f(x) = 4x + 14
g(x) = 3x2 + 5x – 6
Answer:
-18
Step-by-step explanation:
[tex]f(x) = 4x+14\\g(x) = 3x^{2} + 5x -6\\f(g(x)) = 4(3x^{2} + 5x -6)+14 \\f(g(-1)) = 4(3(-1 ^{2}) + 5(-1) -6) +14 \\\\= 4(3 - 5 - 6) + 14\\= 4 (-8) + 14\\= - 32 + 14 \\= -18[/tex]

An event organizer found that 70% of young couples prefer to have indoor weddings instead of outdoor weddings. You want to survey three randomly chosen couples and use the results to find the estimated probability that all three couples prefer indoor weddings.
This scenario can be simulated by generating a set of three numbers using a number generator with numbers
. The numbers
would represent couples who prefer indoor weddings. If all three numbers in the set are in the range
, it would mean that all three couples prefer indoor weddings.
Answer:
1. 0-9
2. 0-6
3. 0-6
Step-by-step explanation:
This scenario can be simulated by generating a set of three numbers using a number generator with numbers 0-9. The numbers 0-6 would represent couples who prefer indoor weddings. If all three numbers in the set are in the range 0-6, it would mean that all three couples prefer indoor weddings.

An online shopping club has 13000 members when it charges $7 per month for membership. For each $ monthly increase in membership fee, the club loses approximately 500 of its existing members. Write and simplify a function R to represent the monthly revenue received by the club when x represents the price increase.
Hint: Monthly revenue = # members•monthly fee
Just a answer with work will do, ill brainliest the best one.
Answer:
The function is: [tex]R(x)=(13000-500x)[/tex] × [tex](7 + x)[/tex]
Step-by-step explanation:
Total members=13000
Membership charge per month=$7
Increase in Membership charge per month=$1
For each $1 monthly increase in membership fee, the club loses approximately=500 members
For 1 month, 1 dollar decrease is 500 × 1
For x months, the decrease in the members is 500 × [tex]x[/tex] =[tex]500x[/tex]
The increase in membership fee is 7 + [tex]x[/tex]
After that,
Monthly revenue = Number of members × Monthly fee
Monthly revenue = [tex](13000-500x)[/tex] × [tex](7 + x)[/tex]
[tex]R(x)=(13000-500x)[/tex] × [tex](7 + x)[/tex]

Answer: B -4
Step-by-step explanation:
Value of coefficient of the squared term in the parabola's equation = -4
Correct option is B.
What is parabola?A parabola is a U-shaped plane curve where any point is at an equal distance from a fixed point (known as the focus) and from a fixed straight line which is known as the directrix.
Given,
Vertex of parabola (h,k) = (3, 5)
y = 6 for x = -1
Parabola opens horizontally left side
Vertex-form equation of parabola
x = a(y - k)² + h
-1 = a(6 - 5)² + 3
-1 = a(1) 3
a = -4
Hence, -4 is value of coefficient of the squared term in the parabola's equation.

A child tosses a baseball up into the air. On its way down, it gets caught in a tree for several seconds before falling down to the ground.

(image included)
Answer:
most likely asking for something like this
Step-by-step explanation:
Answer:
Read the step-by-step for the entire answer!!!
Step-by-step explanation:
Whenever you have situations like these you have to look at it from the perspective given.
If you are throwing a ball it's going to start at ground 0 where the child is, therefore the height of the child is how high off the ground the ball is at 0 seconds.
If it is thrown, and it is stuck in the tree for a few seconds, then that means on the graph you will see an incline of the graph, and then a stale line for a few seconds as the ball is stuck in the same height for a few seconds.
After the ball falls down, then so will the height of the ball.
t - a function of time, is always on the x-axis because time variables are usually on the x-axis of a graph.
I choose seconds as a measurement of time because in a realistic situation a ball will be in the air for seconds.
h - the height of the ball, will be on the y-axis of the graph because it is a dependent variable (i.e. the height of the ball is dependent on how long the ball is in the air for).
The image below is the graph.

Identify the following for the exponential function y = 5(1/4)x.
a. Growth or decay?
b. Initial value
c. Growth/decay factor
d. Growth/decay rate (as a percentage)
Answer:
A)
Decay
B)
Initial value is 5.
C)
The decay factor is 0.75.
D)
75%
Step-by-step explanation:
An exponential function is given by:
[tex]f(x)=a(r)^x[/tex]
Where a is the initial value and r is the rate.
We have the function:
[tex]y=5(1/4)^x[/tex]
So, a = 5 and r = 1/4.
A)
Remember the guidelines:
It is exponential growth if r > 1. And it is exponential decay if r < 1. (And r must be positive.)Our rate is 1/4 or 0.25.
It is less than 1, so our function is exponential decay.
B)
The initial value is the value in front of our rate.
So, our initial value in this case is 5.
C)
The decay factor will be 1 - r, where r is our rate.
Since our rate is 0.25, our decay factor is 1 - 0.25 = 0.75.
So, we are decaying by a factor of 0.75.
D)
To convert a decimal to a percent, we move the decimal dot two places to the rght and add a percent sign.
So, 0.75 will be 75.0 % or smply 75%.
It is a 75% decay.
