How does the graph of y=ax^2+c compare to a graph off y=ax^2?

1 answer:

3 0

Shifting a graph up by c units involves adding c to the whole function

therefor
y=ax^2+c is c units higher than y=ax^2 (aka, it is shifted c units up)

Two rectangles have the same area. One says x + 3 and x + 1 and the other says x + 6 and x. What is the value of x?

Taya2010 [7]

(x+3)(x+1)=(x+6)(x)
x^2+x+3x+3=x^2+6x
x^2+4x+3=x^2+6x
4x+3=6x
3=2x
x=1.5

Hope this helps :)

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

If you flip 2 coins, what is the probability of getting exactly 2 heads

Ahat [919]

Answer:

This states that the probability of the occurrence of two independent events is the product of their individual probabilities. The probability of getting two heads on two coin tosses is 0.5 x 0.5 or 0.25.

Step-by-step explanation:

The probability of getting 2 heads with 2 coins can be broken into 2 steps:

The first coin must show Heads AND

the second coin must show Heads.

p(h,h)= P(H) <----- and means multiply

P(H) x P(H)= 1/2 x 1/2 =1/4
