Answer:

x = \(\frac{\pi }{3}\) , \(\frac{2\pi }{3}\) , \(\frac{4\pi }{3}\) , \(\frac{5\pi }{3}\)  

Step-by-step explanation:

sin²x = 3cos²x

\(\frac{sin^2 x}{cos^2 x}\) = 3

tan²x = 3, x ∈ [0, 2π)

tan x = √3 , x ∈ [0, 2π)

Answer:

Option C

The first two hours cost $4. Between two hours and six hours cost $2 per hour, and all hours after that cost $1.

Step-by-step explanation:

From the first part of the graph we can see that there is a flat rate of $4 for the first two hours. So the first two hours cost $4.

We can eliminate options A and B leaving C and D as only possible options.

Look at the second part of the graph

Between 2 hours and 6 hours(difference of 4 hours), the cost increases from $4 to $8 or an increase of $8

So rate per hour is $8/4 = $ 2 per hour between 2 hours and 6 hours

This information alone is enough to eliminate D but let's go to the rate beyond 6 hours just to make sure. This is the third part of the graph

Between 6 and 7 hours (1 hour) we can see the cost goes from $12 to $13 or a difference of $1. This means for every hour after 6 hours, the rate is $1 per hour.

So option C is the correct choice

Step-by-step explanation:

The purchase value of an office computer is $12,500. Its annual depreciation is $1875. then the value of the computer after 6 years is

1250

What is the simple definition of depreciation?

The term depreciation refers to an accounting method used to allocate the cost of a tangible or physical asset over its useful life. Depreciation represents how much of an asset's value has been used.

The value of the computer is decreasing by $1875 annually per year. So the amount of decrease in 6 years is: 6×1875=$11250 6 × 1875 = $ 11250

now

The purchase value of an office computer is $12,500

therefore

12500- 11250

= 1250

Answer:

Step-by-step explanation:

Before: 545, 945, 970, 995 , 1015, 1030 , 1040 , 1124

Now:  905, 945, 970, 995 , 1015, 1030 , 1040 , 1124

a) Median stays same.

As number of data's is 8, median is the average of 4th and 5th term

Median = (995 + 1015)/2 = 2010/2  =

Median = 1005

When rent changes from $545 to $ 905, the 4th and 5th term remains same.

So, median stays same

b) Mean increases 45

Before: 545, 945, 970, 995 , 1015, 1030 , 1040 , 1124

Mean = Sum of rents ÷ 8

= (545 + 945+ 970+ 995 + 1015 +1030 + 1040 + 1124)/8

=7664/8

= 958

Now : 905, 945, 970, 995 , 1015, 1030 , 1040 , 1124

Mean = (905 + 945+ 970+ 995 + 1015 +1030 + 1040 + 1124)/8

         = 8024/8

         = 1003

Mean increases by 1003 - 958 = 45

The value of the probability is P(Large or Blue) = 7/10

The given parameters are represented on the table

Using the table parameters, we have

P(Large or Blue) = [(Large) + (Blue) - (Large and Blue)]/Total

This gives

P(Large or Blue) = ((17 + 8) + (17 +3) - 17)/(17 + 3 + 8 + 12)

This gives

P(Large or Blue) = 28/40

Simplify

P(Large or Blue) = 7/10

Hence, the value of the probability is P(Large or Blue) = 7/10

Answer:

Step-by-step explanation:

Out of the population being surveyed, the one that could result in a sample statistic but not a parameter is; B: 50

A sample statistic is a piece of information you get from a fraction of a population.

A parameter is a number describing a whole population (e.g., population mean), while a statistic is a number describing a sample (e.g., sample mean).

Now, we are told that a population consists of 5000 people. This means that the sample statistic could be the sample mean which could be 50 but certainly not 5000 as the sample statistic can't be same as the population.

and then solve it :)

The exponential function that represents the population r years after 1993 is A(t) = 2600(1.021)^t

From the question, we have the following parameters that can be used in our computation:

Initial population = 2600

Rate of growth = 2.1 percent per year

The above parameters can be represented as

Initial population, a = 2600

Rate of growth, r = 2.1% per year

The exponential function that represents the population r years after 1993 can then be represented as

A(t) = a * (1 + r)^t

Substitute the known values in the above equation, so, we have the following representation

A(t) = 2600 * (1 + 2.1%)^t

Evaluate the sum

A(t) = 2600 * (1.021)^t

So, we have

A(t) = 2600(1.021)^t

Hence, the expression is A(t) = 2600(1.021)^t

The function is an exponential growth function

The function is given as

y=2(1.06)^9

We can begin by rewriting the given equation as:

y = 2 * 1.06t

So, we have

y = 2 * (1 + 0.06)^t

Now we can see that the equation is in the form y = a*b^t,

where a = 2 and b = 1.06^9

This equation represents exponential growth because the base of the exponent, b = 1.06, is greater than 1.

