A sequence is a list of things in which repeats are permitted and order is important. The last term of the missing pattern is 57.

What is a sequence?

A sequence is a list of things in which repeats are permitted and order is important. It has members, just like a set. The length of the sequence is defined by the number of items.

In the given sequence, the difference between the first two-term is 4, while in the next two-term is 16(4²), Therefore, in the next two-term, the difference between the two terms will be equal to 64(4³).

Therefore, the last term will be,

Hence, the last term of the missing pattern is 57.

Using the volume of the room we know that the area of the floor is 139 m² respectively.

A cuboid is a six-sided solid known as a hexahedron in geometry. Quadrilaterals make up its faces.

Cuboid is short for "like a cube".

A cuboid is similar to a cube in that a cuboid can become a cube by varying the lengths of the edges or the angles between the faces.

A cuboid's volume is calculated by summing its length, breadth, and height.

So, let the values be:

Breadth = b

Length = 2b

Height = 2b/3

The volume of the cuboid:

V=whl

Insert values:
V=whl

972=b*2b*2b/3

972*3=b*2b*2b

2,916=b*2b*2b

2,916=5b³

b³=2916/5

b³=583.2

b=³√583.2

b=8.35 m

Now, l = 2b ⇒ 2(8.35) = 16.7 m

Now, the area of the floor is: l * b

= 16.7 * 8.35

= 139.445 m²

Rounding off: 139 m²

Therefore, using the volume of the room we know that the area of the floor is 139 m² respectively.

The statement which is true about the minimum values of the two quadratic functions presented in the question is f(x) and g(x) have the same minimum value. Therefore, the correct option is option C.

When  [tex]tan(\theta) = 1[/tex] , the value of  [tex]sin(\theta)[/tex] in quadrant III is [tex]\frac{-1}{\sqrt{2} }[/tex]. Therefore the correct option is option B.

First picture

Finding the vertex of each function, to determine the minimum values of functions. The vertex of a quadratic function in the form [tex]f(x) = ax^{2} +bx + c[/tex] can be find by the coordinates [tex](\frac{-b}{\ 2a} , f(\frac{-b}{\ 2a} ))[/tex].

For function [tex]f(x) = x^{2} +4x - 4[/tex], a = 1, b = 4. Substituting these values in vertex formula,

[tex]x = \frac{-b}{\ 2a} = \frac{-4}{\ (2\ *\ 1)} = -2[/tex]

Finding the value of f(-2):

[tex]f(-2) = (-2)^{2} + 4(-2) - 4[/tex]

= 4 - 8 - 4

= -8

So the vertex of f(x) is (-2, -8), and the minimum value is -8.

For function g(x)

From the values, the minimum value of g(x) is -8, which occurs when x = 0.

Comparing the minimum values of f(x) and g(x),

Minimum value of f(x) is -8

Minimum value of g(x) is -8

Therefore, the correct answer is: C. f(x) and g(x) have the same minimum value.

Second picture

In Quadrant III, x-coordinate and y-coordinate both are negative.

[tex]tan(\theta) = \frac{sin(\theta)}{cos(\theta)} = 1[/tex]

Since, [tex]cos(\theta)[/tex] is negative and [tex]tan(\theta) = 1[/tex], using the Pythagorean identity to find [tex]cos(\theta)[/tex],

[tex]cos^2(\theta) = \frac{1 }{(1 + tan^2(\theta))}[/tex]

[tex]cos^2(\theta) = \frac{1}{(1 + 1)}[/tex]

[tex]cos^2(\theta) = \frac{1}{2}[/tex]

[tex]cos(\theta) = \sqrt{\frac{1}{2} }[/tex]

[tex]cos(theta) = -\frac{\ 1}{\sqrt{2} }[/tex]

⇒ [tex]sin(\theta) = tan(\theta) * cos(\theta)[/tex]

[tex]sin(\theta) = 1 * (-\frac{1}{\sqrt{2} } )[/tex]

[tex]sin(\theta) = -\frac{\ 1}{\sqrt{2} }[/tex]

Therefore, in Quadrant III, [tex]sin(\theta) = -\frac{\ 1}{\sqrt{2} }[/tex]

Step-by-step explanation:

The overall free throw success rate in the entire game is 25%

A rate is a ratio that compares two different quantities which have different units.

