2. An Olympic sized pool holds 6.6 x 105 gallons. How many liters is that? (1 gallon = 3.79 Liters)
a. 1.7 x 105 L
b. 2.5x 106 L
c. 1.7 x 104 L
d. 2.5 x 107 L

The length of side b of the given right angle triangle using law of sines is; b = 12.044 m

The law of sines states that when we divide side "a" by the sine of angle A, it is equal to side "b" divided by the sine of angle B, and also equal to side "c" divided by the sine of angle C

Thus;

a/sin A = b/sin B = c/sinC

The parameters are;

B = 42°

c = 18m

Since c is the hypotenuse, it is the side that will be opposite the right angle and so;

C = 90°

Thus, using sine rule;

c/sinC = b/sin B

18/sin 90 = b/sin 42

b = (18 * sin 42)/1

b = 12.044 m

The probability that it will snow on both days, given the chances of snow on Saturday and Sunday, is 24.5%.

The chance of it snowing on both days is calculated by multiplying the probability of it snowing on Saturday by the probability of it snowing on Sunday. If the probabilities are independent, we can assume that one event occurring doesn't affect the other event, therefore the probability of both events happening is just the product of the individual event probabilities.

So, the chance of it snowing on both days is:

P(Saturday and Sunday) = P(Saturday) x P(Sunday)

P(Saturday and Sunday) = 0.35 x 0.70

P(Saturday and Sunday) = 24.5 %

The lighthouse is 8.88 m tall.

What is the ratio?

A ratio is a mathematical comparison of two or more quantities. It expresses the relationship between the values of the quantities in terms of a numerical fraction.

This problem can be solved using similar triangles. Since the ratio of the heights of Pythagoras and the lighthouse is the same as the ratio of their corresponding shadow lengths, we can set up the following proportion:

(Height of lighthouse) / (Height of Pythagoras) = (Shadow length of lighthouse) / (Shadow length of Pythagoras)

Plugging in the given values:

(Height of lighthouse) / 1.78 = 26 / 3.08

To solve for the height of the lighthouse, we can cross-multiply and divide:

(Height of lighthouse) = (26 / 3.08) * 1.78

The lighthouse is approximately:

(26/3.08)*1.78 = 8.88 m

The interval on which the profit function is increasing is [0, 25).

Given that:

The cost function is, C(x) = 1.2x - 0.012x²

The revenue function is, R(x) = 3.6x - 0.06x²

Here, x i is the number of units sold, and 0 ≤ x ≤ 150.

The profit function is:

P(x) = R(x) - C(x)

      = (3.6x - 0.06x²) - (1.2x - 0.012x²)

      = 2.4x - 0.048x²

Find P'(x).

P'(x) = 2.4 - 0.096x

The profit function is increasing when P'(x) > 0.

2.4 - 0.096x > 0

2.4 > 0.096x

When an algebraic equation is graphed, it always results in a straight line since each term in a linear equation has an exponent of 1. For this reason, it is referred to as a "linear equation."

There are both one-variable and two-variable linear equations.

Given One canned juice drink is 30% orange juice, another is 5% orange juice,

Let x and y be the amount of 30% and 5% orange juice respectively,

according to condition

0.30x + 0.05y = 0.27(25) .........(1)

x + y = 25.........(2)

Multiply the second equation by -0.05,

0.30x + 0.05y = 0.27(25)

-0.05x - 0.05y = -0.05(25)

Add equation to eliminate y,

0.30x - 0.05x + 0.05y - 0.05y = 0.27(25) - 0.05(25)

Solve for y,

0.25x = 5.5

x = 5.5/.25

x = 22

substitute value of x in equation,

x + y = 25

(22) + y = 25

Answer:

You have let out 48.5 feet of string

Step-by-step explanation:

Attached is a sketch of the problem.

We can use SOH CAH TOA to find our answer.

In this acronym, O is the opposite side, A is the adjacent side, and H is the hypotenuse. S is for the SIN function. C is for the COS function. T is for the TAN function.

We can calculate the length of the string by using the SIN function.

