Answer:

d. y = (x - 1)(x-3)²(x + 2)²

Step-by-step explanation:

When there is a local max or local min on the x-intercept, then the function on the x-intercept is raised to an even power.

At x=3 and x=-2, the function goes up then down, or down then up.

If the function goes through an x-intercept when there is no local max or local min on the x-intercept, then the function on the x-intercept is raised to an odd power.

At x=1, the function goes through the x-intercept.

Hence, d is the answer.

The critical points for the inequality (2x+5/x+2>_ x-1/x-2), are x = -2 and x = 2. Option A

Generally, To find the critical points for the inequality, you need to set the expression on the left side of the inequality equal to zero and solve for x. This will give you the values of x where the inequality changes direction.

In this case, the inequality is:

2x + 5/(x + 2) > 0

To find the critical points, you can set the expression on the left side equal to zero and solve for x:

0 = 2x + 5/(x + 2)

0 = 2x + 5 - 5/(x + 2)

0 = 2x - 5 + 5/(x + 2)

0 = 2x - 5 + 5(x + 2)/(x + 2)

0 = 2x - 5 + 5x + 10

0 = 7x - 15

x = -2, x = 2

Therefore, the critical points for the inequality are x = -2 and x = 2.

It is not correct to say that the critical points are x = -6 and x = 2, x = -4 and x = 2, or x = 2. These values do not correspond to any points where the inequality changes direction.

By setting up the equation and solving we get the total amount of money was 1800.

A ratio is a way of comparing two or more quantities. It is expressed as a fraction or a decimal, and it represents the relative sizes of the quantities being compared.

An equation is a mathematical statement that shows the equality of two expressions. An equation typically consists of two expressions separated by an equals sign (=), and it states that the expressions are equal in value.

we can set up the following equation:

(2700 / X) = (3 / 4)

We can solve this equation for X by multiplying both sides by X:

2700 = (3 / 4) * X

2700 = (3 / 4) * X

The assumption of normality is important for valid results. If the residuals do not follow a normal distribution, then confidence intervals may not be accurate and should not be trusted.

The assumption of normality is a key element of statistical analysis. It suggests that a dataset follows a normal bell-shaped curve, which is important for reliable results. If the residuals of a dataset do not follow a normal distribution, then the assumptions of statistical techniques such as confidence intervals, least-squares formulas, and sample randomness, may be unreliable. This means that the results of any statistical analysis will be affected and not be as accurate as they could be. In this case, confidence intervals may be particularly unreliable since they rely on the assumption that the data is normally distributed. Therefore, if the residuals do not follow a normal distribution, it is important to investigate further to ensure the accuracy of the results.

example;

The mean of the data is 8.3 and the standard deviation is 4.2.

We can calculate the z-score for any given value by subtracting the mean from the value and then dividing by the standard deviation.

if the value is 16, then the z-score would be:

A square's area an is growing at a rate of 6 cm2 each minute. The side length of the square is increasing at a rate of 2.45 cm/min.

The side length of a square is related to the area of the square by the equation side length = square root of (area). That means, if the area is increasing, the side length of the square is also increasing. To calculate the rate at which the side length is changing, we can take the derivative of the equation side length = square root of (area) with respect to time. This gives us a rate of change of 2.45 cm/min. This means that for every minute the area increases by 6 cm2, the side length of the square will increase by 2.45 cm.

Rate of change = d(side length) / dt

= (1/2) * (d(area) / dt) / (square root of (area))

= (1/2) * (6 cm2/min) / (square root of (area))

= 2.45 cm/min

Considering the expression of a line, the equation of the line that passes through the pair of points (−4, −1) and (5, 7) is y=8/9x + 23/9.

A linear equation o line can be expressed in the form y = mx + b

where

Knowing two points (x₁, y₁) and (x₂, y₂) of a line, the slope m of the line can be calculated as:

m= (y₂ - y₁)÷ (x₂ - x₁)

Substituting the value of the slope m and the value of one of the points in the expression y = mx + b, the value of the ordinate to the origin b can be obtained.

Being (x₁, y₁)= (-4, -1) and (x₂, y₂)= (5, 7), the slope m can be calculated as:

m= (7 - (-1))÷ (5 - (-4))

Solving:

m= (7 +1)÷ (5 + 4)

m= 8÷ 9

m= 8/9

Considering point 2 and the slope m, you obtain:

7= 8/9×5 + b

The time taken by Bert to travel 50 miles distance with constant speed 30 miles per hour is an hour 40 minutes. So, right answer is option (b).

