Answer:

As x --> ∞, then y --> - ∞

Step-by-step explanation:

As the value of x increases(as the graph goes right), the graph seems to go down, meaning the y-values are getting more an more negative. This means that as x approached infinity, the y values approach negative infinity ( x --> ∞, y --> - ∞ ).

As the value of x decreases(going to the left), the graph seems to go higher and higher. Therefore, as x approaches negative infinity, the y-value approach infinity. ( x --> - ∞, y --> ∞ )

Out of the options given, the one As x --> ∞, then y --> - ∞ is true.

Riley has collected approximately 22.7 grams of the trace element in his sample.

To calculate the amount of trace element collected by Riley, we first need to find the volume of the cylinder-shaped container that he used. The formula for the volume of a cylinder is V = πr²h, where V is the volume, r is the radius, and h is the height.

Plugging in the values given in the problem, we get:

V = π(5.7 cm)²(13.6 cm)

V ≈ 1338.6 cubic centimeters

Since the sample contains 0.017 grams of the trace element per cubic centimeter of water, we can find the total amount of trace element collected by multiplying the volume of the sample by the concentration of the trace element:

0.017 grams/cubic centimeter × 1338.6 cubic centimeters ≈ 22.7 grams

Step-by-step explanation:

The derivative of the function f(x) can be found by applying the chain rule. Evaluating f'(x) will yield a new function representing the rate of change of f(x) with respect to x. f'(2) is equal to 128.

To find the derivative of f(x), we apply the chain rule. Let's denote f(x) as u and the inner function x²+5x+4 as g(x). Then, f(x) can be expressed as u², where u=g(x). Applying the chain rule, we have:

f'(x) = 2u * u' = 2(x²+5x+4) * (2x+5)

Simplifying further, we get:

f'(x) = 2(2x²+10x+8x+20) = 4x²+36x+40

To find f'(2), we substitute x=2 into the derivative:

f'(2) = 4(2)²+36(2)+40 = 16+72+40 = 128

Therefore, f'(2) is equal to 128.

Based on the price the computer was reduced by and the profit the shopkeeper still made, if the computer was sold at full price, the profit percentage would have been 50%.

First assume a price the computer was sold at. We'll go with $100.

At this price, the shopkeeper still made a profit of 20% which means that the cost price was;

= 100 / (1 + 20%)

= $83.33

Based on the discounted price of $100, the full price was:

= 100 / (1 - 20%)

= $125

The profit the shopkeeper would have made is:

= (Full price - Cost price) / Cost price x 100%

= (125 - 83.33) / 83.33 x 100%

The lines are perpendicular and the slope of the red line is m₂ = -2/3

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation of line be represented as A

Now , the value of A is

Now , the slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Substituting the values in the equation , we get

Slope m₁ = 3/2

So , the slope of the green line is m₁ = 3/2

Since the lines are perpendicular to each other , the product of their slopes will be equal to -1

And , m₁ x m₂ = -1

So , ( 3/2 ) x m₂ = -1

Multiply by ( 2/3 ) on both sides , we get

The probability that randomly selected individuals will have a mean weight of at least  170 pounds will be 31.56% when men's weights are normally distributed with a mean of 172 lb and a standard deviation of 29 lb (National Health Survey) If 50 men are randomly selected.

Given,

Mean, μ = 172 lb

standard deviation, s = 29 lb

n = 50

and we have to determine: P(x < 170 lb)

Initially, Using the z score formula we find the z value corresponds to a sample mean of 170

z = (x - μ)/(\(s/\sqrt{n}\)) = \(\frac{170-172}{\frac{29}{\sqrt{50} } }\)  = -0.48

Now, using the z table to locate the probability:

P(x < 170) = P(z < -0.48)

or P(z < -0.48) = 0.3156 = 31.56 %

Therefore, the probability that randomly selected individuals will have a mean weight of at least  170 pounds will be 31.56% when men's weights are normally distributed with a mean of 172 lb and a standard deviation of 29 lb (National Health Survey) If 50 men are randomly selected.

What is true about ΔXWZ is that the ratio of its altitude to the corresponding altitude in ΔYWZ is equal to the ratio of the length of XW to the length of YZ.

If ΔYWZ is similar to ΔYXW, it means that these two triangles have corresponding angles that are equal and corresponding sides that are proportional. In this case, we are specifically interested in the altitude of ΔWXZ, which we will denote as h.

