Bernice sells 135 seashells by the seashore every day. She sells each sea shell for 3 dollars. For how many days does Bernice ne
slavikrds [6]

Answer:

Bernice would need 6 days assuming that everything remains constant to make $2430.

Step-by-step explanation:

Assuming she sells every single seashell every day.

First, find the total amount she makes per day by multiply the amount she sells them for ($3) with the total amount of sea shells she sells each day ($135):

135 x 3 = $405

Bernice makes $405 each day.

Now, to solve for the amount of days, divide the total amount she wants to make ($2430) with the amount she makes per day ($405):

2430/405 = 6

Bernice would need 6 days assuming that everything remains constant to make $2430.

Write the equation of the function whose graph is shown. y = (x + )2 +
Deffense [45]
Quadratic form is given in the form
y= ax^{2}+bx+c, where a, b, and c are constants

We substitute the value (8, 12) and (5,3) in turn

12= a(8)^{2}+b(8)+c
12=64a+8b+c ... Equation 1

3=a(5)^{2}+b(5)+c
3=25a+5b+c ... Equation 2

Equation 1 - Equation 2 gives
39a+3b=9, we call this Equation 3

We also know that (5, 3) is the turning point of the curve, where the value of x is given by x=- \frac{b}{2a}
Substitute x=5
5=- \frac{b}{2a}
10a=-b
b=-10a ... Equation 4

Substitute Equation 4 into Equation 3
39a+3b=9
39a+3(-10a)=9
39a-30a=9
9a=9
a=1

Now we need to work out the value of b and c

Substitute a=1 back into equation 4
-10a=b
-10(1)=b
b=-10

Substitute a=1 and b=-10 into either equation 1 or equation 2

64a+8b+c=12
64(1)+8(-10)+c=12
64-80+c=12
c=12+80-64
c=28

Hence the equation of the quadratic curve is
y= x^{2} 10x+28
