After 11 years,188.76 more money would Lincoln have in his account than Robert

percentage, a relative value indicating hundredth parts of any quantity.

Given,

Lincoln invested $440 in an account paying an interest rate of 7 ​% compounded continuously.

Robert invested $440 in an account paying an interest rate of 5 ​ %.

We need to find how much more money would Lincoln have in his account than Robert in 11 years.

\(A=Pe^{rt}\)

For Lincoln:

P=440,

r=7%=0.07

t=11

A=440e⁰⁰⁷ˣ¹¹

A=440e⁰⁷⁷

A=949.96

For  Robert,

P=440,

r=5%=0.05

A=440e⁰⁰⁵ˣ¹¹

A=440e⁰⁵⁵

A=761.2

Now find the difference of Albert and Robert money

949.96-761.2

188.76

Hence, After 11 years,188.76 more money would Lincoln have in his account than Robert

43.36% of the scores fall between 690 and 900 on the collegiate mathematics readiness assessment.

To determine the percentage of scores between 690 and 900, we need to calculate the area under the normal distribution curve between these two values.

First, we need to standardize the scores using the formula z = (x - μ) / σ, where x is the score, μ is the mean, and σ is the standard deviation.

For the score 690:

z1 = (690 - 680) / 120 = 0.0833

For the score 900:

z2 = (900 - 680) / 120 = 1.8333

Next, we need to find the area between these two standardized scores. We can use a standard normal distribution table or a statistical calculator to find the corresponding probabilities.

From the standard normal distribution table, we find that the area to the left of z1 is approximately 0.5328 and the area to the left of z2 is approximately 0.9664.

To find the area between z1 and z2, we subtract the smaller area from the larger area:

Area = 0.9664 - 0.5328 = 0.4336

Finally, we convert the area to a percentage by multiplying by 100:

Percentage = 0.4336 * 100 ≈ 43.36%

Therefore, approximately 43% of the scores fall between 690 and 900 on the collegiate mathematics readiness assessment.

Answer:

D

Step-by-step explanation:

for a table to represent a function each x value can only have one y value here we see 5 have two different values, 3 and 2, so it is not a function

Answer:

a = 3.14

b = 6.28

Step-by-step explanation:

The interval where the function is decreasing is where increasing x values result in decreasing y values. The y values peak at the point (3.14, 2) and decrease until the point (6.28, 0) where the function starts increasing again.

The derivative of the tower function y = (cot(3x))^x^2 is given by:

(dy/dx) = y * (2 * ln(cot(3x)) + 2x * (d/dx) ln(cot(3x)) - 3x^2 * (d/dx) (cot(3x)) * cos(3x) / sin^2(3x))

To find the derivative of the tower function y = (cot(3x))^x^2 using logarithmic differentiation, we follow these steps:

Step 1: Take the natural logarithm of both sides of the equation:

ln(y) = ln((cot(3x))^x^2)

Step 2: Apply the logarithmic properties to simplify the expression:

ln(y) = x^2 * ln(cot(3x))

Step 3: Differentiate both sides of the equation implicitly with respect to x:

(d/dx) ln(y) = (d/dx) (x^2 * ln(cot(3x)))

Step 4: Use the chain rule and product rule on the right side of the equation. Let's calculate each derivative separately:

(d/dx) ln(y) = (d/dx) (x^2 * ln(cot(3x)))

= (d/dx) x^2 * ln(cot(3x)) + x^2 * (d/dx) ln(cot(3x))

The derivative of x^2 with respect to x is 2x. Now, let's calculate the derivative of ln(cot(3x)) using the chain rule.

Let u = cot(3x)

So, ln(cot(3x)) = ln(u)

Apply the chain rule:

(d/dx) ln(u) = (1/u) * (d/dx) u

To find (d/dx) u, we need to differentiate cot(3x) with respect to x. Applying the chain rule again:

(d/dx) u = (d/dx) cot(3x)

= -(1/sin^2(3x)) * (d/dx) (sin(3x))

= -(1/sin^2(3x)) * 3cos(3x)

Now, substitute these results back into the equation:

(d/dx) ln(y) = 2x * ln(cot(3x)) + x^2 * (1/cot(3x)) * -(1/sin^2(3x)) * 3cos(3x)

Step 5: Simplify the expression further:

(d/dx) ln(y) = 2x * ln(cot(3x)) - 3x^2 * cot(3x) * cos(3x) / sin^2(3x)

Step 6: Convert the derivative of ln(y) back to the derivative of y by taking the exponential of both sides:

e^((d/dx) ln(y)) = e^(2x * ln(cot(3x)) - 3x^2 * cot(3x) * cos(3x) / sin^2(3x))

The left side simplifies to y, so we have:

y = e^(2x * ln(cot(3x)) - 3x^2 * cot(3x) * cos(3x) / sin^2(3x))

Thus, the derivative of the tower function y = (cot(3x))^x^2 is given by:

(dy/dx) = y * (2 * ln(cot(3x)) + 2x * (d/dx) ln(cot(3x)) - 3x^2 * (d/dx) (cot(3x)) * cos(3x) / sin^2(3x))

Simplifying the expression further involves substituting the appropriate derivatives of cot(3x) and evaluating trigonometric functions, but this is the general form of the derivative using logarithmic differentiation.

