Answer:
Step-by-step explanation:
first arrange the data from ascending to descending order
since they are already in the order we dont need to change
first quartile(Q1)=(N+1)/4
=7+1/4
=8/4
=2 nd term
=43
second quartile(Q2 or median)=(N+1)/2
=7+1/2
=8/2
=4 th term
=44
third quartile(Q3)=3(N+1)/4
=3(7+1)/4
=3*8/4
=24/4
=6 th term
=49
Which statement is true of this graphed function?
Answer:
f(x) -0 over the interval (-, -4)
Step-by-step explanation:
Describe how the graph of y= x2 can be transformed to the graph of the given equation. (2 points) y = (x-4)2-8
Answer:
The description is that the function was translated 4 units to the right and 8 units down.
Step-by-step explanation:
Translations:
Translating a function f(x) a units to the right is the same as finding f(x - a).
Translating a function f(x) a units to the left is the same as finding f(x + a).
Translating a function f(x) a units up is the same as finding f(x) + a.
Translating a function f(x) a units down is the same as finding f(x) - a.
y= x² to y = (x-4)²-8
First at the domain, x becomes x - 4, so f(x) becomes f(x - 4), that is, the function was translated 4 units to the right.
Then the function is subtracted by 8, that is, it was translated 8 units down.
The description is that the function was translated 4 units to the right and 8 units down.

Find the 13th term of the geometric sequence 3 -15 75
Answer:
732,421,875
Step-by-step explanation:
You have to find the pattern which in this case is just multiplying by 5 every absolute number. the negatives are only every other one. from knowing this you just have to find all the numbers until 13 and the 13th term in this sequence is 732,421,875
What is the length of side a? Round to the nearest tenth of an inch. Enter your answer in the box.
16 in.
a
7 in.
Please show work. What is the volume of the figure?
Answer:
Volume = 288 in.³
Step-by-step explanation:
Volume of the solid = volume of the cube + volume of the square pyramid
V = a³ + ⅓*a²*h
a = 6 in.
h = 12 - 6 = 6 in.
Plug in the values into the volume formula
Volume = 6³ + ⅓*6²*6
Volume = 216 + 72
Volume = 288 in.³
A cuboid with a volume of 924 cm^3 has dimensions
4 cm, (x + 1) cm and (x + 11) cm.
Find the longest length of the Cuboid.
Answer:
21
Step-by-step explanation:
Volume of a cuboid is given by
V = l*w*h
924 = 4 (x+1) (x+11)
FOIL
924 = 4(x^2 +11x+x+11)
924 = 4(x^2+12x+11)
Divide each side by 4
231 = (x^2+12x+11)
Subtract 231 from each side
0 = x^2 +12x +11-231
0 = x^2 +12x - 220
Factor
0 = (x+22) (x-10)
Using the zero product property
x+22 =0 x-10 =0
x=-22 x=10
We cannot have a negative length
x=10
The side lengths are 4, 10+1, 10+11
4,11,21
The longest is 21

F: 3x(3x) = 9x²
O: 3x(1) = 3x
I: 3x(1) = 3x
L: 1(1) = 1
combine the 'like terms' in the middle to get 6x

the answer is B. 9x^2 + 6x+1
PLEASE HELP 15 POINTS,
It is now time to complete the Utilities Discussion. Research the cost of some sort of household bill. Examples are natural gas, electricity, water, etc. Find one that models a linear function and write a function to represent the cost of this utility.
Explain how you found your information and wrote your function. Be sure to define your variables, use function notation.
Step-by-step explanation:
I take gas consumption as example.
Consider the followings,
Let M be the gas meter reading per month
A be the fuel adjustment fee
B be monthly maintenance fee
Y be unit cost per Joule
Let X be monthly bill
( 1 meter reading unit = 48 unit of Joule )
Monthly bill payment :
X = Mx48xY + A + B
in function notation, the monthly bill is f(M, Y, A, C)

Step-by-step explanation:
In any right triangle, the following is true:
The sine of any angle is equal to its opposite side divided by the hypotenuse of the triangle. (o/h)
The cosines of any angle is equal to its adjacent side divided by the hypotenuse. (a/h)
The tangent of any angle is equal to its opposite side divided by its adjacent side. (o/a)

Which equation represents a function of x that is not linear?
Answer:
y = 4x+3x^2
Step-by-step explanation:
For an equation to be linear, x must have a power of 1
y = 4x+3x^2 has a power of x that is not x ( x^2) so this is not linear ( it is quadratic)
