On a number line, the coordinate of X is 52, the coordinate of Y

Mathematics
1 answer:
ASHA 777 [7]2 years ago
8 0

Answer:

No

Step-by-step explanation:

since the magnitude of xy ≠ zw,

|x-y| = xy = |52-121|= 69, |z-w| = zw = |-21-25| = 46

69 ≠ 46

Which sequence is modeled by the graph below? coordinate plane showing the points 1, 1; 2, 2; 3, 4; and 4, 8
Alex17521 [72]
The points of the graph are: (1,1), (2,2), (3,4), (4,8).

Then the sequence is:

- for the x-coordinate: 1, 2, 3, 4, 5, 6, 7, ...

- for the y-coordinate: 1, 2, 4, 8, which is: 2^0, 2^1, 2^2, 2^ 3, ... so the next y-coordinates are 16, 32, 64, 128, ...

So, the sequence is: 1, 2, 4, ,8, 16, 32, .... 2^x.

Answer:

144 cm^{2}

Step-by-step explanation:

<u>Step 1: Find the true length of each side</u>

We know that the perimeter is 56cm and the ratio of AD:AB:DC:BC is 5:12:6:5. It is safe to assume that this ratio is the simplified version, which means that if we multiply each of these numbers by a scale factor of x, then we get the true length of each side, so we would get 5x, 12x, 6x, 5x for the sides. We also know that when we add these numbers, we get the perimeter, which is 56. So, we can create the equation 5x + 12x + 6x + 5x = 56. Then, solve the equation for x, which would be 2, and go back and multiply each number with 2 to get the following:

AD = 5*2 = 10cm, AB = 12*2 = 24cm, DC = 6*2 = 12cm, BC = 5*2 = 10cm  

<u>Step 2: Calculate the Height</u>

Now we know the lengths of each side, lets take a look at the formula for the area of a trapezium: \frac{base_{1}  + base_2}{2}*height. So, the next step would be to calculate the height. We can draw the height by drawing a line straight down from the vertex D and another straight down from the vertex C. These lines are both the height, and will be the exact same length. We can calculate that the height is 8 because AB is 24 cm, but the length from the height at vertex D to the height at vertex C is 12 cm, so that means that the base of each triangle is 12/2 = 6 cm. Then we can use Pythagorean theorem to figure out that the height is 8cm.

<u>Step 3: Calculate the Area</u>

Lastly, we can calculate the area. The formula is \frac{base_{1}  + base_2}{2}*height. In this case, the numbers would be \frac{12 + 24}{2} * 8 = 144cm^{2}

I know this is a lot, so let me know if you have any questions!
