Explain how you know that 0.38 is a rational number?
Answer:
0.38 is a rational number because it can be expressed as fraction, and it isn't a repeating decimal.
Step-by-step explanation:
Repeating decimals aren't rational, and all rational numbers can be expressed as a fraction, or they aren't rational.
It's a rational number because it stops, the decimal is irrational if it continues forever without a pattern
Vector u has its initial Point at (15,22) and it’s terminal point at (5,-4)
Final answer:
The position vector of vector u is (-10, -26). The magnitude of vector u is sqrt(776). The direction of vector u is 68.2 degrees.
Explanation:
The position vector of vector u can be found by subtracting the initial point from the terminal point. So, the position vector of u is (5-15, -4-22) = (-10, -26).
The magnitude of vector u can be found using the distance formula, which calculates the length of a vector. The formula is: magnitude = sqrt(x^2 + y^2), where x and y are the components of the vector. So, for vector u, the magnitude is: sqrt((-10)^2 + (-26)^2) = sqrt(100 + 676) = sqrt(776).
The direction of vector u can be found using trigonometry. The direction angle (theta) is given by tan(theta) = y/x. So, for vector u, the direction angle is: tan(theta) = (-26)/(-10) = 2.6. Converting to degrees, theta = arctan(2.6) = 68.2 degrees.

What are the vertical and horizontal asymptotes for the function 3x^2/x^2-4
Answer: vertical asymptotes: x = 2, x = -2
horizontal asyptote: y = 3
Step-by-step explanation:
[tex]\dfrac{3x^2}{x^2-4}[/tex]
Vertical Asymptotes are the restrictions on "x", which is denoted by the denominator being unequal to zero.
x² - 4 = 0
(x + 2)(x - 2) = 0
x + 2 = 0 and x - 2 = 0
x = -2 and x = -2
Horizontal Asymptotes are determined by the degree of the numerator (n) compared to the degree of the denominator (m) as follows:
If n > m , then no horizontal asymptote (use long division to find slant asymptote)If n = m , then horizontal asymptote is coefficient of n divided by coefficient of mIf n < m , then horizontal asymptote is: y = 0In the given problem, the degree of both the numerator and denominator is 2 so horizontal asymptote is: [tex]y = \dfrac{3}{1} = 3[/tex]

Step-by-step explanation:
Genevieve collected pledges of $3.50 for every complete mile she runs in a charity race. Her goal is to raise at least $50.00. Genevieve wrote the inequality 3.5m ≥ 50 to find out how many miles she needs to run.
Genevieve thinks she needs to run at least 14 miles.
But Carla says Genevieve needs to run more miles than that.
Who is correct and why?
A.
Carla is correct because 3.5 × 14 is less than 50.
B.
Genevieve is correct because 3.5 × 14 is about 50.
C.
Carla is correct because 3.5 × 14 is not equal to 50.
D.
Genevieve is correct because 3.5 × 14 is greater than 50.
Answer:
A.
Carla is correct because 3.5 × 14 is less than 50.
Step-by-step explanation:
3.5m ≥ 50
To determine how many miles she needs to run, divide each side by 3.5
3.5m/3.5 3.5m ≥ 50 50/3.5
m ≥ 14.28571429
She must run more than 14 miles
Carla is correct because 14* 3.5 = 49. That is less than the 50 she wants to raise.
Solve by elimination. 4x-y=6 3x+2y=21
Answer:
x=3, y=6
Step-by-step explanation:
4x-y =6
3x+2y = 21
To use elimination we will multiply the first equation by 2
2(4x-y) =6*2
8x -2y =12
We will add this equation to the second equation to eliminate y
8x -2y =12
3x+2y = 21
-----------------
11x = 33
Divide each side by 11
11x/11 = 33/11
x =3
We still need to solve for y
3x+2y = 21
Substituting x=3
3*3+2y = 21
9+2y =21
Subtract 9 from each side
9-9+2y = 21-9
2y = 12
2y/2 = 12/2
y =6
In which equation is the constant of proportionality 5?
a. x = 5y
b. y = 5x
c. 6 = x + 5
d. 6 = 5 - x

Bob raked 5% more leaves than Adam raked. Bob raked 357 liters of leaves. How many liters did Adam rake?
Answer:
Adam raked 340 liters
Step-by-step explanation:
Bob raked more leaves than Adam
5% more means take 100 % and add 5% = 105%
105% as a decimal is 1.05
Bob = 1.05 * Adam
We know Bob raked 357
357 = 1.05 Adam
Divide by 1.05
357/1.05 =1.05/1.05 Adam
340 = Adam
I need help with #7 ?!!!
Btw #6 is correct
Choice C for problem 6 is correct. The two angles (65 and 25) add to 90 degrees, proving they are complementary angles.
===========================================
The answer to problem 7 is also choice C and here's why
To find the midpoint, we add up the x coordinates and divide by 2. The two points A(-5,3) and B(3,3) have x coordinates of -5 and 3 respectively. They add to -5+3 = -2 which cuts in half to get -1. This means C has to be the answer as it's the only choice with x = -1 as an x coordinate.
Let's keep going to find the y coordinate of the midpoint. The points A(-5,3) and B(3,3) have y coordinates of y = 3 and y = 3, they add to 3+3 = 6 which cuts in half to get 3. The midpoint has the same y coordinate as the other two points
So that is why the midpoint is (-1,3)

