The vertex of the function f(x) = x² + 12x is,

⇒ Vertex = (- 6, - 36)

A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

Given that;

The function is,

⇒ f (x) = x² + 12x

Now, We can change the function into the form,

f (x) = (x - h)² + k

Where, (h, k) is vertex.

Here, The function is,

⇒ f (x) = x² + 12x

⇒ f (x) = x² + 12x + 36 - 36

⇒ f (x) = (x + 6)² - 36

⇒ f (x) = (x - (- 6))² + (- 36)

Hence, By comparing,

Vertex = (h, k) = (- 6, - 36)

Thus, The vertex of the function f(x) = x² + 12x is,

⇒ Vertex = (- 6, - 36)

Answer:

There are 3 friends (Judy + 2 friends) who won $145.00

They want to share the winnings equally, but they got:

one $100 bill

four $10 bills

five $1 bills.

Assuming that they can share only those bills, the only way to share the winnings equally is:

Each friend gets one $10 bill

Each friend gets one $1 bill

Then each one gets $11.

And there is a surplus of:

one $100 bill (that can't be divided)

one $10 bill (that can't be divided)

two $1 bill (that can't be divided)

Then:

There is a common pool of $100 + $10 + 2*$1  = $112

And each one of the 3 friends gets $10 + $1 = $11

In the case where they can change the bills, each friend will get:

$145/3 = $48.33

Answer:

16 attires

Step-by-step explanation:

Let us represent the number of attires:

Sally has initially = x

Sally lends half her collection of formal attire to her sister Annie

This means, Sally has currently = 1/2x attires

Sally then buys four more attires. If she had 12 attires now.

Hence, this is expressed Mathematically as:

1/2x + 4 = 12

1/2x = 12 - 4

1/2x = 8

x/2 = 8

Cross Multiply

x = 8 × 2

x = 16

Therefore, the amount of attires Sally had initially = 16 attires

Answer:

What they are asking is in which box do each of the following numbers go into.

[tex]\sqrt{2}[/tex] and [tex]\frac{\pi }{2}[/tex] would go in the 'Between 1 and 2' box.

[tex]\sqrt{5}[/tex] goes under the 'Between 2and 3' box.

([tex]\sqrt{3.5}[/tex])^2 is the exact same as 3.5, as the square root and square cancel each other out, so it goes in the 'Between 3 and 4' box.

Hope that this helps!

Answer:

Not, 1

Step-by-step explanation:

The complement of an event denoted as A', can be interpreted as not A. This means that elements not belonging to a A. In probabilistic term, if we have an event A, the complement is f A is the probability that event A does not occur.

The sum of an event A and its corresponding complement must equal to 1.

This is given by the complement rule ;

P(A) + P(A') = 1

Hence, P(A') = 1 - P(A)

Step-by-step explanation:

[x-2y=14, x=-3y+9]

[3y+9-2y=14]

simplify

[-5y+9=14]

isolate y for -5y+9=14:   y=-1

For x=-3y+9, substitute y=-1

x=-3(-1)+9=12

Answer:

267.95cm^3

Step-by-step explanation:

S= 4πr^2

Surface area is 200.96

π= 3.142

200.96= 4×3.142×r^2

200.96= 12.57r^2

r^2= 200.96/12.57

= 15.99

= √15.99

r = 3.9

Volume= 4/3πr^3

= 4/3× 3.142×3.9^3

= 267.95 cm^3

Isabell, can you see that the sides are 2x6 each?   each half of the triangle will make a total rectangle of 2x6 or 12 square meters

there are 4 of those so 48 sq meters plus the base of 4x4 or 16 sq meters

48+16 = 64 square meters total

Answer:

64 meters squared

Step-by-step explanation:

To find the surface area, we need to find the area of all the faces of the shape. We find the area of a triangle with the formula 1/2 x base x height. Since we have a base of 4 and a height of 6 we multiply the numbers together and get 24 then divide by 1/2 which gives us 12. Since there are 4 total triangles, we are going to multiply 12 x 4 which gives us 48. The last face of the triangular prism is the bottom which is a square. The area of a square can be found by multiplying length x width which is 4 x 4 = 16. For the final step we add 48 + 16 = 64.

Answer:

y = 0.75x + 35

Step-by-step explanation:

x = number of minutes for a massage

y = total cure of pedicure and a massage

We can represent the information given as coordinate pais such as:

It would cost Angela $35 if she gets only pedicure => (0, 35)

This implies that she spends 0 minute (x) on massage, while total cost (y) is $35

If she spends 20 mins for massage, total cost would be $50 => (20, 50).

This implies she's spends 20 min (x) for massage, while total cost (y) would now be $50.

We can write an equation in slope intercept form, y = mx + b by finding the slope (m) and y-intercept (b).

✔️Using (0, 35) and (20, 50),

Slope (m) = change in y/change in x

m = (50 - 35)/(20 - 0) = 15/20

m = 0.75

The slope, m = 0.75 represents the cost of massage per minute ($0.75 per minute).

✔️The y-intercept (b) = 35, this is the initial cost without having a massage.

✅To write the equation in slope-intercept form, substitute m = 0.75 and b = 35 into y = mx + b.

Thus:

y = 0.75x + 35
