Answer:

C

Step-by-step explanation:

As we know vertex -

[tex]y=a(x+3)^2-4[/tex]

Passes through (1,4). Substitute x = 1 and y = 4

[tex]4=a(1+3)^2-4\\4=a(4)^2-4\\4=16a-4\\4+4=16a\\16a=8\\a=\frac{8}{16}\\a=\frac{1}{2}[/tex]

Therefore the vertex equation is [tex]y=\frac{1}{2}(x+3)^2-4[/tex]

Since you want the "standard" form then..

[tex]y=\frac{1}{2}(x^2+6x+1)\\y=\frac{1}{2}x^2+3x+\frac{1}{2}[/tex]

So the standard form is 1/2x^2 + 3x + 1/2

Answer: It is a composite number since it has more factors than just itself and 1.

Step-by-step explanation:

1x20=20

2x10=20

4x5=20

Answer:

composite

Step-by-step explanation:

It has factors other than 1 and 20; Its factors are 1, 2, 4, 5, 10, and 20.

Answer:

0.00004

Step-by-step explanation:

Given that:

n = 50

Number of options = 4 ; 1 is the correct answer

Hence ;

p = 1/4 = 0.25

Using normal approximation :

Mean (m) = np = 50 * 0. 25 = 12.5

Standard deviation (s) = √(n*p*q)

q = 1 - p = 1 - 0. 25 = 0.75

s = √(50*0.25*0.75) = 3.062

At least half the question :

Half the question = 1/2 * 50 = 25

P(X ≥ 25) = P(X ≥ 24.5)

(x - m) / s

P(X ≥ 24.5) = (24.5 - 12.5) / 3.062

= 12 / 3.062

= 3.919

P(Z ≥ 3.919) = 0.00004 (Z probability calculator)

Answer:

Part A: 16x^2 -56x+49

I'm not quite sure on Part B and C though, sorry :/.

Step-by-step explanation:

To find the expression we need to solve (4x-7)•(4x-7)

4x•4x = 16x^2

4x•-7= -28x

-7•4x= -28x

-7•-7=49

Combine alike terms

16x^2-56x+49

Answer:

69.1²feet

Step-by-step explanation:

area = pi x r²

11x2= 22

22x 3.14 = 69.08

69.1

The area of the lawn that is being watered is, 380.1 feet².

The area of a circle is π multiplied by the square of the radius. The area of a circle, (A) when the radius 'r' is given is πr2. π is approximately  3.142

here, we have,

area = pi x r²

so,

11^2= 121

121x 3.14

= 380.1

Hence, The area of the lawn that is being watered is, 380.1 feet².

Step-by-step

The graph that represents the function, based on the maximum and minimum values, and the period of the function, y = cos(4·x) is the option;

The period of a function is the length of the smallest interval over which the function repeats its values.

The function y = cos(4·x) has a maximum value of 1 and a minimum value of -1. '

The period of the function is; 2·π/|4| = π/2, which indicates that the function completes a cycle in an interval of π/2.

The function crosses the y-axis at x = 0, at which y = cos(4 × 0) = 1

The above information indicates that the graph that represents the function is the one that has a maximum of 1 and a minimum, of -1, completes a period at π/2, crosses the y-axis at (0, 1)

The correct option is therefore;

On a coordinate plane, a function  has a maximum at 1, and minimum at negative 1. It completes one period at π/2. It crosses the y-axis at (0, 1)

Step-by-step explanation:

Answer:

y=-1/2x-3 = slope-intercept

y+5=-1/2(x-4) = point-slope

Step-by-step explanation:

I used the slope and the point provided to get other points and eventually the y-intercept to complete the slope-intercept equation.

I plugged in the numbers provided to get the point-slope equation.

Answer:

16

Step-by-step explanation:

Basic Algebra, isolate V.

Do the opposite equation to get V on its own.

Because it is V/8, multiply both sides by 8 to get 8 on its own (if you wanted to move v over you would divide)

[tex]\frac{v}{8} =2[/tex]

[tex]v =2*8[/tex]

[tex]v =16[/tex]

Answer:

The third table.

Step-by-step explanation:

To have a proportional relationship there must be a constant rate of change

6-5 / 9-7 = 1 /2

5-3 /7-4 = 2/3

these are different so this is not a proportional relationship

10-8 /150-120 =2/30

8-5 /120-75 =3/45

these are different so this is not a proportional relationship

10-8 /12-10 =2/2 =1

8-6 /10-8 =2/2= 1

These are the same therefore it is proportional

Answer:

y = -3x + 3.

Step-by-step explanation:

The marked points on the line are (0, 3) and (1, 0) so:

the slope is (3 - 0) / (0 - 1) = -3.

The y-intercept is y = 3.

Therefore the equation of this line is y = -3x + 3.

Answer: 8.50x + 2.25x

Step-by-step explanation:

Answer:

$49.572

Step-by-step explanation:

Given that :

Cost per disc = $18

Number of disc purchased = 3

Discount received = 15%

Sales tax = 8%

Original cost : cost per dic * number purchased

Original cost = $18 * 3 = $54

Discounted price = (100 - 15)% * $54

Discounted price = $45.9

Sales tax :

(100 + 8)% of $45.9

108% * $45.9

= $49.572

Total price = $49.572

Answer:

Step-by-step explanation:

Often, you can work these problems in your head.

If you sold all cookies, your revenue would have been 27×3 = 81. It was 129-81 = 48 more than that. Each muffin generates 4 more revenue than a cookie dies, so there must have been 48/4 = 12 muffins. The 27-12 = 15 were cookies.

You sold 15 cookies and 12 muffins.

__

If you let a variable represent the most expensive item (m for muffins), then you can write an equation for the revenue. You may recognize that some of the steps in the solution match the "verbal" solution above.

  3(27 -m) +7m = 129

  4m +81 = 129

  4m = 129 -81 = 48

  m = 48/4 = 12 . . . muffins

  27-12 = 15 . . . cookies
