greg invested 20 dollars and doubled his money in 4 years. ashley also invested 20 dollars, and after 4 years the amount was equal to 20 to the second power. who had more money after four years?
Answer:
Ashley.
Greg's equation is 20 * 2, which is $40.
Ashley's equation is [tex]20^{2}[/tex], which is 20 * 20, or $400. Ashley's investment is marginally greater than Greg's.
Find f(-2) and g(5)
f(x)=-2x³-5 g(x)=-4x+2
Answer:
f( -2) = 11
g(5) = - 18
Step-by-step explanation:
#1. Solving for f(-2)We're given a function "f" such that when it accepts a variable x, it's output, f(x), is:
[tex] \boxed{ \mathsf{f(x) = - 2 {x}^{3} - 5}}[/tex]
The value of f(x) depends upon what value of x is being inserted.
If x = -2
All the places taken by x will be given to -2
[tex] \implies \mathsf{f( - 2) = - 2( { - 2}^{3} )- 5 }[/tex]
(-2)³ is the cube of (-2) with -8 as it's result
[tex] \implies \mathsf{f( - 2) = - 2( { - 8}^{} )- 5 }[/tex]
when there's no operating sign between two numbers from different origin, they're multiplied
[tex] \implies \mathsf{f( - 2) = 16 - 5 }[/tex]
[tex] \implies \mathsf{f( - 2) = 11 }[/tex]
That gives us the value of f(-2) :
11
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
#2. Solving for g(5):Here's another function, "g", taking x as input and giving us an output g(x), such that:
[tex] \boxed{ \mathsf{g(x) = - 4x + 2}}[/tex]
If x = 5
All the positions taken by x will be given to 5:
[tex] \implies \mathsf{g(5) = - 4(5) + 2}[/tex]
no sign between two numbers from different origin results in their product.
[tex] \implies \mathsf{g(5) = - 20+ 2}[/tex]
[tex] \implies \mathsf{g(5) = - 18}[/tex]
Thus, the value of g(5) is:
-18

The total time that it takes all 5 students ahead of you to receive help from the TA is a random variable. What is the mean of this total time
Okay, So we're given that the amount of time it takes for class one to end is normally distributed. The amount of time it takes for the class to to start is normally distributed. And the amount of time it takes to get from class one to class two is also normally distributed. And they have these normal distributions, I have been down here. X one is the time that it takes to get to The time it takes for the first class to end. X two is the time it takes for the second class to begin. An X three is the time It takes to get from Class 1 to class too. So what I'm gonna do is I'm gonna let t equal X one plus X three and X one plus X three is the time it takes for the first class to end, added to the time it takes to get from class one to class too. So this will be equal to This will be equal to do one of these lines is equal to a normal distribution where we add the main values and we add the variances and this is allowed because all three of these are normally distributed and they're all independent of each other. We can do that when they're independent of each other. So if we add 902-6 minutes we get 908 and if we add one squared to 1.5 squared 1.5 squared is 2 to 5. So this is 3 to 5. And now that we have this normal distribution of the time it takes to get to class two added to the time it takes for the first class to end. We can now set this up With this 3rd distribution. So what we're trying to find is we want this time this normal distribution to be less than at the time it takes for the class to to start. So this normal distribution, so we want t To be less than X two. And so what we're gonna do now is I'm gonna rewrite this by just minus ng ti from both sides. So you get zero Is less than X two -T. And now we can set this up as another normal distribution by minus ng the two means and then we still add the variances. So this would be normal Where we have 908. We're sorry, we have 9 10 minus 98 just to two minutes and we have 3.25 Added to one squared up here. So that is 4.25 as our variants. And now what we can do is just set up a Z score. So right now we want to find the probability that X two minus T is greater than zero, but I'm going to change this. So we've found the probability of Z is greater than 0-. Are you divided by our variance? I'm sorry, our standard deviation and this will let us use then the standard normal distribution table to find our probability. So if we let zero minus you, if we set up this, so we actually find zero minus, you will use to so we know zero minus you is negative two and the standard deviation, It's just the square root of our variance, which is 4-5. So we're trying to find the probability that Z is greater than -2 over the square to 4.25. And we can do this by setting this up a different way, we can say that this is equal to one minus the probability that Z is actually less than or equal to -2 over the square to 4.25. And this will make it. So we can actually look at our distribution table And find the value that we need to, which is the value at -2 divided by the square to 4.25. So if we simplify this further, We'll see that -2 divided by the square Of 4-5, goes to about -97. And now if we go and look at our Normal distribution table, we'll see that the value at negative .97 Is just about .16 60 And so now all we have to do is take one and subtract this value of .1660. And we'll get a resulting value of .834, which is then our probability.

