Answer:
Continuous graph:
- The height of a plant as it grows
- Amount of fuel and distance traveled.
Discrete graph:
- Number of students per teacher
- Amount of chairs for each table
Step-by-step explanation:
In mathematics "discrete" means specific points that do not possess a continuous line but only the plotting of points above certain integer values. On the other hand, the word "continuous" in mathematics would be a graph that has a constant smooth line that lacks jumps between values and sometimes decimal numbers.
"The number of students per teacher" would be discrete as the amount of students per teacher would be a fixed integer value.
"The height of a plant as it grows" would be continuous as the height of the plants increases the longer it grows. This would be represented by a straight continuous line.
"Amount of fuel and distance traveled" would be continuous as the amount of fuel used correlates with the distance traveled, which can be represented with a continuous line.
"Amount of chairs for each table" would be discrete as it would be a set integer value for the amount of chairs at each table, not a continuous line.

Factor -4 out of -12r + 20.
Answers
Answer:-12r+20=-4(3r-5)
Step-by-step explanation:
Pls mark as brainliest
Answer:
-4(3r + 5)
Step-by-step explanation:
To factor -4 out of -12r + 20, we need to find out what are the factors that can be multiplied with -4 to get a product of -12r and 20.
To get a product of -12, we must multiply -4 by 3r.
And to get a product of 20, we must multiply -4 by -5.
Therefore, the correct answer is: -4(3r - 5)

The expression means that if Harold has one pack of red sticks and one pack of blue sticks, he could distribute them equally among 4 people without having any sticks of either color leftover.
Step-by-step explanation:
An object is thrown upwards with a speed of 20 m/s. After t seconds, its height can be solved using the formula h = 20t - 4.9t2 where h is the height and t is the time. After how many seconds is the object 19.6 meters high?
Answers
Step-by-step explanation:
h= 20t - 4.9t^2
when h=19.6m
19.6=20t - 4.9t^2
4.9t^2 -20t+19.6=0
solving quadratically
t= 1.64 seconds or t= 2.45 seconds

How can you tell if an equation (for example, x=16+3y (don’t solve this)) will be represented by a straight line when graphed on a coordinate plane? Is there an easy way to tell or how do you figure that out?
Answers
Answer:
I know it is a straight line because I can convert it into standard or slope intercept form. An example of when something isn't a straight line is like y=|x|.
x=16+3y
-3y=-x+16
y=1/3x-16/3
If the variable looks like x^2 or something, then it will not be a straight line.
For any linear function f(x) = mx + b, when does kf(x) = f(kx)?
Answers
Only when b = 0 or k = 1.
If f(x) = mx + b, then
f (kx) = m (kx) + b = mkx + b
while
k f(x) = k (mx + b) = kmx + kb
The two expression are identical only if
kb = b ===> kb - b = 0 ===> b (k - 1) = 0 ===> b = 0 or k = 1

Which equation shows that the product of a square matrix A and its identity matrix I is A?
Answers
Answer:
Option B
Step-by-step explanation:
The multiplication process of matrices works by multiplying the first row of the first matrix by the first column of the second matrix. The same goes with the second row of the first matrix by the second column of the other matrix. Below is the solution why option B is the correct answer.
[tex]A = \left[\begin{array}{ccc}8&11\\13&5\\\end{array}\right][/tex]
[tex]B = \left[\begin{array}{ccc}1&0\\0&1\\\end{array}\right][/tex] ← This is the Identity Matrix.
The attached screenshot shows the solution of the multiplication process. In essence, if you multiply any matrix by the identity (Matrix B), you should end up with your original matrix. Thus, multiplying Matrix A by the Identity matrix results in the same values as Matrix A.
Therefore, the correct answer is B.

Which is the image of the point (9,-4) after a reflection about line y = 2 then translated along the vector <-2,4>?
A. (7,4)
B. (9,8)
C. (7,0)
D. (7,12)
Answers
=======================================================
Explanation:
Start at (9,-4). Move 6 units up to arrive at (9,2). This second point is on the horizontal mirror line of y = 2. We move another 6 units to get to (9,8).
Going from (9,-4) to (9,8) represents reflecting over the line y = 2.
Now apply the translation vector <-2,4> which says "shift to the left 2 units and shift up 4 units". That translation vector is the same as writing the rule [tex](x,y) \to (x-2,y+4)[/tex]
Applying that translation to the point (9,8) moves us to (7,12)
