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.

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

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.

Thank you.

Option A

..............................................................

ΔABC ≅ ΔFDE by SAS congruence rule.

The correct option is (1).

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.

Answer:

22.5

Step-by-step explanation:

22.5 Cubic centimeters is the volume of the rectangular prism.

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.

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.

Answer: B and F

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)

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
