How do you recognize an Arithmetic Sequence? Can you find terms within an arithmetic sequence using a formula
Answer:
An arithmetic sequence is an ordered set of numbers where the difference between each consecutive term is the same (this is called the "common difference").
The formula for each term in an arithmetic sequence is:
[tex]\sf a_n=a+(n-1)d[/tex]
where:
a is the first term in the sequenced is the common difference between consecutive termsn is the position of the term in the sequenceExample
Sequence: 3, 10, 17, 24, 31, ...
The first term in the sequence is 3, therefore a = 3
The common difference can be found by subtracting one term from the next: d = 10 - 3 = 7
Substituting these values into the equation for the nth term:
[tex]\implies \sf a_n=3+(n-1)7[/tex]
[tex]\implies \sf a_n=3+7n -7[/tex]
[tex]\implies \sf a_n=7n -4[/tex]
Therefore, if we want to find the 5th term of the sequence, simply input
n = 5 into the found equation:
[tex]\implies \sf a_5=7(5)-4=31[/tex]
Yes we can find terms
The formula is
a_n=a+(n-1)dWhere
a=first terma_n=nth termd=common differenceA quadratic equation of the form 0=ax2 bx c has a discriminant value of -16. how many real number solutions does the equation have? -1 0 1 2
The provided quadratic equation, which has a negative discriminant value of -16, has no real number solutions.
What is the discriminant value in a quadratic equation?The standard form of the quadratic equation is,
[tex]ax^2+bx+c=0[/tex]
Here,(a,b, c) is the real numbers and (x) is the variable.
For this equation, the discriminant value can be given as,
[tex]D=b^2-4ac[/tex]
In this equation,
If the discriminant value is positive (D>0), then the equation has 2 real solution.If the discriminant value is equal to zero (D=0), then the equation has 1 real solution.When the discriminant value is negative (D<0), then the equation has 2 imaginary solution.The quadratic equation given as,
[tex]0=ax^2 +bx +c[/tex]
This quadratic equation has a discriminant value of -16. As the value of discriminant is negative, thus it has no real solution.
Hence, the provided quadratic equation, which has a negative discriminant value of -16, has no real number solutions.

A small cube has a volume of 64 cubic feet. A larger cube has sides that are three times as long as the small cube. How long are the sides of each cube?
The side of a larger cube is equal to 12 ft meanwhile the side of a small cube is equal to 4 ft.
Volume of a CubeA cube is a 3D- form of a square and its volume is found in the formula:
V=s³, where: s is the length of each side of a cube.
If the small cube has a volume ([tex]V_s[/tex]) of 64 ft³, you can apply the formula V=s³ for finding its the length of its sides. Thus
[tex]V_s[/tex]=64 ft³
[tex]s_v^3[/tex]=64
[tex]s_v=\sqrt[3]{64}\\ \\ s_v=4 ft[/tex]
A larger cube has sides ([tex]s_l[/tex]) that are three times as long as the small cube. Therefore, [tex]s_l=3s_v[/tex]. If [tex]s_v[/tex]=4 ft, the [tex]s_l[/tex] will be:
[tex]s_l=3s_v\\ \\ s_l=3*4\\ \\ s_l=12 ft[/tex]

Please help! I know me have 10 minutes! Find all solutions to 20cos(2pi/5 x) = 10✔️2
Answer: A
Step-by-step explanation:
You have:
[tex]20cos(\frac{2\pi }{5} x)=10\sqrt{2}[/tex]
Begin by dividing both sides by 20 to get:
[tex]cos(\frac{2\pi }{5} x)=\frac{\sqrt{2} }{2}[/tex]
Take the arccosine of both sides to get:
[tex]arccos(cos(\frac{2\pi }{5} x))=arccos(\frac{\sqrt{2} }{2})[/tex]
[tex]\frac{2\pi }{5} x=arccos(\frac{\sqrt{2} }{2} )[/tex]
First of all, lets find the right side. Cosine of what gives sqrt 2 over 2? That would be pi/4, plus 2npi. Another solution would be 7pi/4, plus 2npi. We have:
[tex]\frac{2\pi }{5} x=\pi /4+2n\pi[/tex]
[tex]\frac{2\pi }{5} x=7\pi /4+2n\pi[/tex]
Isolate 'x' to get:
[tex]x=\frac{5}{2\pi } (\pi /4+2n\pi)=\frac{5}{8} +5n[/tex]
[tex]x=\frac{5}{2\pi } (7\pi /4+2n\pi)=\frac{35}{8} +5n[/tex]

