The graphs shown are of the form y = ax2. Which graph has the smallest value for a?
Talja [164]
y= x^{2} is a parabola (looks like the letter U).

The letter a represents the coefficient of x^{2} and it controls two things (1) how wide or narrow the parabola is and (2) whether it is concave up (like a U) or concave down (like an up-side-down).

The absolute value of a (the number without the sign) controls how wide or narrow it is. If the absolute value is a fraction less than 1 the graph gets wider. The smaller the absolute value of the fraction the wider the graph gets.

If the absolute value of a is greater than 1 the graph gets narrower (it gets skinnier). The bigger the absolute value the narrower the graph.

So, if all the graphs look like a U (concave up) then the one with the smallest a is the one that is the widest.

The a also controls whether the graph is concave up or concave down. If a is negative

If a is negative the graph is concave down so any graph that is concave down has a smaller value of a than any graph that is concave up. However, if the graph is concave down the one with the smallest a would be the most narrow one.

So to find the one with the smallest a...
If they are all concave up (like a U) pick the widest one
and
If they are not all concave up pick the narrowest one that is concave down (looks like an upside down U)

The length of a rectangular map is 15 inches and the perimeter is 50 inches find the width<br>​
lesya692 [45]

Answer: 10

Step-by-step explanation: 15*2=30,

then you take 50 and subtract 30 from it that leaves you with 20

You then take that 20 and divide it by 2 (because there are two sides that have the width) you get 10

Answer:

x = 5

Step-by-step explanation:

{2}^{2x - 3}   + 52 = 180

{2}^{2x - 3 }  = 128

{2}^{2x - 3}  =  {2}^{7}

2x - 3 = 7

2x = 10

x = 5
