The equations that could be used to solve for the unknown lengths of △ABC are cos45° = AC/9 and sin45° = BC/9.

We know a right-angled triangle has three sides they are -: Hypotenuse,

Opposite and Adjacent.

We can remember SOH CAH TOA which is,

sin = opposite/hypotenuse, cos = adjecent/hypotenuse and

tan = opposite/adjacent.

The opposite side to the reference angle is BC and the adjacent is the height.

We know, cos = adjacent/hypotenuse

There are 2,118,760 possible ways to select 6 cards from a deck of 52 cards if the spade ace must be selected.

If at all you must select the spade ace, you have 51 cards remaining from which to choose 5 more cards. The number of ways to choose 5 cards from 51 is 51C5, where C represents the number of combinations.

Using the formula for combinations, we have:

51C5 = 51! / (5! * (51 - 5)!) = 51! / (5! * 46!)

Using the factorial we can simplify this expression to:

51C5 = 51 * 50 * 49 * 48 * 47 / (5 * 4 * 3 * 2 * 1) = 2,118,760

The amplitude, period, and zero value of the function y = 3cos(x+5) are (A) 3, 2π, later.

Option D is correct.

The amplitude of a cosine function is described  as half the difference between the maximum and minimum values of the function.

In the question given, the maximum value of the function y = 3cos(x+5) is 3 and the minimum value is -3, hence amplitude is:

A = (3 - (-3)) / 2 = 3

For a cosine function with a period of 2π, the maximum or minimum values repeat every 2π units along the x-axis.

In the question above, the period of the function y = 3cos(x+5) is:

P = 2π

in conclusion, the phase shift of a cosine function is the horizontal shift of the graph of the function along the x-axis, which is represented by the constant term (x+5) in this case.

So if there were -4+20 the answer would be 16. When you add things, it goes to the right of the number line. When you subtract stuff it goes to the left. Simple but there are more rules like when this happens: 6--4 the two minuses turn into a plus 6+4—and other stuff. So -8 you have 8 negative signs and 20 positive signs. When a positive and a negative are added together they cancel each other out so now you have 12. This is modeled on the attachment. Hope this helped!

The distance of the parking lot from the first campsite is 3.14 miles.

The scale of the map is 1/24,000, which means that for every 1 inch on the map, it is equal to 24,000 inches in reality. To calculate the distance of the parking lot from the first campsite, we need to first convert the 8.3 inches on the map into inches in reality. To do this, we use the formula:

Actual distance = Map distance x (Map scale)

Actual distance = 8.3 inches x 24,000 inches

Actual distance = 199,200 inches

Now, to convert inches to miles, we can use the formula:

Miles = Inches / 63360

Miles = 199,200 inches / 63360

Miles = 3.14 miles

Therefore, the distance of the parking lot from the first campsite is 3.14 miles.

A student taking thirteen credit hours should plan for approximately 13-15 hours of work outside of class each week.

Generally, if a student is taking thirteen credit hours, they should plan for approximately 13-15 hours of work outside of class each week. This includes attending lectures, studying, and completing assignments. To calculate this, the student should take the total number of credit hours (13) and multiply it by the number of hours per credit (usually 3 hours). This would give the student 39 hours of work outside of class.

However, this number should not be taken as an exact number, as the amount of time needed to complete the course may vary based on the student's learning style, the difficulty of the course, and the amount of time required for each assignment. For example, if a student is taking a particularly difficult course, they may want to plan for more hours than the calculation suggests.

In order to ensure success, students should plan ahead, create a schedule, and stick to it. This will help them stay on track and complete their coursework in a timely manner.

Step-by-step explanation:

First lets find 7% of 96

96 x 0.07 = 6.72

then subtract 6.72 from 96

96-6.72=89.28

The requried, a number that is 7% smaller than 96 is approximately 89.28.

To find a number that is 7% smaller than 96, we need to calculate 7% of 96 and then subtract that value from 96.

Calculate 7% of 96.

7% of 96 = (7/100) * 96 = 0.07 * 96 = 6.72

To get a number that is 7% smaller than 96, we need to subtract the value we found in Step 1 from 96. subtract the calculated value from 96.

Number = 96 - 6.72 = 89.28

The equivalent interest rate will be 0.5 % and it will be compounded 24 times

Compound interest is the interest you earn on interest. This can be illustrated by using basic math: if you have $100 and it earns 5% interest each year, you'll have $105 at the end of the first year. At the end of the second year, you'll have $110.25.

Compound interest is calculated by calculating the Amount

A = P( 1+r/n)^ ntp

A = amount

P is the principal

t is the time elapsed

since the interest rate is 6 % , the. monthly compounded interest will be 6/12, since there is 12 months in a year.

= 0.5 %

the number of times it will be compounded will be 12 × 2 = 24 times

therefore the equivalent interest rate is 0.5% per month and it will be compounded 24 times in the space of 2 years.