Speed is defined as the rate at which a particular object able to move or operate. It is a ratio of amount of distance to the time. Speed of object may be fast , slow or constant. The constant speed means there is no increase or decrease in speed during rides.

We have,bert's constant speed=30 miles/hour .

We have to calculate the time taken by Bert to travel 50 miles, i.e distance = 50 miles . Let "t hours " be time taken by Bert to travel 50 miles.

Speed= distance/time

=> time = distance/speed

=> t = 50 miles /30 miles/1 hour

=> t = 5/3 hours

Conversion of hours into minutes :

one hour = 60 minutes

5/3 hour =( 5/3 )× 60 minutes

=> 5/3 hour = 100 minutes = 60 minutes + 40 minutes= 1 hour 40 minutes

A circle above 3 going right

The area of the region enclosed by one loop of the curve r = sin(10θ) is π/40.

We have to find the area of the region enclosed by one loop of the curve.

The given curve is:

r = sin(10θ)

Consider the region r = sin(10θ)

The area of region bounded by the curve r = f(θ) in the sector a ≤ θ ≤ b is

A = [tex]\int^{b}_{a}\frac{1}{2}r^2d\theta[/tex]

Now to find the area of the region enclosed by one loop of the curve, we have to find the limit by setting r=0.

sin(10θ) = 0

sin(10θ) = sin0   or    sin(10θ) = sinπ

So θ = 0             or      θ = π/10

Hence, the limit of θ is 0 ≤ θ ≤ π/10.

Now the area of the required region is

A = [tex]\int^{\pi/10}_{0}\frac{1}{2}(\sin10\theta)^2d\theta[/tex]

A = [tex]\frac{1}{2}\int^{\pi/10}_{0}\sin^{2}10\theta d\theta[/tex]

A = [tex]\frac{1}{2}\int^{\pi/10}_{0}\frac{(1-\cos20\theta)}{2}d\theta[/tex]

A = [tex]\frac{1}{4}\int^{\pi/10}_{0}(1-\cos20\theta)d\theta[/tex]

A = [tex]\frac{1}{4}\left[(\theta-\frac{1}{20}\sin20\theta)\right]^{\pi/10}_{0}[/tex]

A = [tex]\frac{1}{4}\left[(\frac{\pi}{10}-\frac{1}{20}\sin20\frac{\pi}{10})-(0-\frac{1}{20}\sin20\cdot0)\right][/tex]

A = [tex]\frac{1}{4}\left[(\frac{\pi}{10}-\frac{1}{20}\sin2\pi)-(0-\sin0)\right][/tex]

A = 1/4[(π/10-0)-(0-0)]

A = 1/4(π/10)

A = π/40

Hence, the area of the region enclosed by one loop of the curve r = sin(10θ) is π/40.

To determine the distance from the ship's point of departure, we must first break down the distance traveled into x and y components. Initially, the ship traveled 35 miles due east, which can be represented as 35 miles on the x-axis. When the ship adjusted its course 40 degrees northward, it traveled 45 miles in that direction. This can be represented as 45 miles in the y direction, forming a triangle with the origin (point of departure). Using the Pythagorean theorem, we can calculate the hypotenuse of the triangle, which is equal to the distance from the point of departure. The hypotenuse of the triangle is equal to the square root of (35^2 + 45^2), which is equal to approximately 59.9 miles. Therefore, the distance from the ship's point of departure is approximately 59.9 miles.

For the given data for the reaction, 2 A + 2 B + 4 C => D + E + 3 F, the reaction is zero order in A, second order in B, first order in C and third order overall.

Let the order of reactions be a, b and c for reactions A, B and C respectively.

Then A^{a}B^{b}C^{c} ∝ R

Considering experiment 1 and 2, only concentration of A changes but it has no effect in the total. So a = 0.

Considering experiment 2 and 3, concentration of A and B changes, but it is found that A has no effect. So

(B₃ / B₂)^{b} = (R₃ / R₂)

(0.4/ 0.2)^{b} = (0.008/ 0.002)

2^{b} = 4

Therefore b = 2

Considering experiment 2 and 4

(A₄/ A₂)^{a}(B₄/B₂)^{b}(C₄/ C₂)^{c}= (R₄/ R₂)

(0.4/ 0.2)^{0}(0.6/ 0.2)^{2}(0.2/ 0.4)^{c}= (0.009/ 0.002)