Answer:
∠1 = 130°
∠2 = 50°
∠3 = 130°
Step-by-step explanation:
As we can see Angles 1 and 50° are on a straight line. As :
Angles on a straight line add up to 180. So :
50 + ∠1 = 180
∠1 = 180-50
∠1 = 130
As we can angles 1 and 2 are on a straight line. As :
Angles on a straight line add up to 180. So :
∠1 + ∠2 = 180
As we worked out ∠1 we can substitute that in to work out ∠2 :
130 + ∠2 = 180
∠2 = 180-130
∠2 = 50
As we can angles 2 and 3 are on a straight line. As :
Angles on a straight line add up to 180. So :
∠2 + ∠3 = 180
As we worked out ∠2 we can substitute that in to work out ∠3 :
50 + ∠3 = 180
∠3 = 180-50
∠3 = 130

The area of a triangle is found by multiplying half of the measure of its base by its height. The area of the following right triangle is 18 square centimeters.
A. Write and solve an equation to find the value of h. Include all of your work in your answer.
B. In two or more complete sentences, verify your answer using mental math.
50 points
Answer:
[tex]\sf Area\:of\:a\:triangle=\dfrac12 \times base \times height[/tex]
Given:
area = 18 cm²base = 6 cmheight = (h + 1) cmSubstitute the given values into the equation and solve for h:
[tex]\sf \implies 18 = \sf \dfrac12 \times 6 \times (h+1)[/tex]
[tex]\sf \implies 18 = \sf \dfrac62 (h+1)[/tex]
[tex]\sf \implies 18 =3(h+1)[/tex]
expand using distributive property of addition [tex]a(b+c)=ab+ac[/tex]:
[tex]\sf \implies 18=3h+3[/tex]
subtract 3 from both sides:
[tex]\sf \implies 3h=15[/tex]
divide both sides by 3:
[tex]\sf \implies h=5[/tex]
To verify:
Half of the base is 3 cm.
If h=5, then the height of the triangle is 6 cm.
Multiplying 3 by 6 is 18.
This matches the given area, so we can verify that h = 5.
Answer:
Below!
Step-by-step explanation (a):Given:
Area of Triangle = 18 cm²Base of Triangle = 6 cmHeight of (Triangle = (h + 1) cmFormula:
[tex]\text{Area of triangle} = \dfrac{1}{2} \times \text{Base} \times \text{Height}[/tex]
Substitute the measures into the formula:
[tex]:\implies 18 \ \text{cm}^{2} = \dfrac{1}{2} \times 6 \times \text{(h} + 1\text{)}[/tex]
SImplify the R.H.S:
[tex]:\implies18 \ \text{cm}^{2} = 3 \times \text{(h} + 1\text{)}[/tex]
Divide both sides by 3:
[tex]:\implies \dfrac{18}{3} = \dfrac{3 \times \text{(h} + 1\text{)}}{3}[/tex]
Simplify both sides:
[tex]:\implies 6 = \text{(h} + 1\text{)}[/tex]
Subtract 1 both sides:
[tex]:\implies 6 - 1 = \text{h} + 1- 1[/tex]
Simplify both sides:
[tex]:\implies 5= \text{h}[/tex]
Step-by-step explanation (b):Reviewing on how to verify our answer:
We can verify our answer by substituting the value of "h" in (h + 1) to determine the height of the triangle. Then we can substitute the height and the base in the "area of triangle" formula (1/2 x Base x Height).
Note: Keep in mind that the evaluated area should be 18 cm², as said in the question. If the area evaluated is different from 18 cm², then the value of "h" is incorrect.Verifying our answer through mental math:
Clearly, the height of the triangle is 6 cm, as when "h" is substituted in the expression (h + 1), we get 5 + 1.As said above, the formula for determining the area of a triangle is 1/2 x Base x Height. Clearly, half of 6 is 3. Lastly, when 6 (Base) and 3 (Half of the height) are multiplied, we get 18 cm², which is the area stated in the question.Thus, the value of "h" is verified through mental math.

What is a rectangle?It is a polygon that has four sides. The sum of the internal angle is 360 degrees. In a rectangle, opposite sides are parallel and equal and each angle is 90 degrees. And its diagonals are also equal and intersect at the mid-point.
The length of the rectangle will be (x₂ - x₁) and the width of the rectangle will be (y₂ - y₁).
Then the perimeter of the rectangle will be
Perimeter = 2(x₂ - x₁) + 2(y₂ - y₁)
