Rewrite the function in the form y=a(1+r)^t calculator
When the function, y = a(6) ^ (t/2) is rewritten in the needed form, it would be y = a(1 + 1.449) ^ t.
How can the function be rewritten?When 6 is taken to the power of (t / 2), this can be shown as:
= √6 ^ t
The square root of 6 is:
= √6
= 2.449
Formula therefore becomes:
= a (2.449) ^ t
Subtract 1 from the brackets to become:
y = a (1 + 1.449) ^ t

Evaluate the indefinite integral as an infinite series. arctan(x2) dx
The indefinite integral expressed as an infinite series is;
[tex]= (\Sigma^{\infty} _{n = 0} (-1)^{n} \frac{1 }{2n + 1} * \frac{(x)^{4n + 3}}{4n + 3}) + C[/tex]
How to find indefinite integral?We will first have to look for the Maclaurin series of arctan(x).
We'll recall that from online tables of integral, this Maclaurin series of arctan(x) will have the general formula;
[tex]arctan(x) = \Sigma^{\infty} _{n = 0} (-1)^{n} \frac{x^{2n + 1} }{2n + 1}[/tex]
When we apply that general Maclaurin series of arctan(x) to our question of arctan(x²), we have the expression as;
[tex]arctan(x^{2} ) = \Sigma^{\infty} _{n = 0} (-1)^{n} \frac{(x^2)^{2n + 1} }{2n + 1}[/tex]
⇒ [tex]= \Sigma^{\infty} _{n = 0} (-1)^{n} \frac{(x)^{4n + 2} }{2n + 1}[/tex]
We now integrate the expression that we got above in the following manner to get;
[tex]\int\limitsarctan(x^{2} ) = \int\Sigma^{\infty} _{n = 0} (-1)^{n} \frac{(x)^{4n + 2} }{2n + 1} dx[/tex]
⇒ [tex]= (\Sigma^{\infty} _{n = 0} (-1)^{n} \frac{1 }{2n + 1} * \frac{(x)^{4n + 3}}{4n + 3}) + C[/tex]
Thus, that expression gives us the indefinite integral of arctan(x²) as an infinite series.

Suppose that we have this spinner. what is the probability of landing on 4 after landing on 4?
The probability that the spinner lands on 4 is its likelihood
The probability of landing on 4 after landing on 4 is 1/n^m
How to determine the probability?Assume that the numbers on the spinner are not repeated, the probability that a spinner lands on 4 is:
P(4) = 1/n
Where n represents the number of sections on the spinner
The probability that the spinner lands on 4 again is the same for the number of times the spinner is spun
Hence, the probability of landing on 4 after landing on 4 is 1/n^m where m represents the number of spins

Determine whether f is an exponential function of x. if so, find the constant ratio
The constant ratio of the function f is its growth rate
The function f is an exponential function with a constant ratio of 2
How to determine if the function is an exponential function?To do this, we simply divide the consecutive function values
From the complete question (see attachment for the table), we have:
f(-1) = 1/4
f(0) = 1/2
f(1) = 1
f(2) = 2
Divide the function values to get the ratio, r
r = f(2)/f(1) = f(1)/f(0) = f(0)/f(-1)
This gives
r = 2/1 = 1 / 1/2 = 1/2 / 1/4
Evaluate the quotients
r = 2 = 2 = 2
The value of r is the same for the three quotients.
Hence, the function f is an exponential function with a constant ratio of 2

We add them to be 4x + 5x + 9x =180°
18x=180° =
x= 180/18
x = 18
So therefore the angles are:

Given 30.00 ml of 0.10 m acetic acid and 50.00 ml of 0.100 m koh, the pH of the solution is 12.40
What is the pH of a substance?This is the measure of the acidity or the basicity of an aqueous or liquidsolution.
The details that are contained in this question are:
Mole of CH3COOH = 0.1 M
Volume of CH3COOH = 30 mL
Mole of KOH = 0.1 M
Volume of KOH = 50 mL
mol of (CH3COOH) = 0.1 Mole * 30 mL = 3 mol
mol of (KOH) = 0.1 Mole * 50 mL = 5 mol
From the solution above,
mol of CH3COOH = 3 mol
mol of KOH = 5 mol
3 mol of both substances is going to react
excess KOH remaining = 5 - 3 = 2 mmol
Volume of both Solutions
= 30 + 50 = 80 mL
OH⁻ = 2/80
= 0.025 M
use:
pOH = -log [OH-]
= -log (0.025)
pOH = 1.602
