Express your answer as a polynomial in standard form. f(x) = -x + 3 g(x) = 2x^2 – 3x - 7 Find: f(g(x))​

Answer:

Yes.

Here’s an easy (and cheap) one:  [tex]\\\\\sqrt 2\\-\sqrt 2[/tex]

In fact, I can find a formula for them.

The two numbers will always be of the form:

[tex]x_1 =a+b\sqrt c \\x_2 =a-b\sqrt c \\[/tex]

A and B are rational

C is rational and not a perfect square of a rational number

These are irrational because the square root will not resolve to a rational number.

12=(+√)(−√)=2−(√)2=2−2 . Looks rational to me.

1+2=+√+−√=2 , which also is rational.

Hope this helped!

Answer:

See under for the sequence

Step-by-step explanation:

The term with -X⁴ comes first because 4 is the highest power of x.

Then comes 7x³y³ because 3 is the second highest power

Then 2x²y⁴ because 2 comes next

Then -3xy⁵ because x is raised to 1 power which is the lowest

Answer:

[tex]\large\boxed{75.4cm(1 d.p)}[/tex]

Step-by-step explanation:

Important Information:

Circumference of a cirlce= [tex]\pi*diameter[/tex]

Diameter= [tex]2*radius[/tex]

Method:

The first step in working out the circumference of this cirlce is to work out the diameter. You can work this out by multiplying the radius of 12 by 2, this gives you 24cm. This is because the radius is half of the diameter.

The next step is to work out the circumference. You can do this by multiplying pi by the diameter of 24, this gives you [tex]27\pi[/tex] or 75.4cm (1 d.p).

Step by Step:

1) Multiply 12 by 2.

[tex]12*2=24cm[/tex]

2) Multiply pi by 24.

[tex]\pi*24=75.4cm(1 d.p)[/tex]

Answer:

[tex]\approx 45.1\:\mathrm{w/\: some \: MOE}[/tex]

Step-by-step explanation:

The area of [tex]ABCD[/tex] is comprised of two triangles, so we can find the area of both triangles and add them to get the total area of

Since the sum of the interior angles of a triangle add up to [tex]180^{\circ}[/tex], we have:

[tex]\angle C=180-44-38=\fbox{$98^{\circ}$}[/tex].

The Law of Sines is given as:

[tex]\frac{\sin A}{a}=\frac{\sin B}{b}=\frac{\sin C}{c}[/tex] for any triangle.

Therefore, we have the proportion:

[tex]\frac{\sin 98^{\circ}}{10}=\frac{\sin 44^{\circ}}{BC},\\BC=\frac{10\cdot \sin 44^{\circ}}{\sin 98^{\circ}},\\BC\approx 7.01[/tex].

Now that we have two sides of a triangle and the angle between them, we can use [tex][\triangle]=\frac{1}{2}ab\sin C[/tex]  to find the area of [tex]\triangle CBD[/tex]:

[tex][CBD]=\frac{1}{2}\cdot 10\cdot 7.01 \cdot \sin 38^{\circ},\\\\\left [CBD]\right\approx 21.58[/tex].

Since [tex]\triangle ABD[/tex] is a right triangle, we can use basic trig rules for a right triangle to solve for the sides:

[tex]\sin 55^{\circ}=\frac{AB}{10},\\AB=10\sin 55^{\circ},\\AB\approx 8.19[/tex],

[tex]\sin 35^{\circ}=\frac{AD}{10},\\AD=10\sin 35^{\circ},\\AD\approx 5.74[/tex].

Therefore, the area of [tex]\triangle ABD[/tex] is:

[tex]\frac{1}{2}\cdot 8.19\cdot 5.74\approx 23.49[/tex].

The area of [tex]ABCD[/tex] is then

[tex]21.58+23.49=45.07=\fbox{$45.1$}[/tex].

[tex]\bigstar[/tex] Note that intermediate results were rounded during this calculation. Therefore, there is a small margin of error when rounding to final answer to one decimal place. I recommend plugging in values for yourself using all equations I wrote above, then rounding only your final answer to one decimal place as requested by the problem.

Answer:

Graph F best represents the function.

The correct graph F is also attached below.

Step-by-step explanation:

Given the function

f(x) = 2(5)ˣ

We know that the value of the y-intercept can be determined by setting x = 0 and determining the corresponding value of y.

so substituting x = 0 in the function

y = 2(5)ˣ

y = 2(5)⁰

y = 2(1)      ∵ (5)⁰ = 1

y = 2

Thus, the y-intercept is (0, 2)

Let us check another point

now substitute x = 1

y = 2(5)ˣ

y = 2(5)¹

y = 10

Thus, the value of y = 10 at x = 1

So, we have to two points:

Now, if we carefully observe, we can easily figure out that the graph F represents the function f(x) = 2(5)ˣ.

Because the graph F has a y-intercept (0, 2) and also the point (1, 10) is validating the graph.

Therefore, graph F best represents the function.

The correct graph F is also attached below.

Answer:

I'm pretty sure the answer is c) the graph crosses the y-axis at (0, 4).

Answer:

a) The equation of the Parallel line to the given straight line is

       6 x + y + 13 =0

b) Slope - intercept form

        y = - 6 x - 13

c) The intercept - form

            [tex]\frac{x}{\frac{-13}{6} } + \frac{y}{-13} = 1[/tex]

x - intercept  =  [tex]\frac{-13}{6}[/tex]

y - intercept = - 13

Step-by-step explanation:

Step(i):-

Given the equation of the straight line

                             y = -6x +1

                  6 x + y - 1 = 0

The equation of the Parallel line to the given straight line is

                6x + y + k=0 and it passes through the point (-3, 5 )

           ⇒ 6 (-3 ) + 5 + k =0

          ⇒  - 18 + 5 + k=0

         ⇒   -13 + k = 0

        ⇒     k = 13

The equation of the Parallel line to the given straight line is

       6 x + y + 13 =0

Step(ii):-

Slope - intercept form

                y = m x + C

                y = - 6 x - 13

Step(iii):-

Intercept - form

              6 x + y + 13 =0

              6 x + y = - 13

              [tex]\frac{6x + y}{-13} = \frac{-13}{-13}[/tex]

             [tex]\frac{6x}{-13} + \frac{y}{-13} = 1[/tex]

             [tex]\frac{x}{\frac{-13}{6} } + \frac{y}{-13} = 1[/tex]

The intercept - form

            [tex]\frac{x}{\frac{-13}{6} } + \frac{y}{-13} = 1[/tex]

x - intercept  =  [tex]\frac{-13}{6}[/tex]

y - intercept = - 13
