Answer:
81
Step-by-step explanation:
Red marbles = r
Black marbles = b
Red : Black
60 : 40
r : b
40r = 60b
r = (60/40)b
Red : Black
4 : 3
r : b + 9
3r = 4(b+9)
3r = 4b + 36
3((60/40)b) = 4b + 36
(9/2)b = 4b + 36
(9/2)b - 4b = 36
(1/2)b = 36
b = 72 This is the original amount of black marbles
They added 9 after this, so
72 + 9 = 81
Suppose that A and B are points on the number line.
If =AB11 and B lies at 9, where could A be located?
Answer: A=-2
Step-by-step explanation:
AB=11
B=9
B-11=A

The value of the function for f(5) is 15,651.
The given function is [tex]f(x)=x^{6}+x^{2} +1[/tex].
We need to find the value of f(5).
What is the function?Functions are the fundamental part of calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x. Mapping or transformation is used to denote a function in math.
Now, put x=5 in the function [tex]f(x)=x^{6}+x^{2} +1[/tex] and simplify.
That is, f(5)=[tex]5^{6} +5^{2} +1[/tex]

What is the obtained value in statistics?The obtained value is the test statistic value derived using the specified statistical procedure.
An outcome of a statistical test of a hypothesis is a test statistic. It displays how closely your actual data match the distribution predicted by the statistical test's null hypothesis.
The p-value of these results, which is needed to decide whether to reject your null hypothesis, is calculated using the test statistic.

Is it possible to have a function f defined on [ 4 , 5 ] and meets the given conditions? f is continuous on [ 4 , 5 ], is non-constant, and takes on only integer values.
No, It is not possible that f is continuous on [ 4 , 5 ] is non-constant, and takes on only integer values.
Here,
A function f defined on [ 4 , 5 ].
We have to find, is it possible to f is continuous on [ 4 , 5 ], is non-constant, and takes on only integer values.
What is Intermediate value theorem?
Intermediate value theorem states that if “f” be a continuous function over a closed interval [a, b] with its domain having values f(a) and f(b) at the endpoints of the interval, then the function takes any value between the values f(a) and f(b) at a point inside the interval.
Now,
A function f defined on [ 4 , 5 ].
Assume that the function,
f : [ 4 , 5 ] → Z is a non constant continuous function.
Then, f(4) and f(5) both are integers and not equal to each other.
By, Intermediate value theorem;
Function f takes all real numbers between f(4) and f(5) at least once.
These would contain all non integers rational and irrational number between f(4) and f(5), contradicting the assumption that function takes only integer values.
Hence, It is not possible that f is continuous on [ 4 , 5 ] is non-constant, and takes on only integer values.

The one time bonus is $40.
Amount earned by Kara per hour is $8.
The range of working hours lies between 16 to 20 hours in a week.
Let 'x' be the number of hours Kara worked.
The the inequality will be;Then, the equation for the amount earned in a week is;
Total pay = one time pay + 8×number of hours
Total pay = one time pay + 8x
The greatest value will be earned by the kara when she will work for 20 hours.
Thus, put x = 20.
Total pay = one time pay + 8×20
Total pay = 40 + 8×20

a) Is the graph linear?
b) What is the domain?
c) What is the range?
d) What are the x and y intercepts?
e) Does the graph have symmetry? Type?
f) What are the extrema and end behavior? 20 points
The Graph is not linear.
To graph f, we graph the equation y = f(x). To this end, we use the techniques outlined in Section 1.2.1. Specifically, we check for intercepts, test for symmetry, and plot additional points as needed. To find the x-intercepts, we set y = 0. Since y = f(x), this means f(x) = 0. f(x) = x2−x−6 0 = x2−x−6 0 = (x−3)(x+2) factor x−3=0 or x+2=0 x = −2,3 So we get (−2,0) and (3,0) as x-intercepts. To find the y-intercept, we set x = 0. Using function notation, this is the same as finding f(0) and f(0) = 02 − 0 − 6 = −6. Thus the y-intercept is (0, −6). As far as symmetry is concerned, we can tell from the intercepts that the graph possesses none of the three symmetries discussed thus far. (You should verify this.) We can make a table analogous to the ones we made in Section 1.2.1, plot the points and connect the dots in a somewhat pleasing fashion to get the graph below on the right. y x f(x) (x, f(x)) −3 6 (−3,6) −2 0 (−2,0) −1 −4 (−1,−4) 0 −6 (0, −6) 1 2 3 4 5 6 7 −3−2−11 2 3 4 1 −6 (1, −6) 2 −4 (2, −4) 3 0 (3, 0) 4 6 (4, 6)

A percentage is a ratio or fraction where the full value is always 100. For example, if Sam received 30% marks in his math test, it signifies that he scored 30 marks out of 100. In ratio form, it is expressed as 30:100 and in fraction form as 30/100.The percentage is used to determine “how much” or “how many.” A percentage number aids in calculating the exact amount or figure that is being discussed. Fractions are compared.This would be true if k=3, but k=2

Answer:
You have a fixed cost ($20) and a variable cost ($2*number of hours you rent the bike)
Cost = Variable Cost + Fixed Cost
Let y = your Cost and x = the number of hours you rent the bike. The fixed cost is $20.
y = ($2 per hour)*(x hours) + $20
