Answer:

<h2>remainder = 9</h2>

<u>Step-by-step explanation:</u>

(x - 2) => x = 2

f(x) = f(2)

<h2>___________</h2>

= 2x³ - 5x² + 3x + 7

= 2(2)³ - 5(2)² + 3(2) + 7

= 2×8 - 5×4 + 6 + 7

= 16 - 20 + 6 + 7

= 29 - 20

= 9

Tracy needs to find the length and width of the equipment storage room where she works. The room is 2 meters longer than it is w
____ [38]

Answer:

3 meters

Step-by-step explanation:

We assume the storage room is a rectangle, like most rooms, no indication it is otherwise.

We know it's a rectangle and not a square because it is longer than wide.

We have the perimeter measurement (16 meters).

So, we can make the following equation:

2x + 2y = 16

x being the width of the room, y being it's length.  A perimeter is the sum of all sides.

We also know the room is 2 meters longer than wide... so:

y = x + 2

If we replace y in the first equation by its value relative to x, we get:

2x + 2(x + 2) = 16 which becomes

2x + 2x + 4 = 16

4x =12

thus x = 3

Width: 3 meters

Length: 5 meters.

Confirms the 16 meters perimeter.

This makes no sense to me keep getting the wrong answers when i try to figure it out
satela [25.4K]
To solve this problem, you'd want to start by finding the mean of the given numbers. To find the mean, add all the numbers together and divide by how many there are.

Next, you'll see that the question says one of the rents changes from $1130 to $930. So find the mean of all the numbers again, except include $930 in your calculation instead of $1130.

I got $990 as the mean for the given numbers, and $970 as the mean after replacing the $1130 with $930. Subtracting the two means gives you $20. So the mean decreased by $20.

Now for the median, all you need to do is find the median of the given numbers and compare them with the median of the new data. Because there are ten terms, you have to add the middle two numbers and divide by two. $990 + $1020 = 2010. 2010÷2 = $1005 as the first median.

The new rent is 930, so you have to reorder the data so it goes from least to greatest again. 745, 915, 925, 930, 965, 990, 1020, 1040, 1050, 1120. After finding the median again you get 977.5. Subtracting the two medians gives you $27.5 as how much the median decreased. Hope this helps!

abruzzese [7]

Answer:

  B)  75π cm³

Step-by-step explanation:

The volume of a cone is given by the formula ...

  V = (1/3)πr²h

Your cone has r = 5 cm and h = 9 cm. Putting these values into the formula gives ...

  V = (1/3)π(5 cm)²(9 cm) = 75π cm³
