Answer:

AC is the longest side

AB is the shortest side

Step-by-step explanation:

We can find the third angle

A+B+C = 180

55+80+C = 180

135+C = 180

C = 180-135

C =45

The longest side is opposite the largest angle

B is the largest angle so AC is the longest side

C is the the smallest angle so AB is the shortest side

The graph of the function f(x) = ax^2 + bx + c has vertex at (0, 2) and passes through the point

Ann [662]

Answer:

Step-by-step explanation:

You need to use vertex form of a quadratic to solve this.

Consider the vertex to be $(h,k)$

Another way of representing a quadratic is in "vertex form":

$f(x) = a(x-h)^2+k$

Now all you have to do is solve for a. You know that the vertex is $(0,2)$ and you have know the point of $(1,8)$ . Now, all you have to do is plug in these values and solve for a.

$8 = a(1-0)^2+2\\8=a(1)^2+2\\8=a+2\\a=6$

Now you know the equation is $f(x) = 6(x-0)^2+2$ , but you need it in quadratic form. All you have to do is solve is distribute the 6:

$6x^2+2$

You get:

a = 6

b = 0

c = 2

Hungary's ratio of female to male athletes is 5:9. If Hungary brought 25 female athletes, how many

gulaghasi [49]

Answer:

Let the number of females and males be 5x and 9x respectively.

Given - number of females = 25

Therefore ,

$5x = 25 \\ x = \cancel \frac{25}{5} = 5$

Then ,

$number \: of \: males = 9x \\ = > 9(5) \\ = > 45$
