The sign of each of the functions in the given interval is positive.

Suppose \( \theta \) is in the interval \( \left(90^{\circ}, 180^{\circ}\right) \), we can find the sign of each of the following functions by using the unit circle and the reference angles.

77. \( \cos \frac{\theta}{2} \)
Since \( \theta \) is in the second quadrant, \( \frac{\theta}{2} \) will be in the first quadrant. Therefore, the sign of \( \cos \frac{\theta}{2} \) will be positive.

78. \( \sin \frac{\theta}{2} \)
Similarly, since \( \theta \) is in the second quadrant, \( \frac{\theta}{2} \) will be in the first quadrant. Therefore, the sign of \( \sin \frac{\theta}{2} \) will be positive.

79. \( \sec \frac{\theta}{2} \)
The secant function is the reciprocal of the cosine function, so the sign of \( \sec \frac{\theta}{2} \) will be the same as the sign of \( \cos \frac{\theta}{2} \), which is positive.

In conclusion, the sign of each of the functions in the given interval is positive.

The Rational Zero Theorem states that if f(x) is a polynomial with integer coefficients, then any rational zero of f(x) must be in the form of p/q, where p is a factor of the constant term and q is a factor of the leading coefficient.

To find the possible rational zeros for the given function f(x)=-5x^(4)-4x^(3)+3x^(2)+5x+10, we need to list the factors of the constant term (10) and the factors of the leading coefficient (-5).

Factors of 10: ±1, ±2, ±5, ±10
Factors of -5: ±1, ±5

Now, we can list all possible rational zeros by taking each factor of the constant term and dividing it by each factor of the leading coefficient:

Possible rational zeros: ±1/1, ±2/1, ±5/1, ±10/1, ±1/5, ±2/5, ±5/5, ±10/5

The probability that the height of a randomly selected tree is as tall as mine or shorter is 0.1151. The probability that the full height of a randomly selected tree is at least as tall as hers is 0.0362.

To find the probability that the height of a randomly selected tree is as tall as yours or shorter, we need to find the z-score for your tree's height and use the standard normal table to find the corresponding probability. The z-score is calculated as follows:

z = (x - μ) / σ

where x is the observed value, μ is the mean, and σ is the standard deviation.

For your tree, the z-score is:

z = (44.7 - 56.6) / 9.9 = -1.198

Using the standard normal table, the probability that the height of a randomly selected tree is as tall as yours or shorter is 0.1151.

For your neighbor's tree, the z-score is:

z = (74.4 - 56.6) / 9.9 = 1.798

Using the standard normal table, the probability that the height of a randomly selected tree is at least as tall as hers is 1 - 0.9638 = 0.0362.

Purchasing 3 points and reducing their interest rate, Lenny and Lisa will save 84,541.84 in interest over the life of the loan.

To calculate the break-even point on their mortgage, we need to determine how much Lenny and Lisa paid for the points and how much they save on their interest rate over the life of the loan.

First, we need to determine how much Lenny and Lisa paid for the points. One point is equal to 1% of the total loan amount, so 3 points is equal to 3% of 675,250:

3 points = 3% x 675,250 = 20,257.50

Next, we need to calculate how much Lenny and Lisa save on their interest rate by purchasing the points. Their original interest rate was 7.25%, but they were able to reduce it to 6.875% by purchasing 3 points. This means they save 0.375% on their interest rate.

To calculate how much they save over the life of the loan, we need to use an amortization schedule. An amortization schedule shows how much of each payment goes towards interest and how much goes towards principal, and it also shows the remaining balance on the loan after each payment.

Using an online mortgage calculator, we can generate an amortization schedule for Lenny and Lisa's loan. Based on this schedule, they will pay a total of 931,231.40 in interest over the life of the loan if they keep their original interest rate of 7.25%. If they reduce their interest rate to 6.875%, they will pay a total of 846,689.56 in interest over the life of the loan.

This means that by purchasing 3 points and reducing their interest rate, Lenny and Lisa will save 84,541.84 in interest over the life of the loan.

To determine the break-even point on their mortgage, we divide the cost of the points by the amount they save on their interest rate per year.

Answer:

Mai is correct. We can use exponential notation to represent the number of coins each day. Let's call the number of coins on the first day "1". Then the number of coins on each subsequent day is twice the number of coins on the previous day. So we have:

Day 1: 1

Day 2: 2 = 2^1

Day 3: 4 = 2^2

Day 4: 8 = 2^3

...

Day n: 2^(n-1)

To find the number of coins Mai has on the 6th day, we substitute n = 6 into the formula for the number of coins:

Day 6: 2^(6-1) = 2^5 = 32

So Mai has 32 coins on the 6th day. Writing out the product of 2's (1.2.2.2.2.2.2) is equivalent to writing 2^6 = 32.

To find out how many coins Mai has after 28 days, we substitute n = 28 into the formula for the number of coins:

Day 28: 2^(28-1) = 2^27 = 134,217,728

So after 28 days, Mai has 134,217,728 coins.

