Researchers investigated the possible beneficial effect on heart health of drinking black tea and whether adding milk to the tea

reduces any possible benefit. Twenty-four volunteers were randomly assigned to one of three groups. Every day for a month, participants in group 1 drank two cups of hot black tea without milk, participants in group 2 drank two cups of hot black tea with milk, and participants in group 3 drank two cups of hot water but no tea. At the end of the month, the researchers measured the change in each of the participants’ heart health.

Describe the pattern that you see in the table for the right column. Please help me describe it in complete sentences. Extra poi
Gwar [14]

The pattern on the table is x increases:

  • The sine of x increases
  • The cosine of x increases
  • The function sin²(x) + cos²(x) remains constant

<h3>How to describe the pattern?</h3>

The functions on the table of values are:

sin(x), cos(x) and sin²(x) + cos²(x)

To describe the pattern, we simply observe how the values of the function change, as x increases.

As x increases, on the table:

  • The sine of x increases
  • The cosine of x increases
  • The function sin²(x) + cos²(x) remains constant

Harry earns $45 a week more than Xena. George earns $18 a week less than Xena. If Harry earns the same amount in two weeks that
12345 [234]

Answer:

Xena earns $144 per a week.

Step-by-step explanation:

Harry earns - $ h

Xena earns - $ x

George earns -$ g

Harry earns $45 a week more than Xena.      h= x+45

George earns $18 a week less than Xena.     g = x - 18

If Harry earns the same amount in two weeks that George earns in three weeks

2h = 3g

So, we have the system of 3 equations:

h= x+45

g = x - 18

2h = 3g    (*)

Substitute values of h and g into equation (*)

2(x+45) = 3(x-18)

2x + 90 = 3x - 54

90+54 = 3x- 2x

x= 144

William is going to the amusement park, where he has to pay a set price of admission and another price for tickets to go on each
Mice21 [21]

The point (1, 20) means that the total money spent for purchasing one ticket is $20.

<h3>Linear equation</h3>

Linear equation is in the form:

y = mx + b

where y, x are variables, m is the slope of the line and b is the y intercept.

Let y represent the total money spent for buying x number of tickets.

The point (1, 20) means that the total money spent for purchasing one ticket is $20.
