The temperature is at its lowest point when = 0 and completes one cycle over a 6-hour period.
b. Find the period, amplitude, and the midline of the graph you drew in part a.
c. Write a function to represent the relationship between time and temperature.
d. What will the temperature of the reaction be 14 hours after it began?
e. At what point during a 24-hour day will the reaction have a temperature of 60℃?

Answer:

Option A

Step-by-step explanation:

Out of 12 contestants, the judges will select either 3 or 4 contestant.

Number of groups that can be formed when judges pick three contestants

[tex]^{12}C_3[/tex]

[tex]220[/tex]

Number of groups that can be formed when judges pick three contestants

[tex]^{12}C_4\\495[/tex]

Number of more  groups that can be formed if the judges  pick four instead of three

[tex]= 495-220 = 275[/tex]

Hence, option A is correct

Answer: $56.20

Step-by-step explanation:

Both the tax and the tips will be based on the total cost:

Tip = 43.57 * 20%

= $8.71

Tax = 43.57 * 9%

= $3.92

Total = Cost + Tip + Tax

= 43.57 + 8.71 + 3.92

= $56.20

Answer:

Una expresión  es un grupo finito de términos algebraicos y símbolos matemáticos combinados en donde las letras se usan para representar números con valores desconocidos o imaginarios.

Una expresión consta de:

Coeficiente: que es el numero que no cambia o varia

Variable: representada por una letra y su valor cambia o fluctúa.

Para el enunciado, las variables son:

X= Nº de reproductores MP3

Y= Nº de reproductores DVD

Y las constantes son las ganancias por la venta de cada articulo

Ganancia de X = 35

Ganancia de Y= 15

La expresión que representa la ganancia por las ventas de MP3 y DVD, será:

G = 35X + 18Y

Answer:

57.4 mph

Step-by-step explanation:

The process will be to divide the number of miles by the amount of time

So,

miles = 296

time = 5 hr 10 min

miles / time

296 / 5 hr 10 min

re-write 5 hr 10 min as 5.16

296 / 5.16

57.4 mph on average

Answer:

64 1/2

Step-by-step explanation:

6(1/4+5/2)-2

parethesis first 1/4 +5/2 make them the same denominator 1/4 + 10/4 = 11/4

then 6 or 6/1 time 11/4 = 66/4= 16 1/2 - 2 = 64 1/2 i havn't done fractions in awhile so im not a 100% certain

Answer:

Mrs. Lopez made 50 quarts of sweet tea

Step-by-step explanation:

A gallon and a quart are two of the five US standard volumes of measurement. In relation to litres, a quart is 946.352946 millilitres while a gallon is  3.7854118 litres.

The relationship between The gallon and The quarts is given as 4:1

This means that for every 4  quarts, there is 1 gallon.

Now, let us find the number of quarts in 12¹/₂ gallons as follows:

1 gallon = 4 quarts

∴ 12¹/₂ gallons = 12¹/₂ × 4 quarts

converting the mixed fraction to improper fraction and multiplying:

= ²⁵/₂ × ⁴/₁

[tex]= \frac{25 \times 4 }{2 \times 1} = \frac{100}{2} \\\\= 50\ quarts[/tex]

Answer: [tex]\dfrac{7}{60}[/tex]

Step-by-step explanation:

Given

Spinner is spun 60 times

7 is obtained seven times

Probability is the ratio of favorable to the possible outcomes.

Here, favorable outcomes occurred 7 times

So, the required probability is

[tex]\Rightarrow P=\dfrac{7}{60}[/tex]

Answer:

The volume of the cylinder is 3,080 cm^3

Step-by-step explanation:

Mathematically, we have the volume calculated as;

V = pi * r^2 * h

r = radius = 14 cm/ 2 = 7 cm (14 cm is the diameter and the radius is half the diameter)

h = height = 20 cm

Substituting these values;

V = 22/7 * 7^2 * 20

V = 22 * 7 * 20

V = 3,080 cm^3

Answer:

To draw the graph of linear equation of the form

 y-a=m (x-b)

We will first write it in slope intercept form which is of the form

It will cut x axis and y axis at ,  respectively.

As Euclid postulate States that, Unique equation of line can be Determined by two points, So join these two points. And Infinite number of points lie on a line.

Graph B

Step-by-step explanation:

The graph that represents the equation y - 2 = 3(x - 1) is: B. Graph B.

y = mx + b is used to represent the equation of a line in slope-intercept form, where, m is the slope and b is the y-intercept of the line.

Given the equation, y - 2 = 3(x - 1), rewrite the equation in slope-intercept form:

y - 2 = 3x - 3

y = 3x - 3 + 2

y = 3x - 1

The slope (m) is 3 and the y-intercept (b) is -1. Thus, the graph that has a slope of 3 and a y-intercept as -1 is graph B.

Angles of a triangle equal 180.

110+x+x+30=180

2x+140=180

2x=40

x=20

If you input 20 as X back into the equation, then you can check that it is the right answer.
