Actually it's not 1

330 in 4th quadratic is just 30 in 1st and cos is +ve

so you have

sqrt(3)/2 ^2 = 3/4 = 0.75

For the end-of-year party, Mt.Rise Middle School ordered 112 pizzas. There were eight fewer veggie pizzas than there were pepper

rodikova [14]

Let the number of pepperoni pizzas be x
pepperoni = x
veggie = x - 8 [<span>There were eight fewer veggie than pepperoni]
</span>combo = 3x [T<span>here were three times as many combo as pepperoni]
</span>
Given that the total Pizza: 112
x + x - 8 + 3x = 112
5x - 8 = 112
5x = 112 + 8
5x = 120
x = 24

x= 24
x - 8 = 16
3x = 72

So there were 24 pepperoni pizza, 16 veggie pizza and 72 combo pizza

Ierofanga [76]

Answer:

a = 1/2
h = -1
k = -3

Step-by-step explanation:

We assume you want to compare your expression to the form ...

a(x -h)² +k

1/2(x +1)² +k

The multiplier outside parentheses is ...

a = 1/2

The horizontal offset inside parentheses is ...

-h = 1

h = -1

The vertical offset outside parentheses is ...

k = -3
