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.

Given the definitions of f(x) and g(x) below, find the value of f(g(-1)).
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 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]

Multiple choice answer
Answer:
C. 9.24
Step-by-step explanation:
x is the height here, looking at the triangle.
To find x, however, we first have to find the hypotenuse. To formula for that is b (side we know)/cos(α) (angle we know). Substitute b for 6, and α for 57.
6/cos(57) would equal about 11.0647.
Now back to x. To figure that out, subtract 6² from 11.01647². Then, find the square root of that.
x = √11.01647² - 6²
x = √121.3626112609 - 36
x = √85.3626112609
x = 9.23918888544335
x ≈ 9.24, so C is the answer.

Let the number be x
Mar halves the number becomes = x x 1/2 to get 53.2
The equation to solve this problem is x/ 2 = 53.2
Such that to find x
x/2= 53.2
x = 2 x 53.2= 106.4
The number is 106.4

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