Answer:

An exponential function in the form of y = a(m) x is of the form:

y = a * m^x

where "a" is a constant, "m" is a positive constant (the base of the exponential), and "x" is the independent variable.

To determine the exponential function in this form, you need to have some information about the function, such as its value at a particular point or its rate of growth.

Here are the general steps to determine the exponential function in the form of y = a(m) x:

Determine the value of "a" by plugging in the known value of "y" and "x" into the equation.

Determine the value of "m" by solving for it using the given information.

For example, let's say you are given that the function passes through the point (2, 8) and has a growth rate of 3. To determine the exponential function in the form of y = a(m) x, you would follow these steps:

Plug in the values of x and y into the equation:

8 = a * m^2

Solve for "a" by isolating it on one side of the equation:

a = 8 / m^2

Use the given growth rate of 3 to find the value of "m":

m = 1 + r = 1 + 0.03 = 1.03

Plug in the value of "m" and the value of "a" you found in step 2 into the equation:

y = (8 / 1.03^2) * 1.03^x

Simplifying this equation gives:

y = 7.514 * 1.03^x

So the exponential function in the form of y = a(m) x that passes through the point (2, 8) and has a growth rate of 3 is y = 7.514 * 1.03^x.

Step-by-step explanation:

here is a more detailed explanation of the steps involved in determining an exponential function in the form of y = a(m) x:

Determine the value of "a" by plugging in the known value of "y" and "x" into the equation.

In the equation y = a(m) x, "a" is a constant that represents the value of y when x is equal to 0. So to find the value of "a", we need to know the value of y for a specific value of x, other than 0.

To find the function values, we need to substitute the given values of x into the function:

a) f(2) = 95(0.84)^2 ≈ 66.96

This means that after 2 hours, there are approximately 66.96 milligrams of medicine remaining in the person's bloodstream.

b) f(6) = 95(0.84)^6 ≈ 35.33

This means that after 6 hours, there are approximately 35.33 milligrams of medicine remaining in the person's bloodstream.

To determine an appropriate domain for the function, we need to consider the context of the problem. The function represents the amount of medicine remaining in a person's bloodstream after taking a dose of medication, so the domain should be the set of non-negative real numbers, since the amount of medicine cannot be negative and time cannot be negative. Therefore, an appropriate domain for the function is [0, ∞).

Interpretation: The function f(x) = 95(0.84)^x models the amount of medicine, in milligrams, remaining in a person's bloodstream after x hours of taking the medication. For example, after 2 hours, there are approximately 66.96 milligrams of medicine remaining in the person's bloodstream.

After taking a dose of medication, the amount of medicine remaining in a person's bloodstream, in milligrams, after x hours can be modeled by the function

We can begin by isolating the variable h on one side of the inequality. First, we can add 10 to both sides:

-10 + 10 - 66h ≥ -3 + 10

Simplifying, we get:

Step-by-step explanation:

If the ground already has an elevation of  15 degree. The degree that the ladder need to be set is 65.4 degrees.

Angle at which the ladder is set from the horizontal =  x.

Angle between the ladder and the ground =  (75 - 15 + x) degrees

Using trigonometry, we can write the equation:

tan(75 - 15 + x) = 10 / L

where:

L=  length of the ladder.

Simplifying the left-hand side using the trigonometric identity for the tangent of the difference of two angles, we get:

tan(60 + x) = 10 / L

Multiplying both sides by L, we get:

L * tan(60 + x) = 10

Dividing both sides by tan(60 + x), we get:

L = 10 / tan(60 + x)

Using a calculator, we can evaluate the right-hand side to be:

L = 10 / tan(60 + x) ≈ 5.768 / tan(x)

So, the equation we need to solve for x is:

5.768 / tan(x) = L

Substituting the value of L obtained from the previous problem, we get:

5.768 / tan(x) = 2.68

Multiplying both sides by tan(x), we get:

5.768 = 2.68 tan(x)

Dividing both sides by 2.68, we get:

tan(x) ≈ 2.153

Using a calculator, we can find the value of x that satisfies this equation by taking the inverse tangent (tan^-1) of both sides:

x ≈ 65.4 degrees

Therefore, the ladder needs to be set at an angle of approximately 65.4 degrees from the horizontal in order to reach a height of 10 feet when the ground already has an elevation of 15 degrees and the ladder is placed at a 75-degree angle with the ground.

Assuming that the expression is meant to be written as:

(a^5 ⋅ 2^3)^3

We can simplify it using the rules of exponents. First, we can simplify the expression inside the parentheses:

a^5 ⋅ 2^3 = a^5 ⋅ 8 = 8a^5

Now we can substitute this simplified expression into the original expression:

(8a^5)^3

To simplify this, we use the power rule of exponents, which states that when we raise a power to another power, we multiply the exponents:

(8a^5)^3 = 8^3 ⋅ (a^5)^3 = 512a^15

Therefore, the simplified expression is 512a^15.