Suppose you have a right triangle called △MNP where ∠N is the right angle. If MN = 6 and MP = 17, which can be used to find m∠P?
arcsin(6/17) can be used to find m∠P in the right angled triangle.
Trigonometric ratioTrigonometric ratio is used to show the relationship between the sides and angles of a right angled triangle.
let m∠P be represented as θ, hence using trigonometric ratio:
sinθ = MN/MP
substituting values:
sinθ = 6/17
θ = sin⁻¹(6/17)
m∠P = sin⁻¹(6/17)
arcsin(6/17) can be used to find m∠P in the right angled triangle.

Step-by-step explanation:
Say triangle A has the angles 30 and 60. triangle b also has those angles. Total angle of any triangle is 180 so 180-60-30 = 90 for triangle A and it is also the same for triangle b. Thus 90 = 90 angles are the same.
in the diagram below, line AB bisects CD at point E. If CD = 13x-15 and EC=5x+9, find the length of EC and the length of CD
Answer:
EC = 64
CD = 128
Step-by-step explanation:
AB bisects CD at E. So, EC = ED
EC + ED = CD
EC + EC = CD
2*(EC) = CD
2* (5x + 9) = 13x - 15
2*5x + 2*9 = 13x - 15
10x + 18 = 13x - 15
Subtract 10x from both sides
18 = 13x - 10x - 15
18 = 3x - 15
Add 15 to both sides
18 + 15 = 3x
33 = 3x
3x = 33
Divide both sides by 3
x =33/3
x = 11
Length of EC = 5x + 9 = 5*11 + 9 = 55 + 9 = 64
CD = 13x - 15 = 13*11 - 15 = 143 - 15 = 128

Find the coordinates of the centroid of the triangle with the vertices at S(-2, 3), T(6, 7), and U(4, 1)
Answer:i cant see the answer
Step-by-step explanation:
The coordinates of the centroid of the triangle with the vertices at S(-2, 3), T(6, 7), and U(4, 1) is G(8/3, 11/3).
What is the centroid of a triangle?The center of the thing is represented by its centroid. The centroid of a triangle is the location where the triangle's three medians connect. The junction of all three medians is another definition for it. The median is a line that connects the middle of a side to the triangle's opposite vertex. The median is divided by the centroid of the triangle in a ratio of 2:1.
How are the coordinates of a centroid found?By averaging the x and y coordinates of each of the three vertices, we can get the centroid of the triangle. Therefore, the centroid formula may be written as G(x, y) = ((x1 + x2 + x3)/3, (y1 + y2 + y3)/3) in mathematics.
How to solve the question?In the question, we are asked to find the coordinates of the centroid of the triangle with vertices at S(-2, 3), T(6, 7), and U(4, 1).
We know that the centroid is found using the centroid formula which is written as G(x, y) = ((x1 + x2 + x3)/3, (y1 + y2 + y3)/3).
Thus, the centroid G = ((-2 + 6 + 4)/3 (3 + 7 + 1)/3),
or, the centroid G = (8/3, 11/3).
Thus, the coordinates of the centroid of the triangle with the vertices at S(-2, 3), T(6, 7), and U(4, 1) is G(8/3, 11/3).

Given y=3x - 4, write an equation that is shifted down 10 and is less steep.
Help pls! Needs to be an equation
Answer:
y = ½x - 14
Step-by-step explanation:
Given the linear equation, y = 3x - 4, where the slope, m = 3, and the y-intercept is (0, -4):
The slope of a linear equation represents the steepness of the line's graph. The higher the value of the slope, the steeper the line. Hence, the slope of the other line must be less than three, but is greater than zero: 0 < m < 3. (a negative slope will show a declining line).
Next, the vertical translation of the line involves changing the value of the parent graph's y-intercept. Since the prompt states that the equation must represent a downward vertical shift of 10 units, then the y-intercept of the other line must be (0, -14).
The linear equation that I have chosen that meets the requirements of the given prompt is: y = ½x - 14. You're more than welcome to choose a different slope, as long as it is less than 3, but is greater than 0 (must be a positive slope).
Attached is a graph of both equations, to demonstrate that the other equation represents a graph with a steeper slope than the original graph.
