The number of fruits that Kim bought in all, given the apples and oranges was ;

Let's call the number of oranges that Kim bought "O" and the number of apples that Kim bought "A".

From the problem, we know that Kim bought fewer than 20 pieces of fruit, so we can write:

A + O < 20

A = O + 3

Simplifying:

2O + 3 < 20

2O < 17

O < 8.5

Since O represents the number of oranges, we know that Kim bought fewer than 8.5 oranges. Since she can't buy a fraction of an orange, this means that she must have bought either 8 oranges or fewer.

Now we can use the equation A = O + 3 to find the number of apples she bought:

A = 8 + 3 = 11

So Kim bought 8 oranges and 11 apples.

The value of cos J rounded to the nearest hundredth is 0.384.

A mathematical function known as the cosine is used in many branches of mathematics, such as geometry and trigonometry. It is described as the proportion between the hypotenuse and the adjacent side of a right triangle. It is represented by the symbol cos-1 or arc cos and is also known as the inverse cosine or arc cosine.

Using Pythagoras theorem lets find IJ

IJ = [tex]\sqrt{13^2 - 12^2}[/tex]

IJ = √25

IJ = 5

The probability of no one getting a hole in one on the sixth hole during the 1989 U.S. Open golf tournament is 0.95431 and the probability of exactly one golfer getting a hole in one on the sixth hole is 0.04478.

The probability of an event occurring is the number of favorable outcomes divided by the number of possible outcomes. In this case, the probability of a professional golfer making a hole in one is 1/3,709.

a. To find the probability that no one gets a hole in one on the sixth hole, we need to find the probability that each of the 174 golfers does not get a hole in one. The probability of not getting a hole in one is 1 - (1/3,709) = 3,708/3,709. The probability that no one gets a hole in one is (3,708/3,709)^174 = 0.95431. Therefore, the probability that no one gets a hole in one on the sixth hole is 0.95431.

b. To find the probability that exactly one golfer gets a hole in one on the sixth hole, we need to find the probability that one golfer gets a hole in one and the rest do not. The probability of one golfer getting a hole in one is 1/3,709 and the probability of the rest not getting a hole in one is (3,708/3,709)^173. There are 174 ways this can happen, so the probability is 174 * (1/3,709) * (3,708/3,709)^173 = 0.04478. Therefore, the probability that exactly one golfer gets a hole in one on the sixth hole is 0.04478.

In conclusion, the probability of no one getting a hole in one on the sixth hole during the 1989 U.S. Open golf tournament is 0.95431 and the probability of exactly one golfer getting a hole in one on the sixth hole is 0.04478.

Step-by-step explanation:

The nearest percent, the percent decrease in clock cycles after optimization is approximately 87%.

Optimization is the process of improving the performance or efficiency of a system, process, or algorithm by finding the best possible solution within a given set of constraints or limitations.

The percent decrease in clock cycles after optimization can be calculated using the formula:

Percent decrease = [(original value - new value) / original value] x 100%

where the original value is the number of clock cycles required before optimization, and the new value is the number of clock cycles required after optimization.

Using the given values, we have:

Percent decrease = [(450 - 60) / 450] x 100%

= (390 / 450) x 100%

= 86.67%

The total number of dimes in the container is 6 while the total number of quarters is 11.

To solve this problem, we will be using the simultaneous equation. The dimes and quarters will be assigned some figures:

First:

d + q = 17

10d + 25q = 335

This second equation is so because the value of the coins was converted to cents.

Where $1 = 100 cents

Next, we will resolve the figures to get the values for d and q as follows:

Multiply both sides of the first equation by -10

-10d - 10q = -170

Now, we shall minus the first equation from the second one to give:

15q = 165

q = 165/15

= 11

Substitute the value of q in the first equation:

The function of the power series f(x) = 6ln(1+x) = ∑=1 , ∞ 6(-1)⁽ⁿ⁻¹⁾xⁿ/n.

And a_n = 6(-1)⁽ⁿ⁻¹⁾xⁿ/n.

The common ratio is the distance between each number in a geometric series. The proportion of a number or two consecutive numbers. The common ratio, which is the same for all numbers or common, is the number divided by the number that comes before it in the sequence.

To find the power series for f(x), we first need to find the power series for g(x) = 6/(1+x):

g(x) = 6/(1+x) = 6(1 - x + x² - x³ +...) (geometric series with common ratio -x)

Next, we integrate term by term:

∫ g(x) dx = ∫ 6(1-x+x²-x³+...) dx

= 6(x - x²/2 + x³/3 - x⁴/4 + ...) + C , where C is a constant.

Since we're only interested in finding the coefficients of the power series, we can ignore the constant term.

Thus, the power series for f(x) is:

f(x) = 6ln(1+x) = 6(x - x²/2 + x³/3 - x⁴/4 + ...) = ∑=1 , ∞ 6(-1)⁽ⁿ⁻¹⁾xⁿ/n

where a_n = 6(-1)⁽ⁿ⁻¹⁾xⁿ/n.

To find the exact values of all six trigonometric functions of 660°, we need to first convert the angle to one that falls within the range of 0° to 360°. We can do this by subtracting 360° from the given angle until we get a value within the desired range.

660° - 360° = 300°

Now we can find the exact values of the trigonometric functions of 300° using the unit circle:

sin 300° = -√3/2
cos 300° = 1/2
tan 300° = -√3
csc 300° = -2/√3
sec 300° = 2
cot 300° = -1/√3

Therefore, the exact values of all six trigonometric functions of 660° are:
sin 660° = -√3/2
cos 660° = 1/2
tan 660° = -√3
csc 660° = -2/√3
sec 660° = 2
cot 660° = -1/√3

Problem 6: Verify the identity: sin x + cos x cotx = CSC X.

To verify this identity, we can start by simplifying the left-hand side of the equation:

sin x + cos x cotx
= sin x + cos x (cos x / sin x)
= sin x + (cos^2 x / sin x)
= (sin^2 x + cos^2 x) / sin x

Since sin^2 x + cos^2 x = 1, we can simplify further:

= 1 / sin x
= csc x

Therefore, the left-hand side of the equation simplifies to the same value as the right-hand side, verifying the identity.

If you put your hand on a hot stove and got burnt, it is a natural response to remove your hand from the stove to prevent further injury. However, if you choose to repeatedly put your hand back on the stove even after being burnt, you will continue to experience pain and potentially cause further damage to your skin and tissues.

Repeatedly exposing yourself to the source of the burn will not change the fact that it is hot and causing damage to your skin. In fact, each time you touch the hot surface, you are likely to make the burn worse, as the heat will continue to damage your skin and tissues.

Additionally, repeated exposure to the hot stove may lead to nerve damage, which can result in a loss of sensation in your hand, making it harder to recognize when you are in danger of burning yourself in the future.

It is important to listen to your body's natural responses to pain and remove yourself from harmful situations. In the case of a burn, it is best to seek immediate medical attention and follow proper first aid procedures to minimize damage and promote healing.

You will have 4500L of water in the tank after it rains 90mL.

If it rains 90mL and you have a tank with a roof area of 50m^2, you can calculate the amount of water collected in the tank using the following formula:

Amount of water collected = (Rainfall in mm) x (Roof area in m^2)

In this case, the amount of water collected would be:

Amount of water collected = (90mm) x (50m^2)

Since 1mm of rain is equivalent to 1L of water per square meter, we can convert the rainfall from mm to L:

Amount of water collected = (90L/m^2) x (50m^2)

Simplifying the equation gives us:

Amount of water collected = 4500L