We can re-write it in the form y = a(1+r)t,

we can find the value of r by subtracting 1 from 1.06 which is 0.06 and the value of a is 2.

so we have y = 2(1+0.06)^t

So, the equation represents exponential growth with a = 2 and r = 0.06

c) The answer "night of wor" is not related to the given concept of "100 + 10 = 9 remainder 0." Therefore, the answer is wrong.

d) The learner says that "3 is closer to one" when comparing it to 4. This statement is incorrect because 4 is actually closer to 1 than 3. The learner has misunderstood the concept of closeness or proximity. Therefore, the answer is wrong.

e) The learner says that the number represented by the Dienes blocks is "1 000 100 101." To determine if this answer is right or wrong, we need more information about the representation of Dienes blocks. However, assuming each cube represents a unit, the correct representation of the number should be "1 001." Therefore, the answer is wrong.

A square and a rectangle differ in terms of their properties. A square is a special type of rectangle where all sides are equal, and all angles are right angles. In contrast, a rectangle has opposite sides that are equal, but not necessarily all sides. Both squares and rectangles have four sides, but squares have additional properties that make them unique.

To show two different rectangles with a perimeter of 12 cm, we can consider the following examples:

- Rectangle 1: Length = 3 cm, Width = 3 cm (perimeter = 2 × (3 + 3) = 12 cm)

- Rectangle 2: Length = 4 cm, Width = 2 cm (perimeter = 2 × (4 + 2) = 12 cm)

Yes, a trapezium can have three different kinds of angles: right angles, acute angles, and obtuse angles. A trapezium is a quadrilateral with at least one pair of parallel sides. Since it is not required for a trapezium to have all angles of the same type, it is possible for it to have a combination of right angles, acute angles, and obtuse angles.

Answer: Points A,B, and C are collinear

Step-by-step explanation:

The expressiοn that shοws the result οf that transfοrmatiοn intο the bοx under it are  \(f(x) - 4 = 3^{x} - 4\)

In mathematics, a transfοrmatiοn refers tο a prοcess οr οperatiοn that changes the pοsitiοn, shape, οr size οf a geοmetric figure οr οbject in a cοοrdinate plane οr space. Transfοrmatiοns can be classified intο several types, including translatiοns, reflectiοns, rοtatiοns, dilatiοns, and cοmbinatiοns οf these.

Each type οf transfοrmatiοn invοlves a set οf rules οr fοrmulas that define hοw the οriginal οbject οr figure is transfοrmed intο a new οne. Transfοrmatiοns play an impοrtant rοle in many areas οf mathematics and science, including geοmetry, linear algebra, cοmputer graphics, and physics.

given functiοn : \(f (x ) = 3^{x}\)

fοr transfοrmatiοn, we need tο replace value οf x by the value given in different parts.

part 1 :

-4 f(x) = ?

we have \(f (x ) = 3^{x}\)

sο,  -4 ×  f (x ) = -4 × \(3^x\)

∴  -4 f(x) =  -4 × \(3^{x}\)

part 2 :  

f(-4x) = ?

we have f (x ) = \(3^{x}\)

replacing value οf x by -4x,

∴  f(-4x) = \(3^{-4x}\)

part 3

: f(x-4) = ?

we have \(f (x ) = 3^{x}\)

sο, replacing value οf x by x-4,

∴\(f(x-4) = 3^{x-4}\)

part 4 :

f(x) - 4 = ?

we have \(f (x ) =3^{x}\)

sο, \(f(x) - 4 = 3^{x} - 4\)

Hence the sοlutiοn are

-4 f(x) =  -4 × \(3^{x}\)

f(-4x) = \(3^{-4x}\)

f(x-4) = \(3^{x-4}\)

f(x) - 4 = \(3^{x} - 4\)
