Answer:

The equation that represents the relationship between 'y' the total points, and 'x' the number of movies is option A;

A y = 3·x

Step-by-step explanation:

The information required in the question is an equation that represents the the relationship between the number of movie attended and the total number of points Marcy has given that she earns a fixed amount of points for attending each movie

The number of points she will earn for attending each movie = 3 points

The total number of points she will earn 'y' when she attends 'x' number of movies is given as follows;

y = 3 + 3 + 3 + ... + 3, 'x' number of times, and we can write

[tex]y = \sum\limits_{i =1}^x 3 = 3 \times x[/tex]

Therefore the equation that represents the relationship between 'y' the total points, and 'x' the number of movies is y = 3·x.

Answer:

A - y = 1200(1+.05)^30

Step-by-step explanation:

In this case, you need to calculate the future value and the formula to calculate that is:

FV=PV*(1+r)^n

FV=future value

PV=present value

r=rate

n=number of periods of time

The present value would be the price of the ring which is $1200. The rate is 5% per year and the number of periods of time is 30 years since you need to find the ring's worth in 30 years. Now, you can replace the values on the formula:

FV=1200*(1+0.05)^30

According to this, the answer is that the equation to calculate how much will it be worth in 30 years is: y = 1200(1+.05)^30.

Answer:

the right answer is:

Step-by-step explanation:

You take the equations that the exercise give you:

Now you clear the "y" variable in any equation you want, in this case, I'm gonna use the second equation:

   3. y =  x - a

And now, you'll replace this third equation in the equation you didn't take (the first in this case).

Add the x variables:

That's the answer of the exercise, but you can represent this in this form:

By this reason, the right answer is [tex]x = 2+ \frac{1}{2} a[/tex].

The value of x for which the trinomial 2x^2−x+55 equal to the square of binomial x+5 is 5 and 6

Given the equation 2x^2−x+55, if the expression is equal to the square of binomial x + 5, then;

2x^2−x+55 = (x+5)^2

2x^2−x+55 = x^2 + 10x + 25

Collect the like terms;

2x^2-x^2-x-10x+55-25 = 0

x^2 - 11x + 30 = 0

Factorize the result

x^2 - 6x - 5x + 30 =0

x(x-6)-5(x-6) = 0

x-5 = 0 and x - 6  = 0

x = 5 and 6

Hence the value of x for which the trinomial 2x^2−x+55 equal to the square of binomial x+5 is 5 and 6

Answer:

Median --> 357.5

Q1 --> 298

Q3 --> 422

IQR > 124

Step-by-step explanation:

3 daily attendance at the water park: 346, 250, 433, 369, 422,298

Find the median, Q1, Q3,and IQR

Step 1

We rearrange the given data set

250, 298, 346, 369, 422, 433

a) The Median

The formula to find the Median

= 1/2( n + 1)th term

Where n = Number of terms = 6

Median = 1/2(6 + 1)th

= 1/2(7)th term

= 3.5th term

The 3.5th term = The number between the 3rd and 4th term

3rd term = 346

4th term = 369

Hence,Median = 346 + 369/2

= 357.5

2) Q1 = First Quartile

= 1/4(n + 1)the

= 1/4( n + 1)th term

Where n = Number of terms = 6

Median = 1/4(6 + 1)th

= 1/4(7)th term

= 1.75th term

The 1.75th term = 2nd term

= 298

Q1 = 298

3) 3/4( n + 1)th term

Where n = Number of terms = 6

Median = 3/4(6 + 1)th

= 3/4(7)th term = 21/4th term

= 5.25th term

The 5.25th term = 6th term

Q3 = 422

4) Interquartile Range = Q3 - Q1

= 422 - 398

= 124

Step-by-step explanation:

3 times 3

The area of the triangle, Δ AMN is 8 cm², so the area of the triangle, ΔMCN is 24 cm².

A triangle is one of the most basic geometric figures with 3 sides, 3 angles, and 3 vertices.

The area of a triangle is half of the product of the base and height.

Given that

ABCD is square and M and N are mid-points of lines AB and AD respectively.

Area of triangle, ΔAMN = 8 cm²

[tex]\dfrac{1}{2} \times AN \times AM = 8\\AN \times AM = 8 \times 2\\AN \times AM = 16[/tex] ...(i)

Since ABCD is square, therefore AB = AD.

Also, as M and N are mid-points of lines AB and AD, so

AN = AM.

Substitute AN = AM in equation (i),

[tex]AN \times AN = 16\\AN^2 = 16\\AN = \sqrt{16}\\AN = 4\ cm[/tex]

So,

AD = 2 × AN

     = 2 × 4

     = 8 cm

As ABCD is square,

AB = BC = CD = AD = 8 cm.

Area of the square ABCD = 8² = 64.

Since CD = BC, ND = MB, ∠D = ∠B.

Therefore by SAS property of similarity,

ΔCDN ≅ ΔCBM

Area of the triangle, ΔCDN = Area of the triangle, ΔCBM.

                                              [tex]= \dfrac{1}{2} \times CB \times BM\\= \dfrac{1}{2} \times 8 \times 4\\\\= 16\ cm^2[/tex]

Area of the triangle, ΔCMN = Area of ABCD - Area of ΔAMN - Area of ΔCDN - Area of ΔCBM

Area of the triangle, ΔCMN = 64 - 8 - 16 - 16

                                              = 24 cm²

Therefore, the area of ΔCMN  is 24 cm².

Answer:

The use different equations but both equal 3

Step-by-step explanation:

Step-by-step explanation:

sin^2(x)= 3 cos^2(x)

Subtract sin^2(x) on both sides

0=3cos^2(x)-sin^2(x)

By Pythagorean Identity sin^2(x)+cos^2(x)=1, we can replace cos^2(x) with 1-sin^2(x)

0=3(1-sin^2(x))-sin^2(x)

Distribute

0=3-3sin^2(x)-sin^2(x)

Combine like terms

0=3-4sin^2(x)

Add 4sin^2(x) on both sides

4sin^2(x)=3

Divide both sides by 4

sin^2(x)=3/4

Take the square root of both sides

sin(x)=+ or - sqrt(3/4)

sin(x)=+ or - sqrt(3)/sqrt(4)

sin(x)=+ or - sqrt(3)/2

This happens on the unit circle at

x is 120 degrees or (120+360n) degrees in the second quadrant. I didn't know if you were just looking for solutions in the first nonnegative cycle of the unit circle or not.
