By using trigonometry, it can be calculated that-

Distance from the top of the tree to the tip of the shadow is 15.46 feet

What is Trigonometry?

Trigonometry shows the relationship between sides and angles of a right angled triangle.

There are six trigonometrical functions

[tex]sin \theta, cos \theta, tan \theta, cot \theta, sec \theta, cosec \theta[/tex]

[tex]sin \theta = \frac{Perpendicular}{Hypotenuse}\\\\cos \theta = \frac{Base}{Hypotenuse} \\\\tan \theta = \frac{Perpendicular}{Base} \\\\cot \theta = \frac{Base}{Perpendicular} \\\\sec \theta = \frac{Hypotenuse}{Base} \\\\cosec \theta = \frac{Hypotenuse}{Perpendicular} \\\\[/tex]

Let the angle of elevation be [tex]\theta[/tex] and distance from the top of the tree to the tip of the shadow be d feet

Here the tree represents the perpendicular, shadow represents the base and distance from the top of the tree to the tip of the shadow represents the hypotenuse

A tree that is 15 feet tall casts a shadow that is 4 feet long

[tex]tan\theta = \frac{15}{4}\\\theta = tan^{-1}( \frac{15}{4})\\\theta = 75.1^{\circ}[/tex]

Now,

[tex]sin75.1^{\circ} = \frac{15}{d}[/tex]

[tex]0.97 = \frac{15}{d}\\d = \frac{15}{0.97}\\d = 15.46 \ feet[/tex]

1). If the algae doubles every day, it will take 15 days for it to cover half the lake. This means it would happen on January 15.

2). Your friend may be skeptical because they may not believe that the algae can grow so quickly and cover the entire lake in just 30 days. Alternatively, they may not believe that you have accurate information about the situation.

3). Removing most of the algae on January 29 would significantly reduce the amount of algae in the lake and would likely help prevent the lake from becoming completely covered. However, if 1% of the surface is still covered with algae on February 1, it is possible that the problem has not been fully solved and the algae could continue to grow and potentially become a problem again in the future. It would be best to continue monitoring the lake and taking action to prevent the algae from growing.

The polar equation for the curve is x = √3cosФ and y = √3 sinФ.

Here we have to find the polar equation of the curve.

Data given:

The equation is:

x² + y² = 3

This is an equation of a circle.

Its radius is √3 and its √center is (0,0)

To find the polar equation of a circle we use the following formula:

x = h + rcosФ

y = k + r sinФ

where (h,k) is the center of the circle which in this case is (0,0) and by substituting we get:

x = √3 cosФ

y = √3 sinФ

Therefore the polar equation is x =√3cosФ and y = √3sinФ.

If we roll a dice three times and we can stop in the first time only when it come 6. The expected payoff is 4.557.

According to the question:

The number of times you can get 06 are:

(i). If the third toss rolls a 6:  6

In this case her first two digits can be any of the five numbers. No. The number of cases is 5 × 5 = 25.

(ii). If you get a 6 on the second throw. The number of cases is -5 (no third throw in this case)

(iii). If the first roll rolls a 6. The number of cases is -1.

2. Number of times you can get 5 Are-

(i). If there is only one 5 in 3 rolls . The number of cases will simply be

3 × 4 × 4

(Because there are 5 possibilities in 3 places and 4 in the remaining places.)

(ii). If there are two 5s, the number of cases is 3×4. (Because there are 3 places where 5 cannot exist, and the places are filled with 4 possibilities.)

(iii). If there are three 5s, the number of possibilities is -1.

Similarly, for 4,3,2,1, the number of possibilities is (3*3*3 + 3*3 + 1), (3*2*2 + 3*2 + 1), (3 × 1×1 + 3×1 + 1), 1 each.

So the number of possibilities for 1,2,3,4,5,6 are 1,7,19,37,61,31 respectively .

You can now get the expected profit by taking the weighted average of the numbers with the possible outcome odds.

