What is the slope of the linear equation 2y 3x − 1?

The next three number is 1/125, 1/625, 1/3125.

What is pattern?

A recurring arrangement of numbers, forms, colours, and other elements constitutes a pattern in mathematics. The Pattern can be connected to any kind of occasion or thing. When a group of numbers are arranged in a particular way, the arrangement is referred to as a pattern. Patterns can also occasionally be referred to as a series.

Given pattern is 25, 5, 1, 1/5,  1/25.

Assume first term is a₁ = 25

The second term is a₂ = 5

The third term is a₃ = 1

The fourth term is a₄ = 1/5

The fifth term is a₅ = 1/25

The ratio of each consecutive term is

a₂/a₁= a₃/a₂ = a₄/a₃ = a₅/a₄ = 1/5.

The 6th term is a₆ = (1/25)× (1/5) = 1/125

The 7th term is a₇ = (1/125) × (1/5) = 1/625

The 8th term is a₈ = (1/625) × (1/5) = 1/3125

During the first 10 seconds, in the intervals (0, 2) and (6, 10) the acceleration is increasing.

The acceleration is: y = 7*sin( x*pi/4).

Sin(θ) increases between -pi/2 and pi/2

Sin(θ) decreases between pi/2 and (3/2)*pi.

And so on.

Here we have:

θ = x*(pi/2)

When x = 0, θ = 0.

And sin(θ) is increasing in θ = 0.

Then we must choose one of the options that start with x = 0.

now it will stop increasing when:

θ = pi/2 = x*(pi/4)

x = 2.

So the acceleration is increasing in the segment (0,2)

And it will start increasing again when:

θ = (3/2)*pi = x*(pi/4)

(3/2)*pi*(4/pi) = 6 = x.

So at x= 6 the acceleration starts increasing again, and the acceleration is only defined until x = 10, then

the correct option is: (0, 2) and (6, 10)

Thus, during the first 10 seconds, in the intervals (0, 2) and (6, 10) the acceleration is increasing.

Answer:

$25000

Step-by-step explanation:

100% - 34% = 66%

We know that

66% = $16,500

We have to find 1%

16500 divided by 66 = $250

Then we have to find the 34%

250 times 34 = $8500

Then we add both numbers to find their previous year's revenue

$16500 + $8500 = $25000

So, their previous year's revenue is $25000

The solution to the evaluation of the expression x(y² - z) x = 6, y = 4 and z = 1 is 90

x(y² - z)

substitute the value of x, y and z

= 6(4² - 1)

Applying PEMDAS:

Answer:

k = 48 , y = 48x

Step-by-step explanation:

given y varies directly as x then the equation relating them is

y = kx ← k is the constant of variation

to find k use the condition y = 12 when x = [tex]\frac{1}{4}[/tex] , then

12 = [tex]\frac{1}{4}[/tex] k ( multiply both sides by 4 to clear the fraction )

48 = k

constant of variation is then k = 48 , so

Answer:

To solve this problem, we can use the formula for the area of a triangle, which is A=1/2bh, where b is the base and h is the height. In this problem, we are given that the area of the triangle is 128 square centimeters, so we can set up the following equation:

A = 1/2bh

128 = 1/2bh

We are also given that the height of the triangle is 8 centimeters greater than three times the base, so we can set up the following equation:

h = 3b + 8

We can substitute the second equation into the first equation to get the following:

128 = 1/2bh

128 = 1/2(3b + 8)b

128 = 3/2b^2 + 4b

We can then use the quadratic formula to solve for b, the base of the triangle:

b = (-4 +/- sqrt(4^2 - 4(3/2)(128)))/(2(3/2))

b = (-4 +/- sqrt(64 - 192))/3

b = (-4 +/- sqrt(-128))/3

Since the square root of a negative number is not a real number, we know that there is no solution to this equation, which means that the given information is not sufficient to determine the base of the triangle.

Therefore, the correct answer is that the base of the triangle cannot be determined from the information given.