The requried simplified value b in the given expression is 4.

Simplification involves applying rules of arithmetic and algebra to remove unnecessary terms, factors, or operations from an expression.

Here,
We are given the function,

f(x) = a + x + bx

We know that f(3) = 15 + a, so substituting x = 3 in the function, we get,

f(3) = a + (3) + b(3) = 15 + a

Simplifying this equation, we get,

a + 3 + 3b = 15 + a

Subtracting a from both sides, we get,

3 + 3b = 15

Subtracting 3 from both sides,

3b = 12

Answer:

width = 9/2 inches, length = 18 inches

Step-by-step explanation:

Step-by-step explanation:

l = length

w = width

l×w = 81 in²

l = 2w + 9

we can use the identity of the second equation in the first equation :

(2w + 9)×w = 81

2w² + 9w = 81

2w² + 9w - 81 = 0

the general solution to such a quadratic equation is

x = (-b ± sqrt(b² - 4ac))/(2a)

in our case

x = w

a = 2

b = 9

c = -81

w = (-9 ± sqrt(9² - 4×2×-81))/(2×2) =

= (-9 ± sqrt(81 + 648))/4 =

= (-9 ± sqrt(729))/4 = (-9 ± 27)/4

w1 = (-9 + 27)/4 = 18/4 = 9/2 in

w2 = (-9 - 27)/4 = -36/4 = -9

a negative solution for a side length does not make any sense, so, width = 9/2 in is the only valid solution.

l = 2w + 9 = 2×9/2 + 9 = 9+9 = 18 in

so, the last answer option is correct.

There are n x (n-1) number of ways for the speaker and vice speaker to be selected in the demonstrator's party, where n is the number of members in the party.

For the demonstrator's party, the first position of the speaker can be filled by any of the n members. After the speaker is chosen, there are n-1 members left to select from for the position of vice speaker. Therefore, the total number of ways the speaker and vice speaker can be selected is n x (n-1).

For example, if the demonstrator's party has 4 members, there are 4 choices for the speaker position. After the speaker is chosen, there are 3 choices left for the position of vice speaker. So, the total number of ways to select a speaker and vice speaker in the party is 4 x 3 = 12.

The true statement for the function p(x) is p(-2) and p(0) cannot be compared because p(0) is undefined. Option D is correct.

The given function is a logarithmic function and it is undefined at x = 0.

First, let us understand the logarithmic function:

A logarithmic function is a function of the form which is read as “ y equals the log of x, base b” or “ y equals the log, base b, of x.” In both forms, x > 0 and b > 0, b ≠ 1.

We are given:

p(x) = log 5x

substitute x = 0 in the above equation, we will get;

p(0) = log 5 * 0

p(0) = log 0

p(0) = undefined

Using product rule and chain rule, the derivative of the function y = (x² + 2)(x³ + x² + 1)² is given by:

y' = 2x(x³ + x² + 1)² + 2(x² + 2)(x³ + x² + 1)(3x² + 2x)

To find the derivative of the function y = (x² + 2)(x³ + x² + 1)², we can use the product rule and the chain rule.

Let's denote the first factor (x² + 2) as u and the second factor (x³ + x² + 1)² as v.

Using the product rule (u * v)', the derivative of the function is given by:

y' = u' * v + u * v'

First, let's find the derivative of u (x² + 2):

u' = d/dx (x² + 2)

  = 2x

Next, let's find the derivative of v (x³ + x² + 1)² using the chain rule:

v' = d/dx (x³ + x² + 1)²

  = 2(x³ + x² + 1) * (d/dx (x³ + x² + 1))

  = 2(x³ + x² + 1) * (3x² + 2x)

Now we can substitute the values of u, u', v, and v' into the derivative formula:

y' = (2x) * (x³ + x² + 1)² + (x² + 2) * [2(x³ + x² + 1) * (3x² + 2x)]

Simplifying further:

y' = 2x(x³ + x² + 1)² + (x² + 2) * 2(x³ + x² + 1) * (3x² + 2x)

y' = 2x(x³ + x² + 1)² + 2(x² + 2)(x³ + x² + 1)(3x² + 2x)
