Step-by-step explanation:

The 35 batteries are the conductors we need to stay alive and make things work.

We have given that,

If Mary bought 12 of the Brand X batteries.

We have to determine how many of them lasted less than 15 hours.

The data models are visual representations of an enterprise's data elements and the connections between them. By helping to define and structure data in the context of relevant business processes, models support the development of effective information systems.

The batteries are the conductors we need to stay alive and make things work.

Therefore from the graph, we have the answer is 35 batteries.

Answer:

62.12

Step-by-step explanation:

Answer:

g(x) = 3*sin((-15/4)*pi*x + (-15/4)*pi) + 6

Step-by-step explanation:

The function has the form:

g(x) = a*sin(b*x + c) + d

We know that:

The midline is at (-1, 6)

The midline is the value of g(x) when the sin(x) part is equal to zero

Then the midline is y = 6 = d

g(x) = a*sin(b*x + c) + 6

And from this we also know that:

sin(b*-1 + c) = 0,

We also know that the minimum is at (-3.5, 3)

The minimum is the y-value when the sin(x) part is equal to -1

Then

sin(b*-3.5 + c) = -1

And:

g(-3.5) = 3 = a*(-1) + 6

3 = -a + 6

a = -3 + 6 = 3

The equation is something like:

g(x) = 3*sin(b*x + c) + 6

To find the values of b and c, we need to use the two remaining equations:

sin(b*-3.5 + c) = -1

sin(b*-1 + c) = 0

We also know that:

Sin(0 ) = 0

sin( (3/2)*pi) = -1

where pi = 3.14

Then we can just write:

b*-1 + c = 0

b*-3.5 + c = (3/2)*pi

From the first one, we get:

-b + c = 0

c = b

Replacing that on the other equation we get:

c*-3.5 + c = (3/2)*pi

c*(-3.5 + 1) = (3/2)*pi

c*(-2.5) = (3/2)*pi

c = (3/2)*pi/(-2.5)

and:

-2.5 = -5/2

c = (3/2)*(-5/2)*pi = (-15/4)*pi

Then the equation becomes:

g(x) = 3*sin((-15/4)*pi*x + (-15/4)*pi) + 6

The  trigonometric function equation becomes [tex]g(x)=3 sin(-1.88x-1.88)+6[/tex]

The function has the form:

             [tex]g(x)=a sin(bx+c)+d[/tex]

The midline is at (-1, 6)

So, the midline is y = 6 = d

[tex]g(x)=a sin(bx+c)+6[/tex]

We know that the midline is the value of g(x) when the sin(x) part is equal to zero

Given that The function intersects its midline at (-1,6) and has a minimum point at (-3.5,3).

[tex]sin(-1*b + c) = 0,[/tex]

The minimum is the y-value when the sin(x) part is equal to -1

       [tex]sin(-3.5*b + c) = -1[/tex]

  Since,   [tex]g(-3.5) = 3 = a*(-1) + 6[/tex]

                 [tex]a = -3 + 6 = 3[/tex]

Now equation become,

            [tex]g(x) = 3*sin(b*x + c) + 6[/tex]

To find the values of b and c, we need to use the two remaining equations:

             [tex]sin(-3.5b + c) = -1=sin( (3/2)* \pi)\\\\ -3.5b + c = (3/2)* \pi[/tex]

            [tex]sin(-1b + c) = 0=sin(0)\\\\-b+c=0\\\\b=c[/tex]

Substituting b = c in above equation and [tex]\pi=3.14[/tex]

We get,

            [tex]-3.5c + c = (3/2)*\pi\\\\-2.5c=4.71\\\\c=-1.88[/tex]

also    [tex]b=-1.88[/tex]

Therefore, equation becomes [tex]g(x)=3 sin(-1.88x-1.88)+6[/tex]

Answer:

y = (x+1)^2+5

Step-by-step explanation:

Add or subtract from both sides to complete the square;

y=x^2+2x+6; Subtract 5 from both sides

y-5 = x^2+2x+1; Factor;

y - 5 = (x+1)^2; Add 5 back to both sides;

y = (x+1)^2+5

Answer:

y=(x+1)²+5

Step-by-step explanation:

y=x^2+2x+6

a=1; b=2;c=6

subtract 6 from both sides: x^2+2x= -6

complete the square by using the equation (b/2)^2 and add to both sides: x^2+2x+1=-6+1

simplify: x^2+2x+1=-5

find the factors of 1 that add up to 2: 1 and 1

(x+1)(x+1)=-5

add 5 to both sides and simplify

y=(x+1)^2+5