To solve this problem, we can use the formula for the area of a triangle, which is A=1/2bh, where b is the base and h is the height. In this problem, we are given that the area of the triangle is 128 square centimeters, so we can set up the following equation:

The correct Inequality that shows the above situation is 55 + 9h ≥ 199, the error in the given expression is taking less than or equal to.

Inequality simply means that two things aren't equal. One of the items might be lower too, greater than, or equivalent to the others.

Mathematical expressions with inequalities are those in which the two sides are not equal.  

the signs we use in Inequalities are

 ≠ means not equal to

< means less than  

> means greater than  

≤ means less than or equal to

≥ means greater than or equal to                  

Here we have

The student already saved $ 55

She earns $ 9 per hour

The money that she needs to buy the bicycle is at least $ 199

Let's assume that she worked for h hours to earn at least $ 199

The amount that she earned after h hours = 9h

As we know she already saved $ 55

Finally the amount that she had = 55 + 9h

She wants at least $ 199 but not less than that, so the amount 55 + 9h must be greater than $ 199

=> 55 + 9h ≥ 199  

The expression that the student used is 55 + 9h ≤ 199, here error is taking less than or equal to.

The percent error in zookeeper's prediction on baby elephant's weight is 13.79%.

What is percentage error?

Percentage error is the difference between the estimated value and the actual value compared to the actual value, expressed as a percentage. So the percent error is the relative error multiplied by 100.

Uses of percentage error:

The main purpose of calculating percent error is to analyze how close the measured value is to the actual value. This is part of a comprehensive error analysis.

Solution:

Percent error = (Actual weight - Predicted weight/Predicted weight)x100

Percent error = (264 - 232/232) x 100

Percent error = ( 32/232) x 100

The function f(x) = x³ - 7x + 1 for the given f''(x) = 6x, f'(-3) = 20 and f(-3) = -5. By using the antiderivative formula, the required function is evaluated.

The antiderivative formula for indefinite integrals is

[tex]\int f'(x)dx = f(x) + c[/tex]

or we can also write this as

[tex]\int f^n(x)dx = f^{n-1} + c[/tex]

It is given that,

f''(x) = 6x, f'(-3) = 20, f(-3) = -5

Then, by the antiderivative formula, we can write

[tex]\int f''(x)dx = f'(x) + c[/tex] ...(1)

On substituting, we get

[tex]\int f''(x)dx = \int 6x dx = 6\int xdx[/tex]

Since we have the formula for the indefinite integral, [tex]\int x^n dx = \frac{x^{n+1}}{n+1}+c[/tex], we get

[tex]\int f''(x)dx = 6(\frac{x^{1+1}}{1+1})+c[/tex]

⇒ [tex]\int f''(x)dx = 6(\frac{x^2}{2})+c=3x^2+c[/tex]

So, from (1), we get f'(x) = 3x² + c

But we have f'(-3) = 20. So, on substituting x = -3 in the above function f'(x), we get

f'(x) = 3x² + c

⇒ f'(-3) = 3(-3)² + c

⇒ 20 = 3(9) + c

⇒ 20 - 27 = c

∴ c = -7

So, the second derivative function is f'(x) = 3x² - 7.

From the antiderivative expression, we can write

[tex]\int f'(x)dx = f(x) + c[/tex] ...(2)

On substituting f'(x) in the above integral we get

[tex]\int f'(x) dx = \int (3x^2 +-7)dx[/tex]

⇒ [tex]\int f'(x)dx = 3\int x^2dx -7\int dx + c[/tex]

⇒ [tex]\int f'(x) dx = 3(\frac{x^3}{3})-7x+c[/tex]

⇒ [tex]\int f'(x) dx = x^3 - 7x + c[/tex]

From (2), we can write

f(x) = x³ - 7x + c

But we have f(-3) = -5;

Then,

f(-3) = (-3)^3 - 7(-3) + c

⇒ -5 = -27 + 21 + c

⇒ -5 = -6 + c

∴ c = -5 + 6 = 1

Thus, the function f(x) = x³ - 7x + 1.