Answer:
y= 5x + 3
Step-by-step explanation:
This is because you solve for slope, which is 5, then plug that into point slope form to get:
y - 8 = 5(x - 1)
y - 8 = 5x - 5
y = 5x + 3.
Answer:
y = 5x + 3
Step-by-step explanation:
Step 1. Find the slope
Each time x increases by 1 unit, y increases by 5 units.
m = slope = 5/1 = 5
Step 2. Find the y-intercept.
y = mx + b
When x = 4, y = 23.
23 = 5×4 + b
23 = 20 +b
b = 3
y = 5x + 3
The graph is a straight line with slope m = 5 and a y-intercept at y = 3.

What are coordinates?A pair of numbers called coordinates are used to locate a point or a form in a two-dimensional plane. The x-coordinate and the y-coordinate are two numbers that define a point's location on a 2D plane.
Given, A graph where we can see a Graph of a triangle XYZ that transforms to become x'y'z'.
Since the given graph is transformed not scaled.
Thus, the dimension will be the same and we can justify the means by just Calculating for one point.
For Point x:
Original coordinates os x = (0, 0)
coordinates of the x after transformation = (3, -1)
Thus,
horizontal displacement in X = +3
vertical displacement in X = -1
therefore, (x, y) → (x + 3, y − 1) is the algebraic rule that describes the transformation.

How do you solve:
3(a+2)=2(a-7) and 9(t-1)=6(t+2)-t
Answer:
t=3
Step-by-step explanation:
Simplifying
5 + -1(t + 3) = -1 + 2(t + -3) Reorder the terms:
5 + -1(3 + t) = -1 + 2(t + -3)
5 + (3 * -1 + t * -1) = -1 + 2(t + -3)
5 + (-3 + -1t) = -1 + 2(t + -3)
Combine like terms: 5 + -3 = 2
2 + -1t = -1 + 2(t + -3)
Reorder the terms:
2 + -1t = -1 + 2(-3 + t)
2 + -1t = -1 + (-3 * 2 + t * 2)
2 + -1t = -1 + (-6 + 2t)
Combine like terms: -1 + -6 = -7
2 + -1t = -7 + 2t
Solving
2 + -1t = -7 + 2t
Solving for variable 't'.
Move all terms containing t to the left, all other terms to the right.
Add '-2t' to each side of the equation.
2 + -1t + -2t = -7 + 2t + -2t
Combine like terms: -1t + -2t = -3t
2 + -3t = -7 + 2t + -2t
Combine like terms: 2t + -2t = 0
2 + -3t = -7 + 0
2 + -3t = -7
Add '-2' to each side of the equation.
2 + -2 + -3t = -7 + -2
Combine like terms: 2 + -2 = 0
0 + -3t = -7 + -2
-3t = -7 + -2
Combine like terms: -7 + -2 = -9
-3t = -9
Divide each side by '-3'.
t = 3
Simplifying
t = 3

Answer:
[tex]m\angle M=90[/tex]
[tex]m\angle A=63[/tex]
[tex]m\angle N=27[/tex]
[tex]\Delta MAN[/tex] is a right triangle.
Step-by-step explanation:
Since we know that sum of all angles of triangles equals to 180 degrees.
To find the measure of our given angles we will have to find the value of x. The value of x can be found by equating the measure of all angles of our given triangle with 180.
[tex]4x-5+9x-9+10x+10=180[/tex]
[tex]23x-14+10=180[/tex]
[tex]23x-4=180[/tex]
[tex]23x=180+4[/tex]
[tex]23x=184[/tex]
[tex]x=\frac{184}{23}[/tex]
[tex]x=8[/tex]
Now let us find measure of each angle by substituting value of x in given expressions.
[tex]m\angle M=10*x+10[/tex]
[tex]m\angle M=10*8+10[/tex]
[tex]m\angle M=80+10[/tex]
[tex]m\angle M=90[/tex]
Therefore, measure of angle M is 90 degrees.
[tex]m\angle A=9*x-9[/tex]
[tex]m\angle A=9*8-9[/tex]
[tex]m\angle A=72-9[/tex]
[tex]m\angle A=63[/tex]
Therefore, measure of angle A is 63 degrees.
[tex]m\angle N=4*x-5[/tex]
[tex]m\angle N=4*8-5[/tex]
[tex]m\angle N=32-5[/tex]
[tex]m\angle N=27[/tex]
Therefore, measure of angle N is 27 degrees.
From the measures of angles we can say that triangle MAN is a right triangle.
