Richard will increase the amount of time he studies each night by 25%.

The percentage is defined as a ratio expressed as a fraction of 100.

To find the percentage increase, we need to first find the difference between the two amounts of time.

In this case, the difference is 50 minutes - 40 minutes = 10 minutes.

Next, we need to divide the difference by the original amount of time and multiply by 100% to express the answer as a percentage.

In this case, the percentage increase is :

⇒ (10 / 40) x 100% = 25%.

Therefore, he will increase the amount of time he studies each night by 25%.

The function f is guaranteed by the extreme value theorem to have an absolute maximum and an absolute minimum on the closed interval a. [-5, 5].

The extreme value theorem states that if a function f is continuous on a closed interval [a, b], then it must have both an absolute maximum and an absolute minimum on that interval. Since the function f is given as being defined on the closed interval [-5, 5], it must have both an absolute maximum and an absolute minimum on this interval.

We can check that the function f is continuous on the interval [-5, 5] as follows:

First, we need to check that the function is defined at every point in the interval. The function f is defined as f(x) = x+4/(x-1)(x+3). The only points at which this function is not defined are x = 1 and x = -3, which are not within the interval [-5, 5]. Therefore, the function is defined at every point in the interval.

The principal that would need to be invested is  $4202.

We know that the principal has to  do with the amount of money that you have to invest so as to be able to obtain an interest. The interest in this case is a simple interest and it is charged on the principal. The amount is the sum of the principal and the interest.

We now have;

A = I + P

A = amount

I = interest

P = principal

But I = PRT/100

R = rate

T = time

We have;

A = PRT/100 + P

5000 = P * 9.5 * 2/100 + P

5000 = 19P/100 + P

5000 = 19P + 100P/100

The smallest leg of the triangular garden is 5 feet while the biggest leg is 12 feet.

The three-sided shape known as a triangle is sometimes used to allude to it.

The area of a triangle is defined as (1/2) base height, and the sum of all three angles within a triangle will be 180°.

As the given triangular garden has been drawn below,

By Pythagoras' theorem,

x² + (x + 7)² = (x + 8)²

x² + x² + 49 + 14x = x² + 64 + 16x

x² - 2x - 15 = 0

x² - 5x + 3x - 15 = 0

x(x - 5) + 3(x - 5) = 0

(x + 3)(x - 5) = 0

x = -3,5

Since length can never be negative thus x = 5.

The smallest leg = 5 feet

Biggest leg = 5 + 7 = 12 feet

Hence "The triangular garden's smallest leg is 5 feet long, while its longest leg is 12 feet".

Answer:

A.) Yes, because 0.064 is less than 0.4

Step-by-step explanation:

The equation [tex]0.4^3 = 0.064[/tex] is a counterexample to the given conjecture because 0.064 is less than 0.4. This shows that the cube of a number is not always greater than the number.

In general, the cube of a number is the result of multiplying the number by itself three times. For example, the cube of 2 is [tex]2 * 2 * 2 = 8[/tex], and the cube of 5 is [tex]5 * 5 * 5 = 125[/tex]. The cube of a number is always greater than the number when the number is positive, because a positive number multiplied by itself three times is always a larger number. However, when the number is negative or a decimal, this is not always the case.

In the given equation, 0.4 is a decimal number, and [tex]0.4^3[/tex] is the cube of 0.4. The result of this calculation is 0.064, which is less than 0.4. This means that the cube of 0.4 is not greater than 0.4, and therefore the given conjecture is false.

Total 26, 250 passengers are flew in June in an airline flights between Chicago and Denver .

An Equations with roots , such as the square root cannot be solved until its root is eliminated. Once we have isolated the square root on one side, we can eliminate it by raising both sides of the equation to powers equal to the square root. For example, if the square root is only one-sided, we can square both sides. We have , An airline offers daily flights between Chicago and Denver. Cost function of flight is,

C = 0.2x + 1

where x represents the number of passengers (in thousands) in flight.

To calculate how many passengers flew each day in June, we need to set the function to 2.5 (since the cost is in millions of dollars) and solve for the variables. This means taking the square root equal to 2.5. Therefore, to solve for the variables contained in its square root, we need to square both sides. This process and solution are described below,

√(0.2x + 1) = 2.5

Squaring both sides

=> (√(0.2x + 1) )² = ( 2.5 )²

=> 0.2x + 1 = 6.25

=> 0.2 x = 6.25 - 1 = 5.25

=> x = 5.25/0.2

=> x = 26.25

Now, we know that our variable i.e x measures passengers in thousands, so total passenger flew in June are 26.25 × 1000 = 26, 250 .

c) The monthly payments after consolidating the three loans are $350.69.

d) The total payments over the 22 years period will be $92,581.47.

Note that student loans attract simple interest and not compound interest.

After the bank consolidates it, the interest system changes to compounding.

The total interest is computed by applying the annual percentage rate (APR) to the principal and the loan term.  The result is added to the principal to obtain the total payment for each loan.

The total payment is divided by the loan period to get the monthly payments.

But for the consolidated loan by the bank, we can use an online finance calculator to determine the monthly payments and total payment over the loan term as follows.

Total amount of loans = $43,500 ($12,000 + $18,000 + $13,500)

Bank APR = 8%

Loan term = 22 years

Hence we have -2 is equal to rcosQ and 5 is equal to rsinQ .

Answer:

The ladder rests against the wall at 6ft.

The ladder in Figure 2 rests about 3ft higher than the ladder in Figure 1.

Step-by-step explanation:

We can assume both of the figures display the ladder, ground, and wall forming a right triangle because the assignment is titled "apply the Pythagorean theorem", suggesting we should use the Pythagorean theorem and both figures are right triangles.

The Pythagorean theorem states that the sum of each leg squared is equal to the hypotenuse squared, or a^2 + b^2 = c^2, where "a" and "b" are legs and "c" is the hypotenuse.

At what height does the ladder in Figure 1 rest on the wall?

First, identify which sides are the legs and which is the hypotenuse. The hypotenuse is always the longest side and is the side opposite from the right angle. Thus, the hypotenuse in Figure 1 is the ladder length, and the two legs are the distance the ladder is from the wall and the height of the ladder against the wall. In other words, c = 10, a = 8, and b = the missing side length. Now, plug in the values to the Pythagorean theorem:

8^2 + b^2 = 10^2

64 + b^2 = 100

b^2 = 36

b = 6

The height at which the ladder in Figure 1 rests on the wall is 6 ft.

Approximately how much higher up the wall does the ladder in Figure 2 rest compared to the ladder in Figure 1?

We can set up the equation: Figure 2 ladder height - Figure 1 ladder height. We already know how where the ladder height of Figure 1 is, so we only need to solve for the ladder height in Figure 2 to get the result. Applying the same method as in the previous problem, we can input the values of Figure 2 into the Pythagorean theorem:

4^2 + b^2 = 10^2

16 + b^2 = 100

b^2 = 84

b = sqrt84

b ~ 9 ft

Now, we can find the difference between the Figure 2 ladder height and Figure 1 ladder height to get the answer to the question:

9 ft - 6 ft = 3 ft
