworkers who prefer the talk news radio.

$65$ % prefer the talk news radio,

$100-65=35$ % will be the percentage that corresponds to coworkers who do not prefer the talk news radio.

Part B

We apply ratio to find x.

$65:x$

$35:28$

Hence number that corresponds to 65% will be greater than 28.

If more, less will divide.

This implies that,

$x=\frac{65\times 28}{35}=52$

Hence 52 of her coworkers prefer the local news talk station.

Help me out please!!

AleksAgata [21]

Step-by-step explanation:

1. $(fg)' = f'g + fg'$ (chain rule)

2 $f(x) = x^5\sin{x}$

$\Rightarrow f'(x) = 5x^4\sin{x} + x^5\cos{x}$

BC = 36; D = 15. What is the value of BD - AC.<br> B<br> A<br> BD - AC =

Snezhnost [94]

Answer:

BD - AC = 0

Step-by-step explanation:

Given that:

BC = 36 , CD = 15 and BD = x

As these are forming right angled triangle,

Using Pythagorean theorem,

$(BD)^2+(CD)^2=x^2\\(36)^2+(15)^2 = x^2\\1296 + 225 = x^2\\1521 = x^2\\$

Taking square root on both sides

$\sqrt{x^2}=\sqrt{1521}\\x=39$

As the given shape is rectangular, the sides parallel to each other will have same values.

AB = 15 , AD = 36 and AC = x

$(15)^2+(36)^2 = x^2 \\225 + 1296 = x^2 \\1521 = x^2 \\x = 39$

Now,

BD - AC = 39 - 39 = 0

Hence,

BD - AC = 0
