Answer:

12, 17, 24

Step-by-step explanation:

To find the first 3 terms, substitute n = 1, 2, 3 into the rule, that is

T₁ = 1² + 2(1) + 9 = 1 + 2 + 9 = 12

T₂ = 2² + 2(2) + 9 = 4 + 4 + 9 = 17

T₃ = 3² + 2(3) + 9 = 9 + 6 + 9 = 24

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

From the picture.

We have to see the line from A, B, C, and D that touches the numbers given.

Now,

A touches the number 4

B touches the number 3

C touches the number 2

D touches the number 1

The 4-digit number must be written in the sequence of ABCD.

So,

4321 is our four-digit number.

Thus,

The correct 4-digit code is 4321.

hope that helps!

Answer:

d=2/5 or d=2

Step-by-step explanation:

Step 1: Subtract -6d^2 from both sides.

−d2−12d+4−−6d2=−6d2−−6d2

5d2−12d+4=0

Step 2: Factor left side of equation.

(5d−2)(d−2)=0

Step 3: Set factors equal to 0.

5d−2=0 or d−2=0

d= 2/5 or d=2

Answer:

TriangleJXP = Triangle HCD

Side XJ = side HC

Side CD = side JP

Side PX = HD

Step-by-step explanation:

Looking at both of the triangles you use the lines on “top” of the side. These lines represent congruence meaning that they are similar to each other.

So looking at side JP u can see that there are two lines meaning that this is the second side that is congruent to another side, side CD.

Hope this helps.

Step-by-step explanation:

Answer:

a. 121

b. 32100

c. 0.2

d. 400

Step-by-step explanation:

a. Quick disclaimer: If there's a decimal point on the divisor, in this case it would be .05, you have to move the decimal point until it has no decimal, in this case .05 would become 5.0 or just 5. The other number also has to have it's decimal point moved as much as the divisor, in this case two times, so it would be from 6.05 to 605. So with this in mind: 605/5 = 121

b. 96.3/.003 = 96300/3 = 32100

c. 0.12/0.6 = 1.2/6 = 0.2

d. 3.2/.008 = 3200/8 = 400

In mathematics, the logarithm is the inverse function to exponentiation. That means the logarithm of a given number x is the exponent to which another fixed number, the base b, must be raised, to produce that number x.

Answer: Choice (3) which is the sequence –2, –7, –12, ...

Here we start with -2 and subtract off 5 each time we need a new term

-2-5 = -7

-7-5 = -12

and so on.

The notation f(n+1) = f(n) - 5 tells us "subtract 5 from the nth term, called f(n), to get the next term f(n+1)"

Answer:

A missing angle in a right angle.

Step-by-step explanation:

Given, the inverse of trigonometric functions sine, cosine and tangent.

To find:

The value that can be found using the inverse trigonometric functions.

Solution:

First of all, let us consider the right angled triangle attached in answer area.

Hypotenuse is AC, Base is BC and AB is the Altitude/Height of the right angled [tex]\triangle ABC[/tex].

Let us suppose all three sides are known and [tex]\angle C[/tex] is unknown.

Formula:

[tex]1.\ sin\theta = \dfrac{Perpendicular}{Hypotenuse}[/tex]

[tex]2.\ cos\theta = \dfrac{Base}{Hypotenuse}[/tex]

[tex]3.\ tan\theta = \dfrac{Perpendicular}{Base}[/tex]

Let us consider [tex]\angle C[/tex].

[tex]sin C = \dfrac{AB}{BC}[/tex]

If we taken inverse:

[tex]sin^{-1} sinC = sin^{-1} (\frac{AB}{BC})[/tex]

[tex]\Rightarrow \angle C = sin^1\frac{AB}{BC}[/tex]

Similar is the case for cosine and tangent.

Therefore, the missing angle of the right angled triangle can be calculated by the inverse of sine, cosine and tangent.

Answer:

[tex]y=-\frac{1}{4}x+4[/tex]

Step-by-step explanation:

So we pick one point from the graph

(0, 4)

[tex]y-y_{1}=m(x-x_{1} ) \\y-4=-\frac{1}{4}(x-0)[/tex]

Answer:

[tex]y-4=-\frac{1}{4}(x)[/tex]

Step-by-step explanation:

Point slope form = y − y1 = m(x − x1)

Our point is 0,4.

So the point slope is

[tex]y-4= (slope)(x)[/tex]

The slope is -1/4.

so,

[tex]y-4=-\frac{1}{4}(x)[/tex]

This is the answer.

Answer: A. 1/9

Step-by-step explanation:

to find what fraction of all your books is historical fiction, you would multiply how the fraction of all your books that are fiction by the fraction of fictional books that are historical fiction.

this gives you 2/3 times 1/6.

from there you simply multiply the numerators (2x1=2)

and the denominators (3x6=18)

leaving you with 2/18

but that can be simplified, giving you the final answer of 1/9

Answer:

We conclude that the sequence is NEITHER geometrc nor arithmetic.

Step-by-step explanation:

Given the sequence

[tex]2,6,10,16,...[/tex]

As we know that

An arithmetic sequence has a constant difference d and is defined by:

[tex]a_n=a_1+\left(n-1\right)d[/tex]

Computing the differences between all adjacent terms:

[tex]6-2=4,\:\quad \:10-6=4,\:\quad \:16-10=6[/tex]

The difference is not constant

Hence, the sequence is NOT arithmetic.

NOW, let's check whether is a geometric sequence or not

A geometric sequece has a constant common ration r and is defined by:

[tex]a_n=a_0\cdot r^{n-1}[/tex]

Computing the common ratios between all adjacent terms:

[tex]\frac{6}{2}=3,\:\quad \frac{10}{6}=1.66666\dots ,\:\quad \frac{16}{10}=1.6[/tex]

The ratio is not constant

Hence, the sequence is NOT geometric.

Therefore, we conclude that the sequence is NEITHER geometrc nor arithmetic.

Answer:

All options

Step-by-step explanation:

In each option, the left and right side of the equation are identical, meaning whatever values that [tex]x[/tex] take will result in the left and right side of the equation to be equal. This means that the equation will have infinitely many solutions.
