set whether each of the following equations represents a growth or decay
1. f(x)= 3[tex]^{x}[/tex]
2.f(x) = (0.25)[tex]x^{x}[/tex]
3.f(x)= [tex]\frac{2}{3x^{x} }[/tex]
4.f(x) =[tex]\frac{3}{2} x^{x}[/tex]
Answer:
Notice that the written functions are mostly incorrectly written, after a short online search i've found the correct ones, which are the ones i will write in this answer.
A general exponential equation can be written as:
f(x) = A*(r)^x
Where A is the initial value, r is the rate of growth, and x is our variable.
If r > 1, the function represents a growth.
if 0 < r < 1, the function represents a decay.
1) f(x) = 3^x
Here we have r = 3
This is clearly larger than 1, then this function represents a growth.
2) f(x) = (0.25)^x
Here we have r = 0.25, which is smaller than 1 and larger than zero, then this function represents a decay.
3) f(x) = (2/3)^x
here we have r = 2/3 = 0.66
This is larger than zero and smaller than 1, then this function represents a decay.
4) f(x) = (3/2)^x
Here we have r = 3/2 = 1.5
This is larger than 1, then this function represents a growth,

If the terminal side of angle θ goes through the point (−313√13,−213√13) on the unit circle, then what is cos(θ)?
Answer
cos(θ) = –313√(13)
Step-by-step explanation:
There is a rule we are to establish first to get the answer right.
If the terminal side of an angle θ in standard position intersects a unit circle A(x, y), then cos(θ) = x and sin(θ) = y.
Therefore, given that the terminal side of angle θ goes through the point (−313√13,−213√13) on the unit circle:
cos(θ) = –313√(13)
Find the smallest value of m such that the LCM of m and 34 is 374.
Answer:
11
first you use a number tree
34 374
/\ /\
2 17 2 187
/\
11 17
express the numbers in prime factors
374=2×11×17
34 =2×17
in finding LCM you use the highest prime factors in this case the highest prime factors are 2, 11 and 17
So m factors are 2 and 11
which means m is 2×11=22
22 in its smallest form is 11

which pair of these points defines a line with a slope 2/3? A. (2, 6) and (3, 0) B. (6, 2) and 3, 0) C. (6, 2) and (0, 0) D. (2, 6) and (0, 0)
Answer:
B. (6,2) and (3,0)
Step-by-step explanation:
To find the slope the equation is [tex]\frac{y_{2-y_{1} } }{x_{2} -x_{1} }[/tex] so for (6,2) and (3,0) the equation would look like this [tex]\frac{0-2}{3-6}[/tex] which simplies down to [tex]\frac{-2}{-3}[/tex] and a negative divided by a negative is a positive so you're slope is [tex]\frac{2}{3}[/tex] and it matches the question.

WHOEVER ANSWERS IS CONSIDERED THE BRAINLIEST QUESTION: Faye has a bag that contains 10 red, 13 blue, 16 white, 10 green, and 11 black marbles. She pulls a marble out of the bag without looking. What is the probability Faye pulls out a white marble.
SHOW WORK!
Answer:
Faye's probability of pulling out a white marble is 3/80.
Step-by-step explanation:
To find the probability, we must first add everything up. 10 + 13 + 16 + 10 + 11 = 60 marbles. Now we divide 60 by the amount of white marbles there are. 60 ÷ 16 = 3.75% or 3/80. Therefore, the probability of Faye pulling out a white marble is 3/80.

Which of the following is most likely the next step in the series?
Answer:
Option A is the next step in the series.
The sum of two numbers is 59 and the difference is 11
Answer:
35 and 24
Step-by-step explanation:
35 + 24 = 59
35 - 24 = 11
Answer:
24 and 35
Step-by-step explanation:
x + y = 59
x - y = 11, then x = y + 11
substitute for x:
y + 11 + y = 59
simplify:
2y + 11 = 59
subtract 11 from each side of the equation:
2y = 48
divide both sides by 2:
y = 24
x = 35

A piggy bank contains six times as many quarters as dimes. If the total amount of money
is $28.80, how many quarters and dimes are in the piggy bank?
9514 1404 393
Answer:
108 quarters18 dimesStep-by-step explanation:
A group of 6 quarters and 1 dime has a value of $1.60. Then there are ...
$28.80/$1.60 = 18
groups like that in the piggy bank.
The number of quarters is 18×6 = 108.
The number of dimes is 18×1 = 18.
There are 108 quarters and 18 dimes in the piggy bank.

This is a 30 - 60 - 90 degree special right triangle
We know this because in these types of triangle the hypotenuse is equal to twice the short leg
[tex]\sqrt{3} *2=2\sqrt{3}[/tex]
to calculate the missing side length (which is the long leg)
we multiply the short leg by [tex]\sqrt{3}[/tex]
[tex]\sqrt{3} *\sqrt{3} =3[/tex]
so the missing side length is 3

Ms.Carmine is making a necklace using small beads. For every red bead that she uses, she adds 6 black beads and 9 green beads. If she used 48 black beads, how many red beads and how many green beads does Ms.Carmine use?
Answer:
8 red beads, 72 green beads
Step-by-step explanation:
1 = x
6 = 48
9 = x
to get from 6 to 48 you multiply by 8 so do that for 1 and 9 to get the answer
1 · 8 = 8
9 · 8 = 72, 72+8 = 80
Nadia swims at a rate of 50 meters per minute. Create a function f, where f(n) gives the number of meters Nadia swims given the number of minutes she swims, n. Write the appropriate variable and symbol to correctly complete the equation for the function.
f(n) = 50 ________ ________
The function is f(n)=50n, where f(n) gives the number of meters, Nadia swims given the number of minutes she swims.
What is a function?The function is defined as a mathematical expression that defines a relationship between one variable and another variable.
We are given the function f, where f(n) is the number of meters Nadia swims given the number of minutes she swims, n, can be written as ;
f(n)=50n.
This function that represents a linear relationship, where the output (the number of meters Nadia swims) is directly proportional to the input (the number of minutes she swims).
Therefore if Nadia swims for 10 minutes, the function will output 500 meters;
10 minutes x 50 meters/minute = 500 meters
Thus, the required function is;
f(n)=50n.
