f(x)=3x^3 −2x^2+4x−5
g( x )= 6x− 7
Find (f+g)(x).
Answer:
fx+gx=3x^3-2x^2+10x-12
Step-by-step explanation:
The value of the (f + g)(x) will be (f + g)(x) = 3x³ − 2x² + 10x − 12.
What is a function?Functions are found all across mathematics and are required for the creation of complex relationships.
The functions are given below.
f(x) = 3x³ − 2x² + 4x − 5
g(x) = 6x − 7
Then the value of the (f + g)(x) will be
(f + g)(x) = f(x) + g(x)
(f + g)(x) = 3x³ − 2x² + 4x − 5 + 6x − 7
(f + g)(x) = 3x³ − 2x² + 10x − 12

The math team decided to sell customized pocket protectors as a
fundraiser. These were truly a hot item in our school, and $240 was
raised. Cecily had originally suggested a price that was $2 lower
for each item, but if the team had agreed to that price they would have
had to sell 20 more pocket protectors to get the $240.
How many pocket protectors did they actually sell? What was the price of
each?
Answer:
40

A right rectangular prism has a length of 10 centimeters a width of 2.5 centimeters and a height of 0.9 centimeters what is the volume of the rectangular prism
Answer:
22.5
Step-by-step explanation:
22.5 Cubic centimeters is the volume of the rectangular prism.
What is volume?Volume, which is measured in cubic units, is the 3-dimensional space occupied by matter or encircled by a surface. The cubic meter (m3), a derived unit, is the SI unit of volume. Volume is another word for capacity.
Given, A right rectangular prism has a length of 10 centimeters a width of 2.5 centimeters and a height of 0.9 centimeters
From the general formula of Volume of rectangular prism:
Volume = length * width * height
In our case,
Length = 10 cm
width = 2.5 cm
and height = 0.9 cm
thus, Volume = 10 * 2.5 * 0.9
Volume = 22.5
Therefore, the volume of the given rectangular prism is 22.5 Cubic centimeters.

The sum of two numbers is 133. The difference is 49.
Answer:
The 2 numbers are 42 and 91.
Step-by-step explanation:
Let one number be x, then the other is 133-x.
So as the difference is 49 we have:
133 - x - x = 49
-2x = 49 - 133
-2x = -84
x = -84/-2 = 42.
The numbers are 42 and 133 - 42 = 91.
Answer:
let the numbers be x and y.
x+y=133......(i)
x-y=49.......(ii)
solving eqn (i) and (ii) we get,
x+y=133
x-y=49
we solved it through elimination method.
Here, y and y cancelled out so, we've,
or, 2x=182
so, x=91
now putting value of x in any of the eqn.
in eqn(i)
or, x+y=133
or, 91+y=133
or, y=133-91
so, y=42
Therefore, the two numbers are 91 and 42.

percentage round to 2 decimal "Office and administrative support occupations"; how much more do men earn over females in the same occupation? (Example if a man earned $1200 and a female $1000 than a man earns $200 more. Stated as a percentage a man earns 20% more. ($200/$1000 = 20%).
Answer:
Ok, suppose that a man earns X, and a woman earns Y.
if X is larger than Y, then:
((X - Y)/Y)*100% is the percentage by which the man earns more than the woman. (where Y represents the 100%)
Replacing the given values, we can see that:
X = $1200
Y = $1000
(($1200 - $1000)/$1000)*100% = ($200/$1200)*100% = 0.20*100% = 20%.
If you want the expression only in decimals then you need to ignore the 100% in the equation, and you will have:
(X - Y)/Y
($1200 - $1000)/$1000 = 0.20
This would work for any given values of X and Y.
Other way to see this is:
If the man earns X and the woman Y, then we can see at the quotient:
X/Y
For the previous values we have:
$1200/$1000 = 1.2
This means that the man earns 1.2 times what the woman earns.
If we multiply that by 100%, we have:
1.2*100% = 120%
So the man earns the 120%, which is the 100% that earns the woman plus a 20%, that is what we found before.

Polygon ABCDE rotates 52º about the origin to create polygon
A′B′C′D′E′. If m< BCD = 31º, what is m< B' C' D' ?
Answer:
31°
Step-by-step explanation:
Rotations about the origin are rigid transformations, meaning that they preserve segment length and angle measure. Therefore, since ∠BCD and ∠B'C'D' are corresponding angles, we know that m∠BCD ≅ m∠B'C'D' = 31°.

O AABC AFED by SSS
O AABC to AFED by ASA
Answer:
Option A
..............................................................
ΔABC ≅ ΔFDE by SAS congruence rule.
The correct option is (1).
What are congruent triangles?Congruence is a phrase used frequently in mathematics to refer to a harmonious connection, comprehension, or correlation. A geometric figure is said to be congruent or to be in the relation of congruence if it is feasible to superimpose it on another so that their whole surfaces match. Two triangles are said to be congruent when two sides and their included angles in one triangle are equal to two sides and their included angles in the other.
As per the given data:
In ΔABC :
∠A = 63°
AC = 2.2
In ΔFED :
∠F = 63°
FE = 2.2
By using the distance formula, we can find AB and FD.
From the coordinates, as we can see in the diagram
FD = [tex]\sqrt{(1 - 1)^2 + (4 - 2)^2}[/tex]
= 2 units
Similarly,
AB = [tex]\sqrt{(5 - 5)^2 + (1 - 3)^2}[/tex]
= 2 units
Now from SAS congruence rule:
AB = FD (Both are 2 units)
∠A = ∠F (given)
AC = FE (given)
Hence, ΔABC ≅ ΔFDE by SAS congruence rule.

Step-by-step explanation:
B. (x-4)(4x+1)(x+2)
F. (4x-16)(4x+1)(x+2)
It is always the opposite of what the x intercepts are. So 1 would be -1/4. 2 would be -2 and so one.
The polynomial functions whose x - intercepts are x = 4, -1/4, -2 are -
(x - 4)(4x + 1)(x + 2)
(4x - 16)(4x + 1)(x + 2)
What are polynomial functions?
A polynomial function is a function that involves only non-negative integer powers or only positive integer exponents of a variable in an equation like the quadratic equation, cubic equation, etc.
Given are the polynomial functions whose graphs have x-intercepts at
x = 4, -1/4, -2.
If x = 4, -1/4, -2 represent the x - intercepts of the polynomial functions, than we can say that -
(x - 4) , (x + 1/4) or (4x + 1) , (x + 2) are the factors of the polynomial function.
From the given options, we can see that if we find the x - intercepts of the functions -
(x - 4)(4x + 1)(x + 2)
(x - 4) = 0 or (4x + 1) = 0 or (x + 2) = 0
x = 4, -1/4, -2
and
(4x - 16)(4x + 1)(x + 2)
(4x - 16) = 0 or (4x + 1) = 0 or (x + 2) = 0
x = 4, -1/4, -2
Therefore, the polynomial functions whose x - intercepts are x = 4, -1/4, -2 are -
(x - 4)(4x + 1)(x + 2)
(4x - 16)(4x + 1)(x + 2)

Answer:
g(6) = 71
f(11) = 62
Step-by-step explanation:
Let's solve g(6) first
Plug 6 into x
g(6) = 2(6)^2 - 1
g(6) = 2(36) - 1
g(6) = 72 - 1
g(6) = 71
Now let's solve f(11)
f(11) = 5(11) + 7
f(11) = 55 + 7
f(11) = 62
Thus, out answers are 71 and 62 respectively