Success rate of free = number of free throw made ÷ total number of free throws × 100

In the first half,

represent the total free throw by x

40 = 2/x × 100

40x = 200

x = 200/20

x = 5

In the second half;

20 = 3/x × 100

20x = 300

x = 300/20

x = 15

Therefore the total success rate of free throw = total number of free throw made ÷ total number of free throws × 100

= (3+2)/(15+5)

Using both hoses at the same time, it would take 10 minutes to fill up the kiddie pool. The correct option is B).

Let's call the time it takes to fill up the pool using the back hose alone "B". From the problem, we know that B = 30 minutes. We also know that the front hose fills the pool in half the time of the back hose, so the time it takes to fill up the pool using the front hose alone is 1/2 B = 15 minutes.

Now let's use the formula for "combined work" to find out how long it will take to fill the pool using both hoses at the same time. The formula is

Combined time = (time for hose A * time for hose B) / (time for hose A + time for hose B)

Let's let "A" represent the time it takes to fill up the pool using both hoses at the same time. We know that the combined time is the time it takes to fill up the pool, so A is what we're looking for.

Using the formula, we get

A = (30 * 15) / (30 + 15)

A = 10 minutes

Therefore, it will take 10 minutes to fill up the pool using both hoses at the same time. The correct answer is B.

Given that;

The EOC exams are normally distributed with a mean of 702.19 and a standard deviation of 35.81. A score of 700 is needed to earn 3 points.

Now, We can formulate;

a) The graph shows the mean and the values at ±1, ±2, and ±3 standard deviations from the mean. Each mark differs from the one below by the value of the standard deviation, 36.18. The central mark is the mean, 704.39.

e) EOC would be the easiest. The required score has the lowest z-value, so the applicant only needs to do better than a smaller number of peers.

Actually, the answer to this depends on why the thresholds vary. If we assume that the threshold on each test is set appropriate to the desired knowledge and ability, the test-taker would find his knowledge and ability allows him to do better on the ACT than on the other tests.

Using a trigonometric relation we can see that the value of the missing side is x = 3.9

We can use the trigonometric relation:

cos(75°) = adjacent cathetus/hypotenuse

Where the adjacent cathetus is x, and the hypotenuse measures 15 units, then we can replace these values to get.

cos(75°) =x/15

Solving this for x we get.

15*cos(75°) =x

3.9 = x

Answer:

The answer is: y ≤ (2/3)x - 1/2

Step-by-step explanation:

Add 2y to both sides of the inequality:

2/3x ≥ 1 + 2y

Subtract 1 from both sides of the inequality:

2/3x - 1 ≥ 2y

Divide both sides by 2 to isolate y:

y ≤ 1/2(2/3x - 1)

This gives you the inequality in slope-intercept form, y ≤ (2/3)x - 1/2, where the slope is 2/3 and the y-intercept is -1/2.

To graph the boundary line, plot the y-intercept at (0, -1/2) and then use the slope to find another point. For example, if you move up 2 units and to the right 3 units from the y-intercept, you'll arrive at the point (3, 1/2). Connect these two points with a straight line to graph the boundary line.

Finally, to shade the region of the coordinate plane that satisfies the inequality, test any point above or below the boundary line to see if it's a solution to the inequality. If the point satisfies the inequality, shade the region that it's in. If it doesn't, shade the opposite region.

Answer:

  1428000

Step-by-step explanation:

You want the principal that would result in interest of 11900 at a rate of 6% for a period of 50 days.

Ordinary interest is calculated on the basis of 360 days per year. The fraction of a year represented by 50 days is 50/360, so the interest formula tells us ...

  I = Prt . . . . . . . where P is the principal at rate r for t years

  11900 = P·0.06·(50/360)

  P = 11900/(0.06·50/360) = 1428000

The measurements which is best estimate is given as 6m, 100grams, 2L.

Measurement is the process of quantifying a physical property of an object or phenomenon, typically by comparing it to a standard unit of measurement. This allows for precise and objective description and comparison of different quantities.

An estimate is an approximate calculation or judgment of the value, amount, size, or cost of something, based on available information and assumptions. It is often used when precise measurements or exact values are not available or practical. Estimates can be useful in planning, budgeting, and decision-making, but they should be used with caution and updated as more accurate information becomes available.
