pls help how do i solve log(5x+2)=1

like what rule do I use and how do I do it step by step

Answer:

Step-by-step explanation:

If you have $2250 as against an inflation rate of 2% every year, this then means that after the first year, the value of your money becomes

2250 * 2% =

2250 * 0.02 = 45

2250 - 45 = $2205

At the end second year

$2205 * 2% =

$2205 * 0.02 = 44.1

$2205 - 44.1 = 2160.9

At end of the third year

$2160.9 - 2% =

$2160.9 * 0.02 = 43.218

$2117.682

And so on, and so forth

There are 20 red tickets Jeanette drew on each attempt.

The process of combining two or more numbers is called the Addition. The 4 main properties of addition are commutative, associative, distributive, and additive identity.

Given that;

There are 50 tickets in a jar.

And, Each ticket is either red or blue.

Here, Jeanette randomly draws 10 tickets from the jar, counts the number of red tickets, and then replaces the tickets.

She does this 8 times.

Hence, We get;

Mean = 3 + 4 + 6 + 7 + 3 + 4 + 2 + 3 / 8

         = 32 / 8

         = 4

The ratio of the red tickets = 4 / 10 = 2 / 5

Now, Let number of red tickets = x

Hence,

⇒ x / 50 = 2 / 5

⇒ x = 20

Thus, There are 20 red tickets Jeanette drew on each attempt.

Width=w

Can be written as 3w+w+3w+w

Combine like terms to get 8w

120/8=15

w=15

Width=15 inches

Length=3(15)=45

Length=45 inches

False. Type II error and power are complementary probabilities. The power of a statistical test is the probability of rejecting the null hypothesis when it is false (i.e., correctly detecting a significant effect or difference).

On the other hand, the type II error is the probability of failing to reject the null hypothesis when it is false (i.e., failing to detect a significant effect or difference).

Therefore, if the probability of committing a type II error is 0.20, then the power of the test is 1 - 0.20 = 0.80. This means that there is an 80% chance of correctly detecting a significant effect or difference.

However, we cannot determine the power of a statistical test from the probability of committing a type II error alone. We would need additional information such as the sample size, effect size, alpha level, and variability to calculate the power of the test.

If f(5) = 11, f ′ is cοntinuοus, and 6 5 f ′(x) dx = 19, then f(6) = 30.

Tο find the value οf f(6), we can use the Fundamental Theοrem οf Calculus. Accοrding tο the theοrem, if f(x) is cοntinuοus οn an interval [a, b] and F(x) is an antiderivative οf f(x) οn that interval, then the definite integral οf f(x) frοm a tο b is equal tο F(b) - F(a).

Given that f'(x) is cοntinuοus, we can apply the theοrem tο the integral:

∫₅₆ f'(x) dx = f(6) - f(5)

We are given that ∫₅₆ f'(x) dx = 19, and f(5) = 11. Plugging in these values, we have:

19 = f(6) - 11

Tο sοlve fοr f(6), we add 11 tο bοth sides:

f(6) = 19 + 11

f(6) = 30

Therefοre, the value οf f(6) is 30.

By using the basic comparison test and limit comparison test for the series: 3Σn=1 to ∞ a₁n³e⁻ⁿ², The number π²/2 is a finite number, and the series 3Σn=1 to ∞ a₁n³e⁻ⁿ² is convergent.

Part 1: We need to identify whether the given series is converging or diverging.

Part II: We can use the basic comparison test to test the convergence of the given series. Let's compare the given series with another series that is easily recognizable and convergent. For

n ≥ 1, a₁n³e⁻ⁿ² > 0

We know that the series Σ a₁n³e⁻ⁿ² is convergent, which means that the sequence of terms must be converging to zero as well. This can be shown using the following limit statement.

lim n→∞ a₁n³e⁻ⁿ² = 0.

By comparing the series with a simpler convergent series, we can prove that the series is convergent. The simpler convergent series can be represented by the expression 3Σn=1 to ∞ 1/n². This series is known as the p-series with p = 2. We can use this series to perform a comparison test.

Let Sn be the nth partial sum of the given series. Thus,

3Σn=1 to ∞ a₁n³e⁻ⁿ² ≤ 3Σn=1 to ∞ 1/n²

Let's evaluate the second series using the formula for the sum of a p-series:

Σn=1 to ∞ 1/n² = π²/6

Thus, 3Σn=1 to ∞ a₁n³e⁻ⁿ² ≤ 3 x π²/6

The value of x at which the slope of the tangent line to the given function is equal to 5 is 4. Thus, the correct answer is option (b).

The incline of the digression line to the capability y=x²-3x+2 at some random point (x₀, y₀) on the bend is given by the subordinate of the capability by then. To find the worth of x for which the slant of the digression line is equivalent to 5, we want to separate the given capability and set it equivalent to 5 and afterward tackle for x.

Therefore, let's distinguish the function from x: dy/dx = 2x - 3 Now, we need to set this derivative to 5: 2x - 3 = 5. If we solve for x, we get: 2x = 8x = 4. This means that the value of x at which the tangent line to the given function is equal to 5 is 4. Accordingly, the right response is choice (b).

The given differential equation is not exact. To determine if a differential equation is exact, we need to check if its partial derivatives satisfy a specific condition.