So we can say the sine of angle x is the opposite side divided by the hypotenuse.

[tex]sin(x)=\frac{O}{H}[/tex]

Lets solve for [tex]H[/tex].

Multiply each term by [tex]H[/tex].

[tex]H*sin(x)=\frac{O}{H} *H[/tex]

Simplify the right side by cancelling the common factor of [tex]H[/tex].

[tex]H*sin(x)=O[/tex]

Divide both sides of the equation by [tex]sin(x)[/tex].

[tex]\frac{H*sin(x)}{sin(x)} =\frac{O}{sin(x)}[/tex]

Simplify the right side by cancelling the common factor of [tex]sin(x)[/tex].

[tex]H=\frac{O}{sin(x)}[/tex]

Now lets evaluate the length of the string.

In this example we are given

[tex]x=68\\O=45[/tex]

[tex]H=\frac{45}{sin(68)}[/tex]

[tex]H=48.5341[/tex]

The average speed is 0 m/s since the object does not move.

Since the object does not change its position, it does not move. Therefore, its average speed is 0 m/s.

The object in question does not move in a closed path, meaning that its position remains the same throughout the entire path. As a result, its average speed is 0 m/s. This is because average speed is the total distance traveled divided by the total time taken, and since the object does not move its distance traveled is 0 and its time taken is also 0. Therefore, when the object goes around the closed path, its average speed is 0 m/s.

Speed is defined as the length traveled by a particle or entity in an hour. It is a scale parameter. It is the ratio of length to duration.

We know that the speed formula

Speed = Distance/Time

Sound travels about 750 miles per hour. If you stand in a canyon and sound a horn, you will hear an echo.

Convert the speed in feet per second. Then we have

Speed = 750 x 5280 / 3600

Speed = 1,100 feet per second

Let 'n' be the number of seconds. Then the distance is given as,

1,100 = (d / 2) / n

d = 2,200 n

If n = 1.5, then we have

What is probability?

Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one. Probability has been introduced in Maths to predict how likely events are to happen. The meaning of probability is basically the extent to which something is likely to happen. This is the basic probability theory, which is also used in the probability distribution, where you will learn the possibility of outcomes for a random experiment. To find the probability of a single event to occur, first, we should know the total number of possible outcomes.

Probability of event to happen P(E) = Number of favourable outcomes/Total Number of outcomes

Now,

2004 to 2006: (12,440 - 8,574) / (2006 - 2004) = 3,866 / 2 = 1,933 locations/year

2006 to 2007: (15,006 - 12,440) / (2007 - 2006) = 2,566 / 1 = 2,566 locations/year

2005 to 2006: (12,440 - 10,238) / (2006 - 2005) = 2,202 / 1 = 2,202 locations/year

b. To estimate the instantaneous rate of growth in 2006, we can take the average of the last two rates of change from part (a).

(2,566 + 2,202) / 2 = 2,384 locations/year

c. To estimate the instantaneous rate of growth in 2006 by measuring the slope of the tangent line through (2005, 10,238) and (2007, 15,006), we can use the formula:

(15,006 - 10,238) / (2007 - 2005) = 4,768 / 2 = 2,384 locations/year

d. To estimate the instantaneous rate of growth in 2007 by measuring the slope of the tangent line through (2006, 12,440) and (2008, 16,676), we can use the formula:

(16,676 - 12,440) / (2008 - 2006) = 4,236 / 2 = 2,118 locations/year

4x – 3y = -31

To find x or method, you must first make one of the words the same so that they may cancel out.

To determine the x terms, we will make the y terms the same in this example.

To do so, multiply the first equation by three, yielding:

18x – 6y = - 42

And multiply the second equation by two to get:

8x – 6y = - 62

Now that we have the y terms, you may cancel them out.

You now have the following two equations:

18x = -42

8x = -62

The next step is to combine them, since the preceding – and – form a +.

This implies that you are left with one equation

26x = -104

Now divide by 26 on each side to get:

x = -4

As you have x, you substitute it into one of the ORIGINAL equations.

6x – 2y = -14

Substitute x in:
