Mayumi is constructing a line through point P that is perpendicular to RS←→. A horizontal line segment R S and a point P are drawn. The point P is above the horizontal line segment R S. She places her compass on point P to construct an arc. What must be true about the width of the compass opening when Mayumi draws the arc? It must be greater than 12RS. It must be equal to PS . It must be wide enough so that the arc intersects RS←→ in two points. It must be equal to PR .
Answers
Width of the compass should be more than the smallest space between P and RS, so that it cuts RS at two distinct points. Therefore, it must be wide enough so that the arc intersects RS←→ in two points. The photo is attached so that you can understand it more.

Answers
The equation is [tex]p = 5e^{t} +20[/tex].
IntegrationIt is a method of summing up parts to find the whole. It is a reverse process of differentiation.
Given
dp/dt=5e^t
To findThe value of p.
How to get the value of p?dp/dt=5e^t is given
[tex]\begin{aligned} \dfrac{dp}{dt} &= e^{t} \\\int dp &= \int {5e^{t} } \, dt \\\int dp &= 5 \int {e^{t} } \, dt \\p &= 5e^{t} +c\\\end{aligned}[/tex]

−x − 3y = −12
3y + 12
−3y + 12
3y − 12
−3y − 12
2. please check my answer for the picture question
Answers
−x − 3y = −12 → - x = 3.y - 12 → x = -3.y + 12. So I will substitude in the 1st equation, x by -3.y + 12 (2nd answer)
2) you follow the same logic as previously done
and you will find 2x+4y ≥ -16.
Isolate y → 4y ≥ - 2x - 16→→y ≥ - x/2 -4
1st you notice that it's a straight line (and not - - - ), then the equation should have ≥ (and not > )
2nd) It's decreasing that means a<0 (a= - 1/2)
3rd) for x = 0 ; y = -4
All that satisfies the equation y ≥ - x/2 -4 OR 2x+4y ≥ -16 (last answer)

How do you find the median of these numbers $17.49, $11.29, $16.89, $11.79?
Answers
The median is the middle number in a set after you place them least to greatest:
$11.29, $11.79, $16.89, $17.49
Well, since the numbers in the set are even, meaning there are only 4 numbers, we pick out the 2 middle numbers which would be, $11.79 and $16.89. Find the average (add them and divide by 2) and you'll get the median.
$11.79 + $16.89 = $28.68/2 = $14.34
Thus, the median is: $14.34

Two buses are traveling to a state park. One bus leaves the terminal at 4:00 p.m. and travels at 40 miles per hour. The second bus leaves the terminal at 5:00 p.m. and travels at 60 miles per hour.
How much time passes until the second bus catches up with the first bus?
Answers
Final answer:
The second bus catches up with the first bus in 2 hours.
Explanation:
To calculate how much time passes until the second bus catches up with the first bus, we need to find the distance between them when the second bus starts and the relative speed between the two buses.
When the second bus starts, the first bus has already traveled for 1 hour (from 4:00 p.m. to 5:00 p.m.) at a speed of 40 mph. Therefore, the first bus has covered a distance of 40 miles.
The relative speed between the two buses is the difference in their speeds, which is 60 mph - 40 mph = 20 mph.
Using the formula: t = d / v, where t is the time, d is the distance, and v is the speed, we can calculate the time it takes for the second bus to catch up with the first bus:
t = 40 miles / 20 mph = 2 hours.
Therefore, it takes 2 hours for the second bus to catch up with the first bus.

What is the scale factor use to create this dilation?
Answers
So the "before" is the large solid triangle and the "after" is the smaller dashed triangle.
The horizontal side of the solid triangle is 15 units. The corresponding side for the dashed triangle is 3 units. Dividing the two values gives: 3/15 = 1/5 = 0.2
Make this value negative. The reason why is due to the fact that we have a sort of reflection going on as we're scaling down the figure.
So the final answer is -0.2

A line goes through the point (6,–2) and has a slope of –3.
What is the value of a if the point (a,7) lies on the line?
Answers
slope(m) = -3
(6,-2)...x = 6 and y = -2
sub and find b, the y int
-2 = -3(6) + b
-2 = -18 + b
-2 + 18 = b
16 = b
so ur equation for this line is : y = -3x + 16
(a,7)......so y = 7......" a " is gonna be x
y = -3x + 16
7 = -3x + 16
7 - 16 = -3x
- 9 = -3x
-9/-3 = x
3 = x..........so " a " is gonna be 3 <===
The value of a in the point (a, 7) is 3
The slope intercept equation is as follows:
y = mx + b
where
m = slope
b = y-intercept
Therefore,
Let's find b using (6, -2)
m = -3
y = -3x + b
-2 = -3(6) + b
-2 = -18 + b
b = -2 + 18
b = 16
Therefore,
y = -3x + 16
let's find the value of a in (a, 7)
7 = -3x + 16
7 - 16 = -3x
-9 = -3x
x = -9 / -3
x = 3
Therefore,
a = 3

What does it mean if the determinant of a matrix is 0?
Answers
In linear algebra (university level course), having a determinant of 0 would mean a lot more.
Have an awesome day! :)
Final answer:
The determinant of a matrix is 0 means the matrix is singular, indicating no unique solution for the corresponding system of equations, or in geometry, that space is compressed to a lower dimension.
Explanation:
When the determinant of a matrix is 0, it signals that the matrix does not have an inverse and is considered singular. In practical terms, this means that the system of equations that corresponds to the matrix does not have a unique solution. For instance, in a square matrix, if the determinant is zero, it may indicate that the rows or columns are linearly dependent, meaning that at least one row or column is a scalar multiple of another, resulting in redundant information. In geometry, if we're dealing with transformation matrices, a determinant of zero implies that the transformation compresses the space into a lower dimension, effectively 'flattening' it, and thus, the original geometrical figure loses its volume.

The sum of three numbers is 62. The second number is equal to the first number diminished by 4. The third number is four times the first. What are the numbers? Which three expressions could be used to represent the numbers? n; n - 4; 4n n; 4 - n; n + 4 n; n/4; n + 4
Answers
2nd number = n diminished by 4.....n - 4
3rd number is 4 times the first.....4n
ur 3 expressions are : n , n - 4, 4n <==
Answer:
Numbers: 11, 7 and 44
Expressions: n, n - 4, 4n
Step-by-step explanation:
We have that A + B + C = 62, where A, B and C represent numbers.
We know that the 2nd number (B) is equal to the first number (A), diminished by 4. This means B = A - 4
We also know that the 3rd number (C) is four times the first (A), that is to say 4*A. This means C = 4*A
If we replace this information in the first expression, we have
A + B + C = A + (A - 4) + (4*A) = 62
We change an equation of 3 variables to an equation of just one. Now we solve it putting together the terms that have the variable A:
A + A - 4 + 4*A = 62
2A + 4A - 4 + 4 = 62 + 4
6A = 66
A = 11
Our first number is 11, now we find B and C:
B = A - 4 = 11 - 4 = 7
C = 4A = 4*11 = 44
So, the numbers are 11, 7 and 44
If we change the A for a "n", the expressions that represent the numbers are n, n - 4 and 4n
