Write an explicit formula that represents the sequence defined by the following recursive formula
HELP IM TIMED
Answer:
The explicit formula is a[tex]_{n}[/tex] = 5 - 6n
Step-by-step explanation:
The explicit formula of the arithmetic sequence of the recursive formula
a[tex]_{1}[/tex] = first term; a[tex]_{n}[/tex] = a[tex]_{n-1}[/tex] + d is a[tex]_{n}[/tex] = a + (n - 1)d, where
a is the first termd is the common difference between each two consecutive termsn is the position of the number∵ The recursive formula is a[tex]_{1}[/tex] = -1 and a[tex]_{n}[/tex] = a[tex]_{n-1}[/tex] - 6
→ Compare it with the formula above
∴ a = -1 ⇒ 1st term
∴ d = -6 ⇒ common difference
→ Substitute them in the form of the explicit formula
∵ a[tex]_{n}[/tex] = -1 + (n - 1)(-6)
∴ a[tex]_{n}[/tex] = -1 + (-6)(n) - (-6)(1)
∴ a[tex]_{n}[/tex] = -1 + -6n - (-6)
∴ a[tex]_{n}[/tex] = -1 - 6n + 6
→ Add the like term
∴ a[tex]_{n}[/tex] = 5 - 6n
∴ The explicit formula is a[tex]_{n}[/tex] = 5 - 6n

Write an equation in slope-intercept form for the line that passes through the given point and is parallel to the graph of the given equation. (4,-3); y=-5x+8
Answer:
Step-by-step explanation:
The slope of the line is m = -5
4 is your x1
-3 is your y1
Plug into the equation y - y1 = m(x - x1)
y + 3 = -5(x - 4)
y + 3 = -5x + 20
-3 -3
y = -5x + 17

[tex]cos {}^{4} α+sin {}^{4} α= \frac{1}{4} (3+cos4α)
Prove:
Given:
[tex]\cos^4 \alpha+\sin^4\alpha=\dfrac{1}{4}(3+\cos 4 \alpha)[/tex]
To prove:
The given statement.
Proof:
We have,
[tex]\cos^4 \alpha+\sin^4\alpha=\dfrac{1}{4}(3+\cos 4 \alpha)[/tex]
[tex]LHS=\cos^4 \alpha+\sin^4\alpha[/tex]
[tex]LHS=(\cos^2 \alpha)^2+(\sin^2 \alpha)^2[/tex]
[tex]LHS=(\cos^2 \alpha+\sin^2\alpha)^2-2\sin ^2\alpha\cos^2 \alpha[/tex] [tex][\because a^2+b^2=(a+b)^2-2ab][/tex]
[tex]LHS=(1)^2-2(1-\cos^2 \alpha)\cos^2 \alpha [/tex] [tex][\because \cos^2 \alpha+\sin^2\alpha=1][/tex]
[tex]LHS=1-2\cos^2 \alpha+2\cos^4 \alpha [/tex]
Now,
[tex]RHS=\dfrac{1}{4}(3+\cos 4 \alpha)[/tex]
[tex]RHS=\dfrac{1}{4}[3+(2\cos^2 2\alpha-1)][/tex] [tex][\because \cos 2\theta=2\cos^2\theta -1][/tex]
[tex]RHS=\dfrac{1}{4}[2+2\cos^2 2\alpha][/tex]
[tex]RHS=\dfrac{1}{4}[2+2(2\cos^2 \alpha-1)^2][/tex] [tex][\because \cos 2\theta=2\cos^2\theta -1][/tex]
[tex]RHS=\dfrac{1}{4}[2+2(4\cos^4 \alpha-4\cos \alpha+1)][/tex] [tex][\because (a-b)^2=a^2-2ab+b^2][/tex]
[tex]RHS=\dfrac{1}{4}[2+8\cos^4 \alpha-8\cos \alpha+2][/tex]
[tex]RHS=\dfrac{1}{4}[4+8\cos^4 \alpha-8\cos \alpha][/tex]
[tex]RHS=1+2\cos^4 \alpha-2\cos \alpha[/tex]
[tex]RHS=1-2\cos^2 \alpha+2\cos^4 \alpha [/tex]
[tex]LHS=RHS[/tex]
Hence proved.

3 - 2w + 4w = 7?
Answer:
=2
Step-by-step explanation:
Answer:
w= 2
Step-by-step explanation:
3-2w+4w=7. We move all terms to the left: 3-2w+4w-(7)=0, Then we add all the numbers together, and all the variables: 2w-4=0. After, we move all terms containing w to the left, all other terms to the right: 2w=4, w=4/2

Answer:
The correct Option is Option A
Account B because the principal of Account B is $300 and the principal for Account A is $150
Step-by-step explanation:
Interest earned from Account A = $ 4.50
Interest earned from Account B = $22.50
Time t = 18 months
Interest rate for Account A = 2%
Interest rate for Account B = 5%
We need to find which account has greater principal
The formula used to calculate principal is: [tex]Interest=Principal\times r \times t[/tex]
where r is rate and t is time
Finding Principal for Account A:
Interest earned from Account A = $ 4.50
Time t = 18 months = 1.5 years
Interest rate for Account A = 2% = 0.02
Putting values and finding Principal
[tex]Interest=Principal\times r \times t\\4.50=Principal\times0.02\times1.5\\Principal=\frac{4.50}{0.02\times1.5} \\Principal=\frac{4.50}{0.03} \\Principal=150[/tex]
So, The Principal Amount for Account A = $150
Finding Principal for Account B:
Interest earned from Account B = $ 22.50
Time t = 18 months = 1.5 years
Interest rate for Account A = 5% = 0.05
Putting values and finding Principal
[tex]Interest=Principal\times r \times t\\22.50=Principal\times0.05\times1.5\\Principal=\frac{22.50}{0.05\times1.5} \\Principal=\frac{22.50}{0.075} \\Principal=300[/tex]
So, The Principal Amount for Account B = $300
So, the correct Option is Option A
Account B because the principal of Account B is $300 and the principal for Account A is $150

What is a quadratic equation?An algebraic equation of the second degree in x is a quadratic equation. The quadratic equation is written as ax2 + bx + c = 0, where x is the variable, and a must not be zero.
For example 3x² + 6x + 8 = 0 here x has highest term as 3 and coefficient of x² is not zero
Given,
⇒ -4x² - 2x - 5( 1 + x )
⇒ -4x² - 2x - 5 - 5x
