Using the radius of the Ferris wheel and the angle between the two positions, the time spent on the ride when they're 28 meters above the ground is 12 minutes
How many minutes of the ride are spent higher than 28 meters above the ground?The radius of the Ferris wheel is 30 / 2 = 15 meters.
The highest point on the Ferris wheel is 15 + 4 = 19 meters above the ground.
The time spent higher than 28 meters is the time spent between the 12 o'clock and 8 o'clock positions.
The angle between these two positions is 180 degrees.
The time spent at each position is 10 minutes / 360 degrees * 180 degrees = 6 minutes.
Therefore, the total time spent higher than 28 meters is 6 minutes * 2 = 12 minutes.

3x+6≥24.
B.
3x+12≥24.
C.
3x+12≥18.
D.
3x+21≥24.
An inequality equivalent to 6x+12≥48 is 3x+6≥24.
What is inequality?
Inequality means not equal. Generally, if two values are not equal, we use the “not equal symbol (≠)”. But to compare the values, whether it is less than or greater than, different inequalities are used.
This is because dividing both sides of the original inequality by 6 results in 3x + 6 ≥ 24.
In option B, C and D, the inequality is not equivalent to the original inequality, as they have different values on one side of the inequality sign.
In option B: 3x+12≥24, the left side of the inequality is greater than the left side of the original inequality.
In option C: 3x+12≥18, the right side of the inequality is lesser than the right side of the original inequality.
In option D: 3x+21≥24, the left side of the inequality is greater than the left side of the original inequality and the right side of the inequality is greater than the right side of the original inequality.
Hence, An inequality equivalent to 6x+12≥48 is 3x+6≥24.

Moore's law states that the maximum number of transistors that can fit on a silicon chip doubles every two years. The function f(x)= 42(1.41) to the X power model the number of transistors, in millions, that can fit on a chip, where X is the number of years since 2000. Using this model, in what year can a chip hold 1 billion transistors?
We can say that a chip can hold 1 billion transistors in the year 2007.
To solve for the year when a chip can hold 1 billion transistors, we need to set the function f(x) equal to 1000 (since 1 billion is 1000 million).
So,\(42(1.41)^x = 1000\)
Divide both sides by 42:
\((1.41)^x = 23.81\)
Take the logarithm of both sides (with base 1.41):
x = log(23.81)
Using a calculator, we find that x is approximately 5.98.
Since X represents the number of years since 2000, we add 5.98 to 2000 to get the year when a chip can hold 1 billion transistors:
2000 + 5.98 = 2006.98
Rounding to the nearest year, we can say that a chip can hold 1 billion transistors in the year 2007.

An angle measure is 4 more than twice it’s complement. What would it’s supplement measure?
The measure οf the supplementary angle οf x = 61.33° is fοund tο be 118.67°.
What is an angle?An angle is a figure in plane geοmetry that is created by twο rays οr lines that have a shared endpοint. The twο rays are termed the sides οf an angle, and the cοmmοn terminatiοn is called the vertex. Angles are typically expressed as degrees. A "prοtractοr" is a crucial geοmetrical instrument that aids in measuring angles in degrees. Twο sets οf numbers οn a prοtractοr are οriented in οppοsitiοn tο οne anοther. On the οutside rim, οne set gοes frοm 0 tο 180 degrees, while οn the inner rim, the οther set gοes frοm 180 tο 0 degrees.
Let the angle be x.
Twο angles are cοmplementary when their sum is 90°.
Tοw angles are supplementary when their sum is 180°
If x is οne angle, then its cοmplementary angle is (90-x)°
Given x is 4 mοre than twice its cοmplement.
We can write the equatiοn as:
x = 4 + 2*(90-x)
Sοlving,
x = 4 + 180 - 2x

What is the slope of the equation y-3 = -4(x - 5)?
By answering the presented question, we may conclude that As a result, the slope of \(y_3\) = -4(x - 5) is -4.
what is slope?The slope of a line indicates how steep it is. The term "gradient overflow" refers to a mathematical equation for the gradient (the change in y divided by the change in x).
The slope is defined as the ratio of the vertical change (rise) between two places to the horizontal change (run). The slope-intercept form of an equation is used to express a straight line's equation, which is written as y = mx + b.
The y-intercept is found where the slope of the line is m, b is b, and (0, b). For example, the slope and y-intercept of the equation y = 3x - 7 (0, 7). The slope of the line is m. b is b at the y-intercept, and (0, b).
The above equation is in point-slope form: y - \(y_1\)= m(x - \(x_1\)), where (\(x_1\), \(y_1\)) is a point on the line and m is the slope.
We can see by comparing the provided equation to the point-slope form that \(x_{1} ,y_1\)) = (5, 3) and m = -4.
As a result, the slope of \(y_3\) = -4(x - 5) is -4.

