Step-by-step explanation:

y=x^2-8x+1

-b/2a=x

y = ax^2 + bx + c

a=1 b=-8 c=1

x=8/2(1)

x=8/2

4 is the x of the vertex

y=4^2-8(4)+1

y=16-32+1

y=-15

(4, -15)

A local grocery store is giving out
Marat540 [252]

Answer:

The original price range of soda is $10 to $39.4

Step-by-step explanation:

Given as :

The discount coupon applied on grocery = 5%

The cost of soda after discount coupon ranges = $0.50 to $1.97

Let the original price range of soda = $A

Now, According to question

discount on original price = the cost after discount

So, initial original price = x

5% of x = $0.50

0.05 × x = $0.50

∴ x = \dfrac{0.50}{0.05}

i.e x = $10

Again final original price = y

5% of y = $1.97

0.05 × y = $1.97

∴ y = \dfrac{1.97}{0.05}

i.e y = $39.4

So, The original price range of soda = $A = $10 to $39.4

Hence, The original price range of soda is $10 to $39.4  Answer

sweet [91]
<span>the answer: the main condition can be found one of the following given methods: if A = B*C*D, if we want to find the value of B, so B = A /C*D, the similar method can be applied to find the value of C an D. These are C= A/ B*D and D = A /C*B in our case we have C = 2*Pi* R, if we want to find the value of Pi, it is Pi = C / 2*R the true answer is D</span>
