I need help with number 5 please I don’t really get this:):);):):): it probability

Answer:

Sadly, you are wrong. The right answer is the 3rd one.

Step-by-step explanation:

Basically, a constant term basically means a term that contains only a number, and all the other ones have a variable other than 8, which means it has to be 8. Second, the exponent of the 3rd term, which is 3y, is 1 since the exponent is what you would call the small number at the top right of a number (I guess?). Basically, if there is no exponent, the exponent is 1.

The new water bill after 5% increase is $126.

The ratio that may be stated as a fraction of 100 is called as a percentage in mathematics. To compute a percentage of a number, divide it by its whole and then multiply it by 100. The percentage therefore refers to a component per hundred. Per 100 is what the term percent signifies. The letter "%" stands for it.

Given bill of water =$120

Increment in percentage=5%

New water bill= 120+120×5/100

=$126

Hence, The new water bill after 5% increase is $126.

% increase = Increase in bill ÷ Old bill × 100.

5%=Increase in bill/120×100

Increase=5×120/100

=6

New bill=Old bill+ increase=120+6=126

hence, the new water bill after 5% increase is $126.

Answer: Hmm this question was very hard.

Step-by-step explanation:

Amplitude is the maximum displacement of a function on a graph.

Amplitude is the maximum displacement of a function on a graph. It refers to the maximum height or distance from the baseline of a wave or oscillation.

It is often used in physics and engineering to describe the strength or size of a signal, vibration, or wave. In simple terms, it can be thought of as the "peak-to-peak" distance of a waveform, or the height of the waveform above and below the baseline.

But the minimum displacement of a function on a graph would typically be referred to as the minimum value or the "valley" of the function.

We have verified the given identity: 6 cos(x + y)cos(x − y) = 6 cos^2(x) − 6 sin^2(y).

To verify the given identity, let's simplify the expression step by step:

Starting with the left side of the equation:

6 cos(x + y)cos(x − y)

Using the cosine of the sum and difference of angles formula:

6 [cos(x)cos(y) − sin(x)sin(y)][cos(x)cos(y) + sin(x)sin(y)]

Expanding the expression:

6 [cos(x)^2cos(y)^2 − sin(x)^2sin(y)^2]

Using the trigonometric identity cos^2(x) = 1 - sin^2(x):

6 [(1 - sin^2(x))(1 - sin^2(y)) − sin^2(x)sin^2(y)]

Expanding further:

6 [1 - sin^2(x) - sin^2(y) + sin^2(x)sin^2(y) - sin^2(x)sin^2(y)]

Combining like terms:

6 [1 - sin^2(x) - sin^2(y) + 2sin^2(x)sin^2(y)]

Now, let's simplify the right side of the equation:

6 cos^2(x) - 6 sin^2(y)

Using the trigonometric identity cos^2(x) = 1 - sin^2(x):

6 (1 - sin^2(x)) - 6 sin^2(y)

Simplifying further:

6 - 6 sin^2(x) - 6 sin^2(y)

Comparing the simplified expressions on both sides, we can see that they are equal:

6 [1 - sin^2(x) - sin^2(y) + 2sin^2(x)sin^2(y)] = 6 - 6 sin^2(x) - 6 sin^2(y)

The acceleration of the car is 8 m/s^2.

The figure shown in the question is the distance-time graph of a muscle car accelerating from a standstill. The table lists the coordinates of points on the graph.The following observations can be made from the graph and the table: The car is at rest at time t=0 and at distance x=0. It then starts accelerating, and its speed increases uniformly with time. The slope of the distance-time graph is the velocity of the car.

Since the velocity is increasing uniformly, the slope of the graph is a straight line with a positive slope. The area under the graph between two points gives the displacement of the car during that time interval. The displacement can be calculated as the product of the average velocity and the time interval. Using the coordinates in the table, we can calculate the average velocities for each time interval and the displacement during that interval.