The angle between the sides measuring 4 and 5 in the obtuse triangle is approximately 101.54 degrees.
To find the measure of the angle between the sides measuring 4 and 5 in an obtuse triangle with side lengths 4, 5, and 7, we can use the Law of Cosines. The Law of Cosines states that in a triangle with side lengths a, b, and c, and an angle opposite to side c, the following equation holds:
\(c^2 = a^2 + b^2 - 2ab*cos(C)\)
In this case, we have side lengths a = 4, b = 5, and c = 7. We want to find the angle C, which is opposite to side c. Substituting these values into the Law of Cosines, we get:
\(7^2 = 4^2 + 5^2\)- 2(4)(5)*cos(C)
49 = 16 + 25 - 40*cos(C)
49 = 41 - 40*cos(C)
40*cos(C) = 41 - 49
40*cos(C) = -8
cos(C) = -8/40
cos(C) = -0.2
To find the measure of angle C, we can take the inverse cosine (arccos) of -0.2:
C = arccos(-0.2)
Using a calculator, we find that C ≈ 101.54 degrees.
Therefore, the measure of the angle between the sides measuring 4 and 5 in the obtuse triangle is approximately 101.54 degrees.

20.25 square units are enclosed between the two curves.
How to find area?To find the area enclosed between the two curves, find their intersection points first.
Setting the equations equal to each other:
8x² - x³ + x = x² + 13x
Simplifying and rearranging:
x³ - 7x² - 12x = 0
Factoring out x:
x(x² - 7x - 12) = 0
Solving for x using the quadratic formula:
x = 0, x = 3, x = -4
The two curves intersect at x = 0, x = 3, and x = -4.
Next, determine which curve is on top of the other between these intersection points. We can do this by comparing their y-values for each x:
At x = -4, y = 128
At x = 0, y = 0
At x = 3, y = 27
So, the curve y = 8x² - x³ + x is on top of y = x² + 13x for x in the range -4 ≤ x ≤ 0, and y = x² + 13x is on top of y = 8x² - x³ + x for x in the range 0 ≤ x ≤ 3.
Now find the area between the curves using integration:
∫[from -4 to 0] [(8x² - x³ + x) - (x² + 13x)] dx + ∫[from 0 to 3] [(x² + 13x) - (8x² - x³ + x)] dx
Simplifying:
∫[from -4 to 0] (-x³ + 7x² - 12x) dx + ∫[from 0 to 3] (x³ - 7x² + 12x) dx
Integrating:
[-(1/4)x⁴ + (7/3)x³ - 6x²] from -4 to 0 + [(1/4)x⁴ - (7/3)x³ + 6x²] from 0 to 3
Simplifying:
(64/3) + (81/4) - (27/3) - (64/3) = 20.25
Therefore, the area enclosed between the two curves is 20.25 square units.

as we can see on the graph and the coordinate units,
AB = 4
BC = 7
=>
AC² = AB² + BC² = 4² + 7² = 16+49 = 65
AC = sqrt(65)
now, in every triangle there are certain ratios equal to each other.
a/sin(A) = b/sin(B) = c/sin(C)
a is here BC
b is here AC
c is here AB

ANSWER
$59.55
EXPLANATION
We have that Julio is paid 14% of his first $120 of sales and 19% of any sales more than $120.
He sold $345 worth of cookies last month.
To find the amount his gross paycheck will be, we have to partition the money he earned that month since he is paid in 2 parts.
We have to find out how much more than $120 he made:
$345 - $120 = $225
Now, we will find 14% of $120 and 19% of $225:
\(\begin{gathered} \frac{14}{100}\cdot\text{ 120 = \$}16.80 \\ \frac{19}{100}\cdot\text{ 225 = \$}42.75 \end{gathered}\)Now, we find the sum:
Gross Paycheck = $16.80 + $42.75
Gross Paycheck = $59.55
His gross paycheck that month will be $59.55

\(y=\frac{1}{6} \sqrt{(3x^{2}-1)^{2}} - \frac{1}{6} \sqrt{(3(-2)^{2}-1)^{2}} \)\)
In mathematics, an integral is a mathematical object that can be interpreted as an area or a generalization of area. Integrals, together with derivatives, are the two main tools used in calculus and are used to calculate areas, volumes, and their generalizations.
The integral \(y=\int_{-2}^{x} \sqrt{3 t^{4}-1} d t\) can be evaluated by first completing the square and then using the substitution method.
Completing the square gives us \(( 3 t^{4} -1 = (3t^{2} -1)^{2} \)\).
We can now make the substitution \(( u = 3 t^{2} -1 \)\)).
Differentiating, we get \(( du = 6t dt \)\)).
Therefore, the integral can be written as\(y=\int_{-2}^{x} \sqrt{(3t^{2}-1)^{2}} \frac{du}{6t} \)\).
Solving the integral, we get:
\(y = \frac{1}{6} \sqrt{(3t^{2}-1)^{2}} +C \)\)