In this case, the given equation is dy/dx = 9xe^x – y + 6x^2. Let's find the partial derivatives of the expression on the right-hand side with respect to y and x.∂/∂y (9xe^x – y + 6x^2) = -1∂/∂x (9xe^x – y + 6x^2) = 9e^x + 12x

The condition for exactness is that these partial derivatives are equal: ∂/∂y (∂/∂x) = ∂/∂x (∂/∂y). However, in this case, we have -1 ≠ 9e^x + 12x, which means the equation is not exact.As the equation is not exact, we cannot directly solve it by finding a potential function. Other methods, such as using integrating factors or applying specific techniques for solving non-exact equations, may be required.

The solution of the given differential equation using the Laplace transform is y(t) =  1 −  [tex]e^{2t}[/tex] + 2 [tex]e^{-t}[/tex].

Given differential equation is y″−2y = eˣ, y(0) = 0, y′(0) = 0. We will solve it using Laplace transforms.

To solve the given differential equation using the Laplace transform, take the Laplace transform of each term of the differential equation. Then solve for Y(s) and find y(t) by taking the inverse Laplace transform.

Here, we take L{y} for Y(s) and L{y''} and L{y'} for s²Y(s) and sY(s) respectively.

L[y′′] − 2L[y] = L[eˣ] s²Y(s) − s⋅y(0) − y′(0) − 2Y(s)

= 1s − 1.0 − 0 − 2Y(s)

= 1s − 1 

We have to rearrange the terms of the above equation in order to get Y(s) on one side.

Y(s) = 1s(s−2)(s−1) = As+Bs−2+Cs−1.

Using partial fraction expansion, A=1, B=1, and C=−2.

So,Y(s) = 1s+(1s−2)−2s−1.

We can write Y(s) as follows.Y(s) = 1s−(1s−2)+2s−1.

Then find the inverse Laplace transform of Y(s) to get the solution y(t).

y(t) = L − 1{Y(s)} = L − 1{1s} − L − 1{1s−2} + L − 1{2s−1}

= 1 −  [tex]e^{2t}[/tex] + 2 [tex]e^{-t}[/tex].

Therefore, the solution of the given differential equation using Laplace transform is y(t) =  1 −  [tex]e^{2t}[/tex] + 2 [tex]e^{-t}[/tex].

The given identities can be verified using basic rules of exponentials and algebra. Here are the steps to verify the given identities:

(a) 1 = ∑_(n=1) ^∞▒〖10^(x)+2(-1) ^nln⁡(x)〗0

Rewrite the sum to obtain two series, one for even values of n, and one for odd values of n. ∑_(n=1)^∞▒10^(x) = 10^x+10^x+...= (2/3) (10^x) (odd terms only)∑_(n=1)^∞▒〖(-1)^nln⁡(x)〗= ln(x)-ln(x)+ln(x)-ln(x)+...= (0) (even terms only)

Thus, we have 1= (2/3) (10^x) + (0) = (2/3) (10^x) (b) e^x = ∑_(n=1) ^∞▒〖10^x+2n(x)〗

Rewrite the sum to obtain two series, one for even values of n, and one for odd values of n.

∑_(n=1) ^∞▒10^(x) = 10^x+10^x+...= (1/2) (10^x) (even terms only) ∑_(n=1) ^∞▒〖2n(x)〗= 2(x)+2(2x) +2(3x) +...= 2x (1+2+3+...) = -x/(-1) ^2= -x

Thus, we have e^x= (1/2) (10^x) - x(c) e^(-x) = ∑_(n=1) ^∞▒〖10^x+2(-1) ^nln⁡(x)〗0

We can use the same series from part (a) with x replaced by -x.

Thus, we have e^(-x) = (2/3) (10^(-x)) + (0) = (2/3) (1/10^x)

Similarly, e^x= (2/3) (10^x) Subtracting these two equations, we get: e^x - e^(-x) = (2/3) (10^x + 1/10^x) (answer) (d)

Cosh x = ∑_(n=0) ^∞▒〖10^x+2n(x)〗

Similar to part (b), we have two series, one for even values of n, and one for odd values of n.∑_(n=0)^∞▒10^(x) = 1+10^x+10^x+...= (1/2) (10^x) (even terms only)∑_(n=0)^∞▒〖2n(x)〗= 0+2x+2(2x)+2(3x)+...= 2x (1+2+3+...)= 2x(1/(-1)^2)= 2xThus, we have Cosh(x) = 1 + (1/2) (10^x) + 2x (e^x)(e^x - e^(-x)) / 2= 1 + (1/2) (10^x) + 2x (1 + (2/3) (10^x + 1/10^x)) (answer)(e) Sinh x = ∑_(n=1)^∞▒〖2^(2n-1)(x)〗

Rewrite the sum to obtain two series, one for even values of n, and one for odd values of n.∑_(n=1)^∞▒〖2^(2n-1)(x)〗= 2x+2^3x+2^5x+...= 2x(1+2^2+2^4+...)= 2x(2^0+2^2+2^4+...)= 2x(1/ (1-2^2))= -2x/3Thus, we have Sinh(x) = ∑_(n=1)^∞▒〖2^(2n-1)(x)〗= 2x/3 (answer)