So the result is (6*31 + 5*61 + 4*37 + 3*19 + 2*7 + 1)/(31+61+37+19+7+1)

Part A) If the original price of the model car was $40, and it was sold on the third day, with a daily discount of 5%, the sales amount is $34.30.

Part B) The percentage discount from the original price is 14%.

The percentage discount is the total discount divided by the original price multiplied by 100.

In this instance, we compute the total discount as $5.70, then express this value as a numerator with $40 as the denominator.  The quotient is multiplied by 100.

Original price of the model car = $40

Daily discount = 5%

The date the car sells = the third day

The sales price on the third day = $34.30 ($40 x 95% x 95% x 95%)

Total discounts = $5.70 ($40 - $34.30)

Answer:

In an exponential equation, both sides can be written as power of the same base when the base is the same on both sides of the equation. For example, the equation "2^x = 8" can be rewritten as "2^x = 2^3" because the base, 2, is the same on both sides of the equation.

To solve an exponential equation where both sides can be written as powers of the same base, you can set the exponents equal to each other and solve for the variable. In the example above, setting the exponents equal to each other would give us "x = 3", so the solution is x = 3.

On the other hand, in an exponential equation where both sides can not be written as powers of the same base, you cannot simply set the exponents equal to each other. Instead, you need to use a different method to solve the equation. One way to do this is to use the property of exponents that states that "a^x * a^y = a^(x+y)" to rewrite the equation so that both sides have the same base. For example, the equation "2^x * 3^y = 6" can be rewritten as "2^x * 2^(log3(6)) = 2^(x + log3(6))", where "log3" represents the logarithm with base 3. This allows us to set the exponents equal to each other, giving us "x + log3(6) = 1", and we can solve for x to find the solution.

Answer: B.83

Answer: B.83

Step-by-step explanation:

The number 2,158 is called the numerator or dividend, and the number 26 is called the denominator or divisor.

The quotient of 2,158 and 26, the ratio of 2,158 and 26, as well as the fraction of 2,158 and 26 all mean (almost) the same:

2,158 divided by 26, often written as 2158/26. 2,158 divided by 26 = 83

The result of 2158/26 is an integer, which is a number that can be written without decimal places.

   2158 divided by 26 in decimal = 83

   2158 divided by 26 in fraction = 2158/26

   2158 divided by 26 in percentage = 8300%

The solution of the given inequality -3/2(y/6 + 4) < -2x will be 8x - y < 24.

A difference between two values indicates whether one is smaller, larger, or basically not similar to the other.

In other words, inequality is just the opposite of equality for example 2 =2 then it is equal but if I say 3 =6 then it is wrong the correct expression is 3 < 6.

As per the given,

-3/2(y/6 + 4) < -2x

-3y/12 - 6 < -2x

2x - 3y/12 < 6

24x - 3y < 72

The location of the circumcenter, of the obtuse triangle, which is the center of the circle that inscribes the triangle is at a point lower than the base of the triangle, and therefore, outside the triangle, because the angle of the arc formed by the base at the center is larger than 180°, which is the angle formed by the diameter/ The correct option is option c.

c. Outside the triangle

The circumcenter is the point of intersection of the perpendicular bisectors of the sides of the triangle.

The location of the circumcenter can be inside the triangle, outside the triangle, or on the triangle.

The circumcenter is located on the inside of an acute triangle, while it is located on the hypotenuse side of a right triangle.

The circumcenter is the location of the center of the circle that circumscribe the triangle, such that in an acute triangle, the angle at the center (twice the angle at the circumference), is always less than 180°, which is the angle made by the diameter, which keeps the diameter line and the circumcenter, passing inside the triangle.

However, in an obtuse triangle, the angle at the center, is larger than 180°, such that the line joining the base of the triangle, inscribed in the circle is located above the diameter, and therefore, located above the circumcenter.
