First, you must know what 5^2 and 5^3 are equal to.

5^2 = 5 * 5 = 25

5^3 = 5 * 5 * 5 = 125

If x^2 is equal to 25, x = 5. If x^2 is greater than 25, x > 5. If x^2 is less than 25, then x < 5.

If x^3 is equal to 125, x = 5. If x^3 is greater than 125, x > 5. If x^3 is less than 125, then x < 5.

x^3 = 15; x < 5

x^2 = 25; x = 5

x^3 = 36; x < 5

x^2 = 49; x < 5

x^2 = 50; x > 5

x^3 = 125; x = 5

Triangle ABC has vertices at (3,1) and (6,4).Rotate this triangle 180 degrees about the origin then reflect it over the Y-Axis.

Tems11 [23]

Answer:

3, -1

6,-4

IDK about the third vertices, you didn't give the original coordinates!

Step-by-step explanation:

180 degree rotation= (x,y) to (-x,-y)

3,1 goes to -3,-1

6,4 goes to -6, -4

IDK about the third vertice, you didn't mention it.

Reflection over y-axis= (x,y) to (-x,y)

-3, -1 goes to 3, -1

-6,-4 goes to 6,-4

hope this helps!

Sketch these cartesin products on the x-y plane R^2<br><br> 14. 11,21x1,1.5,2

ale4655 [162]

Answer:

$\left\{11, 21\right\} \times \left\{1, 1.5, 2\right\} = \left\{ (11, 1), (11, 1.5), (11, 2), (21, 1), (21, 1.5), (21, 2)\right\}$

Step-by-step explanation:

The Cartesian product between two discrete sets, is given by all possible ordered pairs originated with the combinations of the elements of the two sets, thus the requested Cartesian product is:

$\left\{11, 21\right\} \times \left\{1, 1.5, 2\right\} = \left\{ (11, 1), (11, 1.5), (11, 2), (21, 1), (21, 1.5), (21, 2)\right\}$

$A = (11, 1)\\B = (11, 1.5)\\C = (11, 2)\\D = (21, 1)\\E = (21, 1.5)\\F = (21, 2)\\$

The Lisbon’s new heat pump cost $4,500.

Alex73 [517]

Answer:

4.1 years.

Step-by-step explanation:

We have been given that The Lisbon’s new heat pump cost $4,500. They bought it to replace their old furnace and air conditioner which cost about $2,800 a year to run. The heat pump will save them approximately 39% a year.

Yearly cost was 2800 at first and the pump will save 39% of 2800. So annual saving with new heat pump will be:

$\frac{39}{100}*2800=0.39*2800$
