Answer:
Step-by-step explanation:
hello :
an equation of this graph is : f(x) = a(x-h)²+k when (h,k) the vertex
so : h=5 and k= -4
f(x) = a(x-5)²-4....... now calculate : a
the y- intercept is : - 6.5 means : f(0) = - 6.5
put x=0 and f(x) = - 6.5
you have : -6.5 = a(0-5)²-4
-6.5 = 25a - 4
25a = -2.5 so : a= -2.5/25= 1/10
the equation is :
<h2>f(x) = (1/10)(x-5)²-4</h2>
Answer:
the number of T-shirts bought was 5
Step-by-step explanation:
After using a debit card, to purchase several t-shirts. Your account balance after buying the t-shirts changes by -$30.60. The negative sign means there was a total debit of $30.6 after your transactions. For each t-shirt you purchased , the changes in your account balance was -6.12. If you purchased n T-shirts, the changes would be
n × -6.12 = -6.12n. This means a total debit of 6.12n for all the T-shirts you bought. Therefore,
6.12n = 30.6
n = 30.6/6.12 = 5
So the number of T-shirts bought was 5

Answer:
1/3
Step-by-step explanation:
How many multiples of 6 are there in 12?
Well there's 6 and 12, so 2
How many multiples of 4 are there in 12?
There's 4, 8, and 12
Since 12 is both 6 and 12 we count it as 1
So 2 + 2 = 4
4/12 = 1/3
