Ruby's math teacher finds that there's roughly a linear relationship between the
amount of time students spend on their homework and their weekly quiz scores. This
relationship can be represented by the equation y=55 + 6x, where y represents
the expected quiz score and x represents hours spent on homework that week. What
is the meaning of the x-value when y = 76?

Answers

Answer 1
It’s y= 61 because if 55 + 6 = 61 I need the points please
Answer 2

Answer: The number of hours a student should spend on their homework to expect a score of 76 on the quiz.

A square and a rectangle have equal area.The rectangle is 64 cm by 81 cm. What is the perimeter of the square?

Answers

Answer:

2592 cm

Step-by-step explanation:

square area = x²

rectangle area = bh

so

x² = bh

since the areas are equal

b and h are in the problem as 64 and 81

x² = 64x81

x² = 5184

divide by 2

x = 2592 cm

Step-by-step explanation:

The First graph shows only the solutions to the inequality that makes sense for this situation.

What is Inequality?

Relation between two mathematical identities which is not equal that is it can be either greater than or less than or greater and equals to or less and equals to etc, is called Inequality.

In the given problem the variable is the number of cars.

Let us assume that the variable c represents the variable quantity which is the number of cars for the inequality.

Now we know that number of cars is always a positive and whole number.

So the suitable inequality to represent the condition that the number of cars is not more than 7 that is less than or equals to 7 is,

[tex]c \leq 7[/tex]

So the solutions are c=0,1,2,3,4,5,6,7

Hence the first graph shows the correct solution for the given inequality condition.

The m is the slope, while the (x1,y1) refers to the point the line goes through.

13.65 = h + 4.88 What the answer

Answers

Answer:

h = 8.77

Step-by-step explanation:

Isolate the variable, h. Note the equal sign, what you do to one side, you do to the other. Subtract 4.88 from both sides:

h + 4.88 = 13.65

h + 4.88 (-4.88) = 13.65 (-4.88)

h = 13.65 - 4.88

h = 8.77

8.77 is your answer for h.

Step-by-step explanation:

The sum of angles in a triangle is 180 degrees. So the third angle in the triangle is

90+32+a=180

a+122=180

a=58

Now angle x is adjacent to angle a so their sum must equal 180 degrees so

x+58=180

x=122 degrees

In the function f(x), x is replaced with 3x.

What effect does this have on the graph of the function?
A. The graph is vertically stretched by a factor of 1//3.
B. The graph is vertically compressed by a factor of 1/3.
C. The graph is horizontally stretched by a factor of 1/3.
D. The graph is horizontally compressed by a factor of 1/3.

Answers

Just took the test, so the answer is...

D. Horizontally compressed by a factor of 1/3

[tex]f(x)=\frac{1}{2}sin(x)-4[/tex] is horizontally compressed by a factor of 1/3 to get [tex]f(x)=\frac{1}{2}sin(3x)-4[/tex]

Option D is correct

What is horizontal compression?

Note that:

If a function [tex]f(x)=Asin(x)[/tex] is transformed to [tex]g(x)=Asin(kx)[/tex], it means that the function f(x) is horizontally compressed by 1/k

Relating this rule to the given function [tex]f(x)=\frac{1}{2}sin(x)-4[/tex]

If x is replaced with 3x, the function will become:

[tex]f(x)=\frac{1}{2}sin(3x)-4[/tex]

This means that the graph of  [tex]f(x)=\frac{1}{2}sin(x)-4[/tex] is horizontally compressed by a factor of 1/3 to get [tex]f(x)=\frac{1}{2}sin(3x)-4[/tex]

A biologist is studying the growth of a particular species of algae. She writes the following equation to show the radius of the algae, f(d), in mm, after d days:

f(d) = 9(1.04)d

Part A: When the biologist concluded her study, the radius of the algae was approximately 12.81 mm. What is a reasonable domain to plot the growth function?

Answers

Answer:

9 days

Step-by-step explanation:

1= 9*(1.04)^d

12.81/9= (1.04)^d

1.423= (1.04)^d

log(1.423)= d *log(1.04)

0.1532=d * 0.017

d= 0.1532/0.017

d=9

The reasonable domain to plot the growth function is in the interval [0,9].
