Find the area of the triangle enclosed by these lines with the following vertices. y = x, x = 0, y = 5 (0,0), (0,5), (5,5)

Lina20 [59]

The are of the triangle will be 12.5 units.

On marking the given vertices (0,0), (0,5), (5,5) of the triangle we get, the base of the triangle = 5 units and height of the triangle = 5 units.

Now, we know area of triangle = $\frac{Base * Height}{2} \\ \\ = \frac{5 *5}{2} \\ \\ = \frac{25}{2} \\ \\ = 12.5 units.$

Allie charges $12.49 for each delivered meal. If a 7 percent sales tax is applied, what is the total cost of the meal?

The multiplier for a 7% increase is 1.07.
Time the price by the multiplier:

12.49 x 1.07 = $13.36

Which expression is equivalent to 64y^18-1000z^6?

Shalnov [3]

For this case we must find an expression equivalent to: $64y ^ {18}-1000z ^ 6$

Then, we take common factor 8:

$8 (64y ^ {18}-125z ^ 6) =$

By definition of power properties we have to:

$(a ^ n) ^ m = a ^ {n * m}$

So:

$8 ((2y ^ 6) ^ 3- (5z ^ 2) ^ 3)$

Since both terms are perfect cubes, we factor using the cube difference formula:

$(a ^ 3-b ^ 3) = (a-b) (a ^ 2 + 2ab + b ^ 2)$

Where:

$a = 2y ^ 6\\b = 5z ^ 2$

So: $8 (2y ^ 6-5z ^ 2) ((2y ^ 6) ^ 2 + 2 (2y ^ 6) (5z ^ 2) + (5z ^ 2) ^ 2) =\\8 (2y ^ 6-5z ^ 2) (4y ^ {12} + 10y ^ 6z ^ 2 + 25z ^ 4)$

Answer:

$8 (2y ^ 6-5z ^ 2) (4y ^ {12} + 10y ^ 6z ^ 2 + 25z ^ 4)$

Jill has a photograph that is 4 inches wide by 6 inches high. If she enlarges it so that the width is 12

Nadya [2.5K]

Answer:

The inches in height will be 18 inches.

Step-by-step explanation:

Okay so we know that the original width is 4 inches and she enlarged that to 12 inches

So what we first have to do is find out how much did the photograph "grow" per se. To find this we have to divide 12 by 4. 12 divided by 4 = 3.

So, the width of the photograph grew "times 3" inches

Now whatever you do to the width you have to do to the height. In this case, what is "3 times" 6 (which is the height). 3 times 6 = 18 inches

So in simpler words 12 divided 4 = 3 x 6 = 18 inches

The inches in height will be 18 inches.

Jill has a square with a width of 12 inches, and a height of 18 inches.

Have a wonderful day!
