Answer:

$250.00

Step-by-step explanation:

twenty $1 bills- 20 x 1 = 20

six $5 bills- 6 x 5 = 30

four $10 bills- 4 x 10 = 40

five $20 bills- 5 x 20 = 100

thirty $1 bills- 30 x 1 = 30

four $5 bills- 4 x 5 = 20

five $10 bills- 5 x 10 = 50

one $20 bill- 1 x 20 = 20

Add the bold totals together and get the final answer of $250.00

Answer:

definition  

The vertex form of a quadratic function is given by

f (x) = a(x - h)2 + k, where (h, k) is the vertex of the parabola.

FYI: Different textbooks have different interpretations of the reference "standard form" of a quadratic function. Some say f (x) = ax2 + bx + c is "standard form", while others say that f (x) = a(x - h)2 + k is "standard form". To avoid confusion, this site will not refer to either as "standard form", but will reference f (x) = a(x - h)2 + k as "vertex form" and will reference f(x) = ax2 + bx + c by its full statement.

When written in "vertex form":

• (h, k) is the vertex of the parabola, and x = h is the axis of symmetry.

• the h represents a horizontal shift (how far left, or right, the graph has shifted from x = 0).

• the k represents a vertical shift (how far up, or down, the graph has shifted from y = 0).

• notice that the h value is subtracted in this form, and that the k value is added.

            If the equation is y = 2(x - 1)2 + 5, the value of h is 1, and k is 5.

            If the equation is y = 3(x + 4)2 - 6, the value of h is -4, and k is -6.

Method 1: Completing the Square

To convert a quadratic from y = ax2 + bx + c form to vertex form, y = a(x - h)2+ k, you use the process of completing the square. Let's see an example.

Answer:

153.86 inches²

Step-by-step explanation:

How do we find the radius of a circle?

How do we find the area of a circle?

Solving

Therefore, the answer is 153.86 inches².

Have a lovely rest of your day/night, and good luck with your assignments! ♡

The area of the circle is 153.86 square inches.

We have,

Diameter = 14 inch

Radius= 14/2 = 7 inch

Now, the formula for area of a circle,

Area = π (radius)²

Now we can calculate the area using the radius:

Area = 3.14 x (7 inches)²

Area = 3.14 x 49 square inches

Area ≈ 153.86 square inches

Therefore, the area of the circle is 153.86 square inches.

Answer:

34 or B

Step-by-step explanation:

180-112=68

68/2=34

Since the 2 angles equal 180, and we already know one is 112, we can subtract that. and because it is 2 times a number, we need to get half of whatever that number is, which was 68, and we got 34. this would be the value of y, because when plugged in, 112+2(34)=180.

Answer:

[tex]y = \frac{2}{3} x + 12[/tex]

Step-by-step explanation:

[tex]y = - \frac{3}{2} x - 1[/tex]

The gradient of a line is the coefficient of x when the equation of the line is written in the form of y=mx+c.

Thus, gradient of given line=[tex] - \frac{3}{2} [/tex].

The product of the gradients of perpendicular lines is -1.

(Gradient of line)(-3/2)= -1

Gradient of line

[tex]- 1 \div ( - \frac{3}{2} ) \\ = - 1( - \frac{2}{3} ) \\ = \frac{2}{3}[/tex]

Substitute m=[tex]\frac{2}{3} [/tex] into y=mx+c:

[tex]y = \frac{2}{3} x + c[/tex]

To find the value of c, substitute a pair of coordinates.

When x= -6, y= 8,

[tex]8 = \frac{2}{3} ( - 6) + c \\ \\ 8 = - 4 + c \\ c = 8 + 4 \\ c = 12[/tex]

Thus, the equation of the line is [tex]y = \frac{2}{3} x + 12[/tex].

The average lap time will be 1.15 minutes. The correct option is  B.

Average is defined as the ratio of the sum of the number of the data sets to the total number of the data. The average actually determines the middle value of the data.

Given that Cheryl ran three laps during her physical education class. If her times were 1.23 minutes, 1.04 minutes, and 1.18 minutes.

The average will be calculated as,

Average = ( 1.23 + 1.04 + 1.18 ) / 3

Average = ( 3.45 / 3 )

Average = 1.15

Answer:

1.D(0, 4) → D'(0, –4)

2.E(–2, 0) → E'(–2, 0)

3.The perpendicular distance from G' to the x-axis will equal 2 units.

4.The perpendicular distance from D' to the x-axis will equal 8 units.

5.The orientation will be preserved.

Step-by-step explanation:

D(0, 4) becomes D'(0, –4) and E(–2, 0) becomes E'(–2, 0).

We know that the rule for reflecting over the X axis is to negate the value of the y-coordinate of each point, but leave the x-value the same.

The coordinate of  D(0, 4) becomes D'(0, –4) and coordinate of E(–2, 0) becomes E'(–2, 0).

3.The perpendicular distance from G' to the x-axis is 2 units.

4.The perpendicular distance from D' to the x-axis is 8 units.

Hence D(0, 4) becomes D'(0, –4) and E(–2, 0) becomes E'(–2, 0).

Initial amount of animal = 10

If her collection continues to grow at a rate of 24% per year, then increment in number of animal after 1 year will be:

24% of 10

= 0.24×10

= 2.4

Total increment after 6years will be:

Total stuffed animal that she will have after 6years = initial amount + increment = 10+14.4

Total stuffed animal that she will have after 6years = 24.4 ≈ 24 stuffed animals