(a) The average velocity of the car between t=0 and t=2 is equal to the slope of the graph between the two points (0,0) and (2,32). This can be calculated as the difference in distance divided by the difference in time:Average velocity = (32 - 0) / (2 - 0) = 16 m/sThe displacement during this time interval is given by the area under the graph between the two points:Displacement = (1/2) x 32 x 2 = 32 m

(b) The acceleration of the car is given by the slope of the velocity-time graph. Since the velocity is increasing uniformly with time, the velocity-time graph is also a straight line with a positive slope. The slope of the velocity-time graph is equal to the acceleration. We can calculate the slope of the velocity-time graph between two points using the coordinates in the table. For example, the slope between t=0 and t=2 is given by the difference in velocity divided by the difference in time:Slope = (16 - 0) / (2 - 0) = 8 m/s^2

Cy + -5 = -3d + 6y

Reorder the terms:

-5 + yC = -3d + 6y

Solving

-5 + yC = -3d + 6y

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Add '-6y' to each side of the equation.

-5 + -6y + yC = -3d + 6y + -6y

Combine like terms: 6y + -6y = 0

-5 + -6y + yC = -3d + 0

-5 + -6y + yC = -3d

Add '5' to each side of the equation.

-5 + -6y + 5 + yC = 5 + -3d

Reorder the terms:

-5 + 5 + -6y + yC = 5 + -3d

Combine like terms: -5 + 5 = 0

0 + -6y + yC = 5 + -3d

-6y + yC = 5 + -3d

Reorder the terms:

-5 + 3d + -6y + yC = 5 + -3d + -5 + 3d

Reorder the terms:

-5 + 3d + -6y + yC = 5 + -5 + -3d + 3d

Combine like terms: 5 + -5 = 0

-5 + 3d + -6y + yC = 0 + -3d + 3d

-5 + 3d + -6y + yC = -3d + 3d

Combine like terms: -3d + 3d = 0

Modified Euler's method is a numerical method used to solve ordinary differential equations (ODEs). It is a variation of Euler's method that is more accurate than the original, but still relatively simple to implement. It works by taking a single iteration of the Euler method, then using the midpoint between the current and previous points to calculate the next point in the sequence. This is done in order to reduce the error.

Solution

We have, y(0) = 0

dy/dt = 1 – y

h = 0.1

Using modified Euler's method,

y(0.1) = y(0) + (1/2) h (f(t0, y0) + f(t0 + h, y0 + hf(t0, y0)))

= 0 + (1/2) (0.1) [(1 - 0) + (1 - 0 + 0.1)]

= 0.05

Similarly,

y(0.2) = 0.1 + (1/2) (0.1) [(1 - 0.05) + (1 - 0.1 + 0.1)]

= 0.0975

The algebraic expression for √(4+x)(10-x), which is 121.

To find the value of √(4+x)(10-x) algebraically, we start by simplifying the given equation:

√(4+x) + √(10-x) = 6

To eliminate the square roots, we can square both sides of the equation:

(√(4+x) + √(10-x)\()^2 = 6^2\)

Expanding the left side using the binomial formula, we get:

(4+x) + 2√[(4+x)(10-x)] + (10-x) = 36

Simplifying further:

14 + 2√[(4+x)(10-x)] = 36

Subtracting 14 from both sides:

2√[(4+x)(10-x)] = 22

Dividing both sides by 2:

√[(4+x)(10-x)] = 11

Now we can square both sides again to get rid of the square root:

[(4+x)(10-x)] = \(11^2\)

Simplifying further:

The value of side length x in diagram a) is 4.3mm and side length x in diagram b) is 309.7 m.

The figures in the image are right triangles.

A)

angle D = 17 degree

Adjacent to angle D = 14 mm

Opposite to angle D = x

To solve for the missing side length x, we use the trigonometric ratio.

Note that: tangent = opposite / adjacent

Hence:

tan( 17 ) = x/14

x = tan( 17 ) × 14

x = 4.3mm

B)

angle Z = 82 degree

Adjacent to angle Z = 43.1 m

Hypotenuse = x

Using trigonometric ratio,

cosine = adjacent / hypotenuse

cos( 82 ) = 43.1 / x

x = 43.1 / cos( 82 )

x = 309.7 m