Since ΔYWZ is similar to ΔYXW, we can establish the following proportion based on their corresponding sides:

YZ/YX = YW/YW

Let's denote the length of YZ as a and the length of YW as b. We can rewrite the proportion as:

a/YX = b/YW

Now, let's consider ΔXWZ. Since XW is common to both triangles, we can conclude that the altitude of ΔXWZ, which we will denote as k, is also proportional to the altitude of ΔYWZ (h). Therefore, we can express this proportion as:

k/h = XZ/YZ

To establish a relationship between k and h, we need to find a way to relate XZ to YZ. Using the proportion established earlier, we can substitute a for YZ:

k/h = XZ/a

To relate XZ to YZ, we need to find a relationship between XZ and YX. Again, using the similarity of the triangles, we have:

XZ/YZ = XW/YW

Substituting the value of YZ (a) from the earlier proportion, we have:

XZ/a = XW/YW

Now, we can combine the two proportions to find the relationship between k and h:

k/h = (XW/YW) * (YW/a)

Simplifying further, we get:

k/h = (XW/a)

From this equation, we can conclude that the ratio of the altitudes k/h in ΔXWZ and h in ΔYWZ is equal to the ratio of XW to YZ. In other words, the ratio of the altitudes is equal to the ratio of the corresponding sides in the similar triangles.

The level of measurement refers to the properties and characteristics of data that determine the type of statistical analysis that can be performed on that data.

There are four common levels of measurement: nominal, ordinal, interval, and ratio.

(a) Temperature: The level of measurement for temperature is interval. This is because temperature has a fixed unit of measurement, but no true zero point (0°C or 0°F does not mean an absence of temperature).

(b) Allergies: The level of measurement for allergies is nominal. This is because allergies are categorized by different types and names, without any inherent order or hierarchy.

(c) Weight: The level of measurement for weight is ratio. This is because weight has a fixed unit of measurement and a true zero point (0 lbs or 0 kg means no weight).

(d) Happiness level (scale of 0 to 10): The level of measurement for happiness level is ordinal. This is because the scale represents an ordered ranking of happiness, but the intervals between the numbers may not be equal or consistent.

Small plates = y = 10 pounds.

Step-by-step explanation:

Jason and Jerry are competing at a weightlifting competition.

Let us represent the weight of

Large plates = x

Small plates = y

They are both lifting barbells containing 200 pounds of plates. Jason's barbell has 4 large and 10 small plates on it.

4x + 10y = 200.... Equation 1

Jerry's barbell has 6 large and 5 small plates on it.

6x + 5y = 200..... Equation 2

Combining Equations

4x + 10y = 200.... Equation 1

6x + 5y = 200..... Equation 2

We solve using Elimination method

Multiply Equation 1 by 6 and Equation 2 by 4 to eliminate x

24x + 60y = 1200..... Equation 3

24x + 20y = 800.... Equation 4

Subtract Equation 4 from Equation 3

40y = 400

y = 400/40

y = 10 pounds

Solving for x using Equation 1

4x + 10y = 200.... Equation 1

4x + 10(10) = 200

4x + 100 = 200

4x = 200-100

4x = 100

x = 100/4

x = 25 pounds

Therefore, the weight of

Large plates = x = 25 pounds

Small plates = y = 10 pounds.

notice how i made sure the coefficients that have x and y respectively line up.

with this, i can cancel out the x variables by making 2, and -4 as -8 (8+-8=0).

rewrite the equation.

After one year of compounding at a 6% interest rate, you would have approximately $3,180 in your savings account.

To calculate the amount of money you will have in the savings account after one year with compound interest, we can use the formula:

A = P(1 + r/n)^(nt)

Where:

A is the final amount

P is the principal amount (initial deposit)

r is the annual interest rate (as a decimal)

n is the number of times the interest is compounded per year

t is the number of years

Let's solve it step by step:

Given:

P = $3,000 (principal amount)

r = 6% = 0.06 (annual interest rate as a decimal)

n = 1 (compounded annually)

t = 1 (one year)

Using the formula:

A = 3000 * (1 + 0.06/1)^(1*1)

A = 3000 * (1 + 0.06)^1

A = 3000 * (1.06)^1

A ≈ $3180

So, after one year of compounding at a 6% interest rate, you would have approximately $3,180 in your savings account.
