Answer: 1,510
Step-by-step explanation: using the formula
(pie•r2•height) - (width•length•height)
I plugged in the numbers to get
(Pie•10(2)•5) - (4•3•5)
This gives you
1,570 - 60
= 1,510

Answer:
B. 9
Step-by-step explanation:
This is probably most easily evaluated by finding f(4) and then g(f(4)).
[tex](g\circ f)(4)=g(f(4))=g(-4^3)=g(-64)\\\\=\left|\\\dfrac{1}{8}\cdot(-64)-1\right|=\left|-\dfrac{64}{8}-1\right|=|-9|\\\\\boxed{(g\circ f)(4)=9}\qquad\textbf{matches B}[/tex]

−3(4 – 3x) = 5x + 16 what is x?
Answer:
x = 7 (i think..)
Step-by-step explanation:
-3 (4 - 3x) = 5x + 16
* multiple -3 to each number in the parenthesis
-12 + 9x = 5x + 16
* add 12 to both sides to cancel it and combine like terms on the other side
9x = 5x + 28
* subtract 5x from both sides to cancel it out and combine like terms
4x = 28
* divide 4 from both sides to get x alone
x = 7
Which expression is NOT equivalent to 56x + 28?
1- 4 ( 14x + 7)

3- (28x + 14) 2

What is the average rate of change of f over the interval -7 < or equal to x
Give an exact number
Answer:
[tex]\frac{4}{3}[/tex]
Step-by-step explanation:
The average rate of change can be found by using the following formula
[tex]\frac{f(x_{2}) - f(x_{1}) }{x_{2} - x_{1}}[/tex]
Since the interval goes from -7 to 2, we should find the y-values that correspond to x=-7 and x=2.
By inspection of the graph, we can clearly see that when x is -7, y is -7 as well and when x is 2, y is 5.
Now that we know this, we can simply plug these values into the formula!
[tex]\frac{f(2) - f(-7) }{2 - (-7)} = \frac{5 - (-7)}{2 - (-7)} = \frac{5 +7}{2+7} = \frac{12}{9} = \frac{4}{3}[/tex]
Good luck!

integer equals 80. Find the unknown
negative integer.
Answer:
-2

or,a^2-5a+2a-10=0
or,a(a-5)+2(a-5)=0
or,(a-5)(a+2)=0
either,
a-5=0
•°•a=5
or,
a+2=0
•°•a=-2(negative integer)
The value of the unknown integer is -2.
What is an expression?Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given data eight times the square of a negative integer plus 24 times the negative integer equals 80 in the form of the mathematical expression will be written as:-
8(-a)²+24-a=80
8a²-24a=80
8a²-24a-80=0
8(a²-3a-10)=0
a²-3a-10=0
a²-(5-2)a-10=0
a²-5a+2a-10=0
a(a-5)+2(a-5)=0
(a-5)(a+2)=0
a-5=0
a=5 or, a+2=0 a=-2
Therefore, the value of the unknown integer is -2.

Grandma Gertrude gave 131313 pieces of jewelry and Grandma Fien gave yyy pieces of jewelry to the Carlson sisters to divide evenly among themselves. There are 555 Carlson sisters. How many pieces of jewelry did each sister receive?
Answer: (13 + y) / 5
Step-by-step explanation:
Since Grandma Gertrude gave 13 pieces of jewelry and Grandma Fien gave y pieces of jewelry to the Carlson sisters, the total jewellery given to the sisters will be:
= 13 + y
Since there are 5 Carlson sisters, the number of pieces of jewelry that each sister receive will be:
= Total jewelries / Number of sisters
= (13 + y) / 5
Answer:Grandma Gertrude gave 131313 pieces of jewelry and Grandma Fien gave yyy pieces, so the sisters received a total of 13+y13+y13, plus, y pieces of jewelry.
The sisters divided the 13+y13+y13, plus, y pieces of jewelry evenly among themselves, and there were 555 sisters. So each sister received \dfrac{13+y}{5}
5
13+y
start fraction, 13, plus, y, divided by, 5, end fraction pieces of jewelry.
Each sister received \dfrac{13+y}{5}
5
13+y
start fraction, 13, plus, y, divided by, 5, end fraction pieces of jewelry.

4(x+6)-3x=26 what is the x value
Answer:
x=2
Step-by-step explanation:
4 (x + 6) - 3x = 26
solve the parenthesis
4x + 24 - 3x = 26
subtract 24 from both sides to get x by itself
4x - 3x = 2
solve
x = 2

12. g(x)= -
13. f(x)= x2
14. k(x) = -2x
guys please help!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
The order of functions from narrowest graph to widest graph is 3x², -x, x² and 2x. A graph is a structure that amounts to a set of items.
What is graph?A graph is a structure that amounts to a set of items in which some combinations of the objects are already in some manner "connected" in discrete mathematics, more specifically within graph theory.
The items are represented by mathematical abstractions known as vertices, and each pair of connected vertices is referred to as an edge. A graph is typically shown diagrammatically as a collection of dots as well as circles representing the vertices and lines or curves representing the edges. The order of functions from narrowest graph to widest graph is 3x², -x, x² and 2x.
Therefore, the order of functions from narrowest graph to widest graph is 3x², -x, x² and 2x.
