It's hard to read your picture

But if your equation is
(-3)^2 + (-2)^3

then its:

-3*-3 + -2*-2*-2 = -9 - 8 = -17

Since the -3 is in a parenthesis the answer to (-3)^2 is 9 so..

(-3)^2+(-2)^3

-3*-3 + -2*-2*-2=9-8=1

Order the fractions from least to greatest

My name is Ann [436]

Answer:

1/4, 2/5, 1/2, 3/5, 2/3, 13/18, 7/9, 5/6, 2 6/15, 2 4/9, 2 3/5, 2 2/3, 6 3/8, 6 1/2,

6 3/4, 6 5/6

Step-by-step explanation:

I like to organize decimals more than fractions because it's easier for me, so I'm changing each of them to a decimal. You don't have to do this though.

To change a fraction to a decimal, if it is simplified, make it an improper fraction
Then, divide the numerator from the denominator. For example, 1/4 = 0.25 because 1 divided by 4 = 0.25

3/5 = 0.60,
1/4 = 0.25,
1/2 = 0.50,
2/5 = 0.40,
7/9 = 0.7 repeating or just 0.78 rounded,
13/18 = 0.72 repeating or 0.73 rounded,
5/6 = 0.83 repeating or 0.84 rounded,
2/3 = 0.66 repeating or 0.67 simplified,
6 3/4 = 27/4 or 6.75,
6 1/2 = 13/2 = 6.50,
6 5/6 = 41/6 = 6.83 repeating or 6.84
6 3/8 = 51/8 = 6.375 or 6.38
2 2/3 = 8/3 = 2.66 repeating or 2.67
2 6/15 = 36/15 = 2.40
2 3/5 = 13/5 = 2.60
2 4/9 = 22/9 = 2.44 repeating or 2.45

Ordering them is pretty easy, just start from the smallest and move to the greatest!

0.25 = 1/4
0.40 = 2/5
0.50 = 1/2
0.60 = 3/5
0.67 = 2/3
0.73 = 13/18
0.78 = 7/9
0.84 = 5/6
2.40 = 2 6/15
2.45 = 2 4/9
2.60 = 2 3/5
2.67 = 2 2/3
6.38 = 6 3/8
6.50 = 6 1/2
6.75 = 6 3/4
6.84 = 6 5/6

Graph the following set of parametric equations on your calculator and select the matching graph.

Anettt [7]

Answer:

Graph 2

Step-by-step explanation:

The equation x = t² - 3 is represented by exponential growth, ( t² ) so it's graph will be similar to the first graph, graph 1, in our options. Then again we have to consider the equation y = √t - 2, which will be similar to graph 4, but with a greater slope. This leaves us with a solution of graph b.
