Brittany and four of her friends want to join a softball league. The league requires teams to have at least nine players, but teams cannot have more than eighteen players. In interval notation, how many more people can join Brittany's team?
The additional number of people is [4, 13]
How to determine the number of people?Brittany and four of her friends are five people.
So, we have:
n = 5
The conditions are given as
At least = 9At most = 18Let the additional number of people be x
So, we have the following inequalities
x + 5 ≥ 9 and x + 5 ≤ 18
Subtract 5 from both sides
x ≥ 4 and x ≤ 13
Express as interval notation
[4, 13]
Hence, the additional number of people is [4, 13]

For easy estimation, option A = nearest hundred,B = nearest ten, C = nearest hundred and D= nearest thousand.
Calculation of numbers using east estimations3529 and 3689
3529 to the nearest hundred = 3500 and,

find the inverse of
f(x) = -6xˆ2 + 24x - 100
Answer:
See below
Step-by-step explanation:
y = -6x^2 + 24x-100
solve for 'x'
y + 100 = -6x^2 + 24x = -6(x^2-4x) complete the square for x
(y+100) /(-6 ) = (x-2)^2 -4 add 4 to both sides
(y+100)/(-6) +4 = (x-2)^2 sqrt both sides
sqrt [ ( y+100)/(-6) + 4 ] + 2 = x change x and y
y = ± sqrt [ (x+100)/(-6) + 4 ] + 2 simplify (if needed)
y = ± sqrt( -x/6 -12.666) + 2
Choose the function that shows the correct transformation of the quadratic function shifted eight units to the left and one unit down.
ƒ( x) = ( x + 8) 2 + 1
ƒ( x) = ( x - 8) 2 + 1
ƒ( x) = ( x + 8) 2 - 1
ƒ( x) = ( x - 8) 2 - 1
we conclude that the correct option or the translated function is the last one.
f(x) = (x - 8)² - 1
Which is the correct equation for the transformed function?The parent quadratic function is:
y = g(x) = x²
If we translate this function 8 units to the left, then we will have the new function:
f(x) = g(x - 8)
And if now we translate this function one unit downwards, we will get:
f(x) = g(x - 8) - 1
Now we can replace g(x) by the parent quadratic function we willl get:
f(x) = (x - 8)² - 1
From this, we conclude that the correct option is the last one.

In fig. 6.39, side QP and RQ of ΔPQR are produced to points S and T respectively, if ∠SPR = 135° and ∠PQT = 110°, find ∠PRQ.
Answer:
PRQ = 65 degrees
Step-by-step explanation:
Angles SPR and QPR and angles TQP and RQP form linear pairs, so they are supplementary (angle measures add up to 180 degrees).
SPR + QPR = 180
135 + QPR = 180
QPR = 45
TQP + RQP = 180
110 + RQP = 180
RQP = 70
Since interior angles of a triangle add up to 180 ...
QPR + RQP + PRQ = 180
45 + 70 + PRQ = 180
PRQ = 65

Area of a triangle
In order to determine the area of a triangle, we have to know the size of the base and the size of the height
The formula for finding the area of a triangle is given as = half the base multiplied by the height
In mathematical form, it is written as;
Area = 1/ 2 × base × height
From the figure given, we have their lengths to be'
base = 57. 2 m
height = 19. 5 m
Let's substitute the values
Area = 1/ 2 × 57. 2 × 19. 5
Area = 1/ 2 × 1115. 4

Which expression gives the total amount Harmony has earned in her first n years of her career?
Answer:
42000*1.04^(n-1)
Step-by-step explanation:
4% is equal to 0.04, a raise is 1+0.04=1.04
1.04 is now the number we are multiplying by to get a new yearly salary for Harmony.
42000*1.04^(n-1) since n is how many years after she has the job you have to raise it to the power and subtract one.

The domain of a function is the set of inputs that we can use on the function, and the range is the set of outputs.
a) f(x) = -2x
This is just a linear equation, as you can see, for no value of x we have a problem, then the domain is the set of all real numbers.
Similar for the range, it covers the set of all real numbers, then:
domain: set of all real numbers.range: set of all real numbers.b) g(x) = 0.5*x² + 5
This is a quadratic function, so the domain is the set of all real numbers again.
Now the range will have a minimum, which is at the vertex of the parabola.
For the parabola the vertex is at x = 0:
g(0) = 0.5*0² + 5 = 5
